Childhood trauma AND Nonsuicidal self-injury

Childhood trauma increases NSSI risk through impaired mentalization (both hypo- and hypermentalization), as shown in a large adolescent sample. However, salivary oxytocin levels were not associated with NSSI, mentalization, or trauma, indicating it is not a reliable biomarker for this behavior in community populations.

一项针对大型青少年样本的研究显示，儿童期创伤可通过受损的心理化（mentalization）能力（包括低心理化与高心理化两种情况）提升非自杀性自伤（Non-Suicidal Self-Injury, NSSI）的风险。然而，唾液催产素水平与非自杀性自伤、心理化能力及儿童期创伤均无关联，这表明催产素并非社区人群中该类行为的可靠生物标志物。
