Given the importance of family accommodation for the course, treatment and prognosis of anxiety in pediatric populations, we conducted a meta-analysis to estimate the magnitude and potential moderators of the relationship between accommodation and anxiety severity. Study selection criteria were: (1) included quantitative measures of accommodation and anxiety severity, (2) sampled participants younger than 19 years, (3) a sample size greater than 10, (4) reported statistical data needed to compute effect sizes, and (4) be in English or Spanish. Search procedures included assessment of electronic databases, systematic reviews and empirical studies, and email inquiries. Effect size was Pearson correlation coefficient, assuming a random-effects model. Positive moderate association was observed for measures administered to parents. This was moderated by the percentage of children with separation anxiety and selective mutism. Global effect sizes were small for measures administered to children and when accommodation was reported by parents and anxiety by children. Implications for assessment and treatment are discussed.
