Abstract：
UNASSIGNED: Identifying the knowledge, attitudes, and practices (KAP) gaps of healthy eating can inform the design of effective interventions. This study aimed to test the validity and psychometric properties of a KAP of Healthy Eating Questionnaire (KAP-HEQ) tailored to the Chinese culture.
UNASSIGNED: The dimensions and potential items of each KAP scale were identified from published KAP and health literacy questionnaires, which were supplemented by the findings of a previous qualitative healthy eating study. Content validity of the KAP-HEQ was evaluated by eight experts and eight Chinese parent-adolescent dyads in Hong Kong through content validity ratio (CVR), content validity index (CVI), and qualitative feedback. The feasibility, construct validity, reliability, and sensitivity of the KAP-HEQ were evaluated in this pilot study among 60 adolescent-parent dyads (120 persons) through an online survey. The first 30 dyads who completed the KAP-HEQ were invited to repeat the KAP-HEQ 2 weeks later to assess the test-retest reliability.
UNASSIGNED: The final 44-item KAP-HEQ was completed in 10-15 min by both adolescents and their adult parents. The CVR ranged from -0.38 to 1, and the CVI ranged from 0.56 to 1. Over 80% of the items achieved convergent validity (a significantly positive correlation with its hypothesized scale) and discriminant validity (a higher correlation with its hypothesized scale than with the other two scales). Cronbach\'s alpha for the internal consistency of the Overall, Attitude, and Practice scales was >0.7, while that of the Knowledge scale was 0.54. The intraclass correlation coefficient (ICC) on test-retest reliability of the Overall and individual scales were all >0.75 except that of the Knowledge scale (ICC = 0.58). The significant differences in KAP scale scores with small to large effect sizes were found between known groups as hypothesized, except the Attitude score between groups by household income, which supported the sensitivity of the KAP-HEQ.
UNASSIGNED: The KAP-HEQ has shown good validity, reliability, and sensitivity among Chinese adolescents and adults, which can be applied to evaluate KAP status and gaps to inform the design and assess the effectiveness of healthy eating interventions.

摘要：
■识别知识，态度，健康饮食和实践（KAP）的差距可以为设计有效的干预措施提供信息。本研究旨在测试针对中国文化量身定制的健康饮食问卷（KAP-HEQ）的有效性和心理测量学特性。
■每个KAP量表的维度和潜在项目从已发布的KAP和健康素养问卷中确定，这是由以前的定性健康饮食研究的结果补充。KAP-HEQ的内容效度由8位专家和8位在香港的中国父母-青少年二元组通过内容效度比（CVR）进行评估，内容效度指数(CVI)，和定性反馈。可行性,构造效度，可靠性,在这项初步研究中，通过一项在线调查，在60名青少年父母双体（120人）中评估了KAP-HEQ的敏感性。完成KAP-HEQ的前30个分体被邀请在2周后重复KAP-HEQ，以评估重测可靠性。
■青少年及其成年父母在10-15分钟内完成了最终的44项KAP-HEQ。CVR范围为-0.38至1,CVI范围为0.56至1。超过80％的项目实现了收敛效度（与其假设量表呈显着正相关）和判别效度（与假设量表的相关性高于其他两个量表）。克朗巴赫的阿尔法对于整体的内部一致性，态度,实践量表>0.7，而知识量表为0.54。除知识量表（ICC=0.58）外，总体量表和个体量表的重测信度的组内相关系数（ICC）均>0.75。假设已知组之间发现了KAP量表得分与小到大效应大小的显着差异，除了按家庭收入划分的群体之间的态度得分，支持KAP-HEQ的敏感性。
■KAP-HEQ表现出良好的有效性，可靠性,中国青少年和成年人的敏感性，可用于评估KAP状态和差距，以告知设计和评估健康饮食干预措施的有效性。
