Development and evaluation of a short RIASEC interest inventory

Abstract

This study set out to develop a short interest inventory based on Holland’s model of vocational personality types using items from the South African Career Interest Inventory (SACII). In study 1, we used 1000 responses to the SACII from an existing database to select 30 items for this interest inventory. Satisfactory reliability and structural validity were found for responses to these items. In study 2, we investigated the psychometric properties of these items on a sample of 183 participants. Satisfactory reliability and structural validity were again found. Implications and recommendations for research are discussed.
