title: Development of a Japanese version of the Positive and Negative Affect Schedule for Children.
abstract: In this paper, the Positive and Negative Affect Schedule for Children originally developed in 1999 by Laurent, et al. was adapted for use in Japan. In Study 1, a total of 763 children in Grades 4 to 6 completed this Schedule, and 103 of them completed it again about three months later. Principal factor analysis with promax rotation identified two factors, positive and negative affect, in the Japanese version, whose alphas (over .80) and test-retest correlations (over .50) were sufficient to indicate internal consistency and stability over time. In Study 2, a total of 328 children completed the Japanese version, the Depression Self-rating Scale for Children, and the Trait Form of the State-Trait Anxiety Inventory for Children. Intercorrelations showed convergent and discriminant validity using these self-report measures of depression and anxiety. Overall these data support the reliability and validity of this Japanese version.
