#7: The What and How of Evidence Practice
Evidence-based practice can be a touchy subject for ABAs and OTs alike. Dr. Josh Pritchard of the Lodestone Academy shares his insights on collaboration and the strengths and weaknesses of single-case design versus group-case design.Dr. Pritchard discusses the groundbreaking study that put standards in place for sensory integrations for children with ASD. He further provides ways that ABAs and OTs can improve their collaboration by using measurements to determine the effectiveness of their interventions.HIGHLIGHTS01:50 Introducing Dr. Josh Pritchard08:54 Research and OT strategies: Challenges to collaboration 17:19 Evidence-based practice: Single case design vs group design29:57 The Bedtime Pass33:51 Discussing the study "Effectiveness of Sensory Integration Interventions in Children With Autism Spectrum Disorders"38:49 Insights for OTs and measuring the effectiveness of their interventionsGLOSSARYSingle case design - Takes a single unit, many times a single person, or a setting or small group of people but treated as a unit, and use that unit as its own control, and involves repeated measures, and manipulation of a single, independent variable in specific patterns.Group case design - Uses the same kind of control but using averages of the measurement across each group and compares using statistical analysis. The goal is to find statistical significance.

We want to gather lots of data and look at it and discover patterns versus a hypothetical deductive approach, which is sort of top-down, come up with a theory and then try to just prove it. And if you can't disprove it, then it's good."27:24 "The single-case design is good for the development, refinement, make more efficient a technology and then you can extrapolate that. I think this'll work for many. The group-design actually is good for telling the effectiveness and does it, in fact, work for most people."43:17 "The challenge to the behavior analyst and the value of the OT, there's some stuff we want to change in life that's got the je ne sais quoi of, I can't say what that is but I can say when it's happening or not. And we got to dive in and what is that?"
