They have now confirmed the ‘selfitis’ does indeed exist and have even developed a ‘Selfitis Behaviour Scale’ which can be used to assess its severity.

Dr Mark Griffiths, Distinguished Professor of Behavioural Addiction in Nottingham Trent University’s Psychology Department, said: “A few years ago, stories appeared in the media claiming that the condition of selfitis was to be classed as a mental disorder by the American Psychiatric Association.

“Whilst the story was revealed to be a hoax, it didn’t mean that the condition of selfitis didn’t exist. We have now appeared to confirm its existence and developed the world’s first Selfitis Behaviour Scale to assess the condition.”
