Assessing Vocational Competency of People with Serious Mental Illness through Self-Report: A Brief Clinical Measure
Self-determination theory (SDT) can be used as a framework to assess self-determined work motivation and vocational recovery in people with serious mental illness (SMI). Vocational competency is a key SDT construct associated with self-determined motivation, rehabilitation engagement, and vocational recovery. The purpose of this study was to validate a brief vocational competency measure, the LSI-Vocational Competency Scale (LSI-VCS), which was adapted and abbreviated from the Life Skills Inventory (LSI), for people with SMI. Results confirmed a two-factor measurement structure and the two factors were labeled as job performance self-efficacy and job seeking self-efficacy. Both factors demonstrated acceptable levels of internal consistency reliability and correlated with other SDT vocational constructs in the expected directions. The LSI-VCS is a brief and psychometrically sound self-report measure that can be used to assess vocational competency of people with SMI in psychiatric rehabilitation research and practice.
