This study was conducted with four subjects with multiple behavior problems (noncompliance, nonattending, and poor academic performance). The subjects ranged in age from 3-years 1-month to 5-years 6-months. Treatment occurred in a classroom setting using an interacting elements design counterbalanced across subjects. The results indicated the existence of behavioral covariations and treatment side-effects. The implications of these findings for research on generalization effects and treatment approaches to children with multiple behavioral problems was discussed.
