DESCRIPTION (provided by applicant): Most American youth do not meet the Physical Activity Guidelines for Americans, and a major public health effort is underway to promote physical activity in young people. Monitoring this effort requires a system that provides valid and detailed information on physical activity behavior. Although accelerometry can be used in large-scale surveillance studies, it is expensive, burdensome and provides no information about specific forms or contexts of physical activity. Self-report instruments are practical for use in surveillance studies, but no current self-report instrument for youth provides both excellent validity versus an objective measure of physical activity and detailed information on specific forms and contexts of activity. The purpose of this study is to develop, pilot test, and validate a physical activity self-report instrument that has strong construct validity, matches well with the cognitive abilities of youth, associates strongly with objectively-measured physical activity, and contains items that will provide information about specific forms and physical/social contexts of physical activity in youth. The proposed study has two Aims: Aim 1 is to develop a physical activity self- report instrument for youth that has robust construct validity. We will review the literature on existing PA instruments and conduct focus groups with 96 middle school boys and girls to identify common types, frequency, and intensity of activities. From the data, we will identify a pool of candidate dichotomous (Yes/No) items and administer the resulting instrument to 500 middle school students. Item Response Theory will be utilized to select the items that best represent the construct of physical activity in 11-15 year-old boys and girls. Aim 2 is to examine the validity of the self-report instrument versus an objective measure of physical activity in youth. An independent sample of 300 students will complete two forms of the final self-report instrument after wearing an accelerometer for 7 days. Half of the sample will complete the instrument by providing only Yes/No responses. The other half will provide both Yes/No and frequency of participation responses. Analyses will test the validity of the new instruments versus daily minutes of moderate-to-vigorous physical activity measured via accelerometry. The proposed study carries high public health significance because it will develop a measure of physical activity in youth that has excellent validity and is practical for use in surveillance systems and large sample investigations. The study is innovative because it will be the first time a physical activity self-report instrument for youth is built with a proven program of test validation using state-of-the-art Item Response Theory. The information provided by the instrument will contribute importantly to the development and evaluation of public health policies and programs aimed at increasing physical activity in U.S. youth.

描述（由申请人提供）：大多数美国青少年不符合《美国人身体活动指南》，一项重大公共卫生工作正在进行中，以促进年轻人的身体活动。监控这种努力需要一个能够提供有关身体活动行为的有效且详细信息的系统。尽管加速度测量可用于大规模监测研究，但它价格昂贵、繁重，并且无法提供有关身体活动的具体形式或背景的信息。自我报告工具对于监测研究来说是实用的，但目前没有一种针对青少年的自我报告工具既可以提供出色的有效性，也可以客观地衡量身体活动，并提供有关具体活动形式和背景的详细信息。本研究的目的是开发、试点测试和验证一种身体活动自我报告工具，该工具具有很强的结构效度，与青少年的认知能力相匹配，与客观测量的身体活动密切相关，并且包含可提供有关青少年身体活动的具体形式和身体/社会背景的信息。拟议的研究有两个目标：目标 1 是为青少年开发一种具有强大结构效度的身体活动自我报告工具。我们将回顾现有 PA 工具的文献，并对 96 名中学生进行焦点小组讨论，以确定活动的常见类型、频率和强度。根据数据，我们将确定一组候选二分法（是/否）项目，并对 500 名中学生使用生成的工具。将利用项目反应理论来选择最能代表 11-15 岁男孩和女孩体育活动结构的项目。目标 2 是检验自我报告工具与青少年身体活动客观衡量标准的有效性。 300 名学生的独立样本将在佩戴加速度计 7 天后完成两种形式的最终自我报告仪器。一半的样本将通过仅提供是/否回答来完成仪器。另一半将提供是/否以及参与响应的频率。分析将测试新仪器与通过加速度测量仪测量的每日中度至剧烈体力活动分钟数的有效性。拟议的研究具有很高的公共卫生意义，因为它将开发一种具有良好有效性的青少年体力活动测量方法，并且可用于监测系统和大样本调查。这项研究具有创新性，因为这将是首次使用最先进的项目反应理论，通过经过验证的测试验证程序构建青少年身体活动自我报告工具。该工具提供的信息将对旨在增加美国青少年身体活动的公共卫生政策和计划的制定和评估做出重要贡献。
