Research Design & Number of Studies
Six studies evaluating the effectiveness of Incredible Years® Teachers Classroom Management programme were identified. These studies included five group/cluster RCTs, and one quasi experimental study. Two of the six studies were conducted in collaboration with Incredible Years trainers (Baker-Henningham et al, 2012; Hutchings et al, 2013). Ages of children included in the six studies ranged from 3-9 years, however separate data is not available for the 3-5 year age.
Outcomes achieved
Compared to the control group, implementation of the Incredible Years® Teachers Classroom Management programme was associated with the following outcomes:
Child outcomes
- Significant reductions in overall reported difficulties (Ford et al, 2018)
- Significant reduction in target child’s negatives type behaviour towards teacher; significant reduction in classroom and target child’s off task behaviour ; and significant improvement in child compliance (Hutchings et al, 2013)
- Significant improvements in student prosocial behaviour; significantly improved overall social competence; and significantly reduced emotional dysregulation (Reinke, et al, 2018)
- Significant improvement in child behaviours including conduct problems and friendship skills; significant increase in social skills (Baker-Henningham et al, 2012)
- Significant favourable changes in child-teacher relationship. This significant improvement was also seen in internalising and externalising subsample of children (Tveit et al, 2019)
Teacher outcomes
- Significant reduction in teachers negative type behaviour to target children (Hutchings et al, 2013)
- Significant increase in teachers’ self-reported use of positive classroom management strategies, and significant decrease in negative classroom management strategies (Hickey et al, 2017)
