To characterize emotion regulation strategies in patients with idiopathic REM sleep behavior disorder (iRBD) and to explore whether these strategies are associated with clinical symptoms.
In this cross-sectional multicenter study, a total of 94 polysomnography-confirmed iRBD patients (mean age, 67.6 years; men, 56%) and 50 healthy controls (mean age, 65.4 years; men, 48%) completed the Cognitive Emotion Regulation Questionnaire (CERQ), the Korean version of the RBD questionnaire-Hong Kong (RBDQ-KR), the Buss-Durkee Hostility Inventory (BDHI), the second edition of the Beck Depression Inventory (BDI-II), and the Korean version of the Montreal Cognitive Assessment (MoCA-K).
The iRBD group had lower CERQ adaptive scores than the control group, whereas the CERQ maladaptive scores were not significantly different between the groups. Among the CERQ adaptive subscales, the scores for positive refocusing, refocusing on planning, and positive reappraisal were significantly lower in the iRBD group than in the control group. Higher CERQ adaptive scores were correlated with lower scores on RBDQ-KR factor 1 (dream-related) and the BDI-II and higher MoCA-K scores but were not correlated with RBDQ-KR factor 2 (behavioral manifestation) or BDHI scores. Among the dream content-related items of RBDQ-KR factor 1, the CERQ adaptive score was associated only with frequent nightmares. No correlation was found between CERQ maladaptive scores and any variable except for a positive correlation with BDI-II scores.
Our results provide evidence of emotion regulation deficits in iRBD patients. Furthermore, these results were linked to dream-related factors, especially nightmares, along with depressive symptoms and cognitive impairment.
描述特发性 REM 睡眠行为障碍（iRBD）患者的情绪调节策略，并探讨这些策略是否与临床症状相关。
在这项横断面多中心研究中，共纳入 94 例经多导睡眠图（PSG）确诊的 iRBD 患者（平均年龄 67.6 岁，男性占 56%）和 50 例健康对照者（平均年龄 65.4 岁，男性占 48%）。所有研究对象均完成认知情绪调节问卷（CERQ）、韩国版 REM 睡眠行为障碍问卷-香港版（RBDQ-KR）、Buss-Durkee 敌意量表（BDHI）、贝克抑郁自评量表第二版（BDI-II）和蒙特利尔认知评估量表韩国版（MoCA-K）。
iRBD 组的 CERQ 适应性评分低于对照组，而两组的 CERQ 不适应性评分无显著差异。在 CERQ 适应性分量表中，iRBD 组的积极重新聚焦、重新聚焦于计划和积极重新评价评分显著低于对照组。较高的 CERQ 适应性评分与 RBDQ-KR 因子 1（梦境相关）和 BDI-II 评分较低以及 MoCA-K 评分较高相关，而与 RBDQ-KR 因子 2（行为表现）或 BDHI 评分无相关。在 RBDQ-KR 因子 1 的梦境内容相关项目中，仅与频繁噩梦相关的 CERQ 适应性评分。除了与 BDI-II 评分呈正相关外，CERQ 不适应性评分与任何变量均无相关性。
本研究结果为 iRBD 患者存在情绪调节缺陷提供了证据。此外，这些结果与梦境相关因素（特别是噩梦）、抑郁症状和认知障碍有关。
