The Empowering Function of the Belief in a Just World for the Self: Trait-Level and Experimental Tests of Its Association With Positive and Negative Affect.

Belief in a just world for the self (BJW-self) is a resource that promotes adaptive functioning. We theorize that BJW-self has such an effect because it is empowering. This article reports on four studies ( = 967) testing whether BJW-self encourages more positive and less negative affect indirectly through empowerment. There was support for this hypothesis at a trait level across all studies, and specifically in Study 1. Experimental evidence, however, was more complex. Study 2 demonstrated the causal effect of the mediator, empowerment, on affect. Study 3 demonstrated that affirming BJW-self enhanced empowerment with an associated increase in positive affect and reduced negative affect. Study 4 showed that enhancing empowerment did not significantly influence the effect of affirmed BJW-self on affect, but blocking empowerment did, although this finding is qualified by no significant effect on empowerment. We discuss the theoretical implications of these findings, and the challenges of experimentally manipulating BJW-self.
