This video will show you how to search multiple library databases at once to find evidence-based programs on your topic.
Public health information tends to be multi-disciplinary, meaning you'll often need to search several databases geared toward different disciplines. For example, if you are designing a program to educate families about the signs and symptoms of depression, you may end up searching PubMed or Medline (biomedical), PsycINFO (psychology), ERIC (education), and Family Studies Abstracts (sociology).
Note that the website looks different in this video, but the searching process is the same.
