西安市小学生ABO血型与性格的相关性

Correlation Between ABO Blood Group and Personality of Primary School Students in Xi'an

目的求证小学生血型与性格的相关性。方法于2020年10月-11月在西安市城区所属的未央区、莲湖区、新城区、碑林区、雁塔区、灞桥区、高新区7个区各随机抽取1个学校,每个学校抽取4~6年级各2个班共2100人,采用龚耀先修订的艾森克个性问卷(EPQ)(儿童用)和自编一般情况问卷进行调查。分析儿童的血型分布、EPQ个性中P(精神性)、E(向性)、N(情绪)、L(掩饰性)4个维度的得分,及其两者间的关系。结果问卷回收后剔除血型未填写或项目不全者342人,EPQ中L维度标准分≥70分者52人,最终有效问卷1706份,问卷回收合格率83.71%。西安市9~15岁小学生不同年龄组、不同性别A、B、AB、O血型分布比较,差异无统计学意义(P>0.05);不同性别A、B、AB、O四种血型间的P、E、N、L维度中每个维度分比较,差异无统计学意义(P>0.05);不同血型间男童或女童性格中P、E、N、L维度的人数分布比较,差异无统计学意义(P>0.05)。结论血型与性格之间不存在必然联系,血型性格学说没有科学依据。
