Background And Purpose:
Cardiovascular disease (CVD) is a major cause of death in the United States. The military are viewed as fit, ready to fight and that jumping out of perfectly good airplane or going to war is a greater risk than CVD. The purpose of this study was to determine reliability and validity of the Cardiovascular Risk Perception Survey (CRPS).
Methods:
A cross-sectional descriptive design was performed, supported by the Health Belief Model. Internal consistency reliability (Cronbach's alpha) and validity (principal component analysis) were examined.
Results:
Fifty-five participants were included in this study. Construct validity of the CRPS was supported by principal component analysis; indicating one scale that measured cardiovascular risk perception. The Cronbach's alpha is reported .865.
Conclusion:
Initial psychometric testing of the CRPS provides evidence for construct validity and internal consistency reliability.
