DESCRIPTION (provided by applicant): Knowledge of how the home environment affects children's healthy weight is limited by lack of well-developed, comprehensive measures. The objective of this research is to develop HomeSTEAD, the Home Self- administered Tool for Environmental assessment of Activity and Diet, and provide evidence for the reliability of scores and validity of inferences from this instrument. The proposal comes from a group of highly experienced researchers and will build off of a preliminary home assessment instrument developed by the team. The original instrument was administered via telephone interview and initial testing, though promising, identified areas for improvement. The current project includes three aims. Aim 1 consists of developing candidate items for a self-administered measure of home environmental factors hypothesized to impact diet and physical activity behaviors of children (age 3-12 y). Item selection will draw on data from our preliminary instrument, existing items and/or instruments, published literature, and expert opinion. For Aim 2, we will maximize comprehension of items, terms, and definitions in the newly developed HomeSTEAD using one-on- one guided cognitive interviews in a diverse sample of parents (n=60) to insure that our intention for an item agrees with participant interpretation. For Aim 3, we will examine reliability and validity evidence for the new survey by administering the survey to an ethnically diverse sample of families (n=130) with at least one child age 3-12y. A designated parent will complete the survey three times: Time 1- within 48 hours prior to the in- home observation by research staff (validity); Time 2- concurrent with the in-home observation (reliability); and Time 3 - approximately 10 days later (trait stability, reliability). Traditional estimates of reliability and validity (Kappa, ICC, correlation) will be calculated for each item and absolute agreement across trials evaluated using ANOVA. For items not feasible to observe during the home visit (e.g., policies for TV viewing), reliability and validity will be tested through exploratory and confirmatory factor analysis. Successful completion of this project will result in a reliable and valid self-administered survey that can be used by researchers to quantify aspects of the home environment that may influence weight-related behaviors in children. PUBLIC HEALTH RELEVANCE: The role of the environment in the etiology of child obesity has received increased attention. For children, the home is the most proximate and influential environment, providing the context in which eating and activity habits develop. However, understanding the relationship between home environment and diet, activity, and weight, is impaired by a lack of valid and reliable assessment tools. The proposed HomeSTEAD tool will address this gap and help elucidate the relationship between home and child obesity and plan interventions.

描述（由申请人提供）：由于缺乏完善的综合措施，对家庭环境如何影响儿童健康体重的了解有限。本研究的目的是开发家庭自我管理的活动和饮食环境评估工具宅基地，并为该工具的得分可靠性和推断的有效性提供证据。该提案来自一组经验丰富的研究人员，并将建立在该团队开发的初步家庭评估工具的基础上。最初的工具是通过电话采访和初步测试，虽然有希望，确定了改进的领域。当前项目包括三个目标。目的1包括发展候选项目的家庭环境因素的自我管理措施假设影响儿童（3-12岁）的饮食和体育活动的行为。项目选择将利用我们的初步工具，现有项目和/或工具，已发表的文献和专家意见的数据。对于目标2，我们将最大限度地理解项目，术语和定义在新开发的宅基地使用一对一的指导认知访谈在不同的样本的父母（n=60），以确保我们的意图为一个项目同意参与者的解释。对于目标3，我们将通过对至少有一个3- 12岁儿童的种族多样化家庭样本（n=130）进行调查来检查新调查的可靠性和有效性证据。指定的父母将完成调查三次：时间1-在研究人员进行家庭观察之前48小时内（有效性）;时间2-与家庭观察同时进行（可靠性）;时间3 -大约10天后（性状稳定性，可靠性）。将计算每个项目的可靠性和有效性（Kappa、ICC、相关性）的传统估计值，并使用ANOVA评价试验间的绝对一致性。对于家访期间无法观察的项目（例如，电视收视政策），通过探索性和验证性因素分析来检验信度和效度。这个项目的成功完成将导致一个可靠的和有效的自我管理的调查，可用于研究人员量化的家庭环境，可能会影响儿童体重相关的行为方面。公共卫生相关性：环境在儿童肥胖病因学中的作用越来越受到关注。对于儿童来说，家庭是最接近和最有影响力的环境，为饮食和活动习惯的发展提供了环境。然而，由于缺乏有效和可靠的评估工具，对家庭环境与饮食、活动和体重之间关系的理解受到损害。拟议的宅基地工具将解决这一差距，并帮助阐明家庭和儿童肥胖之间的关系，并计划干预措施。
