Chrononutrition, or the circadian timing of food intake, has garnered attention as a topic of study due to its associations with health (e.g. weight gain); however, a valid and reliable assessment of chrononutrition in daily life has not yet been developed. This paper details the development and initial reliability and validity testing of the Chrononutrition Profile - Questionnaire (CP-Q). The CP-Q assesses six components of chrononutrition that are likely to influence health (breakfast skipping, largest meal, evening eating, evening latency, night eating, and eating window). This questionnaire is designed to assess general chrononutrition behaviors and preferred timing of food intake. The CP-Q can be used as a sole evaluation of chrononutrition, and can also be utilized in conjunction with existing dietary measures to provide a comprehensive assessment of one's eating behaviors. This measure offers health-care professionals, researchers, and stakeholders a cost-effective and comprehensive method of evaluating chrononutrition and identifying targets for health improvement.

Chrononutrition Profile - 问卷的开发、验证和可靠性。

计时营养，或食物摄入的昼夜节律时间，因其与健康（例如体重增加）的关联而作为研究主题受到关注；然而，对日常生活中的长期营养进行有效和可靠的评估尚未开发出来。本文详细介绍了 Chrononutrition Profile - Questionnaire (CP-Q) 的开发和初始信度和效度测试。CP-Q 评估可能影响健康的时间营养的六个组成部分（不吃早餐、最大餐、晚上进食、晚上潜伏期、夜间进食和进食窗口）。该问卷旨在评估一般的时间营养行为和食物摄入的首选时间。CP-Q 可用作对时间营养的唯一评估，也可以与现有的饮食措施结合使用，以提供一个人的饮食行为的综合评估。该措施为医疗保健专业人员、研究人员和利益相关者提供了一种经济高效且全面的方法来评估长期营养并确定改善健康的目标。
