A questionnaire survey of a random sample of 7,136 participants, aged 20-79 years, was conducted in 7 Japanese municipalities where standardized mortality ratios from suicide were compared with a Japanese standard. Data from 5,547 subjects were analysed. The Self-Rating Depression Scale score was significantly higher in the high standardized mortality ratio group in women but no significant difference among the 3 standardized mortality ratio groups was observed in men. Most of the psychosocial factors or knowledge of & attitudes toward suicide & depression were not adversely associated with standardized mortality ratio groups. (28 refs.)
