A core facilitator of the transition from suicidal thoughts to suicide attempt is the individual's capacity for suicide. Suicide capacity is a theoretically universal concept adaptable for specific groups that is hypothesised to comprise three contributing factors: acquired capability, for example, previous self-harm; dispositional, such as genetic influences and practical, knowledge of and access to lethal means. Given that suicide capacity as a concept is continuing to develop, a review and synthesis of the current literature is timely to ensure future research and development of suicide prevention strategies are based on evidential knowledge. The aim of this review is to map the available evidence to provide an overview of factors that contribute to an adult's capacity for suicide.
This review will encompass five stages. Studies will be identified through broad search strings applied to 11 academic databases: Academic Search Ultimate, APA PsycArticles, APA PsycINFO, CINAHL, Psychology & Behavioural Sciences, & Sociology Source Ultimate via EBSCOHost Megafile Ultimate; PubMed; Science Direct; Wiley Online; Taylor & Francis and ProQuest dissertations and theses. Grey literature databases and key suicide organisations will also be searched for relevant literature. Two reviewers will independently screen titles and abstracts then review full texts to identify articles meeting inclusion criteria. Articles will be assessed for eligibility based on suicide attempt history, primary research study design, language and publication date. Data from eligible full texts will be extracted using a predesigned template for analysis. The synthesisation method will be textual narrative synthesis with an incorporated quality appraisal checklist tool.
Ethics approval is not required for this scoping review as no human participants are involved. Study findings will be shared with key suicide organisations, through peer-reviewed publications, and conference presentations.
从自杀念头向自杀企图转变的核心促成因素是个体的自杀能力。自杀能力是一个理论上普遍适用的概念，可以适应特定群体，假设它包括三个促成因素：习得能力，例如之前的自我伤害；性格，如遗传影响和实际情况，例如了解和获得致命手段。鉴于自杀能力作为一个概念仍在不断发展，对当前文献进行审查和综合是及时的，以确保未来的自杀预防策略研究和发展基于证据知识。本综述的目的是绘制现有证据，概述导致成年人自杀能力的因素。
本综述将包括五个阶段。研究将通过广泛的搜索字符串在 11 个学术数据库中识别：学术搜索终极版、APA PsycArticles、APA PsycINFO、CINAHL、心理学与行为科学、EBSCOHost Megafile 终极版中的社会学来源；PubMed；Science Direct；Wiley Online；Taylor & Francis 和 ProQuest 论文和论文。还将搜索灰色文献数据库和主要自杀组织，以获取相关文献。两名评审员将独立筛选标题和摘要，然后审查全文以确定符合纳入标准的文章。根据自杀企图史、主要研究设计、语言和出版日期评估文章的资格。使用预先设计的模板从合格的全文中提取数据进行分析。综合方法将是文字叙述综合，并纳入质量评估检查表工具。
由于本范围综述不涉及人类参与者，因此不需要伦理批准。研究结果将通过同行评议的出版物和会议报告与主要自杀组织分享。
