Daily routines in the home are typically the most common interactions for children with their siblings and parents. When a child exhibits challenging behavior in these routines, it can cause a strain on the family as well as the child's ability to learn a more appropriate behavior. This study examined the feasibility and potential efficacy of an adapted version of the Prevent-Teach- Reinforce (PTR) intervention with three families of young children with developmental disabilities. The school-based PTR manual was adapted for treatment use in a family context. The study assessed the family adherence to the collaboratively developed PTR intervention, family use of the behavior rating scale, social validity, procedural integrity, and child behavior behaviors during the routines. A multiple-baseline design across children was used to examine the impact of the PTR intervention on child behavior within the routine. Results indicated that the PTR interventions were successful in demonstrating an increase in appropriate behaviors and a decrease in challenging behaviors across children. The results also indicated that parents were able to successfully use the behavior rating scale to measure each child's behavior.
