Intimate partner cohesion and military unit cohesion: Different types of interpersonal relationships each uniquely predict soldier well-being

Abstract

Although research on military populations has found that measures of personal well-being are correlated with both intimate partner cohesion and military unit cohesion, it is not clear how these correlations should be interpreted. Based on Relationship Regulation Theory, it was expected that each type of interpersonal relationship would have independent effects, that each would uniquely predict outcomes, and that effects would remain significant after controlling for person-level traits and experiences, such as trait resilience and exposure to combat. A sample of 273 active-duty military personnel completed self-report measures of cohesion in two types of interpersonal relationships (intimate relationships and military unit relationships), two control variables (trait resilience and combat exposure), and three outcome variables (well-being, negative emotionality, and trauma-related stress). Results indicated that cohesion in the two types of relationships were minimally related to each other, but both correlated with outcome variables. Effects for each type of interpersonal relationship remained significant after controlling for the other type and controlling for trait resilience and combat exposure. The results suggest that the effects of interpersonal cohesion are best understood as reflecting experiences in specific types of relationships rather than general characteristics of people in those relationships.
