Filters/HEDGES

Filters are standardized or pre-formulated searches for specific concepts, methodologies, populations or geographic regions. They are also referred to as hedges or clinical queries. Filters will use a combination of keywords and controlled vocabulary and are database and platform specific. For example, a search filter designed to be used in PsycINFO on the EBSCO platform will not work the same way in PsycINFO on a different platform (such as OVID or APA PsycNet).

Note: If you use a filter in your search, remember to cite it.
