The selected research articles were analyzed according to variables of disability type, age, intervention setting, and category of challenging behaviors and intervention strategies. The effect size of the intervention in 17 single subject design studies was analyzed by percentage of non-overlapping data point value. To summarize, developmental delays and autism spectrum disorder were the most common type of disabilities that have been studied. Inclusive kindergarten was the most common environmental research setting being investigated. The effect size of the intervention in research turned out to be highly effective level between 90 to 100% in problematic and adaptive behaviors. Therefore, future research direction were suggested for individualized positive behavior support for preschoolers with developmental delay and at-risk.
