  1. Bucks County Autism Support CoalitionWhat is Evidence-Based Practice?Why is it important?

  2. Today’s Goals • Why we rely on science and technology • Defining EBP • Implementing EBP • Identifying EBP • The Future of EBP

  3. My background • As a father • As a clinician • As a teacher • As a researcher • As a program leader

  4. WHY SCIENCE & TECHNOLOGY?How these have improved our lives • The Ghost Map • Brunelleschi’s Dome • The Brooklyn Bridge • EIBI

  5. WHY SCIENCE & TECHNOLOGY? Why do we need EBP? • Extraordinary and unfounded claims of success re Autism are made every day • Science can inform decisions about individual treatment • Maximize selection of effective treatments • Minimize selection of ineffective treatments. • Avoid harmful treatments. • Align treatment options within an individual across disciplines.

  6. WHY SCIENCE & TECHNOLOGY? Why do we need EBP? • Science can also drive systems changes • Set training priorities • Identify levels of support • Help to set policy • Problem: Now everybody is claiming that everything is scientifically-based!

  7. WHY SCIENCE & TECHNOLOGY? Non-Scientific Best Practices? • Basic legal and ethical standards? Necessary but insufficient for EPB • Cultural values? Be careful when these collide with science • Is inclusion values-based or data based? • Can we ever eliminate the need for seclusion and/or restraint

  8. DEFINING EBPWhat are Evidence-Based Practices? 1. An intervention resulting in an outcome that is • Clinically / educationally significant AND • Superior to that obtained otherwise 2. That specifies (a) methods used, (b) treatment target, and (c) who will benefit 3. That is demonstrated via a series of outcome studies that are at least well-controlled and peer-reviewed, if not independently replicated

  9. DEFINING EBP1. Significant outcomes • Must result in a specific and immediate improvement in day-to-day functioning • Improved social, communication, or adaptive skills, or decreased behavior problems • High Impact Outcomes help your child do better TODAY across settings • Be wary of improvements that have “theoretical” but not functional significance

  10. DEFINING EBP 2a. Specific methods • We must know the specific method(s) if we are to replicate the child’s treatment • Proper level of analysis yields predictable, significant & replicable results for a designated target XApproaches: A discipline (ABA), or general theory or model (Developmental)? Far too broad ? Programs: A service delivery model that may specify a method, curriculum, population, resources, and /or setting (EIBI)? Too broad to easily replicate  Methods: A specific technique that may be used for a broad range or narrow range of targets

  11. DEFINING EBP 2b. Specific targets • A close match between the target in the study & the goal for your child makes it more likely you will achieve similar results • Outcomes identified by reviewers can be relatively broad (social skills, communication skills, etc.)

  12. DEFINING EBP 2c. Specific populations • A close match between the children in the study and you child makes it more likely you will achieve similar results • Populations identified by some reviewers are also broad • Children with / without ASD • Children with / without Intellectual Disability • What are the ideal outcomes? • Intervention B is effective in teaching Skill C to Child with characteristics D, E, F and in yielding Outcome G

  13. DEFINING EBP 3. Outcome vs other research • Clinical anecdotes & parent/provider surveys are not considered outcome research • Basic research: Important in testing models but not outcomes • Published reviews of outcome research? Rarely apply a clear standard OR are definitive enough • Exception might be position papers of professional organizations

  14. DEFINING EBP 3. Well-controlled outcome studies • Outcome research? A specific study directly testing the effectiveness of a specific intervention in human subjects • Well-controlled? Meets minimal standards of quality established via peer review • Peer review publication provides an additional level of quality control • But it isn’t it enough because reviewers are not equally rigorous in evaluation of quality

  15. DEFINING EBP 3. Standards for Outcome studies • Recent reviews with overlapping criteria • National Autism Center (2009) • National Professional Development Center for Autism at UNC (2010) • Reichow, Doehring, Cicchetti, & Volkmar, (2010) • All of these • Accept that group designs AND single subject designs are acceptable • Focus on specific methods, and try to identify for which skills these are effective

