摘　　要：目的:评价中文版入睡前觉醒量表(PSAS)测评短暂失眠障碍(BID)患者的效度和信度。方法:选取170例BID患者和150例正常睡眠者(NS),完成PSAS、医院焦虑抑郁量表(HADS)、失眠严重程度指数(ISI)。其中,72例BID患者在3个月后接受PSAS、HADS、ISI重测。结果:BID组的PSAS分值呈现正态分布,PSAS分值与HADS、ISI分值均呈正相关(r=0.55、0.40,均P <0.01)。探索性因子分析和平行分析结果显示PSAS趋向于双因子结构(躯体觉醒和认知觉醒),方差解释值为55.84%,条目负荷为0.46~0.89。BID组的PSAS及其分量表分值均高于NS组(均P<0.001)。受试者工作特征曲线(ROC)显示PSAS的最佳划界分为32/33 (灵敏度0.72,特异度0.81)。Chronbachα和Spearman Brown分半信度分别为0.91和0.76,条目与总分的相关系数为0.41~0.85 (均P<0.01),重测信度为0.37 (P<0.01)。此外,PSAS分值变化率与ISI、HADS分值变化率均呈正相关(均P <0.05)。结论:中文版PSAS测评BID患者的睡前觉醒程度具有良好的效度和信度。Objective:To test the validity and reliability of the Chinese version of the Pre-sleep Arousal Scale(PSAS)in patients with brief insomnia disorder(BID).Methods:Totally 170 patients with BID and 150 normal sleepers(NS)were recruited.All participants were assessed with the PSAS,Hospital Anxiety and Depression Scale(HADS)and Insomnia Severity Index(ISI).After 3 months,72 patients with BID were retested with the PSAS,HADS and ISI.Results:The PSAS scores of BID group were characteristic of a normal distribution.The PSAS total scores were positively correlated with the scores of HADS and ISI(r=0.55,0.40,Ps<0.01).Two factors of so-matic and cognitive arousal were extracted in PSAS by the exploratory factor analysis and parallel analysis,interval variance value was 55.84%,and the load scores of items were 0.46-0.89.The scores of PSAS and its subscales were higher in the BID group than in the NS group(Ps<0.001).The best cut-off score for the overall PSAS was found at 32/33 and had high sensitivity(0.72)and specificity(0.81).The Cronbach′sαcoefficient and the Spearman Brown split reliability were 0.91 and 0.76,respectively,the correlation coefficients between the items and total score ranged from 0.46 to 0.89(Ps<0.01),and the test-retest reliability was 0.37(P<0.01).Addi-tionally,rate of change of PSAS scores was positively correlated with the rate of change of HADS scores and ISI scores(Ps<0.05).Conclusion:The Chinese version of PSAS is a reliable and valid instrument to assess pre-sleep arousal in patients with brief insomnia disorder.
