The Victorian Institute of Sport Assessment – Achilles is fundamentally flawed and unfit for clinical practice or research: A Rasch Measurement Theory Analysis using COSMIN recommendations
The VISA-A has inadequate structural validity, borderline internal consistency and poor measurement invariance. Thus, the VISA-A does not meet with COSMIN criteria for construct validity due to issues with structural validity and measurement invariance. Thus, the VISA-A cannot be recommended for use, and should not be used in clinical practice or research. However, if the VISA-A has been used, analysis using only items 1-6, with responses collapsed into a 4-point scale provides the best structural validity.
