Implication

Validation study demonstrates reliable measurement of Mediterranean diet adherence in Italian pregnant women, highlighting its clinical and research utility.

Key Points

  • To translate, cross-culturally adapt, and evaluate the psychometric validity of the pregnancy-adapted Mediterranean Diet Adherence Screener (ITpreg-MEDAS) among Italian pregnant women.
  • Adapted the 17-item Spanish preg-MEDAS questionnaire into Italian using a standard six-step translation and cross-cultural adaptation process.
  • Evaluated questionnaire clarity through pre-testing in 25 Italian pregnant women and assessed construct validity, internal consistency, and test-retest reliability in a validation cohort of 116 Italian pregnant women.
  • In the validation cohort (N=116), the mean ITpreg-MEDAS score was 7.2 ± 2.5 out of 17, reflecting medium adherence to the Mediterranean diet.
  • The instrument demonstrated acceptable internal consistency (Cronbach’s α = 0.623) and strong test-retest reliability (r = 0.756).
