Description: Cardiovascular disease is the leading cause of death in American women; one of every two women die of this disease (Center for Disease Control/National Center For Health Statistics, 1994). Diseases of the heart comprise a significant proportion of cardiovascular deaths. Historically, coronary artery disease has been perceived as a man's disease (Penckofer & Holm, 1990; Vliet, 1992; Wingate, 1991). Perhaps this misperception stems from the lack of cardiovascular research on women, less public education directed toward female-specific cardiac risks, or an inherent bias against women within the health care system resulting in decreased access to diagnostic and therapeutic interventions in cardiology. Whatever the reasons for this misperception, no published studies were found on women's perceptions of cardiac risk factors.

The purpose of this instrument development research was to develop an inventory to measure cardiac risk perceptions among women. The Theory of Reasoned Action (Fishbein & Ajzen, 1975) provided the theoretical framework for the study. The theory's basic premise is that individuals act based on their intentions and that perceptions influence intentions. With valid, reliable measures of women's perceptions of cardiac risks, nursing interventions can focus on changing perceptions of cardiac risks to more accurately reflect actual relationships between risk factors and disease, which in turn may impact behaviors.

The purposive sample consisted of 490 women volunteers who were white (80%) and African-American (20%), 18 years and older, and drawn from medical and non-medical facilities located in three southeastern states. After agreeing to participate, each person completed the Cardiac Risk Perception Inventory (CRPI) and answered demographic and medical questions. Two weeks later, 80 of the 490 volunteers were randomly selected to retake the inventory for the purpose of testing reliability. Sixty-three subjects returned the inventory.

Data analyses included descriptive statistics, t-tests for paired and independent samples, Pearson product moment correlations, and factor analysis. Content validity was established through a literature review and judgement of 15 experts within the field of cardiology. Construct validity was established through factor analysis. Pearson product moment correlations were significant between 14 cardiac risk factors and women's overall perception of risk. Test-retest reliability identified 13 cardiac risk factors having significant reliability coefficients. Preliminary results indicate the Cardiac Risk Perception Inventory is valid and reliable measure of women's perception of risk for developing coronary artery disease.
