Familial Predictors of Treatment Outcome in Childhood Anxiety Disorders

To determine whether family factors are predictive of outcome in children with anxiety disorders who are receiving cognitive-behavioral treatment. Participants were 61 children aged 8 to 12 years (mean = 10.0, SD = 1.4) with Axis I anxiety disorders who had been referred to a large Toronto children's hospital. Parents and children completed measures assessing family functioning, parenting stress, parental frustration, and parental psychopathology before and after treatment. Outcome measures included clinician-rated functioning (Children's Global Assessment Scale) and self-and parent-rated anxiety (Revised Children's Manifest Anxiety Scale). Child ratings of family dysfunction and frustration predicted clinician-rated improvement (total R2 = 0.28, p < .001). Mother and father reports of family dysfunction, and maternal parenting stress, predicted mother-rated child improvement (total R2 = 0.18, p < .01). Father-rated somatization and child reports of family dysfunction and frustration predicted child-rated improvement (total R2 = 0.25, p < .001). Several family factors improved with treatment. Family dysfunction appears to be related to less favorable treatment outcome in children with anxiety disorders.
