The article describes the development and validation of the Career Personality Styles Inventory (CPSI). The CPSI comprehensively assesses Holland's career personality styles with only 22 items. Based on a series of 3 studies, we found satisfactory internal consistency, factor structure, and criterion validities of the newly constructed CPSI.

The study used the Self-Directed Search (SDS) and the NEO-FFI to explore profile elevation, four secondary constructs, and the Big Five personality factors in a sample of college students in a career course. Regression model results showed that openness, conscientiousness, differentiation high-low, differentiation Iachan, and consistency accounted…

Seventy-five male and 77 female college students completed the Personality Adjective Check List and Self-Directed Search. Results show that Millon's personality styles and Holland's occupational types are reliably linked, seeming closest in the concept of social dominance-submission and emotionality-restraint and most divergent in the view of…

Tested whether scores on the Self Directed Search relate to career development needs in a study of 138 college students. Findings showed the scores related differentially in ways predicted by Holland (1973) and supported probing whether college students earning low investigative scores were behind in their career development.

Examination of two-letter high-point code frequency tables of four Self-Directed Search samples and Holland's translation of occupational titles verified the fit of the circumplex model, supporting Holland's person-environment hypothesis. (SK)

Examined race and sex differences in personality profile among nursing students. The Self Directed Search was administered to students entering baccalaureate nursing programs. Results generally supported Holland's typology. Race and sex differences in SDS codes were not significant. Some differences were found in socioeconomic characteristics.…

Self Directed Search (SDS) and Vocational Preference Inventory (VPI) results occupations and fields of study were organized to show the distributions of personalities within an occupation or field of study. The results show that single fields tolerate several types, but some types occur only infrequently. (Author)

Examined relationship between membership in adolescent social crowds and vocational identity in early adulthood. In four samples (N=274), membership in five junior high school crowds (Motorheads, Brains, Freaks, Politicos, Conformists) was associated with higher scores on Realistic, Investigative, Artistic, Enterprising, and Conventional scales,…

Explored Holland's congruency construct and effect of sex and race on Self-Directed Search response patterns in 29 black and 31 white undergraduates or postgraduate students enrolled in a Medical Education Preparatory Program. Results clearly support congruency of sample's code with the criterion code of Holland's sample, providing support for…

Investigates beginning college students' willingness to volunteer in a variety of campus organizations. Researchers analyzed the effect of such factors as compensation, personality types, and gender differences on volunteer willingness. Although compensation seemed unimportant for volunteering, results indicated correlations between volunteering…
