Type A personality portrayed higher levels of agreeableness, conscientiousness, cooperativeness, and self-directedness. Specifically, the sociability, empathy, and cooperativeness scales of the JPI-R measure adroitness. These styles can be assessed on axes of cooperativeness to assertiveness. Cloninger argued that these domains are captured by self-directedness, cooperativeness, and self-transcendence respectively. Cooperativeness was inversely related to the Aggression-hostility scale. The third cluster is the emotional cluster, which contains the empathy, anxiety, and cooperativeness scales. Cloninger's research found that low cooperativeness is associated with all categories of personality disorder.
