Development patterns of occupational aspirations in adolescents with high-incidence disabilities.Theory-building knowledge of the career behavior of adolescents with high-incidence disabilities and the application of this knowledge to a better understanding of transitions to postsecondary education, work, and adult life has received relatively limited empirical attention (Gregg, 2009; Rojewski & Gregg, 2011). This situation is surprising given the large number of secondary students diagnosed with specific learning disabilities or behavioral behavioral

Estimates place approximately 9% of the U.S. student population as being diagnosed with high-incidence disabilities, representing over two thirds of all high school students that receive special education services (Newman, Wagner, Cameto, & Knokey, 2009).

If the bit is in an audio or video file, it might be detected by the error correction circuitry and either corrected or not, but if not, it is often not noticed by the human rates (Gregg, 2007; Newman et al., 2009), lower postsecondary enrollment and attainment (Stodden, Jones, & Chang, 2002; Wagner, Newman, Cameto, Garza, & Levine, 2005), restricted labor force participation (Barkley, 2006), and lower earnings (Day & Newburger, 2002). Several factors that contribute to these negative transition outcomes include lower self-esteem and a greater sensitivity to the effect of socioeconomic background on academic achievement (Wagner et al., 2005) and career attainment (Barkley, 2006). Reduced familiarity with the exigencies of the workplace, impaired judgment about attainable career goals, and delayed or impaired career maturity (Rojewski, 1996) paint a picture that suggests the presence of substantial obstacles in the career development of adolescents with high-incidence disabilities.
Despite the role that theory plays in explaining the career development and behavior of people without disabilities, as well as the potential that knowledge of career theories holds in supporting the transition planning process, it is surprising that researchers have paid such limited attention to the career choice and behavior of adolescents with high-incidence disabilities in the career development and transition processes. As a result, we focused our analysis on the longitudinal lon·gi·tu·di·nal

Some researchers have voiced disagreement about the actual role aspirations play in eventual job attainment, that is, whether they play a significant role in determining eventual job obtainment. Are aspirations merely reflections of perceived or real opportunity structures (availability of or access to jobs) that are developed and conditioned as a result of life experiences? Whether the role of occupational aspirations is in shaping and guiding educational and career choices or simply in reflecting past experiences, consistent or coherent aspirations do have value as a predictor of future career-related choices and, to a lesser degree, actual career choices (Mau & Bikos, 2000).
Researchers often treat occupational aspirations as a unidimensional construct that is determined by asking people what type of occupation they would choose at some point in the future if they were free of barriers or limiting factors (Rojewski, 2005). Responses to this general question are usually reported either in terms of prestige/status or type of work/interests. Expressing aspirations in terms of prestige or status usually involve a numerical numerical

Indices are typically calculated from information about wages earned, education required, and perceived value to society of each occupation (Stevens & Cho, 1985). These indices result in a hierarchy of occupations where jobs that require higher skills and represent greater value to society are assigned as·sign

Our database was limited to a prestige measure of occupational aspirations, which we adopted as our measurement scheme. Prestige scores, a widely used coding and reporting scheme, offered several advantages for our analysis. First, prestige scores provide a continuous variable that facilitates data analysis. Second, prestige levels reflect people's perceptions about the relative worth, power, and status of occupations. Third, prestige codes may offer some insight into individual estimates of ability and self-concept, as well as societal so·ci·e·tal

Finally, prestige scores are appropriate because they are likely to reflect adolescents' increasing sensitivity to the social evaluation connected to occupations in U.S. society.
Despite the advantages of using prestige scores, we acknowledge certain limitations, most notably how scores are interpreted. For example, because we did not treat aspirations as a reflection of personal values or self-concept, we were limited in our interpretation from venturing into these areas. In fact, a second concern is how to interpret adolescents' aspirations to low- or moderate-prestige occupations. Lower occupational aspirations, by themselves, are not negative. Lowered aspirations may result from realistic assessments of interests, values, abilities, or limited labor market labor market A place where labor is exchanged for wages; an LM is defined by geography, education and technical expertise, occupation, licensure or certification requirements, and job experience openings. Lower prestige occupational aspirations may be negative, however, if young people prematurely or unnecessarily limit their future opportunities or self-imposed limitations early in adolescence (Rojewski, 1996).
Rosenbaum (1981) explained that young people are gradually eliminated from high-prestige occupations through a series of complex interactions and processes. For example, students who do not complete certain academic prerequisites in middle school are often unable to enroll in advanced mathematics and science courses in high school. This, in turn, reduces the possibility of attaining a college degree, which results in diminished di·min·ish

