Abstract

Objective

To examine the effectiveness of three modalities for delivery of nutrition education.

Design

Between-subjects, repeated-measures design.

Setting

Data were collected at community agencies or during home visits.

Participants

Low-income, European American and African American mothers (N = 155).

Intervention

Participants were exposed to nutrition education material in 1 of 3 modalities (a computer game, The Fantastic Food Challenge; Web site; or pamphlet). Likeability, nutrition knowledge, intention to use, and demographic measures followed the intervention at T1 and T2.

Main Outcome Measures

5-point Likert-type scales measured likeability (5 items), and 33 multiple-choice questions measured knowledge.

Analysis

Data were analyzed using analysis of variance (ANOVA) and analysis of covariance (ANCOVA) procedures using SPSS version 15.0 (SPSS Inc., Chicago, IL) software, P < .05.

Results

Overall, the Web site was liked more than the other conditions with this audience of women. Significant differences in attention, understanding, and intent to use the information existed across modalities. The Web site performed better than other modalities on knowledge outcomes, with no differences in knowledge retention from T1 toT2.

Conclusions and Implications

The Web site modality performed best with this audience of women, indicating that interactive computer games may not confer greater benefits than traditional modes of information delivery for all audiences, particularly those with low computer skills.
