Music-based interventions are used to address a variety of problems experienced by individuals across the developmental lifespan (infants to elderly adults). In order to improve the transparency and specificity of reporting music-based interventions, a set of specific reporting guidelines is recommended. Recommendations pertain to seven different components of music-based interventions, including theory, content, delivery schedule, interventionist, treatment fidelity, setting, and unit of delivery. Recommendations are intended to support Consolidated Standards for Reporting Trials (CONSORT) and Transparent Reporting of Evaluations with Non-randomized Designs (TREND) statements for transparent reporting of interventions while taking into account the variety, complexity, and uniqueness of music-based interventions.
