The aim was to establish the potential reduction in non-fatal suicidal behaviour (NFSB) that could be achieved by treating common mental disorders (CMDs) among persons receiving HIV treatment. Data were collected from antiretroviral therapy (ART) patients in South Africa (n = 688). Structured Clinical Interviews assessed CMDs and the Mini International Neuropsychiatric Interview assessed 1-month prevalence of NFSB and suicide risk. Population Attributable Risk (PAR) analysis established the potential reduction in prevalence of NFSB and suicide risk that could be achieved by treating CMDs, with the simplifying assumption of a causal relationship between psychopathology and suicidality. Treating CMDs could result in as much as a 63.9% proportional reduction in the prevalence of suicide ideation, 84.2% proportional reduction in the prevalence of suicide plan, and 63.4% proportional decrease in prevalence of suicide risk. There is potential to significantly reduce NFSB among ART patients. Pragmatic trials are needed to evaluate the effects of treating CMDs in HIV treatment centres.

目的是确定潜在的非致命自杀行为（NFSB）的减少，这可以通过治疗接受HIV治疗的人中的常见精神障碍（CMD）来实现。数据来自南非的抗逆转录病毒疗法（ART）患者（n = 688）。结构性临床访谈评估了CMD，Mini International Neuropsychiatric访谈评估了NFSB的1个月患病率和自杀风险。人口归因风险（PAR）分析确定了通过治疗CMD可以实现的NFSB患病率和自杀风险的潜在降低，并简化了心理病理与自杀之间的因果关系假设。治疗CMD可以使自杀观念的发生率按比例减少多达63.9％，[84]。自杀计划的患病率成比例降低2％，自杀风险的患病率成比例降低63.4％。在ART患者中有可能显着降低NFSB。需要进行务实试验来评估在HIV治疗中心治疗CMD的效果。
