Abstract

Background

The exploration of inter- and intra-individual variability in suicidal ideation (SI) is vital to suicide research. However, this research relies on the identification and measurement of standardized SI characteristics.

Objective

This review aimed to identify characteristics of SI examined in research, describe how these characteristics are measured, and assess how they are aligned with those included in the Columbia Suicide Severity Rating Scale (C-SSRS).

Methods

Four databases were systematically searched, and relevant data was extracted. The C-SSRS provided a framework for comparing SI names, measures and operational definitions.

Results

After comparing operational definitions of identified characteristics, five core domains emerged: (1) severity, (2) temporality, (3) variability, (4) controllability, and (5) deterrents/reasons for ideating. Except for variability, all SI characteristics in the literature were congruent with those measured in the C-SSRS.

Conclusions

This review highlighted conceptual and methodologic inconsistencies in the study of SI, specifically the nomenclature, measurement and definitions of SI characteristics. Standardized approaches to the study of SI characteristics are needed. These approaches will enhance accurate and reliable measurement of SI, allow for findings to be synthesized across studies and propel the exploration of inter and intra-individual SI variability leading to more individualized and effective SI treatment.

自杀意念的特征：系统回顾

摘要

背景

探索自杀意念（SI）的个体间和个体内变异对于自杀研究至关重要。然而，这项研究依赖于标准化 SI 特征的识别和测量。

客观的

本综述旨在确定研究中检查的 SI 特征，描述如何测量这些特征，并评估它们如何与哥伦比亚自杀严重程度评定量表 (C-SSRS) 中包含的特征保持一致。

方法

系统检索了四个数据库，提取了相关数据。C-SSRS 提供了一个用于比较 SI 名​​称、度量和操作定义的框架。

结果

在比较已识别特征的操作定义后，出现了五个核心领域：（1）严重性，（2）暂时性，（3）可变性，（4）可控性，以及（5）构思的威慑/原因。除变异性外，文献中的所有 SI 特征均与 C-SSRS 中测量的特征一致。

结论

这篇综述强调了 SI 研究中概念和方法上的不一致，特别是 SI 特征的命名、测量和定义。需要标准化的方法来研究 SI 特征。这些方法将增强 SI 的准确和可靠测量，允许跨研究综合结果，并推动对个体间和个体内 SI 变异性的探索，从而实现更加个性化和有效的 SI 治疗。
