Examining associations among depressive symptoms, negative partner attributions, and relationship functioning in different‐gender couples using the actor‐partner interdependence mediation model

Abstract Negative attributions about the cause of and blame for relationship problems are highly predictive of relationship dysfunction and depression. Consequently, researchers have attempted to understand the role of negative relationship attributions in the association between depression and relationship functioning, with theory and research suggesting negative attributions may mediate the association between depression and relationship functioning. However, these studies were conducted on individuals, not couples. Including a couple of data and employing a dyadic design can provide a more holistic picture of the associations among these variables. The present study used the actor‐partner interdependence mediation model (APIMeM) to examine associations among depressive symptoms, relationship functioning, and negative partner attributions. Different‐gender couples ( N = 200) seeking couples’ clinical services completed measures of negative relationship attributions, relationship distress, and depressive symptoms. Results revealed depressive symptoms to be indirectly related to one's own and one's partner's relationship functioning through one's own negative causal attributions. Actor and partner effects of responsibility attributions and depressive symptoms on relationship functioning were also observed. Results underscore the possible mechanistic role of negative attributions—particularly causal attributions—in maintaining the depression‐relationship dysfunction association.
