The Parents under Pressure program was developed for families with parental substance misuse, mental health, intergenerational trauma, and significant financial and social disadvantage. In this article, we provide an overview of the program, and a description of the training and implementation support process we adopted for the field. Drawing from implementation science, we describe the implementation strategies and outcomes that inform this work. We conclude with a description of training events for practitioners in (i) Central Australia working with Aboriginal families and (ii) with mothers in residential mother and child facility in the Republic of Ireland.
