摘　　要：目的调查认知功能正常中老年人对于画钟测验（CDT）条目组成的认可度，为编制CDT评分标准提供参考。方法横断面分析自2014年6月至2014年12月在北京市西城区月坛社区招募的264例认知正常中老年人，选择国内外已有CDT评分的26个条目组成调查问卷。请被试评价是否同意。采用Pearson相关分析检测与被试年龄、受教育程度相关的条目。结果26个条目中有5项与被试年龄、教育程度呈相关关系。被试完全同意率超过50％、不同意率低于20％的有12项，去掉其中与受教育程度显著相关的1项，增加对认知功能变化敏感的1项，生成新的CDT评分条目共12项。结论新12项评分条目可能更适用于我国中老年人的认知功能筛查．可进一步进行信度与效度验证以应用于临床。Objective To investigate the knowledge and recognition of middle aged and elderly cognitive normal people in clock drawing test （CDT） and determine the items of CDT. Methods Two hundred and sixty four middle aged and elderly cognitive normal people from community were involved in the cross-sectional study. The questionnaire was comprised of 26 items scoring in CDT in literature. Each item was rated by subjects as complete agreement, partial agreement or disagreement. Pearson correlation analysis was used to analyze the related items of age and education degree. Results There were 5 items significantly related with age and education. Twelve items enjoyed complete agreement of more than 50% and disagreement lower than 20%. The new scoring system was composed of 12 items, including the 12 complete agreement items excepted one which was significantly related to age and education, and one item that was proved to be sensitive to cognitive impairment. Conclusion The new scoring system with 12 items for CDT may be suitable in screening cognitive impairment with high identity, and further investigation about the validity and reliability should be conducted.
