title: Prevalence of mental disorders and trends from 1996 to 2009. Results from the Netherlands Mental Health Survey and Incidence Study-2.
abstract: OBJECTIVE
  To present prevalences of lifetime and 12-month DSM-IV mood, anxiety, substance use and impulse-control disorders from the second Netherlands Mental Health Survey and Incidence Study (NEMESIS-2), and to compare the 12-month prevalence of mood, anxiety and substance use disorders with estimates from the first study (NEMESIS-1).
  
  
  METHODS
  Between November 2007 and July 2009, a nationally representative face-to-face survey was conducted using the Composite International Diagnostic Interview 3.0 among 6,646 subjects aged 18-64. Trends in 12-month prevalence of mental disorders were examined with these data and NEMESIS-1 data from 1996 (n = 7,076).
  
  
  RESULTS
  Lifetime prevalence estimates in NEMESIS-2 were 20.2% for mood, 19.6% for anxiety, 19.1% for substance use disorder and 9.2% for impulse-control disorder. For 12-month disorders, these figures were 6.1, 10.1, 5.6 and 2.1%, respectively. Between 1996 and 2007-2009, the 12-month prevalence of anxiety and substance use disorder did not change. The prevalence of mood disorder decreased slightly but lost significance after controlling for differences in sociodemographic variables between the two studies.
  
  
  CONCLUSIONS
  This study shows that in the Netherlands mental disorders are prevalent. In about a decade, no clear change in mental health status was found.
