Abstract

Background: Emotional stress triggers and exacerbates asthma in children. Reducing anxiety in adults by relaxation-breathing techniques has been shown in clinical trials to produce good asthma outcomes. However, more evidence is needed on using this intervention with asthmatic children.

Objective: To evaluate the effectiveness of combined self-management and relaxation-breathing training for children with moderate-to-severe asthma compared to self-management-only training.

Design: Two-group experimental design.

Setting and participants: Pediatric outpatient clinic of a medical center in central Taiwan. Participants were 48 children, ages 6-14 years, with moderate-to-severe asthma and their parents.

Methods: Participants were randomly assigned to an experimental or comparison group and matched by gender, age, and asthma severity. Both groups participated in an asthma self-management program. Children in the experimental group were also given 30 min of training in a relaxation-breathing technique and a CD for home practice. Data on anxiety levels, self-perceived health status, asthma signs/symptoms, peak expiratory flow rate, and medication use were collected at baseline and at the end of the 12-week intervention. Effects of group, time, and group-time interaction were analyzed using the Mixed Model in SPSS (12.0).

Results: Anxiety (especially state anxiety) was significantly lower for children in the experimental group than in the comparison group. Differences in the other four physiological variables were also noted between pre- and post-intervention, but these changes did not differ significantly between groups.

Conclusions: A combination of self-management and relaxation-breathing training can reduce anxiety, thus improving asthmatic children's health. These results can serve as an evidence base for psychological nursing practice with asthmatic children.
