This article describes the development and randomized evaluation of a tailored nutrition education CD-ROM program for participants in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) in North Carolina.
After randomization to intervention or control groups, participants completed a baseline survey and were resurveyed immediately after program use and 1 to 2 months postintervention.
Two WIC clinics in central North Carolina.
A total of 307 respondents to the follow-up survey (response rate 74.8%) comprised the study sample. Participants were female (96%), 20% were pregnant, and 50% were minorities (African American and other).
The interactive CD-ROM consisted of a targeted video soap opera, dietary assessment, and individually tailored dietary feedback and strategies for change.
Measures included total fat and fruit and vegetable intake, knowledge of low-fat and infant feeding choices, self-efficacy, and stages of change.
Descriptive statistics assessed baseline comparability of study groups; analysis of covariance and F tests were used to assess program effects at follow-up.
INTERVENTION group members increased self-efficacy (P <.01) and scored significantly higher (P <.05) on both low-fat and infant feeding knowledge compared with controls. No differential effect was observed for dietary intake variables.
The findings suggest that one dose of an interactive CD-ROM program can impact mediators of dietary change but may be insufficient to change behavior.
本文描述了为北卡罗来纳州妇女、婴儿和儿童特别补充营养计划（WIC）的参与者开发并进行随机评估的定制营养教育光盘项目。
在随机分为干预组或对照组后，参与者完成基线调查，并在使用项目后立即以及干预后1至2个月再次接受调查。
北卡罗来纳州中部的两家WIC诊所。
共有307名随访调查的受访者（回复率74.8%）构成研究样本。参与者均为女性（96%），20%为孕妇，50%为少数族裔（非裔美国人和其他族裔）。
交互式光盘包括有针对性的视频肥皂剧、饮食评估以及个性化的饮食反馈和改变策略。
指标包括总脂肪、水果和蔬菜摄入量、低脂和婴儿喂养选择知识、自我效能感以及改变阶段。
描述性统计评估研究组的基线可比性；协方差分析和F检验用于评估随访时的项目效果。
与对照组相比，干预组成员的自我效能感有所提高（P<.01），在低脂和婴儿喂养知识方面得分显著更高（P<.05）。在饮食摄入变量方面未观察到差异效应。
研究结果表明，一剂交互式光盘项目可以影响饮食改变的中介因素，但可能不足以改变行为。
