We tested the hypothesis that lifetime physical and sexual abuse would have direct effects on self-harm (i.e., thoughts of self-harm, self-harming behaviors, and suicide attempts) and indirect effects on self-harm via negative appraisals of trauma and psychiatric symptoms in a sample of 242 clients with severe mental illness (SMI). Structural equation modeling partly confirmed our expectations. Although there was no direct effect between abuse and self-harm, abuse and self-harm appear to be fully mediated by negative appraisal and psychiatric symptoms. Limitations to this study include the cross-sectional nature of the research, which precludes firm causal inferences regarding the relationships among these factors. Longitudinal designs are needed to understand better the direct and indirect effects of abuse on people with SMI.
我们检验了这样一个假设，即终生的身体和性虐待会对自我伤害（即自我伤害的想法、行为和自杀企图）产生直接影响，并通过对创伤和精神症状的负面评价对自我伤害产生间接影响。在一个有严重精神疾病（SMI）的 242 名患者样本中，结构方程模型部分证实了我们的预期。尽管虐待与自我伤害之间没有直接影响，但虐待与自我伤害似乎完全被负面评价和精神症状所中介。本研究的局限性包括研究的横断面性质，这使得这些因素之间的关系无法做出坚定的因果推断。需要进行纵向设计，以更好地理解虐待对 SMI 患者的直接和间接影响。
