Finding a validated instrument on your potential topic is an important step for your Scholarly Project. Some instruments are published and only available for purchase. Others may be used for educational purposes at no charge (although you should still get permission from the author of the instrument to use it for your research). Below are some starting points for finding instruments that are available either as a stand alone option (APA PsycTests) or appended to a journal article in CINAHL, MEDLINE or APA PsycInfo. See below for how best to maximize your success when searching each database.
