Abstract
This study aims to analyze the development of communication in dizygotic twins with autism following intervention with the DHACA® method (Development of Communication Skills in Autism). It is a longitudinal case study with a qualitative and quantitative approach conducted with a pair of dizygotic twins (GM and GF), aged 3 years and minimally verbal, using the Childhood Autism Rating Scale (CARS) and the ACOTEA protocol (Communication Assessment in Autism Spectrum Disorder) over 3 sessions, and subjected to 20 intervention sessions with the method. The evaluation results demonstrate an increase in scores on the instruments, indicating greater development of expressive, comprehension, and social interaction skills, evidenced in receptive communication in GF and social behavior in GM, with a 33.33% improvement in the ACOTEA. The twins’ vocabulary also increased, with the acquisition of new lexical categories using DHACA®. The use of a robust communication system contributed to the development of communication skills in twins with ASD.
