skilled surgeons or even of money but rather to a shortage of organs available for transplantation. In part, the shortfall reflects an increase in the number of patients who might benefit from a transplant, due to better screening and improved immunosuppressant drugs (Caplan, 1984). The major reason for the shortage, however, is simply a lack of sufficient donors.The ramifications of this shortage are tragic. In 1980 alone, approximately 14,000 people died because they did not receive needed heart transplants (Evans, Manninen, Gersh, Hart, & Rodin, 1984). The American Council on Transplantation estimated that there were 13,000 patients needing a kidney transplant on any given day in 1988 (Clark, Robinson, & Wickelgren, 1988). The need for other organs such as pancreas, liver, bone marrow, corneas, lungs, and skin, is also high, with around 10,000 people waiting for organs to become available (U.S. Department of Health and Human Services, 1988). Potential transplant recipients may wait for years, if they survive, before a suitable donor organ can be found. Unfortunately, the longer the delay, the greater the probability of medical complications.These shortages do not appear to be due to lack of potential organs that are suitable for donation. One estimate concluded that only about 3,000 out of an estimated 23,000 organs that could be donated were in fact donated (Warmbrodt & Koch, 1985). Even a modest increase in the rate of donation would go a long way toward reducing this shortage because a single donor can provide over a dozen viable organs and tissues for transplantation. The central question is: Why are there so few decisions to donate?One common answer in the medical literature is that lack of knowledge about the need for donors is responsible for the shortage. Accordingly, considerable effort has been made in recent years to increase awareness, even sympathy, regarding the plight of potential organ recipients (e.g.,
