To cite an ACHS classroom module use the following APA format:
Author, A. A. (Publication Year) Title of lecture [Online lecture]. Retrieved from http://www.xxx
The author of the course is either Petersen, D. (if it is a clinical correlate or monograph within the course) or ACHS (if it is anything other than a clinical correlate or monograph).
If you were to cite content within the module, that is not produced by ACHS, how it is formatted depends on what type of source it is. For example, if you were to cite a website, you would use the following citation format:
Author, A. A. (year, month, year of publication). Title of webpage. Retrieved from http://www.xxx
