Although coronary heart disease (CHD) requires a significant amount of self-care, we located no existing self-care instruments specific for this population. So, we used the Self-Care of Chronic Illness theory to develop the Self-Care of Coronary Heart Disease Inventory (SC-CHDI). We developed a 22-item measure of self-care maintenance, management, and confidence appropriate for persons with stable CHD and tested it in a convenience sample of adults. In that publication (Dickson VV, Lee CS, Yehle KS, Mola A, Faulkner KM, Riegel B. Psychometric Testing of the Self-Care of Coronary Heart Disease Inventory (SC-CHDI), Research in Nursing & Health, 2017: 40(1), 15-22. DOI 10.1002/nur.21755) we demonstrated factorial validity with confirmatory factor analysis, convergent validity with the Medical Outcomes Study MOS-SAS Specific Adherence Scale and the Decision Making Competency Inventory (DMCI). Cronbach alpha and factor determinacy scores (FDS) were calculated to assess reliability.

The published findings support the conceptual basis of self-care in patients with CHD as a process of maintenance that includes both consultative and autonomous behaviors, and management with symptom awareness and response. This instrument is available for use as a measure of self-care in this population.
