Once you've used the thesaurus to locate appropriate terminology, narrow your results by searching for Subject headings, instead of "All fields" searching.
An "All fields" search for the term "behavior modification" will result in a list of more than 25,000 peer reviewed articles, whereas a "Subject heading" search for "behavior modification" will narrow your results to less than 10,000 peer reviewed articles.
LIMIT BY LANGUAGE, POPULATION, or AGE
PsycINFO makes it easy to limit by language, the age of the population being studied, the type of subject being studied (animal/human) and other categories. Scroll toward the bottom of the advanced search screen to see these options:
PUTTING IT ALL TOGETHER
Combine all of the techniques described on this page and you will be able to construct very precise searches that should give you relevant results.
For example, an "All fields" search for depression and behavior modification results in a list of nearly 5,000 peer reviewed articles.
Using the thesaurus to find subject headings, you can do another search for Major Depression (Subject heading) and Behavior Modification (Subject heading), and include a limit to English language articles, our results are less than 40 peer reviewed articles. A much easier list to scan!
PsycINFO - advanced searching
PsycINFO is the premier database for doing research in the field of Psychology. It allows users to search through thousands of psychology journals going back as far as the early 1800's.
USE BOOLEAN OPERATORS
Connecting words with Boolean operator "OR" will broaden your search, connecting words with the "AND" will narrow your search.
