Poor sleep quality is associated with self-reported cognitive changes, which can occur before the onset of objective cognitive decline associated with Mild Cognitive Impairment and Alzheimer\u2019s disease. The objective of this study was to examine associations between self-reported sleep complaints, objective sleep quality, and self-reported cognitive changes and their relations to symptoms of depression and anxiety in a group of community-dwelling older adults. Adults aged \u2265 50 without dementia (n = 45) were recruited and completed 1\u20132 weeks of rest-activity monitoring using a wrist-worn device, underwent a test of global cognitive functioning (Mini-Mental State Examination; MMSE), and completed questionnaires assessing insomnia (Insomnia Severity Index; ISI), subjective sleep quality (Pittsburgh Sleep Quality Index; PSQI), self-reported cognitive changes (Cognitive Function Instrument; CFI), and symptoms of depression and anxiety (Beck Depression Inventory-II; BDI-II and Generalized Anxiety Disorder 7-item assessment; GAD-7). Pearson partial correlations assessed relations among subjective and objective sleep quality, insomnia ratings, CFI ratings, and global cognition, while controlling for BDI-II and GAD-7 ratings. Exploratory analyses examined the correlation between PSQI component scores and CFI ratings and global cognition. Greater ISI (r = 0.50, p \u2264 0.001) ratings significantly correlated with higher CFI scores. PSQI total ratings and actigraphy-based measures (n = 41) did not significantly correlate with CFI scores. Exploratory PSQI subscale analyses revealed that worse subjective sleep quality (r = 0.31, p = 0.048), shorter sleep duration (r = 0.32, p = 0.04), and greater use of sleep medications (r = 0.31, p = 0.048) correlated with higher CFI scores. Poorer sleep quality due to less time spent asleep, fragmented or disturbed sleep, and requiring medications to sleep, may be associated with greater memory concerns. Alternatively, worries about cognition may deleteriously affect sleep. Subjective measures of sleep quality may be useful to identify older adults at increased risk of cognitive decline.<\/jats:p>","DOI":"10.3390\/clockssleep7040056","type":"journal-article","created":{"date-parts":[[2025,10,2]],"date-time":"2025-10-02T15:07:48Z","timestamp":1759417668000},"page":"56","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Self-Reported Insomnia and Poor Sleep Quality Are Associated with Self-Reported Cognitive Changes in Older Adults"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-4196-5931","authenticated-orcid":false,"given":"Julia","family":"Glueck","sequence":"first","affiliation":[{"name":"Department of Psychological and Brain Sciences, Boston University, Boston, MA 02215, USA"},{"name":"Division of Sleep and Circadian Disorders, Department of Medicine, Brigham and Women\u2019s Hospital, Boston, MA 02115, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1834-8983","authenticated-orcid":false,"given":"Celina","family":"Pluim McDowell","sequence":"additional","affiliation":[{"name":"Department of Psychological and Brain Sciences, Boston University, Boston, MA 02215, USA"},{"name":"Division of Sleep and Circadian Disorders, Department of Medicine, Brigham and Women\u2019s Hospital, Boston, MA 02115, USA"},{"name":"Department of Psychiatry, Massachusetts General Hospital, Harvard Medical School, Boston, MA 02114, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yakeel T.","family":"Quiroz","sequence":"additional","affiliation":[{"name":"Department of Psychological and Brain Sciences, Boston University, Boston, MA 02215, USA"},{"name":"Department of Psychiatry, Massachusetts General Hospital, Harvard Medical School, Boston, MA 02114, USA"},{"name":"Department of Neurology, Massachusetts General Hospital, Harvard Medical School, Boston, MA 02114, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5699-6204","authenticated-orcid":false,"given":"Alice","family":"Cronin-Golomb","sequence":"additional","affiliation":[{"name":"Department of Psychological and Brain Sciences, Boston University, Boston, MA 02215, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4177-4179","authenticated-orcid":false,"given":"Jeanne F.","family":"Duffy","sequence":"additional","affiliation":[{"name":"Division of Sleep and Circadian Disorders, Department of Medicine, Brigham and Women\u2019s Hospital, Boston, MA 02115, USA"},{"name":"Division of Sleep Medicine, Harvard Medical School, Boston, MA 02115, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"181","DOI":"10.1016\/B978-0-444-53702-7.00011-7","article-title":"Do Sleep Complaints Contribute to Age-Related Cognitive Decline?","volume":"185","author":"Altena","year":"2010","journal-title":"Prog.
