Identifying evidence-based interventions for children and adolescents using the range of possible changes model: A meta-analytic illustration
Publication or External Link
The article discusses a study involving a framework (range of possible changes [RPC] Model) developed and applied to identify patterns in consistent and inconsistent intervention outcomes effects by informant, measurement method, and method of statistical analysis to the meta-analytic study of trials testing two evidence-based interventions for children and adolescents (youth-focused cognitive-behavioral treatment for child anxiety problems; parent-focused behavioral parent training for childhood conduct problems). This article illustrates how findings gleaned from applying the RPC Model allow for unique opportunities for hypothesis generation based on the patterns of consistent outcomes effects. Based on the RPC Model, studies can be closely examined to identify the specific instances in which interventions yield robust effects, and the authors illustrate how examining effects in this way can lead to new understandings of interventions and the outcomes they produce. Findings suggest that researchers can employ previously underutilized patterns of consistencies and inconsistencies in outcomes effects as new resources for identifying evidence-based interventions.
