Goal: To develop a multicultural quality of life (QoL) instrument specific to overweight youth for use in evaluating weight-management treatments and investigating environmental and psychosocial associations. Aims: 1) To develop a weight-specific QoL instrument in US English and Mexican-American Spanish using in-depth interviews and focus groups with African-American, Caucasian, and Mexican-American youth ages 11-18 in Western Washington and Southern California; 2) To validate cross-sectional psychometric and practical measurement properties of the new weight-specific instrument using classical psychometric and IRT analyses; 3) To explore associations of BMI with QoL and known or hypothesized correlates, 4) To assess the ability of the items and measures to detect change in a small cohort of youth participating and not participating in a formal weight loss program, and 5) To produce/disseminate final version of the instrument. Significance: The two-fold increase in overweight status among Caucasian youth in recent years is only overshadowed by the three-fold increases among minority youth, primarily Mexican-Americans and African- Americans. This disproportionate increase in overweight among minority youth may exacerbate pre-existing health outcome disparities and require innovative approaches to understanding their perspectives and to design and evaluate effective treatments that will reduce health disparities. Innovation: A QoL measure should be developed with full participation of the major affected cultural groups targeted for weight treatment. Simultaneous cultural development of measures in different ethnic groups with multicultural investigators in this study will meet this requirement. Methods and Analysis: A comprehensive conceptual model grounded in qualitative methodology will drive measurement development. In-depth interviews and focus groups with 120 overweight and at-risk youth will apply a needs-based model and culturally sensitive approach to instrument development. Generation of items in English and Spanish and cognitive debriefing, readability, and translatability analyses will be conducted. A validation sample of 360 youth (200 BMI 2> 95%, 80 BMI 85-94%; 80 BMI z 84%) will be recruited who will complete the new weight-specific instrument and other questionnaires. Factor analysis and item-response methods will be used for scale development. Evaluation of reliability, construct validity, effect sizes in a small cohort, and association with BMI will be examined. Power is estimated to be between 77-99% to detect differences with an effect size of .41 or greater using univariate and multivariate modeling to investigate known and hypothesized correlates. Investigators: Multicultural team of experienced outcomes experts, obesity experts, endocrinologists, and community agents will collaborate to recruit, study, publish, and disseminate results.

目标：开发特定于超重青年的多元文化生活质量（QOL）仪器 评估体重管理治疗并研究环境和社会心理关联。 目的：1）使用美国英语和墨西哥裔美国人西班牙语开发特定体重的QOL乐器 与非裔美国人，高加索人和墨西哥裔美国人年龄的深入访谈和焦点小组 华盛顿西部和南加州11-18； 2）验证横断面心理测量学和 使用经典心理测量学和 IRT分析； 3）探索BMI与QOL和已知或假设相关的关联，4） 评估项目和措施检测一小部分青年队列的变化的能力，而不是 参加正式的减肥计划，以及5）制作/传播该乐器的最终版本。 意义：近年来高加索青年的超重状况增加了两倍 少数族裔青年（主要是墨西哥裔美国人和非洲人）的三倍增长所掩盖 美国人。少数族裔青年超重的这种不成比例的增长可能会加剧现有的 健康结果差异，需要创新的方法来理解其观点和 设计和评估将减少健康差异的有效治疗方法。 创新：应在主要受影响的文化群体的充分参与下制定QOL措施 针对体重处理。同时在不同种族的措施的文化发展 随着多元文化研究人员，这项研究将满足这一要求。 方法和分析：以定性方法为基础的全面概念模型将驱动 测量开发。深入的访谈和焦点小组与120个超重和高风险的青年将 在仪器开发中应用基于需求的模型和对文化敏感的方法。产生 英语和西班牙语的项目以及认知汇报，可读性和可翻译性分析将是 实施。 360名青年的验证样本（200 BMI 2> 95％，80 BMI 85-94％； 80 BMI Z 84％）为 招募将完成新的特定体重仪器和其他问卷调查的人。因子分析 项目响应方法将用于规模开发。评估可靠性，构造有效性， 小队列中的效应大小，将检查与BMI的关联。电源估计在 77-99％使用单变量和多变量建模，以0.41或更大的效果大小检测差异 研究已知和假设的相关性。 调查人员：经验丰富的成果专家，肥胖专家，内分泌学家和多元文化团队 社区代理人将合作招募，学习，出版和传播结果。
