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）：第二阶段 SBIR 将开发和测试基于理论、适合发育且针对特定文化的干预措施，旨在促进 11 至 14 岁经济弱势黑人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。该干预措施将接受专家小组的连续审查；由具有与经济弱势黑人青年合作的经验的社区专业人士组成的小组；以及代表目标人群的 48 名青少年样本。将根据这些参考者提供的反馈对干预进行修改，并且干预将被编程为 CD-ROM 介导的传递。 CD-ROM 介导的干预相对于无干预的功效，将在随机受试者前测试后测试对照组设计中进行检查。 通过大纽约市的青年服务机构招募的 974 名知情且同意的青年将被随机分配到实验组和对照研究组。实验手臂青年将在八个月的时间内通过四次现场会议与该软件进行互动。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少年水果和蔬菜消费以及促进水果和蔬菜消费变革阶段向前发展方面的有效性。如果 CD-ROM 干预措施被证明是有效的，它将通过直接营销工作以及通过与面向青年的健康促进计划的经销商签订许可协议，向学校和类似于从事这项研究和开发工作的青年服务机构分发。
