The efficacy of an internet-based cognitive-behavioral therapy intervention for child anxiety disorders.

Objective: To evaluate the efficacy of an Internet-based cognitive-behavioral therapy (CBT) approach to the treatment of child anxiety disorders.

Methods: Seventy-three children with anxiety disorders, aged 7-12 years, and their parents were randomly assigned to either an Internet-based CBT (NET) or wait-list (WL) condition. Clinical diagnostic assessment and parent and child questionnaires were completed before and after treatment. The NET condition was reassessed at 6-month follow-up.

Results: At posttreatment assessment, children in the NET condition showed small but significantly greater reductions in anxiety symptoms and increases in functioning than WL participants. These improvements were enhanced during the 6-month follow-up period, with 75% of NET children free of their primary diagnosis.

Conclusions: Internet delivery of CBT for child anxiety offers promise as a way of increasing access to treatment for this population. Future research is needed to examine ways to increase treatment compliance and further enhance the impact of treatment.
