Abstract:

Naturalistic Developmental Behavioral Interventions (NDBI) are a class of early intervention methods for autism spectrum disorder (ASD) that combine the principles of applied behavior analysis and developmental psychology, emphasizing naturalistic teaching. In recent years, NDBI have gained international attention, with a continuously expanding empirical research base. This systematic analysis examines the application and effectiveness of six representative NDBI methods in early intervention for ASD. The findings highlight the outstanding advantages of NDBI in promoting the development of social, language, cognitive, and other domains in children with ASD, reducing family costs, and fostering children's initiative. Additionally, the study discusses the application prospects and existing problems of NDBI in China and proposes future research directions. These include clarifying predictive factors and moderating variables that affect intervention effects, exploring effective parent training methods, investigating the combination of different intervention methods and tools, and promoting the localization research and practice of NDBI within China's cultural context. This comprehensive analysis provides valuable reference and inspiration for early intervention in ASD.

The six representative NDBI methods introduced in the study are: Joint Attention, Symbolic Play, Engagement and Regulation (JASPER), Enhanced Milieu Teaching (EMT), Social Communication, Emotional Regulation, and Transactional Support (SCERTS), Pivotal Response Training (PRT), Early Start Denver Model (ESDM), and Parent-Implemented Social Coaching (PIT). These methods share core elements and characteristics of NDBI but have different focuses on target domains and effectiveness.

JASPER primarily targets the core deficits of children with autism in the nonverbal communication domain, enhancing their abilities in joint attention, symbolic play, and shared engagement while also promoting language development. EMT focuses on the language domain, effectively improving the language and verbal communication abilities of children with autism while fostering overall social communication development. SCERTS addresses the core deficits of children with autism in social communication and emotional regulation, building a cross-environmental support system that enhances their social interaction, particularly active participation in social engagement. PRT, as a comprehensive intervention method, targets four “pivotal areas” with a particular emphasis on the role of motivation in the overall development of children with autism, demonstrating favorable outcomes in social interaction and language communication domains. ESDM provides a comprehensive and systematic teaching system to promote the overall development and improvement of core symptoms in children with autism, particularly showing significant effects in cognition, language, and social participation. PIT involves parent training in teaching strategies, enabling parents to implement interventions to improve the social communication abilities of their children with autism while also facilitating the creation of a supportive family environment conducive to their development.

This study presents a comprehensive overview of six representative Naturalistic Developmental Behavioral Interventions (NDBI) methods, examining their concepts, characteristics, applications, and effectiveness. It summarizes empirical evidence supporting the effectiveness of these NDBI methods in improving various developmental domains of children with Autism Spectrum Disorder (ASD), including social interaction, joint attention, play skills, language communication, cognition, adaptive behavior, and executive function. By integrating findings from multiple studies, the study compares the advantages and disadvantages of different NDBI methods.

Furthermore, it discusses the prospects and challenges of implementing NDBI in China from a cultural perspective. The study emphasizes the broad application prospects of NDBI in China while acknowledging the challenges and difficulties hindering its implementation, such as the lack of qualified professionals, training resources, and localized research. To address these issues, the study proposes future research directions, including clarifying predictive factors and moderating variables that influence intervention effects, exploring effective parent training methods, and investigating interventions that combine different approaches or incorporate cutting-edge technologies. Additionally, the study provides insightful pathways for promoting the localization research and practice of NDBI in the cultural context of China.
