Relationships between bullying features & suicidal behaviour of inmates were examined. The files of 95 suicide victims in jails & prisons in The Netherlands were examined for reports of bullying. In addition, 221 nonsuicidal inmates & 53 suicidal jail inmates were interviewed. The files of 34% of the suicide victims noted the victim had felt bullied. Bullying, especially serious bullying, was relatively often reported by suicidal inmates & by vulnerable inmates. Different types of bullies were associated with different forms of bullying & different degrees of suicide risk. Results suggest that bullying & suicide risk are related & that a distinction should be made between mild & serious features of bullying. (48 refs.)
