Dosage in Applied Behavior Analysis: Effect on Adaptive Behavior, Goal Attainment, and Dangerous Behavior.
Article in Journal of autism and developmental disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeApplied behavioral analysis is the most common intervention for autistic children. It has long been proposed that more hours per week in ABA produce better outcomes. ABA practice guidelines typically recommend 30-40 h per week for young autistic children. While some studies support a dosage effect, other studies find no predictive relationship between ABA treatment hours and a range of child outcomes. Thus, the dosage question remains open, leaving parents and providers unsure of the ideal dosage of ABA for an autistic child to make meaningful progress. Real world data (RWD) can fill the gap between community treatment and controlled research often conducted by universities.
methodsIn this study, we examined the RWD data from 725 autistic children receiving ABA as part of community-based care. Using longitudinal multilevel modeling, we examined the relationship between average hours of ABA per month and change on proximal and distal measures: adaptive behavior, goal attainment, and dangerous behavior.
resultsDosage was a significant predictor of goal attainment, indicating that clients who spent more time in treatment met more goals. Conversely, the relationship was negative for adaptive behavior and communication, such that higher hours predicted slower progress in these domains. Finally, dangerous behavior decreased over time and was independent of hours. Secondary analyses demonstrated that communication abilities at baseline predicted treatment outcomes above and beyond dosage, except for dangerous behavior.
conclusionWhile more research is needed, this study suggests that practice guidelines should temper language around dosage and ABA.
