Job search quality is important for unemployed individuals pursuing reemployment. To comprehensively measure job search quality, we develop and test a 20-item Job Search Quality Scale (JSQS), using four samples of unemployed individuals (pilot sample, N=218; exploration sample, N=3372; confirmation sample, N=3372; and replication sample, N=434). Results show a four-dimensional structure, composed of (a) goal establishment and planning, (b) preparation and alignment, (c) emotion regulation and persistence, and (d) learning and improvement. Substantial evidence was found for its reliability, convergent and discriminant validity. Building job search quality’s nomological net, conscientiousness, learning goal orientation, self-efficacy, employment commitment, autonomous job search motivation, and social support emerged as positive correlates. Supporting its criterion-related validity, the JSQS predicted key job search and employment outcomes. Moreover, usefulness analyses supported its incremental validity beyond extant job search measures. Our findings have important implications for studying and measuring job search quality in future research and career counseling practice.
