The effectiveness of TEACCH-based interventions in improving adaptive skills in children with autism spectrum disorders: a systematic review and meta-analysis

This study demonstrates that TEACCH-based interventions can significantly enhance a range of developmental skills in children with ASD. By comparing intervention settings, durations, and levels of parental involvement, and identifying the specific conditions under which TEACCH yields the greatest benefits-namely, structured clinical environments, medium-term implementation periods, and intentional parent participation. These findings provide actionable evidence on how to optimize TEACCH-based programs in practice and emphasize the importance of context-specific adaptation and high-fidelity delivery when applying these interventions across diverse populations and service settings.
