Incorporating family therapy into asthma group intervention: a randomized waitlist-controlled trial. Family therapy in the treatment of severe childhood asthma.
Asthma psychoeducational programs have been found to be effective in terms of symptom-related outcome. They are mostly illness-focused, and pay minimal attention to systemic/familial factors. This study evaluated a novel asthma psychoeducation program that adopted a parallel group design and incorporated family therapy. A randomized waitlist-controlled crossover clinical trial design was adopted. Children with stable asthma and their parents were recruited from a pediatric chest clinic. Outcome measures included, for the patients: exhaled nitric oxide (eNO), spirometry, and adjustment to asthma; and for the parents: perceived efficacy in asthma management, Hospital Anxiety and Depression Scale anxiety subscale, Body Mind Spirit Well-being Inventory emotion subscale, and Short Form 12 health-related quality of life scale. Forty-six patients participated in the study. Attrition rates were 13.0% and 26.0% for the active and control groups, respectively. Repeated-measures ANOVA revealed a significant decrease in airway inflammation, as indicated by eNO levels, and an increase in patient's adjustment to asthma and parents' perceived efficacy in asthma management. Serial trend analysis revealed that most psychosocial measures continued to progress steadily after intervention. Significant improvements in both symptom-related measures and mental health and relationship measures were observed. The findings supported the value of incorporating family therapy into asthma psychoeducation programs. Eighteen children with severe, chronic bronchial asthma were randomly divided into two groups. The families in one group received family therapy while the others served as a control group in a controlled family therapy study. Later the control families were also offered therapy in a before-after therapy design. All children were followed for 3 1/2 yr. Asthma symptoms, functional impairment and the use of drug (from diaries) were rated in ten different ways during eight months before and eight months after the family therapy. Improvement in the clinically most important variable, i.e. general pediatric assessment, was greater in the children in the family therapy group compared to the control group (p less than 0.05) Twelve children who received family therapy showed significant improvement after treatment concerning general pediatric assessment (p less than 0.01), clinical grading (p less than 0.05), peak expiratory flow (p less than 0.05), days with functional impairment/yr (p less than 0.05), no. of doses of inhaled Beta-2-agonists/month (p less than 0.01) and nights when Beta-2-agonists were inhaled (p less than 0.05). The children who only received conventional medical treatment showed no significant change in asthma symptoms. We draw the conclusion that family therapy may represent a valuable therapeutic tool in the management of severe asthma.
There is some indication that family therapy may be a useful adjunct to medication for children with asthma. This conclusion is limited by small study sizes and lack of standardisation in the choice of outcome measures.
