Validation and psychometric evaluation of the Arabic version of the prejudice towards people with mental illness (PPMI) scale

Sami S. Alharthi, Hadeel H. Altalhi, Ahmed S. Alzahrani

We set out to generate a validated Arabic version of the Prejudice towards Mental Illness scale cases that are and easier and more compatible with our society as it is compatible with our language and culture. One hundred forty-five medical and Pharm.D. Students of both genders participated in this study using both the original and translated versions of the PPMI scale. The Arabic PPMI scale showed acceptable internal consistency, with the following Cronbach’s alphas: fear/avoidance (.84), malevolence (.65), authoritarianism (.68), unpredictability (.76), and a total-scale score of (.8); all of which were significant (p< .001). Test-retest reliability of the PPMI Arabic version was shown using interclass correlation coefficient (ICC) as follows: ICC = .79 for fear/avoidance, .45 for malevolence, .67 for authoritarianism, .77 for unpredictability, and .74 for all items (p < .001). Finally, Varimax rotation was performed and indicated that Items 11 and 17 had loaded on Component 2, with the malevolence items. 28 loaded on Component 4, together with authoritarianism. The Arabic version of the PPMI clarified acceptable reliability and validity results for using in Saudi Arabia, including test–retest analysis of the overall items (r = .74, p< .001, Cronbach's alpha = 0.81).
