Satisfaction With Family Life Scale: Adaptação e Evidências de Validade e Precisão

Abstract

Satisfaction with Family Life Scale: Adaptation and Evidence of Validity and Reliability This study aimed to adapt the Satisfaction with Family Life Scale (SWFLS) to Brazilian Portuguese, supported by factorial validity and internal consistency evidence. Study 1 included 216 respondents, aged between 18 and 92 years (M=38.43; SD=15.90), of whom 71.6% were female, who answered to the SWFLS and sociodemographic questions. The exploratory factorial analysis indicated a one-factor structure with 70% of Total Variance Explained and a Cronbach's alpha of .89. In Study 2, the sample was composed of 214 respondents, aged between 18 and 77 years (M=29.8; SD=11.65), the majority female (69.6%), who answered the same instruments as Study 1. The Confirmatory Factor Analysis confirmed a single-factor structure, presenting a Cronbach's alpha of .89. It was concluded that the instrument has adequate psychometric properties, representing a valuable tool for use in future research with families.
