Epidemiology of mental disorders

Te Rau Hinengaro: The New Zealand Mental Health Survey is this country's first (and only) national survey of mental disorders.

Face-to-face interviews were conducted on just under 13,000 individuals, with oversampling of Māori and Pacific peoples. It is one of the largest in-depth surveys of the epidemiology of mental disorders internationally.

First results were published in 2006. Te Rau Hinengaro is part of the World Mental Health (WMH) Surveys initiative, a consortium of psychiatric epidemiology surveys conducted in around 30 countries under the auspices of the World Health Organisation and Harvard Medical School.

The WMH Surveys Initiative provides the first information on mental disorder epidemiology for many countries, using state-of-the art psychiatric epidemiology methods and analytical techniques.

Professor Kate Scott has been funded by the Health Research Council for two projects (2009–2011 and 2011–2014) involving secondary analyses of the New Zealand and cross-national WMH datasets, respectively. Additional funding has been received from the James Hume Bequest for ongoing analyses of the cross-national data.

The WMH Surveys Initiative has led to the publication of several hundred journal articles and a series of books published by Cambridge University Press.
