Abstract

Introduction

Suicide is a leading cause of death worldwide. Although inconsistent, impulsivity has been identified as a risk factor for suicidal thoughts and behaviors, and these inconsistent findings can largely be attributed to varying operationalizations of impulsivity. As such, the UPPS model of impulsivity provides a clear definition of impulsivity and its associated features that may provide utility in clarifying unreliable findings between impulsivity and suicide. This review aimed to summarize relevant information pertaining to the UPPS model of impulsivity and suicide.

Methods

This systematic review followed the a priori guide outlined by the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. Articles were gathered from PsycINFO, PsycArticles, Scopus, and PubMed.

Results

Twenty-eight articles were reviewed and analyzed. Most articles reviewed reported on indirect (i.e., through mediators and moderators) associations between the UPPS dimensions and suicidal behaviors. Additionally, results noted limited between-group differences in UPPS facets among individuals with a history of suicide attempts and those without a history of suicide attempts, those with a history of suicide attempts and individuals with suicide ideation, and those with suicide ideation and those without suicide ideation, with the exception of lack of premeditation.

Discussion

The results of this review indicate support for the UPPS model of impulsivity as a theoretical starting point when examining the relation between impulsivity and suicide. Further, findings are helpful for clinicians and case conceptualization. Particularly, suicide risk assessment and treatment would be impacted based on impulsivity traits and suicide history.

冲动和自杀的 UPPS 模型：系统文献回顾

摘要

介绍

自杀是世界范围内的主要死亡原因。虽然不一致，但冲动已被确定为自杀想法和行为的风险因素，这些不一致的发现在很大程度上可归因于冲动的不同操作化。因此，UPPS 的冲动性模型提供了对冲动性及其相关特征的明确定义，这些特征可能有助于澄清冲动性和自杀之间的不可靠发现。本综述旨在总结与 UPPS 冲动和自杀模型有关的相关信息。

方法

本系统评价遵循PRISMA（系统评价和元分析的首选报告项目）声明概述的先验指南。文章来自 PsycINFO、PsycArticles、Scopus 和 PubMed。

结果

审查和分析了 28 篇文章。大多数审查的文章都报告了 UPPS 维度与自杀行为之间的间接（即，通过调解人和调解人）关联。此外，结果指出，在有自杀未遂史和没有自杀未遂史的个体、有自杀未遂史和有自杀意念的个体、有自杀意念和没有自杀意念的个体之间，UPPS 方面的组间差异有限自杀意念，除了缺乏预谋。

讨论

本综述的结果表明，在研究冲动性与自杀之间的关系时，支持将冲动性的 UPPS 模型作为理论起点。此外，研究结果有助于临床医生和病例概念化。特别是，自杀风险评估和治疗会受到冲动性特征和自杀史的影响。
