| Abstract: | This study used multilevel structural equation modeling (MSEM; Preacher, Zyphur, &; Zhang, 2010) to examine within-person processes that give rise to quarrelsome behavior in interactions between romantic partners. Based on Interpersonal Theory and Adult Attachment Theory, we hypothesized that a person's quarrelsome behavior would be predicted by (a) the direct effect of the partner's quarrelsome behavior, (b) an indirect effect mediated by the person's perceptions of the partner's quarrelsome behavior, and (c) an indirect effect mediated by the person's felt security. Using an event-contingent recording methodology, both partners in 93 cohabiting community couples reported independently on their quarrelsome behavior, felt security, and perceptions of the partner's quarrelsome behavior in interactions with each other during a 20-day period. Findings (see Figure 1) supported a direct effect of partner's increases in quarrelsome behavior on person's increases in quarrelsome behavior. This association was partly accounted for by perceptions of partner's behavior and felt security following these perceptions. The more a person perceived the partner as engaging in quarrelsome behavior, the more the person engaged in quarrelsome behavior indirect effect = .016, 95% CI (.009 ? .022)]. Furthermore, the person's perception of greater quarrelsomeness in the partner's behavior was associated with decreases in the person's felt security, which in turn were related to increases in a person's quarrelsome behavior indirect effect = .009, 95% CI (.005 ? .013)]. No gender differences were found. Findings indicate that a partner's increase in quarrelsome behavior is partly related to a person's increase in quarrelsome behavior in part to the extent that the person perceives the behavior as quarrelsome and consequently feels insecure during the interaction. Findings illustrate an application of MSEM for assessing multilevel mediation in the dyadic context. Moreover, the results suggest that theory and therapeutic interventions should consider interpersonal perceptions as the first link in the chain of affective and behavioral reactions to the interpersonal behaviors of others. |
