The purpose of this study was to investigate the factor structure and
psychometric properties of the Cardiac Rehabilitation Barriers Scale (CRBS).
DESIGN : 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 alpha = .89), logistical factors (eigenvalue = 5.83,
Cronbach's alpha = .88), work/time conflicts (eigenvalue = 3.78, Cronbach's alpha
= .71), and comorbidities/functional status (eigenvalue = 4.85, Cronbach's alpha
= .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.
