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 differentiate 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 (HH)/Emotionality (E)/Conscientiousness (C)/Openness to experience (O) and GAD, whereas there is a negative association between Agreeableness (A)/eXtraversion (X) and GAD. Secondly, age, gender, major, monthly income, HH, 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.
