Non-suicidal self-injury (NSSI) is a significant public health concern, not only because of the personal and social cost of the behavior itself, but also because it increases risk for future self-injurious behaviors, including suicide attempts. NSSI is increasingly prevalent during adolescence, which highlights the need for research aimed at identifying modifiable risk factors that can be targeted to reduce future risk. Building from theoretical models that highlight interpersonal processes, this study examined whether adolescents with an NSSI history exhibit greater difficulty inhibiting attention to emotionally salient interpersonal stimuli (face), indexed via steady state visual evoked potentials (SSVEPs), which provide a direct neural index of the ability to inhibit attention to task-irrelevant stimuli.
Adolescent girls aged 13-17 with (n = 26) and without (n = 28) an NSSI history completed a change-detection computer task during which frequency-tagged SSVEPs were used to assess adolescents' ability to inhibit attention to affectively salient stimuli from spatially superimposed targets.
Compared with adolescents with no NSSI history, adolescents with NSSI demonstrated difficulty inhibiting attention to angry adult faces.
These findings underscore specific deficits in attentional filtering among girls with an NSSI history, which, if replicated and extended, could be a promising intervention target for reducing risk for future NSSI.
非自杀性自伤（NSSI）是一个严重的公共卫生问题，不仅因为这种行为本身给个人和社会带来了代价，还因为它增加了未来自伤行为（包括自杀企图）的风险。NSSI 在青少年中越来越普遍，这凸显了需要研究旨在确定可改变的风险因素，以便降低未来风险。本研究基于强调人际过程的理论模型，探讨了是否有 NSSI 病史的青少年在抑制对情绪相关的人际刺激（面孔）的注意力方面表现出更大的困难，这通过稳态视觉诱发电位（SSVEP）来衡量，SSVEP 提供了直接的神经指标来衡量抑制对任务无关刺激的注意力的能力。
年龄在 13 至 17 岁之间的有（n=26）和没有（n=28）NSSI 病史的青少年完成了一项变化检测计算机任务，在此期间，使用频率标记的 SSVEP 来评估青少年抑制对来自空间叠加目标的情绪相关刺激的注意力的能力。
与没有 NSSI 病史的青少年相比，有 NSSI 病史的青少年在抑制对愤怒成年面孔的注意力方面表现出困难。
这些发现强调了有 NSSI 病史的女孩在注意力过滤方面存在特定缺陷，如果得到复制和扩展，这可能成为减少未来 NSSI 风险的有希望的干预目标。
