Summary
Computer-tailored interventions effectively boost physical activity and reduce fat intake. Both sequential and simultaneous delivery methods work, with simultaneous being slightly better for fat intake and physical activity adherence.
Area of Science:
- Behavioral Science
- Health Informatics
- Public Health Interventions
Background:
- Limited evidence on interactive computer-tailored interventions for physical activity and diet.
- Uncertainty regarding the combined effectiveness and optimal delivery (sequential vs. simultaneous) of tailored interventions.
Purpose of the Study:
- Evaluate interactive computer-tailored interventions for increasing physical activity and decreasing fat intake.
- Determine the most effective delivery mode (sequential or simultaneous) for behavior change.
Main Methods:
- Randomly assigned 771 participants into four groups: simultaneous intervention, sequential interventions (two orders), and a control group.
- Interventions focused on physical activity and fat intake, delivered at baseline and/or 3 months postbaseline.
- Assessed outcomes six months postbaseline.
Main Results:
- Tailored interventions significantly increased physical activity and decreased fat intake compared to the control group.
- Both sequential and simultaneous delivery modes demonstrated effectiveness for both behaviors.
- Simultaneous delivery showed a potential advantage for fat intake and for participants struggling with physical activity recommendations.
Conclusions:
- Interactive computer-tailored interventions are effective for improving physical activity and dietary fat intake.
- Both sequential and simultaneous delivery strategies are viable, with simultaneous delivery potentially offering benefits for specific behaviors and participant groups.
