This article describes the early psychological counselling process of a sixteen-year-old boy with obsessive-compulsive disorder, whom I will call Bao. Bao came for help because of the “uncomfortable feeling” caused by uncontrollable stimuli and scary scenes that often appeared in his mind. He was also found to have a large number of obsessive-compulsive thoughts and behaviours during the counselling process. After he saw a psychiatrist, he was referred to the hospital for therapy. Bao's OCD was related to a strict superego and repressed sexual fantasies. After only ten sessions of treatment, “Bao” established a good relationship with the therapist, but his parents then decided to terminate treatment. This case report makes the point that work with adolescents must be accompanied by work with parents to relieve their anxiety, help to improve their relationship with their children, and in order to secure treatment.
