Psychometric Properties and Validation of the Arabic Academic Performance Rating Scale

Abstract EN

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 the mean-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).

Pattern matrix 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), infit MNSQ (0.74–1.47), and outfit MNSQ (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.
