Development of communication skills in an adolescent with autism, using alternative communication: a case report

ABSTRACT Alternative communication has been successfully used in interventions to develop communication skills in children with ASD. However, few studies in Brazil have approached nonverbal adolescents with autism. This article aimed to demonstrate the impact of using an alternative communication system on the development of communication skills in a nonverbal adolescent presented with ASD. This is a single-case study with longitudinal intervention. Skills were assessed with the Communication Assessment in Autism Spectrum Disorder (ACOTEA). There was progress in communicative and behavioral skills. Receptive communications had a greater variation between the first, second, and third applications, increasing from 50% to 66.60% and then 83.30%, followed by social behavior, which increased from 45.80% to 70.80% and then 75%. The use of alternative communication with a robust communication system indicated evidence of the development of communication skills and social behavior in the adolescent with ASD that received the treatment.
