尽管对自杀过程的危险因素的临床研究积累了，但对自杀念头出现及其发展为行为的机制和途径的理解还不够。自杀过程已在多种心理学理论中被概念化，旨在阐明促成因素的相互作用。自杀立方模型和自杀三步理论中包含的中心概念之一是心理痛苦（精神痛苦或精神痛苦）。在过去的两个十年中，对心理疼痛的兴趣大大增加，特别是自从发现了疼痛处理系统与自杀的神经生物学之间的复杂联系以及丁丙诺啡推定的抗自杀作用之后。越来越多的证据支持在临床和非临床样本中经历心理痛苦与自杀意念和行为之间的关联。然而，与心理痛苦的概念及其在预测自杀行为中的作用有关的许多问题仍有待在未来的研究中得到解答。在这篇叙述性综述中，我们概述了这一概念的历史、心理疼痛的定义以及为其测量而开发的工具，总结了与自杀行为相关的心理疼痛的实证研究，并提出了心理临床研究的未来方向。疼痛和自杀行为。许多与心理痛苦的概念及其在预测自杀行为中的作用有关的问题仍有待未来研究回答。在这篇叙述性综述中，我们概述了这一概念的历史、心理疼痛的定义以及为其测量而开发的工具，总结了与自杀行为相关的心理疼痛的实证研究，并提出了心理临床研究的未来方向。疼痛和自杀行为。许多与心理痛苦的概念及其在预测自杀行为中的作用有关的问题仍有待未来研究回答。在这篇叙述性综述中，我们概述了这一概念的历史、心理疼痛的定义以及为其测量而开发的工具，总结了与自杀行为相关的心理疼痛的实证研究，并提出了心理临床研究的未来方向。疼痛和自杀行为。

Despite accumulation of clinical research on risk factors for suicidal process, understanding of the mechanisms and pathways underlying the emergence of suicidal thoughts and their progression to acts is insufficient. The suicidal process has been conceptualized in multiple psychological theories that have aimed to shed light on the interplay of contributing factors. One of the central concepts included in both the cubic model of suicide and the three-step theory of suicide is psychological pain (mental pain or psychache). Over the two last decades, interest in psychological pain has increased considerably, particularly since the discovery of the complex link between the pain processing system and the neurobiology of suicide, and the putative antisuicidal effect of buprenorphine. Growing evidence supports the association between experiencing psychological pain and suicidal ideation and acts in both clinical and non-clinical samples. However, many questions related to the concept of psychological pain and its role in prediction of suicidal behavior remain to be answered in future research. In this narrative review, we have outlined the history of the concept, the definition of psychological pain, and the tools developed for its measurement, summarized the empirical research on psychological pain in relation to suicidal behavior, and suggested future directions for clinical research on psychological pain and suicidal behavior.
