Outcome Description of Measure Data Collection Method Properties of the Outcome Measure Outcome Type
Cat dander Percentage of homes in which the presence of cat dander was higher than the standard cut-off levels. House dust collection Not applicable Primary
Cockroach allergen Percentage of homes in which the presence of cockroach allergen was higher than the standard cut-off levels. House dust collection Not applicable Primary

Family Asthma Management System Scale--asthma knowledge and collaborative relationship subscales The scale was adapted to assesses the caregiver's illness management practices with a wheezing infant. The authors used the asthma knowledge and collaborative relationship with medical care provider subscales. Items were coded on a 9-point scale. Parent/caregiver report Interrater reliability ranged from 0.82-0.96 for the asthma knowledge subscale and from 0.79-0.96 for the collaborative relationship subscale Primary
HOME score The Home Observation for Measurement of the Environment inventory (0-3 years) assesses parent-child interactions. Observational assessment Interrater reliability was 93.2% Primary
