A Cultural Generalization: An Effective Training for Staff Integrity on DTT in the Application of the PEAK in Brazil

Promoting the Emergence of Advanced Knowledge (PEAK) direct training is an evidence-based curriculum with extensive research. Treatment integrity is one of the critical components of an effective treatment. In developing countries where training opportunities are scarce, providing precise training poses a challenge. The current study evaluated the effectiveness of behavioral skills training (BST) role-play to train three staff members to implement the PEAK-DT language curriculum, using discrete trial teaching (DTT) with three learners with autism spectrum disorder (ASD). Not only did the staff members implement the programs with high treatment integrity, but the learners also improved their performance on targeted skills. In addition, this study considered maintenance and generalization of the skills learned. Overall, data show that the BST role-play was successful as the staff members enhanced the skills of three learners with autism.
