A single-case multiple baseline design across three families was used to evaluate the impact of a manualized Prevent-Teach-Reinforce for Families (PTR-F) process for addressing challenging behavior (CB) when delivered in a remote format (PTR-F: R). Results across three U.S. families showed that (a) a functional relation existed between parent implementation of the strategies and reductions in child's CB, (b) families achieved high levels of implementation fidelity for behavior intervention plans developed using the PTR-F: R process, and (c) families rated the PTR-F: R process and the intervention plans positively. The results replicated findings from previous research on the general efficacy of the PTR process while adapting the method for use in a remote format. Implications for practice and future research are discussed.
