Intervention fidelity in Qigong randomized controlled trials: A method review.

Intervention fidelity has important implications for the reliability and validity of a study. Despite the widely reported health benefits of Qigong exercise interventions, the quality of intervention fidelity is less clear. The purpose of this paper is to use a valid intervention fidelity assessment tool to evaluate how intervention fidelity has been addressed in five areas-design, training, delivery, receipt, and enactment-in Qigong randomized controlled studies.
