To validate the QUALIDEM, a quality of life measure for people with dementia within residential settings rated by professional caregivers.
In a sample of 202 residents of nursing homes Spearman rank correlations were calculated between the QUALIDEM subscales aand indices of convergent validity and discriminant validity, with dementia severity and need of care, with global QOL scores by the head nurse and family, and with self-report on COOP/WONCA Charts.
The one-method multi-trait matrix showed 90.5% of the correlations to be in support for convergent and discriminant validity. Low to moderate correlations were observed with dementia severity and need of care, confirming that QOL is not merely disease severity. Support for concurrent validity was found in correlations with QOL ratings by the head nurse. The QUALIDEM did not correlate with most of the family ratings or with the COOP/WONCA Charts.
The results of this validation study together with the obtained content validity through the method of construction provide sufficient support for validity of the QUALIDEM to be used for care evaluation and research in residential settings.
验证由专业护理人员对居住机构中痴呆患者生活质量进行评定的工具——痴呆症患者生活质量评定量表（QUALIDEM）。
在一个包含202名养老院居民的样本中，计算QUALIDEM各分量表与收敛效度和区分效度指标、痴呆严重程度和护理需求、护士长及家属评定的总体生活质量得分以及COOP/WONCA图表自评得分之间的斯皮尔曼等级相关性。
单方法多特质矩阵显示，90.5%的相关性支持收敛效度和区分效度。与痴呆严重程度和护理需求呈低到中度相关，证实生活质量不仅仅取决于疾病严重程度。与护士长评定的生活质量得分的相关性表明该量表具有同时效度。QUALIDEM与大多数家属评定得分或COOP/WONCA图表得分无相关性。
本验证研究的结果以及通过构建方法获得的内容效度，为QUALIDEM用于居住机构中的护理评估和研究的效度提供了充分支持。
