As Nye states in Huffpost-Lifestyle UK
"If it looks like a dog, if it barks like a dog, and if overall it behaves like a dog, then it is most likely to be a dog. In the case of PTSD caused by bullying and abuse at work, this is a particularly black dog."
In recent research, people who had been bullied have been found to suffer from post-traumatic stress disorder. The researcher went further, stating that
'Traumatic experiences or strains imposed on us by others can often hurt more than accidents.' (emphasis added).
This relates to the finding that bullying has a more significant effect on victims than sexual abuse.
Furthermore, the American Academy of Child and Adolescent Psychiatry have issued a policy statement recognising bullying as a serious medical and public health issue.
The results of our survey indicate that a considerably number of staff/students currently or previously at the University of Newcastle are suffering from symptoms of post-traumatic stress disorder.
