People with autism are approximately twice as likely to die from drowning than members of the general population. Drowning can take place in quite small bodies of water. Therefore, acquiring good water safety skills is of the utmost importance. A systematic review of research into effective behavioural interventions for water safety and swim skills was conducted. In total, 11 studies were identified. Findings suggest that behaviourally based interventions can improve a range of water safety and swim skills in individuals with autism.
