The Multidimensional Character of Biased Perceptions of Individuals with Disabilities.The Americans with Disabilities Act Americans with Disabilities Act, U.S. civil-rights law, enacted 1990, that forbids discrimination of various sorts against persons with physical or mental handicaps. of 1990 has sensitized sensitized /sen·si·tized/ (sen´si-tizd) rendered sensitive. sensitized rendered sensitive. sensitized cells see sensitization (2). many individuals in business and industry to the fact that discrimination aimed at individuals with disabilities is as unjust UNJUST.

The Civil Rights Act of 1964 and the moral consciousness it aroused helped eliminate many of the discriminatory dis·crim·i·na·to·ry adj. 1. Marked by or showing prejudice; biased. 2. Making distinctions. dis·crim employment practices directed toward minorities. Individuals with disabilities have not been as fortunate in terms of employment over the past 35 years. While African-Americans and other racial minorities have made gains toward equality in employment, a significant percentage of the American disabled population remains unemployed. The Senate Committee on Labor and Human Relations human relations npl → relaciones fpl humanas reported that 67% of individuals with disabilities between the ages of 16 and 64 are unemployed (Simpkins & Kaplan, 1991). Fifty-eight percent of all disabled men and 80% of all disabled women are unable to find gainful gain·ful adj. Providing a gain; profitable: gainful employment. gain ful·ly adv. employment (Thornburgh, 1991). Furthermore, Harris and Associates (cited
in Satcher & Hendren, 1991) found that approximately 66% of the
unemployed individuals with disabilities that they surveyed wanted to
work, suggesting that these unemployment figures do not simply reflect
self-selection out of the workforce.Despite such statistics, most research on discrimination in the workplace has continued to center on either race or gender-based discrimination. Little research is found on determining the current level of discrimination or on determining the possible causal and/or mediating variables that lead to the biased perceptions of an individual with a disability. An additional concern regarding much of the research on bias and discrimination is that many scales designed to measure attitudes toward individuals with disabilities rely on unidimensional u·ni·di·men·sion·al adj. One-dimensional. Adj. 1. unidimensional - relating to a single dimension or aspect; having no depth or scope; "a prose statement of fact is unidimensional, its value being measured wholly in terms measures of affect toward the "disabled." Scale developers have concentrated on unidimensional measures that seem to assume constant "bias potential" within and even across disabilities. That is, an assumption is made that individual's with a given disability are perceived similarly by a non-disabled individual. This approach also often makes the unlikely assumption that individual's with vastly different disabilities are perceived equally by the non-disabled. This approach has resulted in scales such as the Attitudes Towards Disabled Persons Scale (Yuker, Block, & Younng, 1966) and the Interaction with Disabled Persons Scale (Gething, 1994) that ask questions about "disabled" people [sic Latin, In such manner; so; thus. A misspelled or incorrect word in a quotation followed by "[sic]" indicates that the error appeared in the original source. ] in general terms in an effort to generate and then measure attitudes of the test-taker. Moreover, these scales typically use the computation Computation is a general term for any type of information processing that can be represented mathematically. This includes phenomena ranging from simple calculations to human thinking. of "total scores" on these instruments. This practice has sometimes led researchers and practitioners to erroneously er·ro·ne·ous adj. Containing or derived from error; mistaken: erroneous conclusions. [Middle English, from Latin err assume that a single dimension can account for perceptions of an individual with a disability. An estimated 43 million individuals were covered by the Americans with Disabilities Act when it was originally introduced (Pierce, 1991). These 43 million individuals are not a homogenous homogenous - homogeneous group and perceptions of them are likely to vary as well. An individual's perception of a worker with a learning disability is likely to be quite different than their perception of someone with alcoholism alcoholism, disease characterized by impaired control over the consumption of alcoholic beverages. Alcoholism is a serious problem worldwide; in the United States the wide availability of alcoholic beverages makes alcohol the most accessible drug, and alcoholism is or epilepsy epilepsy, a chronic disorder of cerebral function characterized by periodic convulsive seizures. There are many conditions that have epileptic seizures. Sudden discharge of excess electrical activity, which can be either generalized (involving many areas of cells in . Although some perceptions toward individuals with disabilities may have a common factor, it is not likely the entire explanation. It seems more plausible that many interrelated in·ter·re·late tr. & intr.v. in·ter·re·lat·ed, in·ter·re·lat·ing, in·ter·re·lates To place in or come into mutual relationship. in factors determine an individual worker or employer's attitude toward a given individual with a disability. Cursory cur·so·ry adj. Performed with haste and scant attention to detail: a cursory glance at the headlines. [Late Latin curs evidence exists in the literature to support the idea that such underlying factors are important, and that, a single generalized gen·er·al·ized adj. 1. Involving an entire organ, as when an epileptic seizure involves all parts of the brain. 