title: Roles of psychiatrists and other professionals in mental healthcare: results of a formal group judgement method among mental health professionals.
abstract: BACKGROUND
  Professional boundaries between psychiatrists and other mental health professionals are difficult to set. Empirical evidence for the distribution of diagnostic and treatment tasks among professionals is lacking.
  
  
  OBJECTIVE
  This study examines the 'collective sense of the profession' about the relationship between patient characteristics and the contribution of tasks by disciplines.
  
  
  METHODS
  An adapted RAND appropriateness method was used. Eighty-six professionals judged 77 case descriptions of psychiatric patients on the contribution to diagnostic and treatment tasks of eight selected disciplines.
  
  
  RESULTS
  In two multi-level models the variance explained by the judges' characteristics was 3.7% for diagnostic tasks and 4.5% for treatment tasks. The variance explained by the patient characteristics was zero for diagnostic and 0.5% for treatment tasks. The variance explained by the indicated disciplines was 36.8% for diagnostic and 12.6% for treatment tasks.
  
  
  CONCLUSIONS
  The collective sense of the profession on the contribution of psychiatrists to mental healthcare is unambiguous but not related to patient characteristics. It seems to be based on an a priori ranking order of disciplines.
