Abstract In this pre-test, post-test study, principles of applied behavior analysis (ABA) were taught to a group of dietetic interns using an online module. Results indicate positive improvements in use of objective, behavioral terminology to describe relevant behavior, environmental events, and possible functions of behavior in clinical case studies for fifteen out of eighteen participants. The availability of technology for virtual training in assessment of the functions of behavior presents unique opportunities to provide training in functions of behavior to students in human services outside of ABA to aid them in future career settings.
