Investigated occupational level differences among men and women employed in Enterprising environments using the Vocational Preference Inventory (VPI) and the Self Directed Search (SDS). All workers (N=84) were employed in Enterprising environments. Findings showed high occupational level workers tend to be more differentiated and more masculine…

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.

The Vocational Preference Inventory (VPI) and the Sixteen Personality Factors Questionnaire (16PF) were administered to 425 undergraduate students and compared using canonical analysis. The contributions of the scales of the VPI and the 16PF to the three relationships supported Hollans's theory of vocational choice, the use of the VPI for…

The hypothesis that the VPI and WVI are measuring the same domain based on theoretical similarities was tested using 195 male freshperson students. The data were analyzed by correlational technique including discriminant analysis. The results allow for the interpretation that the VPI and WVI are in fact measuring two distinctive domains.

This article describes an attempt to differntiate Holland's six types by means of personality need variables. Participants were administered Holland's VPI and Jackson's Personality Research Form (PRF). One-way analyses of variance revealed that PRF variables could not differentiate Holland's six types.
