Effectiveness of online OurRelationship and ePREP programs for low-income military couples.

Military couples need and desire relationship interventions. Online interventions improve access; however, their effectiveness within the military population is untested. Using a subsample from a larger randomized controlled trial of OurRelationship and ePREP online relationship programs for low-income couples, this study examined baseline characteristics of military compared with civilian couples enrolled (Aim 1), treatment effects within military couples (Aim 2), and treatment differences between military and matched civilian participants (Aim 3). Military couples (n = 90 couples) in which 1 or both partners were active duty (11%) or veterans (89%) were selected from the larger randomized controlled trial along with a matched civilian sample selected using propensity scores. No differences were found between military and civilian couples regarding baseline individual or relationship functioning. Program completion was lower among military couples (57%) compared with civilians (71%), whereas program satisfaction was equally positive. Among military couples, relationship satisfaction, conflict, emotional support, and breakup potential were significantly improved after treatment (between-groups d = 0.31-0.46) and maintained at follow-up; intimate partner violence and individual functioning domains did not improve. When comparing military and civilian samples, there was a pattern of stronger treatment impacts on individual functioning for civilians, although only the impact on insomnia evidenced a significant difference. These online relationship interventions improved relationship functioning for military couples. More research is needed to test these interventions among clinically impaired military populations and to explore potential for improving program completion and effects on relationship violence and individual wellbeing.
