| Resum≠ | The Food Frequency Questionnaire is a self-administered dietary assessment tool designed to measure habitual food and nutrient intake over an extended period (typically 6–12 months). Developed by epidemiologists, particularly Walter Willett at Harvard, the FFQ has become a cornerstone of nutritional epidemiology research, enabling large-scale studies to assess dietary patterns and examine diet-disease relationships. FFQs vary in length (50–200+ items) and focus, but all share the purpose of estimating average dietary intake in a time-efficient manner suitable for population studies. | The Nutrition Self-Efficacy Scale, sometimes called the Diabetes Self-Efficacy Scale (DASES), is an 8-item instrument measuring confidence in performing diet-related behaviors and self-management skills. Developed by Lorig and colleagues at the Stanford Patient Education Center in 2003, it is based on self-efficacy theory and measures respondents' confidence in their ability to eat healthily, manage portions, choose healthful foods, and overcome dietary barriers. The scale is used in diabetes care, weight management, and general nutrition intervention research. |
