0669 Disruptive Nocturnal Behaviors in PTSD Patients are Associated with More Severe Psychiatric Pathology
Bibliographic record
Abstract
Abstract Introduction The similarities and differences between trauma associated sleep disorder (TASD) and REM sleep behavior disorder (RBD) are unclear. However, both REM sleep parasomnias are associated with disruptive nocturnal behaviors (DNB) that manifest as episodes of sleep-related vocalizations, and/or complex motor behaviors. Patients who have more DNB are more likely to have a higher prevalence of PTSD. Methods In a cross-sectional study, we examined the relationship between DNB severity and the severity of psychiatric symptoms in PTSD patients. 73 civilian patients with histories of complex developmental trauma (age 47.0 ±13.3 years; 89.6% female) met the DSM-5 criteria for moderate-to-severe PTSD. PTSD Checklist for DSM-5 (PCL-5) was used to obtain an index of current PTSD severity (37.41 ± 19.84; PCL-5 >30 cutoff for PTSD). DNB was defined as the sum of the two items 1f and 1g in the Pittsburgh Sleep Quality Index PTSD Addendum (PTSD-A). The participants rated how often during the past 1 month they had trouble sleeping because of the following: (PTSD-A Item1f) “Had episodes of terror or screaming during sleep without fully awakening” and (PTSD-A Item1g) “Had episodes of ‘acting out’ their dreams, such as kicking, punching, running or screaming”. We used a stepwise multiple regression analysis with DNB as the dependent variable and the variables described below as independent variables. Results We determined the following relationships: 1. PCL-5 (r=0.359, p=0.002); 2. Brief Symptom Inventory which includes Somatization (r=0.476,p< 0.001);Obsessive-compulsiveness (r=0.429, p< 0.001); Interpersonal Sensitivity (r=0.337, p=0.004); Depression (r=0.398, p< 0.001); Anxiety (r=0.449,p< 0.001); Hostility (r=0.577, p< 0.001); Phobic Anxiety (r=0.353, p=0.002); Paranoid Ideation (r=0.412, p< 0.001); and Psychoticism (r=0.414, p< 0.001); 3. Insomnia Severity Index (r=0.363, p=0.002); 4. Beck Suicide Scale or BSS (r=0.268, p=0.025); 5.Beck Anxiety Inventory (r=0.472, p< 0.001); and 6. Fear of Sleep(r=0.493,p< 0.001). Fear of Sleep Inventory (FOS) (Beta=0.442, t=4.258, p< 0.001) and Beck Scale for Suicidal Ideation (BSS) (Beta=0.300, t=2.887, p=0.005) emerged as the significant predictors of DNB. Conclusion DNB was correlated with a wide range of psychiatric pathology in PTSD. This suggests that DNB could be an integral feature of severe PTSD. To our knowledge, this has not been previously reported. Support (if any) None

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
