Abstract
Objective
Pilot a digital interactive intervention for weight gain prevention among college
students.
Methods
One sample pre-post study reporting on initial usability and changes in theoretical
constructs (ie, self-efficacy, behavioral capability, elaboration) and program acceptability.
Twenty college freshmen (mean age, 18.25 ± 0.72 years) reviewed a digital program
providing self-assessment and brief tailored feedback on 8 behaviors that relate to
a healthy weight: physical activity, sedentary behavior, and consumption of sugary
beverages, high fat snacks, breakfast, fried foods, fruits and vegetables, and pizza.
Results
At posttest, improvements in self-efficacy were found for 5 behaviors (ie, physical
activity, high fat snacks, breakfast, fried foods, fruits and vegetables); improvements
in behavioral capability were found for 3 behaviors (ie, high fat snacks, fried foods,
and fruits and vegetables). Acceptability benchmarks included: positive impression
(60%), relevance (95%), and ease of comprehension (75%).
Conclusions and Implications
This program demonstrates acceptability for a digital weight gain prevention intervention,
with improvements in behavioral mediators of change. Suggestions to simplify messaging
and allowing for user control may enhance acceptability and comprehension. There is
a need for further testing with larger more diverse populations before broader implementation
by universities to address student health.
