People who self-harm are at high risk for future suicide and often suffer considerable emotional distress. Depression is common among people who self-harm and may be an underlying driver of self-harm behaviour. Self-harm is often repeated, and risk of repetition is highest immediately after an act of self-harm. Readily accessible brief talking therapies show promise in helping people who self-harm, but further evaluation of these approaches is needed. A brief talking therapy intervention for depression and self-harm has been designed for use in a community setting. This mixed methods feasibility study with repeated measures will examine the feasibility and acceptability of the Community Outpatient Psychological Engagement Service for Self-Harm (COPESS) for people with self-harm and depression in the community, compared to routine care. Sixty participants with a history of self-harm within the last six months, who are also currently depressed, will be recruited to take part in a feasibility single-blind randomised controlled trial (RCT). Participants will be randomised 1:1 to receive COPESS plus treatment as usual (TAU) or TAU alone. Recruitment will be via General Practitioners (GP) and self-referral. Assessment of feasibility and acceptability will be assessed via quantitative and qualitative methods including measures of recruitment and retention to the feasibility trial, participants’ experience of therapy, completion/completeness of outcome measures at relevant time-points and completion of a service use questionnaire. The results will indicate whether it is feasible to conduct a definitive full trial to determine whether COPESS is a clinically and cost effective intervention for people who self-harm in the community. Qualitative and quantitative data will in addition help identify potential strengths and/or challenges of implementing brief community-based interventions for people who self-harm.

自残社区门诊心理治疗参与服务 (COPESS)：可行性试验方案

自我伤害的人未来自杀的风险很高，并且经常遭受相当大的情绪困扰。抑郁症在自残者中很常见，并且可能是自残行为的潜在驱动因素。自残行为经常重复发生，自残行为发生后再次发生的风险最高。容易获得的简短谈话疗法显示出帮助自残者的希望，但需要进一步评估这些方法。针对抑郁症和自残的简短谈话治疗干预已设计用于社区环境。与常规护理相比，这种重复测量的混合方法可行性研究将检查社区自残心理参与服务 (COPESS) 对社区中自残和抑郁症患者的可行性和可接受性。将招募 60 名在过去六个月内有自残史、目前也患有抑郁症的参与者参加一项可行性单盲随机对照试验 (RCT)。参与者将按 1:1 随机分配接受 COPESS 加常规治疗 (TAU) 或单独接受 TAU。招聘将通过全科医生 (GP) 和自我推荐进行。可行性和可接受性的评估将通过定量和定性方法进行评估，包括可行性试验的招募和保留措施、参与者的治疗经验、相关时间点结果措施的完成/完整性以及服务使用问卷的完成。结果将表明进行明确的全面试验是否可行，以确定 COPESS 是否是对社区中自残者的临床和具有成本效益的干预措施。此外，定性和定量数据将有助于确定为自残者实施简短的基于社区的干预措施的潜在优势和/或挑战。NCT04191122 于 2019 年 12 月 9 日注册。
