项目摘要

DESCRIPTION (provided by applicant): This Phase I study will develop and test a questionnaire to measure fruit and vegetable consumption, demographic data, and variables based on constructs from the transtheoretical model of behavior change among economically disadvantaged Black adolescents 11 through 14 years of age. Focus groups with 64 youths will gather data on the relevance and exhaustiveness of items. Content validity will be assessed by subjecting the instrument to expert review. Pilot testing will be carried out with a separate sample of 40 youths who will rate the clarity, interpretability, relevance, order, layout and exhaustiveness of items. Exploratory factor analysis and internal consistency reliability analyses will be performed to confirm the measurement structure and internal consistency of questionnaire subscales. Cross-sectional data from a separate sample of 250 youths will be used to confirm relationships predicted by the model and examine associations between transtheoretical variables, demographic data, and fruit and vegetable consumption. Those data will inform Phase II efforts to develop an intervention based on the model. The efficacy of the intervention will be examined in a randomized clinical trial. Should Phase II prove successful, Phase III will entail its dissemination to community-based agencies similar to those engaged in this R & D project.

描述（由申请人提供）：这项I期研究将开发和测试一份问卷，以衡量水果和蔬菜的消费，人口统计数据和变量的基础上，从经济上处于不利地位的黑人青少年11至14岁的行为变化的跨理论模型的结构。由64名青年组成的焦点小组将收集关于项目的相关性和详尽性的数据。将通过对仪器进行专家审查来评估内容有效性。将对40名年轻人进行单独的试点测试，他们将对项目的清晰度、可解释性、相关性、顺序、布局和详尽性进行评级。将进行探索性因素分析和内部一致性信度分析，以确定问卷子量表的测量结构和内部一致性。来自250名年轻人的单独样本的横截面数据将用于确认模型预测的关系，并检查跨理论变量，人口统计数据和水果和蔬菜消费之间的关联。这些数据将为第二阶段的工作提供信息，以根据该模型制定干预措施。干预的有效性将在随机临床试验中进行检查。如果第二阶段取得成功，第三阶段将向类似于参与这一研究与发展项目的社区机构传播。
