This study examined public opinions on suicide in 4 situations (incurable disease, bankruptcy, family dishonor, & being tired of living), using data from 4 national surveys conducted in 1977, 1978, 1982, & 1983. Results indicate that suicide in the case of incurable disease was most likely to be approved & that respondents with attributes of higher education, lower religiosity, & higher commitment to freedom of expression were more likely to consider suicide as acceptable.
