Until now, there has been no instrument to measure the quality of life (QoL) of patients with severe dementia in Japan. The purpose of this study was to translate the Quality of Life in Late-stage Dementia Scale and to evaluate the reliability and validity of the Japanese version (QUALID-J).
We translated the Quality of Life in Late-stage Dementia into Japanese with permission from the original authors. We assessed a total of 70 dementia patients (14 men, 56 women; mean age: 87.4 ± 7.9 years) with the QUALID-J.
The test-retest and inter-rater reliability of the QUALID-J was significant. With regard to the criterion-related validity, the correlation coefficient for the total score between the QUALID-J and Quality of Life for Alzheimer's Disease was -0.287 (P < 0.05). With regard to the construct validity, the QUALID-J total score was significantly correlated with the Mini-Mental State Examination (ρ = -0.346, P < 0.01), the Cognitive Test for Severe Dementia (ρ = -0.323, P < 0.01), the Neuropsychiatry Inventory-Nursing Home version (ρ = 0.386, P < 0.01), the Cornell Scale for Depression in Dementia (ρ = 0.262, P < 0.05), the Physical Self-Maintenance Scale (ρ = -0.283, P < 0.05), and the Pain Assessment in Advanced Dementia (ρ = 0.530, P < 0.01).
The results of this study showed that the QUALID-J is a reliable and valid quality of life scale for severe dementia. This scale finally enables an adequate assessment of the quality of life of patients with severe dementia in Japan, which has not been possible until now.
到目前为止，日本尚无用于测量重度痴呆患者生活质量（QoL）的工具。本研究的目的是翻译《晚期痴呆生活质量量表》并评估其日语版（QUALID-J）的信度和效度。
我们在获得原作者许可后将《晚期痴呆生活质量量表》翻译成日语。我们使用QUALID-J对总共70名痴呆患者（14名男性，56名女性；平均年龄：87.4±7.9岁）进行了评估。
QUALID-J的重测信度和评分者间信度显著。关于效标关联效度，QUALID-J总分与《阿尔茨海默病生活质量量表》总分的相关系数为-0.287（P<0.05）。关于结构效度，QUALID-J总分与简易精神状态检查表（ρ=-0.346，P<0.01）、重度痴呆认知测试（ρ=-0.323，P<0.01）、《神经精神科问卷-养老院版》（ρ=0.386，P<0.01）、《康奈尔痴呆抑郁量表》（ρ=0.262，P<0.05）、《身体自我维持量表》（ρ=-0.283，P<0.05）以及《晚期痴呆疼痛评估量表》（ρ=0.530，P<0.01）显著相关。
本研究结果表明，QUALID-J是一种用于重度痴呆的可靠且有效的生活质量量表。该量表最终能够对日本重度痴呆患者的生活质量进行充分评估，而这在以前是无法做到的。
