Abstract
The present study is intended to offer stronger grounds to Snyder & Fromkin's assertion for construct validity of the Need For Uniqueness Scale (1977, 1980). Four hundred and eighty-six college students filled out a Japanese version of the Need For Uniqueness Scale along with some other questionnaires related to the hypothesized disposition of uniqueness seeking. The present version of the scale showed (a) a high internal consistency (α=.795), (b) a high testretest reliability (γ=.876), and (c) an extremely low correlation with approval motive (γ=-.063), thus fulfilling the essentially desirable characteristics of a psychological scale. Advocation of construct validity of the scale was justified by (a) a significant positive relation between the scale score and a uniqueness preference score based on the subjects' preference for a professional baseball team, favorite type of novels, taste for jewels, preferred leisure activities, etc., and (b) a significant negative relation of the subjects' number of Rorschach popular responses to the scale score. Implication of these evidences is discussed with regard to the evaluation of need for uniqueness as a dispositional trait. A reproduction of the exact wording and format of the items and a circumstantial report of the scale score distribution are also presented.
