Organizational commitment and job satisfaction are important constructs of job attitudes. However, the causal order of these two constructs is controversial. This study adopts two approaches to explore the truths behind this controversy: (1) a common antecedents approach to exclude the potential impact of organizational image and trait positive affect; (2) an overall job attitudes approach to construct a second order framework. The analytic results suggest that there is a correlated but not causal relationship between affective organizational commitment and job satisfaction. Also, in terms of overall fit, the second order model is as good as the correlated model. A series of rigorous validation of these findings is urged.
