摘　　要：[目的]研究中风先兆证临床特征表现。[方法]在文献系统评价的基础上,建立专家调查问卷,预调查信度(Cronbachα系数):0.96和效度(累积方差贡献率)82.22%,分半信度(Guttman Split-half):0.90、分半相关系数:0.87。对资料进行主成分分析降维处理,经球形检验(KMO and Bartlett’s Test),提示可以进行因子分析。[结果]专家问卷调查发放问卷600份,收回问卷588份,失访12份,失访率2%(小于<15%),总体信度0.97和效度73.11%,分半信度0.92、分半相关系数0.91。中风先兆证的临床特征表现如下:病史为冠心病和糖尿病;危险因素为高血压病、年老、环境污染、微循环异常;病因病机为年老体衰、体质不良、气血津液紊乱、脏腑功能失调、腑实壅塞、气候变化、房事不节;证候为气虚血瘀证、痰瘀证、肝风内动证、肝阳上亢证、肾精不足证;症状有倦怠乏力、语言不利、肢体麻木、头昏/头晕/目眩、感觉异常/感觉减退、黑蒙、头胀痛、口角流涎/流涎;舌象有舌淡、舌暗/舌黯/舌暗红/舌暗淡、舌绛红/舌红绛、苔薄白、苔白腻、无苔、苔白;脉象有脉弦滑、脉涩/脉细涩、脉细/脉细弱、脉虚/弱。[结论]以上研究进一步完善了前期文献系统评价的结果,对学会标准的修订具有一定的借鉴价值。[Objective] To study the clinical characteristics of precedent sign of stroke. [Methods] To establish the expert questionnaire based on literature of system evaluation. Pre-survey： reliability （Cronbach alpha） =0.96 ,validity （cumulative % ） =82.22%. Guttman Split- half：0.90, correlation between forms：0.87. Data reduction by principal component analysis and factor analysis, KMO and Bartlett＇s test. [Results] Formal investigation 600 questionnaires, lost 12 parts, dropout rate of 2%, Reliability （Cronbach alpha）=0.97 ,validity （cumu- lative % ）=73.11%. Guttman Split-half： 0.90, correlation between forms： 0.91. Clinical features on premonitory syndromes of stroke： the risk factors included hypertension, age, environment pollution, abnormal microcirculation; etiology and pathogenesis： body failure in eider person, poor physical constitution, turbulence of gas, blood and body fluid, maladjustment of Zang-Fu function climate change; the symp- toms： gas deficiency and blood stasis, phlegm stagnation symptom, wind phlegm symptom, internal moving of liver wind, kidney essence deficiency syndrome; main clinical symptoms for high to low occurrence： dizziness/giddiness/blurred vision, numbness of extremities, las- situde, barylalia, headache, optic atrophy; tongue picture： pale tongue, tongue Black / dark tongue / dark red tongue / tongue, tongue dark crimson / bright red tongue, thin white fur, white greasy moss; pulse picture： taut and slippery pulse, pulse astringent / thready pulse as- tringent, pulse fine / thready pulse, weak pulse. [Conclusion] The above research will improve the results of literature system evaluation and have some reference value to the standards of academic committee.
