This study aimed to develop and validate an Arabic version of the Prejudice in Mental Illness (PPMI) scale that is more culturally relevant and suitable for our society, while also being compatible with the Arabic language. A total of 145 Pharm.D. and medical students, men and women participated in this research, they used both the translated and the original version of the PPMI scale. The Arabic translated version demonstrated satisfactory internal consistency, with Cranach’s alphas of .84 for fear/avoidance, .65 for malevolence, .68 for authoritarianism, .76 for unpredictability, and an overall scale score of .80, all were statistically significant (P < .001). Test-retest reliability was assessed through interclass correlation coefficients (ICC), revealing values of .79 for fear/avoidance, .67 for authoritarianism, .45 for malevolence, .77 for unpredictability, and .74 for the total items (P < .001). Furthermore, factor analysis using Varimax rotation showed that items 11 and 17 loaded on Component 2 with malevolence items, while item 28 loaded on Component 4 with authoritarianism. The Arabic PPMI version demonstrated robust reliability and validity, supporting its use in KSA, including a test-retest correlation of r = .74 (P < .001) and a Cranach’s alpha of 0.81 for the overall scale.
