This study examined the relationship between worldview, demographic characteristics, and optimism among university students. A sample of 163 university students from two schools completed a self-report survey that included demographic variables, the Worldview Assessment Instrument (WAI, Koltko-Rivera, 1998), and the Revised Life Orientation Test (LOT-R, Scheier, Carver, & Bridges, 1994). Results suggest that worldview may in part vary as a function of ethnicity. Results further support past findings of non-significant differences in worldview across gender and age. Further, results suggest that optimism may vary across marital status, a significant finding when working with non-traditional students. (Contains 3 tables.)
