This dissertation study investigated the impact of brief teacher consultation on teachers' implementation fidelity, quality of implementation, and student responsiveness during the "Strong Kids" social-emotional learning curriculum. Additional outcome measures included teachers' self-efficacy and teachers' perceptions of social validity of the "Strong Kids" program. Participants included six teachers, three of whom were randomly assigned to the treatment group and three of whom were randomly assigned to the control group. Teachers in the treatment group received brief performance feedback consultation for six out of the twelve "Strong Kids" lessons; whereas, teachers in the control group did not receive consultation, but instead were given a frequently asked questions sheet that provided them with general information about the curriculum. Results of the study indicated an increase in implementation fidelity for the teachers receiving performance feedback consultation and a decrease in implementation fidelity for the teachers who did not receive performance feedback. The data did not indicate any substantial effects for the consultation group teachers with respect to quality of implementation or student responsiveness. Overall, teachers in both the treatment and control groups had positive attitudes toward social-emotional learning and the curriculum. Both groups of teachers also reported similar negative attitudes regarding the curriculum. For example, both groups of teachers felt that the lessons took too long to implement within a given class period. Implications of this study for future research and practice are discussed.
