Empirical evidence for the validity of the job crafting scale (JCS) in a Portuguese setting Evidencia empírica de la validez de la job crafting scale (JCS) en una muestra de trabajadores Portugueses Evidência empírica de validade da versão Portuguesa da job crafting scale (JCS)

Purpose: This study aims to adapt and validate the Job Crafting Scale (JCS), a measure based on the conceptualization of job crafting of the job demands–resources theory, for a sample of Portuguese workers and to test its psychometric properties regarding validity (factor, convergent, discriminant, and criterion) and reliability. Design/methodology/approach: Two subsamples (n1 = 315 and n2 = 329) of Portuguese workers aged 18 years old and over participated in this research. Exploratory factor analysis and confirmatory factor analysis were used to assess the factor structure. Findings: The results indicated that the Portuguese version of the JCS, with 18 items, has a factor structure composed of four-correlated factors. Furthermore, the results demonstrated the existence of factor, discriminant, and criterion validity, as well as reliability. Originality/value: This study provides a job crafting measure adapted to the Portuguese language that can serve as a diagnostic tool for workers and organizations.
