This study explored the relationship between childhood trauma and short-video addiction (SVA) symptoms, alongside exploring the potential morphological substrate underlying this association. Among three independent datasets (Dataset 1: n = 980; Dataset 2: n = 1260; Dataset 3: n = 190), we found consistent positive correlations between childhood trauma and SVA symptoms, particularly in emotion abuse and physical neglect sub-dimensions. Additionally, we identified differential patterns in high- and low-risk addiction groups, with emotional neglect playing a critical role in the development of addiction, especially among low-risk individuals. Structural MRI data were collected in dataset 3, univariate analysis revealed that gray matter volumes (GMV) in the dorsolateral prefrontal cortex (dlPFC), orbitofrontal cortex, dorsomedial prefrontal cortex, frontal pole, and superior temporal gyrus were positively correlated with SVA symptoms. Within this dataset, mediation analysis showed that GMV in the dlPFC mediated the effect of physical neglect on SVA symptoms, suggesting that childhood trauma, particularly physical neglect, influences SVA symptoms through GMV strength in prefrontal cortex. These findings emphasize the critical role of childhood trauma in the development of short video addiction and underscore the need for targeted interventions addressing both psychological and neural aspects of addiction.
本研究探讨了童年创伤与短视频成瘾（SVA）症状之间的关系，并探究了这种关联背后潜在的形态学基础。在三个独立数据集（数据集1：n = 980；数据集2：n = 1260；数据集3：n = 190）中，我们发现童年创伤与SVA症状之间存在一致的正相关，尤其是在情感虐待和身体忽视子维度中。此外，我们在高风险和低风险成瘾组中发现了不同的模式，情感忽视在成瘾发展中起着关键作用，特别是在低风险个体中。在数据集3中收集了结构MRI数据，单变量分析显示，背外侧前额叶皮质（dlPFC）、眶额皮质、背内侧前额叶皮质、额极和颞上回的灰质体积（GMV）与SVA症状呈正相关。在该数据集中，中介分析表明，dlPFC中的GMV介导了身体忽视对SVA症状的影响，这表明童年创伤，尤其是身体忽视，通过前额叶皮质的GMV强度影响SVA症状。这些发现强调了童年创伤在短视频成瘾发展中的关键作用，并强调了针对成瘾的心理和神经方面进行有针对性干预的必要性。
