Background: Children with intellectual disabilities can display behaviours that challenge, often associated with poor outcomes. Despite national policy commitment to co-production, little evidence is available on how such services deliver co-produced activity. Methods: Qualitative data were collected from three services that reported co-producing Positive Behaviour Support introductory workshops. Participants' experiences and perceptions of these workshops were described through individual semi-structured interviews conducted with staff and family carers (n = 24) and analysed using a Framework approach. Results: Two main themes were represented in the initial framework. Positives of Co-production included the advantages of obtaining and combining theoretical and practical knowledge, including personal and professional development for those delivering the intervention. Challenges to Implementation included the time and effort required to build a collaborative way of working, barriers to organisational support and family carers' history with services. Conclusions: Support, funding and resources need to be made available and protected to make co-production activities meaningful.
