Childhood Asthma Prevention Study (CAPS)

Model effectiveness research report last updated: 2012

In brief

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.

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.

1When an individual manuscript reports findings from multiple studies, HomVEE reviews each study as a distinct manuscript. In these rare instances, HomVEE counts that manuscript multiple times in this table, once for each study identified, screened, and reviewed by HomVEE.

2Additional sources have findings or details that perfectly overlap with another manuscript and are not rated.

For more information, see the research database. For more information on the criteria used to rate research, please see details of HomVEE’s methods and standards.

The section above focuses on findings from the full sample in a study. Subgroups that have been replicated in distinct samples also have findings reported above. HomVEE does not report the findings of non-replicated subgroups. Beginning with research reviewed in 2021, however, HomVEE, lists those subgroups on the details page of each manuscript that had at least one finding that rated moderate or high.

Criteria established by the U.S. Department of Health and Human Services

Information based on comprehensive review of all high- and moderate-rated manuscripts
CriterionCriterion descriptionCriterion met?
1High- or moderate-quality impact study?Yes
2Across high- or moderate-quality studies, favorable impacts in at least two outcome domains within one sample OR the same domain for at least two non-overlapping samples?No
3Favorable impacts on full sample?Yes
4Any favorable impacts on outcome measures sustained at least 12 months after model enrollment?
Reported for all research but only required for RCTs.		Yes
5One or more favorable, statistically significant impact reported in a peer-reviewed journal?
Reported for all research but only required for RCTs.		Yes

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.
