RMSEA: root-mean-square error of approximation; CFI: comparative fit index, TLI: Tucker–Lewis Index. Satorra–Bentler scaled model fit indices were used, as is recommended for models with non-normal variables and smaller sample sizes. (Boateng et al. 2018)
Thresholds used for good fit: Chi² p > 0.05; (Cabrera-Nguyen 2010) RMSEA ≤ 0.06, (Hu and Bentler 1999) CFI > 0.95, TLI > 0.95 (Schreiber et al. 2006)
