Development, piloting and validation of the Recommending Cardiac Rehabilitation (ReCaRe) instrument
Research output: Contribution to journal › Article
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; 0.271.0), 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 (a = 0.93, k = 0.37); perceived service accessibility (a = 0.91,
k = 0.67); perceived benefit (a = 0.97, k = 0.47); perceived barriers and attitudes (a = 0.82, k = 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
