Cognitive behavior therapy (CBT) is the recommended first-line intervention for children and adolescents with obsessive-compulsive disorder (OCD), but is not broadly accessible. Internet-delivered CBT (ICBT) with minimal therapist support is efficacious and cost-effective, at least in the short term. Whether the therapeutic gains of ICBT for OCD are sustained in the long run is unknown. In this study, 61 adolescents with OCD who participated in a randomized trial of ICBT were followed-up 3 and 12 months after treatment. The proportion of treatment responders and remitters remained stable from post-treatment to 3-month follow-up and increased significantly from 3-month to 12-month follow-up. This study suggests that the gains of ICBT for youth with OCD are not only maintained long-term, but that further improvements continue to occur during follow-up.

认知行为疗法 (CBT) 是针对患有强迫症 (OCD) 的儿童和青少年的推荐一线干预措施，但尚未广泛普及。至少在短期内，在最少治疗师支持的情况下通过互联网提供的 CBT (ICBT) 是有效且具有成本效益的。从长远来看，ICBT 对强迫症的治疗效果是否能持续尚不清楚。在这项研究中，61 名参加 ICBT 随机试验的强迫症青少年在治疗后 3 个月和 12 个月进行了随访。从治疗后到 3 个月的随访，治疗有效者和缓解者的比例保持稳定，从 3 个月到 12 个月的随访显着增加。这项研究表明，对于强迫症青少年来说，ICBT 的效果不仅可以长期维持，而且在随访过程中还会继续出现进一步的改善。
