Attachment insecurities and under-commitment in distressed couples: The role of positive and negative partner behaviors.

Research has rarely considered intermediate variables in the association between attachment insecurities and relationship commitment. Based on attachment theory and Rusbult's Investment Model, we tested whether positive and negative partner behaviors explain this association in 91 distressed couples undergoing therapy. Path analyses based on the Actor-Partner Interdependence Model revealed that individuals with attachment avoidance reported perceiving fewer positive behaviors from their partner, which was associated with their own higher under-commitment. Partners of individuals with avoidance also reported perceiving fewer positive partner behaviors, which was in turn associated with their own higher under-commitment. Partners of individuals with attachment anxiety perceived more positive behaviors from their partner, which was associated to their own lower under-commitment. Perceived negative partner behaviors were only directly associated with higher under-commitment. These findings imply that perceived positive partner behaviors may be a key aspect to target in relationship therapy in couples who present with high attachment insecurities.

How Do Partner Support, Psychological Aggression, and Attachment Anxiety Contribute to Distressed Couples' Relationship Outcomes?

Few studies have simultaneously looked at the relative contribution of positive and negative behaviors to understand relationship outcomes. This study examined the relative roles of perceived partner support and psychological aggression in two relationship outcomes-relationship satisfaction and the willingness to invest in the relationship-as well as the contribution of attachment anxiety as a moderator in 307 couples seeking relationship therapy. Path analyses revealed that perceived partner support was associated with individuals' own higher relationship satisfaction and willingness to invest in the relationship. Attachment anxiety moderated these associations. Perceived partner psychological aggression was not associated with relationship outcomes.
