BACKGROUND Little is known about the social validity of self-harm prevention apps for young adolescents with severe mental health problems who repeatedly self-harm. OBJECTIVE We assessed the acceptability, use and safety of BlueIce, a self-harm prevention app for young adolescents who self-harm. METHODS Mixed methods study involving a content analysis of postuse interviews. Participants were a clinical group of 60 UK adolescents aged 12-17 with repeated self-harm, randomised to receive BlueIce. FINDINGS BlueIce was used by 57/60 (95%) respondents with 47/57 (82%) using BlueIce when thinking about self-harm. 17/47 (36%) who were thinking about self-harm used it on more than six occasions with 36/47 (77%) reporting that BlueIce prevented at least one episode of self-harm. 33/47 (70%) reported occasions when they used the app but still went on to self-harm. Reasons why the app was not used or not helpful included feeling too distressed, a negative mindset, prior decision to self-harm or forgetting. BlueIce was rated 4.09 (SD=0.75) out of 5 stars, with high mean ratings out of 10 for ease of use (8.70, SD=1.37) and good for acceptability (7.68, SD=2.05) and helpfulness (6.77, SD=1.72). No respondent identified BlueIce as triggering any episode of self-harm. CONCLUSION These findings are consistent with previous evaluations and highlight the acceptability, use and safety of BlueIce. Self-reports indicate that BlueIce prevented some episodes of self-harm. CLINICAL IMPLICATIONS Our results highlight the acceptability of the BlueIce self-harm app for young adolescents who repeatedly self-harm.

BlueIce 自残预防应用程序的可接受性、使用和安全性：来自击败青少年自残 (BASH) 随机对照试验的定性研究结果。


背景 对于患有严重心理健康问题且反复自残的青少年的自残预防应用程序的社会有效性知之甚少。目的 我们评估了 BlueIce（一款针对自残青少年的自残预防应用程序）的可接受性、使用和安全性。方法 混合方法研究涉及使用后访谈的内容分析。参与者是由 60 名 12-17 岁、反复自残的英国青少年组成的临床小组，随机接受 BlueIce 治疗。调查结果 57/60 (95%) 的受访者使用 BlueIce，其中 47/57 (82%) 在考虑自残时使用 BlueIce。 17/47 (36%) 考虑过自残的人使用过超过六次，其中 36/47 (77%) 的人报告 BlueIce 至少预防了一次自残。 33/47 (70%) 的受访者表示，他们曾使用该应用程序，但仍继续自残。该应用程序未被使用或没有帮助的原因包括感觉太痛苦、消极心态、之前决定自残或忘记。 BlueIce 的评分为 4.09 (SD=0.75)，满分 5 星，在易用性 (8.70，SD=1.37)、可接受性 (7.68，SD=2.05) 和帮助性 (6.77，SD= 1.72）。没有受访者认为 BlueIce 会引发任何自残事件。结论 这些发现与之前的评估一致，强调了 BlueIce 的可接受性、使用性和安全性。自我报告表明 BlueIce 阻止了一些自残行为。临床意义 我们的结果凸显了 BlueIce 自残应用程序对于反复自残的青少年的可接受性。
