The News story 'China tackles surge in mental illness' ( Nature 468, 145; 2010) incorrectly implied that Wanjun Guo leads a 20-million-yuan project to survey mental disorders in the 'post Wenchuan earthquake' region. Guo is merely a participant in the project, which is itself only part of a 20-million-yuan effort to study the psychological impact of the quake and identify potential interventions.
