The aim of the current study was to validate the Serbian adaptation of the Job Crafting Scale (JCS), applying both qualitative and quantitative approaches, within three studies totalling 832 employees from different industries. Job crafting is work behaviour aimed at modifying job tasks in order to enhance and maintain work motivation. In Study 1, we have tested the understanding of all items and their possible cultural embeddedness. In Study 2, we have tested the JCS factor structure, factors' reliability and validity. In Study 3, we have tested the invariance of the proposed models (Study 2 and Study 3 models) and criterion validity by analysing the correlation between the JCS and work engagement. Qualitative analysis has revealed that the majority of items transferred the intended meaning. Special care should be taken in interpreting the decreasing hindering job demands dimension scores, since these items might point toward behaviours that were not perceived as positive. With its overall reliability, second-order four-factor model invariance and criterion validity, originally composed 21-item JCS could be considered to be a valid instrument for assessing job crafting in Serbia. The present study has also shown that the 12-item JCS-Serbian short version has satisfactory psychometric properties and that it could be considered as a valid local job crafting scale. © 2021. by authors.
