Study Design
A quasi-experimental design was used to assess
dietary and physical activity habits of students
in Energize and control groups through 12-week
diet/activity logs and post-test questionnaires after
controlling for the pre-test results. This study contained
3 important methodological features that allowed for
longitudinal data analysis; 3 or more waves of data,
outcomes that change over time, and a metric for
keeping time.13
