Outcome results
Primary
Feasibility of the Intervention (Completion)
% of participants who remain connected to intervention account at 8 weeks (end of intervention) There are no statistical analyses because pre-registered primary outcomes are descriptive in nature.
Time frame: 8 weeks
Population: This measure is only reported among the intervention group arm because intervention acceptability can only be measured among those assigned to the intervention group. This measure would be irrelevant for the control group.
