Personality Disorders Study (CLPS)
CLPS is a multi-site NIMH-funded study that sampled patients with borderline, avoidant, obsessive-compulsive, schizotypal PD or major depression without a personality disorder, who were followed with yearly assessments for 10 years to establish the course of personality disorder.
