The investigators longitudinal mixed-methods study will use a one-group repeated measures intervention design coupled with qualitative methods to provide a comprehensive view of the feasibility, acceptability, and preliminary effects of the MOMS intervention. Semi-structured interviews, recruitment and retention numbers, and participant logs will be used to evaluate feasibility and acceptability of the intervention (Specific Aim 1). Recently collected archival comparison group data from an existing study will be used to contribute to explorations of preliminary effects of the intervention by comparing longitudinal psychobehavioral data, birth weight data, and genome-wide and gene-specific DNAm data (Specific Aims 2 and 3).
