Childhood Asthma Prevention Study (CAPS)
Last updated: 2012
Evidence of model effectiveness
This model does not meet the criteria established by the Department of Health and Human Services (HHS) for an “evidence-based early childhood home visiting service delivery model” for the general population or for tribal populations because the findings from high- or moderate-rated effectiveness studies of the model do not meet all required criteria.
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.
Extent of evidence
Criteria established by the U.S. Department of Health and Human Services
Notes: If the model does not meet criterion 3 but meets criteria 1 and 2 based on findings from subgroups, the impacts must be replicated in the same domain in two or more studies using non-overlapping analytic study samples. HomVEE assesses and reports criteria 4 and 5 for all models that have well-designed research, but meeting those two criteria is only required of models for which all findings are from randomized controlled trials. Please read the HHS criteria for evidence-based models for more information.
