Personality traits that associated with generalized anxiety disorder among PhD students

There is an association between personality traits and generalized anxiety disorder (GAD). In order to differ-entiate the association between various personality traits and GAD, a survey was conducted among PhD students in northern China (mainland). Three conclusions could be drawn with the help of regression analysis. At first, there is a positive association between Honesty-Humility (H-H)/Emotionality (E)/Conscientiousness (C)/ Openness to experience (O) and GAD, whereas there is a negative association between Agreeableness (A)/eX-traversion (X) and GAD. Secondly, age, gender, major, monthly income, H-H, E, X, A, C and O could explain a 21.80 % variance in GAD. Thirdly, E and C are two robust factors that associated with GAD among PhD students.
