Yes, we can do this in PsycInfo database. Type your keyword, e.g., motivation and in the second row of the drop-down menu type appended (make sure you change the name in the drop-down menu field to TM Tests & Measures. See the example below
You can view the tests when you open the full text of the article. Please note that this feature is available only for articles published since 2004 and some articles will have only partial tests appended.
