To determine the prevalence and correlates of violent victimisation among homeless people in inner-Sydney.
Cross-sectional design. Clients of a shelter for homeless, substance-using adults were interviewed about their drug use, mental health and violent victimisation in the previous 12 months. Logistic regression was used to identify factors associated with victimisation.
Participants reported complex drug use histories and high levels of depression, post-traumatic stress disorder (PTSD) and schizophrenia or other psychotic disorders. Forty-eight per cent of participants reported past year victimisation. In univariate analyses, being female, schizophrenia/psychotic disorder, PTSD, depression and regular use of psychostimulants were associated with increased risk of victimisation. In multivariate analyses, regular use of psychostimulants (odds ratio [95% CI] 5.07 [1.53-16.84]), schizophrenia or other psychotic disorder (3.13 [1.24-7.9], and depression (2.65 [1.07-6.59]) were associated with increased risk of victimisation.
This sample of homeless, substance-using adults experienced high levels of violence. People with poor mental health and regular psychostimulant users were at greater risk of victimisation. A longitudinal study to determine whether victimisation prolongs homelessness is warranted. Clinical staff working with homeless populations need to be aware of the likelihood of past and future victimisation and its effects on mental health. Homeless persons may benefit from learning to identify risk situations for victimisation and how to de-escalate potentially violent situations.
确定悉尼市中心无家可归者中暴力受害情况的患病率及其相关因素。
采用横断面设计。对一家收容无家可归、使用毒品的成年人的庇护所的服务对象进行访谈，了解他们在过去12个月中的吸毒情况、心理健康状况和暴力受害情况。采用逻辑回归分析来确定与受害相关的因素。
参与者报告了复杂的吸毒史以及高水平的抑郁、创伤后应激障碍（PTSD）和精神分裂症或其他精神障碍。48%的参与者报告在过去一年中遭受过伤害。在单因素分析中，女性、精神分裂症/精神障碍、PTSD、抑郁以及经常使用精神兴奋剂与受害风险增加有关。在多因素分析中，经常使用精神兴奋剂（优势比[95%置信区间]5.07[1.53 - 16.84]）、精神分裂症或其他精神障碍（3.13[1.24 - 7.9]）以及抑郁（2.65[1.07 - 6.59]）与受害风险增加有关。
这个无家可归、使用毒品的成年人群体经历了高水平的暴力。心理健康状况不佳的人和经常使用精神兴奋剂的人受害风险更大。有必要进行一项纵向研究，以确定受害是否会延长无家可归的时间。与无家可归人群打交道的临床工作人员需要意识到过去和未来受害的可能性及其对心理健康的影响。无家可归者可能会从学习识别受害的风险情况以及如何缓和潜在的暴力情况中受益。