2. Not specifically adapted to a particular environment or function; not specialized. 3. attitude does not provide a complete or satisfactory explanation of perceptions of the person. Bordieri and Drehmer (1986) found that if a job applicant was personally responsible for their own disability that they were likely to receive lower evaluations from raters. Thus, one might expect two individuals with disabilities to be judged differently if one suffered their injury while driving under the influence while the other was disabled at birth. Another dimension thought to underlie perceptions is the disruptiveness of the disability. Stephens and Clark (1987) have found that people with visible disabilities are given more personal space than those with hidden disabilities. Despite the obvious conclusion that this might mean that those with visible disabilities suffer from lower evaluations, Bordieri and Drehmer (1986) found that hidden disabilities typically result in a greater negative impact in ratings. While the direction of bias remains debatable de·bat·a·ble adj. 1. Being such that formal argument or discussion is possible. 2. Open to dispute; questionable. 3. In dispute, as land or territory claimed by more than one country. , the fact remains that the disability's concealability may help determine the attitude of the rater rat·er n. 1. One that rates, especially one that establishes a rating. 2. One having an indicated rank or rating. Often used in combination: a third-rater; a first-rater. toward the individual. Another dimension that has received attention is the course of the disability (Stone, Stone, & Dipboye, 1992). This dimension is perhaps best characterized char·ac·ter·ize tr.v. character·ized, character·iz·ing, character·iz·es 1. To describe the qualities or peculiarities of: characterized the warden as ruthless. 2. as "closeness to death." There are both social and economic reasons why the course of the disability might bias ratings given by both supervisors and coworkers. Many other factors such as the unpredictability (Drehmer & Bordieri, 1985) and contagiousness con·ta·gious adj. 1. Of or relating to contagion. 2. Transmissible by direct or indirect contact; communicable: a contagious disease. 3. of the disability might also be added to the list of potential variables influencing perceptions of individuals with disabilities. These studies support the belief that not all disabilities are perceived equally and that more than a single factor may be necessary to explain individual attitudes toward people with disabilities. Only by fully understanding the various inter-related dimensions that lead to the formation of such biased attitudes, can unfair evaluations be eradicated. The current study was designed to test the hypothesis that attitudes toward persons with disabilities are not unidimensional. While some multidimensional mul·ti·di·men·sion·al adj. Of, relating to, or having several dimensions. mul ti·di·men scales exist, it is
important to note that simply factor analyzing existing scales would
provide only information concerning the dimensionality of those
particular scales, not necessarily the dimensionality of the construct
in question. This study attempts to generate a more appropriate
potential list of variables that might underlie perceptions of
individuals with disabilities.In order to accurately measure a person's propensity for bias it is important to include all of the relevant dimensions on which such bias may be based. More importantly, to understand how biased perceptions are formed we must go beyond the assumption that the perceptions of all individuals with disabilities are the same. The primary goal of the current research was thus to determine the number and characteristics of the dimensions underlying perceptions of workers with disabilities. A secondary goal was to determine if those underlying dimensions could then be used to predict criterion measures independent of disability-specific connotations (i.e. affect). Experiment 1 Method Participants. Eighty-seven undergraduate students at a major southern university completed the pilot study materials. All participants were recently employed and worked at least 20 hours a week. Approximately 57% of the sample was male and the majority of the sample was Caucasian (86%). The subjects were recruited through the university subject pool and received extra credit in psychology classes for their participation. Instruments. The materials described were developed specifically for the current pilot study and were administered to 50 of the 87 participants. These materials simply asked the subjects to list "all possible concerns" that they would have about certain individuals with disabilities in specific situations. Twelve scenarios were created based on manipulating two separate dimensions. The first dimension was whether the rater was a subordinate, coworker co·work·er or co-work·er n. One who works with another; a fellow worker. , first-line supervisor, or an employer. The second dimension concerned whether the disability itself was a physical disability, a mental disability, or a communicable disease communicable disease n. A disease that is transmitted through direct contact with an infected individual or indirectly through a vector. Also called contagious disease. . Again, by manipulating these two dimensions a total of twelve scenarios resulted. Procedures. The pilot study materials were designed to elicit e·lic·it tr.v. e·lic·it·ed, e·lic·it·ing, e·lic·its 1. a. To bring or draw out (something latent); educe. b.

