Background: Individuals recovering from a suicide attempt may benefit from support provided by informal carers, that is, family members and other support persons, who may require support themselves. Aims: This systematic review aims to identify and synthesize available literature on the effectiveness of psychosocial interventions for this carer population. Method: A search of peer-reviewed literature in five databases was carried out. Studies using any design were eligible and results were synthesized using a narrative review. Results: Eight articles reporting on seven quantitative studies met the eligibility criteria. This included three studies on interventions designed specifically for informal carers and four studies on interventions designed for persons who have made a suicide attempt, and which involved their informal carers. Overall, informal carers were satisfied with support and psychosocial interventions they received. Interventions were related to some improvements in carers' mental health outcomes, lowered burden, and improved ability to provide care. There were mixed results regarding family functioning and quality of life. Limitations: No studies from lower- and middle-income countries were identified and the small number of heterogeneous studies precluded conducting a meta-analysis. Conclusion: Given the low number of studies and their overall poor quality, this review can only draw preliminary conclusions. More high-quality intervention studies are needed to formulate recommendations for effective psychosocial support for family members and other informal support persons after a suicide attempt.

对自杀未遂者的家庭成员和其他非正式支持者进行心理社会干预的有效性。

背景：从自杀未遂中恢复的个人可能会受益于非正式照顾者提供的支持，即家庭成员和其他支持者，他们可能需要自己的支持。目的：本系统评价旨在确定和综合现有的关于社会心理干预对该护理人群的有效性的文献。方法：检索五个数据库中的同行评议文献。使用任何设计的研究都符合条件，并使用叙述性审查综合结果。结果：八篇报道七项定量研究的文章符合资格标准。这包括三项专门针对非正式照料者设计的干预措施研究和四项针对企图自杀者设计的干预措施研究，这些研究涉及非正式照料者。全面的，非正式照顾者对他们获得的支持和社会心理干预感到满意。干预措施与护理人员心理健康结果的一些改善、减轻负担和提高护理能力有关。关于家庭功能和生活质量的结果好坏参半。局限性：没有确定来自低收入和中等收入国家的研究，并且少量异质研究排除了进行荟萃分析。结论：鉴于研究数量少且总体质量较差，本次审查只能得出初步结论。需要更多高质量的干预研究来制定建议，以便在自杀未遂后为家庭成员和其他非正式支持人员提供有效的社会心理支持。
