Videotape educational program for people with asthma.

A videotape educational program was produced for use in adults with asthma. The program provided an overview of lung function, the physiologic abnormalities and treatment of asthma, and the approach to common problems encountered by the patients. Its benefits were examined in a randomized controlled study. The efficacy of the program in 62 patients whose mean duration of illness was 17 years was assessed by comparing the level of knowledge of the experimental group immediately after viewing the tape with that of the controls, who had not seen it; the experimental group scored significantly higher than the control group. Retention of knowledge attributed to the program was assessed after a mean interval of 16 months. The knowledge test score of the experimental group was found to have decreased to the level of the control group. The main areas in which the experimental group lost knowledge were self-care and drug therapy for asthma. The medical status of the two groups did not change appreciably over the period of the study.
