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 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.

An investigation of the relationships and underlying constructs between expressed and inventoried interests across the occupational classification scheme of Holland, Roe and Strong was undertaken. The canonical factor structures that were calculated indicated two similar bipolar structures underlying the occupational schema studied. (Author)

The relationship was studied between the set of constructs specified by Holland's (1973) theory (viz, Realistic, Intellectual, Artistic, Social, Enterprising, and Conventional) measured by an Adjective List (AL) derived from Holland's theory and the same set of constructs as measured by the Vocational Preference Inventory (VPI).
