“…In their review of ethical issues in conducting research with palliative care populations, Kristjanson, Hanson, and Balneaves (1994) found that almost half of the projects included participants who were in advanced stages of illness. Dying people suffer diminished physical and, often, impaired cognitive and psychological states (Kovacs, 1998;Kristjanson, Hanson, & Balneaves, 1994); therefore, participant attrition is an expected occurrence (Dean & McClement, 2002;Dush & Cassileth, 1985, Kinzbrunner, 1995. As a result, researchers are often torn between securing an adequate study population and enrolling less than competent participants (Kristjanson et al, 1994).…”
