Abstract

Background
Health practitioners’ values, attitudes and beliefs largely determine their referrals to cardiac rehabilitation (CR).

Objective
To develop and test the Recommending Cardiac Rehabilitation scale (ReCaRe), designed to assess health professionals attitudes, values and beliefs to CR referral.

Methods
ReCaRe was appraised for: content validity (Delphi method, expert panel); interpretability and face validity (interview, health professionals); factor structure and internal consistency (survey, health professionals); and test-retest reliability (survey, health professionals). Normative scores were collated.

Results
ReCaRe initially comprised 75 items. Initially, a Content Validity Index (CVI) was calculated for ratings of item relevance (CVI range; 0.27–1.0), which resulted in the removal of 19 items. After preliminary validation and psychometric testing, 34 items were factor-analysed (n = 24) providing a 17-item, four-factor scale: perceived severity and susceptibility (α = 0.93, κ = 0.37); perceived service accessibility (α = 0.91, κ = 0.67); perceived benefit (α = 0.97, κ = 0.47); perceived barriers and attitudes (α = 0.82, κ = 0.49). ReCaRe normative scores (n = 75) are reported.

Conclusions
This psychometric analysis found ReCaRe to demonstrate good face validity, internal consistency and fair to substantial test-retest reliability. The next step is to validate these initial findings on a larger sample size to confirm whether ReCaRe can enable identification of factors impacting CR referral.
