It seems that different violent events work interactively, possibly creating a chronic state of stress. In accordance with this, prior studies have found that individuals who developed PTSD in response to a trauma are at increased risk of also suffering from PTSD after a subsequent trauma Though quantitative aspects of victimisation are important, so are qualitative aspects. The form of violence matters, as does the victim-perpetrator relationship. In this study, emotional violence was generally more strongly associated with symptoms of psychological ill health than other forms of violence (Tables 3 and 4). Also, violence from an intimate partner generally had the strongest association with self-reported symptoms of psychological ill health (Tables 5 and 6), a finding supported by some previous research [17]. However, though violence from an acquaintance/stranger showed the weakest association with symptoms of psychological ill health, it consistently contributed to higher OR when reported in addition to violence from other kinds of perpetrators. This is supported by previous findings that female victims of both community and partner violence reported more trauma symptoms than those reporting either community or partner violence alone [47]. When violence is part of both intimate relationships and more distant ones, victims might be deprived of all sanctuaries, which may impede the recovery process. For poly-victims compared to other victims, it has been hypothesized that when more environments as well as more people are associated with traumatic experiences, this may lead to more difficulties in resisting negative self-attribution [7].
