Prompt, effective CPR greatly increases the chances of survival in out-of-hospital c ardiac arrest. However, it is often not provided, even by people who have previously undertaken training. Psychological and behavioural factors are likely to be important in relation to CPR initiation by lay-people but have not yet been systematically identified.
Aim: to identify the psychological and behavioural factors associated with CPR initiation amongst lay-people.
Systematic review Data sources: Cochrane Library, MEDLINE, EMBASE, CINAHL, PsycInfo and Google Scholar.
Primary studies reporting psychological or behavioural factors and data on CPR initiation involving lay-people published (inception to 31 Dec 2021).
Potential studies were screened independently by two reviewers. Study characteristics, psychological and behavioural factors associated with CPR initiation were extracted from included studies, categorised by study type and synthesised narratively.
One hundred and five studies (150,820 participants) comprising various designs, populations and of mostly weak quality were identified. The strongest and most ecologically valid studies identified factors associated with CPR initiation: the overwhelming emotion of the situation, perceptions of capability, uncertainty about when CPR is appropriate, feeling unprepared and fear of doing harm. Current evidence comprises mainly atheoretical cross-sectional surveys using unvalidated measures with relatively little formal testing of relationships between proposed variables and CPR initiation.
Preparing people to manage strong emotions and increasing their perceptions of capability are likely important foci for interventions aiming to increase CPR initiation. The literature in this area would benefit from more robust study designs.

及时有效的心肺复苏术（CPR）大大增加了院外心脏骤停患者的生存机会。然而，即使是接受过培训的人，也往往无法提供心肺复苏术。心理和行为因素可能与非专业人员进行心肺复苏术的启动有关，但尚未得到系统的确定。
目的：确定与非专业人员进行心肺复苏术启动相关的心理和行为因素。
系统评价。数据来源：Cochrane 图书馆、MEDLINE、EMBASE、CINAHL、PsycInfo 和 Google Scholar。
报告心理或行为因素以及涉及非专业人员心肺复苏术启动的数据的原始研究，发表时间（从成立到 2021 年 12 月 31 日）。
两名审查员独立筛选潜在的研究。从纳入的研究中提取与心肺复苏术启动相关的研究特征和心理行为因素，按研究类型进行分类，并进行叙述性综合。
确定了 105 项研究（涉及 150820 名参与者），这些研究具有不同的设计、人群和大多是弱质量。最强和最具生态有效性的研究确定了与心肺复苏术启动相关的因素：情况的压倒性情绪、对能力的感知、对何时进行心肺复苏术适当性的不确定性、感到准备不足和害怕造成伤害。目前的证据主要包括使用未经验证的测量方法的非理论性横断面调查，以及对提出的变量与心肺复苏术启动之间的关系进行的正式测试相对较少。
使人们能够应对强烈的情绪并增强他们的能力感，这可能是旨在增加心肺复苏术启动的干预措施的重要重点。该领域的文献将受益于更稳健的研究设计。
