This article describes the development and pilot evaluation of a tailored multimedia program to improve dietary behavior among 378 low-income women enrolled in the Food Stamp program in Durham, North Carolina. After randomization to intervention or control groups, participants completed a baseline survey and were resurveyed 1-3 months post-intervention. Measures included dietary fat intake assessed using a brief food-frequency questionnaire, stage of change, knowledge of low-fat foods, self-efficacy and eating behavior questions. The computer-based intervention consisted of a tailored soap opera and interactive 'info-mercials' that provided individualized feedback about dietary fat intake, knowledge and strategies for lowering fat based on stage of change. At follow-up, intervention group participants had improved significantly in knowledge (P < 0.001), stage of change (P < 0.05) and certain eating behaviors (P < 0.05) compared to the control group. Both study groups had lowered their reported fat intake markedly at follow-up (P < 0.001), but did not differ significantly from each other. A majority of participants rated the program as very helpful and were interested in using a similar program in the future. The findings of this pilot study suggest that computerized tailored self-help health promotion programs may be effective educational interventions for lower income and minority populations.
