Please keep in mind that many psychology databases use "controlled vocabulary." It is very useful to note and use subject terms that are attached to articles you find useful for your research. By using different combinations of terms (ie as search strategy) you will be able to find more relevant articles.
For example if I typed in the search "homeless students" and "school pschology or school pschologist" the results would include articles that focused on "academic acheivement" "educational programs" "school based interventions" "high schools" and so forth. I could then consider combining "school psychologist" "school based interventions" in a new search. Often you will need to combine differen terms together in new searches to find relevant resources. Refer to the Ask a Librarian for help box if you run into problems.
