  1. Model I = baseline model without modifications; Model II = model with cross-loadings for item 7 and 8; Model III = model with cross-loadings for item 7 and 8 and collapsed response categories (category 2 and 3)
  2. Goodness-of-fit indices for excellent model fit: RMSEA root mean square error of approximation (≤ 0.06), CFI comparative fit index (≥ 0.95), TLI Tucker-Lewis index (≥ 0.95)
