| الملخص: | Rationale: Non-communicable diseases (NCDs) are a leading cause of mortality in Lebanon, with diet playing a significant role in their prevention. Due to the high burden of NCDs, accurate and culturally appropriate dietary assessment tools are needed. The Modified Mediterranean Prime Screen (MMPS), a culture-specific dietary screener, was developed to assess dietary intake associated with NCD risk in adults in Lebanon. Methods: This study aimed to validate the MMPS against a reference Food Frequency Questionnaire (FFQ) to evaluate its reproducibility and agreement in assessing diet quality indices such as the Mediterranean Diet Score (MDS) and Dietary Approaches to Stop Hypertension (DASH). Reproducibility and agreement were assessed through Intraclass Correlation Coefficients (ICCs) and Cohen’s Kappa (κ). Results: The study included 214 adults (65% females, mean age 38.9 ± 13.4 years). For the MDS components, the FFQ demonstrated excellent reproducibility for vegetables and legumes and good to moderate for all the other components except for fruits (poor reproducibility). The MMPS also showed excellent reproducibility for fish and good to moderate reproducibility for all the other components except for cereals (poor reproducibility). Agreement between FFQ and MMPS was good to moderate for all food groups, however it was poor for the MDS total score (ICC = 0.435). For DASH components, Cohen’s Kappa between FFQ1 and FFQ2 ranged from fair (fruits, κ = 0.357) to excellent (sweetened beverages, κ = 0.857). Reproducibility of the MMPS was stronger, particularly for whole grains (κ = 0.761) and red and processed meats (κ = 0.685). In contrast, agreement between FFQ and MMPS was highest for sweetened beverages (κ = 0.481) but slight to fair for most other components. Conclusion: The MMPS demonstrated moderate reproducibility and poor agreement in estimating key dietary quality indices, including the MDS and DASH. |
