Gory social media videos can cause trauma

London: Unedited violent news stories in social media can cause viewers to experience symptoms similar to post-traumatic stress disorder (PTSD), says a study.

"Social media has enabled violent stories and graphic images to be watched by the public in unedited horrific detail. Watching these events and feeling the anguish of those directly experiencing them may impact on our daily lives," said researcher Pam Ramsden from the University of Bradford in Britain.

In this study, the researchers wanted to see if people would experience longer lasting effects such as stress and anxiety, and in some cases post-traumatic stress disorders from viewing these images.

Some 189 participants (participant's mean age was 37 years old with an almost even gender split) completed clinical assessments for PTSD, a personality questionnaire, a vicarious trauma assessment and a questionnaire concerning different violent news events on social media or the internet.

These included the 9/11 Twin Tower attacks in the US, school shootings and suicide bombings.

Analysis indicated that 22 percent of participants were significantly affected by the media events.

These individuals scored high on clinical measures of PTSD even though none had previous trauma, were not present at the traumatic events and had only watched them via social media.

Those who reported viewing the events more often were most affected.

"With increased access to social media and the internet via tablets and smartphones, we need to ensure that people are aware of the risks of viewing these images and that appropriate support is available for those who need it," Ramsden pointed out.

The findings are scheduled to be presented today, at the Annual Conference of the British Psychology Society in Liverpool.
