The Moving Parents and Children Together (M‐PACT) programme is one of the growing number of interventions tailored to meet the multiple and complex needs of children and families affected by parental substance misuse. This paper pulls together the qualitative findings from 13 evaluated M‐PACT programmes in England. Sixty‐four families attended an M‐PACT programme, including 82 children and 75 adults. Qualitative data were collected from 37 children, 36 adults and over 30 group facilitators. Six themes are discussed: engaging with M‐PACT, shared experiences, understanding addiction, changes in communication, healthier and united families, and ending M‐PACT. The majority of families benefitted in a range of ways from the programme: meeting others who were experiencing similar problems, greater understanding about addiction and its impact on children and families improving communication within the family. In many families there was more openness and honesty, stronger relationships and more time as families, and a reduction in arguments and conflict. The key findings are discussed in terms of the potential for interventions of this kind to reduce family‐related harm from parental substance misuse.
