More Than Afterthoughts and Details: Maintenance and Booster Effects as Critical Elements of Intervention Research

The set of studies in this special section bring into relief the importance of due attention to maintenance effects and use of boosters as critical components of intervention planning and evaluation, requiring theoretical and analytic forethought and direction. While some trends can be identified across these included reports and the other few studies of boosters in child psychopathology intervention, the main implication of work to date is to highlight the need to consider maintenance and booster effects analyses as more than afterthoughts of technical interest primarily. In addition, this collection of studies includes treatment and prevention efforts focused on a shared topic, which is rare in child psychopathology topical collections. This juxtaposition helps illuminate some of the many considerations that could influence how maintenance effects and booster contributions might be tested. It is hoped that further work will occur that builds on these exemplary efforts.
