Abstract
Abstract The shortage of opportunities to access effective interventions for autism in developing countries is a major concern. Research on parent-implemented interventions is critical for the dissemination of evidence-based treatments. The present study evaluated the efficacy of a parent-implemented intervention program that is offered to low and lower middle-class families in northern Brazil. The participants were three children who were diagnosed with autism and their respective parents/caregivers. All of the parents had received training on the implementation of discrete-trial teaching. We collected data on the children's performance and evaluated the integrity of the parent-implemented intervention. The results showed improvements in performance for two of the three children whose parents implemented the intervention with a high degree of integrity. For the third parent whose child had lower performance, low attendance during the training sessions was correlated with the child's slower rate of acquisition. These findings support the potential benefits of parent-implemented intervention programs for children with autism and extend to the socio-cultural context of developing countries, such as Brazil.
