The purpose of this study was to test theoretical propositions advanced by Meyer and Herscovitch (2001) concerning the interactive effects of affective, normative, and continuance commitment on focal (staying intentions) and discretionary (citizenship) behavior. Study measures were gathered from a sample of 545 hospital employees. Several a priori predictions regarding commitment profile differences were confirmed. Significant three-way interactions were found for both staying intentions and citizenship behavior. The pattern of relations for both behavioral criteria partially confirmed the hypotheses, but also provided evidence of possible "context effects" whereby the meaning and implications of the commitment components varies as a function of the other components. These effects were most notable for normative commitment and may offer new insight into the nature of this construct. Implications for commitment theory and its application were discussed.
