Family accommodation mediates the impact of childhood anxiety on functional impairment.

Background: Anxiety disorders are the most common childhood-onset psychiatric disorders and are extensively associated with child functional impairment. Data suggest that family accommodation plays a role in the association between anxiety severity and functional impairment in children, but more empirical evidence is needed.

Methods: Participants were 425 clinically anxious children (ages 6-17 years), and their mothers. We first examined associations between child anxiety symptom severity, family accommodation, and child functional impairment. Next, we investigated the hypothesized mediation pathway linking anxiety severity to child impairment through increased family accommodation using structural equation modeling. We tested two models: one using parent ratings of their child's anxiety and the other using the child's self-ratings. Finally, we estimated the effect sizes of the mediation pathway in both models.

Results: Family accommodation was significantly correlated with all the study variables. Child functional impairment was significantly correlated with parent-rated and self-rated child anxiety severity. Both structural equation models provided excellent fit for the data and supported the theoretical model by which family accommodation significantly explains part of the association between anxiety symptoms and functional impairment. The indirect effect sizes indicate that family accommodation accounts for between a fifth and a half of the impairment associated with symptom severity.

Conclusions: The data provide important empirical evidence that family accommodation mediates the association between child anxiety and functional impairment and accounts for up to 50 % of this association. These findings contribute to the growing understanding of the critical role of family accommodation and underscore the importance of assessing accommodation when evaluating and treating anxious children.
