Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i0 Neither of two communication/language outcomes was statistically significant, and neither effect size was substantively important; the average improvement index is –3 percentile points (range –4 to –3). → Lovaas Model of Applied Behavior Analysis 2010
Evidence¶
Lovaas Model of Applied Behavior Analysis 2010¶
Lovaas Model of Applied Behavior Analysis. (2010). WWC Intervention Report, U.S. Department of Education, What Works Clearinghouse. https://ies.ed.gov/ncee/wwc/InterventionReport/295
q3 · i0 · review · r3
WWC review of the Sallows and Graupner (2005) randomized controlled trial (23 children randomly assigned to therapist-led or parent-directed Lovaas treatment). "neither effect was statistically significant" and neither effect size met the substantively-important threshold; average improvement index –3 percentile points, range –4 to –3.
"Sallows and Graupner (2005) examined two outcomes. The authors found, and the WWC confirmed, that neither effect was statistically significant. Neither effect size was large enough to be considered substantively important according to WWC criteria."
