| Summary: | Background This study examined the psychometric properties of the Arabic version of the Mental Retardation Attitude Inventory-Revised (MRAI-R) scale. Method: Data were collected from 455 undergraduate college students (214 female, 241 male). A statistical analysis was conducted using confirmatory factor analysis (CFA), exploratory factor analysis (EFA), and Cronbach’s alpha. Results: The internal consistency of the MRAI-R scale overall was good (0.76). However, it was less than 0.7 for the four subscales. CFA results for the 36-item scale indicated that the observed data did not support the four-factors model. However, separating the scale into two scales based on the phrasing type of items (positively phrased or negatively phrased) resulted in an acceptable fit for the model. Conclusion: Replication of this research with a different sample from Saudi Arabia is required to confirm the results of this study. Any future iteration of this study should consider the rephrasing of some items.
