Noncompliance with medication is a prevalent problem for pediatric asthma patients, particularly for pre-adolescents and adolescents. Families reportedly struggle with the transition of expecting adolescents to assume more independence and responsibility in asthma management. Parent-child collaborative management of pediatric chronic illness regimens has been related to better adherence to medical regimens and improved health outcome. This study has four aims. The first aim is to investigate the effectiveness of a low-intensity, behavioral intervention aimed at promoting parental involvement in children’s asthma management, particularly in improving medication adherence. The second aim is to examine how the role of parental involvement changes across time and participation in a 5-month study. A third aim is to determine whether parent-adolescent conflict is changed by the intervention. The fourth aim is to evaluate whether participation in the treatment program is associated with improved health status (e.g., improved pulmonary function test results).
