Effectiveness of Video Teletherapy in Treating Child and Adolescent Obsessive-Compulsive Disorder with Exposure and Response Prevention: a Retrospective Longitudinal Observational Study

BackgroundAn effective primary treatment for obsessive-compulsive disorder (OCD) in children and adolescents as well as adults is exposure and response prevention, a form of cognitive-behavioral therapy. Despite strong evidence supporting the efficacy and effectiveness of exposure and response prevention from studies in research and real-world settings, its clinical use remains limited. This underuse is often attributed to access barriers such as the scarcity of properly trained therapists, geographical constraints, and costs. Some of these barriers may be addressed with virtual behavioral health, providing exposure and response prevention for OCD through video teletherapy and supplemented by app-based therapeutic tools and messaging support between sessions. While studies of teletherapy exposure and response prevention in adults with OCD have shown benefits in research and real-world settings in both small and large samples, studies in children and adolescents thus far have been in small samples and limited to research settings. ObjectiveThis study reports on the real-world effectiveness of teletherapy exposure and response prevention for OCD in the largest sample (N=2173) of child and adolescent patients to date. MethodsChildren and adolescents with OCD were treated with live, face-to-face video teletherapy sessions, with parent/caregiver involvement, using exposure and response prevention. Assessments were conducted at baseline, after 7-11 weeks, and after 13-17 weeks. Additionally, longitudinal assessments of OCD symptoms were performed at weeks 18-30, 31-42, and 43-54. ResultsTreatment resulted in a median 37.3% decrease in OCD symptoms at 13-17 weeks, and 53.4% of youth met full response criteria at this point. In addition, there were significant reductions in the severity of depression, anxiety, and stress symptoms. The median amount of therapist involvement was 13 appointments and 11.5 hours. Further, symptom improvements were maintained, or improved upon, in the longitudinal assessment period. ConclusionsThese results show that remote ERP treatment, assisted by technology, can effectively improve symptoms in children and adolescents with OCD in a real-world setting. Notable outcomes were achieved in a relatively small amount of therapist time, demonstrating its efficiency. These findings have implications for widespread dissemination of accessible, evidence-based care for children and adolescents with OCD.
