Emotion dysregulation in idiopathic rapid eye movement sleep behavior disorder
Bibliographic record
Abstract
STUDY OBJECTIVES: 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. METHODS: 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). RESULTS: 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. CONCLUSIONS: 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.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
