SCHOOL COMPUTER PROGRAMS FOR TEENS FOR SIX CANCER RISKS

项目描述（摘自申请人摘要）：本项目申请 认知在学校与青少年有四个主要目标：1）复制 在学校积极主动的青少年中发现了极好的结果， 吸烟、高脂饮食 饮食和阳光照射2)将这些发现扩展到三个额外的 癌症的行为风险因素，即酗酒，久坐的生活方式 和压力;以及3）加强我们目前的吸烟，饮食和 通过创建一个综合的专家系统，教青少年 改变这些和其他风险行为的基本原则和过程; 4） 探索在学校和他们的学生治疗的累加效应， 在家中的父母（在名为“家庭计算机”的并行交互式RO 1项目中 六种癌症风险因素的父母”）相比， 学生单独为每一个六个目标行为。这个人口为基础的 临床试验采用3 × 4重复测量设计，跨越3组（ 最佳实践专家系统吸烟，饮食和阳光照射;一个创新的 综合专家系统;和新的行为比较组，也 作为分心安慰剂对照。14所高中将参加 3570名九年级学生被随机分配到三组中的一组。所有 与会者将在会议期间接受六次45分钟的专家系统会议， 九年级和十年级专家系统提供规范（与其 同行）和ipsative（与自我相比）的反馈，对每15个相关的 每个相关风险因素的跨理论模型变量。这些 系统旨在提供指导性学习， 通过变革的各个阶段促进进步。由于近80%的 符合条件的学生预计参加，这些计划有相当大的 对六个最重要的国家产生重大人口影响的潜力 癌症和其他慢性疾病的行为风险。该项目将 制作个性化和交互式多媒体计算机程序， 通过学校以具有成本效益的方式传播， 青少年人口。

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.
