This pre-registered study (AsPrediced#139837) explored the role of expectations and tailored health feedback on the OLP effect using an automated online procedure.

Participants were informed the pills were inert but may enhance wellbeing. Wellbeing was assessed at baseline, day-5 and day-10. Feedback was delivered on day-5 and day-10 via interactive graphs and descriptive statistics. OLP-treatment significantly improved wellbeing (negative emotions and sleep quality), while feedback did not significantly enhance this effect. Expectations for improvement were significantly elevated among OLP-treated participants across the 10-day study. However, at the individual level, expectations only mediated OLP outcomes once treatment experience had been acquired. Results reconcile inconsistencies in the literature regarding mechanisms.\n                  <\/jats:p>","DOI":"10.1177\/13591053251414005","type":"journal-article","created":{"date-parts":[[2026,1,28]],"date-time":"2026-01-28T16:19:13Z","timestamp":1769617153000},"page":"4454-4471","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["The role of expectations and tailored feedback on the open-label Placebo effect"],"prefix":"10.1177","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8328-3998","authenticated-orcid":false,"given":"Kirsten","family":"Barnes","sequence":"first","affiliation":[{"name":"University of New South Wales, Sydney, NSW, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kate","family":"Faasse","sequence":"additional","affiliation":[{"name":"University of New South Wales, Sydney, NSW, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,1,28]]},"reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"publisher","DOI":"10.18637\/jss.v103.i13"},{"key":"e_1_3_2_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jad.2019.06.070"},{"key":"e_1_3_2_4_1","doi-asserted-by":"publisher","DOI":"10.1001\/jamanetworkopen.2024.32427"},{"key":"e_1_3_2_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/PSY.0000000000001078"},{"key":"e_1_3_2_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/aphw.12444"},{"key":"e_1_3_2_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cognition.2021.104753"},{"key":"e_1_3_2_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/aphw.12497"},{"key":"e_1_3_2_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpsychores.2019.109808"},{"key":"e_1_3_2_10_1","volume-title":"Open-Label Placebo Effects on Psychological and Physical Well-Being: A Conceptual Replication Study","author":"Br\u00e4scher AK","year":"2022","unstructured":"Br\u00e4scher AK, Ferti IE, Witth\u00f6ft M (2022) Open-Label Placebo Effects on Psychological and Physical Well-Being: A Conceptual Replication Study.
