Law enforcement officers (LEOs) are at increased risk for sleep disorders relative to the general population. Common LEO occupational stressors, including critical incidents and shift work, predict sleep disturbance, which in turn negatively impacts health, performance, and community safety. The Patient-Reported Outcomes Measurement Information System-Sleep Disturbance 4-item (PROMIS SD4) was developed to assess self-reported sleep quality, satisfaction, and difficulties falling asleep. Previous studies suggest PROMIS-SD short-forms (4-, 6-, and 8-item) have good psychometric properties; however, evaluation of this easily-administered measure in high-stress, frontline populations is limited. The primary goal of this study was to evaluate the validity and reliability of the PROMIS-SD4 in a sample of LEOs ( = 111). A confirmatory factor analysis suggests that the original one-factor solution, with a correlated error-term, provides an excellent fit to the data, SBχ(2) = 1.62, = .23, CFI = .99, RMSEA = .12, SRMR = .01. The PROMIS SD4 demonstrated good reliability (α = .85) and evidence of convergent validity correlations in the expected direction with domains of psychological distress, positive health outcomes, reactivity, and body experience (all 's < .05). Results suggest that the PROMIS-SD4 is a valid and reliable measure of sleep disturbance among LEOs.
与普通人群相比，执法人员（LEO）患睡眠障碍的风险更高。常见的执法人员职业压力源，包括重大事件和轮班工作，会导致睡眠障碍，进而对健康、工作表现和社区安全产生负面影响。患者报告结果测量信息系统睡眠障碍4项量表（PROMIS SD4）旨在评估自我报告的睡眠质量、满意度和入睡困难情况。先前的研究表明，PROMIS-SD简版量表（4项、6项和8项）具有良好的心理测量特性；然而，在高压力的一线人群中对这种易于使用的测量方法的评估有限。本研究的主要目的是评估PROMIS-SD4在一组执法人员样本（n = 111）中的有效性和可靠性。验证性因素分析表明，具有相关误差项的原始单因素解决方案与数据拟合良好，SBχ(2)= 1.62，p = .23，CFI = .99，RMSEA = .12，SRMR = .01。PROMIS SD4表现出良好的信度（α = .85），并且在预期方向上与心理困扰、积极健康结果、反应性和身体体验等领域具有收敛效度相关性（所有p值 < .05）。结果表明，PROMIS-SD4是一种评估执法人员睡眠障碍的有效且可靠的测量方法。