Early adolescents are likely to express high-prestige occupational aspirations, regardless of the likelihood of attaining them. Gradually, aspirations are lowered through compromise as young people realize that they may not .possess necessary skills or abilities, believe that educational or entry-level requirements are beyond their abilities, do not receive support or possess aspirations that are at odds with family and friends, or perceive significant community or societal barriers to job entry or success (Armstrong & Crombie, 2000; Lee & Rojewski, 2009). Occupational aspirations, when measured by prestige levels, are relatively stable during adolescence and provide substantial predictive power The predictive power of a scientific theory refers to its ability to generate testable predictions. Theories with strong predictive power are highly valued, because the predictions can often encourage the falsification of the theory. for later aspirations (Rojewski & Kim, 2003; Rojewski & Yang yang (yang) [Chinese] in Chinese philosophy, the active, positive, masculine principle that is complementary to yin; see yin, under principle. , 1997). When changes do occur, however, people are more likely to compromise their aspirations by shifting between occupations within the same level, rather than between levels (Gottfredson, 2005).
THEORETICAL CONSIDERATIONS FOR OCCUPATIONAL ASPIRATIONS
The development and expression of occupational aspirations can be explained from several perspectives, including developmental (Super, Savickas, & Super, 1996) and status attainment Status attainment or status attainment theory deals largely with one’s position in his or her society. The idea behind status attainment is that one can be mobile, either upwardly or downwardly, in a form of class system. theories (Hotchkiss & Borow, 1996). Although presenting different theoretical positions, both perspectives explain that aspirations reflect people's assessments of personal capabilities and available opportunities. Aspirations are also influenced by personal and societal characteristics, including gender and socioeconomic status (SES). The theory supporting our analysis, Gottfredson's (2005) theory of compromise and circumscription cir·cum·scrip·tion

2. Something, such as a limit or restriction, that circumscribes.

Gottfredson (2005) viewed vocational choice as a process of matching one's career interests with individual skills and abilities. To accomplish this process successfully, young people must navigate (1) "Surfing the Web." To move from page to page on the Web.

Outcomes of this developmental stage include a positive self-concept (including children's awareness of their emerging talents, skills, and interests)and an understanding about the world of work and the types of occupations available leading to the beginnings of a cognitive map Cognitive maps, mental maps, mind maps, cognitive models, or mental models are a type of mental processing (cognition) composed of a series of psychological transformations by which an individual can acquire, code, store, recall, and decode information about the relative locations of aspirations.

tol boundaries, based on levels of acceptable effort and occupational alternatives.
* Gottffedson's (2005) third stage occurs from 9 to 13 years of age and is known as circumscription, which refers to eliminating occupations that conflict with one's self-concept. The act of eliminating certain career options while retaining others results from childhood experiences defined by an orientation to size and power (3-5 years of age), sex roles (6-8 years of age), social valuation/prestige (9-13 years of age), and unique self/interests (14 years of age and older). Circumscription involves the progressive elimination of occupations deemed unacceptable.
* The final stage, compromise, occurs when young people relinquish their most preferred occupations for less compatible but more accessible ones. Together, circumscription and compromise contribute to a zone or range of acceptable occupational alternatives considered to reflect where people feel they fit in society.
From Gottfredson's perspective, occupations can be arranged to reflect social hierarchies by sex type, prestige, and interests. During the career-compromise process, occupations are eliminated in reverse order of their acquisition or in relation to how close the occupation reflects a person's core self-concept. Interests, which are incorporated into the self-concept last, are compromised first. Orientation to prestige is incorporated into the self-concept before interests but after sex type, and is compromised second. Sex type is closest to the core self-concept since it is incorporated first, and is the last dimension to be compromised. Our analysis focused on aspirations as measured by prestige scores, and the development of aspirations over time.
LONGITUDINAL NATURE OF 0 CCUPA TIONAL ASPIRA TIONS
Gottfredson's (2005) theory of career compromise and circumscription framed our understanding of the development of occupational aspirations. Little research is available, however, to explain how occupational aspirations develop and change over time. Even less is known about occupational aspirations for adolescents and young adults with high-incidence disabilities. Two studies that have examined this issue for people without disabilities are Rojewski and Yang (1997) and Lee and Rojewski (2009).

A structural equation model found aspirations to be relatively stable across the 4-year time period studied. Structural coefficients indicated that SES had a significant effect.

The researchers noted two distinct trajectories, separated by high school graduation Graduation is the action of receiving or conferring an academic degree or the associated ceremony. The date of event is often called degree day. The event itself is also called commencement, convocation or invocation. :
* During high school an increasingly positive trajectory in occupational aspirations was observed from Grade 8 to 12. Almost three fourths (73.1%) of the total change in aspirations prestige scores occurred between Grade 8 and 10, whereas the remaining one quarter (26.9%) of the positive growth happened between Grade 10 and 12.
* After high school graduation, a negative trajectory in occupational aspirations was revealed. As young adults, one third of the total negative change in aspiration prestige scores occurred between high school graduation and 2 years post-high school, and a majority of the total change in aspirations (67.4%) happened during the period of 2 to 8 years post-high school completion.
Interestingly, young women had higher occupational aspirations in high school, but were more likely to lower their aspirations after graduation than their male peers. SES had a significant influence on Grade 8 aspirations, but did not impact the rate of change (Lee & Rojewski, 2009).
INFLUENCE OF SELECTED VARIABLES ON TRAJECTORY OF OCCUPATIONAL ASPIRATIONS
We identified several factors to include in our longitudinal latent growth curve model, including gender, SES, academic achievement, and two concepts connected to the idea of self-determination, locus of control and self-concept. Not only have these variables been identified as factors in career development and choice, but they have also been implicated im·pli·cate

Gender has been a prominent factor in research on occupational aspirations. Male adolescents are more likely to aspire to aspire to

