title: [Design of the general population study NEMESIS-2: Netherlands Mental Health Survey and Incidence Study-2].
abstract: BACKGROUND
  The longitudinal epidemiological population study NEMESIS-2 (Netherlands Mental Health Survey and Incidence Study-2) replicates the first study conducted from 1996 to 1999, and expands it by adding new subjects such as impulse-control disorders.
  
  
  OBJECTIVE
  To describe the aims and design of <span class="abbreviation">nemesis</span>-2, particularly of its first round of measurements, to provide up-to-date figures on prevalence, incidence, course and consequences of mental disorders and associated factors, and to study trends in the mental health of the population aged 18-64 years and the use these people make of psychiatric services.
  
  
  METHODS
  Face-to-face interviews were conducted (November 2007-July 2009) by means of the Composite International Diagnostic Interview 3.0.
  
  
  RESULTS
  The response was 65.1% (n = 6646). Respondents were reasonably representative for the population, but young persons were somewhat underrepresented. Two follow-up rounds of measurements are planned with three-year intervals between the rounds. The second round of measurements began in November 2010.
  
  
  CONCLUSIONS
  A qualitatively good dataset was built up. This will allow several mental health topics to be studied in the future.
