- Recommended goodness of fit indices values demonstrating good model fit: χ2/df ratio close to zero (Bryant & Yarnold, 1995), RMSEA < 0.06, CFI > 0.95 and TLI > 0.9 (Browne, 2014; Hu & Bentler, 1993). Model 0 indicates baseline models without covaried error terms. Model 1 covaried error terms for items 1 + 5; Model 2 covaried error terms for items 3 + 4, and items 3 + 5 (Fig. 2)
