A sample of male Investigative subjects (N=171) who completed the SDS as freshmen in 1970 was sent a questionnaire four years later. Results indicated that, for Investigative-type freshman males, the SDS has moderately high efficiency in predicting, four years later, their ultimate major and their immediate and future vocational plans.

Two Minnesota Importance Questionnaire (MIQ) scales, Creativity and Independence were validated by experiment. Subjects (N=68) were exposed to four task conditions representing joint combinations of high or low levels of Creativity and Independence. The behavioral results were consistent with the subjects' MIQ score levels on the two scales,…

A scoreable biographical data key was developed for a group of women lower level managers, and applied to male and female managers. Showed statistical validity for both the cross-validation sample and for the samples of female and male managers. (Author)

To find evidence of generalizability of four interest factors established for tests within the Roe-Holland framework, factor scores derived from a Vocational Interest Inventory grounded in Roe's system were correlated with Strong-Campbell Occupational scale scores. For this sample of 300 counseling clients, a majority of the hypothesized relations…

A behaviorally specific motivational effort rating scale was developed and tested. The organizational specific scale results were examined and compared to those generated from the Landy and Guion scale. It was found that the organizationally specific and engineer relevant scale is a better predictor of two types of expectancies. (Author)

The authors investigated the concurrent validity of Holland's theory for employed non-college-degreed men using two inventories of vocational orientation. The results revealed that two scales of one and four scales of the other inventory successfully differentiated the occupational groups consistant with Holland's theoretical framework. (Author/SE)

This study, using the Vocational Preference Inventory (VPI) and the Self-Directed Search (SDS), explored concurrent validity of Holland's theory for employed non-college-degreed women (N=114). Results revealed three scales of the VPI and five scales of the SDS successfully differentiated occupational groups consistent with Holland's theoretical…

Results showed strong empirical support for the model in that most subjects were working in environments congruent with their personality types. However, there was a lack of empirical support for the proposed relatedness among the environments in the model with regard to person-environment congruence. (Author)

The purpose of this study was to investigate the usefulness of the Career Maturity Inventory (CMI) as a measure of vocational maturity. The findings indicate that scores on the CMI incrementally increase by grade level. However, the rate and level of this increase is influenced by sex, school, and curriculum effects. (Author)

The study was designed to explore the concurrent validity of Holland's theory for employed non-college degree black men. Concurrent validity was studied by administering the Vocational Preference Inventory (VPI) and the Self Directed Search (SDS) to workers. Results tend to suggest that Holland's theory is meaningful for employed non-college…

The study evaluates a test of occupational information administered to a national sample of 5000 young men in 1966, as part of the National Longitudinal Surveys of employment behavior. The measurement instrument is judged to exhibit desirable characteristics in terms of internal consistency reliability, discriminatory power, and level of…

Self Directed Search (SDS) raw score and same-sex normed standard score codes were obtained on a sample of 16- to 18-year-old New Zealand high school students. The 59 boys and 59 girls who showed differences in the first letter of their codes rated the attractiveness of selected DOT job descriptions. (Author)

Studies the application of the monotonic criterion, i.e., career development proceeds in a continuous pattern. Systematic increases in scores on the Career Development Inventory are shown by high school students, but not by college students. Findings and related theory support discontinuity of career development process after high school. (DOW)

A Hebrew interest inventory for females in Israel, based on Holland's vocational classification, was examined on 322 female pupils and 167 working females. Results showed subjects occupied in a field had highest interest scores in that field and the highest interest score was the score of those engaged in that field. (Author)

A test of the personality constructs hypothesized by Holland was performed using a list of adjectives believed to be descriptive of the respective types. The sample used the adjectives to describe themselves in a manner consistent with Holland's model, however the correspondence was closer for males than females. (Author)
