Worldwide, the Satisfaction With Life Scale (SWLS) has become the most widely used measure of life satisfaction. Recently, an authorized Vietnamese-language version has been introduced. Using a convenience sample comprising community volunteers from Ho Chi Minh City (N = 1073), confirmatory support was found for the cross-national constancy of the one-dimensional structure underlying the SWLS. Corrected item-total polyserial correlations and Omega coefficient were satisfactory. Using multi-group confirmatory factor analysis, configural, metric, and scalar invariance of the SWLS factorial structure were tested by gender, age, marital status, income, and educational level. Strong evidence of scalar invariance was found for gender and education, on which relevant subgroups did not differ in terms of latent means. Partial scalar invariance was found for marital status (item 4 and 5) and income (item 4). Being involved in an intimate relationship or having a higher income were associated with higher latent means. Scalar invariance in relation to age was very poor. Accordingly, caution must be exerted when comparing age groups. A high SWLS score was predictive of good self-rated health. Implications of the findings are briefly discussed.
在全球范围内，生活满意度量表（SWLS）已成为使用最广泛的生活满意度衡量标准。最近，一个经过授权的越南语版本已经推出。使用来自胡志明市的社区志愿者的便利样本（N=1073），验证了 SWLS 背后的一维结构的跨国恒定性。校正后的项目总分偏态相关和 ω 系数是令人满意的。通过多组验证性因素分析，对 SWLS 因子结构的组态、度量和标度不变性进行了检验，检验的因素包括性别、年龄、婚姻状况、收入和教育水平。在性别和教育方面，标度不变性得到了强有力的证据支持，相关亚组在潜在均值方面没有差异。婚姻状况（第 4 项和第 5 项）和收入（第 4 项）方面存在部分标度不变性。参与亲密关系或收入较高与较高的潜在均值有关。与年龄有关的标度不变性很差。因此，在比较年龄组时必须谨慎。SWLS 得分高预示着自我报告的健康状况良好。简要讨论了这些发现的意义。
