Attitudes Toward Euthanasia for Patients Who Suffer From Physical or Mental Illness

This study examined whether attitudes toward euthanasia vary with type of illness and with the source of the desire to end the patient's life. The study used a 3 (illness type: cancer, schizophrenia, depression) × 2 (euthanasia type: patient-initiated, family-initiated) between-groups experimental design. An online questionnaire was administered to 324 employees and students from a Australian public university following random assignment of participants to one of the six vignette-based conditions. Attitudes toward euthanasia were more positive for patients with a physical illness than a mental illness. For a patient with cancer or depression, but not schizophrenia, approval was greater for patient-, than, family-, initiated euthanasia. Relationships between illness type and attitudes were mediated by perceptions of patient autonomy and illness controllability. Findings have implications for debate, practices, and legislation regarding euthanasia.
