People's attributions for their own psychological problems are linked to their interpersonal behaviors and attitudes. However, depressed individuals' inferences about their romantic partners' attributions for their depressive symptoms have yet to be studied in relation to their perceptions of relationship quality. This study examined perceived support from and conflict with partners in relation to perceptions of partners' attributions for depression in 165 individuals experiencing at least mild depressive symptoms. After controlling for relevant demographic characteristics, perceived internal/controllable psychological attributions were related to greater perceived conflict and lower perceived support, and perceived controllable biological attributions were related to greater perceived conflict. Perceived external/uncontrollable psychological and uncontrollable biological attributions were unrelated to perceived support and conflict. Findings suggest that perceived attributions may help explain the link between depression, support, and conflict in romantic relationships.
