Psychometric Characteristics of a Vocational Preference Inventory Short Form

Abstract

This article presents reliability and validity evidence for Form B of Holland's Vocational Preference Inventory (VPI), a 42-item short form which was further reduced to 30 items for this study. The psychometric properties of this revised scale were assessed by using employees from five Federal Government organizations as respondents (N=2621). Factor analyses, interscale correlations, measures of internal consistency, and criterion group profiles are presented and discussed. All data, with some minor exceptions, support the utility of this form in research studies in which longer instrumentation cannot be used because of space or other limitations. In general, the evidence was supportive of both the construct (factorial) and criterion-related validity of the newly devised 30-item form of the VPI.
