Popis:	In this article the psychometric properties of an Abilities Assessment Instrument (AAI), developed to assess the self-care, social, interactional and interpretive abilities of older people with cognitive impairment (CI) related to dementia, are described. The sample consisted of 112 institutionalized older men with CI and 60 institutionalized older men without CI. The psychometric evaluation of the AAI indicated that: (a) it is reliable in terms of test-retest (Pearson’s r range .93-.99), interrater (Pearson’s r range .95-.99), and internal consistency evaluations (Cronbach’s alpha .90-.98), as well as through confirmatory factor analysis; and (b) that it is valid with respect to content validity (CVI 87.3%), concurrent validity (Pearson’s r correlations ranging from -.67-.80 on the London Psychogeriatric Rating Scale [LPRS], and from -.76-.85 on the Functional Assessment Stages Scale [FAST]), and construct validity with significant differences between subjects with and without CI (t values ranging from 5.13 -9.30). The AAI is a reliable and valid instrument that can be used to provide assessment data.
