Abstract
Background. Obsessive-compulsive disorder (OCD) is a serious, disabling illness. Family members are frequently involved by attempting to stop rituals or by performing rituals for their relative. Factors associated with family accommodation of OCD have been largely overlooked in the literature. This study aims to identify the frequency and clinical predictors of OCD family accommodation behaviors.
Methods. Participants include those with a first admission to the McLean/Massachusetts General Hospital OCD Institute (N = 110). The Family Accommodation Scale was completed independently by family members. Univariate relationships between factors and family accommodation were assessed via graphs, parametric and non-parametric testing. Multiple regression analyses modeled relationships between family accommodation and predictor variables.
Results. Family accommodation was reported in 96.9% of cases, and predominantly occurred at least daily (59.1% of cases). Most common behaviors included providing reassurance and waiting for ritual completion. Two of 13 potential predictors were significantly correlated with family accommodation both in univariate regression analysis and in the final regression model (F = 10.15; p < 0.0001; R-square = 0.17; adjusted R-Square = 0.15). These include OCD severity (p = 0.0007) and the cleaning/contamination symptom dimension (p = 0.03).
Conclusions. Family accommodation is ubiquitous in OCD. Psychoeducation regarding potential deleterious effects of accommodation must not be overlooked in management of this illness.
