To test the feasibility, reliability, and validity of the Satisfaction with Life Scale (SWLS) in an online format in university students from a low-income region.
This was a psychometric study, involving a study of reliability (n = 117) and validity (n = 195) in university students from a region with a Gini index of 0.56. The scale was applied at two time points with an interval of 2 weeks. This scale measures satisfaction with life based on five statements and responses ranging from 1 to 7 (strongly disagree to strongly agree). We conducted the reliability assessment using temporal stability and internal consistency and construct validity assessment by internal structure solution.
All SWLS items showed acceptable (rho > 0.30) and significant (p < 0.05) temporal stability and acceptable internal consistency (alpha > 0.70). In construct validity (internal structure), we identified a factor with an explained variance of 59.0% in the exploratory factor analysis. Additionally, in the confirmatory factor analysis, we identified a one-factor structure solution for SWLS with an acceptable model fitting (chi-square/degrees of freedom [X/df] = 6.53; Tucker-Lewis Index [TLI] = 0.991; Comparative Fit Index [CFI] = 0.996; root mean square error of approximation [RMSEA] = 0.040; standardized root mean-squared residual [SRMR] = 0.026).
The Satisfaction with Life Scale, in the online format, is a reliable and valid tool for university students in a low-income context.
测试生活满意度量表（SWLS）在线版在低收入地区大学生中的可行性、可靠性和有效性。
这是一项心理测量学研究，涉及对基尼系数为0.56地区的大学生进行可靠性研究（n = 117）和有效性研究（n = 195）。该量表在两个时间点应用，间隔为2周。该量表基于五个陈述和从1到7的回答（从强烈不同意到强烈同意）来衡量生活满意度。我们使用时间稳定性和内部一致性进行可靠性评估，并通过内部结构解决方案进行结构效度评估。
所有SWLS项目均显示出可接受的（rho > 0.30）且显著的（p < 0.05）时间稳定性以及可接受的内部一致性（alpha > 0.70）。在结构效度（内部结构）方面，我们在探索性因素分析中确定了一个解释方差为59.0%的因素。此外，在验证性因素分析中，我们确定了SWLS的单因素结构解决方案，其模型拟合度可接受（卡方/自由度[X/df] = 6.53；塔克-刘易斯指数[TLI] = 0.991；比较拟合指数[CFI] = 0.996；近似均方根误差[RMSEA] = 0.040；标准化均方根残差[SRMR] = 0.026）。
