DESCRIPTION (provided by applicant): 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.

描述（由申请人提供）：目标：开发特定于超重青年的多元文化生活质量（QOL）仪器，用于评估体重管理治疗和调查环境和社会心理协会。目的：1）使用深入的访谈和与非裔美国人，高加索人和墨西哥裔美国人在华盛顿西部和南加州的11-18岁的非洲裔美国人，高加索人和墨西哥裔美国人青年一起开发美国英语和墨西哥裔美国人西班牙语的特定体重QOL乐器； 2）使用经典的心理测量学和IRT分析来验证新的体重特定仪器的横断面心理测量和实际测量特性； 3）探索BMI与QOL和已知或假设的相关性的关联，4）评估项目和措施的能力，检测一小部分年轻人参加并不参加正式减肥计划的变化，而5）产生/散布该乐器的最终版本。意义：近年来，高加索青年的超重状况增加了两倍，只有少数族裔青年（主要是墨西哥裔美国人和非裔美国人）的三倍增长才掩盖了。少数族裔青年超重的这种不成比例的增长可能会加剧预先存在的健康结果差异，并需要创新的方法来理解其观点，并设计和评估有效的治疗方法，以减少健康差异。创新：应通过针对体重治疗的主要受影响的文化群体的全面参与制定QOL措施。在这项研究中，与多元文化研究者的不同种族的措施的同时文化发展将满足这一要求。方法和分析：以定性方法为基础的全面概念模型将推动测量开发。深入的访谈和具有120个超重和高危青年的焦点小组将采用基于需求的模型和对文化敏感的方法来进行仪器开发。将进行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。将招募360名青年的验证样本（200 BMI 2> 95％，80 BMI 85-94％； 80 BMI Z 84％）将被招募，他们将完成新的特定体重特定仪器和其他问卷。因子分析和项目响应方法将用于规模开发。将检查可靠性，结构有效性，效应大小的评估，并将检查与BMI的关联。估计功率在77-99％之间，用于检测差异，使用单变量和多变量建模，以调查已知和假设的相关性，其效应大小为.41或更大。研究人员：经验丰富的成果专家，肥胖专家，内分泌学家和社区代理商的多元文化团队将合作招募，学习，出版和传播结果。
