Improving the psychological status of children with asthma: a randomized controlled trial.

Children with asthma are at special risk for problems in psychological functioning, as are children with other chronic illnesses. We conducted a controlled trial of a combined education and stress management program among children ages 6 to 14 years with asthma. Eighty-one children were randomly assigned to an intervention or a control group; 56 children completed data collection, 29 intervention and 27 control. Psychological status was assessed by the Child Behavior Checklist (CBCL) before and after the intervention, as were children's knowledge of asthma, stress (as measured by children's life events), and functional status (as indicated by such activities as school attendance, time playing with friends, and daily chore performance). Children in the intervention group had a significant improvement in the total Behavior Problems score (p less than .04) and Internalizing scale (p less than .01) on the CBCL and a significant increase in daily chores (p less than .04) compared with the control group. Before intervention, the two groups had statistically significant positive relationships between negative life events and behavior problems scores. After intervention, children in the control group still demonstrated a significant relationship between negative life events and total and Internalizing Behavior Problem scores, although participation in the intervention group negated that relationship. Children in the intervention group whose knowledge of asthma increased were more likely to report an increase in daily chores (p less than .02). We conclude that the intervention had a beneficial effect on psychological status and on children's daily activities. The effect may have occurred in part by decreasing the likelihood that perceived stress from negative life events led to poorer adjustment.
