research on homeless youth
There are a few places you might go to find articles (more current information) on homeless youth. If you go to the Find Articles page, one of the best databases to start your research is called ProQuest Central.
The most powerful way to search in the ProQuest databases is to go to the Advanced Search page (there is a link to it above the right side of the search box when you first get into ProQuest). This gives you multiple search lines, so you can enter different concepts on different rows to narrow or focus your search. The rows that have more than one entry box use a Boolean "OR" between the concepts in the different boxes (so you could put child in one box and youth in another to get either words in your search results).
Doing a search for "homeless youth" (using the quotes) also finds many articles, and using the quotes around the phrase means you want both of these words and together in that order, which will limit some erroneous hits from your results. To get the "cream of the crop" articles, you would want to click in the checkbox immediately in front of "Peer reviewed" and you may also want to put a checkmark next to Full text as well (there are a lot of results, so limiting like this leaves you with a smaller but still large number - 750 results for the phrase search and limiting to full text and peer reviewed). If you want to narrow your results further, the top of the results screen has a search box where you can enter more terms and click on the orange "magnifying glass" button to re-search.
If you are looking for something about development (psychological, mental, social) of youth, I would also suggest going into the PsycARTICLES & PsycINFO database. If you do an advanced search in this database, you can just search for the term "Homeless" and choose age limits in the "Age group" area that is a little over halfway down the page. You can choose multiple specific ages, depending on the ages of the children you are interested in.
Hope this helps!
