Asthma training programs for parents and children have been developed to increase both the self-management skills of asthmatic children and compliance with medical regimes. In order to evaluate two training programs for asthmatic children aged 7-14, 81 patients were randomly assigned to three groups. Group 1 consisted of 27 patients and their parents who participated in a five-day standardized family-oriented clinical asthma training program. They had monthly follow-up meetings with the training team for a period of six months. Group 2 (n = 29) had the same clinical training without follow-up interventions; a control group (n = 25) received regular medical treatment according to the international guidelines at the asthma clinics without a training program and served as control group. Questionnaires regarding self-management aspects, coping and anxiety were filled out by patients, parents, family doctors and the training team prior to as well as twelve months after the training. The results indicate that Training group 1 benefitted most with respect to active asthma self-management, Training group 2 to some degree while the control group showed no significant effects. The differences after one year between the three groups regarding physical parameters such as lung-function and days missed in school did not reach the level of significance. Our results indicate that the long-term efficacy of self management courses for asthmatic children is enhanced by regular follow-up training sessions.
