The Role of Intolerance of Uncertainty and Religiousness in Schizotypal Personality and Life Satisfaction: A Cross-Sectional Study.

Intolerance of uncertainty is an important trans-diagnostic determinant of mental disorders. It is related to psychotic symptoms and religiousness. Religiousness is related to schizotypal personality and wellbeing. Therefore, in a cross-sectional study, we studied the effects of intolerance of uncertainty and religiousness on schizotypal personality and the schizotypal personality-mediated effects of intolerance of uncertainty and religiousness on life satisfaction. On a sample of 734 college students (age,  = 20.3,  = 3.48), intolerance of uncertainty, religiousness, life satisfaction, and schizotypal personality were measured through paper-pencil questionnaires. The results showed that intolerance of uncertainty had positive (direct) relationships with all schizotypal personality dimensions. However, intolerance of uncertainty had positive (mediated by ideas of reference and magical thinking) and negative (mediated by eccentric behavior) indirect effects on life satisfaction. Religiousness had direct as well as indirect (mediated by eccentric behavior) positive effects on life satisfaction. However, the behaving (mediated by ideas of reference) and belonging (mediated by magical thinking) sub-dimensions of religiousness had some indirect negative effects on life satisfaction. Thus, the present study shows that intolerance of uncertainty is an important contributor to psychotic proneness. Religiousness is largely health-enhancing. Moreover, there is a nuanced pattern of interactional relationship between intolerance of uncertainty, religiousness, schizotypal personality, and life satisfaction. We have discussed the theoretical and applied implications of the findings.
