Feeling Good, Living Life: Evaluation of Psychometric Properties of the Slovak Version in Children Age 8–11 Years

The aim of this study was to psychometrically evaluate the feeling good, living life questionnaire (FGLL) in Slovak children. Specifically, we aimed to assess the internal consistency and several proofs of the measure of the construct validity. The sample consisted of 454 children in grades 3–5, age 8–11 (mean age = 9.85, 48% boys) from state (N = 256) and Catholic school (N = 198). The internal consistency of the FGLL was assessed using Cronbach’s alpha (α). Confirmatory factor analysis (CFA), correlation analysis (Pearson and Spearman r) and nonparametric Mann–Whitney U test were used to verify multiple proofs of the construct validity. The values of Cronbach’s alpha, apart from the scale “Relationship with Self,” show satisfactory internal consistency (α = 0.68–0.84). The results of the CFA support factor structure of both parts of the Slovak version of FGLL. Further proof of the construct validity was provided by significant interscale correlations. Depending on the type of school, there were no significant differences in the scale “Relationship with God.” Slovak version of FGLL is suitable for measuring spirituality or spiritual well-being of children age 8–11 years.
