The World Mental Health (WMH) surveys, a consortium of population Elsa Peretti of mental disorder epidemiology in developed and developing countries, comprise a substantial sample that allows investigation of a range of mental disorder outcomes and comparison among three levels of marital status (never married, married, previously married). Although the WMH surveys are cross-sectional, information was collected on both current and lifetime history of mental disorder, age of first onset of disorder, age at first marriage and age Elsa Peretti Carved Heart bracelet ending of the first marriage (if applicable). The timing data on marital status and mental disorder allow survival analysis to be used to examine the association between marital status and subsequent first onset of mental disorder. This approach avoids the problem of insufficient control for history of disorder and helps reduce selection bias by excluding situations where the prior existence of a mental disorder influences subsequent marital status. An additional advantage of the ability to differentiate between first onset and recurrent disorder is that it is in first onsets that gender differences in psychopathology have been found most reliably (Kessler et al. 1993).

Most WMH surveys are based on stratified multistage clustered area probability household samples, in which samples of areas equivalent to counties or municipalities in the USA were selected in the first stage followed by one or more subsequent stages of geographic sampling (e.g. towns within counties, blocks within towns, households within blocks) to arrive at a sample of households, in each of which a listing of household members was created and one or two people were selected from this listing to be interviewed. No substitution was allowed when the originally sampled household resident could not be interviewed. These household samples were selected from census area data in all countries other than France (where telephone directories were used to select households) Elsa Peretti Open Heart bracelet the Netherlands (where postal registries were used to select households). Several WMH surveys (Belgium, Germany, Italy) used municipal resident registries to select respondents without listing households. The Japanese sample is the only totally unclustered sample, with households randomly selected in each of the four sample areas and one random respondent selected in each sample household. In total, 10 of the 15 surveys are based on nationally representative (NR) household samples, while two others are based on NR household samples in urbanized areas (Colombia, Mexico).