The three various disability types were used in order to prevent participants from basing all of their answers on one particular disability exemplar ex·em·plar n. 1. One that is worthy of imitation; a model. See Synonyms at ideal. 2. One that is typical or representative; an example. 3. An ideal that serves as a pattern; an archetype. 4. . The participants were asked to take on different perspectives to provide the participant with an opportunity to express a wider range of possible concerns for a given disability type. The remaining thirty-seven students (in groups ranging from 2 to 4) were asked open-ended questions A closed-ended question is a form of question, which normally can be answered with a simple "yes/no" dichotomous question, a specific simple piece of information, or a selection from multiple choices (multiple-choice question), if one excludes such non-answer responses as dodging a in interview format. The questions were asked from a less professional/more personal perspective similar to a focus group. Subjects were asked questions such as "what do you think about an individual with a disability on your intramural intramural /in·tra·mu·ral/ (-mu´r'l) within the wall of an organ. in·tra·mu·ral adj. Occurring or situated within the walls of a cavity or organ. team or as a roommate." Once ideas were introduced by participants, the discussion was allowed to continue with minimal interference from the researcher. These discussions were later transformed into statements similar to those provided on the paper and pencil materials. Results and Discussion A rigorous quantitative analysis Quantitative Analysis A security analysis that uses financial information derived from company annual reports and income statements to evaluate an investment decision. Notes: of the data, from both of these exercises was not possible due to its open-ended nature.

Next, where possible, each statement was reduced to a one-word concern ("could I catch it" was reduced to contagiousness, etc.). Similar statements were grouped together under these one-word categories. While some judgment calls were required, the statements typically grouped quite naturally into categories. Thus, for each participant, a list of one word "concerns" resulted. As a check of the researcher's conceptualization con·cep·tu·al·ize v. con·cep·tu·al·ized, con·cep·tu·al·iz·ing, con·cep·tu·al·iz·es v.tr. To form a concept or concepts of, and especially to interpret in a conceptual way: , the participants who had engaged in the focus group activities (N-37) were also asked to take the original statements and group them under appropriate headings. While a few statements were inconsistently classified into categories, the majority of the statements (70%) were classified identically across all thirty-seven participants. Of the remaining 30% of the statements, all were associated with a particular category by at least half of the 37 participants. In general, the categorizing frameworks that the participants produced were remarkably similar to the researchers'. A total of sixteen concerns resulted from this exercise. The sixteen concerns and a brief description of each are presented in Table 1. Table 1 Sixteen Concerns Regarding Workers with Disabilities Aesthetics (Degree to which disability is physically unappealing) Causality (Degree to which disability was internally caused) Concealability (Degree to which disability can be hidden) Contagiousness (Degree to which disease/disability can be spread and if so the extent to which it can) Controllability (Through medication/therapy can disability be controlled) Curability (Degree to which disability is curable) Distractiveness (Degree to which disability is distracting to either coworkers, employers or clients in a way other than aesthetic) Preferential treatment (Degree to which if hired disabled person would receive preferential treatment/special privileges from workers/boss that might interfere with effective workflow) Need for assistance (Degree to which disability would necessitate structural accommodations) Novelty (How much is known about the disability?) Oversensitivity (Degree to which disabled person will be overly sensitive about condition) Peril (Degree to which death is likely in the near future) Response of disabled to stressful situation (Degree to which time dead-line crunch would effect person) Severity (Degree to which disability interferes with day to day activities) Stability (Degree to which disability is static in nature and course) Work Longevity (Degree to which disability will render the person unable to continue working in the near future) One way to determine the dimensions that affect people's attitudes or perceptions of the disabled would be to simply ask people what factors affect their feelings toward individuals with disabilities at work. This straight-forward approach is relatively common in the field of rehabilitation rehabilitation: see physical therapy. psychology. Unfortunately, such an approach suffers from several shortcomings A shortcoming is a character flaw. Shortcomings may also be:

