Dance-Based Interventions for Mental Health: A Comprehensive and Quality-Sensitive Umbrella Review of Definitions, Measurement Practices, and Evidence Fragmentation.
Abstract
Dance-based interventions are increasingly used to support mental health and well-being across clinical, community, and educational contexts. However, the review-level evidence remains conceptually and methodologically fragmented. This quality-sensitive umbrella review synthesized 90 review articles identified across five databases. Systematic reviews and meta-analyses were appraised using AMSTAR 2, while scoping, narrative, literature, and clinical reviews were assessed using adapted review-appraisal criteria. Findings from systematic reviews and meta-analyses were used primarily to interpret effectiveness evidence, whereas nonsystematic reviews were used to map conceptual definitions, practice traditions, and measurement issues. The synthesis showed that the field is fragmented at three interrelated levels. First, intervention labels and delivery models are inconsistent, ranging from clearly defined dance/movement therapy to broad and underspecified uses of dance. Second, effectiveness is conceptualized differently across intervention traditions, with therapy-oriented reviews emphasizing symptom reduction and non-therapy-oriented reviews foregrounding well-being, vitality, social connection, and embodied experience. Third, outcome assessment relies predominantly on generic psychological scales, with limited use of movement-sensitive or dance-specific measures. Quality-sensitive evidence suggests that dance-based interventions show promise for well-being, social connection, emotional regulation, and selected symptom outcomes, but confidence remains limited by low review quality, heterogeneous populations, inconsistent intervention reporting, and insufficient attention to primary-study overlap. Future research should move beyond asking whether dance works in general and instead specify what kind of dance, for whom, through which mechanisms, and according to which model of mental health and well-being.
Clinical relevance
Across existing review-level evidence, are dance-based interventions for mental health and well-being conceptually well-defined, methodologically consistent, and sufficiently synthesized to support evidence-based clinical recommendations? __SNAPSHOT__ {"studyDesign":"Quality-sensitive umbrella review (synthesis of systematic reviews, meta-analyses, scoping reviews, narrative reviews, literature reviews, and clinical reviews)","setting":"Multi-database synthesis across five databases; clinical, community, and educational contexts represented across included reviews; specific databases not reported in abstract","sampleSize":"90 review articles included; number of primary studies and participants across included reviews not reported in abstract","population":"Individuals receiving or studied in the context of dance-based interventions for mental health and well-being; settings span clinical, community, and educational contexts; age range and diagnostic characteristics of underlying populations not specified in abstract","intervention":"Dance-based interventions broadly defined, encompassing formal dance/movement therapy (DMT) delivered by credentialed therapists through to non-therapy-oriented dance programs (e.g., recreational, educational, community dance)","comparator":"Not applicable (this is a methodological and conceptual synthesis of review-level literature, not a head-to-head effectiveness trial)","primaryOutcome":"Synthesis of (1) conceptual definitions and delivery models of dance-based interventions; (2) measurement practices for mental health outcomes; and (3) patterns of evidence fragmentation across the review literature","followUp":"Not applicable (umbrella review; follow-up duration of underlying primary studies not reported in abstract)","fundingSource":"Not reported"}
Key findings
The umbrella review synthesized 90 review articles and identified fragmentation operating at three interrelated levels. First, intervention labeling and delivery models are inconsistent across the literature, ranging from clearly operationalized dance/movement therapy (DMT) to broad and underspecified uses of the term 'dance.' Second, the conceptualization of effectiveness differs systematically between intervention traditions: therapy-oriented reviews emphasize symptom reduction (e.g., depression, anxiety scales), whereas non-therapy-oriented reviews foreground constructs such as well-being, vitality, and social connectedness. Third, measurement practices are heterogeneous in ways that compound the definitional inconsistency. No pooled effect sizes, confidence intervals, p-values, or NNT/NNH values are reported in the abstract; quantitative synthesis of effectiveness was drawn primarily from the systematic reviews and meta-analyses within the corpus, while nonsystematic reviews were used to map conceptual and measurement issues. AMSTAR 2 was applied to systematic reviews and meta-analyses; adapted appraisal criteria were applied to nonsystematic review types. The methodological quality of included reviews is not quantitatively summarized in the abstract.
Practice implications
This umbrella review establishes that the review-level evidence base for dance-based mental health interventions is structurally fragmented at the levels of terminology, effectiveness conceptualization, and outcome measurement — findings that directly limit the validity of any pooled effect estimates derived from this literature. The study does not establish that dance-based interventions are effective or ineffective for any specific mental health diagnosis; that determination requires primary-study-level evidence of sufficient methodological quality. The findings apply to the review literature as a whole and do not permit subgroup conclusions about specific populations (e.g., adults with major depressive disorder, children with anxiety, older adults with dementia), specific intervention formats, or specific delivery intensities. Patients likely underrepresented include those from low- and middle-income countries, racial and ethnic minority groups, older adults with severe psychiatric illness, and pediatric populations — though this is an inference from the broader literature, as the abstract does not explicitly enumerate representational gaps. The clinical implication is that a clinician seeking to justify or implement a dance-based intervention for a specific mental health indication cannot yet rely on a coherent, high-quality evidence synthesis. Practice should not change on the basis of this review alone; rather, this review serves as a methodological call for field-wide standardization of definitions, intervention operationalization, and outcome measurement before robust effectiveness conclusions can be drawn.

Clinicians cannot currently derive diagnosis-specific or population-specific practice recommendations from this literature. The primary value of this work is methodological: it articulates the standardization prerequisites (consistent intervention definitions, shared effectiveness constructs, harmonized outcome measures) that must be met before high-confidence clinical guidance can emerge.
