Examining Predictors of Different ABA Treatments: A Systematic Review.
A child’s unique mix of skills predicts ABA success better than any single high score.
01Research in Context
What this study did
The team read every paper that asked: which child traits forecast ABA success? They kept 45 studies with the kids . Each study measured traits before treatment and tracked learning, language, or behavior gains after at least three months of ABA.
They grouped traits into five buckets: IQ, language, adaptive skills, autism severity, and behavior problems. Then they looked for clear winners—traits that always predicted better outcomes.
What they found
No single trait guaranteed success. A child with high IQ could still make small gains if behavior problems were big. A child with few behavior problems could still struggle if language was very low.
The best predictor was a mix: the right balance of skills for that child’s goals. For example, kids with strong imitation but low language gained more in verbal programs. Kids with high compliance but low play gained more in social-skills programs.
How this fits with other research
Adams et al. (2021) showed the same pattern in movement classes. Preschoolers with higher adaptive scores and fewer tantrums learned motor skills faster. The new review widens the lens—balance matters across all ABA goals, not just gym skills.
Warnes et al. (2005) looked like a contradiction. They found that early onset pattern or regression history did NOT predict later IQ or autism severity. The key difference: they used parent recall of baby milestones, not live baseline tests. Memory-based history is weaker than measured current skills, so both papers can be true.
Raab et al. (2018) gives a practical tool. They showed starting with a child’s existing strengths—assets—speeds learning more than drilling missing skills. The review echoes this: build on the profile you measure today, not the one you wish you had.
Why it matters
Stop using one-score rules like “must have 50+ IQ for intensive ABA.” Instead, run brief probes for the skills your program needs—imitation, compliance, joint attention—and match the lesson plan to the mix you see. You will place kids faster and waste fewer hours on poor-fit goals.

03Original abstract
In the recent literature, there is a broad consensus on the effectiveness of Applied Behavior Analysis interventions for autism spectrum disorder (ASD). Despite their proven efficacy, research in clinical settings shows that these treatments are not equally effective for all children and the issue of which intervention should be chosen for an individual remains a common dilemma. The current work systematically reviewed studies on predictors and moderators of response to different types of evidence-based treatment for children with ASD. Specifically, our goal was to critically review the relationships between pre-treatment child characteristics and specific treatment outcomes, covering different aspects of functioning (i.e., social, communicative, adaptive, cognitive, motor, global functioning, play, and symptom severity). Our results questioned the binomial “better functioning-better outcome”, emphasizing the complex interplay between pre-treatment child characteristics and treatment outcomes. However, some pre-treatment variables seem to act as prerequisites for a specific treatment, and the issue of “what works for whom and why” remains challenging. Future research should focus on the definition of evidence-based decision-making models that capture those individual factors through which a specific intervention will exert its effects.