These differences, coupled with lower occupational attainment for females, have led some to conclude that gender is one of the most powerful and persistent influences on occupational development (Gottfredson, 2005; Mello, 2008; Rojewski, 1996, 1999; Rojewski & Yang, 1997).
Despite contradictory findings regarding the influence of SES on occupational aspirations (e.g., Garg, Kauppi, Lewko, & Urajnik, 2002), it appears that SES has a positive influence, either directly or indirectly, on aspirations (e.g., Lee & Rojewski, 2009; Mau & Bikos, 2000; Rojewski & Yang, 1997). Usually, adolescents from higher SES backgrounds aspire to more prestigious occupations than those from lower class backgrounds. Though the role of SES on the development of occupational aspirations can be quite strong, its influence is likely to occur by early adolescence. Once incorporated into longitudinal models, SES does not appear to present any long-term influence on aspirations formation.
Many researchers have posited that educational aspirations and academic achievement are central to an understanding of career development and choice (Arbona, 2000; Mau & Bikos, 2000; Rojewski, 1999; Rottinghaus, Lindley, & Green, 2002). In fact, Mau and Bikos (2000) declared that academic achievement was perhaps the single best predictor of occupational aspirations. The influence of academic achievement on career behavior is best viewed as a complex set of interactions where strong academic achievement encourages high educational goals, which encourage engagement in opportunities to acquire advanced education. Additional education and doing well over a long period allow for greater occupational possibilities in adulthood. By contrast, lower achievement may dampen educational goals, which may preclude involvement in certain academic activities and limit future occupationally-related opportunities and experiences (Arbona, 2000; Wang & Ma, 2001).
Several studies support the connections between academic achievement and occupational aspirations. Rojewski and Yang (1997) reported that academic achievement had a modest but positive influence on aspirations that was strongest in Grade 8 but decreased over time. Several studies focusing on adolescents deemed at risk of school failure (Rojewski, 1995; Rojewski & Hill, 1998) reported that students at minimal academic risk were more likely to report higher prestige occupational aspirations, whereas those at substantial risk of academic failure were more likely to aspire to lower prestige occupations.
Self-determination, the idea that adolescents with disabilities should advocate and act on their own behalf, is not only an important component in planning for and implementing educational programs while in school, but also when considering educational and occupational futures once school is completed. The database we used for our analysis did not afford us measures of self-determination such as indicators of self-assessment, self-advocacy, or self-reflection. The database did contain a measure of locus of control, which we included in our model. Locus of control is the degree to which people perceive positive or negative events as being a consequence of their own actions and under personal control. People are judged internally controlled if they believe they exert control over their successes and failures, whereas externally controlled people attribute their performance to outside forces beyond their control (Hallahan & Kauffman, 1997). A person with an external locus of control views career decisions in terms of contextual influences and is more likely to be passive to changes in those contexts. Externally controlled people are likely to base career decisions on peer influences, labor market trends, and so forth. External locus of control has been reported for adolescents with high-incidence disabilities (Dowdy dow·dy

2. Old-fashioned; antiquated.
n. pl. , Carter, & Smith, 1990) and may also play a role in shaping occupational aspirations (Gottfredson, 2005; Rojewski & Yang, 1997).
The self-esteem construct is relatively stable. Rojewski and Yang (1997) found that self-esteem had only a minimal effect on occupational aspirations in early adolescence, which diminished throughout high school. In contrast, Patton and Creed (2007) reported that high-achieving students were not only more career mature and had higher self-esteem, but were also more likely to aspire to professional-status occupations than students who held lower skilled aspirations. It is likely that self-esteem may influence occupational aspirations and be especially relevant to people with high-incidence disabilities because poor self-esteem and low self-concept caused by repeated failure, limited social skills, or difficulty serving as a self-advocate are often cited as major problems for this population (Dowdy et al., 1990).
Given the importance of occupational aspirations with respect to postsecondary transition outcomes, an analysis of factors that influence the development of occupational aspirations is essential. The need for analysis is intensified in·ten·si·fy

