Model Description

The Childhood Asthma Prevention Study (CAPS) was designed to reduce children’s wheezing-related morbidity by reducing household allergens and increasing caregiver illness-management skills. CAPS participants were low-income families living in the Denver metropolitan area with children between 9 and 24 months old who had experienced at least three wheezing episodes. Nurses trained as home visitors addressed allergen and tobacco smoke reduction, as well as psychosocial factors of illness management, including parental knowledge, parent-child relationships, and caregiver mental health. Home visitors guided and supported caregivers’ efforts to achieve health-promotion goals through education, problem solving, and referrals for additional services. CAPS consisted of 18 home visits delivered over the course of a year. For more information, please read the Model Overview.
