The Application of a Three-Tier Model of Intervention to Parent Training.

A three-tier intervention system was designed for use with parents with preschool children with developmental disabilities to modify parent-child interactions. A single-subject changing-conditions design was used to examine the utility of a three-tier intervention system in reducing negative parenting strategies, increasing positive parenting strategies, and reducing child behavior problems in parent-child dyads (n = 8). The three intervention tiers consisted of (a) self-administered reading material, (b) group training, and (c) individualized video feedback sessions. Parental behavior was observed to determine continuation or termination of intervention. Results support the utility of a tiered model of intervention to maximize treatment outcomes and increase efficiency by minimizing the need for more costly time-intensive interventions for participants who may not require them.
