尽管人们对认知概念的复杂性有了越来越多的了解，但目前还没有评估痴呆症不同认知领域的工具。本研究以201例痴呆症患者及其家庭照顾者为研究对象，探讨了多维认知评定量表(ASPIDD)的心理测量特性。Cronbach‘s Alpha较高(Alpha=0.87)，显示出良好的内部一致性。校正后的条目-总分相关系数的均值为中等。ASPIDD提出了一个结构明确的四因素解决方案：对日常生活活动、认知功能和健康状况、情绪状态以及社会功能和关系的认识。功能障碍与ASPIDD总分、日常生活活动缺乏意识、认知功能、情绪状态呈正相关。照顾者的负担与ASPIDD总分和对认知功能的不了解有关。结果表明，ASPIDD确实是一个多维的量表，为痴呆症患者对疾病的认识提供了一个可靠的衡量标准。进一步的研究应该探索与痴呆症意识的不同维度相关的危险因素。
Despite the growing understanding of the conceptual complexity of awareness, there currently exists no instrument for assessing different domains of awareness in dementia. In the current study, the psychometric properties of a multidimensional awareness scale, the Assessment Scale of Psychosocial Impact of the Diagnosis of Dementia (ASPIDD), are explored in a sample of 201 people with dementia and their family caregivers. Cronbach's alpha was high (alpha = 0.87), indicating excellent internal consistency. The mean of corrected item-total correlation coefficients was moderate. ASPIDD presented a four-factor solution with a well-defined structure: awareness of activities of daily living, cognitive functioning and health condition, emotional state, and social functioning and relationships. Functional disability was positively correlated with total ASPIDD, unawareness of activities of daily living, cognitive functioning, and with emotional state. Caregiver burden was correlated with total ASPIDD scores and unawareness of cognitive functioning. The results suggest that ASPIDD is indeed a multidimensional scale, providing a reliable measure of awareness of disease in dementia. Further studies should explore the risk factors associated with different dimensions of awareness in dementia.
