title: The mood disorder questionnaire improves recognition of bipolar disorder in psychiatric care.
abstract: BACKGROUND
  We investigated our translation of The Mood Disorder Questionnaire (MDQ) as a screening instrument for bipolar disorder in a psychiatric setting in Finland.
  
  
  METHODS
  In a pilot study for the Jorvi Bipolar Study (JoBS), 109 consecutive non-schizophrenic psychiatric out- and inpatients in Espoo, Finland, were screened for bipolar disorder using the Finnish translation of the MDQ, and 38 of them diagnostically interviewed with the SCID.
  
  
  RESULTS
  Forty subjects (37%) were positive in the MDQ screen. In the SCID interview, twenty patients were found to suffer from bipolar disorder, of whom seven (70%) of ten patients with bipolar I but only two (20%) of ten with bipolar II disorder had been previously clinically correctly diagnosed. The translated MDQ was found internally consistent (alpha 0.79) and a feasible screening tool.
  
  
  CONCLUSIONS
  Bipolar disorder, particularly type II, remains commonly unrecognized in psychiatric settings. The Mood Disorder Questionnaire is a feasible screen for bipolar disorder, which could well be integrated into psychiatric routine practice.
