Our research group focuses on personality and the connection with psychopathology (especially personality pathology)across the life span. Both theoretical and measurement models, as well as clinical practice and treatment, are examined. The research is grouped around a number of subjects such as dimensional approaches, life course phases, information processing, test validation (eg APD-IV, PID-5 etc.), connection with psychopathology, somatic problems and forensic aspects (e.g. psychopathy).
