ABSTRACT: The researchers validated the intrinsic motivation sub-scale of the Academic Motivation Scale AMS-28 college version developed by Vallerand et al. (1992) in the Indian context. 282 IInd year engineering students (50 girls and 220 boys) belonging from Lovely Professional University, Phagwara, Punjab and Osmania University, Hyderabad, Telangana, were the sample subjects of the study. The three dimensions of academic intrinsic motivation, namely, Intrinsic motivation to know, intrinsic motivation towards accomplishments and intrinsic motivation to experience stimulation, showed acceptable internal consistency reliability, with their Cronbach’s alpha being 0.648, 0.641 and 0.691 respectively. The ordinal alpha and ordinal omega estimates of the sub-scales were 0.65, 0.66, 0.72 and 0.67, 0.7, 0.76 respectively using the Psych function of R software. The goodness of fit of the model was tested using SPSS AMOS Ver. 23 and the estimands like CMIN/DF, TLI, CFI and RMSEA had their estimates satisfying the benchmarks values except RMR. The results indicated good psychometrics of the academic intrinsic motivation sub-scale of AMS-28 in the Indian context.
