Dr Caroline Richards’ PhD research investigating the risk markers and causes of self-injurious behaviour in autism spectrum disorder was highlighted in a recent Channel 4 News article. The research demonstrated that environmental triggers, behavioural characteristics and the presence of health problems more than double the risk of children with autism engaging in self-injury. These data contribute to the ongoing debate about the causes and treatment of self-injury in children and adults with autism spectrum disorder. Children who display self-injury rarely receive appropriate psychological and medical assessment and intervention, and atypical antipsychotics are frequently prescribed, despite the strong evidence base for psychological interventions.
