Abstract. This research redefined the job demands–resources (JD-R) job crafting model ( Tims & Bakker, 2010 ) to resolve theoretical and empirical inconsistencies regarding the crafting of job demands and developed a German version of the Job Crafting Scale (JCS; Tims, Bakker, & Derks, 2012 ) in two separate studies (total N = 512). In Study 1 the German version of the JCS was developed and tested for its factor structure, reliability, and construct validity. Study 2 dealt with the validity of our redefined JD-R job crafting model. The results show that, like the original version, the German version comprises four job crafting types, and the German version of the JCS is a valid and reliable generic measure that can be used for future research with German-speaking samples. Evidence for the redefined JD-R job crafting model was based on findings relating job crafting to work engagement and emotional exhaustion.
