Participant milestones
| Measure |
Enhanced Physical Activity Intervention
A data driven enhanced Pasos Hacia La Salud intervention based on results and participant feedback from the motivationally-tailored, Spanish Language, Internet-based Physical Activity intervention in the parent study.
|
Original Physical Activity Intervention
The original Internet-based program is a computer expert system-driven, individually tailored Spanish language intervention, guided by Social Cognitive Theory (SCT) and the Transtheoretical Model (TTM).
