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II期SBIR将开发和测试一种基于理论，适当和具有文化特定的干预措施，旨在促进经济不利的黑人早期青少年11至14岁的经济不利的黑人早期青少年。从理论和经验性饮食行为变化文献和I期数据中，第二阶段将起草干预含量。形成性评估程序将确保干预含量在文化和发展上适合目标人群。干预将由专家小组的连续评论进行；由社区专业人士组成的小组，具有与经济不利的黑人青年合作的经验；以及48名代表目标人群的年轻人的样本。将根据这些指南提供的反馈对干预进行修订，并将对干预进行编程以进行CD-ROM介导的交付。相对于无干预措施，CD-ROM介导的干预措施的功效将在随机受试者的预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，有974名知情和同意的年轻人将被随机分为实验和对照研究武器。实验性的ARM青年将在八个月内进行的四个现场会议中与该软件进行互动。年轻人将在干预前后完成结果测量电池。结果分析将确定计算机介导的干预措施在增加青少年的水果和蔬菜消费方面的功效，并通过变化的阶段来促进前进的效果。如果CD-ROM干预被证明有效，则将通过直接营销工作以及与面向青年健康促进计划的分销商达成许可协议，将其传播给学校和青年服务机构。
