摘要
目的对睡眠障碍评定量表（SleepDysfunctionRatingScale,SDRS）进行信效度检验。方法选择符合CCMD-3的失眠症患者215例进行两次SDRS及临床总体印象量表（clinicalglobalimpressionscale-severi-ty,CGI-S）测试,两次间隔时间为3-7天。结果SDRS重测信度系数为0.89（P〈0.001）;各条目的Cronbachα系数较高（0.85-0.88）。SDRS与CGI-S的相关系数为0.70（P〈0.001）。因子分析显示除条目8和9具有相近的公共因子负荷之外,其他条目分别单独负荷不同的公共因子。因子载荷范围在0.73至0.95之间。结论SDRS具有较好的信度和效度。
Objective： Psychometric evaluation of Sleep Dysfunction Rating Scale （ SDRS ） for insomnia. Methotis ：The study sample consisted of 215 patients with insomnia （CCMD-3 ）. The length of the test-retest interval was either 3 to 7 days. Results. In insomnic patients, the overall SDRS global score correlation coefficient for test-retest reliability was 0. 89 （ P 〈 0. 001 ）. The items of SDRS homogeneity were high with Cronbach＇s alpha of 0. 85 - 0. 88. Valid- ity analyses showed high correlations between SDRS and CGI-S （ clinical global impression scale-severity ） data. The factor analysis showed that the factor loading and structure, which matched the structure of the scale approximately. The range of factor loading was between 0. 73 to 0. 95. Conclusion ：The SDRS has a high reliability and a good validity in patients with insomnia.
