title: Reliability and validity of the Kessler 10 and Patient Health Questionnaire among injecting drug users.
abstract: OBJECTIVE
  To examine the reliability and validity of the Kessler 10 (K10) and the Patient Health Questionnaire (PHQ) in a sample of injecting drug users (IDUs).
  
  
  METHODS
  Participants were 103 IDUs with a current substance use disorder accessing a needle and syringe programme. Presence of mental health disorders was assessed using the Mini International Neuropsychiatric Interview (MINI).
  
  
  RESULTS
  Both the K10 and PHQ had high levels of internal consistency and concurrent validity. Individuals with a positive screen on the K10 were ten lines more likely to have a current affective disorder, while those with a positive PHQ screen had nearly 14 times the risk.
  
  
  CONCLUSIONS
  The K10 and PHQ are recommended as brief screening and diagnostic tools for current affective disorders among IDUs.
