ユニークネス尺度の作成と信頼性・妥当性の検討 The development and validation of the uniqueness scale
Need for uniqueness is defined by Snyder & Fromkin (1977) as a positive striving for different-ness relative to other people, and discriminated from abnormality and deviance on its positive connotations. Five studies were conducted to construct the Uniqueness Scale considering positive connotations of need for uniqueness and to examine the reliability and validity of the scale. In study 1,305 university students completed the Uniqueness Scale along with some other personality scales. Scores on the Uniqueness Scale showed a high internal consistency (α=.794). The Uniqueness Scale score was significantly and positively correlated with the measures of self-esteem (γ=.329), private self-consiousness (γ=.189) and Snyder & Fromkin's need for uniqueness scale (γ=.344). Discriminant validation data meet the normal psychometric criteria expected of an individual-difference measure. In other four studies, the uniqueness attributes study, the self-concept study, self-concept factor study and the emotional reaction study, the results supported the validity of this new scale as a measure of need for uniqueness.
