Previous studies have reported a negative correlation between the Behavioral Activation System (BAS) and the depressive mood. However, which is the cause and which is the effect cannot be determined simply by evaluating the correlation coefficients. In a series of this study, we used non-normal structural equation modeling, which could provide a statistically plausible answer to the question on the path direction. We tested for the path direction between the variables of interest by statistically comparing all possible models. The models assuming a unidirectional path from the BAS to the depressive mood were consistently supported. This suggested that low BAS could be a predisposition to developing the depressive mood. These findings could enhance our understanding of the mechanism underlying the development of the depressive mood.
