Objective:
This research was conducted to measure the effectiveness of interactive multimedia (IMM) with low-income Hispanic persons.
Design:
The effectiveness of the program was examined using a quasi-experimental pretest/post-test control group design.
Setting:
Subjects were recruited from nutrition, health, and English as a Second Language (ESL) programs in Colorado.
Participants:
Thirty-six intervention and 34 control participants formed a convenience sample of low-income and predominantly Hispanic persons.
Intervention:
Intervention participants received a 15-minute module about breakfast. Control participants received a non- nutrition-related IMM module.
Main Outcome Measures:
Primary variables included knowledge, attitude, and stage of change scores.
Analysis:
Paired and independent sample t tests, chi-square analysis, and repeated-measures analysis of covariance (ANCOVA) were used.
Results:
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).
Conclusions:
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.
Implications:
This research provides the basis for the continued development of computer-based assessment tools.
