早期发现老年痴呆症的一个潜在测试是老年人认知能力下降的知情人问卷（IQCODE），该问卷基于老年人知情人提供的有关老年人与痴呆症相关的日常认知功能变化的信息。本研究旨在对修订后的智商量表（32个条目）进行修订和信效度评价。该研究包括两种评估痴呆症的方法：由临床医生进行的DSMIV诊断和对IQCODE做出反应的知情者。研究对象为200对老年人和他们的被调查者，他们都在Ramathibodi医院的老年门诊就诊。改良IQCODE的最佳临界值为3.42，敏感性为90%，特异性为95%。阳性预测值、阴性预测值和准确度分别为0.94、0.90和0.92。IQCODE条目具有较高的内部一致性。IQCODE与老年人的年龄有关，但与他们的性别和教育水平无关，也与被调查者的人口统计学特征无关。因此，IQCODE可作为泰国痴呆症的替代筛查试验，具有可接受的灵敏度和特异性。这个工具可能是有用的痴呆症筛查在社区和老年诊所的早期发现疾病。
A potential test for early detection of dementia in the elderly is the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE), which is based on information from the informant for the elderly about the changes of the elderly in everyday cognitive functioning associated with dementia. The present study aimed to modify and assess the reliability and validity of the modified IQCODE consisting of 32 items. The study consisted of two methods of assessing dementia: DSMIV diagnosis carried out by clinicians, and informants responding to the IQCODE. The subjects were 200 pairs of elderly subjects and their informants who visited the Geriatric Clinic, Ramathibodi Hospital. The optimal cutoff score on the modified IQCODE was 3.42, with 90% sensitivity and 95% specificity. The positive predictive values, negative predictive values, and accuracy were 0.94, 0.90, and 0.92, respectively. The IQCODE items had high internal consistency. The IQCODE associated with the elderly person's age, but not with their gender and educational level; nor were they associated with the demographic characteristics of the informant. Therefore, the IQCODE could be used as an alternative screening test for dementia in Thailand with acceptable sensitivity and specificity. This tool may be useful for dementia screening in the community and the geriatric clinic for early detection of disease.
