Parental psychopathology in child and adolescent obsessive-compulsive disorder

Purpose To identify the lifetime prevalence of obsessive-compulsive disorder (OCD) and other psychiatric diagnoses in parents of OCD pediatric patients as well as the frequency of onset of psychiatric disorders in the 6 months prior to evaluation. Methods Parents (n = 63) of 32 children and adolescents (20 males and 12 females; mean age of 13.3 ± 2.4) with OCD and parents of (n = 63) 32 age and sex-matched controls with no psychiatric diagnosis were examined. The semi-structured SCID-I was used to identify axis I psychiatric disorders and SCIDII to evaluate personality disorders. Results Mothers of patients had significantly more psychiatric diagnoses than control mothers (P = 0.001). Only parents of patients had diagnosis of OCD (P = 0.01) and psychiatric diagnosis (Adjustment Disorders, Major Depression, Anxiety Disorders) with onset during the 6 months prior to evaluation (P = 0.001). The duration of disease in children appeared to be related to development of morbidity in parents (P = 0.04). Parents of patients also showed a higher incidence of personality disorders (P = 0.01), in particular avoidant (6 versus 1 parents, P < 0.055) and obsessivecompulsive (9 versus 2 parents, P = 0.016) personality disorders. Conclusions The findings suggest that there may be an excess of psychopathology in parents of children with OCD as compared to parents of pediatric and non-psychiatric patients. Adjustment disorders with depressive and anxious symptoms are significantly more frequent in mothers of OCD children after the onset of the disease
