Bringing a mentalizing framework to understanding mothers with addiction: The groundbreaking work of Nancy E. Suchman.

Nancy Suchman is remembered as a pioneer whose mentalization-based intervention-Mothering from the Inside Out (MIO)-transformed the treatment of parents struggling with substance use disorders. Specifically, Suchman's work highlighted the neural mechanisms underlying substance use disorders and identified the promotion of parental mentalizing as a key therapeutic focus in enhancing early parent-child relationships. Her work transformed parenting support models for this population of parents. Several randomized controlled trials (RCT) show the effectiveness of MIO in promoting parental reflective functioning (PRF) and positive relational outcomes in parents with substance use disorders and their children. Suchman's MIO model has since been extended to parenting in many contexts. She is also remembered as a generous colleague, a gifted researcher and clinician, and an inspiration to generations of researchers and practitioners working with parents who aspire to raise healthy, secure children despite multiple challenges and adversities. This special issue compiles the work of researchers inspired by Suchman as they carry on her legacy in examining aspects of parental mentalization. Collectively, the research presented yields confirmation of MIO core assumptions, offers new insights into roles of positive sentiment and savoring in mentalization processes, and presents evaluations of MIO in multiple contexts and with new adaptations.
