Intrinsic Need Satisfaction: A Motivational Basis of Performance and Weil‐Being in Two Work Settings¹

Studies in 2 work organizations tested a self‐determination theory based model in which employees' autonomous causality orientation and their perceptions of their managers' autonomy support independently predicted satisfaction of the employees' intrinsic needs for competence, autonomy, and relatedness, which in turn predicted their performance evaluations and psychological adjustment. Path analysis indicated that the self‐determination theory model fit the data very well and that alternative models did not provide any advantage.
