An educational training program for children with asthma, aged between 8 and 13 years, was evaluated in an 18-month randomized, controlled experiment, including three follow-up evaluations. The objective of the program is to improve coping with asthma in daily life. The program, ten 1-hour sessions, is a combination of self-management training and cognitive behaviour therapy in a group, using games and learning materials specifically designed for this age group. From 195 asthmatic children, 112 with inadequate self-management abilities were selected; these children were randomly divided into an experimental group and two control groups. The results indicated highly significant differences in favor of the experimental group on the psychological and medical variables. There were no drop-outs during the program. The conclusion is that this multi-faceted program is an effective method of teaching children how to cope with their asthma and helping them to achieve a less anxious and more realistic attitude towards their illness.
