The measurement equivalence of job satisfaction ratings from physicians and nurses working in intensive care units was tested in the present study. Seventy-two nurses and 72 physicians completed the Safety Attitudes Questionnaire, which contains five items about job satisfaction. Measurement equivalence across nurses and physicians of the job satisfaction ratings was examined via multiple-group confirmatory factor analysis. The results indicated that physicians and nurses use the same metric when providing ratings for this job satisfaction measure. The primary implication from the present study is that nurses and physicians conceptualize job satisfaction in a similar manner. This implication needs to be extended to other survey measures of interest to health services researchers. Future areas of research are discussed.
