The effects of child behavior problems on the maintenance of intervention fidelity.

Maintenance of behavior change has been considered a crucial, through largely unrealized, goal of behavioral interventions. One often overlooked factor is that before interventions can be successful and durable, the intervention protocol must be implemented as planned. This study investigated the effects of child behavior problems on the maintenance of intervention fidelity by teachers across two intervention protocols: escape extinction and functional communication training. A high rate of behavior problems during escape extinction appeared to punish teachers' efforts, and fidelity deteriorated. In contrast, there was a low rate of behavior problems during functional communication training. Teachers maintained high protocol fidelity and those sessions were less stressful and more productive. We propose that intervention protocols can be differentiated by the costs associated with implementing them faithfully. Protocols designed to be user friendly will be more likely to produce high fidelity, and therefore, durable intervention gains.
