Abstract

The purpose of this study was to identify the number of personality factors in Chinese adolescents using the Chinese Revised NEO Personality Inventory (NEO-PI-R) and to determine whether blood type is associated with personality. It is widely accepted by psychologists that the five-factor model can provide an adequate representation of adult personality dimensions, but there is less agreement on the number of factors observable in adolescence. A total of 3,396 11th graders from the city of Kaohsiung, Taiwan completed the Chinese NEO-PI-R. Principle component analysis with varimax rotation showed five factors of personality in these Taiwanese adolescents, which clearly replicates the five-factor structure seen in adults.

Results from earlier researchers who investigated an association between blood type and personality were mixed. However, studies based on the five-factor model (Cramer & Imaike, 2002; Rogers & Glendon, 2003) reported no significant relationship between blood type and personality. Our study is the third published article to examine this relationship using the five-factor model. Of the 3,396 participants, 2,681 students who reported their blood types were included in the analysis. A sub-sample of 176 students was given ABO blood group tests to evaluate the accuracy of blood type recall. Multiple linear regression analysis showed no significant relationship between blood type and personality except for Type AB females who scored lower than Type O females did on the Conscientiousness domain. However, this effect might be due to chance because of the small sample size for Type AB females (78). These results are supported by MANOVA analysis which found no significant effect. These suggest that personality is not related to blood type. We also investigated the relationships between personality factors and other covariates, such as BMI and academic achievement. The interpretation of these results must be cautious because of potential Type I errors in multiple significance testing. We found academic achievement to be positively related to Openness and negatively related to Extraversion. BMI was inversely related to Extraversion in females only.
