However, prior studies in the literature have been limited by brief assessment periods, high participant burden, and heterogeneity in both sampling and symptom assessment methodologies.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n This study aimed to validate a 12-item EMA questionnaire of OCD symptoms by evaluating its psychometric properties over an extended monitoring period.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Adults with OCD (22\/41, 53.7%) and demographically matched healthy controls (19\/41, 46.3%) completed up to 70 daily smartphone-delivered EMA surveys assessing the frequency and emotional impact of obsessions and compulsions. Participants with OCD also underwent clinician-administered Yale-Brown Obsessive-Compulsive Scale evaluations at weeks 0, 2, and 10.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Our scale demonstrated high internal consistency (Cronbach \u03b1=0.96) and convergent validity, with significant correlation with Yale-Brown Obsessive-Compulsive Scale scores at week 2 (\u03c1=0.59;\n P<\/jats:italic>\n =.004) and week 10 (\u03c1=0.53;\n P<\/jats:italic>\n =.01). Participant retention (89.1%) and questionnaire completion rate (89%) were also higher than those seen in the literature (75.2% and 74.2%, respectively).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Overall, we provide initial psychometric support for the use of a low-burden EMA tool to capture day-to-day OCD symptom fluctuations over extended periods. Such tools may enhance longitudinal symptom monitoring, improve treatment response tracking, and address limitations inherent in traditional retrospective assessments.<\/jats:p>\n <\/jats:sec>","DOI":"10.2196\/86471","type":"journal-article","created":{"date-parts":[[2026,3,30]],"date-time":"2026-03-30T18:51:11Z","timestamp":1774896671000},"page":"e86471-e86471","source":"Crossref","is-referenced-by-count":0,"title":["Validation of a Low-Burden, Once-Daily Obsessive-Compulsive Disorder Measure Over 70 Days: Ecological Momentary Assessment Study"],"prefix":"10.2196","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7950-863X","authenticated-orcid":false,"given":"Andrew","family":"Jiang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5710-2054","authenticated-orcid":false,"given":"Ruibei","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-2751-297X","authenticated-orcid":false,"given":"Jiaqi","family":"Fan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8203-8480","authenticated-orcid":false,"given":"Adam Charles","family":"Frank","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2026,3,30]]},"reference":[{"issue":"1","key":"R1","doi-asserted-by":"publisher","first-page":"53","DOI":"10.1038\/mp.2008.94","article-title":"The epidemiology of obsessive-compulsive disorder in the National Comorbidity Survey Replication","volume":"15","author":"Ruscio","journal-title":"Mol Psychiatry"},{"issue":"11","key":"R2","doi-asserted-by":"publisher","first-page":"1006","DOI":"10.1001\/archpsyc.1989.01810110048007","article-title":"The Yale-Brown Obsessive Compulsive Scale.
