Intra-Profile Relationships for Key Psychometric Variables in Occupational Evaluation.
Cook, Robin A.
Among the constructs commonly considered by career counselors are vocational interests, aptitudes, and personality variables. Although the predictive power of each of these domains with respect to successful occupational functioning has been demonstrated, little research has been conducted on the nature of their interaction. The interrelatedness of vocational interests, aptitudes, and personality traits was evaluated using a modified version of the Inter-Domain model postulated by Lowman (1991, 1993). Participants were 101 people aged 16 or over who were enrolled in state employment and training programs. These subjects were given a battery of four standardized psychometric instruments: (1) Sixteen Personality Factor Questionnaire, Fifth Edition (R. Cattell, H. Eber, and M. Tatsuoka, 1970); (2) Edwards Personal Preference Schedule (A. Edwards, 1959); (3) Self-Directed Search, Fourth Education (J. Holland, 1985); and (4) General Aptitude Test Battery (U.S. Department of Labor, 1982). Together these measured each of the three dimensions. Descriptive and discriminant analyses offered partial support for postulated construct relationships. Prediction of vocational interest category by personality, aptitude, and demographic variables was possible for some of the Holland categories. Implications for testing practices for youth and adults in secondary or postsecondary educational settings are noted. (Contains 6 tables and 51 references.) (SLD)