One hundred and seventy-one introductory psychology students at a major southern university completed the study. Approximately 55% of the sample was male and the majority of the sample was Caucasian (82%). While this lack of diversity may be somewhat troublesome to some, in all likelihood, it mirrors the demographic make-up Make-up The amount of deficiency when a cash flow or capital item is deficient. For example, an interest make-up relates to the interest amount above a ceiling percentage. of the decision-makers at many large firms potentially employing individuals with disabilities. The participants in the current study were recruited through the university subject pool and received extra credit in psychology classes for their participation. As in the first experiment, a necessary condition of participation was current employment of at least 20 hours a week. Instruments. Two sets of materials were required for the policy capture. Set 1 materials asked participants to indicate the degree of association they felt existed between a person with one of 15 common disabilities and the 16 concerns that resulted from the pilot study. Participants were asked to make this rating on a Likert-type scale ranging from 1 (not associated) to 5 (highly associated). The 15 disabilities were chosen based on two general criteria. First, common disabilities that would be well-known by most participants were preferred over uncommon ones. Second, an effort was made to select a diversity of disabilities (i.e. physical, mental, and communicable diseases communicable diseases, illnesses caused by microorganisms and transmitted from an infected person or animal to another person or animal. Some diseases are passed on by direct or indirect contact with infected persons or with their excretions. ). The resulting disabilities that were used as stems in the current study were persons with alcoholism, amputee am·pu·tee n. A person who has had one or more limbs removed by amputation.

When both legs and arms are affected, the condition is called quadriplegia. , schizophrenia schizophrenia (skĭt'səfrē`nēə), group of severe mental disorders characterized by reality distortions resulting in unusual thought patterns and behaviors. , and tuberculosis tuberculosis (TB), contagious, wasting disease caused by any of several mycobacteria. The most common form of the disease is tuberculosis of the lungs (pulmonary consumption, or phthisis), but the intestines, bones and joints, the skin, and the genitourinary, . The Set 2 materials presented participants with various scenarios and asked subjects how each of 15 disabilities would affect (not likely to very likely) their perception of the individual with the disability. The criterion measures included many variables of interest to organizations. These measures were: (a) perceived effect on working relationship of the workgroup, (b) hiring decision, (c) promotability, (d) tardiness/absenteeism problem, (e) willingness to work with, (f) willingness to work for, (g) trainability, (h) work motivation, and (i) predicted productivity. Examples of both Set 1 and Set 2 materials are presented in Tables 2 and 3, respectively.

Traditionally, vignettes are presented to participants. In these vignettes the independent variables of interest are manipulated across the vignettes. As an example, one might manipulate the gender, race, and education level across the vignettes. Let us assume for now that we have two genders, four races, and that we use four levels of education. By manipulating those three variables we could produce 32 different vignettes (2 X 4 X 4). The participants are then asked to rate the individuals in each of the vignettes on some dependent variable. Then, by simply conducting a regression analysis In statistics, a mathematical method of modeling the relationships among three or more variables. It is used to predict the value of one variable given the values of the others. For example, a model might estimate sales based on age and gender. it is possible to determine how the participants used the different independent variables in forming a rating on the dependent variable. Thus, the participants are never explicitly asked about the independent variables. In the current study, however, forming vignettes that manipulated the 16 relevant concerns simply in terms of high versus low levels of each concern would have resulted in 65,536 vignettes ([2.sup.16]). Based on the impracticality im·prac·ti·cal adj. 1. Unwise to implement or maintain in practice: Refloating the sunken ship proved impractical because of the great expense. 2. of this task, a different approach was utilized. In the current study, vignettes were essentially replaced by the 15 specific disability exemplars. The participants' inherent disability-dimension associations tapped by the Set 1 materials thus served as the independent variable manipulation. The dependent variable was ascertained as·cer·tain tr.v. as·cer·tained, as·cer·tain·ing, as·cer·tains 1. To discover with certainty, as through examination or experimentation. See Synonyms at discover. 2. by having the participant complete the Set 2 materials. These materials captured the effect that each disability had on the various criterion measures. Thus, as with a traditional policy capture, the participants were never asked explicitly about the effect each of the dimensions had on any of the dependent variables. The two sets of materials were completed approximately one week apart to control for any memory effects. Results and Discussion One hundred and seventy-one students completed both sets of materials. The correlations among the 16 concerns are presented in Table 4. These correlations reflect the associations between the different concerns across all subjects (note that the correlations among the 16 concerns were appropriately pooled across the 15 disabilities). Thus, Table 4 presents the pooled within-disability correlations. As the table illustrates these correlations were high in some cases. In order to simplify the analysis and to provide insight into the underlying relationships among the 16 concerns, a factor analysis was conducted.

