飞行员的明尼苏达多项个性测查表因子得分与血型的关系

Relationship between scores on factors in Minnesota multiphasic personality inventory and blood type of pilots

目的:调查现役飞行员群体中明尼苏达多项个性测查表的因子,了解因子T分与血型之间的内在联系。方法:随机抽取2003-03/2005-03到解放军济南军区青岛第二疗养院进行健康疗养的男性飞行员200名,均自愿参加调查。测查明尼苏达多项个性测查表的飞行员T分值,采用主成分分析法提取精神质因子P、神经质因子N、内外向因子I、男子气-女子气因子M、反社会因子A、装好-装坏因子F共6个公因子进行方差极大旋转,得出因子负荷矩阵,将所测人员的血型与因子T分进行相关分析。T分在40～60之间为正常范围,在30～40或60～70之间为偏离倾向,在30分以下或70分以上为病态特征。结果:纳入200名飞行员均符合量表测查标准,均进入结果分析,无脱落。①A型血飞行员中精神质因子均分较高(58.29±8.32),提示具有较高的精神质个性特征;装好-装坏因子均分较高(56.13±9.39),提示心理掩饰程度较差。内外向因子均分较低(44.31±8.96),说明性格特征偏外向。②B型血中神经质因子均分偏低(40.08±9.37),提示具有较高的神经质个性特征。反社会因子均分较高(56.15±8.94),提示社会适应能力偏差;内外向因子均分较高(56.26±9.37),说明性格特征偏内向。③O型血中反社会因子均分较高(58.24±9.21),提示社会适应能力偏低。其他因子分接近标准分(50±10)。④AB型血中精神质和神经质因子分较高(57.26±9.18,58.24±8.59),说明该型血精神质个性特征高而神经质个性特征低;男子气-女子气因子均分低(42.18±8.32),提示男子气倾向;装好-装坏因子均分低(42.59±9.44),提示心理掩饰程度较好。结论:明尼苏达多项个性测查表因子分析能够反映现役飞行员的心理素质,血型不同因子均分也有一定区别,说明人的个性特征与其血型有一定的内在联系。

AIM： To investigate the factors of Minnesota muhiphasic personality inventory （MMPI） in pilots on duty and comprehend the internal relationship between factor T and blood type. METHODS： Two hundred healthy male pilots convalescing in Jinan Military Area Command of Chinese PLA, Qingdao Second Convalescent Hospital from March 2003 to March 2005 were randomly selected and participants all took part in the study voluntarily. T scores of pilots on duty in MMPI were measured by using principal component analysis. Six common factors of P（mind factor）, N（nervousness factor）, I（factor of introversion and extroversion）, M（masculinity- female factor）, A（antisocial factor）, and F（factor of pretending to be good or bad） were extracted to undertake varimax orthogonal rotation, so as to obtain factor loading matrix. A correlation analysis was done between the blood type and T score of subjects . T score between 40 and 60 belonged to normal range, T score in the range of 30- 40 and 60-70 had bias tendency, and those below 30 or above 70 were seen as morbid characters. RESULTS： All 200 pilots included were in accordance with measuring standard and involved in the analysis of results. No subject withdrew from the study. ①Average score of factor P was higher in pilots of type A blood （58.29±8.32）, suggested higher psychotic diathesis characteristics; Average score of factor F was higher in pilots of type A blood （56.13±9.39）, suggested poorer psychological cover-up ability; While the average score of factor I was lower in pilots of type A blood, suggested extroversion. ② Among pilots of type B blood, the average score of factor N was lower（40.08±9.37）, suggested higher neurotic diathesis characteristics; And the average score and factor A were I was higher, suggested less social-adapting ability and introversion respectively. ③ The average scores of factor A was higher in pilots of type O blood （58.24±9.21）, suggested less social-adapting ability; and other factors＇ scores in type O blood pilots were close to standard score（50±10）. ④ In pilots of type AB blood , the average scores of factor P and A were higher（57.26±9.18,58.24±8.59）, suggested more psychotic diathesis characteristics and less neurotic diathesis characteristics respectively. While the average score of factor M was lower（42.18：l：8.32）, indicated more male characteristics ;The average score of factor F was lower （42.59 ±9.44）, indicated better psychological cover-up ability. CONCLUSION： Factor analysis of MMPI can reflect the psychological quality of pilots on duty. Pilots with different blood types have different factor scores, which indicates that there is an internal relationship between personality characteristics and blood type.
