Sleep moderates symptom experience in combat veterans

Though sleep disturbance has shown to negatively affect outcomes related post-deployment conditions, it is unclear whether and how affects mental health symptoms beyond these conditions. We evaluated the independent moderating effects of quality on posttraumatic stress disorder (PTSD), depressive, neurobehavioral mild traumatic brain injury (TBI) PTSD diagnosis. Participants were 274 US combat veterans who deployed after 9/11. All completed diagnostic TBI interviews self-report measures quality, as well PTSD, symptoms. Only those passed symptom validity included in analyses. Hierarchical regression contribution TBI. Moderation analyses interactions between TBI, outcomes. Mild was only significantly associated with (p = .006) .003) diagnosis < .001), depressive .001) Sleep explained additional significant variance all three outcome also moderated (ΔR2 .01, p .023). subjectively therefore must be interpreted this context. These results provide support that an contributing factor should considered etiology complaints.
