To explore the associations between religiosity, health, and psychopathology, samples of 460 Kuwaiti and 274 American college students were recruited. Religiosity, pessimism, anxiety, obsession-compulsion, death obsession, and ego-grasping were significantly higher among the Kuwaitis than among their American counterparts. On the other hand, self-ratings of mental health and optimism were significantly higher among the Americans than their Kuwaiti counterparts. Religiosity was significantly and positively associated with ratings of physical health, mental health, and optimism (both countries), and negatively with pessimism, anxiety, suicidal ideation, and ego-grasping (Kuwaitis), and pessimism and suicidal ideation (Americans). A factor analysis of the correlational matrix yielded in both countries two independent factors labeled "Normality vs. psychopathology", and "Religiosity, health, and optimism". Backward multiple regressions revealed that the main predictors of religiosity were mental health, optimism and physical health positively, and obsession-compulsion and ego-grasping negatively in Kuwaitis; and optimism positively and anxiety, and suicidal ideation negatively in Americans. By and large, those who consider themselves as religious were more healthy and optimistic, and obtained lower scores on psychopathology in both countries.
