Differential Reinforcement of Low Frequency Behavior as an Interdependent Group Contingency for Children Diagnosed with Autism Spectrum Disorder.

An ABAB reversal design was employed to evaluate the effect of differential reinforcement of low (DRL) frequency behavior as an interdependent group contingency on the frequency of vocal disruptions of five males, 6-14-years old, diagnosed with an autism spectrum disorder. The results showed lower frequencies of vocal disruptions during intervention conditions as compared to baseline conditions; the combination of DRL and interdependent group contingency was effective at reducing the target behavior from baseline levels. Implications of concurrent interventions for the applied setting are discussed.

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.
