Ins and Outs of Applied Behavior Analysis (ABA) Intervention in Promoting Social Communicative Abilities and Theory...

Social-communicative abilities and theory of mind (ToM) are crucial for successful social interactions. The developmental trajectories of social and communicative skills characterizing individuals with Autism Spectrum Disorder (ASD) are rather complex and multidimensional, including components related to theory of mind. Due to its mentalistic nature, theory of mind has been rarely addressed as an outcome for Applied Behavior Analysis (ABA) intervention in children and adolescents with ASD. However, there is evidence that ABA intervention might be effective in promoting social abilities in individuals with ASD. Thus, this topic is worth investigating. We present a systematic review to explore the Ins and Outs of an ABA approach to promote social and communicative abilities and ToM in children and adolescents with ASD. We applied a PRISMA checklist to consider studies published up to December 2024. The keywords that we used were ToM, perspective-taking, false belief, social cognition, and mental states, in combination with ABA intervention and ASD (up to age 18). We searched for studies using Scopus, Google Scholar, and Medline. We included twenty studies on perspective-taking, identifying emotions, helping, detecting eye gazing, and social engagement, reviewing fifteen dedicated to teaching the interpretation of mental states (involving 49 children and 10 adolescents). The ToM was addressed with a multiple baseline design on target behaviors associated with ToM components such as identifying emotion, helping behaviors, and mental states. The intervention included a behavioral package consisting of Behavioral Skill Training, Derived Relations, video modeling, and role playing. The results indicated a significant number of participants who followed ABA intervention to promote social abilities and mastered the target behavior in ToM tasks; however, they showed maintenance and generalization issues across trials and settings. The role of predictors was highlighted. However, the studies are still rare and exhibit specific methodological limitations, as well as some clinical and ethical considerations. More research is needed to define best practices in ABA intervention to promote social abilities in individuals with ASD.
