Alertness is an important part of attention which is different from the opposite of sleepiness. This study aimed to translate and assess the measurement properties of the Toronto Hospital Alertness Test (THAT) in Hong Kong Chinese population.
The standard forward-backward translation procedure and cognitive debriefing were conducted to obtain the Chinese THAT. One hundred Chinese adults completed the Chinese THAT, the Center for Epidemiological Studies Depression Scale (CES-D), the Pittsburgh Sleep Quality Index (PSQI), and the Athens Insomnia Scale (AIS) by telephone interviews.
The factorial validity was assessed by confirmatory factor analysis, and the internal reliability was examined by coefficient omega. The two negatively worded items of the THAT had low factor loadings and were removed. One more item was removed based on the modification indices of the eight-item model. The remaining seven-item THAT showed satisfactory unidimensionality with root mean square error of approximation (RMSEA) = 0.06, standardized root mean square residual (SRMR) = 0.08, and comparative fit index (CFI) = 1.00. The coefficient omega of the seven-item Chinese THAT was 0.80 (95% CI: 0.74-0.86). Convergent validity was demonstrated with THAT moderately associated with CES-D (r = - 0.45, P < 0.01), PSQI (r = - 0.40, P < 0.01), and AIS (r = - 0.45, P < 0.01).
The Chinese version of THAT demonstrated acceptable reliability and validity in a Chinese population.
警觉性是注意力的重要组成部分，与困倦相反。本研究旨在翻译并评估多伦多医院警觉性测试（THAT）在香港华人中的测量属性。
采用标准的前后翻译程序和认知反馈来获取中文版的THAT。100名中国成年人通过电话访谈完成了中文版的THAT、流行病学研究中心抑郁量表（CES-D）、匹兹堡睡眠质量指数（PSQI）和雅典失眠量表（AIS）。
通过验证性因素分析评估因素效度，用ω系数检验内部信度。THAT中两个反向计分的条目因素载荷较低，予以删除。根据八项模型的修正指数又删除了一个条目。剩余的七项THAT显示出令人满意的单维度性，近似均方根误差（RMSEA）=0.06，标准化均方根残差（SRMR）=0.08，比较拟合指数（CFI）=1.00。七项中文版THAT的ω系数为0.80（95%CI：0.74-0.86）。THAT与CES-D（r=-0.45，P<0.01）、PSQI（r=-0.40，P<0.01）和AIS（r=-0.45，P<0.01）中度相关，证明了收敛效度。
中文版的THAT在华人人群中显示出可接受的信度和效度。
