DESCRIPTION (provided by applicant): We are sedentary for the majority of our waking hours (e.g., reclining, sitting still) and time spent in these behaviors have been independently associated with reduced energy expenditure, increased risk for weight gain, and chronic disease. The efforts of researchers and health care providers interested in sedentary behavior (SB) would be greatly enhanced by a valid and easy- to-administer instrument for population-based studies that can assess SBs in terms of their context, setting, purpose, type, and amount. Such an instrument would reveal more fully the impact of SBs on health, and would allow a measurement of changes in behaviors in response to interventions. Our overall goal is to develop an instrument of manageable length that provides a comprehensive profile of major SBs in the population, and that produces a heterogeneous measure of these behaviors. We propose a research program to be conducted in two populations (adolescents and adults) at risk for the adverse health consequences of sedentarism. First, we will describe carefully the most important SBs in terms of the prevalence and duration using available national data sources and information from a de novo descriptive study (N=200). We will use these descriptive studies to develop and refine in parallel three SB questionnaires: two age-specific instruments (adolescents, adults) and a common measure that may be suitable for both age-groups. We will determine the feasibility of the common measure using results from our descriptive studies, cognitive testing, and expert review. If it is feasible we will evaluate it in the second portion of our research. If not, we will evaluate the age-specific instruments. Second, we will conduct a reliability and validity study of the new SBQ(s) in a separate sample of adolescents (n=200) and adults (n=200) using both self-report and objective measures to establish criterion validity. In addition to evaluating the psychometric properties of the SBQs via factor analysis, we also will conduct exploratory analyses to identify a subset of items that could be used as a short-form of the instrument(s). Third, we will disseminate the new SBQs and their scoring algorithms for free via the web. We anticipate that the instruments developed in this research program will facilitate studies that attempt to describe where and why SBs occur, etiologic studies that examine the adverse effects of SBs on health, and clinical and intervention studies that seek to quantify changes in these behaviors in response to an intervention or health promotion program. PUBLIC HEALTH RELEVANCE: We are sedentary for the majority of our waking hours and time spent in these behaviors has been associated with obesity and chronic disease. The efforts of researchers and health care providers interested in sedentary behavior (SB) would be enhanced greatly by the existence of a valid and easy-to-administer instrument with which to measure SB. We seek to develop a questionnaire of manageable length that comprehensively assesses major SBs in the population. Inclusion of Women Plan: One-half of targeted and planned enrollment includes women. Inclusion of Minorities Plan: The targeted and planned enrollment includes representation of minorities that is consistent with the geographic location. Inclusion of Children Plan: The study will recruit an equal number of children (ages 12-17) as adults.

描述（由申请人提供）：我们在大部分醒来的时间（例如，躺着，坐着静止）久坐着，这些行为花费的时间与能量消耗减少，体重增加的风险增加和慢性病是独立的。有效且易于易于待办事项的研究人员将大大提高对久坐行为（SB）感兴趣的研究人员和卫生保健提供者的努力，用于基于人群的研究，可以根据其上下文，设置，目的，类型和数量评估SBS。这样的工具将更充分地揭示SB对健康的影响，并可以衡量行为变化以响应干预措施。我们的总体目标是开发一种易于管理的工具，该工具在人群中提供了主要SB的全面概况，并产生对这些行为的异质度量。我们建议在两个人群（青少年和成年人）中进行一项研究计划，面临久坐不良后果的风险。首先，我们将使用可用的国家数据源和从头描述性研究（n = 200）中的可用国家数据源和信息仔细描述最重要的SB。我们将使用这些描述性研究在平行的三个SB问卷中开发和完善：两种特定年龄的仪器（青少年，成人）和一种可能适合两个年龄组的常见措施。我们将使用我们的描述性研究，认知测试和专家审查的结果来确定共同度量的可行性。如果可行，我们将在研究的第二部分中对其进行评估。如果没有，我们将评估特定年龄的乐器。其次，我们将在单独的青少年样本（n = 200）和成人（n = 200）中使用自我报告和客观措施来建立标准有效性。除了通过因子分析评估SBQ的心理测量特性外，我们还将进行探索性分析，以确定可以用作仪器短形式的项目的子集。第三，我们将通过网络免费传播新的SBQ及其评分算法。我们预计，本研究计划中开发的工具将促进试图描述SB的何处和为什么发生的研究，这些研究研究SBS对健康的不利影响以及临床和干预研究，这些研究旨在响应干预措施或健康促进计划来量化这些行为的变化。公共卫生相关性：我们在这些行为上花费的大部分时间和时间都久坐着与肥胖和慢性病有关。对久坐行为（SB）感兴趣的研究人员和医疗保健提供者的努力将通过有效且易于使用的工具来大大提高，以测量SB。我们试图制定可管理长度的问卷调查，以全面评估人群中的主要SB。 包括妇女计划：有针对性和计划的入学人数包括妇女。 包括少数民族计划：目标和计划的入学人数包括与地理位置一致的少数民族的代表。 包括儿童计划：该研究将招募与成年人相同数量的儿童（12-17岁）。
