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

Background: 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.

Aim: 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.

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

Results: 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.

Conclusion: 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.
