Abstract
This study developed a teacher-rated social skills scale for preschool children. Classroom teachers (N=100) were asked to rate the social skills of preschool children in their classes. Factor analysis of the data obtained for 1,493 preschoolers revealed three factors: assertion skills, cooperation skills, and self-control skills. The reliability of the scale was examined using Cronbach's α and the test-retest method, and was verified by satisfactorily high coefficients. In addition, the construct validity of the scale was supported by the negative correlation of the scores of a social-skills scale with the scores of a problem-behaviors scale.
