1The World Bank (2012) Data. Accessed May 12, 2012 at: Some of the WMH countries have moved into new income categories since the surveys were conducted. The income groupings above reflect the status of each country at the time of data collection. The current income category of each country is available at the preceding URL.

2NSMH (The Colombian National Study of Mental Health); IMHS (Iraq Mental Health Survey); NSMHW (The Nigerian Survey of Mental Health and Wellbeing); B-WMH (The Beijing World Mental Health Survey); S-WMH (The Shanghai World Mental Health Survey); EMSMP (La Encuesta Mundial de Salud Mental en el Peru); (Bulgaria National Survey of Health and Stress); MMHHS (Medellín Mental Health Household Study); LEBANON (Lebanese Evaluation of the Burden of Ailments and Needs of the Nation); M-NCS (The Mexico National Comorbidity Survey); RMHS (Romania Mental Health Survey); NSMHWB (National Survey of Mental Health and Wellbeing); ESEMeD (The European Study Of The Epidemiology Of Mental Disorders); NZMHS (New Zealand Mental Health Survey); NISHS (Northern Ireland Study of Health and Stress); EZOP (Epidemiology of Mental Disorders and Access to Care Survey); NMHS (Portugal National Mental Health Survey); PEGASUS-Murcia (Psychiatric Enquiry to General Population in Southeast Spain-Murcia); NCS-R (The US National Comorbidity Survey Replication).

3Most WMH surveys are based on stratified multistage clustered area probability household samples in which samples of areas equivalent to counties or municipalities in the US 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) and the Netherlands (where postal registries were used to select households). Several WMH surveys (Belgium, Italy) used municipal resident registries to select respondents without listing households. 16 of the 23 surveys are based on nationally representative household samples.

4The response rate is calculated as the ratio of the number of households in which an interview was completed to the number of households originally sampled, excluding from the denominator households known not to be eligible either because of being vacant at the time of initial contact or because the residents were unable to speak the designated languages of the survey. The weighted average response rate is 71.4%.

5For the purposes of cross-national comparisons we limit the sample to those 18+.

6Colombia moved from the "lower and lower-middle income" to the "upper-middle income" category between 2003 (when the Colombian National Study of Mental Health was conducted) and 2010 (when the Medellin Mental Health Household Study was conducted), hence Colombia's appearance in both income categories.

2Based on a pooled within-survey logistic regression model adjusting for between-survey variation in the association of age-sex with student status.
3The AUCs were generated from logistic models in which dummy variables for being an attriter or other nonstudent were included as predictors of the mental disorder in the row heading or, in the case of Part VI, number of disorders estimated in an order logistic framework, controlling age-sex and survey.

1Pre-matriculation onset disorders were defined as those with onsets at ages 0-17.

2Post-matriculation onset disorders were defined as those with onsets at ages 18+.

3Respondents were limited to those in the Part II sample who were 18-22 years old at the time of interview and had not graduated from college.

4Based on a pooled within-survey logistic regression equation adjusting for between-survey variation in the association of age-sex with student status

5There were no post-matriculation onsets of these disorders by definition, as the CIDI required onsets before age 8 (ADHD) or 18 (Conduct Disorder, Oppositional Defiant Disorder).

6Prevalence of post-matriculation onsets was estimated in the subsample of respondents who did not have a pre-matriculation history of the disorder. As a result, the sample size for each calculation varies across disorders from a low of 653 among male students who had no pre-matriculation history of specific phobias to a high of 742 among male students who had no pre-matriculation history of drug dependence, with a median sample size of 731. The sample size for having no pre-matriculation history of any disorder is 544 among male students.

7Prevalence of post-matriculation onsets was estimated in the subsample of respondents who did not have a pre-matriculation history of the disorder. As a result, the sample size for each calculation varies across disorders from a low of 239 among male attriters who had no pre-matriculation history of specific phobias to a high of 267 among male attriters who had no pre-matriculation history of panic disorder, with a median sample size of 256. The sample size for having no pre-matriculation history of any disorder is 170 among male attriters.
