The Short Form version of the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q-SF) was designed to measure patients' subjective experience of enjoyment and satisfaction. However, it had not yet been validated for Chinese societies. This paper reports on the validation of the Chinese version of the Q-LES-Q-SF among primary care patients in Taiwan.
The study included adult patients in primary care clinics. The participants completed the Q-LES-Q-SF, the Patient Health Questionnaire, and the Short Form Health Survey. After that, the trained researchers interviewed the patients using the mood module of the Schedules for Clinical Assessment in Neuropsychiatry and the 17-item Hamilton Rating Scale for Depression. A subsample of participants was reassessed with Q-LES-Q-SF within a 2-week interval.
A total of 1,482 patients completed the Q-LES-Q-SF. The content validity was good, with no significant floor/ceiling effect. The internal consistency of the Q-LES-Q-SF proved to be substantial as well as the test-retest reliability. The factor structure was examined by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The EFA yielded a 2-factor structure, which was confirmed by a CFA with acceptable fit indices. Known-group validity of the Q-LES-Q-SF was satisfactory in distinguishing patients with and without depression, according to hierarchical regression analyses. Evidence of concurrent validity was provided for the Q-LES-Q-SF, and its two subscales identified significant correlations with other measures.
The Chinese Q-LES-Q-SF was shown to have adequate validity and reliability. It may be a useful tool to measure patients' quality of life in Chinese societies.
生活满意度和享受问卷（Q-LES-Q-SF）的简式版本旨在衡量患者的享受和满意度的主观体验。然而，它尚未在中文社会中得到验证。本文报告了 Q-LES-Q-SF 的中文版本在台湾基层医疗患者中的验证结果。
该研究纳入了基层诊所的成年患者。参与者完成了 Q-LES-Q-SF、患者健康问卷和健康调查简表。之后，经过培训的研究人员使用精神科临床评估时间表的情绪模块和 17 项汉密尔顿抑郁评定量表对患者进行访谈。部分参与者在两周的间隔内重新评估了 Q-LES-Q-SF。
共有 1482 名患者完成了 Q-LES-Q-SF。内容效度良好，无显著地板/天花板效应。Q-LES-Q-SF 的内部一致性证明是充分的，测试-重测信度也很好。通过探索性因子分析（EFA）和验证性因子分析（CFA）来检验因子结构。EFA 得出了 2 个因子结构，CFA 也证实了具有可接受的拟合指数的因子结构。根据层次回归分析，Q-LES-Q-SF 的区分有和无抑郁患者的效标效度令人满意。Q-LES-Q-SF 的同时效度证据充足，其两个分量表与其他测量工具显著相关。
中文 Q-LES-Q-SF 具有充分的有效性和可靠性。它可能是一种在中国社会中衡量患者生活质量的有用工具。
