The purpose of this study is to determine whether intrinsic motivation acts as a psychological mechanism that induces members' job crafting behavior in the relationship between goal orientation and job crafting. To explore this, we collected data by surveying full-time workers aging 19 or older online and used 333 participants for the final analysis. The results showed that mastery goal orientation positively predicted intrinsic motivation, and performance-approach goal orientation positively predicted both intrinsic and extrinsic motivation. Also, performance-avoidance goal orientation statically predicted extrinsic motivation. In addition, intrinsic motivation had a positive effect on job crafting, and relationship between goal orientation and job crafting was mediated by intrinsic motivation. Besides, a competition model was set up to check whether there is a mediating effect of extrinsic motivation on job crafting and compared with the research model. As a result, the research model that mediates job crafting only with intrinsic motivation was found to be a suitable and simple model. The implications and limitations of this study and directions for future research are addressed in the final part.
