Effect of a Family-Based CBT Self-Help Intervention for Adolescents With OCD

In this study, the investigators use selective serotonin reuptake inhibitors (SSRIs, i.e., sertraline, fluoxetine and fluvoxamine)and tricyclic drugs(i.e., clomipramine) approved by the State Food and Drug Administration (CFDA) for the treatment of OCD in children and adolescents. The drugs used in this study are commonly used in clinical practice and have a good safety profile. The maximum dosage shall not exceed the maximum dosage prescribed in the instruction manual, or the maximum dosage tolerated by the patients.

The self-help book used in this study was independently developed by members of our research team. Its content is based on Exposure and Response Prevention (ERP). Adolescent patients with OCD will be instructed to read one chapter of the self-help book each week and complete the corresponding exercises. This 12-week intervention will involve self-guided practice conducted by the adolescent and their family members.Throughout the intervention period, adolescents and their caregivers may contact the therapist via WeChat to ask questions and upload records of their completed exercises. The therapist will respond to any questions within 48 hours by sending written messages via WeChat, with each family receiving no more than 30 minutes of such written guidance per week. All therapists will be required to keep a weekly log of the time spent providing guidance to each participating family.If a participating family does not initiate contact, the therapist will not provide proactive guidance.
