Abstract

The Satisfaction with Family Life Scale (SWFLS) is a measure of a person’s satisfaction with their family life as a whole that has been used in different cultural contexts. However, its internal structure and factorial invariance have not been investigated simultaneously in culturally different samples from America and Europe. The current study aims to evaluate the internal structure and factorial invariance of the SWLFS in adolescents from Peru and Portugal, through a multi-group confirmatory factor analysis. The study was conducted on 439 adolescents from Peru (N = 232; Age_average = 15.50, S.D. = 0.65) and Portugal (N = 207; Age_average = 16.16, S.D. = 0.81). First, the confirmatory factorial analysis for each group was carried out, followed by the multi-group confirmatory factorial analyses. Results indicated that the one-factor structure of the SWLFS presents a good adjustment to the data, in addition to an adequate internal consistency. Moreover, the presence of configural, metric, scalar and strict invariance is demonstrated across culturally different samples. The SWFLS is a brief and valid measure of satisfaction with family life that is useful for intercultural comparisons between samples of adolescents from Peru and Portugal.

摘要

家庭生活满意度量表 (SWFLS) 是衡量一个人对其家庭生活整体满意度的衡量标准，该量表已在不同的文化背景下使用。然而，其内部结构和因子不变性尚未在来自美国和欧洲的文化不同的样本中同时进行研究。本研究旨在通过多组验证性因子分析评估秘鲁和葡萄牙青少年 SWLFS 的内部结构和因子不变性。该研究对来自秘鲁（N  = 232；_平均年龄= 15.50，SD = 0.65）和葡萄牙（N  = 207；_{平均年龄）的 439 名青少年进行}= 16.16，标准差 = 0.81）。首先对各组进行验证性因子分析，然后进行多组验证性因子分析。结果表明，SWLFS 的单因素结构除了具有足够的内部一致性外，还对数据进行了很好的调整。此外，在不同文化的样本中证明了配置、度量、标量和严格不变性的存在。SWFLS 是一种简短而有效的家庭生活满意度衡量标准，可用于秘鲁和葡萄牙青少年样本之间的跨文化比较。
