A non-experimental, exploratory field study was designed to investigate the impact of a diagnosis of nonresectable lung cancer on eight subjects' relationships with others and plans for the future. Participant observation, systematic verbal and behavioral communications between subjects and investigator were the primary methods of inquiry. Such data as information concerning diagnosis and prognosis transmitted by physician, and subject's behavior in relation to family and significant others were collected. The results of these data suggest that different communication strategies are needed to help the individual and his family cope with the situation. Return visits may be an appropriate time for a systematic approach to problem-solving by a trained health care professional. (KS)
