A preliminary empirical evaluation of KooLKIDS: A school-based program to reduce early onset antisocial behaviour in children

Background The aim of the present study was to conduct a preliminary empirical evaluation of the KooLKIDS program, a school-based intervention that utilises a combination of whole-of-class and individual sessions for young children with early onset antisocial behaviour.Method Trained facilitators delivered the 13-session program to a completer sample of 49 primary school-aged children (7–11 years) with early onset antisocial behaviour (42 boys and seven girls suspended from school or at risk for suspension) and their peers.Results Analyses showed significant postintervention reductions on many outcome variables, including teacher and child self-rated aggression and antisocial traits. Significant improvements were also found on measures of emotional intensity and peer acceptance. Acceptability and feasibility data were promising.Conclusion KooLKIDS has the potential for redirecting the trajectory of antisocial behaviour towards more positive social and emotional outcomes for these at-risk children.
