Abstract

Abstract: Introduction: PTSD has been associated with PSG-derived measurements of REM without atonia suggestive of RBD (Elliott et al, Sleep 2020 Mar 12;43(3):zsz237). Those findings have been reported in men in their mid-50's. In a relatively younger, diverse, help-seeking, psychiatric outpatient population enriched with PTSD, we examined the impact of demographics (self-reported gender, race, education) on the association between primary diagnosis of PTSD and probable RBD assessed with a validated questionnaire. Methods: Patients (n = 1, 658) were enrolled in a non-VA based treatment program for veterans. Patients underwent detailed diagnostic interviews and psychometrics. About 48% (549 men, 251 women; mean age 40.0 [SD = 9.6] years; 381 non-white) met criteria for PTSD. Typical other diagnoses included Axis I defined major depression and various anxiety disorders (without re-experiencing). Dream enactment was assessed with the previously validated University of Michigan RBD Questionnaire (UMRBDQ), completed either by patient or bedpartner. Mean (SD) and 50th% UMRBDQ scores were 0.52 (SD = 0.26) and 0.50. We defined likelihood of RBD by the 90th% of UMRBDQ score (> .80), based on previously published psychometrics, and used multiple logistic regression to define predictors of high vs low UMRBDQ scores. Predictors were diagnosis, self-reported gender (male), race (non-white [vs white]) and education (at least partial college). Results: PTSD diagnosis was strongly associated with positive UMRBDQ (31.5% vs 22.0%; OR = 1.77; 95% CI 1.40-2.23). Significant predictors were male gender (OR = 1.93, 95% CI 1.45-2.58) and non-white race (OR = 1.81; 95% CI 1.03-1.65) but not education (OR = 0.86; 95% CI 0.68-1.09). Models of 2-way interactions were all non-significant. Linear models employing UMRBDQ as continuous scores yielded similar results. Conclusion: These results confirmed that PTSD may be associated with higher likelihood of reported dream enactment and that these results were not dependent on self-reported gender, race or education.
