This study examined how attitudes toward voluntary euthanasia vary across categories of 4 situational factors: type of assistance, type of assistant, type of illness & age of patient. A random sample of 514 adult residents of Ohio indicated that more active assistance is favoured over less active, & that voluntary euthanasia for cancer patients receives more support than does voluntary euthanasia for Alzheimer’s patients. Findings are discussed at micro- & macro-levels of analysis. (37 refs.)
