Data Collection
RA
There were 3 data collection time points in this study: preintervention (T1), immediately post intervention at 3 months (T2), and 3 months post intervention (T3). This was to identify how many participants in the mHealth+I and mHealth groups were still using the mHealth app at the 6-month point, and to evaluate the sustained effects of the intervention. A trained RA not involved in the interventions collected the data in the 5 community centers.
