|Abstract: Potential consumers of applied behavior analytic research findings (e.g., service providers, funding agencies, and government departments) may request information about the extent to which ABA constitutes evidence-based practice for their population of interest. Typically, their requests concern the effectiveness rather than the efficacy of interventions. In 2008, the majority of behavior analysts in New Zealand cooperated to provide a review of the evidence concerning the efficacy of ABA with people with autism spectrum disorders for the Ministries of Health and Education (Mudford et al., 2009). Our methods were based on those of the National Standards Project (National Autism Center, 2009). Although I will review the findings briefly, the main aim of this presentation is to examine the extent to which typical ABA research can contribute to evidence-based practice across a range of populations, and how those contributions could be improved.
