The purpose of this study was to describe the magnitude of the relationships between nurses' job satisfaction and the variables most frequently associated with it. A meta-analysis of data from 48 studies with a total of 15,048 subjects revealed that job satisfaction was most strongly associated with stress (-.609) and organizational commitment (.526). Seven variables had correlations between .20 and .50: communication with supervisor, autonomy, recognition, routinization, communication with peers, fairness, and locus of control. Four other variables frequently included in these studies had low correlations (less than .20): age, education, tenure, and professionalization. The influence of employment site, date of study, and measures used on the size and consistency of estimates was described.
