The purpose of this study is to construct the Multidimensional Optimism Assessment Inventory (MOAI) and to examine its reliability and validity. Prior to the investigation, three subconcepts of optimism (optimistic expectancy, optimistic evaluation, and easy switching) were hypothesized and 46 items (optimistic expectancy; 24 items, optimistic evaluation; 16 items and easy switching; 6 items) were selected. Four hundred and sixty undergraduates were administrated MOAI and other scales. Exploratory factor analysis yielded 6 factors, so 6 subscales were constructed (optimistic evaluation for ability, easy switching, optimistic expectancy for external resources, optimistic expectancy for luck, groundless optimism and optimistic expectancy for future). Except for groundless optimism subscale (α=.56), Cronbach's alpha coefficients of five subscales were moderately high (they were greater than .65). The correlations between the score of MOAI and other scales supported hypothesized relations. Taken together, the result confirmed the reliability and validity of MOAI, at least partially.
