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-items) 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 (N = 111). A confirmatory factor analysis suggests that the original one-factor solution, with a correlated error-term, provides an excellent fit to the data, SBχ²(2) = 1.62, p = .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 p’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 LEO 职业压力因素，包括重大事件和轮班工作，预示着睡眠障碍，进而对健康、绩效和社区安全产生负面影响。患者报告的结果测量信息系统 - 睡眠障碍 4 项 (PROMIS SD4) 的开发是为了评估自我报告的睡眠质量、满意度和入睡困难。以前的研究表明 PROMIS-SD 简短形式（4、6 和 8 项）具有良好的心理测量特性；然而，在高压力的前线人群中对这种易于实施的措施的评估是有限的。本研究的主要目标是评估 PROMIS-SD4 在 LEO 样本中的有效性和可靠性 ( N = 111）。验证性因子分析表明，具有相关误差项的原始单因子解与数据非常吻合，SB χ ² (2) = 1.62，p  = .23，CFI = .99，RMSEA = . 12、SRMR = .01。PROMIS SD4 表现出良好的可靠性 (α = .85) 和在预期方向与心理困扰、积极健康结果、反应性和身体体验领域的收敛有效性相关性的证据（所有 p < .05 ）。结果表明 PROMIS-SD4 是衡量 LEO 睡眠障碍的有效且可靠的方法。
