The Work-Related Quality of Life Scale (WRQLS) was developed by Van Laar et al. The Thai version was developed and could be completed in 13.4 min on average with some items having a factor loading of less than 0.4. The aims of this study were (a) to develop a brief Thai version of the WRQLS (brief THWRQLS), and (b) to assess its validity and reliability. A descriptive correlation study was performed with the components of THWRQLS selected based on statistical and judgmental criteria. The statistical criteria were developed using secondary data from 320 physicians identifying discrimination, internal consistency and exploratory factor analysis (EFA). The judgmental criteria included content validity and agreement by five experts. The web-based brief THWRQLS was then used by 250 health personnel, and confirmatory factor analysis (CFA) was conducted and internal consistency assessed. The brief THWRQLS consisted of seven dimensions, encompassing 25 of the original 32 items. The CFA revealed that most of the standardized factor loadings were greater than 0.5. The goodness of fit was 268.772 (p < 0.01), the comparative fit index was 0.971, the root mean square error of approximation was 0.039, and the standardized root mean square residual was 0.049. The Cronbach's alpha coefficient of the scale was 0.94, and almost all dimensions were greater than 0.7 except for that of "stress at work," which was 0.53. In conclusion, the brief THWRQLS appeared to be valid, and the reliability was acceptable, except in the dimension of "stress at work."
工作相关生活质量量表（WRQLS）由 Van Laar 等人开发。该量表的泰文版本由泰国开发，可以在平均 13.4 分钟内完成，其中一些项目的因子负荷小于 0.4。本研究的目的是：（a）开发工作相关生活质量量表的简短泰文版本（简短 THWRQLS）；（b）评估其有效性和可靠性。采用基于统计和判断标准选择的 THWRQLS 组成部分进行描述性相关性研究。统计标准是使用来自 320 名医生的二级数据制定的，这些数据用于确定鉴别力、内部一致性和探索性因子分析（EFA）。判断标准包括内容有效性和五位专家的一致性。然后，250 名卫生人员使用基于网络的简短 THWRQLS，进行验证性因子分析（CFA）和内部一致性评估。简短 THWRQLS 由七个维度组成，包含原始 32 个项目中的 25 个项目。CFA 显示，大多数标准化因子负荷均大于 0.5。拟合优度为 268.772（p<0.01），比较拟合指数为 0.971，均方根误差近似值为 0.039，标准化均方根残差为 0.049。量表的 Cronbach's alpha 系数为 0.94，除“工作压力”维度为 0.53 外，几乎所有维度均大于 0.7。总之，简短 THWRQLS 似乎具有有效性，且可靠性可接受，除了“工作压力”维度外。
