Reichow, B., Volkmar, F.R., & Chiccetti, D.V. (2008).  Development of the evaluative method for evaluating and determining evidence-based practices in autism.  JADD, 38, 1311-1319. DOI on paper.

 

This information is applicable across the different papers that I might do.  Reference early and often.

 

  • Has any intervention been determined to be an evidence-based practice?
  • older methods of determining EBP were not adequate
  • determined a new method for EBP
  • EBP - first began in medicine and moved to the social sciences
    • most organizations - guidlines endorsing EBP
    • many different names for the same thing
  • no universally accepted method for determining EBP
    • 2 independent randomized control studies usually meets the evidence
    • some use this as the only standard
    • differences - what is the strength of the evidence?
  • NRC - committee - no practice is considered strongly evidence-based - backed up by other studeies
    • many different definitions
    •  some might not have been sensitive enough
    • limitations
      • operational method for evidence
      • narrow scope of what is evicense
      • single subject not treated
        • much of the research on children with disabilities is single subject!
  • development of evaluative method for determining EBP in autism
    • rubrics of rigor
    • guidelines for reporting strength
    • criteria for determining EBP
    • standardized for clinicians researchers and practitioners
      • individual and group ratings
    • allows for a corrective so that different methodologies could be included (EXCEPT QUALITATIVE)
    • first guidelines for mixed methods!
  • rubrics of rigor
    • once created for single subject and another for group designs
      • primary indicators - three ratings
      • secondary indicators - two ratings
    • TABLES ARE AVAILABLE IN THE STUDY ITSELF
    • similar definitions wherever possible
      • participant characteristics
      • dependent measures
      • independent variables
    • secondary
      • IOA
      • blind raters
      • procedural fidelity
      • generalization and maintenance
      • social validity
  • measures of strength
    • strong
    • adequate
    • weak
    • TABLES ARE AVAILABLE IN THE PAPER ITSELF
  • criateria for EBP
    • similar to those used in other social sciences
      • established - multiple sound studies, two independent groups
      • promising - multiple studies, weak rigor or other limitations
        • use these with caution and monitor closely
  • reliability and validity of the rubrics
    • field tested (Reichow et al 2007)
    • 8 group designs and 10 single subject designs
    • 2 independent raters
      • reliability was good to perfect
      • Doehring et al 2007 replication
    • validity
      • concurrent validity - aligned with previous definitions
      • content - operationalization of what is EBP
      • common usage - face validity
  • future studies
    • strengthen validity by training novice raters and compare to experienced raters
    • different types of raters
  • Discussion
    • one of the first criteria for EBP to provide operationalization
      • group designs
      • single subject designs
    • should not base science solely on group design
    • difficulty - how many single subject studies constitute a group design?
      • 8 participants from experiments were equal to a group design
      • needs empirical validation - WONDER HOW YOU WOULD DO THAT?
        • averaged two criteria from two different sets of recommendations
    • translation of research to practice
      • eventually - have practitoners use this rubric to evaluate evidence
      • tried to keep the definitions from using too much jargon - might seem to simple
        • but the criteria are strong
        • might not be enough to close the gap
      • access to information is crucial
        • standardized method for accessing and evaluating research reports
      • guides for locating evidence
        • Locas & Cutspec 2005
        • Petticrew & Roberts 2006
        • McHugo & Drake 2003
          • most guides in the social sciences are not user-friendly
    • different research guides - help with at standardized way of reviewing the evidence
    • could put strength ratings in reviews - a kind of meta-analysis
      • others wouldn't have to re-review?
    • future work - does the review method generalize?
  • Conclusion
    • we don't have EBP for children with autism yet
    • don't lower your standards!
    • Standardize the instrument instead
    • seems to be a valid assessment tool
    • could be applied to both researchers and practitioner use
