This study examined the differences among social skills and problem behaviors of disabled (n = 22) and nondisabled (n = 27) preschoolers on Social Skills Rating System-Teacher Version. Significant differences were found between the two groups on all measures of social skills and all but one measure (internalizing problems) of problem behaviors. Also, correlations with a measure of social competence and 8 teachers' ratings strongly supported the validity of this measure of social skills for preschool children. Implications for designing early intervention programs are discussed.
