The goal of this pilot study was to explore the relation of beliefs and attitudes about collaborative practices to medical and mental health providers’ training backgrounds. personal characteristics, and perceived characteristics of the organization in which they work. Among medical practitioners, younger providers reported greater belief in the effectiveness of psychosocial intervention than older providers, and female medical providers expressed greater comfort with and belief in a biopsychosocial approach than their male colleagues. Among mental health professionals, results suggest that those out of training longer found collaboration easier. Those mental health providers whose training emphasized collaboration also found collaboration easier and practiced collaboration more frequently than those whose training did not. The discussion highlights these and other findings while acknowledging the limitations of this pilot study.
