Type A behavior and the five-factor model of personality

The hypothesis that people classified as Type A and Type B have different personality profiles based on five major personality factors (Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness) was tested using the Student Jenkins Activity Survey and the Revised NEO Personality Inventory. Results based on discriminant function analysis of data from 243 psychology undergraduates (105 males and 138 females) strongly supported the hypothesis indicating that Type A and Type B groups have significantly different Revised NEO Personality Inventory profiles and that the standardized discriminant function coefficients were large for Agreeableness and Conscientiousness and moderately large for Extraversion.
