title: Changes in the rate of diagnosis of major depression in adolescents following routine use of a depression rating scale.
abstract: OBJECTIVE
  Because major depression in adolescents often goes undiagnosed, it is useful to establish whether clinicians' rates of making this diagnosis in a specialist adolescent mental health service change when a self-rating depression scale is routinely administered.
  
  
  METHODS
  A retrospective, naturalistic study examining the rate of diagnosis of major depression in a mental health service between 1993 and 1997. The intervention was the administration of the Center for Epidemiological Studies Depression Scale (CES-D)prior to initial assessment from September 1995 onwards. The proportion of clinical diagnoses of DSM-III-R or DSM-IV major depression was the outcome measure. Age, gender, ratings of depression and other confounding variables were used to control for changes in patient population over time.
  
  
  RESULTS
  One thousand three hundred and ten adolescents aged 12 to 17 years assessed between 1993 and 1997 were included. After taking into account potential confounders, diagnosis of major depression was 2.8 times (95% confidence interval 1.8, 4.3) as likely when the CES-D was in use. Increase was more marked when adolescents were more disturbed overall. There was no evidence suggesting this was due to changes in diagnostic practices or in the patient population.
  
  
  CONCLUSIONS
  Availability to clinicians of a self-rating depression scale completed prior to assessment was associated with an increase in the frequency of diagnosis of depression in a specialist mental health service for adolescents.
