Sleep disturbances reflect a core dysfunction underlying Posttraumatic Stress Disorder (PTSD). Specifically, disruptive nocturnal behaviors (DNB) may represent PTSD-specific sleep disturbances. The Pittsburgh Sleep Quality Index Addendum for PTSD (PSQI-A) is self-report instrument designed to assess the frequency of seven DNB. The goal of this study was to examine the psychometric properties of the PSQI-A to characterize DNB in a group of participants with and without PTSD. Results indicate that the PSQI-A has satisfactory internal consistency and good convergent validity with two standard PTSD measures even when excluding their sleep-related items. A global PSQI score of 4 yielded a sensitivity of 94%, a specificity of 82%, and a positive predictive value of 93% for discriminating participants with PTSD from those without PTSD. The PSQI-A is a valid instrument for PTSD applicable to both clinical and research settings.
睡眠障碍反映了创伤后应激障碍（PTSD）潜在的核心功能障碍。具体而言，夜间干扰行为（DNB）可能代表PTSD特有的睡眠障碍。创伤后应激障碍匹兹堡睡眠质量指数附录（PSQI-A）是一种自我报告工具，旨在评估七种DNB的频率。本研究的目的是检验PSQI-A的心理测量特性，以描述一组有或无PTSD的参与者的DNB情况。结果表明，即使排除与睡眠相关的项目，PSQI-A仍具有令人满意的内部一致性，并且与两项标准PTSD测量方法具有良好的收敛效度。PSQI总得分4时，区分有PTSD的参与者和无PTSD的参与者的敏感性为94%，特异性为82%，阳性预测值为93%。PSQI-A是一种适用于临床和研究环境的PTSD有效工具。
