Abstract

Introduction: To assess cognitive impairment, self-awareness is an important issue. The Ascertain Dementia 8 questionnaire (AD8) is a brief observation checklist for detecting mild cognitive impairment (MCI) and dementia. After analyzing the reliability and validity of a self-reported Japanese version of the AD8 (AD8-J), we compared self- and informant-reported versions of the AD8-J.

Methods: A total of 93 community residents aged 75 years or older living in Wakuya, Northern Japan, agreed to participate in this study; 35 were rated as Clinical Dementia Rating (CDR) 0 (healthy), 46 as CDR 0.5 (defined herein as MCI), and 12 as CDR 1 or above (dementia, confirmed by the DSM-IV). We examined the reliability and validity using a receiver operating characteristic (ROC) curve. We analyzed the differences between self-reported and informant-reported AD8-J using a repeated measures ANOVA.

Results: The self-reported AD8-J showed a satisfactory reliability (i.e., Cronbach coefficient, α = 0.71; Guttman split half method coefficient = 0.60). For CDR 0 vs. CDR 0.5 or above, the area under the ROC curve was 0.74 and the cutoff score was 1/2, with a sensitivity of 70.7% and a specificity of 65.7%. Analysis of the subscores of AD8 suggested that, from the early stage of dementia, the subjects showed a subjective decline in memory and interest in hobbies/activities, as well as problems with judgment.

Conclusion: It is suggested that the self-reported AD8-J was effective in detecting MCI and dementia. We could use it for detecting MCI and dementia, including in those living alone, in the primary health checkup.

基于确定痴呆8问卷的自我报告认知衰退可能有效地检测社区中的轻度认知障碍和痴呆:Wakuya项目
自我意识是评估认知障碍的一个重要问题。确定痴呆8问卷(AD8)是一份简短的观察检查表,用于检测轻度认知障碍(MCI)和痴呆。在分析了自我报告的日文AD8量表(AD8- j)的信度和效度后,我们比较了自我报告和举报人报告的AD8- j量表。方法:共有93名居住在日本北部Wakuya的75岁及以上社区居民同意参与本研究;35人被评为临床痴呆评分(CDR) 0(健康),46人被评为CDR 0.5(此处定义为MCI), 12人被评为CDR 1或以上(痴呆症,经DSM-IV确认)。我们使用受试者工作特征(ROC)曲线检验信度和效度。我们使用重复测量方差分析分析了自我报告和举报人报告的AD8-J之间的差异。结果:自述AD8-J具有满意的信度(即Cronbach系数,α = 0.71;Guttman二分法系数= 0.60)。CDR 0与CDR 0.5及以上的ROC曲线下面积为0.74,截止评分为1/2,敏感性为70.7%,特异性为65.7%。对AD8分值的分析表明,从痴呆症的早期开始,受试者就表现出主观记忆力和对爱好/活动的兴趣下降,以及判断问题。结论:自述AD8-J对轻度认知损伤和痴呆有较好的检测效果。我们可以用它来检测轻度认知障碍和痴呆症,包括那些独居的人,在初级健康检查中。
