[Psychiatric morbidity among adults in The Netherlands: the NEMESIS-Study. I. Objectives, design and methods. Netherlands Mental Health Survey and Incidence Study].
OBJECTIVE
To determine prevalence, incidence and course of psychiatric disorders in non-institutionalised Dutch adults.


METHODS
Prospective and cross-sectional.


METHODS
Trimbos Institute, Utrecht, the Netherlands.


METHODS
A multistage, stratified random sampling procedure was used to obtain a sample of 7076 adults (18-64 years). Respondents were interviewed throughout 1996 in their homes. The main diagnostic instrument was the 'Composite international diagnostic interview' (CIDI), designed to assess lifetime prevalence of mental disorders according to Diagnostic and statistical manual of mental disorders, 3rd revised edition (DSM-III-R). The diagnostic categories were: affective disorders, anxiety disorders, eating disorders, schizophrenia and other non-affective psychoses, and substance use disorders (dependence and abuse). The sample was weighted towards national census data on sex, age, marital status and urbanicity.


RESULTS
The results of the first measurement (1996) will be described in the next article (1997:2353-60). The response rate was 64.2%. There were no indications that the psychiatric morbidity of non-respondents differed from respondents. The same respondents will be interviewed again after 12 (1997) and after 36 months (1999).
