Tools to assess diet in a reliable and efficient way are needed, particularly in children and
adolescents. In this study, we assess the reproducibility and validity of a semiquantitative food
frequency questionnaire (FFQ) among adolescents in Spain. We analyzed data of 51 male adolescents
aged 15–17 years from a prospective birth cohort study. Participants answered the FFQ twice in a
self-administered way over a 12-month period. Reproducibility was assessed by comparing nutrient
and food intakes from the FFQs, and validity by comparing nutrient intakes from the average of two
FFQs and the average of two 24-Hour Dietary Recalls obtained in the period. Pearson correlation
coefficients were calculated. The average of reproducibility correlation coefficients for food group
intakes was 0.33, with the highest correlation for vegetable intake (r = 0.81); and the average for
nutrient intake was 0.32, with the highest coefficients for α- and β-carotene (r = 0.65). Validity
correlation coefficients ranged from 0.07 for carbohydrates to 0.53 for dietary fiber. The average of the
validity correlation coefficients was r = 0.32. This study suggests that our FFQ may be a useful tool
for assessing dietary intake of most nutrient and food groups among Spanish male adolescents in a
self-administered way, despite reproducibility and, particularly validity, being low for some nutrients
and food groups.
