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.

描述（由申请人提供）：此第二阶段SBIR将开发和测试一个基于理论的，发展适当的，和文化特定的干预措施，旨在促进增加水果和蔬菜的消费在经济上处于不利地位的黑人早期青少年11至14岁。从理论和经验饮食行为改变文献和第一阶段的数据，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方面适合目标人群。干预措施将由一个专家小组、一个具有与经济上处于不利地位的黑人青年打交道经验的社区专业人员小组以及代表目标人口的48名青年抽样进行连续审查。将根据这些参考提供的反馈对干预措施进行修订，并将干预措施编程为光盘介导的交付。CD-ROM介导的干预的有效性，相对于没有干预，将在一个随机的受试者的前测-后测控制组设计。 通过大纽约市的青年服务机构招募，974名知情同意的青年将被随机分配到实验组和对照组。实验组的年轻人将在为期八个月的四次现场会议上与该软件进行互动。青少年将在干预前后完成结果测量。结果分析将确定计算机介导的干预措施在增加青年水果和蔬菜消费和促进水果和蔬菜消费变化阶段向前发展方面的效力。如果光盘干预证明是有效的，将通过直接销售努力和通过与面向青年的健康促进方案的经销商签订的许可协议，向类似于从事这项研究和发展工作的学校和青年服务机构分发。
