Device-estimated sleep parameters were obtained via portable sleep respiratory monitoring. Participants also reported the previous night\u2019s total sleep time (TST), sleeponset latency (SOL), and sleep efficiency (SE) using a self-designed form. Agreement between subjective and device-estimated measures was evaluated with Bland\u2013Altman analysis. Multivariate regression was conducted to identify factors associated with subjective\u2013device-estimated sleep discrepancies.Results:Compared with device-estimated measures, subjective reports differed significantly across all three sleep parameters (Wilcoxon signed-rank test: TST, Z = \u22126.94, p &lt; 0.001; SOL, Z = \u22122.98, p = 0.003; SE, Z = \u22125.02, p &lt; 0.001). These results indicate a pronounced subjective\u2013device-estimated sleep discrepancy in late-life depression, with subjective underestimation of TST and SE and overestimation of SOL. Greater depressive symptom severity was associated with greater subjective underestimation of TST (p = 0.037), whereas later age at first onset was associated with greater subjective underestimation of SE (p = 0.013). The association between age at first onset and subjective overestimation of SOL observed in the main analysis (p = 0.047) was no longer significant after additional inclusion of sex in the model (p = 0.054).Conclusions:Patients with late-life depression exhibited subjective\u2013device-estimated discrepancies in sleep parameters. Heavier depressive symptom burden was linked to greater underestimation of total sleep time, while later age at first onset was more closely related to underestimation of sleep efficiency. A later age at first onset showed a trend toward an association with overestimation of sleep onset latency, but this finding still requires further validation. In clinical practice, combining device-estimated sleep monitoring with subjective sleep assessment should be considered in order to obtain a more comprehensive understanding of patients\u2019 sleep status.<\/jats:p>","DOI":"10.31083\/ap50350","type":"journal-article","created":{"date-parts":[[2026,7,7]],"date-time":"2026-07-07T12:42:51Z","timestamp":1783428171000},"source":"Crossref","is-referenced-by-count":0,"title":["Subjective\u2013Device-Estimated Sleep Discrepancies in Late-Life Depression: Agreement and Associated Factors"],"prefix":"10.31083","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-5407-0911","authenticated-orcid":true,"given":"Qianlong","family":"Wang","sequence":"first","affiliation":[{"name":"School of Mental Health, Jining Medical University, 272075 Jining, Shandong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9930-5602","authenticated-orcid":true,"given":"Yuandong","family":"Gong","sequence":"additional","affiliation":[{"name":"Shandong Mental Health Center, Shandong University, Shandong Provincial Key Medical and Health Discipline of Gerontology, 250014 Jinan, Shandong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-6256-1274","authenticated-orcid":true,"given":"Jiacui","family":"Ji","sequence":"additional","affiliation":[{"name":"Shandong Mental Health Center, Shandong University, Shandong Provincial Key Medical and Health Discipline of Gerontology, 250014 Jinan, Shandong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-9047-3836","authenticated-orcid":true,"given":"Yan","family":"Zhang","sequence":"additional","affiliation":[{"name":"Shandong Mental Health Center, Shandong University, Shandong Provincial Key Medical and Health Discipline of Gerontology, 250014 Jinan, Shandong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-4882-4850","authenticated-orcid":true,"given":"Meixu","family":"Lu","sequence":"additional","affiliation":[{"name":"Shandong Mental Health Center, Shandong University, Shandong Provincial Key Medical and Health Discipline of Gerontology, 250014 Jinan, Shandong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-8044-4487","authenticated-orcid":true,"given":"Meiyu","family":"Song","sequence":"additional","affiliation":[{"name":"School of Mental Health, Jining Medical University, 272075 Jining, Shandong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-4253-7592","authenticated-orcid":true,"given":"Xia","family":"Zhang","sequence":"additional","affiliation":[{"name":"Shandong Mental Health Center, Shandong University, Shandong Provincial Key Medical and Health Discipline of Gerontology, 250014 Jinan, Shandong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-7779-8315","authenticated-orcid":true,"given":"Yuping","family":"Zhao","sequence":"additional","affiliation":[{"name":"Shandong Mental Health Center, Shandong University, Shandong Provincial Key Medical and Health Discipline of Gerontology, 250014 Jinan, Shandong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-7088-4333","authenticated-orcid":true,"given":"Qi","family":"Miao","sequence":"additional","affiliation":[{"name":"Shandong Mental Health Center, Shandong University, Shandong Provincial Key Medical and Health Discipline of Gerontology, 250014 Jinan, Shandong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"16242","published-online":{"date-parts":[[2026,6,30]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","unstructured":"Ramar K, Malhotra RK, Carden KA, Martin JL, Abbasi-Feinberg F, Aurora RN, et al.
