This paper presents a systematic review of the evidence on the use of social media by people with intellectual disability. Method: Ten primary studies published in the English language between January 2000 and June 2014 were identified from electronic database searches, correspondence with experts and citation tracking. Examination of these themes revealed that some people with intellectual disability are having positive experiences using social media in terms of friendships, development of social identity and self-esteem and for enjoyment. However barriers that stop people with intellectual disabilities from successfully accessing social media were identified.
