OBJECTIVES This retrospective cohort study aims to understand the effectiveness of the Singular Therapeutic Project (STP) implemented in a Child Psychosocial Care Center in preventing recurrence of self-harm and suicide attempt (SA), by comparing the group of patients who adhered to the STP with the group that did not adhere completely. METHOD Data were collected from the medical records of adolescents with self-harm or SA during the period from 2015 to 2019. The primary outcomes analyzed were recurrence of SA, self-harm, and hospitalization; and the secondary outcomes analyzed were demographics, diagnosis, number of appointments, and negative life events. RESULTS A total of 228 adolescents were included. After multivariate analysis, social service consultations decreased risk in 94.6% (HR .054, 95% CI: .004-.681) of the cases, but risk was increased by 23 times if there was an episode of self-harm among family members and/or friends (HR 23.641, 95% CI: 1.394-400.8). Additionally, in terms of SA, adherence to family interventions reduced the risk by 66.2% (HR .338, 95% CI: .125-.913). Victims of prejudice, racism, homophobia, transphobia presented a 3.7-fold increased risk (HR 3.766, 95% CI: 1.058-13.401). CONCLUSION The STP interventions were effective in reducing the recurrence of self-harm and SAs in adolescents.

青少年自杀企图和自残的复发（RASS 研究）：单一治疗项目的有效性。

目的 这项回顾性队列研究旨在通过比较遵守 STP 的患者组，了解儿童心理社会护理中心实施的单一治疗项目 (STP) 在预防自残和自杀未遂 (SA) 复发方面的有效性与不完全遵守的小组。方法 收集 2015 年至 2019 年期间发生自残或 SA 青少年的病历数据。分析的主要结局是 SA 复发、自残和住院治疗；分析的次要结果是人口统计、诊断、预约次数和负面生活事件。结果 共有 228 名青少年被纳入。经过多变量分析，社会服务咨询降低了 94.6%（HR .054，95% CI：0.004-.681）病例的风险，但如果家庭成员发生自残行为，风险会增加 23 倍和/或朋友（HR 23.641，95% CI：1.394-400.8）。此外，就 SA 而言，坚持家庭干预可将风险降低 66.2%（HR 0.338，95% CI：0.125-0.913）。偏见、种族主义、恐同症、跨性别者恐惧症的受害者的风险增加 3.7 倍（HR 3.766，95% CI：1.058-13.401）。结论 STP 干预措施可有效减少青少年自残和 SA 的复发。
