title: Temporary practice pause then resumption (TPPR) study design: an extension of the withdrawal study design to complementary and alternative medicine mind and body interventions (CAM-MABI).
abstract: Study of complementary and alternative medicine's mind and body interventions (CAM-MABI) is hindered not only by the inability to mask participants and their teachers to the study intervention but also by the major practical hurdles of long-term study of practices that can be lifelong. Two other important methodological problems are that study of newly trained practitioners cannot directly address long-term practice, and that long-term practitioners likely self-select in ways that make finding appropriate controls (or a comparison group) challenging. The temporary practice pause then resumption study design (TPPR) introduced here is a new tool that extends the withdrawal study design, established in the field of drug evaluation, to the field of CAM-MABI. With the exception of the inability to mask, TPPR can address the other methodological problems noted above. Of great interest to investigators will likely be measures in practitioners of CAM-MABI that change with temporary pausing of CAM-MABI practice, followed by return of the measures to pre-pause levels with resumption of practice; this would suggest a link of the practice to measured changes. Such findings using this tool may enhance our insight into fundamental biological processes, leading to beneficial practical applications.
