What is the correct punctuation when doing both a test name acronym AND an parenthetical format, in-text citation? In the Method section, I am including a list of each test used, along with a brief description. Since it's the first of multiple times each test is mentioned, I need to include the acronym and the citation. Impact of Events Scale-Revised (IES-R)(Weiss and Marmar, 1996). Secondary measure of psychological reactions to stress. My professor wasn't sure either and offered 4 different versions of parentheses, colons, semi-colons, and periods!
