We present the conceptualization and validation of the Needs-Based Job Crafting Scale (NJCS), a new assessment tool theoretically grounded in the Identity-Based Integrative Needs Model of Crafting and DRAMMA psychological needs (detachment, relaxation, autonomy, mastery, meaning, and affiliation). The article is composed of three studies. In Study 1, we develop the NJCS and test its factorial structure using a cross-sectional sample of Finnish employees (N = 578). In Study 2, we validate the factor structure and test the scale for measurement invariance across time with longitudinal samples from Finland (N = 578) and Japan (N = 228). In Study 3, we examine the convergent, criterion, and incremental validity using a sample of German and Swiss employees (N = 1,101). The results confirm a six-factor structure of the scale as defined by the detachment, relaxation, autonomy, mastery, meaning, and affiliation needs in all three samples. The NJCS showed convergent validity when correlated with the conceptually related Needs-Based Off-Job Crafting Scale (NOCS), a job crafting scale based on the job demands–resources (JD-R) model, and the Proactive Personality Scale. Further, the six job crafting dimensions explain a large amount of variance in work engagement, job satisfaction, burnout, and psychological needs satisfaction; thus, supporting criterion validity of the scale. Finally, the NJCS explains variance beyond the existing JD-R based job crafting scale in work engagement, job satisfaction, burnout, and recovery experiences; thus, supporting incremental validity of the NJCS. Together with the existing NOCS, the NJCS facilitates the examination of crafting dynamics within and across work and nonwork life domains, applying a shared theoretical framework of psychological needs.
