工作背景：本研究的目的是评估的有效性，可靠性和反应性的瑞典翻译的生活质量在晚期痴呆症（EQUID）Scale.Method：共169名老年居民在19个痴呆症特殊护理单位在8个长期护理设施在哥德堡城市地区参加了这项研究。结果：问卷的内部一致性信度（Cronbach 'salpha系数为0.74）、被试间评分者信度（0.69）和重测信度（0.86）均达到了较好的水平。正如假设的那样，EPOID评分也与其他生活质量（QoL）指数（标准有效性）以及精神活性药物的使用和认知障碍测试（临床有效性）相关。问卷的响应性也是acceptable.Conclusions：重要的临床决策可能来自感知生活质量的影响，这是至关重要的生活质量数据是可靠的，有效的和敏感的变化。我们的评估的心理测量学特性的瑞典EPOMID表明，它令人满意地满足需要的工具，以评估生活质量在瑞典的晚期痴呆症，在广泛的设置和应用。
Background: The aim of the present study was to evaluate the validity, reliability and responsiveness of a Swedish translation of the Quality of Life in Late-Stage Dementia (QUALID) Scale.Method: A total of 169 elderly residents at 19 dementia special care units in eight long-term care facilities in the Gothenburg city region participated in the study. Assessments were made by 107 proxy informants.Results: Results showed satisfactory levels of internal consistency reliability (Cronbach's alpha coefficients 0.74), acceptable inter-rater reliability between informants (0.69), and high test-retest reliability (0.86). As hypothesized, QUALID scores were also associated with those from other quality-of-life (QoL) indices (criterion validity), as well as with use of psychoactive drugs, and with tests of cognitive impairment (clinical validity). The responsiveness of the questionnaire was also acceptable.Conclusions: As important clinical decisions may derive from perceived QoL effects, it is vital that the QoL data be reliable, valid and sensitive to change. Our evaluations of the psychometric properties of the Swedish QUALID indicate that it satisfactorily meets the need for an instrument to assess QoL in late-stage dementia in Sweden, in a wide range of settings and applications.
