The Nightmare Disorder Index Questionnaire (NDI) was developed to measure the impact of nightmares. The purpose of this study was to investigate the psychometric properties of NDI among Chinese adolescents. This study investigated the validity and internal consistency of the Nightmare Disorder Index Chinese (NDI-CV) among 6014 Chinese adolescents who completed the NDI-CV, Nightmare Distress Questionnaire-Chinese Version (NDQ-CV), Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), Chinese Adolescent Daytime Sleepiness Scale (CADSS), Generalized Anxiety Disorder-7 Questionnaire (GAD-7), and Patient Health Questionnaire-9 (PHQ-9). In addition, we investigated the test-retest reliability of the NDI-CV among 423 adolescents who completed a retest of the NDI-CV after a 2-week interval. Finally, NDI-CV demonstrated good psychometric properties in a sample of Chinese adolescents (Cronbach's α coefficient of 0.876), and the 95% confidence interval for the 2-week retest correlation coefficient was 0.675-0.977 (p < 0.001).
噩梦障碍指数问卷 (NDI) 是为测量噩梦的影响而开发的。本研究旨在调查 NDI 在中国青少年中的心理测量特性。本研究调查了 6014 名完成 NDI-CV、噩梦困扰问卷中文版 (NDQ-CV)、匹兹堡睡眠质量指数 (PSQI)、失眠严重程度指数 (ISI)、中国青少年日间嗜睡量表 (CADSS)、广泛性焦虑障碍-7 问卷 (GAD-7) 和患者健康问卷-9 (PHQ-9) 的中国青少年中噩梦障碍指数中文 (NDI-CV) 的有效性和内部一致性。此外，我们还调查了 423 名青少年在两周间隔后完成 NDI-CV 复测的 NDI-CV 的重测信度。最后，NDI-CV 在中国青少年样本中表现出良好的心理测量特性 (Cronbach's α 系数为 0.876)，两周复测相关系数的 95%置信区间为 0.675-0.977(p<0.001)。
