The purpose of this study is to develop and test a model for end-of-life decision making, with an emphasis on determining what role the patient would like to play in the process. Patients with terminal illnesses were interviewed regularly over a period of up to two years in an effort to gain insight into their control preferences.
The long-term goal is to enhance communication among the patient, family and healthcare provider.

We modified the Decision Control Preference Scale of Degner and Sloan (1992) to measure the amount of control over end-of-life decisions that patients prefer to retain or place with the physician and/or family. Decision control preferences will be examined every three months for two years in 101 patients with terminal illnesses who have a prognosis of approximately two years of life. Patients will be followed from early in the diagnostic period for two years or until death.
The illnesses selected are characterized by a steady progression towards death (amyotrophic lateral sclerosis, (ALS) and Lung cancer) and an unpredictable course and sudden death (heart failure). This longitudinal, multi-method study is based on an eclectic conceptual approach, and The Patient Decision Making Framework, that includes the findings of Degner and others.
All subjects will be evaluated with quantitative measures and a subset of five subjects in each disease group will also be interviewed with qualitative measures. Data will be analyzed to determine the influence of selected demographic, psychosocial, and health characteristics on decision control preferences and the decision control preferences of patients over time.
