背景:情感,认知,与自杀相关的结果有关的冲动性行为方面可以通过UPPS模型进行调查,以与消极和积极紧迫性相关的多维术语概念化这些方面,缺乏预谋和毅力,寻求感觉。这项系统评价和荟萃分析提供了对冲动性各个方面在自杀意念和行为发展中的作用的全面理解。
方法:我们对六个数据库进行了系统搜索(PsycINFO,心术,PubMed,MEDLINE,Scopus,和WebofScience),直到2023年5月5日。总的来说,49项研究符合系统评价标准,其中37例纳入17.898例患者的荟萃分析.额外的适度分析包括年龄,性别,样品状态,国家的研究行为,评估工具,自杀相关结果的类型,学习质量,和研究设计。
结果:我们发现冲动性和自杀相关结果之间存在显著关系。特别是,与冲动相关的情感方面显示出与自杀意念和尝试的关联比认知和行为维度更强,推荐自杀相关维度中情感方面的主要参与-积极和消极。
结论:数量有限的研究可能对适度分析的能力产生负面影响。此外,对于大多数方面的冲动,纵向研究数量有限,无法检验研究设计的调节作用.
结论:本研究支持冲动性在自杀意念和行为中的作用,确定冲动的情感成分是最重要的,从临床和诊断的角度提供了显著的贡献。
The affective, cognitive, and behavioral aspects of impulsivity involved in suicide-related outcomes can be investigated through the UPPS model, which conceptualizes these facets in multidimensional terms related to negative and positive urgency, lack of premeditation and perseverance, and sensation seeking. This systematic
review and meta-analysis provided a comprehensive understanding of the role of all facets of impulsivity in the development of suicidal ideation and behaviors.
We conducted a systematic search on six databases (PsycINFO, PsycARTICLES, PubMed, MEDLINE, Scopus, and Web of Science) until May 5,2023. Overall, 49 studies met the criteria for systematic
review, of which 37 were included in a meta-analysis of data from 17.898 individuals. Additional moderation analyses included age, gender, sample status, country of study conduct, assessment instruments, type of suicide-related outcome, study quality, and research design.
We found significant relationships between aspects of impulsivity and suicide-related outcomes. Specially, affective facets related to impulsivity showed a stronger association with suicidal ideations and attempts than cognitive and behavioral dimensions, recommending the main involvement of emotional aspects-positive and negative-in suicide-related dimensions.
The limited number of studies may have negatively impacted the power of moderation analyses. In addition, for most dimensions of impulsivity, the limited number of longitudinal studies did not allow to test the moderating role of research design.
This study supports the role of impulsivity in suicidal ideation and behavior, identifying the affective component of impulsivity as the most involved, providing a significant contribution from a clinical and diagnostic point of view.
