Confirmatory Factor Analysis (CFA) indicated a significant (p < 0.001) association of four latent variables with questionnaire structure. The significant (p < 0.001) difference between craving scores in Independent Sample T-tests indicated the construct validity as concurrent validity. No significant difference (p = 0.063) between two deprived states scores and intra-class coefficient (ICC = 0.97), indicated questionnaire reliability.
