Evidence¶

Lovaas Model of Applied Behavior Analysis 2010¶

q3 · i0 · review · r2

WWC review of the one functional ability outcome in Sallows and Graupner (2005). The improvement index for functional abilities is +4 percentile points from one finding in one study; the effect was not statistically significant and not substantively important.

"Sallows and Graupner (2005) examined one functional ability outcome. The authors found, and the WWC confirmed, that the effect was not statistically significant nor was the effect size large enough to be considered substantively important according to WWC criteria."
