Problem behaviors at the classroom-level and teacher-child interaction quality in Head Start programs: Moderation by age composition

This study explored the link between classroom-level problem behaviors and teacher-child interaction quality in 307 Head Start preschool classrooms. The moderating role of the classroom's age composition (e.g., 3- and 4-year-olds versus 4-year-olds only) also was examined. Using a dataset of 852 3-year-old children and 1114 4-year-old children, classroom-level problem behaviors were operationalized using teacher reports of children's problem behaviors. Results indicated that classroom-level problem behaviors, specifically oppositional/aggressive and internalizing behavior, were associated with lower teacher-child interaction quality (i.e., emotional support, classroom organization, and instructional support). In contrast, classroomlevel hyperactivity was only negatively related to classroom instructional support. Moderation results indicated that high-levels of classroom-level activity were related to lower-levels of teacher-child interaction quality, but for 4-year-old only classrooms. The results of this study have implications for practice and policy.
