Although it is widely accepted that procedural fidelity data are important for making valid decisions about intervention effectiveness, there is little empirical guidance for researchers and practitioners regarding how to assess procedural fidelity. A first step in moving procedural fidelity assessment research forward is to develop a…

The acquisition of new skills may be hindered when teaching procedures vary from previously validated approaches or contain errors. In the present study, we compared the acquisition and maintenance of response chains taught using a perfectly implemented system of least prompts and a multiple verbal prompts procedure (i.e., addition of multiple…

Delivering high-probability (high-p) request sequences is an effective method to increase compliance across settings. To date, researchers have used frequency of compliance and latency to initiate low-probability (low-p) requests to document these effects. Both measures focus on events just prior to and during the low-p task. In these two studies…
