To evaluate the scalability and reliability of Qualidem, a quality of life observation instrument rated by professional caregivers of persons with mild to very severe dementia living in residential settings.
Data from four field surveys in the Netherlands were used. The instrument consists of nine subscales for mild to severe dementia; of which six can be applied in very severe dementia. The Mokken scaling model was used to compute scalability and reliability coefficients for each subscale and dementia group.
Seven hundred fifty nine persons with mild to severe dementia and 214 persons with very severe dementia residing in 36 nursing homes and 4 homes for the elderly were included. In general, the subscales for the mild to severely demented group were scalable and (moderate) sufficiently reliable; the results confirmed the results of previous research to develop Qualidem. For the very severe demented group, four out of six subscales were scalable (Care relationship, H = 0.56; Positive affect, H = 0.55; Restless tense behavior, H = 0.42; and Social isolation, H = 0.34); they were also sufficiently reliable to measure quality of life (0.57 ≤ ρ ≤ 0.82). From the other two measured subscales, Social relations was considered not scalable (H = 0.26) and Negative affect was scalable (H = 0.36), but insufficiently reliable (ρ = 0.40).
Qualidem is an easy to administer and overall moderately sufficient reliable rating scale that provides a quality of life profile of persons with mild to even very severe dementia living in residential settings.
评估 Qualidem 的可扩展性和可靠性，Qualidem 是一种由居住在住宅环境中的轻度至重度痴呆患者的专业护理人员评定的生活质量观察工具。
使用来自荷兰的四项现场调查的数据。该仪器由九个用于轻度至重度痴呆的子量表组成；其中六个可用于非常严重的痴呆症。采用 Mokken 评分模型计算每个子量表和痴呆症组的可扩展性和可靠性系数。
共纳入 36 家养老院和 4 家养老院的 759 名轻度至重度痴呆症患者和 214 名非常严重痴呆症患者。一般来说，轻度至重度痴呆组的子量表是可扩展的（中度）且具有足够的可靠性；结果证实了先前开发 Qualidem 的研究结果。对于非常严重的痴呆组，六个子量表中的四个是可扩展的（护理关系，H = 0.56；积极情绪，H = 0.55；不安紧张行为，H = 0.42；和社会隔离，H = 0.34）；它们也具有足够的可靠性来衡量生活质量（0.57 ≤ ρ ≤ 0.82）。从另外两个测量的子量表来看，社会关系被认为是不可扩展的（H = 0.26），而消极情绪是可扩展的（H = 0.36），但可靠性不足（ρ = 0.40）。
Qualidem 是一种易于管理且总体上中度可靠的评分量表，可为居住在住宅环境中的轻度至重度痴呆患者提供生活质量概况。
