Short-video addiction (SVA) has become a growing concern among adolescents. Bullying victimization (BV) is considered a significant factor contributing to it, yet its relationship with SVA remains underexplored. This study investigated the role of BV in SVA, examining developmental and psychological pathways across middle school students (MSS; n = 1269), college students (CS; n = 1615) and a replicated college sample (RCS; n = 112). Descriptive statistics revealed significant correlations between SVA and BV, including subdimensions such as verbal, physical and relational bullying, as well as negative affect (NA). Mediation analyses showed that NA partially mediated the relationship between BV and SVA across both MSS and CS groups, although mediation effects were absent in addicted subgroups, highlighting differing psychological pathways between addicted and nonaddicted populations. Neuroimaging analyses in the RCS sample identified spontaneous functional brain activity linked to SVA in the inferior temporal gyrus (ITG) and parahippocampal gyrus (PHG), with intersubject representational similarity analyses (IS-RSA) further associating PHG and dorsomedial prefrontal cortex (DMPFC) activity patterns with intersubject variations in SVA. These findings underscore bullying victimization as a critical predictor of short video addiction, mediated by NA in nonaddicted groups, and illuminate spontaneous brain activity patterns associated with addiction.
短视频成瘾（SVA）已成为青少年中日益受到关注的问题。受欺凌（BV）被认为是导致这一问题的一个重要因素，但其与SVA的关系仍未得到充分探索。本研究调查了BV在SVA中的作用，考察了中学生（MSS；n = 1269）、大学生（CS；n = 1615）和一个重复的大学生样本（RCS；n = 112）中的发展和心理途径。描述性统计显示SVA与BV之间存在显著相关性，包括言语、身体和关系欺凌等子维度，以及消极情绪（NA）。中介分析表明，NA在MSS和CS组中部分介导了BV与SVA之间的关系，尽管在成瘾亚组中不存在中介效应，这突出了成瘾人群和非成瘾人群之间不同的心理途径。RCS样本中的神经影像学分析确定了颞下回（ITG）和海马旁回（PHG）中与SVA相关的自发功能性脑活动，主体间表征相似性分析（IS-RSA）进一步将PHG和背内侧前额叶皮质（DMPFC）的活动模式与SVA中的主体间差异联系起来。这些发现强调了受欺凌是短视频成瘾的一个关键预测因素，在非成瘾组中由NA介导，并揭示了与成瘾相关的自发脑活动模式。
