| Research Abstract |
We prepared a survey questionnaire, translating and back translating the questions, developing a software which ran the CAPI (Computer Assisted Personal Interview), and then trained interviewers and conducted a production survey in 2001-2002. A letter was sent to a random sample (n=1607) from community residents in Okayama city and 27 interviewers completed interviews for 925 subjects (response rate, 66%, after excluding non-eligible subjects). Major depression, specific phobia, alcohol abuse were relatively common in this city. The lifetime prevalence of major depression was 7-8%, and the 12-month prevalence was 2.5-2.6%. We reported a preliminary finding at an international meeting in France, July 3-10, 2003 to obtain a further advice on the analysis. In 2003, a sample was drawn from the respondents who experienced mental disorders and did not, and we conducted a follow-up survey including blood sampling and psychophysiological examinations. Several genetic markers were measured. These surveys were reviewed and approved by the research ethics committees of the Okayama University Graduate School of Medicine & Dentistry. We analyzed associations among mental disorders, suicide behaviors, social functioning, QOL, occupational variables, genetic factors.
