Self-administration in psychological stress research

From 2021 to 2025, 36 animal research papers on psychological stress mentioned self-administration in their title or abstract.

That is 47% fewer than the 68 papers of 2011 to 2015. Between the same two periods, the papers on psychological stress that mention any of the 90 tests we count fell 10%. The 2021 to 2025 count may run low because of a dip in PubMed's indexing, explained under the year chart.

Papers on psychological stress that mention self-administration fell from 10 in 2021 to 2 in 2023, then rose to 12 in 2025. Part of this dip may come from PubMed's indexing rather than from fewer studies. Where PubMed has indexed a paper, we take its disease models from that indexing. Otherwise PubTator 3, NCBI's text-mining service, has to find the disease in the title or abstract, or the paper is not counted here. Papers that PubMed indexed under the subject heading Animals also fell and rose, from 200,221 in 2021 to 156,447 in 2023 and 235,479 in 2025.

Which species the papers used

Each bar is a share of the 36 papers from 2021 to 2025. A paper can use more than one species, so the shares can add to more than 100%.

“Other animals” counts papers that use none of the species this chart names.

Tests mentioned alongside self-administration

Each bar is one test, with how many of the 36 papers also mention it, and what share that is. Of these papers, 19 (53%) mention no other test.

Which papers count

A paper counts here when it is animal research, mentions self-administration in its title or abstract, and studies psychological stress.

We tell whether a paper studies psychological stress from its MeSH terms, the subject headings the National Library of Medicine adds when it indexes a paper. For a paper without MeSH terms, PubTator 3, NCBI's text-mining service, has to find the disease in the title or abstract. A paper can count under more than one disease model. A paper that mentions the test only in its methods is missed, so the count runs low.

The page on psychological stress research names the subject headings we count as psychological stress. Download the test list for the search terms we used for self-administration, or the paper list for the PubMed ID of every paper behind these counts. Our main page, Behavioral tests in published research, has the full method and each source's terms of use.

More tests and disease models

Every pairing of a disease model and a test with 30 or more papers from 2021 to 2025 has a page like this one.

Papers on other disease models that mention self-administration

The page on self-administration counts all the papers that mention it, whatever they study. The page on psychological stress research ranks the tests by their papers on psychological stress.
