 with Disabilities

Several issues have been raised in the rehabilitation process with minority individuals, regarding the appropriateness of traditional psychological assessment instruments. Potential cultural bias in psychometric psy·cho·met·rics  
n. (used with a sing. verb)
The branch of psychology that deals with the design, administration, and interpretation of quantitative tests for the measurement of psychological variables such as intelligence, aptitude, and
 approaches to evaluation have been reported, but often with conflicting results. Organist (1982) outlined several key variables most significant in relation to the rehabilitation assessment process: (1) Situational/Personality variables, (2) Language differences, and, (3) Time perception. These variables may bias the evaluation process in either a positive or negative direction and thereby produce undesirable consequences. Thus, there is a need for valid assessment procedures where the influence of cultural factors is minimized, and thereby, those sources of measurement error which invalidate the assessment process eliminated. Research on psychometric approaches, particularly those related to measurement of cognitive-intellectual functioning of Mexican Americans, have been equivocal in their results. Both the Wechsler scales and the Peabody Picture Vocabulary test The PPVT-III is an untimed, individual intelligence test, orally administered in 11 to 12 minutes or less. Extensively revised, this test measures an individual's receptive (hearing) vocabulary for Standard American English.  have been studied, with reports of good reliability, but questionable validity (Budoff, Corman & Gimon, 1976; Goldman & Hartig, 1975; Henderson & Rankin, 1973; Henggeler & Tavormina, 1979; Reiber & Womack, 1968; Simon & Joiner join·er

The official language of Spain and 19 Latin American nations, Spanish is spoken as a first language by about 330 million persons  use or Spanish surname as their primary cultural descriptors. While useful, these descriptors do not include other cultural factors of potential significance in measurement. Current theorists have clearly identified a number of additional acculturation variables and have developed procedures to assess them (Cuellar, Harris & Jasso, 1980; Padilla, 1980; Szapocznik & Kurtines, 1980).

Cuellar and Arnold (1988) and Rivera (1983) indicated the importance of evaluating level of acculturation in an attempt to provide a basic understanding of the client's cultural background, and thus reducing potential biases in psychometric evaluation through formal, clinically moderated approach to interpreting data.

The present study attempted to identify the relationship between certain cultural factors and assessment of rehabilitation potential in a Mexican American sample of individuals with disability.

, acculturation, and the four factor components of acculturation: (1) language preference, (2) ethnic identity and generation, (3) ethnicity of friends and associates, and (4) reading and written language and direct contact with Mexico. Background data was collected through a bilingual data sheet developed by the authors.

The major independent variable, level of acculturation, was documented by the Acculturation Scale for Mexican Americans (Cuellar et al., 1980).

) as described by McCarron and Dial (1976) and cross validated by Packard, Henke, and McCollum (1976) was utilized to measure the subject's level of vocational potential (McCarron & Dial, 1976). The dependent variables for the present study were the specific McCarron-Dial predictor measures. The MDES consists of four predictor measures that are grouped into three factors: (1) verbal-cognitive; (2) sensory; and (3) motor. Each of these factors are important in the assessment of behaviors that determine work potential or effective performance in a work environment. Additionally, the study included measures of adaptive behavior Adaptive behavior is a type of behavior that is used to adapt to another type of behavior or situation. This is often characterized by a kind of behavior that allows an individual to substitute an unconstructive or disruptive behavior to something more constructive. , and information processing information processing: see data processing.

. These latter measures have been recently developed for use in vocational assessment, as part of the total McCarron-Dial Evaluation System. The specific factors and measures used in predicting vocational potential were:

1. Verbal cognitive/information processing: Peabody Picture Vocabulary Test-Revised (L. Dunn & L. M. Dunn, 1981), and the Perceptual Memory Task (McCarron, 1984). The Peabody Picture Vocabulary Test (PPVT PPVT Peabody Picture Vocabulary Test ) is designed to measure an individual's verbal intelligence Noun 1. verbal intelligence - intelligence in the use and comprehension of language
intelligence - the ability to comprehend; to understand and profit from experience
 through the client's ability to associate a vocalized word, usually a noun or verb with a pictorial representation of the word. Each subject's verbal IQ or standard score was integrated into the McCarron-Dial Evaluation System (MDES). The Perceptual Memory Task (PMT See photomultiplier tube. ) was developed as a standardized method of assessing information processing skills and individual learning style. Since vocational evaluation attempts to systematically describe an individual's functional capacities, the PMT can be an integral part of vocational assessment. The PMT involves measures of spatial relations, visual recognition and visual sequential memory, long term recall and verbally mediated visual memory skills. The PMT's plan was to design a task involving cognitive problem solving problem solving

 strategies. The PMT can be utilized with a wide range of individuals with various cultural backgrounds since instructions to the tasks are simple do not require a verbal response, and require only receptive comprehension of colors which are orally named by the examiner. The total PMT score consists of the sum of all four subtest areas, converted to one standard score. Additionally, performance on the PMT has been shown to be significantly correlated with intellectual functioning on the Wechsler scale and PPVT

 and visual discrimination processes. The HVDT is organized to provide discrimination measures in four areas: size, shape, texture, and configuration. The HVDT requires subjects to manipulate geometrically shaped objects which are hidden from the visual field. The subject then attempts to identify the correct representation of the object on a chart. Each subject's number of correct responses in each of the four areas is incorporated into the MDES.

