Helpline Pilot Factorial Trial

The pilot factorial trial will (1) evaluate feasibility, acceptability, and fidelity of the intervention components (Aim 2.1), and (2) collect proof-of-concept data on the impact of the components on the proximal (motivation, self-efficacy, and self-regulation) and distal (quantity and frequency of HED) outcomes (Aim 2.2). Participants will include 120 postpartum mothers recruited from social media. The investigators will conduct a pilot 2X2X2 balanced full factorial trial, with 4 factors (1 constant, 3 randomized to 2 levels each) and 8 study conditions. The 4 factors will include: (1) Standard Helpline (constant); (2) Motivational Interviewing (yes vs. no); (3) Coping skills training (yes vs. no); (4) Automated messaging (yes vs. no). Participants will be randomly assigned to one of 8 study conditions, which will determine which combination of intervention components participants receive.

In keeping with the goals of the R34 mechanism, the emphasis will be on feasibility evaluation and not on hypothesis testing, with a goal of obtaining preliminary information about implementation feasibility and effect sizes of the intervention components to inform a fully-powered optimization trial in a future R01. Thus, investigators will examine main and interactive effects of the intervention components in an exploratory manner to inform refining the components for further testing in a future study. Participants will include 120 postpartum mothers recruited from social media.

Participants will be randomly assigned to one of 8 study conditions, which will determine which combination of intervention components participants receive. The study will last for 24 weeks. Following informed consent, participants will complete a baseline assessment and randomization, at which point participants will be enrolled. The active intervention period will begin in Week 2, with the number of scheduled sessions varying by condition. Participants will complete a post-intervention assessment and qualitative interview after the final intervention contact (varying by condition), and follow-up assessments at 3- and 6-months post-baseline.
