Abstract

As a field, Behavior Analysis lacks an evidence based solution to assessing and treating language deficits in individuals with brain injuries. Research suggests that using direct instruction with persons with brain injuries is the most effective approach for teaching skills. Research on the PEAK Relational Training System suggests it may be applicable to adults with brain injuries because it does not have an age maximum and it assesses and trains complex language skills. The purpose of the current research is to determine the PEAK Relational Training System's potential applicability in assessing language and cognition functioning in adults with brain injury. 20 adults with brain injuries served as the participants for this study. Using a Pearson Correlation, the relationship between performance on the PEAK assessment and the Ross Information Processing Assessment (RIPA-2), pre-morbid education levels, Glasgow Coma Scale scores, and the location of injury in the brain was analyzed. Significant relationships between PEAK and RIPA-2 scores and PEAK and number of years since injury were shown. Furthermore, implementation of the PEAK was shown to be highly reliable. The current research has shown the effectiveness of the PEAK Relational Training System Direct Training Assessment for adults with brain injury.
