SCHOOL COMPUTER PROGRAMS FOR TEENS FOR SIX CANCER RISKS

描述(改编自申请人摘要)：本项目申请 有青少年的学校的认知有四个主要目标：1)复制 在那些在学校积极接受教育的青少年中，发现了出色的结果， 个性化、交互式的吸烟、高脂肪多媒体专家系统 饮食和阳光暴晒。2)将这些调查结果扩展到另外三个 癌症的行为危险因素，即酗酒、久坐不动的生活方式 和压力；以及3)加强我们目前吸烟、饮食和 通过创建一个集成的专家系统，向青少年传授 改变这些和其他危险行为的基本原则和程序；4) 探索在学校治疗学生和他们的学生的相加效应 在家的父母(在一个名为“家用计算机”的平行互动RO1项目中 对于患有六种癌症风险因素的父母来说“)与只治疗 对于六种目标行为中的每一种，学生都是单独的。这是基于人口的 临床试验采用3×4重复测量设计，跨越3组( 吸烟、饮食和阳光暴晒的最佳实践专家系统；创新的 集成的专家系统；和新行为对照小组，也 作为一种分散注意力的安慰剂对照。将有14所高中参加 3570名九年级学生被随机分配到三组中的一组。全 参与者将在以下时间内收到六次45分钟的专家系统会议 九年级和十年级。专家系统提供了规范性(与其 同事)和(与自己相比)对15个相关的 每一个相关风险因素的跨理论模型变量。这些 系统旨在提供指导学习，以加速和 在变革的各个阶段促进进步。因为近80%的 符合条件的学生预计将参加，这些项目有相当大的 可能对六个最重要的人口产生重大影响 癌症和其他慢性病的行为风险。该项目将 制作个性化和交互式的多媒体计算机程序，可以 通过学校以具有成本效益的方式传播，帮助 青少年群体。

DESCRIPTION (Adapted from the Applicant's Abstract): This project applying cognitives in schools with adolescents has four primary aims: 1) to replicate the excellent results found with adolescents who received at school proactive, individualized and interactive multimedia expert systems for smoking, high fat diets and sun exposure. 2) To expand these findings to three additional behavioral risk factors for cancer, namely alcohol abuse, sedentary life-styles and stress; and 3) to enhance our current best practices for smoking, diet and sun exposure by creating an integrated expert system that teaches teenagers the basic principles and processes for changing these and other risk behaviors; 4) to explore the additive effects of treating both students at school and their parents at home (in a parallel Interactive RO1 project entitled "Home Computers for Parents for Six Cancer Risk Factors") compared to treating just the students alone for each of the six target behaviors. This population-based clinical trial employs a 3 X 4 repeated measures design crossing 3 groups (the Best Practices expert systems for smoking, diet and sun exposure; an innovative integrated expert system; and the New Behaviors comparison group that also serves as a distraction placebo control. Fourteen high schools will participate with 3570 ninth graders being randomly assigned to one of the three groups. All participants will receive six 45 minute expert system sessions during their ninth and tenth grades. The expert systems provide normative (compared to their peers) and ipsative (compared to self) feedback on each of the 15 relevant Transtheoretical Model variables for each of their relevant risk factors. These systems are designed to provide guided learning for accelerating and facilitating progress through stages of change. Since nearly 80 percent of eligible students are expected to participate, these programs have considerable potential to produce major population impacts on six of the most important behavioral risks for cancer and other chronic diseases. The project will produce individualized and interactive multimedia computer programs that can be disseminated in a cost-effective manner through schools to help entire populations of adolescents.
