This webinar addresses what constitutes an “evidence-based treatment (EBT)” and an “evidence-based practice (EBP),” the difference between efficacy and effectiveness, and what we need to know about them in order to make more informed decisions in selecting EBTs and EBPs that are best suited to our agencies or clinics. Major concepts underlying EBTs will be discussed: 1) treatment integrity/fidelity, 2) external validity/generalizability, 3) operational definitions, and 4) statistically vs. clinically significant results. Factors related to the application of EBTs/EBP to culturally diverse populations will be examined: 1) samples on which EBTs are based, 2) use of ethnic vs. cultural groups, 3) “generic” vs. culturally specific EBTs, 4) cultural content vs. cultural context, 5) advantages and disadvantages of culturally adapted EBT, and 6) sustainability of EBTs/EBP. The webinar will present the contribution of meta-analyses to EBTs, the EBTs in the context of the factors that contribute to change in interventions (e.g., therapy relationship and client contribution), limitations of EBTs, common elements of EBTs, and the role of politics, power, and privilege in the scientific study of treatment outcome. Processual issues critical to moving from EBTs to EBP will be discussed. The webinar will describe alternative approaches to EBTs/EBP, such as those grounded on practice-based evidence and community-based evidence or those considered “promising practices,” and alternative concepts to external validity (generalizability), such as ecological validity and social validity.
