| ［摘要］ 目的 验证中文版福特应激性失眠反应测验（FIRST-C）在短期失眠障碍（STID）患者中的心理测量学特征。方法 于2017年11月至2019年6月期间在南方医科大学南方医院门诊招募STID患者172例（STID组），另选取睡眠良好对照者（GSC）150名（GSC组）。采用FIRST-C、失眠严重程度指数（ISI）、艾普沃斯嗜睡量表（ESS）和医院焦虑抑郁量表（HADS）进行评估。其中72例STID患者在3个月后接受重测。结果 STID组的FIRST-C总分显著高于GSC组（P<0.05）。探索性因子分析显示，FIRST-C具有单因子结构，可解释方差百分比为51.04%，各条目因子载荷范围在0.405～0.828之间。STID组的FIRST-C评分与ESS评分呈中度正相关（rs=0.498，P<0.001），与HADS评分呈轻度正相关（rs=0.174，P=0.024），与ISI评分不相关（rs=0.001，P=0.995）。受试者工作特征（ROC）曲线分析结果显示FIRST-C鉴别STID和GSC的最佳划界分值为19.5分。信度分析显示，Cronbach′s α系数和Spearman-Brown分半信度分别为0.873、0.864，条目得分与总分的相关系数范围为0.326～0.752。3个月后复测FIRST-C总分与初测FIRST-C总分差异有统计学意义（t=5.440，P<0.001）。结论 FIRST-C评估STID患者的睡眠反应性具有较好的心理测量学特征。 |

| ［Abstract］ Objective To validate the psychometric characteristics of the Ford Insomnia Response to Stress Test—Chinese version(FIRST-C) in patients with short-term insomnia disorder(STID). Methods One hundred and seventy-two STID patients were recruited as the STID group from the outpatient clinic of Nanfang Hospital, Southern Medical University between November 2017 and June 2019, and 150 good-sleeper controls(GSC) were selected as the GSC group. The patients were evaluated using FIRST-C, Insomnia Severity Index(ISI), Epworth Sleepiness Scale(ESS), and the Hospital Anxiety and Depression Scale(HADS). Among them, 72 STID patients underwent retesting after 3 months. Results The total scores of FIRST-C in the STID group were significantly higher than those in the GSC group(P<0.05). Exploratory factor analysis revealed that FIRST-C exhibited a single-factor structure, explaining 51.04% of the variance, with item factor loadings ranging from 0.405 to 0.828. The FIRST-C scores in the STID group showed a moderate possitive correlation with ESS(rs=0.498, P<0.001), a mild correlation with HADS score(rs=0.174, P=0.024) and non significant correlation with ISI score(rs=0.001, P=0.995). The receiver operating characteristic(ROC) curve analysis revealed an optimum cut-off score of 19.5 points for FIRST-C identifying STID and GSC. Reliability analysis indicated that Cronbach′s α coefficient was 0.873 and Spearman-Brown split-half reliability was 0.864, with item and total score correlation coefficient ranging from 0.326 to 0.752. Moreover, there was statistically significant difference between the total scores of FIRST-C at the 3-month retest and those at the initial test(t=5.440, P<0.001). Conclusion The FIRST-C demonstrates better psychometric characteristics for assessing sleep reactivity in patients with STID. |
