In a recent study, CARD Researchers Dr. Michele Bishop and Dr. Amy Kenzer found group classroom training to be effective in teaching behavioral therapists to administer brief preference assessments to children with autism spectrum disorders (ASD). A major component of applied behavior analysis (ABA) treatment is the delivery of preferred stimuli as reinforcement. Therefore, preference assessments are conducted to identify highly preferred stimuli. Such assessments ought to be conducted frequently since a child’s preferences may change. For this reason, Dr. Michele Bishop and Dr. Amy Kenzer set out to evaluate the effectiveness of classroom training in teaching behavioral therapists to administer brief preference assessments to children with ASD during therapy sessions.
