The questionnaires elicit subjectively reported “usual frequency” consuming an item from list preference (FFPQ) needed facilitate studies assessing the patterns ischemic stroke patients. Objectives: This study aimed develop validate premorbid habits patients.Methods: total 20 Ishemic patients participated in development FFQ validation study, 100 subjects participating reproducibility study. FFQ, consisting 127 items 12 groups, was compared with one-day record (3DR) as reference method. assessed through repeat administration for three times. Reliability scale measured by split half method, whole test calculated using Spearman-Brown formula). validity FF Scale established internal consistency analysis method,. For this purpose two sets inter correlation were calculated. score each section correlated total. In second section, grand score. During readability, feasibility, clarity wordings, layout style accessed. Results: Guttman coefficient 0.321. Therefore, reliability high developed has reliability. pearson ranged 0.445 0.533. values between 0.001 0.901 most correlations found be significant, thereby indicating reasonably construct validity. results demonstrated good acceptance FFQConclusion: These findings indicate that valid reliable measuring average consumption population
