Table 1 The goodness of fit indices used to signify model fitness

From: The roles of emotional intelligence, neuroticism, and academic stress on the relationship between psychological distress and burnout in medical students

Name of category Name of index Level of acceptance
Absolute fita Root mean square of error approximation (RMSEA) less than 0.08
Goodness of fit index (GFI) more than 0.9
Incremental fitb Comparative fit index (CFI) more than 0.9
Tucker-Lewis index (TLI) more than 0.9
Normed fit index (NFI) more than 0.9
Parsimonious fitc Chi-square/degree of freedom (Chisq/df) less than 5
  1. Note.aAbsolute fit: Measures overall goodness of fit for both the structural and measurement models collectively. This type of measure does not make any comparison to a specified null model (incremental fit measure) or adjust for the number of parameters in the estimated model (parsimonious fit measure). bIncremental fit: Measures goodness of fit that compares the current model to a specified “null” (independence) model to determine the degree of improvement over the null model. cParsimonious fit: Measures goodness of fit representing the degree of model fit per estimated coefficient. This measure attempts to correct for any “overfitting” of the model and evaluates the parsimony of the model compared to the goodness of fit