  16. DEFINING EBP 3. Independent replication • Independent replication: Ultimate test of methodology • Means that others can achieve same results • Protection against fraud • Helps to ensure that some other unidentified factor were not responsible for success

  17. IMPLEMENTING EBPEnsuring Treatment Fidelity • To implement interventions reliably you usually need • Training manual • Training program with fidelity checks and coaching • Places to start • NPDC Evidence briefs: one way to start • Video demonstrations via OCALI’s Autism Internet Modules project • Other trademarked training programs deserve careful attention

  18. IMPLEMENTING EBPMatching Treatment Intensity • How often must the intervention be delivered to begin to see effects? • What kinds of resources do you need to implement intervention faithfully • Specialized staff and staff supervision • Specialized materials and settings • Non-specific treatment variables are rarely considered in evaluating programs • Data suggest that these variable are very important

  19. IMPLEMENTING EBPA culture of data-based decision making • In evaluating individual treatment, do we • Set measurable objectives • Gather data regarding progress towards these objectives • Analyze the data at regular intervals • Make treatment decisions based on – or at least informed by – these results • Are prepared to be wrong! • The best techniques will fail if you do not do all of the above

  20. IMPLEMENTING EBP Costs • What are the costs? • Hiring and training staff • Specialized materials and settings • Opportunity costs: Investing energy and effort here instead of eslewhere • Do the benefits outweigh the costs? • How will this result in a real and significant improvement in their life?

  21. IMPLEMENTING EBPInterventions which lack data? • Don’t judge too quickly! Don’t dismiss all interventions that lack data! • Remarkably few interventions are research-based • All are well-intentioned, so build bridges! • Be open to all possible lessons & future directions • Too new to be tested? It is realistic to expect published, peer-reviewed data within 2-3 years of initial claims • But choosing such an intervention, over a cost-effective evidenced-based practice may not be defensible

  22. IMPLEMENTING EBP Questions parents should ask • If someone makes a claim that a practice is evidence based? • 1. Show me the data (peer reviewed outcome research)! • One really good study or several OK studies from different researchers might make the practice promising • 2. Are the study(ies) good / high quality? • 3. Are these specific methods, not broad programs?

  23. IMPLEMENTING EBP Questions parents should ask • 4. Is the treatment target a priority? • 5. Does the study population and targets match my child and my goals? • 5. Can we achieve the same treatment fidelity and intensity? • Implement, carefully evaluate costs and outcomes, and change course based on the data

  24. IMPLEMENTING EBP Questions practitioners should ask • When setting overall training priorities, practitioners and leaders should focus on • 1) Behavior or skill deficits that A) Occur most often B) Have the greatest impact

  25. IMPLEMENTING EBP Questions practitioners should ask • 2) Cost-effective interventions that A) Have a rapid impact B) Can be implemented reliably C) Are less intensive D) Are clearly effective relative to other interventions • Few interventions will fit all of these criteria • All must be framed within client values & preferences

  26. IMPLEMENTING EBP Questions practitioners should ask

  32. IDENTIFYING EBPTeaching basic social skills

  33. IDENTIFYING EBPUsing EBP to drive treatment • Unless you can quickly show that another technique yields better results, you should always turn to EBP first • EBP: Prioritize ABA-based, positive & proactive interventions informed by functional assessment for reducing challenging behavior before • Relying solely on Medication • Using sensory integration • Using Alternative/complementary interventions (e.g., GFCF diets)

  34. THE FUTURE OF EBPNew approaches • Identify more specific, individualized goals from an EBP using patterns of evidence • Consistent evidence that PECS can be mastered relatively quickly, and that improvements are correlated with complexity of speech and other social-communicative behavior • Choosing methods based on child characteristics • To increase Joint Attention, use RPMT when JA is already established, and PECS when it is not

  35. THE FUTURE OF EBPEvidence-Based Policy • Policy Program Development • Needs Assessment

  36. THE FUTURE OF EBPA new focus on technology • Policy Program Development • Needs Assessment • New Program

  37. THE FUTURE OF EBPIdentifying new services • Policy Program Development • Needs Assessment • New Program
