The aim of this study was to examine parts of the Valle rand (1997) hierarchical
model of intrinsic and extrinsic work motivation within a work context. For the most
part, the results of this study are consistent with predictions based on the model. Three
important work factors, perceived autonomy support, pay satisfaction and perceived job
characteristics were positively related to workers' perceived work competence, perceived
work autonomy and self-determined work motivation. Further, perceived work
competence and perceived work autonomy mediated the effect o f perceived autonomy
support, pay satisfaction and perceived job characteristics on self-determined work
motivation. Self-determined work motivation, in turn, positively affected workers’ job
satisfaction
