Обзор

The goal of this clinical trial is to learn if self-help book can be used to treat obsessive-compulsive disorder (OCD) in adolescents aged 10 to 17. The main questions it aims to answer are: Can adolescents and their parents effectively reduce the severity of the obsessive-compulsive symptoms in adolescents who are already stably taking medications through self-help books? What are the characteristics of adolescents who are best suited to use self-help intervention book to treat obsessive-compulsive symptoms? Researchers will compare the use of a self-help books plus medication with medication alone to see if the combination of the self-help intervention and drug treatment can improve the obsessive-compulsive symptoms of adolescents more effectively. Participants will: * Read one chapter of a self-help book and complete the corresponding exercise each week for 12 weeks * Visit the clinic before and after intervention for checkups and tests
