Experience sampling methods, which involve completing multiple smartphone-based questionnaires per day over several days, may offer detailed insights into how these experiences unfold in daily life.<\/jats:p>\n <\/jats:sec>\n \n Aim:<\/jats:title>\n To evaluate feasibility and acceptability of experience sampling methods in advanced cancer, and its potential to uncover moment-to-moment symptom and well-being fluctuations.<\/jats:p>\n <\/jats:sec>\n \n Design:<\/jats:title>\n Observational study including baseline measurement, a 7-day experience sampling period with up to 10 assessments per day of symptoms and well-being, and follow-up measurement. We evaluated feasibility through response data and acceptability through a follow-up questionnaire measuring burden, ease-of-use, instruction clarity, and measurement reactivity. We analyzed fluctuations using within-person standard deviations.<\/jats:p>\n <\/jats:sec>\n \n Setting\/participants:<\/jats:title>\n We invited 79 people with advanced breast or lung cancer via two Belgian hospitals; 40 (51%) enrolled.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n Thirty-seven participants provided 1703 valid (71% of 2400 scheduled) experience sampling assessments. On 7-point scales, participants reported low burden (\n M<\/jats:italic>\n \u2009=\u20092.1, SD\u2009=\u20090.8), high ease-of-use (\n M<\/jats:italic>\n \u2009=\u20095.6, SD\u2009=\u20091.2) and instruction clarity (\n M<\/jats:italic>\n \u2009=\u20096.5, SD\u2009=\u20090.5), and minimal measurement reactivity (\n M<\/jats:italic>\n \u2009=\u20091.3, SD\u2009=\u20090.3). On 0\u2013100 scales, we observed the greatest means of within-person fluctuations across days for tiredness (\n M<\/jats:italic>\n iSD<\/jats:sub>\n \u2009=\u200916.7, SD\u2009=\u20097.7), feeling relaxed (\n M<\/jats:italic>\n iSD<\/jats:sub>\n \u2009=\u200913.0, SD\u2009=\u20097.3), and activity limitations (\n M<\/jats:italic>\n iSD<\/jats:sub>\n \u2009=\u200912.4, SD\u2009=\u20099.9). Higher mean symptom intensity generally corresponded with greater within-person fluctuations.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n Experience sampling methods proved feasible and acceptable for people with advanced cancer, effectively capturing individuals\u2019 unique symptom and well-being fluctuations in daily life. The methods are a promising avenue to enhance personalized care and improve quality of life by revealing the mechanisms behind individuals\u2019 fluctuations.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/02692163261416264","type":"journal-article","created":{"date-parts":[[2026,2,12]],"date-time":"2026-02-12T15:25:17Z","timestamp":1770909917000},"page":"535-545","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Uncovering fluctuations in daily symptoms and well-being among people with advanced cancer: An experience sampling methods study"],"prefix":"10.1177","volume":"40","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5658-5544","authenticated-orcid":false,"given":"Joran","family":"Geeraerts","sequence":"first","affiliation":[{"name":"Vrije Universiteit Brussel (VUB), End-of-Life Care Research Group, Brussels, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8825-3699","authenticated-orcid":false,"given":"Lara","family":"Pivodic","sequence":"additional","affiliation":[{"name":"Vrije Universiteit Brussel (VUB), End-of-Life Care Research Group, Brussels, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kim de","family":"Nooijer","sequence":"additional","affiliation":[{"name":"Vrije Universiteit Brussel (VUB), End-of-Life Care Research Group, Brussels, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-9510-581X","authenticated-orcid":false,"given":"Lise","family":"Rosquin","sequence":"additional","affiliation":[{"name":"Department of Sociology, KU Leuven, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lore","family":"Decoster","sequence":"additional","affiliation":[{"name":"Vrije Universiteit Brussel (VUB), Universitair Ziekenhuis Brussel (UZ Brussel), Translational Oncology Research Center (TORC), Team Laboratory for Medical and Molecular Oncology (LMMO), Brussels, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christel","family":"Fontaine","sequence":"additional","affiliation":[{"name":"Vrije Universiteit Brussel (VUB), Universitair Ziekenhuis Brussel (UZ Brussel), Translational Oncology Research Center (TORC), Team Laboratory for Medical and Molecular Oncology (LMMO), Brussels, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sofie","family":"Joris","sequence":"additional","affiliation":[{"name":"Vrije Universiteit Brussel (VUB), Universitair Ziekenhuis Brussel (UZ Brussel), Translational Oncology Research Center (TORC), Team Laboratory for Medical and Molecular Oncology (LMMO), Brussels, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1508-7263","authenticated-orcid":false,"given":"Eline","family":"Naert","sequence":"additional","affiliation":[{"name":"Department of Medical Oncology, University Hospital Ghent, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4744-8561","authenticated-orcid":false,"given":"Geert","family":"Crombez","sequence":"additional","affiliation":[{"name":"Department of Experimental-Health Psychology, Ghent University, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4433-8807","authenticated-orcid":false,"given":"Mark","family":"De Ridder","sequence":"additional","affiliation":[{"name":"Department of Radiotherapy, Vrije Universiteit Brussel (VUB), Universitair Ziekenhuis Brussel (UZ Brussel), Brussels, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7770-348X","authenticated-orcid":false,"given":"Lieve","family":"Van den Block","sequence":"additional","affiliation":[{"name":"Vrije Universiteit Brussel (VUB), End-of-Life Care Research Group, Brussels, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2026,2,12]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/pon.5792"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.21147\/j.issn.1000-9604.2022.03.09"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cllc.2016.12.010"},{"key":"e_1_3_3_5_2","first-page":"499","article-title":"Do cancer centres and palliative care wards routinely measure patients\u2019 quality of life?
