Development, validation and reliability of the Chrononutrition Profile - Questionnaire

Area of Science:

• Nutrition Science
• Circadian Biology
• Health Psychology

Background:

• Chrononutrition, the study of food intake timing relative to circadian rhythms, is linked to health outcomes like weight gain.
• Existing methods for assessing daily chrononutrition behaviors are limited, hindering research and clinical application.
• A validated and reliable tool is needed to evaluate chrononutrition in real-world settings.

Purpose of the Study:

• To develop and test the reliability and validity of the Chrononutrition Profile - Questionnaire (CP-Q).
• To create a comprehensive measure for assessing key chrononutrition behaviors relevant to health.
• To provide a practical tool for professionals and researchers to evaluate eating timing.

Main Methods:

• Development of the Chrononutrition Profile - Questionnaire (CP-Q).
• The CP-Q assesses six core chrononutrition components: breakfast skipping, largest meal timing, evening eating, eating latency, night eating, and eating window duration.
• Initial testing for reliability and validity of the CP-Q.

Main Results:

• The CP-Q was developed to assess general chrononutrition behaviors and preferred food intake timing.
• The questionnaire covers six key components influencing health.
• Initial reliability and validity testing were conducted.

Conclusions:

• The Chrononutrition Profile - Questionnaire (CP-Q) is a newly developed tool for assessing daily eating timing.
• The CP-Q offers a cost-effective and comprehensive method for evaluating chrononutrition.
• This measure can be used independently or with other dietary assessments to understand eating behaviors and inform health strategies.
