Comments

  

Mirpuri and Urdu best fit for items 1–5

 

Several other models were a better fit for Mirpuri and Urdu

 

The full item set (15–21) fit all groups best except Urdu

 

24–27 fit all groups best except Mirpuri which was poor (CFI = 0.701, RMSEA = 0.163)

  1. Adequate fit statistics were considered to be CFI ≥0.95, RMSEA ≤0.08 and SRMR ≤0.06, bolded fit indices indicate less than satisfactory fit, * severe model estimation difficulties.
