title: Decision making in psychiatric civil commitment: an experimental analysis.
abstract: OBJECTIVE
  Legislation in Canada and the United States that was intended to decrease the use of civil commitment has resulted in a paradoxical increase in involuntary hospital admissions. To elucidate the reasons for this increase, this study was designed to assess the relative importance of various factors involved in the decision to commit a patient.
  
  
  METHODS
  All psychiatrists in Ontario were sent a questionnaire asking them to make commitment decisions based on hypothetical case vignettes. Four factors were systematically varied in the vignettes: the patients' legal commitability, clinical treatability, alternative resources, and psychotic symptoms. Completed questionnaires, with three vignettes each, were returned by 495 respondents.
  
  
  RESULTS
  All four variables were statistically significant in the expected direction; legal commitability (i.e., dangerousness to self and/or others, inability to care for self) and presence of psychotic symptoms accounted for the majority of the variance in the final decision to commit.
  
  
  CONCLUSIONS
  These results suggest that psychiatrists in Ontario rely primarily on legally mandated factors (i.e., psychosis and dangerousness) in making their decisions to commit, although a considerable amount of individual variation is also evident.
