ABSTRACT

The purpose of this study was to evaluate the main and interaction effects of PTSD and TBI on sleep outcomes in veterans. Post-deployment combat veterans (N = 293, 87.37% male) completed clinical interviews to determine diagnosis and severity of PTSD and deployment TBI history, as well as subjective measures of sleep quality, sleep duration, and restedness. Sleep-related medical diagnoses were extracted from electronic medical records for all participants. PTSD and TBI were each associated with poorer ratings of sleep quality, restedness, shorter sleep duration, and greater incidence of clinically diagnosed sleep disorders. Analyses indicated main effects of PTSD on sleep quality (p < .001), but no main effects of TBI. PTSD severity was significantly associated with poorer sleep quality (p < .001), restedness (p = .018), and shorter sleep duration (p = .015). TBI severity was significantly associated with restedness beyond PTSD severity (p = .036). There were no interaction effects between diagnostic or severity variables. PTSD severity is a driving factor for subjective ratings of sleep disturbance beyond PTSD diagnosis as well as TBI diagnosis and severity. Despite this, poor sleep was apparent throughout the sample, which suggests post-deployment service members may globally benefit from routine screening of sleep problems and increased emphasis on sleep hygiene.

本研究的目的是评估 PTSD 和 TBI 对退伍军人睡眠结果的主要影响和相互作用。部署后的战斗退伍军人（ N = 293，87.37% 男性）完成了临床访谈，以确定 PTSD 的诊断和严重程度和部署 TBI 病史，以及睡眠质量、睡眠持续时间和休息的主观测量。从所有参与者的电子病历中提取与睡眠相关的医疗诊断。 PTSD 和 TBI 均与较差的睡眠质量、休息时间、较短的睡眠时间以及临床诊断的睡眠障碍的发生率较高相关。分析表明 PTSD 对睡眠质量有主要影响 ( p < .001)，但 TBI 没有主要影响。 PTSD 严重程度与较差的睡眠质量 ( p < .001)、休息程度 ( p = .018) 和较短的睡眠时间 ( p = .015) 显着相关。 TBI 严重程度与 PTSD 严重程度之外的休息程度显着相关 ( p = .036)。诊断或严重程度变量之间没有交互作用。 PTSD 严重程度是除 PTSD 诊断以及 TBI 诊断和严重程度之外的睡眠障碍主观评级的驱动因素。尽管如此，整个样本中的睡眠质量很差，这表明部署后的服役人员可能会从全球范围内受益于对睡眠问题的常规筛查和对睡眠卫生的重视。
