The authors empirically examine the effectiveness of an intervention program designed to facilitate interest in cyber science among high school students (N = 60). Pretest-posttest and mediation designs were used to model self-report data that were collected at pre-camp, during a cyber-related task at mid-camp, and at post-camp. An analysis of…

This article celebrates the 50th anniversary of the introduction of John L. Holland's (1959) theory of vocational personalities and work environments by describing the theory's development and evolution, its instrumentation, and its current status. Hallmarks of Holland's theory are its empirical testability and its user-friendliness. By…

Findings suggest that a woman will obtain a different Holland code depending on what instrument or what set of scales within an instrument is used to establish that code. This phenomenon could reflect sample characteristics equally as much as any bias in the measures. (Author)

The Realistic scale of the Vocational Preference Inventory (VPI) and the Realistic and Social scales of the Self Directed Search successfully differentiated the occupational groups. However, the VPI Social and Enterprising scales did not differentiate between men and women in the same occupation. (Author)

Investigated differences between Black and White women employed in traditional male occupations who took the Vocational Preference Inventory (VPI) and the Self-Directed Search (SDS). Findings indicate that White women when compared to Black women in the same occupation tend to report similar mean raw scores. (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…

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)
