Assessing African American Adolescent Food Intakes

描述（由研究者提供）：这项修订后的I期可行性研究将开发和测试一种计算机介导的食物记录，用于测量11至14岁的城市、经济困难的非裔美国青少年的水果和蔬菜消费量。在纽约市八个社区地点与参加社会服务方案的48名青年进行的重点小组讨论将为制定该措施的原型提供信息。该措施的表现将在一个重复的措施设计与一个单独的样本60名青年从合作网站进行检查。 每组15名青年将在四个星期六中的一个星期六连续提供三餐。饭后，青少年将使用预装软件的电脑记录他们的水果和蔬菜摄入量。将通过目视估计方法使用盘子废物记录实际摄入量，并在用餐期间不引人注目地记录录像数据。收集的数据将用于确定标准相关的有效性和重测信度的措施。如果第一阶段取得成功，将继续提供第二阶段的支助，以充分制定和测试这一措施。第三阶段将向社区机构传播，用于旨在增加目标人群水果和蔬菜消费的健康促进方案。

DESCRIPTION (provided by investigator): This revised Phase I feasibility study will develop and test a computer-mediated food record for measuring fruit and vegetable consumption among urban, economically disadvantaged, African American adolescents, aged 11 through 14 years. Focus groups conducted with 48 youths enrolled in social service programs across eight community-based sites in New York City will inform the development of a prototype version of the measure. The performance of the measure will be examined in a repeated measures design with a separate sample of 60 youths from collaborating sites. Groups of 15 youths each will be provided three consecutive meals on one of four Saturdays. Following meals, youths will record their fruit and vegetable intakes using computers on which the software has been preinstalled. Actual intake will be recorded using the plate waste by visual estimate method and videotaped data unobtrusively recorded during meals. Data gathered will be used to determine the criterion-related validity and test-retest reliability of the measure. If Phase I is successful, Phase II support will be pursued to fully develop and test the measure. Phase III will entail its dissemination to community-based agencies for use in health promotion programs intended to increase fruit and vegetable consumption among the target population.
