Psychometric validation of the cardiac rehabilitation barriers scale.

Bottom Line: Maximum likelihood factor analysis with oblique rotation resulted in a four-factor solution: perceived need/healthcare factors (eigenvalue = 6.13, Cronbach's α = .89), logistical factors (eigenvalue = 5.83, Cronbach's α = .88), work/time conflicts (eigenvalue = 3.78, Cronbach's α = .71), and comorbidities/functional status (eigenvalue = 4.85, Cronbach's α = .83).Test-retest reliability of the CRBS was acceptable (intraclass correlation coefficient = .64).The CRBS consists of four subscales and has sound psychometric properties.

ABSTRACT

Objective: The purpose of this study was to investigate the factor structure and psychometric properties of the Cardiac Rehabilitation Barriers Scale (CRBS).

Design, setting, and participants: In total, 2636 cardiac inpatients from 11 hospitals completed a survey. One year later, participants completed a follow-up survey, which included the CRBS. A subsample of patients also completed a third survey which included the CRBS, the Cardiac Rehabilitation Enrolment Obstacles scale, and the Beliefs About Cardiac Rehabilitation scale three weeks later. The CRBS asked participants to rate 21 cardiac rehabilitation barriers on a five-point Likert scale regardless of cardiac rehabilitation referral or enrolment.

Results: Maximum likelihood factor analysis with oblique rotation resulted in a four-factor solution: perceived need/healthcare factors (eigenvalue = 6.13, Cronbach's α = .89), logistical factors (eigenvalue = 5.83, Cronbach's α = .88), work/time conflicts (eigenvalue = 3.78, Cronbach's α = .71), and comorbidities/functional status (eigenvalue = 4.85, Cronbach's α = .83). Mean total perceived barriers were significantly greater among non-enrollees than cardiac rehabilitation enrollees (P < .001). Convergent validity with the Beliefs About Cardiac Rehabilitation and Cardiac Rehabilitation Enrolment Obstacles scales was also demonstrated. Test-retest reliability of the CRBS was acceptable (intraclass correlation coefficient = .64).

Conclusion: The CRBS consists of four subscales and has sound psychometric properties. The extent to which identified barriers can be addressed to facilitate greater cardiac rehabilitation utilization warrants future study.

Mentions: Participants consisted of cardiac inpatients. The inclusion criteria at baseline were the following: confirmed acute coronary syndrome diagnosis, patients who had undergone percutaneous coronary intervention or coronary artery bypass graft surgery, and eligibility for cardiac rehabilitation based on indicated cardiac condition.22 The exclusion criteria at baseline for the larger study were the following: participation in cardiac rehabilitation within the past two years, and significant orthopaedic, neuromuscular, visual, cognitive or non-dysphoric psychiatric condition which would preclude cardiac rehabilitation participation. The exclusion criteria at one-year follow-up were the following: unable to contact patient, too ill to participate, or deceased. Figure 1 displays the flow diagram of patient participation. The response rate was 62.1% (2636/4244).
