Note. CFA, confirmatory factor analysis; MHC‐SF, Mental Health Continuum‐Short Form; SB χ 2, Satorra‐Bentler scaled chi‐square (smaller values indicate better fit); df, degrees of freedom; NCP, estimated noncentrality parameter (smaller values indicate better fit); AIC, Akaike's information criterion (smaller values indicate better fit); RMSEA, root mean square error of approximation (good fit ≤ 0.05; acceptable fit ≤ 0.08); CFI, comparative fit index (good fit ≥ 0.97; acceptable fit ≥ 0.95); SRMR, standardized root mean square residual (good fit ≤ 0.05; acceptable fit ≤ 0.10); GFI, goodness of fit index (good fit ≥ 0.95; acceptable fit ≥ 0.90); AGFI, adjusted goodness of fit index (good fit ≥ 0.90; acceptable fit ≥ 0.85).
