睡眠障碍反映了创伤后应激障碍 (PTSD) 的核心功能障碍。具体来说，破坏性夜间行为（DNB）可能代表创伤后应激障碍（PTSD）特有的睡眠障碍。匹兹堡 PTSD 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。本研究的目的是检查 PSQI-A 的心理测量特性，以表征一组患有或不患有 PTSD 的参与者的 DNB。结果表明，即使排除与睡眠相关的项目，PSQI-A 与两种标准 PTSD 测量也具有令人满意的内部一致性和良好的收敛效度。总体 PSQI 评分为 4 分时，区分患有 PTSD 的参与者和没有 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 是适用于临床和研究环境的 PTSD 有效工具。 (C) 2004 Elsevier Inc. 保留所有权利。
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. (C) 2004 Elsevier Inc. All rights reserved.
