Performance Quality Assessment in Ballet, Modern and Contemporary Dance: A Two-Step Systematic Review.

Abstract

Introduction: Measurement of performance quality in dance is important but challenging and few dance performance quality measures exist. This study aims to (1) identify and (2) assess the quality of dance performance outcome measures for ballet, modern and contemporary dance. Methods: A 2-step systematic review with two separate literature searches was conducted. Step 1 involved a systematic review to identify all ballet, modern and contemporary dance performance quality outcome measures. Step 2 involved a systematic review to identify studies that reported measurement properties (eg, validity, reliability) of the tools identified in Step 1. A comprehensive electronic search of MEDLINE, SPORTSDiscus, CINHAL, Embase and IADMS Bibliography was conducted from inception to November 2020 (Part 1) and February 2021 (Part 2). To evaluate the quality of each dance performance outcome measure, three steps were conducted (1) assessment of methodological quality using the COSMIN checklists, (2) evaluation of results against criteria of good measurement properties and (3) summary of the evidence and an overall rating of evidence using a modified Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Results: Fifteen dance performance quality outcome measures were identified (Step 1). Seventeen studies reported measurement property data for 14 of 15 identified outcome measures (Step 2). The majority of the 34 measurement property outcomes were rated as doubtful (COSMIN checklists), and demonstrated sufficient measurement properties. Only one outcome measure, the Radell Evaluation Scale for Dance Technique (RESDT), was assessed as having low and moderate quality evidence for validity and reliability respectively. The remaining 13 tools were rated as having very low-quality evidence (GRADE criteria). Conclusions: Due to low quality, the 15 dance performance quality tools cannot be confidently recommended for use at this time. Dance teachers, clinician and researchers should consider feasibility issues and use the tools with caution until adequate high-quality evidence is available.
