Measures
RECRUITMENT
The measures used are summarized briefly. For more details about specific question wording used in the measures and items, please refer to the paper by Gans et al [Primary study outcomes were feasibility and acceptability. Although we measured feasibility using several approaches (eg, proportion of recruited participants eligible to participate in the study and recruitment method yields), we defined the primary measure as participant retention of ≥80% over the course of the intervention. At the end of the intervention, participants completed follow-up surveys that included questions about acceptability. Specifically, participants reported their level of satisfaction with each intervention component; frequency that each intervention component was read, used, or accessed; helpfulness of each intervention component; and satisfaction with the intervention overall. We also conducted poststudy interviews with a subset of participants.Secondary outcomes of objective and subjective MVPA were assessed at study enrollment and 6-month follow-up. To objectively measure PA, participants wore an accelerometer (ActiGraph wGT3X-BT). Although the staff instructed participants to wear the accelerometer for 7 days, minimum acceptable wear time was either 5 days with ≥600 minutes per day or 4 days with ≥3000 total minutes. To determine MVPA, we used an established minimum cutoff of 1952 counts per minute and a minimum bout of 10 minutes of PA [Characteristics of the neighborhood social and built environment were explored as potential moderators of intervention efficacy. Participants self-reported their perceptions about neighborhood safety and neighborhood social cohesion [We explored psychosocial variables as potential mediators of intervention efficacy. At study enrollment and 6-month follow-up, participants completed questionnaires about readiness to change PA (eg, precontemplation and contemplation) [
