This study aimed to validate a culture-specific semi-quantitative electronic Food Frequency Questionnaire (e-FFQ) to estimate food group intake in the adult population of Trinidad and Tobago.\u2009A 139-item semi-quantitative e-FFQ containing local dishes and street food was administered twice to adults 18\u2009years and older and compared against four 1-day food records (FRs) using digital photographs, which served as the reference method. The validity and reproducibility of the e-FFQ food group intake estimates were determined using paired t-tests, bivariate correlations, and cross-classifications.\u2009Reproducibility correlations between the reported food group intakes in the first and repeat administration of the e-FFQ ranged from moderate ( r\u2009=\u2009.44, P\u2009\u2264\u2009.0001) for sweetened beverages to high ( r\u2009=\u2009.91 P\u2009\u2264\u2009.0001) for alcohol. The cross-classification agreements ranged from 70% (street food) to 92% (alcohol). Energy-adjusted deattenuated validity correlations between the e-FFQ and FR ranged from ( r\u2009=\u2009.08) for water to ( r\u2009=\u2009.81) for food from animal sources, with a mean validity correlation of .36. An average of 68% of the e-FFQ estimates was correctly classified within the \u00b11 quintile of the exact agreement with the FRs. Agreements between the e-FFQ and FRs ranged from 55% for street foods to 95% for water, all significant at P\u2009\u2264\u2009.0001.\u2009This study shows that the culture-specific e-FFQ is a valid tool for assessing and ranking food category intake estimates of the adult population living in Trinidad and Tobago.<\/jats:p>","DOI":"10.1177\/00469580241273247","type":"journal-article","created":{"date-parts":[[2024,9,13]],"date-time":"2024-09-13T22:33:36Z","timestamp":1726266816000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Validity and Reproducibility of a Culture-Specific Electronic Food Frequency Questionnaire: A Trinidad and Tobago Diet Assessment Study"],"prefix":"10.1177","volume":"61","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-2305-4087","authenticated-orcid":false,"given":"Lesley Ann","family":"Foster-Nicholas","sequence":"first","affiliation":[{"name":"Loma Linda University, Loma Linda, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9824-3670","authenticated-orcid":false,"given":"David","family":"Shavlik","sequence":"additional","affiliation":[{"name":"Loma Linda University, Loma Linda, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3972-5194","authenticated-orcid":false,"given":"Celine","family":"Heskey","sequence":"additional","affiliation":[{"name":"Loma Linda University, Loma Linda, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8131-3732","authenticated-orcid":false,"given":"Patricia","family":"Dyett","sequence":"additional","affiliation":[{"name":"University of the West Indies, St. Augustine, Trinidad & Tobago"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0098-8373","authenticated-orcid":false,"given":"Gina","family":"Segovia-Siapco","sequence":"additional","affiliation":[{"name":"Loma Linda University, Loma Linda, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,9,12]]},"reference":[{"key":"bibr1-00469580241273247","unstructured":"Nations Encyclopedia Trinidad and Tobago - Ethnic groups. 2018; Accessed October 23, 2018. https:\/\/www.nationsencyclopedia.com\/Americas\/Trinidad-and-Tobago-ETHNIC-GROUPS.html"},{"key":"bibr2-00469580241273247","unstructured":"Telecommunications Authority of Trinidad and Tobago.
