Objective: Substance use among incarcerated people is prevalent in prisons worldwide. Little is known, however, about the factors associated with substance use during incarceration. Of special interest is the role of childhood abuse and social support on prison-based substance use, as these variables have been found to influence the use of alcohol and drugs in the community. Method: We used a random sample of 943 male inmates in southeast Spain to estimate the prevalence and pattern of substance use during the past 3 months of incarceration. Using logit modeling techniques, we assessed the relationship between substance use in prison and measures of childhood abuse, social support, and resiliency. Results: Childhood trauma experiences were most prevalent among mono- and poly-substance-use groups and were strongly associated with prison-based substance use. Social support and resiliency were highest among substance nonusers and served a protective role: Higher levels of external or internal support reduced the likelihood of prison-based substance use. Conclusions: Findings point to the need for additional training for social workers and correctional personnel in understanding patterns of prison-based substance use.

西班牙男性囚犯中物质使用的预测指标：虐待儿童和社会支持的作用

目的：被监禁人员中的毒品使用在世界各地的监狱中普遍存在。然而，关于在监禁期间使用毒品的相关因素知之甚少。特别令人关注的是，儿童期虐待和社会支持对基于监狱的毒品使用的作用，因为已经发现这些变量会影响社区的酒精和毒品使用。方法：我们在西班牙东南部使用943名男性囚犯的随机样本来估计过去3个月监禁期间毒品使用的流行程度和模式。使用logit建模技术，我们评估了监狱中的毒品使用与儿童虐待，社会支持和复原力的度量之间的关系。结果：童年创伤经历在单物质和多物质使用人群中最为普遍，并且与基于监狱的物质使用密切相关。在非毒品使用者中，社会支持和抵御能力最高，并且起到了保护作用：较高水平的外部或内部支持减少了监狱使用毒品的可能性。结论：研究结果表明，有必要对社会工作者和教养人员进行额外的培训，以了解基于监狱的毒品使用方式。
