Abstract

Purpose: 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.

Methods: 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.

Results: 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 [X²/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).

Conclusion: The Satisfaction with Life Scale, in the online format, is a reliable and valid tool for university students in a low-income context.

低收入地区大学生在线生活满意度量表的心理测量特性。

目的：在低收入地区的大学生中测试在线形式的生活满意度量表（SWLS）的可行性、可靠性和有效性：这是一项心理测量研究，包括对来自基尼系数为 0.56 的地区的大学生的信度（n = 117）和效度（n = 195）进行研究。该量表在两个时间点使用，间隔为两周。该量表根据五个陈述和 1 到 7（非常不同意到非常同意）的回答来测量对生活的满意度。我们使用时间稳定性和内部一致性进行了信度评估，并使用内部结构解进行了构建效度评估：结果：SWLS 的所有项目均表现出可接受性（rho > 0.30）和显著性（p 0.70）。在构造效度（内部结构）方面，我们在探索性因子分析中确定了一个解释方差为 59.0%的因子。此外，在确认性因素分析中，我们确定了 SWLS 的单因素结构解，模型拟合度可以接受（卡方/自由度[X2/df] = 6.53；塔克-刘易斯指数[TLI] = 0.991；比较拟合指数[CFI] = 0.996；均方根近似误差[RMSEA] = 0.040；标准化均方根残差[SRMR] = 0.026）：结论：在线形式的生活满意度量表对于低收入环境中的大学生来说是一个可靠有效的工具。
