Psychometric properties of the Satisfaction with Life Scale in Brazilian Para athletes

Abstract

The aim of the present study was to evaluate the psychometric properties of the Satisfaction with Life Scale (SWLS) for Brazilian athletes, as well as its factor structure, reliability, and invariance. Three hundred nine Para athletes recruited by both sex were evaluated online using sociodemographic, sex, and the SWLS version by Gouveia et al. (2009). Confirmatory factor analysis was used to evaluate the one-dimensional structure of the scale using the Robust Diagonally Weighted Least Squares (RDWLS) extraction method. The SWLS one-dimensional model showed a good fit to the data (χ2 = 1.906 / df = 5; p = 0.86; CFI = 1.000; SRMR = 0.019; RMSEA = 0.000 [90% CI: 0.000 – 0.042] and adequate internal Omega of McDonald's (0.8) and good composite reliability (0.88). The Brazilian version of the SWLS in Paralympic athletes showed satisfactory psychometric properties and can be used to measure life satisfaction in the Paralympic context.
