Self-efficacy, values, and complementarity in dyadic interactions: integrating interpersonal and social-cognitive theory.

Dyadic interactions were analyzed using constructs from social-cognitive theory (self-efficacy and subjective values) and interpersonal theory (interpersonal circumplex [IPC] and complementarity). In Study 1, the authors developed a measure of efficacy for interpersonal actions associated with each IPC region--the Circumplex Scales of Interpersonal Efficacy (CSIE). In Study 2, the authors used the CSIE and the Circumplex Scales of Interpersonal Values (which assesses the subjective value of interpersonal events associated with each IPC region) to predict the dominance expressed and satisfaction experienced by members of 101 same-sex dyads trying to solve a murder mystery. Structural equation modeling analyses supported both social-cognitive and interpersonal theory. A social-cognitive person-variable (dominance efficacy) and an interpersonal dyadic-variable (reciprocity) together predicted dominant behaviors. Likewise, both a social-cognitive variable (friendliness values) and an interpersonal variable (correspondence of friendliness efficacy) predicted satisfaction. Finally, both shared performance outcomes and dynamic interpersonal processes predicted convergence of collective efficacy beliefs within dyads.
