Abstract
This study examined the effects of positive behavior support (PBS)-based childcare in a nursery class that includes children with neurodevelopmental disorders. We investigated whether class-wide PBS promoted desirable behaviors among children. In a 5-year-old class where children’s undesirable behaviors were often observed during snack preparation, we implemented PBS-based intervention to encourage children to behave in desirable ways. The time required for the preparation was shortened and positive interactions among children were enhanced, indicating that the PBS-based intervention promoted desirable behavior and prosocial behavior. These findings suggest the effectiveness of this approach, particularly in improving snack preparation behavior that requires special consideration.