The Bender Visual Motor Gestalt Test developed by Lauretta Bender Lauretta Bender, M.D. (1897–1987) was a child neuropsychiatrist, best known as the creator of the Bender-Gestalt Test.

Her father was an attorney. She repeated first grade 3 times; she was thought to be mentally retarded because she reversed letters in reading and
 (1938) was designed as a test of visual-motor integration. The test consists of nine cards with abstract designs. Clients are asked to reproduce each design one at a time on a blank sheet of paper. Reproduction of the designs are influenced by integration of perceptual and motor processes. The Koppitz error system is used to score each design (Koppitz, 1975). The error score is converted to a standard score.

3. Motor functioning: McCarron Assessment of Neuromuscular neuromuscular /neu·ro·mus·cu·lar/ (-mus´ku-ler) pertaining to nerves and muscles, or to the relationship between them.

 Development (McCarron, 1975). The McCarron Assessment of Neuromuscular Development (MAND) provides a measure of a subject's fine, gross, and total motor abilities. Assessment of fine motor abilities is determined by five tasks, (1) beads in box, (2) beads on rod, (3) finger tapping, (4) nut and bolt Noun 1. nut and bolt - a fastener made by screwing a nut onto a threaded bolt

, (5) rod slide. Assessment of gross motor abilities are measured by (1) hand strength, (2) finger-nose-finger, (3) jumping, (4) heel-toe tandem walk, and (5) standing on one foot. The MAND can also be used to determine bimanual bimanual /bi·man·u·al/ (bi-man´u-al) with both hands; performed by both hands.

 dexterity, persistent control, muscle power and balance-kinesthetic control. Three standard scores are derived from the MAND corresponding to the fine, gross and total motor abilities.

4. Integration-Coping (adaptive behavior): Street Survival Skills Questionnaire (Linkenholder & McCarron, 1980).

In order to get a better picture of functional strengths and weaknesses of Mexican Americans being evaluated, it has been suggested that both measures of intellectual functioning and adaptive functioning adaptive functioning,
n the relative ability of a person to effectively interact with society on all levels and care for one's self; affected by one's willingness to practice skills and pursue opportunities for improvement on all levels.
 be conducted (Mercer, 1976). A split half version of the Street Survival Skills Questionnaire (SSSQ) was utilized since the instrument has relatively high internal consistency. The shortened version thereby provided greater efficiency for data collection purposes. The SSSQ was constructed as a comprehensive measure of community relevant adaptive skills. It provides an objective measure of specific aspects of adaptive behavior.

The SSSQ consists of nine subtests, each measuring nine content areas most relevant to adaptive behavior. The nine areas are: (1) Basic Concepts, (2) Functional Signs, (3) Tool Identification, (4) Domestic Management, (5) Health, First Aid and Safety, (6) Public Services Public services is a term usually used to mean services provided by government to its citizens, either directly (through the public sector) or by financing private provision of services. , (7) Time, (8) Money, and (9) Measurement. The sum of all nine subtest scores are converted to one standard score.

Procedure

Each subject signed a bilingual agreement to participate along with a release of confidential information. Each subject was scheduled for an individual appointment at which a bilingual research assistant then administered (a) the Acculturation Rating Scale for Mexican Americans (Cuellar et al., 1980), (b) a background data sheet developed by the authors, and, (c) the abbreviated McCarron-Dial Vocational Evaluation Battery (McCarron & Dial, 1976). Each instrument was administered in English. Time of administration averaged 3.5 to 4 hours per subject.

Results

All dependent variable measures were converted to standard scores. Multiple correlation Noun 1. multiple correlation - a statistical technique that predicts values of one variable on the basis of two or more other variables
multiple regression
 analysis was used to examine the relationship between overall level of acculturation, the four acculturation factors, and each of the abbreviated McCarron-Dial factors contributing to prediction of vocational potential (Table 1).

Cognitive-Information Processing

Neither the PPVT nor the PMT showed a significant relationship to overall level of acculturation in this homogeneous bilingual, heterogeneous bicultural sample. However, in looking at the two measures of cognitive information processing, a stronger relationship with level of acculturation was noted for the Peabody than for the PMT. The strength of this relationship is accounted for in part, when one focuses on the specific cultural factor of ethnic identity and generation removed from Mexico. The relationship between this factor and performance on the PPVT was significant at the .05 level. The specific items contributing to a rating on this factor include: (1) "How do you identify yourself?", (2) "Which ethnic identification does (did) your mother use?", (3) "Which ethnic identification does (did) your father use?", (4) "Where were you (your parents, grandparents grandparents nplabuelos mpl

grandparents grand nplgrands-parents mpl

grandparents grand npl
) born?", (5) "How much ethnic pride do you have?", and (6) "How would you rate yourself (along a Mexicanized-Anglicized dimension)?".

