The primary goal is to evaluate the validity and reproducibility of the TDG-SFFQ to ensure it accurately captures habitual dietary patterns in the target population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S1368980026103413_as2\">\n                    <jats:title>Design:<\/jats:title>\n                    <jats:p>The TDG-SFFQ was administered through face-to-face interviews. Validity was assessed by comparing it with a 24-h dietary recall, while reliability was evaluated using a test-retest method after 4 weeks with fifty-six participants in Ankara, T\u00fcrkiye. Daily intake means for energy, macronutrients and micronutrients obtained from both the TDG-SFFQ and 24-h dietary recall were calculated. Concordance between the two methods was analysed using the Pearson correlation coefficient and Bland\u2013Altman plots.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S1368980026103413_as3\">\n                    <jats:title>Setting:<\/jats:title>\n                    <jats:p>Participants with adequate communication skills were recruited through digital announcements on social media and professional networks, followed by a snowball sampling method to expand the study reach.
