INTERACTIVE VIDEODISC INTERVENTION TO REDUCE CHD

该项目将制作和评估基于互动视盘的 (IVD)系统旨在降低中国患冠心病的风险 工作场所通过改变员工的饮食行为。互动系统 将根据用户的特征“定制”干预演示文稿。 使用由用户提供的饮食和人口统计信息，该系统 选择干预内容和屏幕模式(使用AGE 种族/民族和性别)基于用户的特征和先前 程序的使用。 在该项目的第一阶段，我们将：(A)使用形成性评价程序 确定视盘干预的适当内容(B) 制作逻辑流程图和随时可用的脚本，以满足 某一特定亚群(即老年高加索人)的特征 男性)(C)为该小组制作适当的视频片段和旁白- 人口(D)制作计算机程序以控制呈现 基于用户特征的视盘素材。(E)组装 一个功能齐全的售货亭。和(F)评估该方案的效果 采用基于理性行动理论的前测设计。 在第二阶段，我们会：(A)完成第一阶段的发展程序 剩余的子种群(B)产生完整的独立信息亭， 适合在工作场所使用，以及(C)评估 程序。

This project will produce and evaluate an interactive videodisc-based (IVD) system designed to reduce coronary heart disease risk in the worksite by modifying employee dietary behavior. The interactive system will "tailor" the intervention presentation to the user's characteristics. Using dietary and demographic information provided by the user, the system selects intervention content and on-screen models (using aged race/ethnicity and gender) based on the user's characteristics and prior use of the program. In Phase I of the project we will: (a) use formative evaluation procedures to determine the appropriate content of the videodisc intervention (b) produce logic flowcharts and ready-to-shoot scripts tailored to the characteristics of one specific sub-population (i.e., older Caucasian males) (c) produce appropriate video segments and narration for that sub- population (d) produce a computer program to control the presentation of the videodisc material based on the user's characteristics. (e) assemble a fully functional kiosk. and (f) evaluate the efficacy of the program using a pre-post test design based on the Theory of Reasoned Action. In Phase II we will: (a) complete the Phase I development process for the remaining subpopulations (b) produce a complete stand-alone kiosk, suitable for use in worksites, and (c) evaluate the efficacy of the program.
