早期痴呆的诊断是通过简单的筛查试验来辅助的;患者和被调查者的特征如年龄、性别和受教育程度可能会使评分产生偏差。目的评估全科医生认知评估（GPCOG）是否会因患者和被调查者的特征而产生偏差。GPCOG是一种用于检测认知障碍的简短筛查工具，包括患者认知测试和向被调查者提问。设计，67名全科医生招募了连续的患者（与告密者）。方法采用GPCOG、剑桥老年精神障碍检查认知量表（CAMCOG）、认知功能障碍量表（MRD）、认知功能障碍量表进行老年抑郁量表（GDS）和SF-12健康调查（SF-12），收集人口统计学数据，并做出痴呆的共识DSM-IV诊断。患者和线人的特点和GPCOG措施之间的关系进行了检查，使用皮尔逊相关性和线性回归analysis.Results有相关性，在GPCOG患者的分数与年龄，教育和抑郁症的分数，但回归分析只有年龄与GPCOG患者部分。GPCOG-线人部分是免费的bias.Conclusions的GPCOG在初级保健中使用的优势，是免费的许多偏见常见于其他规模。版权所有（C）2064约翰威利父子有限公司
Background Early dementia diagnosis is aided by the use of brief screening tests; scores can be biased by patient and informant characteristics such as age, gender and education.Objective To assess whether the General Practitioner's Assessment of Cognition (GPCOG), a brief screening tool for detecting cognitive impairment comprising a patient cognitive test and questions to an informant, is biased by patient and informant characteristics.Design, Sixty-seven general practitioners recruited consecutive patients (with informants). Patients were subsequently assessed by a research psychologist, and DSM-IV diagnoses assigned following a case-conference.Setting Primary Care.Subjects Two hundred and eighty three home-dwelling individuals, 11.3% of whom were aged 50-74 years with suspected memory problems and the rest aged 75 or more.Methods The GPCOG, Cambridge Mental Disorder of the Elderly Examination cognitive scale (CAMCOG), Geriatric Depression Scale (GDS), and the SF-12 Health Survey (SF-12) were administered and demographic data were collected and consensus DSM-IV diagnoses of dementia made. Relationships between patient and informant characteristics and the GPCOG measure were examined using Pearson correlations and linear regression analyses.Results There were correlations in GPCOG-patient scores with age, education and depression scores but on regression analysis only age was associated with the GPCOG-patient section. The GPCOG-informant section was free of bias.Conclusions The GPCOG has advantages for use in primary care and is free of many biases common in other scales. Copyright (C) 2064 John Wiley Sons, Ltd.
