Abstract

Objectives: The study examined the psychometric properties of the Nightmare Distress Questionnaire (NDQ) in veterans with a provisional posttraumatic stress disorder (PTSD) diagnosis and trauma-related nightmares.

Method: Participants were 659 Australian Defence Force veterans who completed online questionnaires for a larger study investigating military-civilian transition. Analyses included exploratory factor analysis, and evaluation of internal consistency and convergent and divergent validity in a subsample of 191 veterans meeting provisional PTSD diagnostic criteria and endorsing trauma-related nightmares. An independent samples t-test assessed discriminant validity, comparing NDQ scores between participants with (n = 280) and without (n = 379) a provisional PTSD diagnosis.

Results: Principal-axis factoring suggested a one-factor solution comprising 10 items that explained 51.46% of the variance in nightmare distress. The NDQ demonstrated strong internal consistency, and correlations with validated measures supported convergent and divergent validity. NDQ scores were significantly higher for veterans with a provisional PTSD diagnosis.

Conclusions: Findings offer initial evidence of the NDQ's validity and reliability to assess trauma-related nightmare distress among veterans. We provide novel insights into the NDQ's utility for researchers and clinicians working with veteran populations, including its ability to differentiate veterans based on PTSD symptomatology.

退伍军人创伤后噩梦困扰问卷的心理测量特征。

目的：研究临时创伤后应激障碍（PTSD）退伍军人的噩梦困扰问卷（NDQ）的心理测量特征。方法：参与者是659名澳大利亚国防军退伍军人，他们完成了一项调查军民过渡的大型研究的在线问卷。分析包括探索性因素分析，评估191名符合创伤后应激障碍临时诊断标准并认可创伤相关噩梦的退伍军人的内部一致性、收敛效度和发散效度。独立样本t检验评估判别效度，比较临时诊断为PTSD的参与者（n = 280）和未诊断为PTSD的参与者（n = 379）的NDQ得分。结果：主轴分解提出了一个由10个项目组成的单因素解决方案，解释了51.46%的噩梦困扰方差。NDQ显示出很强的内部一致性，并且与验证测量的相关性支持收敛效度和发散效度。临时诊断为PTSD的退伍军人的NDQ得分明显更高。结论：研究结果初步证明了NDQ在评估退伍军人创伤相关噩梦困扰方面的有效性和可靠性。我们为研究退伍军人群体的研究人员和临床医生提供了关于NDQ效用的新见解，包括它基于PTSD症状区分退伍军人的能力。

期刊介绍： Behavioral Sleep Medicine addresses behavioral dimensions of normal and abnormal sleep mechanisms and the prevention, assessment, and treatment of sleep disorders and associated behavioral and emotional problems. Standards for interventions acceptable to this journal are guided by established principles of behavior change. Intending to serve as the intellectual home for the application of behavioral/cognitive science to the study of normal and disordered sleep, the journal paints a broad stroke across the behavioral sleep medicine landscape. Its content includes scholarly investigation of such areas as normal sleep experience, insomnia, the relation of daytime functioning to sleep, parasomnias, circadian rhythm disorders, treatment adherence, pediatrics, and geriatrics. Multidisciplinary approaches are particularly welcome. The journal’ domain encompasses human basic, applied, and clinical outcome research. Behavioral Sleep Medicine also embraces methodological diversity, spanning innovative case studies, quasi-experimentation, randomized trials, epidemiology, and critical reviews.
