IntroductionOccupational therapists routinely report low levels of confidence in addressing needs related to sexuality and intimacy. These issues are compounded when supporting clients with intellectual disability, due to prevailing assumptions about capacity and few practical support resources. At a disciplinary level, there is ongoing discourse around how to best conceptualise and support sexual and gender identities generally, within models of human occupation. Leveraging interdisciplinarity, where sexuality overlaps as a sphere of interest, can aid the development of practical support resources. Engagement with sociology (focussed on relationality) and disability studies (focussed on embodiment) offers a generative path forward.MethodsThe deliberative dialogues framework was used to develop a co‐designed resource by occupational therapists for occupational therapists. Six Australian occupational therapists with experience working with clients with intellectual disability and/or sexuality were purposively recruited to participate in co‐design groups. Using the eight features of deliberative dialogue, data was collected and analysed by an interdisciplinary research team to collaboratively produce a practical support resource.ResultsParticipants agreed the greatest need was to develop a resource for clinicians, to support conversations with clients about sexuality. Five key themes emerged: (1) Theoretical explanations addressing why sexuality is important must be paired with practical advice; (2) make a conversational call to action from ‘OTs’ for ‘OTs’ by locating sexuality within the domain of occupational therapy; (3) make explicit that people with intellectual disability are sexual beings; (4) need for self‐reflection; and (5) demonstrate how existing understandings of occupation apply to sexuality.ConclusionA resource in the form of a brochure was developed, intended to be used as a conversation primer. The process used to develop the resource demonstrated the value of interdisciplinary collaboration and the utility of deliberative dialogue as a co‐design method.
