Sustained Effectiveness of the Walk Across Texas Program: A Follow-up Study

Abstract

Objectives: In this study, we used a follow-up assessment to determine the sustained effectiveness of Walk Across Texas, a web-based community physical activity program. Methods: We recruited a sample of adult participants (N=291) who completed program assessments across 3 time periods (pre-, post-, follow-up) in 2018. We assessed changes in self-reported physical activity (days/week). Statistical analysis incorporated paired-samples t-tests, repeated measures ANOVA, and an assessment of participants' overall physical activity changes during the program and follow-up. Results: Overall, there were statistically significant differences (p < .05) between self-reported physical activity pre-program (4.12 ± 2.10), post-program (5.06 ± 2.04), and at follow-up (4.40 ± 1.98). Notably, a defined Low Active pre-program activity group significantly increased from pre- (1.21 ± 0.87) to post-program (4.29 ± 2.06). Despite a decrease from post-program to follow-up (3.06 ± 1.86; δ = -1.24 days), the difference remained higher and statistically significant from pre-program. Further analysis explored limitations associated with estimating one's physical activity change in behavior. Conclusions: The results support the sustained effectiveness of the Walk Across Texas program. Overall, participants showed increased and maintained physical activity for up to 150 days from pre-program.