We investigated this issue by integrating prominent factors posited to affect the formation of occupational aspirations from Grade 8 to 8 years post-high school graduation (see Figure 1).
DATABASE SELECTION AND TREATMENT
The National Education Longitudinal Study of 1988 (NELS:88). Data from the NELS:88 (National Center for Educational Statistics, 2002), administered by the National Center for Educational Statistics of the U.S. Department of Education, was used for this analysis. NELS:88 contains nationally representative, longitudinal data designed for the study of the educational, vocational, and personal development of adolescents and young adults. The database includes an initial two-stage stratified stratified /strat·i·fied/ (strat´i-fid) formed or arranged in layers.
Arranged in the form of layers or strata. cluster sample of approximately 25,000 adolescents attending 1,052 schools (815 public and 237 private) nationwide followed at 2-year intervals since 1988 (base year-8th grade, first follow-up-10th grade, second follow-up-12th grade, third follow-up-2 years postsecondary, fourth followup-8 years postsecondary). Data sources include various combinations of school administrators, parents, teachers, and students at each data collection point (Curtin, Ingels, Wu, & Heuer, 2002).
[FIGURE 1 OMITTED]
Cautions. Though the NELS:88 database provided an excellent opportunity to examine the questions we posed, one issue related to identification of people with learning disabilities and behavioral disorders posed a challenge, that is, the initial exclusion of some students with physical or mental disabilities. Ingels et al. (1994) reported that 5.4% of eligible participants were excluded in the base year because survey instruments were deemed unsuitable. Almost half (140 of 322), however, were eventually reassessed, deemed eligible, and integrated into the sample. Ingels and Scott (1993) concluded that the overall biasing effect caused by undercoverage for people with disabilities was relatively small. Even so, the possibility exists that some students with learning disabilities or behavioral disorders were excluded from participation. Although the NELS:88 database was not designed to look at adolescents with disabilities, the data offers an important resource for studying the career issues of this population because it is nationally representative, longitudinal, and provides extensive amounts of data (Hodapp & Krasner, 1994-1995; Reschly & Christenson, 2006; Rossi, Herting, & Wolman, 1997).
IDENTIFICATION OF STUDENTS WITH HIGH-INCIDENCE DISABILITIES
The NELS:88 database offers information from students, parents, teachers, and school officials that can determine the presence of a disability. Of all these sources, parent-derived responses to two base-year questionnaire items determining the presence of a disability and receipt of disability-related services provide the most stable and reliable sources of information (Hodapp & Krasner, 1994-1995; Ingels & Scott, 1993). This definition was applied to our analysis. Thus, our sample includes all young people in the NELS:88 database whose parents reported that their child had a learning disability or behavioral disorder behavioral disorder Psychiatry A disorder characterized by displayed behaviors over a long period of time which significantly deviate from socially acceptable norms for a person's age and situation and had received one or more disability-related services.
To examine the effect of selected covariates on the trajectory of occupational aspirations, adolescents had to meet our established eligibility criteria (i.e., positive parental responses to two disability-related base-year (BYP BYP Bypass

The initial sample size totaled 585 and included 341 male (58.29%) and 244 female (41.71%) adolescents. A total of 462 (78.97%) were reported as possessing a learning disability (BYP47G) and receiving one or more disability-related services, and 100 (17.09%) were reported as having a behavioral disability (BYP48G) and receiving at least one disability-related service (BYP48H). (Note: in BYP47G and BYP48H, the numerals and the alphabetic designations are simply the item numbers for parent responses.) Another 23 (3.93%) students had both a learning disability and a behavioral disorder, which we included in the behavioral disorder (BD) group. Inclusion of dually identified students in the BD group was based on the federal definition of learning disabilities (LD), which states that when LD occurs concomitantly con·com·i·tant

Thus, our BD group contained a total of 123 (21.03%) young people. Table 1 provides further information about participants' demographic characteristics.
Our data were taken from all five waves of the NELS:88 database. This section briefly describes how these variables were measured.
Demographic Variables. Demographic variables included gender (male = 0, female = 1) and high-incidence disability (behavioral disabilities = 0, learning disabilities = 1). Standardized SES scores (M = -.039, SD = .043) using family income, parents' education levels, and parents' occupations (Owings et al., 1994) were used.
Self-Esteem. Self-esteem was measured using three statements similar to items developed by Rosenberg (1965). Participants self-rated the following statements describing themselves, "I feel good about myself," "I am a person of worth, equal of others," and "On the whole, I am satisfied with myself." Response options ranged from 1 (Strongly agree) to 4 (Strongly disagree). An internal consistency In statistics and research, internal consistency is a measure based on the correlations between different items on the same test (or the same subscale on a larger test). It measures whether several items that propose to measure the same general construct produce similar scores. reliability coefficient coefficient /co·ef·fi·cient/ (ko?ah-fish´int)
1. an expression of the change or effect produced by variation in certain factors, or of the ratio between two different quantities.
2. of .687 was obtained.
Locus of Control. Locus of control was measured using three statements similar to items used by Rotter (1966). Participants self-rated the following statements describing themselves, "Every time, I try to get ahead, something or somebody stops me," "My plans hardly ever work out, so planning only makes me unhappy," and "Chance and luck play an important role in my life." Response options ranged from 1 (Strongly agree) to 4 (Strongly disagree). An alpha coefficient for internal consistency was .587.
Academic Achievement. The Educational Testing Service The Educational Testing Service (or ETS) is the world's largest private educational testing and measurement organization, operating on an annual budget of approximately $1.1 billion on a proforma basis in 2007. (ETS ETS Educational Testing Service (nonprofit private educational testing and measurement organization)

