Family accommodation of obsessional symptoms and naturalistic outcome of obsessive-compulsive disorder.

Accommodation of symptoms by families and expressed emotion (EE) may have a negative impact on the outcome of obsessive-compulsive disorder (OCD). The study examines the effect of family accommodation (FA) and EE on the 1-year naturalistic outcome of OCD. Patients with OCD who met the criteria for the Diagnostic and Statistical Manual of Mental Disorders-IV, text revision (DSM-IV TR; N=94) were followed up for 1 year and assessed every 3 months. Assessments included measurement of symptom severity, FA, EE and family burden. By the 12th month, the cumulative probability of remission was 58%. Non-remitters compared with remitters had a significantly higher FA, EE and family burden at the baseline and did not report significant reductions on any of the family variables over the year. In a Cox proportional hazard regression analysis, a higher FA at the baseline significantly predicted time to remission. FA of symptoms has a significant negative impact on the naturalistic outcome of OCD. This emphasises the need to design specific interventions to reduce FA for a better outcome.
