01) in mean users per day, pre- to post-intervention, based on the Wilcoxon signed rank test ( Table 4). Table 5 isolates the results
for the signage change period of the study, and it shows that mid- and post-intervention counts decreased for the intervention group, but not for the control group. We found no significant difference between the groups with p = 0.3226 based on the Wilcoxon rank sum test ( Table 6). We found that mean daily users increased overall and on most of the individual trails over the study period. The largest increases in trail traffic were observed shortly after the media campaign at the mid-intervention observation point. While both the study group and the control Selleckchem Regorafenib group experienced increases, the group of trails which received the signage changes were not able to maintain these increases over the second 6-month period. Although usage on the study trails remained higher than baseline at follow-up (35%), the increase observed midway through the intervention was more than twice as high (78%). The control trails experienced a smaller increase at the mid-intervention observation (29%), but trail usage was similar post-intervention (31%) and did not decrease over the second 6-month period. Despite these different patterns this website over
the 1-year observation period, the final post-intervention increase in mean users per day was similar. We used objective measures and a longitudinal study design to assess the effect of a marketing campaign to promote
PA and trail use, as well as an intervention adding way-finding and incremental distance signage to selected trails. The study group experienced a decrease in trail usage from mid- to post-intervention, but overall trail usage increased for both the study and control TCL groups, pre- to post-intervention. Future evaluators may want to consider a different approach to determine if incremental distance signage increases trip length. Since we used one sensor on each trail, we were only able to detect the number of users passing that single point. If a user decided to extend his or her trip length because of the signage, that incremental distance was not reflected in our counts. A study design with multiple ITC sensors on each trail may better detect if incremental distance signage affects patterns of trail use. Intercept surveys with trail users, such as the instrument developed by Troped et al. (2009), could also help clarify changes in PA behavior. This study has several limitations, including the non-random nature of the control trails. When selecting trails for our comparison group, we were limited by the availability of similar local trails, but we attempted to match our study trails on environment, length, amenities, and the demographics of the surrounding neighborhoods.
