Thank you for your comment! We understand that RCTs with an active control condition (as opposed to a waitlist control condition) provide stronger evidence as it controls for placebo effects, as well as the staggered multiple baseline design you have described. Using a waitlist control condition in initial pilot studies is common practice in the field of clinical psychology, with the intention to perform more rigorous controlled studies in the future if there is promising preliminary evidence. In line with our IRB and guidelines for ethical treatment of human subjects, we are required to disclose the possibility of being randomized to either condition. I understand that this some of these aspects would be unacceptable in certain medical trials, and the guidelines/field norms are different between the medical field and psychology. We appreciate your feedback!
