ABSTRACT
PURPOSE: This study aimed to translate and culturally adapt the Beverage Intake Questionnaire (BEVQ-15) to the Turkish population and to assess its validity and reproducibillity.
METHODS: This cross-sectional study included adults and older residing in Ankara, Turkey. The study process involved the translation of the BEVQ-15 from English into Turkish and its adaptation to the Turkish community. Adaptations to the original BEVQ-15 included separating the black tea and coffee category into distict categories, as well as herbal tea. Additionally, plain mineral water, flavored mineral water, kefir, and turnip juice were presented as individual categories. The adaptation of BEVQ-15 to Turkish preferences resulted in the BEVQ-21. Participants come to three visits, each two weeks apart. The BEVQ-21 was administered at visits 1 and 3, and a three day dietary record was returned during visit 2.. The BEVQ-21 was conducted at visit one (BEVQ-1) and visit three (BEVQ-2). Validity and reproducability statistical analyses were conducted using Wilcoxon signed-rank tests, Bland-Altman plots, and Spearman correlations.
RESULTS: Fifty-one participants completed all study visits. Minimal yet significant differences were identified between the two assessment tools (BEVQ-2 and DR) across various beverage categories, with mean differences ranging from 3 to 82 mL and 0 to 16 kcal. According to Bland-Altman plots between BEVQ-21 and dietary records, differences for water (mL), regular mineral water (mL), whole and flavored milk (mL and kcal), soft drinks (mL and kcal), black tea (mL), herbal teas (mL), and total beverage intake (mL) were found to be approximately consistent within the boundaries (p < 0.05). For reproducibility, sugary beverage and total beverage consumption were significantly associated between the first and second administration of the BEVQ-21 (r = 0.44-0.65, p ≤ 0.05).
CONCLUSIONS: The adapted BEVQ-21 for the Turkish population demonstrated validity and reproducibility for most types of beverage intake among adults in Turkey.
