Treating pregnant individuals with ADHD may improve parent and child wellbeing, parent-child interactions, and psychosocial familial factors to enhance family resilience and reduce prevalence/severity of child mental health disorders. Using the information provided from stakeholder interviews and adaptations of an existing CBT intervention for parents of children with ADHD, the current study will develop the MomMA (Moms Managing ADHD) intervention and implement it via an open clinical trial (n=10 pregnant individuals), delivered by masters-level women's health behavioral therapists. Investigators will examine treatment acceptability, feasibility, and appropriateness, as well as implementation factors (fidelity, adherence, facilitators/barriers) and qualitative data (e.g., feedback interviews). In addition, quantitative data (self-reported symptoms, parenting, and home environment measures; observed parent and child behavior; parent reported child temperament/behavior) will be used to assess parent and child outcomes following the intervention. This mixed-methods model will offer a comprehensive examination of the MomMA intervention and inform a refined intervention model.
