Summary Evidence Table – Effectiveness Review [PDF -216 kB]
Contains evidence from reviews of home-based multi-trigger, multicomponent environmental interventions for adults and for children and adolescents
The number of studies and publications do not always correspond (e.g., a publication may include several studies or one study may be explained in several publications).

The following outlines the search strategy for home-based multi-trigger, multicomponent environmental interventions for adults and for children and adolescents.
With the assistance of a CDC librarian, the team searched for published studies in the following databases: MEDLINE, Cochrane Library, CINAHL, PsychINFO, Web of Science, EMBASE, ERIC, and Sociological Abstracts. The team also searched bibliographic reference lists and accepted suggestions of studies from members of the team.
The team considered studies for inclusion if they:
- Were primary research published in a journal or a technical or government report
- Were published in English
- Met minimum research quality criteria for study design and execution—specifically, using designs with before-and-after comparisons in the intervention group at least or comparisons across two groups receiving different levels of intervention
- Were community-based
- Evaluated one of nine identified asthma interventions
- Addressed secondary or tertiary prevention
Studies for home-based environmental interventions were considered if they also:
- Included at least one home visit
- Were multicomponent
- Were multi-trigger
- Evaluated one or more outcomes of interest
The team searched for and accepted for possible inclusion studies published from 1966 to February 2008.
