Several studies suggest parental substance use, while not always the case, exposes children to a higher risk of physical, psychological, behavioral and emotional problems. Identifying interventions that best support the parent and child needs is imperative. The PuP programme aims to improve family functioning and child outcomes by supporting parents who are or have been drug or alcohol dependent. PuP combines psychological principles relating to parenting, child behavior and parental emotion regulation within a case-management model. The current study was the first evaluation of the PuP program in a residential setting globally. Twenty-three women took part in pre and post-program qualitative interviews. Guilt was a dominant theme across interviews. The principal expectation of participants was to improve their relationships and access to their children. The benefits of the PuP program to the women and their children, as reported by participants, were immediate and direct. As the women progressed through the program, they were visibly building belief in their abilities to parent.
