This research was conducted to measure the effectiveness of interactive multimedia (IMM) with low-income Hispanic persons.
The effectiveness of the program was examined using a quasi-experimental pretest/post-test control group design.
Subjects were recruited from nutrition, health, and English as a Second Language (ESL) programs in Colorado.
Thirty-six intervention and 34 control participants formed a convenience sample of low-income and predominantly Hispanic persons.
Intervention participants received a 15-minute module about breakfast. Control participants received a non- nutrition-related IMM module.
Primary variables included knowledge, attitude, and stage of change scores.
Paired and independent sample t tests, chi-square analysis, and repeated-measures analysis of covariance (ANCOVA) were used.
Intervention participants significantly increased knowledge, attitude, and total scores (P <.001) between pretest and post-test and had significantly greater increases than the control group (P <.001).
The results support using IMM to disseminate nutrition education to the target population and the feasibility of using computer-based questionnaires to evaluate the effectiveness of IMM nutrition education programs.
This research provides the basis for the continued development of computer-based assessment tools.
本研究旨在评估交互式多媒体（IMM）对低收入西班牙裔人群的效果。
采用准实验性前测/后测对照组设计来检验该项目的效果。
研究对象从科罗拉多州的营养、健康及英语作为第二语言（ESL）项目中招募。
36名干预组参与者和34名对照组参与者构成了一个低收入且主要为西班牙裔人群的便利样本。
干预组参与者接受了一个关于早餐的15分钟模块。对照组参与者接受了一个与营养无关的IMM模块。
主要变量包括知识、态度和行为改变阶段得分。
采用配对和独立样本t检验、卡方分析以及重复测量协方差分析（ANCOVA）。
干预组参与者在前后测之间知识、态度和总分显著提高（P<.001），且比对照组的提高幅度显著更大（P<.001）。
研究结果支持使用IMM向目标人群传播营养教育，以及使用基于计算机的问卷来评估IMM营养教育项目效果的可行性。
本研究为基于计算机的评估工具的持续开发提供了依据。