ETS Engineering (&) Technical Services ) was commissioned to develop academic achievement tests in reading, mathematics, science, and history/citizenship/geography throughout the NELS study. We used standardized reading, mathematics, and science achievement scores at Grade 8 to indicate academic achievement in our analysis. Twenty-one multiple-choice items that consisted of five separate reading passages measured Grade 8 reading achievement, with an internal consistency reliability coefficient of .84. The base year mathematics achievement test contained 40 multiple-choice items covering algebra algebra, branch of mathematics concerned with operations on sets of numbers or other elements that are often represented by symbols. Algebra is a generalization of arithmetic and gains much of its power from dealing symbolically with elements and operations (such as , arithmetic, geometry geometry [Gr.,=earth measuring], branch of mathematics concerned with the properties of and relationships between points, lines, planes, and figures and with generalizations of these concepts. , data/probability, and advanced topics and possessed an internal consistency reliability coefficient of .90. Grade 8 science achievement tests consisted of 25 multiple-choice items covering earth, life chemistry, and the scientific method and had a reported internal reliability coefficient of .75 (Rock & Pollack pollack: see cod.
Either of two commercially important North Atlantic species of food fish in the cod family (Gadidae). , 1991).
Occupational Aspirations. Occupational aspirations were assessed by asking individuals to indicate the job they expected to have at age 30 from a listing of 17 (8th grade), 19 (10th grade), 19 (12th grade), 30 (2 years after high school), and 42 (8 years after high school) major occupational categories. Responses were coded using socioeconomic index (SEI) codes calculated by Stevens and Cho (1985) assigning these categories a continuous score (Hotchkiss & Borow, 1996). For example, occupations such as "homemaker" or "not working" were assigned a SEI value of 15.71 (lowest score), and occupations in the "science, engineering, or professional" professions were assigned SEI values of 68.51. Similar coding decisions were made for all remaining occupations. SEI scores were transformed by dividing them by 10 to facilitate statistical analysis. SEI mean scores across the five time points were 4.322 (SE = .099), 4.667 (SE = .084), 4.734 (SE = .106), 4.455 (SE = .090), and 4.205 (SE = .089), respectively.

(MI) was used to replace missing values In statistics, missing values are a common occurrence. Several statistical methods have been developed to deal with this problem. Missing values mean that no data value is stored for the variable in the current observation. for selected covariates and occupational aspirations. Ten separate multiply-imputed data sets were created. MI assumes that data are at least missing at random, meaning that the probability of missing data on observed variables is associated with some observed variables in the model but not with being missing itself. Although the missing-at-random assumption cannot be tested statistically, we examined correlations between the indicators of missing values for each variable with every other variable. We found that the finding of being missing for most variables was not associated with each other (r < .25), except for scores on science achievement, which were highly associated with data being missed on items that measured self-esteem and locus of control (r = .678). Therefore, we eliminated the science achievement variable. As a result, we ended up with a construct of academic achievement explained by reading and mathematics achievement scores.
As a preliminary step, we plotted mean occupational aspiration prestige scores of the gender--disability type subgroups at each of the five data collection points (see Figure 2). Overall, occupational aspirations expressed by young people in our sample were in the moderate to moderate-high prestige range. Of particular interest in this analysis, however, was the trajectory of aspirations over time. We noted several interesting descriptive patterns.
[FIGURE 2 OMITTED]
Females with learning disabilities reported higher prestige aspirations than did males with learning disabilities through the data collection period. Females with learning disabilities, however, expressed their highest aspirations in 10th grade, whereas males with learning disabilities reported their highest aspirations in the 12th grade. Females with behavioral disorders also reported higher aspirations than their male peers with behavioral disorders at each data point. Though the general trend line for males with behavioral disorders was roughly curvilinear curvilinear

MODEL SELECTION AND ALTERNA TIVE MODELS
We first examined time-specific occupational aspiration prestige mean scores. Mean values increased until the third time point and then showed a downturn Downturn

Considering this curvilinear trend, as well as the explicit transition represented between the third and fourth time points--the period between high school graduation and 2 years post-high school--a piecewise latent growth model was selected. Piecewise trajectory modeling is used when the trajectory shows a combination of two or more linear trends (Bollen & Curran, 2006). Because our model showed two trends, the rates of mean change between time points were not equal, and data were collected at inconsistent time points during the third and fourth follow-ups, we adopted a piecewise growth model with freely estimated loadings.
Our model showed two trends. Prior to the transition, the slope for the first time point (Grade 8) was fixed at zero; and the third time point (Grade 12) at 1. The slope for the second time point (Grade 10) was freely predicted. After the transition, the slope for the third time point (Grade 12) was fixed at zero, and the fifth point (8 years after high school) at 1. The slope for the fourth time point (2 years after high school) was estimated freely. Because no significant difference between a model with equal variances and one with unequal variances was found [[DELTA][chi square chi square (kī),

To assess the overall latent growth model fit to the data, we used chi-square statistics, as well as the following indices with recommended cutoff criteria: SRMR SRMR Security Risk Management Review

It provides a common language to a transport protocol and allows client/server applications to be used in different networking environments. [greater than or equal to] .90 (Hu & Bentler, 1999; Marsh, Hau, & Wen, 2004). The overall fit indices strongly suggested that the hypothesized model fit the data well [[chi square](8, N = 585) = 8.529, p = .384; SRMR = .035; RMSEA = .011 (a 90% confidence interval confidence interval,

