• Description:
  Background: Individuals with coronary heart disease (CHD) are routinely instructed to engage in self-care behaviors conceptualized as a decision-making process involving the choice of activities that maintain stability (self-care maintenance) and the response to symptoms when they occur (self-care management). Yet, there are no instruments available to measure self-care in this population. The purpose of this study was to test the construct validity of the Self-Care of Chronic Angina Index (SCCAI). Methods: A convenience sample of 196 adults with CHD (e.g., history of myocardial infarction, angina) completed: I) SCCAl, 2) the Medical Outcomes Study General Adherence Scale (GAS), and 3) Decision Making Competency Inventory (OMCI). Exploratory factor analysis with geomin rotation identified the item structure. Comparative fit index (CF1) Root Mean Square Error of Approximation (RMSEA) and Standardized Root Mean Square Residual (SRMR) were used to judge model fit. Speanuan's correlations (rho) tested associations between self-care and adherence (GAS) and decision-making (i.e, awareness, self-appraisal, and autonomy domains of the DCMl). Results: 64% of the sample was male; mean age was 64 +/- 10 years; mean duration of CHD was 7 +/- 10 years. The best fit exploratory factor model involved four scales (CFI = 0.96, RMSEA = 0.05, SRMR = 0.07). Keeping appointments, taking ASA or other blood thinners, physical activity, taking mediations as prescribed, using a system for medications, fruit and vegetable consumption, and smoking were linked factors we called self-care maintenance (a = .67). Taking nitroglycerine, calling the MDIRN, and taking it easy were linked responses to symptoms we called prescribed behaviors (a = .70). Quickly recognizing symptoms, slowing down, and judging if a remedy worked were linked responses we called self-care management (a = .55). Six self-efficacy items and asking for low fat food while eating out were associated factors we called self-care confidence (a = .90). Self-care maintenance behaviors (rho = .45), prescribed behaviors (rho = .22) and self-care confidence (rho = .33) were associated with adherence (all p < 0.05). Self-care management behaviors were associated with awareness (rho = -.24), self-appraisal (rho = .32), and autonomy (rho = .37) (all p < 0.05). Conclusion: These findings support the conceptual basis of self-care in patients with CHD and suggest that the SCCAI may be used to measure self-care maintenance and management among adults with CHD.
