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)

This study was designed to investigate the differential effectiveness of Holland's Self Directed Search (SDS) as a vocational guidance tool for 166 junior-class students in a suburban regional high school. Congruence scores were developed for each student and were then compared to four variables. Results are discussed. (Author/EJT)

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)

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.

This study, using the Vocational Preference Inventory and the Self-Directed Search, explored the concurrent validity of Holland's theory for employed college-degreed Black women. The findings support the validity of Holland's theory for this population. (Author)

The study was designed to explore two areas: (1) the concurrent validity of Holland's theory for employed college degreed women using two different operational definitions (Vocational Preference Inventory and the Self-Directed Search) of vocational orientation; and (2) the relationships among same named scales across the VPI and the SDS. (Author)

Proposes a measure to evaluate the agreement between Holland's Self-Directed Search (SDS) and occupational preference with students (N=42) seeking vocational guidance. Results showed that the proposed index of agreement is applicable to the SDS and to any situation where ranked (ordinal) data is partially recorded. (LLL)

The scales of the Self-Directed Search (SDS) were correlated with the scales of the Armed Forces Vocational Aptitude Battery (ASVAB) for a sample of 192 high school girls. The two devices have small to moderate correlations that indicate self-reported abilities and competencies have some concurrent validity. (Author)

The Vocational Preference Inventory (VPI) and the Self-Directed Search (SDS) were administered to 102 Black women workers in occupational environments consistent with Holland's six vocational environments. Four scales in each test successfully differentiated the occupational groups, supporting the concurrent validity of Holland's theory for…

Examined the concurrent validity of Holland's theory for men and women employed in an enterprising occupation as well as the degree of personality-environment correspondence and relationships of personality type to job satisfaction. Findings suggested that within an employed sample, Holland's theory is valid for women as well as for men. (Author)

Tests Holland's assertion that stability of vocational choice can be predicted from: (a) congruence of personality with chosen career; (b) differentiation of personality; and (c) internal consistency of personality characteristics. The relationship of three constructs to stability of choice of college major was studied among 167 university…

High school males (N=66) and 60 high school females were tested for anxiety and vocational maturity levels. The experimental subjects were given the Self Directed Search (SDS). Statistical analysis indicated that the SDS was an effective instrument in reducing career indecision. (Author)

The author reviews the evidence for the beneficial effects of the Self-Directed Search (SDS), indicates that Hanson and Prediger have misinterpreted the theory, that their evidence is misleading, and that other evidence indicates that males and females of the same type are similar. The virtues of raw scores are summarized. (Author)