When total growth in occupational aspirations before high school completion was set at 1, 93.4% of total positive change was achieved between Grades 8 and 10, whereas 6.6% of the total positive change occurred between Grades 10 and 12. When setting total growth in occupational aspiration from the 12th grade to 8 years after graduation at 1, 38.5% of the total negative change was observed between Grade 12 and 2 years after graduation, while 61.5% of the total negative change was obtained during the period between 2 and 8 years after graduation. The intercept of the unconditional model was 4.323, indicating that, on average, occupational aspiration scores were 4.323 units in the eighth grade. Before high school completion, the average rate of change in the slope was .374. This means that on average, students with high-incidence disabilities aspired to occupations with medium-level prestige requiring at least some college education. (These numbers reflect transformed SEI scores [Stevens & Cho, 1985] and can be easily converted to their original state by multiplying them by 10 to counteract our transformation to support analysis. An SEI score of 43.23 reflects a medium level of prestige.) Aspiration scores increased .343 points between Grades 8 and 10, but scores increased only .180 points between Grades 10 and 12. After high school, the average rate of change in slope was -.510, meaning that, on average, occupational aspiration scores decreased .510 points by 8 years after high school. Occupational aspiration scores decreased .204 points between Grade 12 and 2 years after high school completion, whereas scores decreased .305 points between 2 years after high school and 8 years after high school. Both the mean intercept and mean slopes differed significantly from zero (p < .001).
Statistical significance for the variance of intercept (1.852) and slope (1.185 for pretransition) suggested participants varied in their initial occupational aspiration scores and their rates of change. However, the variance of slope for posttransition (.885) did not significantly vary. The statistically significant negative covariance Covariance

A negative covariance means returns vary inversely. between the intercept and slope for the pretransition period (-.695; r = -.462) implied that young people with higher initial aspirations had relatively slower change than did those with lower initial aspirations. [R.sup.2] values were .444, .408, .417, .380, and .404, respectively, indicating that variability in occupational aspiration scores explained by the underlying latent growth factors ranged from 38% to 44%.

To test the effect of covariates on latent growth factors, we first fixed the freely estimated slopes for the second time point (Grade 10) and the fourth time point (2 years after high school graduation) at .934 and .385, respectively. Next, gender, disability status, SES, locus of control, self-esteem, and eighth-grade academic achievement were introduced to the unconditional piecewise growth model. Before testing our hypothesized model, we first tested whether the measurement model (i.e., all variables and growth factors were correlated cor·re·late

2. ) fit the data well. Overall, model indices indicated the model fit the data well [[chi square](2(79, N = 585) = 97.235, p = .080; SRMR = .039; RMSEA = .020 (a 90% confidence interval of.000 and .032); CFI = .985; and TLI = .977].
The chi-square model fit of the conditional model showed a good fit to the data [[chi square](80, N = 585) = 98.999, p = .074]. Also, overall model fit indices suggested that the model fit the data well [SRMR = .039; RMSEA = .020 (a 90% confidence interval of .000 and .032); CFI =.984; and TLI = .977]. The only covariate significantly associated with the intercept factor was academic achievement (.076), indicating that adolescents with higher academic achievement had higher aspirations in Grade 8. The standardized estimate for academic achievement on the intercept factor (.329) was approximately three times greater than SES (.108) or gender (.108). Although locus of control was not significantly associated with the intercept, the standardized estimate for this path (.263) was almost as large as academic achievement. The prior-slope (growth before high school completion) was significantly associated only with SES (.418), indicating that higher SES was associated with a positive change in the slope of occupational aspiration scores across the three time points before high school completion. Specifically, one-unit increase in SES was associated with a .418-unit increase in the pretransition slope. Moreover, a level of SES one standard deviation above the mean was associated with a prior-slope level about .30 standard deviations above the mean, controlling for other covariates on the prior-slope factor. The magnitude of the standardized estimate for locus of control on the intercept factor was greater than for other covariates, except for academic achievement, on the intercept. The magnitude of the locus of control standardized estimate on the prior-slope factor was two times greater than other covariates.
After high school, only disability status had a significant association with aspiration growth rate. The conditional mean slope was .675 units lower for individuals with learning disabilities than for those with behavioral disorders. The estimated standardized estimate for the direct effect of disability status on the post-slope factor was -.308, controlling for other covariates. After including covariates, [R.sup.2] values at each time point were .439, .403, .412, .377, and .405, respectively, indicating that the proportion of the observed variability in occupational aspirations explained by the underlying latent growth factors ranged from 38% to 44%. The inclusion of covariates explained 31% of the variance of the intercept factor, and 20% and 15% of the variances of the prior- and post-slope factors, respectively. Table 4 shows coefficient estimates and standard errors for the effects of covariates on the intercepts and slopes.
OVERALL FIT OF THE MODEL
In the unconditional model, overall fit indices indicated that the hypothesized model fit the data well. All parameter estimates were consistent with the hypotheses, and [R.sup.2] values were reasonable. After including covariates with latent variables, overall model fit indices were still reasonable and suggested that the model fit the data well. [R.sup.2] values were similar to the unconditional model and standard errors were not large. We tried to check the modification indices, but our use of multiple imputation data sets did not support this analysis. Although some path coefficients were not statistically significant, these paths were not critical to our model. Overall, the conditional piecewise latent curve model with equal error variances had a reasonable and stable fit.
Several interesting findings emerged from our analysis, including information about the long-term trends and changes in occupational aspirations, and the influence of selected factors on both the development and trajectories of the occupational aspirations of our target population.
TRAJECTORIES AND CHANGE IN O CCUPA TIONAL ASPIRA TIONS
Perhaps the most important outcome of this study revealed the trajectory of occupational aspirations for people with high-incidence disabilities. We expected to find aspiration change patterns similar to those reported for adolescents without disabilities (Lee & Rojewski, 2009), albeit lower in prestige scores (Kortering, Braziel, & McClannon, 2010; Rojewski, 1996, 1999). Our analysis revealed this to be the case. In general, we found a curvilinear trajectory of occupational aspirations that started in the eighth grade with a positive trend continuing through high school, at which point a negative trend began that existed until data collection ceased 8 years after high school completion. Closer visual inspection of occupational aspiration patterns, based on gender-disability type interactions, however, revealed more chaotic and disruptive disruptive /dis·rup·tive/ (-tiv)