Although the Kaiser-Guttman criterion (eigenvalues eigenvalues statistical term meaning latent root. greater than unity) suggested a four-factor solution, an analysis of the scree plot and the parallel analysis criterion (Humphreys & Montanelli, 1975; Lautenschlager, 1989) both indicated a three-factor solution was more appropriate.

Factor 2 was labeled the risk factor and seems to represent the degree of risk or uncertainty associated with a disability. Factor 3 consisted of distractiveness, severity, response to stressful situation, oversensitivity, and preferential treatment. This factor was termed the response factor as it seemed to tap the person's response toward the environment. The three-factor solution accounted for 45.9% of the variance in the data set.

The next question addressed by the current study was whether or not these dimensions could be used to predict the nine criterion responses. Particularly important was the question of whether these dimensions could predict the criterion responses in lieu of Instead of; in place of; in substitution of. It does not mean in addition to. the specific disability in question. Based on the above factor analysis, factor scores were computed for each of the 171 subjects on the overtness, risk and response factors. These variables were then entered simultaneously as the first step of a hierarchical regression for each of the nine dependent variables. Next, the disability-specific components were forced into the hierarchical regressions (this was accomplished via dummy Sham; make-believe; pretended; imitation. Person who serves in place of another, or who serves until the proper person is named or available to take his place (e.g., dummy corporate directors; dummy owners of real estate). coding each disability as a within-subjects factor). This second step essentially reflects the value of knowing what specific disability was being rated above and beyond knowing a disability's perceived status on the three underlying dimensions (i.e. the disability-specific connotation con·no·ta·tion n. 1. The act or process of connoting. 2. a. An idea or meaning suggested by or associated with a word or thing: ). Finally, the 45 possible interaction effects (3 factors X 15 disabilities) were entered into the hierarchical regression simultaneously. This step would indicate if affect moderated the relationship between the three dimensions and the criterion measure. Table 6 presents the results for this analysis for all nine dependent variables.

The results from this analysis are fairly consistent across the nine dependent variables. Knowledge of the disability-dimension associations typically accounted for around 30% (ranging from 23% to 36%) of the variance and was significant in all cases. This is interpreted as evidence that these dimensions can be used to predict criterion responses effectively; however, column two in Table 6 shows that in all cases the disability-specific components added significant 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. (on average accounting for an additional 18% of variance). Thus, there was a benefit in knowing the connotation associated with a specific disability above and beyond what would be expected based only on the overtness, risk and response of that given disability. Finally, with only one exception, the interactions failed to significantly increase incremental variance. That is, for eight of the nine dependent variables it appears as though the dimensions were used similarly across disabilities (i.e. disability does not moderate the dimension-dependent variable relationships). The standardized standardized pertaining to data that have been submitted to standardization procedures. standardized morbidity rate see morbidity rate. standardized mortality rate see mortality rate. beta weights are thus presented for the nine dependent variables in Table 7. Obviously, those presented for hiring decision should be interpreted with caution since in that case the dimensions were moderated by the disability. General Discussion The primary purpose of this study was to determine the character of the dimensions underlying perceptions of individuals with disabilities. Both the Attitudes Towards Disabled Persons Scale (Yuker, Block, & Younng, 1966) and the Interaction with Disabled Persons Scale (Gething, 1994) compute To perform mathematical operations or general computer processing. For an explanation of "The 3 C's," or how the computer processes data, see computer. and interpret summated rating scores. These scales seem to imply that there is some degree of general affect toward those labeled as disabled and that by generating and measuring that affect one can capture the essence of "attitudes toward individuals with disabilities." A modified policy capturing technique was used in order to minimize the effects of social desirability. The resulting factor analysis found that at least three distinct dimensions underlie perceptions of individuals with disabilities, thus rejecting the unidimensionality hypothesis. Another important outcome of the current study involves the composition of the three dimensions found to underlie perceptions of individuals with disabilities. In particular, rehabilitation professionals may be interested in knowing what aspects of an individual with a disability are used by raters in forming attitudes. First, a dimension relating to relating to relate prep → concernant relating to relate prep → bezüglich +gen, mit Bezug auf +acc the overtness of the disability was found to be important in predicting eight of the nine outcomes (see Table 7). Factor 1 seems particularly important in any criterion measure involving personal contact with the individual with the disability. These dependent variables would include working relationships, eventual promotability, and the ability to benefit from training. Individuals with a highly visible disability should be advised accordingly. They may want to emphasize their social skills and provide evidence of their ability to get along with colleagues and supervisors.