Sensory

In the area of sensory functioning the Bender provided a correlation coefficient Correlation Coefficient

A measure that determines the degree to which two variable's movements are associated.

The correlation coefficient is calculated as:
 with acculturation approaching zero. Additionally, in the area of visual tactile functioning, the Haptic Visual Discrimination Test also showed no significant relationship with overall level of acculturation.

Motor Functioning

In the area of motor functioning, the McCarron Assessment of Neuromuscular Development had been administered resulting in summary scores for fine motor functioning, gross motor functioning, and overall total motor functioning. No significant relationships were found between motor functioning and level of acculturation in any of these areas.

Adaptive Behavior

In the area of adaptive behavior functioning, the Street Survival Questionnaire Survival Quotient (SQ) showed a significant correlation with overall level of acculturation. However, as with other components of this modified evaluation, each factor contributing to level of acculturation was also analyzed to identify the possibility of more subtle influences. On the SSSQ, factor 3 of the Acculturation Rating Scale for Mexican Americans, the factor measuring ethnicity of friends and associates correlated with the overall Survival Quotient. In order to understand which area of adaptive functioning might be contributing to this significant relationship, a correlation matrix Noun 1. correlation matrix - a matrix giving the correlations between all pairs of data sets
statistics - a branch of applied mathematics concerned with the collection and interpretation of quantitative data and the use of probability theory to estimate population
 with the nine tests of the Street Survival Questionnaire was constructed relating them to the overall level of acculturation and its four factor components (Table 2).

When this matrix was constructed, the subtest measuring knowledge of public services was significantly related to factor 4 (generation), and overall level of acculturation at the .05 level. Additionally, the test measuring knowledge of health and safety correlated significantly to factor 2 (ethnic identity). Neither of these two SSSQ tests was significantly correlated with education or socioeconomic status in a subsequent multiple correlation analysis.

Discussion

Results of this study suggest that the modified McCarron-Dial System represents an approach to evaluation of bilingual, bicultural Mexican-Americans which does not appear to be significantly affected by cultural factors in the areas of sensory and motor functioning. By implication, this also suggests, but does not validate, that the predictive nature of the measures would be essentially the same for bilingual Mexican Americans as it is for monolingual English-speaking Mexican Americans and Anglo Americans. Additional research is needed to determine if this inference is valid. Results also suggest no cultural influence on SSSQ adaptive behavior subscales measuring Basic Concepts, Functional Signs, Tools, Domestics, Time, Monetary, and Measurements.

Results also suggest that significant cultural bias may exist on the SSSQ in the areas of Health and Safety, and Public Services, producing a low score. A low score may reflect less knowledge than is actually the case. Adaptive behavior in the area of health and safety may be culturally different and not adequately measured by this subtest. Lower acculturation level may in fact be associated with less knowledge of "majority" culture adaptive behavior in these two areas. Studies have shown low levels of acculturation to be associated with the use of alternative, nontraditional, folk-related health care practices (University of Texas, 1979, chap.3). Another more recent study relates to the underutilization of health care, and possibly other public service agencies by less acculturated Mexican Americans. Underutilization may be due to a low knowledge of public services (Wells, Hough n. 1. Same as Hock, a joint.

, Golding, Burnam & Karno, 1987).

In the area of information processing, the PMT appeared to be less correlated with overall level of acculturation, and clinically, therefore, may be a better indicator of cognitive information processing abilities, as acculturation level decreases, than the PPVT. More subtle influences than language dominance may be interacting to provide less than accurate data on cognitive-intellectual functioning of bicultural clients (Hickey, 1972). Inferentially, this also suggests that as the client population moves to a more dominant Spanish language preference, a test such as the PMT which de-emphasizes language and its nuances will maintain its relevance as a measure of information processing. Whereas, a language and culturally dominant instrument such as the PPVT-R PPVT-R Peabody Picture Vocabulary Test-Revised , no longer validly measures cognitive functioning, but rather reflects acculturation level or English language comprehension, at best.

Systematic research is needed to identify and clarify the relationship between cultural factors and client performance on psychometric approaches to evaluation used with Mexican Americans. This research is needed on all existing instruments, and particularly those which have been translated for use with monolingual Spanish-speaking clients.

In conclusion, results of the present study suggest that evaluators need to assess the acculturation level of Mexican American clients. Mexican Americans rated in the bicultural to monocultural (Mexican) range on the acculturation scale should perhaps be administered secondary measures of cognitive-intellectual functioning (in addition to traditional IQ measures). These secondary measures should include performance requirements de-emphasizing language and sociocultural so·ci·o·cul·tur·al