2. causing confusion or disorder. patterns. This was particularly true for young people with behavioral disorders, and especially so for females with behavioral disorders.
Lower prestige aspirations are not necessarily a negative outcome for people with or without disabilities. As a group, however, the occupational aspirations of young people with high-incidence disabilities were consistently lower in prestige than the aspirations of their peers without disabilities, indicating more restricted postsecondary work and education options. These self-imposed restrictions occurred early and were, for the most part, consistent throughout our analysis timeframe. Thus, it appears that people with high-incidence disabilities are more likely to restrict their boundaries of tolerable effort (Gottfredson, 2005). Gottfredson theorized that people rule out occupations if they are considered to be too difficult to attain with reasonable effort or pose too high a risk of failure. The boundary of tolerable effort is based to a large extent on academic ability.
Academic ability, and perhaps academic self-efficacy (Baird, Scott, Dearing, & Hamill, 2009), is key to understanding the results we obtained. Although we did not directly study the link of academic achievement (ability) to occupational aspirations, the connection between the two has been well established (Hotchkiss & Borow, 1996). It is likely that the connection between educational difficulties typically experienced by adolescents with high-incidence disabilities and restricted (lower prestige) occupational aspirations may play an important role in understanding our results, because prestige ratings of occupations are based, in part, on required levels of education (Stevens & Cho, 1985). We speculate that the lowered aspirations observed throughout the time-span of our analysis was the result, in part, of the academic difficulties experienced by adolescents with high-incidence disabilities throughout middle and high school. Thus, these aspirations may be perceived as realistic in terms of acknowledging academic difficulties, but may also reflect feelings of academic frustration or limited academic self-efficacy. The latter may be especially true in light of the fact that most of the high-incidence disability group in our analysis would have had average or near-average intelligence. If this is true, then the lower prestige occupational aspirations reported may have been unnecessarily restrictive, based on individuals' perceptions of their academic limitations or negative academic self-efficacy. Because this is speculative, additional investigation is warranted to address this important issue.
The rate of change in occupational aspirations was somewhat unexpected. In our analysis, over 90% of change in adolescents' expressed aspirations occurred between the eighth and 10th grades. Thus, it appears that adolescents with high-incidence disabilities are more likely to restrict their occupational (and educational) futures at an early age. This premature restriction could explain problems often reported for this population, such as lower postsecondary enrollment and attainment (Stodden et al., 2002; Wagner et al., 2005) and restricted labor force participation (Barkley, 2006). Rojewski (1996) suggested that even though adolescents with disabilities may raise their aspirations as they progress through high school, this may often be too late to attain basic educational prerequisites or occupational experiences needed to prepare for or enter certain advanced career paths.

Future investigations should examine the role of special education services on supporting the career-related needs of adolescents with disabilities during this turbulent time. Our data could not determine whether the lack of positive change in aspirations during high school resulted from a lack of school support services support services Psychology Non-health care-related ancillary services–eg, transportation, financial aid, support groups, homemaker services, respite services, and other services that emphasized self-determination and career/transition planning, or from the effects of academic delay and poor self-esteem or bias. These are critical issues, given changes in educational policy regarding transition planning and implementation.

We chose the Socioeconomic Index (SEI) developed by Stevens and Cho (1985) to code the prestige of occupational aspirations. The SEI is an established measure of occupational prestige and, while advantages to using this approach outweigh out·weigh

2. To be more significant than; exceed in value or importance: The benefits outweigh the risks. disadvantages, the scheme often groups together individual occupations into broader categories for coding purposes. For example, various engineering- or science-related occupations all receive the same SEI code, based on prestige, even though each distinct occupation might receive different codes if government or work personality coding schemes were used. Therefore, it is likely that our broader approach to coding obscured some movement in expressed aspirations over time.

In our sample, the bulk of change in aspiration prestige scores occurred between the eighth and 10th grades, suggesting that adolescents with high-incidence disabilities prematurely restricted their career options.

The early occurrence of restrictions to aspirations is especially troubling in that the adolescents we studied experienced this phenomenon before they had even entered high school when career-related programs are more likely to be available.
Possible interpretations of stagnant or stable occupational aspirations from 10th to 12th grades could include identified career choices and plans, or reflections of perceived barriers and bias inherent in school or the work community.

Gottfredson (1986) suggested that cultural or social isolation and differential treatment that often accompanies special group status lead to restricted experiences and opportunities and can contribute to lowered occupational aspirations.
The time immediately after high school completion can be a difficult time of adjustment for all adolescents, but particularly so for individuals with disabilities (Barkley, 2006; Day & Newburger, 2002; Stodden et al., 2002; Wagner et al., 2005). A negative or downward trend, which was not unexpected, represents movement toward less prestigious but more accessible occupations, and is an appropriate adjustment to occupational goals. This activity likely results from crystallizing career interests, assessing strengths and abilities, encountering work-related challenges and competition, and recognizing educational and career opportunities or barriers.

