Cancer Risk Reduction through Dietary Intervention

描述（由申请人提供）：这个第二阶段的SBIR将开发和测试一个基于理论的、适合发展的、文化特定的干预措施，旨在促进经济上处于不利地位的11至14岁的黑人早期青少年增加水果和蔬菜的消费。根据饮食行为改变的理论和实证文献以及第一阶段的数据，第二阶段将起草干预内容。形成性评估程序将确保干预内容在文化和发展上适合目标人群。干预措施将由一个专家小组进行连续审查；一个由社区专业人士组成的小组，他们有帮助经济上处于不利地位的黑人青年的经验；样本是48个代表目标人群的年轻人。将根据这些参照者提供的反馈对干预措施进行修订，并将对干预措施进行编程，以便通过cd - rom提供。相对于无干预，cd - rom介导干预的有效性将在随机受试者前测后测对照组设计中进行检验。

DESCRIPTION (provided by applicant): This Phase II SBIR will develop and test a theory based, developmentally appropriate, and culturally specific intervention designed to promote increased fruit and vegetable consumption among economically disadvantaged Black early adolescents aged 11 through 14 years. Drawing from the theoretical and empirical dietary behavior change literature and Phase I data, Phase II will draft intervention content. Formative evaluation procedures will ensure that intervention content is culturally and developmentally appropriate for the target population. The intervention will undergo successive reviews by an expert panel; a panel of community-based professionals that have experience working with economically disadvantaged Black youths; and a sample of 48 youths representative of the target population. Revisions will be made to the intervention based on feedback provided by these referents, and the intervention will be programmed for CD-ROM-mediated delivery. The efficacy of the CD-ROM-mediated intervention, relative to no intervention, will be examined in a randomized-subjects pretest-posttest control group design. Recruited through youth services agencies across greater New York City, 974 informed and consenting youths will be randomized to experimental and control study arms. Experimental arm youths will interact with the software in four on-site sessions delivered over an eight-month period. Youths will complete outcome measurement batteries before and after intervention. Outcome analyses will determine the efficacy of the computer-mediated intervention in increasing youth's fruit and vegetable consumption and promoting forward movement through the stages of change for fruit and vegetable consumption. Should the CD-ROM intervention prove effective, it will be disseminated to schools and youth services agencies similar to those engaged in this research and development effort through direct marketing efforts and through licensing agreements with distributors of youth-oriented health promotion programs.
