A 2012 paper on using forced swim tests to measure the effects of anti-depressants suggests variable times for the duration of the tests, although 15 minutes seems common (Slattery & Cryan: Using the rat forced swim test to assess anti-depressant like activity in rodents). Ten years on, is the model still considered reliable, is there an industry standard for duration that is commonly used (or is this dependent on other factors), and are there any recent references for refinements and best practice for conducting FSTs?
Professor Clare Stanford has vast experience on the validity of this model. See this recording of an interview with her and other researchers on the subject of Animal research, antidepressants and the forced swim test. See also:
