Relationship obsessions are a relatively new OCD symptom cluster, previously misdiagnosed as a basic character trait of the individual as one who is dependent and controlling in an interpersonal relationship. The OCD sufferer obsesses about whether they truly love their partner, are they a good enough mother, are they genuinely enjoying time with their family, etc.? Topics covered include differential diagnosis, rituals embedded in interactions, underlying scrupulosity and perfectionism obsessions, and obsessing about obsessing. Strategies for treatment include imaginal scripts, conversations with family members, in vivo parenting, technology enhanced ERPs, and addressing familial issues following treatment.
