Psychometric Properties and Validation of the Arabic Academic Performance Rating Scale

Aim. To validate the Arabic version of Academic Performance Rating Scale. Method. Translation and test-retest reliability were computed. Exploratory factor analysis and Rasch analysis were conducted to report on the validity. EFA factor structures were evaluated using a Scree plot and the standard multiple criteria included eigenvalue greater than 1. Average measures and step measures were ordered and themean-square outfit statistic for each category was also evaluated. Results. Cronbach's Alpha value of 0.90 was obtained. No differences across category of educational levels were seen (P > 0.05). Patternmatrix analysis revealed items to be significantly correlated with each other with a chi square goodness of fit value 0.02. Results supported the interpretation of adequate fit of items, since the infit ZSTD(1.55-0.46), outfit ZSTD(1.59-0.99), infitMNSQ(0.74-1.47), and outfitMNSQ(0.50-1.37) for the items were within acceptable ranges. Conclusion. Valid and reliable A-APRS-15 can be used in future studies to see its relation with other variables such as general health and oral health.
