On the global and specific nature of psychological need satisfaction and work motivation in predicting employees' wellbeing: a self-determination theory perspective

Using data from 708 French-Canadian nurses, the present study relies on self-determination theory (SDT) and its proposed motivation mediation model to examine the associations between need satisfaction, work motivation, and various manifestations of psychological wellbeing (work satisfaction, emotional exhaustion, and turnover intentions). To increase the precision and accuracy of these analyses, we relied on analytic approaches that explicitly account for the dual global/specific nature of both work motivation and need satisfaction. Results revealed that nurses' global psychological need satisfaction, and their specific autonomy and competence satisfaction, were positively associated with their global self-determined work motivation and specific intrinsic motivation. In turn, global self-determined work motivation and specific intrinsic motivation were associated with more desirable outcome levels. Nurses' global need satisfaction and specific autonomy satisfaction were also directly associated with more desirable outcome levels. Our results provided support for a partially mediated version of SDT's motivation mediation model.
