The objective of this study was to develop and validate a Knowledge, Attitude, and Practice Questionnaire (KAPQ) on nutrition, physical activity, and body image for 13-14-year-old female adolescents.
The KAPQ initially consisted of 73 items, covering knowledge (30), attitude (22), and practice (21) related to nutrition, physical activity (PA), and body image (BI). The content and face validity were tested to identify the relevance of the questionnaire items to the content and their relevance to nutrition, PA, and BI. Construct validity was assessed using an exploratory factor analysis (EFA). Internal consistency was determined by Cronbach's α value, and stability was determined based on test-retest reliability.
Based on the EFA, each scale had several dimensions. The Cronbach's α ranged between 0.977 and 0.888 for knowledge, 0.902 and 0.977 for attitude, and 0.949 and 0.950 for practice. The test-retest reliability revealed that the kappa of knowledge was 0.773-1.000, while the intraclass correlation (ICC) values for attitude and practice were 0.682-1.000 and 0.778-1.000, respectively.
The final KAPQ, which included 72 items, was valid and reliable for assessing the KAP levels for nutrition, PA, and BI of 13-14-year-old female students in KSA.
本研究的目的是开发并验证一份针对13 - 14岁女性青少年的营养、身体活动和身体形象知识、态度与行为问卷（KAPQ）。
KAPQ最初包含73个项目，涵盖与营养、身体活动（PA）和身体形象（BI）相关的知识（30项）、态度（22项）和行为（21项）。对内容效度和表面效度进行测试，以确定问卷项目与内容的相关性以及它们与营养、PA和BI的相关性。使用探索性因素分析（EFA）评估结构效度。通过Cronbach's α值确定内部一致性，并基于重测信度确定稳定性。
基于EFA，每个量表都有几个维度。知识量表的Cronbach's α值在0.977至0.888之间，态度量表在0.902至0.977之间，行为量表在0.949至0.950之间。重测信度显示，知识的kappa值为0.773 - 1.000，态度和行为的组内相关系数（ICC）值分别为0.682 - 1.000和0.778 - 1.000。
最终的KAPQ包含72个项目，对于评估沙特阿拉伯13 - 14岁女学生在营养、PA和BI方面的KAP水平是有效且可靠的。
