This paper describes a piece of research undertaken with a sample of male clients in a secure hospital setting for adults with a diagnosis of mental illness and/or personality disorder and deafness. A comparative analysis was undertaken to explore the functions for harmful sexual behaviour (HSB) in this client group comparative to functions of HSB in hearing clients. The findings of the research are discussed in relation to theories of harmful sexual behaviour. Recommendations for how the findings may inform treatments for HSB in this client group are also discussed, with implications for practice noted.
Key words: Deaf, Harmful sexual behaviour, Positive Behavioural Support (PBS), Therapy, Risk, Offending.
