Abstract
The validity of teacher ratings of adolescents' social skills was examined in a follow-up study of a cohort sample of 395 students from seventh to ninth grade. The internal consistency of the teacher ratings on Social Skills Rating System (SSRS) was examined at two points in time, and the multidimensionality of the SSRS was confirmed through factor analyses. The findings indicated multi-informant consistency in ratings: teacher ratings consistently covaried with teacher ratings of problem behaviour in the classroom and academic competence, sociometric nominations by peer students, and grade point average in selected school subjects. Teacher ratings also produced construct-relevant group differences, with students referred to psychosocial and educational helping services receiving significantly lower ratings than their nonreferred peers.
