The easiest and most appropriate way to search for scales, instruments, tools, questionnaires, or inventories and their psychometric properties [that is validity and reliability] is to go to the library, better still, visit project the archive or store to look for previous research works conducted on the said topic or the variable of interest.
You can also search through the internet or websites that have them available although some of these scales may not be free on demand which would mean that you will have to pay for them or contact their developers and this may limit your interest in the said topic. What the heck is that rubbish?
It is for this very reason that I have enlisted a summary of variables that many of them have scales confirmed to be free online. You are expected to search on your own, the best scales with the items that measure your variables with adequate validity and reliability.
