DSM-5 to include the Big 5

The Five Factor Model in the DSM-5

The current Axis II disorders will be replaced by a mixture of continuously-rated personality disorder types (carrying forward psychopathy, avoidant, borderline, obsessive-compulsive, and schizotypal) and 6 personality traits. According to the rationale, four of the traits are pathological versions of 4 of the Big Five (Openness/Intellect apparently doesn’t have a pathological extreme).
