Measuring "we-ness" in couple relationships: A social identity approach.

Research on couple relationships has increasingly focused on the concept of "we-ness", the subjective closeness of the couple bond, as crucial to predicting relationship outcomes including satisfaction and dissolution. However, diverging perspectives on the definition, terminology, and measurement of this concept persist. We drew upon social identity theorizing to clarify the nature of we-ness and investigate its predictive utility. Participants were 375 members of the general community in long-term intimate relationships. The sample were aged 18-74 (M = 37.22; SD = 12.00) and 69% were women. Participants completed seven measures of we-ness drawn from both the couple literature and the social identity literature. We used exploratory factor analyses to establish the latent structure of we-ness, and regression analyses to examine the utility of each we-ness factor in predicting relationship satisfaction and likelihood of dissolution. A four-factor solution was extracted and the factors were labeled couple identity, partner liking, relationship orientation, and partner similarity. Each of the four factors explained unique variance in relationship quality, with couple identity being most strongly associated with positive outcomes. We conclude that couple research can fruitfully draw upon social identity theorizing in conceptualizing we-ness. This has implications both for more effectively measuring key concepts and for more precisely targeting interventions in couple therapy.
