A Swedish version of the appraisal of Self-Care Agency (ASA) scale

The "Appraisal of Self-care Agency" scale (the ASA scale) is designed to measure self-care agency in accordance with Orem's self-care deficit theory of nursing. The aim of this study was to obtain a reliable Swedish version of the ASA scale by measuring the internal consistency. ASA-A for self-appraisal and ASA-B for appraisal of another were tested with a convenience sample of 52 elderly in-patients and 53 caregivers in six geriatric care units. Cronbach's alpha reliability coefficient was 0.59 for the ASA-A scores, 0.77 for ASA-B scores obtained by caregivers comprising different professions, and 0.87 for scores obtained by registered nurses. Further testing of both validity and reliability is needed if this version of the scale is to be used in nursing research and practice.
