Objectives: Health-related Quality of Life (HRQoL) instruments for cardiovascular disease (CVD) have been commonly used to measure important patient-reported outcomes in clinical trials and practices. This study aimed at systematically identifying and evaluating the psychometric properties of CVD-specific HRQoL instruments.
Methods: We searched CINAHL, Embase, and PubMed from inception to January 20, 2022. Studies that reported psychometric properties of CVD-specific instruments were included. Two reviewers independently assessed the methodological quality using the Consensus-based Standards for the Selection of Health Measurement Instruments methods on evaluating measurement properties and quality of evidence. Seven psychometric properties, including structural validity, internal consistency, test-retest reliability, convergent validity, divergent validity, discriminative validity, and responsiveness, were evaluated.
Results: We identified 142 studies reporting psychometric properties of 40 instruments. 5 (12.5%) instruments demonstrated measurement properties with "sufficient" or "inconsistent" ratings. 16 (40.0%) instruments did not report any responsiveness evidence. Of the 40 instruments, 15 (37.5%) instruments were rated "sufficient" with high quality of evidence on internal consistency, 4 (10.0%) on structural validity, convergent validity and divergent validity and 3 (7.5%) on discriminative validity.
Conclusions: When measuring patient-reported outcomes in clinical trials or routine practice, it is important to choose instruments with established psychometric properties.
