Self-instructional training manuals and video modeling have been demonstrated to be effective for teaching university students and direct-care staff to conduct behavioral procedures, such as preference assessments and discrete-trials teaching with persons with intellectual disabilities (ID) and children with autism spectrum disorders (ASD). The Assessment of Basic Learning Abilities – Revised (ABLA-R) is an assessment tool used by Applied Behavior Analysis (ABA) service providers for determining the learning ability of clients with ID and children with ASD. In this study, I combined an ABLA-R self-instructional manual (DeWiele et al., 2014) with video modeling and evaluated the effectiveness of the training package for teaching ABA service providers to administer the ABLA-R to a child with ASD. I evaluated the training package using a single-subject, modified concurrent multiple baseline (MB) design across a pair of participants, replicated across three other pairs of participants, plus a modified nonconcurrent MB design across a pair of participants, replicated across one other pair. Participants demonstrated a significant increase in the accuracy with which they administered the ABLA-R to an experimenter from baseline to post-test, and conducted the ABLA-R with high accuracy in a generalization assessment with a child with ASD. An implication of this research is that the self- instructional training package is an effective tool for training ABA service providers to accurately administer the ABLA-R to children with ASD. / October 2016
