Somatic symptom disorders and related conditions (SSD-RC), along with depression and anxiety disorders, are among the most common mental disorders. Disturbances in emotion regulation (ER) are considered a key factor in the etiology and pathogenesis of SSD-RC. The present review aims to summarize relevant research on ER in SSD-RC and integrate results in the extended process model of ER. We conducted a systematic literature search in PubMed, PsycInfo, Psyndex, and Web of Science. After screening and systematic quality appraisal, 105 (n = 29332 participants) out of 2118 identified studies were included. Correlations with somatic symptoms in general and clinical populations as well as group comparisons with non-SSD-RC groups were included to summarize effects. We found evidence for deficits in the identification process of ER, especially reduced emotional clarity and ER self-efficacy, in patients with SSD-RC. SSD-RC were also significantly associated with a deviant pattern of habitual strategies (selection process) including a more frequent use of expressive suppression and a less frequent use of cognitive reappraisal. However, for both the identification and selection stages, there were many studies that did not find evidence for alterations in SSD-RC. Furthermore, self-report data suggests impairments in implementing ER. Experimental studies are scarce and have not found conclusive evidence for ER implementation deficits in SSD-RC. In addition to experimental studies, particularly ecological momentary assessments are needed to better understand potential alterations regarding ER in SSD-RC. Clinical interventions that target the identification of the need for ER, self-efficacy, and the repertoire of different strategies currently appear most promising.

躯体症状障碍和相关病症 (SSD-RC) 以及抑郁症和焦虑症是最常见的精神障碍之一。情绪调节（ER）的紊乱被认为是SSD-RC病因和发病机制的关键因素。本综述旨在总结 SSD-RC 中 ER 的相关研究，并将结果整合到 ER 的扩展过程模型中。我们在 PubMed、PsycInfo、Psyndex 和 Web of Science 中进行了系统的文献检索。经过筛选和系统的质量评估，105 ( n = 29332 名参与者）在 2118 项已确定的研究中被纳入。包括与一般和临床人群中躯体症状的相关性以及与非 SSD-RC 组的组比较以总结效果。我们在 SSD-RC 患者中发现了 ER 识别过程中存在缺陷的证据，特别是情绪清晰度和 ER 自我效能感降低。SSD-RC 还与习惯性策略（选择过程）的异常模式显着相关，包括更频繁地使用表达抑制和不太频繁地使用认知重新评估。然而，对于识别和选择阶段，有许多研究没有发现 SSD-RC 改变的证据。此外，自我报告数据表明实施 ER 存在障碍。实验研究很少，也没有发现 SSD-RC 中 ER 实施缺陷的确凿证据。除了实验研究外，还需要特别是生态瞬时评估，以更好地了解 SSD-RC 中 ER 的潜在变化。以识别对 ER、自我效能和不同策略的需要为目标的临床干预目前似乎最有希望。
