During pregnancy, physiological changes can affect eating and sleeping habits, which may eventually have negative consequences for maternal and foetal health. To better understand these changes, it is essential to develop a reliable questionnaire that addresses lifestyle habits such as snacking and daytime napping. This study aimed to determine the validity and reliability of the Chrononutrition Profile Questionnaire-Pregnancy (CPQ-P).
A total of 399 women in their second and third trimester of pregnancy were recruited from government maternal and child health clinics in Kuala Lumpur and Putrajaya and completed a self-administered online questionnaire. Content validity was conducted with an expert panel consisting of 4 members. Confirmatory factor analysis (CFA) using maximum likelihood was conducted to determine the construct validity. Internal consistency was determined by Cronbach's alpha coefficient (CAC), while the test-retest reliability was conducted using intraclass correlation coefficient (ICC).
The questionnaire had an appropriate content validity index of 0.91. The CPQ-P consists of 22 items, measuring 5 constructs, including morning chrono-habits, sleeping habits, evening eating, temporal eating, and pregnancy symptoms. The factor model showed good fit with χ/df = 2.486, GFI = 0.893, CFI = 0.912, and RMSEA = 0.065. The 22 items in CPQ-P showed fair to excellent test-retest reliability (ICC: 0.42 to 0.98). The 5 constructs in CPQ-P were found to have a good to excellent internal consistency (α = 0.612-0.963).
The CPQ-P is a valid and reliable tool for assessing lifestyle habits during pregnancy. The questionnaire can be used to identify areas where pregnant women may need additional support or intervention to adopt healthy behaviours and reduce the risk of adverse maternal and foetal outcomes.

在怀孕期间，生理变化会影响饮食和睡眠习惯，这可能最终对母婴健康产生负面影响。为了更好地了解这些变化，开发一种可靠的问卷来评估饮食习惯，如零食和白天小睡，是非常重要的。本研究旨在确定 Chrononutrition Profile Questionnaire-Pregnancy（CPQ-P）的有效性和可靠性。
共招募了 399 名来自吉隆坡和布城政府母婴健康诊所的处于妊娠第二和第三阶段的妇女，并在线完成了一份自我管理的问卷。内容有效性由由 4 名成员组成的专家小组进行。采用最大似然法进行验证性因子分析（CFA），以确定结构有效性。采用 Cronbach's alpha 系数（CAC）确定内部一致性，采用组内相关系数（ICC）确定重测信度。
问卷具有适当的内容有效性指数为 0.91。CPQ-P 由 22 个项目组成，测量 5 个结构，包括早晨的生物钟习惯、睡眠习惯、晚上的饮食、时间性饮食和妊娠症状。因子模型显示出良好的拟合度，χ/df=2.486，GFI=0.893，CFI=0.912，RMSEA=0.065。CPQ-P 的 22 个项目具有良好至优秀的重测信度（ICC：0.42 至 0.98）。CPQ-P 的 5 个结构具有良好至优秀的内部一致性（α=0.612-0.963）。
CPQ-P 是评估妊娠期间生活方式的有效且可靠的工具。该问卷可用于确定孕妇可能需要额外支持或干预的领域，以采用健康行为并降低不良母婴结局的风险。
