"The present study examines the effectiveness of a social skills therapy program for school-age children ages 11 through 18. The program uses art therapy and cognitive-behavioral techniques in a group therapy format to broaden and deepen the state-of-the-art techniques used in helping children with social developmental disorders to improve their social skills. Pre- and posttest instruments were distributed to parents and teachers in October and May of the 2004—2005 school year. Scores revealed a significant improvement in assertion scores, coupled with decreased internalizing behaviors, hyperactivity scores, and problem behavior scores in the students. Implications for social work and policy are discussed."
