Having spent a considerable amount of time thinking about the uses of large-scale descriptive psychiatric epidemiological needs assessment surveys in our capacity as co-directors of the World Health Organization's World Mental Health Survey Initiative, we agree with many of the conclusions of Henderson and Andrews. Most importantly, we agree:

∘ that the time has come to expand the focus to study causes.
