Abstract

Objective

Intensive longitudinal methods (ILM), such as ecological momentary assessment (EMA) and daily diary, involve repeatedly assessing individuals over short periods of time and have been increasingly used to study suicidal thoughts and behaviors (STBs). Suicidal thoughts have been shown to vary over short periods of time and reports of STBs are subject to negative biases. Therefore, ILM are important methodological tools for studying STBs, ones that capture enhanced precision and realism of data compared to traditional survey methods. The present systematic review aims to provide a comprehensive overview of ILM used to study STBs, including the various EMA and daily diary methodologies used, the feasibility of those methodologies, and the ethical considerations in this line of research. This review also summarizes the characteristics of descriptive STB outcomes specific to the ILM data collection period.

Methods

A thorough search of PubMed and PsycINFO was conducted up to May 2020, resulting in twenty-eight papers reviewed.

Results and conclusions

The review of the studies showed that ILM are largely feasible and do not have a negative impact on participants. In addition, the reviewed studies revealed unique aspects of STBs, such as the variability of suicidal thoughts, that suggest that ILM are important methodologies to use when studying STBs. Gaps in the research and recommendations for future research are discussed.

• Highlights

• It is feasible to use ILM to study suicidality.

• ILM do not have a negative impact on participants with suicidality.

• Few studies have used ILM to study suicidality in diverse samples.

在自杀思想和行为研究中使用强化纵向方法：系统评价

摘要

客观的

强化纵向方法 (ILM)，例如生态瞬时评估 (EMA) 和每日日记，涉及在短时间内重复评估个体，并且越来越多地用于研究自杀念头和行为 (STB)。自杀念头已被证明在短时间内会发生变化，并且 STB 的报告受到负面偏见的影响。因此，ILM 是研究 STB 的重要方法学工具，与传统调查方法相比，这些工具可以捕获更高的数据精度和真实性。本系统评价旨在提供用于研究 STB 的 ILM 的全面概述，包括使用的各种 EMA 和每日日记方法、这些方法的可行性以及该研究方向的伦理考虑。

方法

截至 2020 年 5 月，对 PubMed 和 PsycINFO 进行了彻底搜索，最终审查了 28 篇论文。

结果和结论

对研究的回顾表明，ILM 在很大程度上是可行的，并且不会对参与者产生负面影响。此外，审查的研究揭示了 STB 的独特方面，例如自杀念头的可变性，这表明 ILM 是研究 STB 时使用的重要方法。讨论了研究中的差距和对未来研究的建议。

• 强调

• 使用 ILM 研究自杀是可行的。

• ILM 对有自杀倾向的参与者没有负面影响。

• 很少有研究使用 ILM 来研究不同样本中的自杀倾向。
