About

The objective of this project was to evaluate a population-based, computerized tailored intervention that addresses recommended guidelines for three target behaviors related to obesity risk: physical activity (at least 60 minutes on at least 5 days per week), fruit and vegetable consumption (at least 5 servings of fruits and vegetables each day), and limited TV viewing (2 hours or less of TV each day).

Computerized Tailored Intervention

Experimental group

Description:

Students interacted with the 30-minute program through a series of Transtheoretical Model (TTM) based assessments and tailored feedback messages. A full TTM intervention was delivered for physical activity, in which each of the appropriate constructs of the TTM based on stage of change was addressed. Optimally tailored interventions were delivered for fruit and vegetable consumption and limited TV viewing. These interventions offered feedback on the most important TTM constructs based on stage of change for each behavior. Multimedia components, including audio, video, and animations helped to capture students' interest.

Treatment:

Behavioral: Health in Motion

Control

No Intervention group

Description:

Computerized assessments of Transtheoretical Model constructs at 0, 2, 6, and 12 months
