Positive behaviour support (PBS) is often used with people with learning disabilities to improve their quality of life and support a reduction in behaviour that challenges. To increase the effectiveness of a PBS intervention, it is important that the person concerned is involved in its development, which may require creativity on the part of professionals. This article presents the story of Jack (a pseudonym), an autistic young person with a mild learning disability whose behaviour that challenges had increased in frequency and severity. The author describes how he supported Jack to contribute to the development of his PBS intervention by using an accessible communication method, Talking Mats, and to engage in the PBS intervention through co-production of a video.
