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）：关于家庭环境如何影响儿童体重的知识受到缺乏发达，全面的措施的限制。这项研究的目的是开发霍姆斯特德（Homestead），这是家庭自我管理的工具，用于环境评估活动和饮食，并提供了该工具分数的可靠性和推论的有效性的证据。该提案来自一群经验丰富的研究人员，将由团队开发的初步房屋评估工具建立。原始仪器是通过电话访谈和初步测试进行管理的，尽管很有希望，但它确定了改进的领域。当前项目包括三个目标。 AIM 1包括开发候选物品，以自我管理对家庭环境因素的衡量，假设会影响儿童的饮食和身体活动行为（3-12岁）。项目选择将借鉴我们的初步工具，现有项目和/或工具，已发表的文献以及专家意见的数据。对于AIM 2，我们将在新发展的宅基地中最大程度地理解物品，条款和定义，并在多样化的父母样本（n = 60）中进行一对指导的认知访谈（n = 60），以确保我们对项目的意图与参与者的解释一致。对于AIM 3，我们将通过向至少3-12岁的孩子的种族多样化的家庭样本（n = 130）进行调查来检查新调查的可靠性和有效性证据。指定的父母将三次完成调查：时间1-在研究人员（有效性）之前的48小时内48小时内；时间2-与家庭观察（可靠性）并发；时间3-大约10天后（特质稳定性，可靠性）。对于使用ANOVA评估的试验，将计算有关每个项目的可靠性和有效性（KAPPA，ICC，相关性）的传统估计。对于在家访问期间不可行的项目（例如，电视查看的政策），可靠性和有效性将通过探索性和确认性因素分析来测试。该项目的成功完成将导致一项可靠且有效的自我管理调查，研究人员可以使用该调查来量化家庭环境的各个方面，这可能会影响儿童体重相关的行为。公共卫生相关性：环境在儿童肥胖病学中的作用受到了越来越多的关注。对于儿童而言，房屋是最近端，最有影响力的环境，提供了饮食和活动习惯的背景。但是，了解家庭环境与饮食，活动和体重之间的关系会因缺乏有效和可靠的评估工具而受到损害。拟议的宅基地工具将解决这一差距，并有助于阐明家庭和儿童肥胖与计划干预措施之间的关系。
