Validity of the EASYCare Standard 2010 assessment instrument for self-assessment of health, independence, and well-being of older people living at home in Poland

EASYCare Standard 2010 is a brief instrument identifying concerns in health, functional independence, and well-being, from older persons' perspective. It has not previously been validated for self-assessment. Our aim was to determine whether self-assessment (EC1) can give comparable results to an evaluation performed by professionals (EC2), for older people living at home. The study included community-dwelling individuals (aged at least 60 years, n = 100; 67 females) without dementia (abbreviated mental test score [AMTS] above 6). It comprised two assessments (self and professional), including summarising indexes: Independence score [IS], Risk of breakdown in care [RBC], Risk of falls [RF], performed within a period between 1 and 2 weeks. Additionally, during EC1, reference tests of physical and mental function (Barthel Index: 96.3 ± 6.5, Lawton scale: 6.7 ± 2.0, geriatric depression scale: 3.0 ± 2.7, AMTS: 10.2 ± 1.0) were applied to test for concurrent validity. Cohen's kappa values (self-assessment vs. professional assessment) across all EASYCare domains were high (0.89-0.95). Results of all summarising indexes derived from self-assessment correlated strongly with reference tests. No differences were found in IS and RBC between EC1 and EC2 (8.6 ± 12.0 vs. 9.0 ± 12.7 and 1.0 ± 1.1 vs. 1.2 ± 1.4). Results of RF were higher in EC2 (1.0 ± 1.1 vs. 1.1 ± 1.4; p = 0.005), due to a different response to the item "Do you feel safe outside your home?" We conclude that self-assessment with EASYCare Standard in older people without severe functional impairment living at home can deliver valid results, similar to those obtained through professional assessment, thus providing an efficient system for assessment of relatively independent individuals.
