Development and Validation of the Vocational Identity Measure

Abstract

Having a strong vocational identity is a prelude to the formation of individuals’ overall identity. Hence, vocational identity has long been a variable of interest in vocational research. However, most existing studies utilized Holland, Gottfredson, and Power’s My Vocational Situation (MVS) vocational identity subscale to measure vocational identity. Due to how its items are worded, we contend that the MVS was not able to accurately capture vocational identity as a stable construct. Its dichotomous response scale also limits researchers’ attempts to evaluate its psychometric properties. To address these issues, we developed and validated a new “Vocational Identity Measure (VIM)” that utilizes Likert-type responses. The VIM seeks to measure how aware individuals are of their stable career goals, interests, and abilities. Results (Studies 1 and 2) suggest that the VIM possesses sound internal reliability, a stable single-factor structure, and incremental validity over the MVS. The scale also has good convergent validities with relevant constructs such as career decision self-efficacy and exploration. Based on these findings, the strengths and limitations of the VIM scale are discussed, and future research directions are proposed.
