title: Is the Mood Disorder Questionnaire an appropriate screening tool in detecting bipolar spectrum disorder among substance use populations?
abstract: BACKGROUND
  Bipolar spectrum disorder (BSD) has been shown to be difficult to assess in general and is further complicated by the presence of substance use disorder (SUD).
  
  
  OBJECTIVE
  To review the specificity of the Mood Disorder Questionnaire (MDQ) in detecting BSD among substance abusers.
  
  
  METHODS
  A retrospective chart review was conducted using 183 SUD patients who were screened using the MDQ and later assessed by a psychiatrist specializing in BSD.
  
  
  RESULTS
  Among SUD patients scoring positive results on the MDQ for the presence of BSD, the BSD diagnosis could only be confirmed in 23% of the sample by an expert psychiatrist.
  
  
  CONCLUSIONS
  The MDQ reports low specificity in detecting BSD among SUD populations.
  
  
  CONCLUSIONS
  Physicians should question individuals on substance use behaviors if BSD is suspected due to high rates of comorbidity and diagnostic challenges.
