Non-suicidal-self-injury (NSSI) in adolescents needing inpatient treatment is a serious health risk behaviour. NSSI-specific treatment programs for inpatients hardly exist. “Cut the Cut” (CTC) is a new treatment program in intervals, addressing this problem. Aim of this pilot-study was to evaluate acceptability and feasibility of CTC. 23 female inpatients (12 CTC, 11 control, aged 15–17; mean = 16.80, SD.70) engaging in NSSI were evaluated for service user satisfaction, frequency, and severity of NSSI at T1 (admission), T2 (discharge after interval 1, CTC-group) and T3 (discharge). A qualitative interview was performed at T3. Significant improvement in NSSI-frequency was given (T1–T3: CTC p = 0.010; control p = 0.038). Severity of NSSI reduced slightly (mild NSSI: CTC p = 0.022, control p = 0.087; severe NSSI: CTC p = 0.111, control p = 0.066). Satisfaction of parents (T3 mean 28.38) and adolescents (T3 mean 26.11) in CTC was rated high. CTC is a feasible treatment option for inpatients engaging in NSSI. Further studies over time are needed.

需要住院治疗的青少年的非自杀性自伤（NSSI）是一种严重的健康风险行为。几乎不存在针对住院患者的 NSSI 特异性治疗方案。“Cut the Cut” (CTC) 是一种新的间歇治疗方案，旨在解决这个问题。这项试点研究的目的是评估 CTC 的可接受性和可行性。对参与 NSSI 的 23 名女性住院患者（12 名 CTC，11 名对照组，15-17 岁；平均值 = 16.80，SD.70）在 T1（入院）、T2（间隔后出院）的服务用户满意度、频率和 NSSI 严重程度进行了评估1、CTC-组）和T3（放电）。在 T3 进行了定性访谈。NSSI 频率显着改善（T1-T3：CTC p = 0.010；对照 p = 0.038）。NSSI 的严重程度略有降低（轻度 NSSI：CTC p = 0.022，对照 p = 0.087；严重 NSSI：CTC p = 0.111，对照 p = 0.066）。父母（T3 平均 28.38）和青少年（T3 平均 26.11）对 CTC 的满意度被评为高。对于 NSSI 住院患者来说，CTC 是一种可行的治疗选择。需要随着时间的推移进行进一步的研究。
