Empirical evidence for the validity of the Job Crafting Scale (JCS) in a Portuguese setting

Abstract

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 ¼ 315 and n2 ¼ 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.
