Abstract
This study examined the relationship between caregivers’ and youths’ treatment expectations and characteristics of exposure tasks (quantity, mastery, compliance) in cognitive-behavioral therapy (CBT) for childhood anxiety. Additionally, compliance with exposure tasks was tested as a mediator of the relationship between treatment expectations and symptom improvement. Data were from youth (N = 279; 7–17 years old) enrolled in the Child/Adolescent Anxiety Multimodal Study (CAMS) and randomized to cognitive-behavioral therapy (CBT) or the combination of CBT and sertraline for the treatment of separation anxiety disorder, generalized anxiety disorder, and social phobia. Caregivers and youth independently reported treatment expectations prior to randomization, anxiety was assessed pre- and post-treatment by independent evaluators blind to treatment condition, and exposure characteristics were recorded by the cognitive-behavioral therapists following each session. For both caregivers and youths, more positive expectations that anxiety would improve with treatment were associated with greater compliance with exposure tasks, and compliance mediated the relationship between treatment expectations and change in anxiety symptoms following treatment. Additionally, more positive parent treatment expectations were related to a greater number and percentage of sessions with exposure. More positive youth treatment expectations were associated with greater mastery during sessions focused on exposure. Findings underscore the importance of addressing parents’ and youths’ treatment expectations at the outset of therapy to facilitate engagement in exposure and maximize therapeutic gains.
