Forced swim test with chronic unpredictable stress
From 2021 to 2025, 570 animal research papers mentioned chronic unpredictable stress and the forced swim test in their title or abstract.
That is 2.6 times the 223 papers of 2011 to 2015. Between the same two periods, the papers that mention chronic unpredictable stress and any of the 90 tests we count grew more slowly, to 2.1 times as many.

Which species the papers used
Each bar is a share of the 570 papers from 2021 to 2025. A paper can use more than one species, so the shares can add to more than 100%.
Species
“Other animals” counts papers that use none of the species this chart names.
Tests mentioned alongside the forced swim test
Each bar is one test, with how many of the 570 papers also mention it, and what share that is. Of these papers, 73 (13%) mention no other test.

Which papers count
A paper counts here when it is animal research and its title or abstract mentions chronic unpredictable stress and the forced swim test.
A paper that mentions either only in its methods is missed, so the count runs low. The search terms are in the list of models and techniques and the test list. The full method, with each source and its terms of use, is on our main page, Behavioral tests in published research.
More pairings
Every pairing of an animal model and a test with 30 or more papers from 2021 to 2025 has a page like this one.
