ABSTRACT: COVID-19 pandemic's mental health impact on Arab countries is under-researched. The goal of this investigation was to study the differential impact of COVID-19 on the mental health of Arab countries. A questionnaire including measures of COVID-19 traumatic stress, PTSD, depression, anxiety, and cumulative stressors and trauma was distributed anonymously online in seven Arab countries (Egypt (N = 255), Kuwait (N = 442), Jordan (N = 216), Saudi Arabia (N = 212, Algeria (N = 110), Iraq and Palestine (N = 139)). We used ANOVA and stepwise regression to analyze the data. For each country, regression, PTSD, depression, and anxiety were dependent variables; we entered in the first-step, gender, age, religion, education, and income. In the second step, we entered "cumulative stressors and traumas." In the third step, we entered COVID-19 traumatic stress. The ANOVA results indicated that the differences in COVID19 traumatic stress, PTSD, depression, and anxiety between the countries were significant. Post-hoc analysis indicated that Egypt is significantly higher than all the other Arab countries in COVID-19 traumatic stress, PTSD, anxiety, and depression. The subsample from Palestine and Iraq had a significantly higher cumulative trauma load than the other Arab countries but did not have higher levels of COVID-19 traumatic stress or PTSD. Stepwise regression indicated that COVID-19 traumatic stress accounted for significant variance above and beyond the variance accounted for by previous cumulative stressors and traumas for anxiety in all countries and PTSD and depression in all countries except for Algeria. We discussed the implications for these results for the urgent mental health needs of Arab countries.
