Job satisfaction is related to better physical and mental health, as well as to factors specifically related to work. In this context, the measurement of work satisfaction is important for organizations that profess an interest in engaged and satisfied workers. Therefore, this study aims to examine the psychometric properties of the Satisfaction with Job Life Scale (SWJLS) in Portuguese workers by combining the procedures of the Classical Test Theory (CTT) and the Item Response Theory (IRT). Specifically, internal structure of the scale was studied, its reliability (consistency), correlations with other measures of wellbeing (life satisfaction, loneliness, emotional wellbeing at work, and job satisfaction) were also estimated, and finally, the sacle waqs tested for gender measurement invariance. Participants were 404 workers, 61% women and 39% men, aged between 18 and 64 years (M = 36.85; SD = 14.50). Confirmatory Factor Analysis indicated that the one-dimensional model of the SWJLS was adequate (Robust χ(5) = 9.89, p = .078; CFI = .993; RMSEA = .049, 90% CI [.000 - .094]; SRMR = .011.) and had good internal consistency (ω = .947, 95% CI [.936, 956]; α = .947, 95% CI [.935, .955]). Subsequent analyses revealed that the scores of the SWJLS were related to other measures of job satisfaction ( = .742), job-related emotional well-being ( = .628), satisfaction with life ( = .808) and loneliness ( = -.455). Factorial invariance suggests that the structure of the SWJLS measures the same construct (satisfaction with work-life) in both female and male workers. Moreover, IRT analysis suggests that higher levels of work-life satisfaction are needed to choose the upper response options, while a very low level of work-life satisfaction is required to increase the likelihood of choosing the lower response options. In this sense, the SWJLS is useful and reliable, especially for identifying people with low levels of job satisfaction. These findings support the validity of the SWJLS and indicate that the Portuguese version is a brief instrument with good psychometric characteristics for measuring work-life satisfaction.
工作满意度与更好的身心健康以及与工作具体相关的因素有关。在这种背景下，工作满意度的测量对于那些宣称对敬业且满意的员工感兴趣的组织来说很重要。因此，本研究旨在通过结合经典测验理论（CTT）和项目反应理论（IRT）的程序，检验葡萄牙工人工作生活满意度量表（SWJLS）的心理测量特性。具体而言，研究了该量表的内部结构，估计了其信度（一致性）、与其他幸福感测量指标（生活满意度、孤独感、工作中的情绪幸福感和工作满意度）的相关性，最后，对该量表进行了性别测量不变性检验。参与者为404名工人，其中61%为女性，39%为男性，年龄在18至64岁之间（M = 36.85；SD = 14.50）。验证性因素分析表明，SWJLS的一维模型是合适的（稳健χ(5) = 9.89，p = 0.078；CFI = 0.993；RMSEA = 0.049，90%置信区间[0.000 - 0.094]；SRMR = 0.011），并且具有良好的内部一致性（ω = 0.947，95%置信区间[0.936, 0.956]；α = 0.947，95%置信区间[0.935, 0.955]）。随后的分析表明，SWJLS的得分与其他工作满意度测量指标（ = 0.742）、与工作相关的情绪幸福感（ = 0.628）、生活满意度（ = 0.808）和孤独感（ = -0.455）相关。因素不变性表明，SWJLS的结构在女性和男性工人中测量的是相同的构念（工作生活满意度）。此外，IRT分析表明，选择较高的反应选项需要更高水平的工作生活满意度，而选择较低的反应选项则需要极低水平的工作生活满意度。从这个意义上说，SWJLS是有用且可靠的，特别是对于识别工作满意度较低的人。这些发现支持了SWJLS的有效性，并表明葡萄牙语版本是一种具有良好心理测量特性的简短工具，用于测量工作生活满意度。
