Hundert and colleagues (1999) found that the Tri-Ministry Study showed mixed effects. Students in the social skills combined with partner reading program (SS/RE) group received better teacher ratings for externalizing problems, compared with students in the comparison group. Students in the Classwide Social Skills Program (SS) group received better parent ratings for externalizing problems, compared with comparison group students. These differences were statistically significant. However, there were no statistically significant differences between students in the SS/RE group, the SS group, the Connections Partner Reading Program (RE) group, and the comparison group in measures of inappropriate classroom behavior and teacher- and parent-rated social skills. Overall, the preponderance of evidence suggests the program did not have the intended impacts on students.
Study 1
Parent-Rated Social Skills
There were no statistically significant differences in parent-rated social skills between students in the any of the three treatment groups (the SS group, SS/RE group, RE group) and the comparison group, at the 5-year follow up.
Teacher-Rated Social Skills
There were no statistically significant differences in teacher-rated social skills between students in the any of the three treatment groups (the SS group, the SS/RE group, the RE group) and the comparison group, at the 5-year follow up.
Teacher-Rated Externalizing Problems
Students in the SS/RE group received better (that is, lower) teacher ratings for externalizing problems, compared with students in the comparison group. This difference was statistically significant. However, there were no statistically significant differences between students in either the SS group or the RE group and the comparison group in teacher-rated externalizing problems, at the 5-year follow up.
Parent-Rated Externalizing Problems
Students in the SS group received better (that is, lower) parent ratings for externalizing problems, compared with comparison group students. This difference was statistically significant. However, there were no statistically significant differences between students in either the SS/RE group or the RE group, and the comparison group in parent-rated externalizing problems, at the 5-year follow up.
Inappropriate Classroom Behavior
Hundert and colleagues (1999) found no statistically significant differences in inappropriate classroom behavior between students in any of the treatment groups (the SS group, the RE group, the SS/RE group), and students in the comparison group, at the 5-year follow up.
