The aim was to develop and psychometrically test the self-care of chronic illness Inventory, a generic measure self-care.Existing measures are disease-specific or behaviour-specific; no exists.Cross-sectional survey.We developed 20-item self-report instrument based on Middle Range Theory Self-Care Chronic Illness, with three separate scales measuring Maintenance, Monitoring, Management. Each is scored separately standardized 0-100 higher scores indicating better self-care. After demonstrating content validity, psychometric testing conducted in convenience sample 407 adults (enrolled from inpatient outpatient settings at five sites United States ResearchMatch.org). Dimensionality confirmatory factor analysis preceded reliability testing.The Maintenance scale (eight items, two dimensions: illness-related health-promoting behaviour) fit well when tested two-factor model. Monitoring (five single factor) fitted well. Management (seven factors: autonomous consulting behaviour), model, adequately. A simultaneous combined set items supported more general model.The inventory adequate validity. We suggest further diverse populations patients illnesses.
