摘要
Suicide among prisoners has long been a concern. Childhood trauma has been considered as a distal risk factor for suicide risk among prisoners, but the underlying influencing mechanism has been less studied. There is evidence that alexithymia and depressive symptoms may play important roles in the relationship between childhood trauma and suicide risk. The present study aims to confirm alexithymia and depressive symptoms as risk factors of suicide risk, and to clarify the interactions among childhood trauma, alexithymia, depressive symptoms, and suicide risk in Chinese male prisoners. Data were collected from 430 male prisoners in China. Childhood trauma, alexithymia, depressive symptoms, and suicide risk are measured. The current study has found that childhood trauma, alexithymia, depressive symptoms, and suicide risk were common in China's prison population, with a prevalence of 87.9%, 29.1%, 80.7%, and 13.0%, respectively. Childhood trauma, alexithymia, and depressive symptoms were positively associated with suicide risk in these prisoners. Alexithymia and depressive symptoms showed significant mediating effects on the association of childhood trauma and suicide risk. The further analyses showed that a significant direct effect on suicide risk was found for childhood abuse but not for childhood neglect. Abuse influenced suicide risk both directly and indirectly, whereas neglect influenced suicide risk through mediating paths only. Prisoners with childhood trauma are at higher risk of suicide, and alexithymia and depressive symptoms mediated the relationship between childhood trauma and suicide risk. Attention should be paid to the alexithymia and depressive symptoms of prisoners who have traumatic experience, and the subtypes of childhood trauma should be considered when it needs to establish and conduct precise intervention.
