Abstract
This article reviews replications and extensions of Living with Asthma, a self-man agement system developed and tested at the National Asthma Center in Denver be tween 1977 and 1980. Research on the system since the latter date has been con ducted within the conceptual framework provided by the social or cognitive learning model. This approach has switched experimenter effort away from developing and evaluating the acquisition of self-management skills toward assessing their performance by patients. Efforts to insure these skills are used effectively by patients to control their asthma, focusing particularly on the assessment of performance variables, are described.
