Endure bibliography

Last verified: 2026-09-13. 407 entries checked, 30 corrected, 2 set aside from the public page.

This is the literature behind Endure: the sources its check-in conditions, its specialty packs, its Recovery content, and its measurement rules are built from. Every entry was pulled from the evidence reviews the team keeps for each specialty and from the citation cards inside the app. Nothing here is invented: where a review recorded only an author, year, and journal, this page cites exactly that much rather than filling in what was never recorded, and a few entries carry a note saying so. The page grows as packs grow.

405 sources on the public page: 350 peer-reviewed studies and reviews, 55 gray-literature and institutional sources. 2 entries found and set aside sit in the final section.

Peer-reviewed literature is grouped by broad area, then alphabetized by first author within each group. A paper reused as evidence for more than one specialty is listed once, in the section that best fits its primary subject. Gray literature (specialty-society statements, trade press, survey reports, and other public sources that are not peer-reviewed research) is listed separately, alphabetized by organization or outlet.

Sources named only in passing in the app's copy, with no author, year, or journal recorded anywhere, are not listed: an allusion is not a citation, and this page does not invent one to fill the gap.

Verification, 2026-09-13: every entry with a PMID was checked against PubMed and every entry with a DOI against Crossref (authors, year, journal, title); entries with neither were searched for and given an identifier where the paper could be found. Where a journal prints an article in a later volume than its online release, the entry keeps the year the app cites and notes the print year. Links to public web sources were tested the same day. The one entry that could not be verified is marked [unverified]. Entries an evidence review found and rejected are kept in the source file and are not shown on this page.

  • Businelle et al. (2024). J Med Internet Res. doi:10.2196/50275. 411-person factorial RCT comparing 15 versus 25 items per daily prompt: no effect on compliance below roughly 25 required items; completion 83.8%.

  • Eisele et al. (2022). Assessment. doi:10.1177/1073191120957102. The only randomized experiment on survey length in daily experience-sampling: 60 items per prompt versus 30 raised burden, lowered compliance (about 89% versus 84%), and increased careless responding; compliance also decayed over days in every study arm.

  • Williams et al. (2021). J Med Internet Res. doi:10.2196/17023. Meta-analysis of 168 mobile experience-sampling studies: prompts with more than 26 items ran 63% compliance versus 79 to 84% at 26 items or fewer; the median items per prompt across studies was 8 to 10.