However, only about one third of the negative trend in expressed aspirations was observed during the first 2 years after high school, whereas the remainder occurred from 2 to 8 years postsecondary. Our analysis did not determine why this pattern of career compromise occurred. We did not consider activities that might delay career decision-making such as postsecondary education, vocational training, or decisions that might make career compromise a moot point moot point n. 1) a legal question which no court has decided, so it is still debatable or unsettled. 2) an issue only of academic interest.

INFLUENCE OF SELECTED FACTORS ON OCCUPATIONAL ASPIRATIONS
We were somewhat surprised to find what was and was not significant when the influence of selected variables on the development and trajectory of occupational aspirations was examined. For example, academic achievement was the only factor that was significant in explaining occupational aspirations before high school completion. Adolescents with higher academic achievement generally reported higher aspirations. This connection, however, was evident only in the eighth grade. Past studies that looked at the occupational aspirations of adolescents with learning disabilities (Rojewski, 1996, 1999) and of a sample of adolescents without disabilities (Lee & Rojewski, 2009) from longitudinal perspectives did not report a similar influence for achievement. However, connections between academic achievement (Arbona, 2000; Lent Lent [Old Eng. lencten,=spring], Latin Quadragesima (meaning 40; thus the 40 days of Lent). In Christianity, Lent is a time of penance, prayer, preparation for or recollection of baptism, and preparation for the celebration of Easter. , 2005) or educational aspirations (Rojewski & Yang, 1997) and occupational aspirations have been made.
The academic achievement--occupational aspirations connection makes sense when considering the highly academic nature of high-incidence disabilities, particularly learning disabilities. A heightened focus on academics experienced by most middle school students might take on added emphasis for those young people who are involved in developing individualized in·di·vid·u·al·ize

After high school, disability status was significant in explaining occupational aspirations. This may be attributable to differences in the trends we observed for young adults with behavioral disorders and learning disabilities. Throughout the data-collection period, young people with learning disabilities had a trajectory much more like people without disabilities, only lower. People with behavioral disorders had aspirations patterns that were increasingly divergent di·ver·gent

4. from their peers with learning disabilities.
We expected gender to have some influence on occupational aspirations, particularly in early adolescence. However, no statistically significant gender differences were detected. Females expressed higher aspirations at all data points, but also presented greater score variability than their male counterparts. Even so, the literature has consistently shown that females with disabilities tend to experience poorer occupational outcomes than their male counterparts (Wagner et al., 2005).
Initially, we were puzzled to find that SES did not present consistent effects on occupational aspirations but varied depending on whether we considered aspirations at separate data points or the trajectory of aspirations over time, specifically the prior-slope (i.e., Grades 8-12). Interestingly, these findings are directly opposite of those reported from a sample without disabilities taken from the same database (Lee & Rojewski, 2009). Past studies of people with learning disabilities (Rojewski, 1996, 1999) and samples without disabilities (Lee & Rojewski, 2009; Rojewski & Yang, 1997) have shown SES to have an early and persistent influence on occupational aspirations. That early influence was not observed in our results. It is possible that support services offered through special education during early school grades may provide some type of moderating effect on the influence of SES on occupational aspirations for these early adolescents with high-incidence disabilities. In other words Adv. 1. in other words - otherwise stated; "in other words, we are broke"
put differently , special education might initially reduce or smooth over the potential negative effects of SES on the development or expression of aspirations during middle school. Regardless, SES did negatively affect the long-term development of aspirations. The overall low level of SES in our sample may have contributed to this anomalous a·nom·a·lous

Whatever the reason, future study should examine the role of special education in elementary grades to the formation of occupational aspirations and the diminished influence of SES in adolescence, which has not, to date, been anticipated or considered.
Finally, we examined several factors that had some connection to the broader concept of self-determination, that is, the notion that people with disabilities should advocate and act on their own behalf when planning for and implementing their future (Wehmeyer et al., 2007). One of the measures selected, locus of control, exerted a relatively strong effect on occupational aspirations in the eighth grade, even though results were not significant. Given limited attention on the role of self-determination on career issues for adolescents with disabilities and the possible connections indicated by our findings, we believe that further investigation on this topic is warranted.
One strength of this study was the use of a large nationally representative longitudinal database to examine the influence of certain factors on the (a) formation of and (b) developmental changes in occupational aspirations of individuals with high-incidence disabilities at five points over a 12-year period spanning from adolescence through early adulthood. Whereas results contribute to our understanding of this phenomenon, additional questions remain unanswered. For example, the question of whether special education services enhance or dampen the career behavior of this population in middle and high school has not been adequately examined.

2. area for future study and seems essential when considering the importance of transition planning. Another area that warrants continued attention is the role of disabilities on career development. It seems clear that the presence of high-incidence disabilities altered occupational aspirations patterns in our study, but reasons for these deviations are not clear. Further work is needed to determine the influence of both psychological and sociological factors on the career behavior and transition preparation of adolescents and young adults with high-incidence disabilities.
