Validity and test-retest reliability of a patient-reported outcome measure for an outpatient cardiac rehabilitation programme

Abstract

Background/Aims This article details how a patient-reported outcome measure (PROM), termed PROM-CR1, was tested for acceptability, validity and test-retest reliability at the end of an outpatient cardiac rehabilitation programme. Methods PROM-CR1 was completed by 138 service users (mean age 66.95 years, range 42–94 years; 115 males, 23 females; with a range of cardiac diagnoses), who used the tool at home twice: once at the end of the outpatient cardiac rehabilitation programme and 1 week later. Results PROM-CR1 demonstrated good acceptability, construct and concurrent validity, and test-retest reliability. The construct validity analysis highlighted that one item required removal from the PROM-CR1. Conclusions A finalised 30-item version of the tool will now be widely disseminated and further evaluated within cardiac rehabilitation clinical practice.

Development of a core outcome set for cardiac rehabilitation in patients with myocardial infarction: a study protocol

“…For the study, we will focus on ‘what to measure’. The outcome measures, especially those for patient-reported outcomes, 29 should be searched, assessed and agreed on by different stakeholders according to the guideline on ‘how to select outcome measurement instruments for outcomes included in a COS’. 31 Thus, we plan to conduct a new study to recommend ‘how to measure’ core outcomes, after the final COS is developed.…”

“…The outcomes will be presented according to specific interventions and follow-up lengths, because previous research has shown that this approach may improve the adoption of COSs by Chinese trialists. 29 …”
