However, no validated Turkish tool is currently available. This study aimed to culturally adapt the Dietitians' Survey of Comfort, Opinions and Preparedness in Education in Supplements (\u2010SCOPE) Questionnaire into Turkish (Diyetisyenlerin E\u011fitim, Supleman Tercihleri ve Konforu Anketi; DESTEK) and evaluate its psychometric properties.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This methodological study included 223 dietitians. Exploratory factor analysis (Principal Axis Factoring with Direct Oblimin rotation) was conducted to identify the underlying structure, followed by confirmatory factor analysis to test model fit. Internal consistency was assessed using Cronbach's alpha. Convergent validity was examined through composite reliability and average variance extracted, and discriminant validity was evaluated using the Fornell\u2013Larcker criterion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A four\u2010factor structure explaining 38.3% of total variance was identified.
