Evidence-based practice in ABA is a complex decision-making process involving frequent adjustments in goals and procedures as informed by science, client need, and clinical wisdom. Consistent with the science's foundations, incredible gains are possible for children with autism when practitioners are systematically trained to understand, produce, and be responsive to shifting conditions for change. However, minimal standards for training promote inflexibility and rule following, at the expense of frequent and responsive adjustments. Although research has demonstrated that well-trained staff can effectively implement flexible procedures using in-the-moment assessment and clinical judgment, minimal research has targeted and evaluated the development of these repertoires. Therefore, the purpose of this study was to evaluate the effects of a staff training package, including an in-service training and in vivo training sessions, on staffs' ability to make responsive, goal-directed, and rationale-based decisions directed towards accelerating progress with vocal manding for children with autism. The evaluation was the second part of the larger Change AGENT Project. Results suggested the training was effective at producing socially validated progress across staff and child measures. In essence, the trainer, staff, and child acted as change agents for one another's behavior within the flexible paradigm. Implications, limitations, and future directions are …

When autism interventionists within behavioral intervention programs continually assess the child's behavior and context and adjust their teaching behaviors accordingly, the child can quickly progress towards their goals. While evaluations of flexible behavior-change techniques implemented by experienced clinicians are present in the literature, systematic evaluations of staff training procedures to train interventionists in responsive decision making are lacking. In the current study, flexible training procedures were utilized to not only teach direct-line staff to make decisions based on the learner's behavior, but also to understand and articulate the variables they were responding to. During in vivo training sessions, trainers tailored their use of instructions, modeling, practice, feedback, narration modeling and shaping, and decision-making guidance to the dynamic needs of the staff and child. The effects of the treatment package, which consisted of an in-service training and in vivo training sessions, were measured by observing staff teach vocal manding, which was chosen based on the importance of the skill for the child and because it afforded many opportunities for the staff to learn to make decisions about how to occasion and shape responses. The three children with autism who participated in the study made progress in terms of increasing their frequency …
