This review provided a systematic analysis of mathematics interventions for individuals with autism. Using success estimates, strength-of-evidence ratings, and percentage of nonoverlapping data, the authors identified 13 studies that provided evidence of effective to very effective outcomes using mathematics accuracy measures for at least one intervention. Five studies with measurements related to engagement had 100% success estimates with at least adequate evidence and had percentage of nonoverlapping data scores indicating very effective interventions for the majority of participants across studies. For accuracy-based outcomes, a majority of successful interventions included both behavioral and mathematical components. Although the combination of mathematical and behavioral components appears to be promising, differences in interventions and outcomes and limited details on participant characteristics limit conclusive clinical recommendations.
