项目摘要

DESCRIPTION (provided by applicant): In response to Program Announcement 04-147 inviting the submission of applications that address developmental research in cancer prevention, the proposed research will examine the predictive utility of a model for understanding adherence to a low-fat diet in economically disadvantaged Black adolescents. Measures for assessing behaviors related to selecting a low-fat diet and motivational readiness to adopt these behaviors among economically disadvantaged African American adolescents aged 11 through 14 years will be developed. Initial item pools for the planned measures will be written. Item pools will undergo review by an expert panel and sample of 40 representatives of the target population and will be revised based on feedback from these referents. The scales will be administered to a sample of 300 economically disadvantaged Black adolescents. The measurement structure, internal consistency reliability, and criterion validity of scales for measuring behaviors related to selecting a low-fat diet and the sensitivity, specificity, and predictive value of algorithms for classifying respondents according to their motivational readiness to adopt these behaviors will be examined. Data provided by youths will inform understanding of fat-reduction behaviors that have salience for the target population and examine whether representatives of this population vary in their readiness to adopt the behaviors identified. Hierarchical linear modeling will examine the predictive utility of the proposed model of adolescent fat intake. Should the proposed model predict fat intake at a level higher than that reflected in the literature on models for predicting this behavior, findings from the research will advance understanding of low-fat eating in African American adolescents. Findings will provide data on which to base interventions to promote low-fat eating in this population.

描述(由申请人提供)：作为对计划公告04-147邀请提交涉及癌症预防发展研究的申请的响应，拟议的研究将检验一个模型的预测效用，以了解经济困难的黑人青少年遵守低脂肪饮食的情况。将制定措施，评估与选择低脂饮食有关的行为，以及在11至14岁的经济困难的非裔美国青少年中采取这些行为的动机准备情况。将编写计划措施的初始项目库。项目库将由一个专家小组和目标人口的40名代表组成的样本进行审查，并将根据这些推荐人的反馈进行修订。这些量表将对300名经济困难的黑人青少年进行抽样调查。将检验用于测量与选择低脂饮食相关的行为的量表的测量结构、内部一致性可靠性和标准效度，以及根据受访者采用这些行为的动机准备程度对他们进行分类的算法的敏感性、特异性和预测价值。年轻人提供的数据将有助于了解对目标人群具有显著意义的减脂行为，并检查这些人群的代表在采取已确定的行为方面是否存在差异。分层线性模型将检验所提出的青少年脂肪摄入量模型的预测效用。如果建议的模型预测脂肪摄入量的水平高于预测这种行为的模型文献中反映的水平，研究结果将促进对非裔美国青少年低脂肪饮食的理解。研究结果将提供数据，作为在这一人群中促进低脂肪饮食的干预措施的基础。
