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.
本文描述了一种能力评估工具（AAI）的心理测量特性，该工具旨在评估患有与痴呆症相关的认知障碍（CI）的老年人的自我护理、社交、互动和解释能力。样本包括112名患有CI的机构养老男性和60名未患CI的机构养老男性。AAI的心理测量评估表明：（a）在重测（皮尔逊r值范围为0.93 - 0.99）、评分者间（皮尔逊r值范围为0.95 - 0.99）和内部一致性评估（克朗巴赫α系数为0.90 - 0.98）方面，以及通过验证性因素分析，它都是可靠的；（b）在内容效度（CVI为87.3%）、同时效度（在伦敦老年精神病评定量表[LPRS]上，皮尔逊r相关性范围为 - 0.67至 - 0.80，在功能评估阶段量表[FAST]上为 - 0.76至 - 0.85）以及结构效度方面是有效的，患有CI和未患CI的受试者之间存在显著差异（t值范围为5.13 - 9.30）。AAI是一种可靠且有效的工具，可用于提供评估数据。
