This study was conducted to determine the feasibility of using a single-item smartphone-based ecological momentary assessment (EMA) in lieu of accelerometers in long-term assessment of daily exercise. Data were collected from a randomized controlled trial of intermittently exercising, otherwise healthy adults (N = 79; 57% female, mean age: 31.9 \u00b1 9.5 years) over 365 days. Smartphone-based EMA self-reports of exercise entailed daily end-of-day responses about physical activity; the participants also wore a Fitbit device to measure physical activity. The Kappa statistic was used to quantify the agreement between accelerometer-determined (24 min of moderate-to-vigorous physical activity [MVPA] within 30 min) and self-reported exercise. Possible demographic predictors of agreement were assessed. Participants provided an average of 164 \u00b1 87 days of complete data. The average within-person Kappa was \u03ba = 0.30 \u00b1 0.22 (range: \u22120.15\u20130.73). Mean Kappa ranged from 0.16 to 0.30 when the accelerometer-based definition of an exercise bout varied in duration from 15 to 30 min of MVPA within any 30 min period. Among the correlates examined, sex was significantly associated with agreement; mean agreement was higher among women (\u03ba = 0.37) than men (\u03ba = 0.20). Agreement between EMA self-reported and accelerometer-measured exercise was fair, suggesting that long-term exercise monitoring through a single-item EMA may be acceptable.<\/jats:p>","DOI":"10.3390\/s24030946","type":"journal-article","created":{"date-parts":[[2024,2,1]],"date-time":"2024-02-01T09:43:22Z","timestamp":1706780602000},"page":"946","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Use of a Single-Item Ecological Momentary Assessment to Measure Daily Exercise: Agreement with Accelerometer-Measured Exercise"],"prefix":"10.3390","volume":"24","author":[{"given":"Kevin","family":"Sundquist","sequence":"first","affiliation":[{"name":"Capital Rx, 1 World Trade Center, New York, NY 10007, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8944-3566","authenticated-orcid":false,"given":"Joseph E.","family":"Schwartz","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Behavioral Science, Stony Brook University, Stony Brook, NY 11794, USA"},{"name":"Center for Behavioral Cardiovascular Health, Columbia University Medical Center, New York, NY 10032, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew M.","family":"Burg","sequence":"additional","affiliation":[{"name":"Department of Medicine, Yale University School of Medicine, New Haven, CT 06520, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karina W.","family":"Davidson","sequence":"additional","affiliation":[{"name":"Institute of Health System Science, Feinstein Institutes for Medical Research, Northwell Health, New York, NY 11030, USA"},{"name":"Donald and Barbara Zucker School of Medicine at Hofstra\/Northwell, Northwell Health, Hempstead, NY 11549, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0190-0548","authenticated-orcid":false,"given":"Keith M.","family":"Diaz","sequence":"additional","affiliation":[{"name":"Center for Behavioral Cardiovascular Health, Columbia University Medical Center, New York, NY 10032, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,1]]},"reference":[{"key":"ref_1","first-page":"S76","article-title":"2013 AHA\/ACC Guideline on Lifestyle Management to Reduce Cardiovascular Risk: A Report of the American College of Cardiology\/American Heart Association Task Force on Practice Guidelines","volume":"129","author":"Eckel","year":"2013","journal-title":"Circulation"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"745","DOI":"10.1016\/j.mayocp.2016.02.028","article-title":"Lifelong Exercise Patterns and Cardiovascular Health","volume":"91","author":"Maessen","year":"2016","journal-title":"Mayo Clin.
