Promoting couples' resilience to relationship obsessive compulsive disorder (ROCD) symptoms using a CBT-based mobile application: A randomized controlled trial.

Relationship Obsessive Compulsive Disorder (ROCD) is a disabling form of obsessive-compulsive disorder (OCD) centering on interpersonal relationships. Previous findings suggest ROCD symptoms are particularly detrimental to romantic relationships. In this randomized controlled trial (RCT), we assessed influence a CBT-based mobile application used by both partners on resilience to ROCD symptoms, cognitions, and relationship dissatisfaction. The app consists of brief, daily exercises targeting OCD symptoms, related cognitions and attachment insecurities. Heterosexual couples (Ncouples = 103; Mage = 26.15) were randomly assigned to individually use a mobile application for 15 days (n = 49 couples) or to a control group (n = 54 couples). All participants completed questionnaires at baseline (T1), 15 days from baseline (T2), and 45 days from baseline (T3). All couples also underwent an ROCD resilience task at T2. Intention-to-treat analyses revealed that, in contrast to the control group, couples who used the app exhibited enhanced resilience in the resilience task, as well as measures of ROCD symptoms, cognitions, and relationship dissatisfaction. These observed effects persisted even at the 1-month follow-up. Concurrent use of brief mobile delivered cognitive training by both romantic partners may foster resilience in romantic couples.
