IntroductionDancers are expected to navigate major challenges in their careers that might take a toll on their physical and mental health. To address underlying factors that might increase dancers’ mental and physical health difficulties, research suggests the systematic use of techniques to build mental skills that can reduce risk factors and enhance protective factors against the challenges dancers encounter. However, existing mental skills training interventions in dance present a lack of consistency in design, content and duration, making it difficult to provide evidence-based recommendations. Hence, dance researchers and practitioners would benefit from a mixed methods systematic review (MMSR) of the why, what and how of these interventions. Adopting tools such as the Template for Intervention Description and Replication (TIDieR) can aid this endeavour by describing replicable aspects of interventions, thus offering dance researchers suggestions on how to understand, appraise and report intervention characteristics and processes in dance. Therefore, this protocol outlines a MMSR that will employ TIDieR to identify and assess characteristics of mental skills interventions in dance.Methods and analysisA systematic search will be undertaken in Psycinfo, Medline, Embase, Sportdiscus, Web of Science and the first 30 pages of GoogleScholar. Following the search, two reviewers will independently screen identified studies in Covidence. One reviewer will extract data using the TIDieR framework and the Mixed Methods Appraisal Tool (MMAT) for quality appraisal, while a second reviewer will check a sample of extracted studies for accuracy. A convergent integrated synthesis will be conducted where quantitative and qualitative evidence will be integrated by qualitising the quantitative data into textual descriptions.Ethics and disseminationThere is no requirement for ethical approval for this systematic review as no empirical data will be collected. The findings will be disseminated through a peer-reviewed publication in a scientific journal and presentations in several different forums (eg, a dance psychology network, at scientific and applied conferences).Prospero registration numberCRD42024537249.