The second dimension found to underlie perceptions of the individuals with disabilities was the risk associated with the disability. Risk was found to be predictive of all criteria except working relationship, hiring decision, and productivity. It is important for rehabilitation professionals and individuals with disabilities to realize that the level of risk associated with their given disability is an important consideration for raters. This fact may imply the need for better education of non-disabled colleagues on the contagiousness, stability, and course of a given individual with a disability. As an example, an HIV-positive worker may be well served to educate his/her colleagues on the remote chances of contracting HIV HIV (Human Immunodeficiency Virus), either of two closely related retroviruses that invade T-helper lymphocytes and are responsible for AIDS. There are two types of HIV: HIV-1 and HIV-2. HIV-1 is responsible for the vast majority of AIDS in the United States. through casual contact. To the degree that individuals with disabilities can minimize the assumed risk associated with their disability, one would expect the negative consequences of this factor to be reduced. The third dimension found to underlie perceptions of individuals with disabilities was a response dimension. This dimension appears to tap the disabled person's response to the environment. Unlike the other two dimensions, the response dimension was not prominent in previous literature. It is therefore somewhat surprising that this dimension appears to be the most important predictor of all nine dependent variables (note standardized beta weights in Table 7). This indicates that a major determinant determinant, a polynomial expression that is inherent in the entries of a square matrix. The size n of the square matrix, as determined from the number of entries in any row or column, is called the order of the determinant. in the formation of attitudes toward the individuals with disabilities concerns the disabled individual's response to their environment. Individuals with a disability may be well advised to refrain from displaying an overly large "sense of entitlement" during job interviews, etc. Finally, Table 6 demonstrates that the overtness, risk, and response dimensions do not tell the entire story. Some disabilities appear to have specific affect associated with them above and beyond the overtness, risk, and response associated with that disability. It is important to note that the affect measured in this study is associated with specific disabilities, not the "disabled" in general. It is also important to realize that, in most cases, the interactions between disability and the three dimensions were not significant. This indicates that even in cases where disability specific connotations exist, the dimensions underlying the disabilities are still used by the rater in the same fashion. That is, the dimensions are still predictive of attitudes without being moderated by the specific disability in question. Conclusions In summary, the current research has shown that several factors helped determine whether an individual was likely to suffer from biased perceptions. Attitudes toward individuals with disabilities were shown to be multidimensional in basis, and could not be adequately classified as unidimensional. The current research did not entertain lofty visions of changing people's social cognitions Social cognition is the study of how people process social information, especially its encoding, storage, retrieval, and application to social situations. Social cognition’s focus on information processing has many affinities with its sister discipline, cognitive psychology. or magically transforming the world into one free from all forms of bigotry Bigotry See also Anti-Semitism.

Instead, it was undertaken in an attempt to discover the basis of biased perceptions so that directed efforts could be undertaken to reduce such bias. The results of this study provide some guidance, in that, perceptions of individuals with disabilities seem to be dependent on the overtness, risk, and response associated with the disability. Before advising a client entering the workforce, a counselor should take into account the level of overtness, risk, and response associated with their client's specific disability. They should also carefully consider any disability-specific connotations associated with that particular disability.
