The Mission of the ABA and PT Podcast is to record and document the work and journeys of major contributors to ABA and Precision Teaching, and thereby stand for incorporating standard measurement and the use of the standard celeration chart into our work and lives. Our pledge is to honour those who have dedicated their life to this field such that my daughter and those that need it, benefit from science and all our field has discovered, that is at risk of getting lost. And the bottom line is that we all need it.

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.

GLOSSARY
Single 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.

20:36 "In single case, you control that by only changing one thing at a time and changing it in specific patterns to eliminate or minimize randomness or confound."
20:47 "In a group design, you do the same kind of control but the way you control is you take averages of the measurement across each group, and then you compare those and you use statistical analysis."
22:20 "We are an inductive approach so that's sort of bottom-up. 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?"
