In
1998, Eyberg and colleagues conducted a review of the literature of booster sessions and other maintenance strategies for enhancing the long-term maintenance of treatment effects for parent training programs. This timely review concluded with a call for more studies examining: 1) the long-term maintenance of treatment effects, and 2) the need to test the incremental benefit of booster sessions using randomized control group designs. Ten years later, an updated review by Eyberg and colleagues (
2008) of treatments for disruptive behavior reported that most of the interventions included in that review had shown maintenance of treatment gains for at least a year after treatment had ended, but that many of the follow-up studies included designs that were only modestly rigorous. They suggested the need to explore alternative designs that would permit careful evaluation of disruptive behavior over time to document more rigorously maintenance effects. This special series is a step towards providing a response to this call. …
