A training program by teachers for parents of school children who were creating problems at school was investigated. Parents (N=10 couples) rated their child's at-home behavior by means of a checklist, participated in group sessions led by the teachers with a focus on means for dealing with student behavioral problems, and then rated their child's at-home behavior after the completion of the group sessions. The control group of six parental couples completed only the behavior checklists at the beginning and end of the final grading period of the school year. A correlated T-test between parental ratings before and after group involvement indicated significant subjective positive changes by the parents, while no significant changes occurred among the control group. Additionally, teachers rated children whose parents attended the group sessions more positively in overall classroom behaviors whereas control group children's ratings were unchanged. (Author/HLM)
