[Family accommodation and an obsessive-compulsive disorder: a meta-analysis and systematic review]

Obsessive-compulsive disorder (OCD) in youth ≤ 18 years is frequently associated with family accommodation. However, the current literature lacks scientific evidence specifically examining this association.

To clarify the association between family accommodation and OCD symptoms and to define the role of family therapy in the treatment of OCD in youth ≤ 18 years.

A meta-analysis and systematic review focused on the relationship between family accommodation and OCD symptoms in youth ≤ 18 years.

Fourteen studies were included, encompassing a total of 1,263 youth aged ≤ 18years with OCD. A significant association was found with a moderate effect size of r = 0.45 (95% CI: 0.35-0.54; p < 0.001). This association was identified exclusively in the domain of cleaning/contamination. Family accommodation decreased significantly following family therapy, and this reduction was significantly correlated with a decrease in OCD symptoms.

Family therapy focused on family accommodation appears to hold a critical role in the treatment of OCD. This approach can enhance parental alignment to sustain a more structured and boundary-setting parenting style. Future research should explore the impact of (empathetic) boundary-setting on OCD-symptoms, as well as the influence of the broader social context.
