Alexithymia is a problem of emotion regulation and for this reason alone may relate to suicidality. This article investigates the evidence for a direct relationship. It explores the possibility of an additional role for interoception in future research.
A scoping review of peer-reviewed journal articles examining alexithymia and suicidality was undertaken, followed by a critical assessment of the overall state of the evidence base in relation to interoception.
The review identified 27 journal articles. The evidence base was heterogeneous, involving a variety of clinical and non-clinical samples, and displays mixed findings. The measurement of alexithymia (using the Toronto Alexithymia Scale) and management of confounding variables were identified as problematic in determining its relationship with suicidality.
The review was limited to published research in the English language. The review findings were not tested and refined by stakeholders. Some of the research studies cited in the critical assessment of interoception were themselves subject to the limitations of the Toronto Alexithymia Scale.
The scoping review identified a collection of articles that were too diverse to permit a definitive answer to the research question. Interoception may provide a fruitful new avenue in understanding the relationship between emotion regulation and suicide.
述情障碍是一种情绪调节问题，仅就此而言，它可能与自杀有关。本文探讨了两者之间存在直接关系的证据。它还探讨了在未来研究中探索内感受在其中可能发挥额外作用的可能性。
对同行评审的期刊文章进行了述情障碍和自杀相关性的范围综述，随后对与内感受相关的整体证据基础进行了批判性评估。
综述共确定了 27 篇期刊文章。证据基础具有异质性，涉及各种临床和非临床样本，且结果存在差异。述情障碍的测量（使用多伦多述情障碍量表）和混杂变量的管理被确定为确定其与自杀之间关系的问题。
该综述仅限于英语发表的研究。综述结果没有通过利益相关者进行测试和完善。在对内感受进行批判性评估中引用的一些研究本身也受到多伦多述情障碍量表的限制。
范围综述确定了一系列文章，这些文章过于多样化，无法对研究问题给出明确答案。内感受可能为理解情绪调节与自杀之间的关系提供了一个富有成效的新途径。
