摘要

短视频成瘾(SVA)已成为青少年中日益严重的问题。欺凌受害(BV)被认为是导致这一现象的重要因素,但其与 SVA 的关系仍未得到充分探讨。本研究调查了 BV 在 SVA 中的作用,研究了中学生(MSS; n = 1269)、大学生(CS; n = 1615)和重复的大学样本(RCS; n = 112)的发展和心理路径。描述性统计显示,SVA 与 BV(包括语言欺凌、身体欺凌和关系欺凌等子维度)以及消极情绪(NA)之间存在明显的相关性。中介分析表明,在MSS和CS组中,NA对BV和SVA之间的关系起到了部分中介作用,但在成瘾亚组中却没有中介效应,这凸显了成瘾人群和非成瘾人群之间不同的心理路径。在RCS样本中进行的神经影像分析确定了颞下回(ITG)和海马旁回(PHG)中与SVA相关的自发脑功能活动,而受试者间表征相似性分析(IS-RSA)进一步将PHG和背内侧前额叶皮层(DMPFC)的活动模式与SVA的受试者间差异联系起来。这些发现强调了欺凌受害是短视频成瘾的一个关键预测因素,在非成瘾群体中由NA介导,并阐明了与成瘾相关的自发大脑活动模式。

The Impact of Bullying Victimization on Short Video Addiction in Adolescents: The Role of Emotional Distress and Neural Mechanisms

The Impact of Bullying Victimization on Short Video Addiction in Adolescents: The Role of Emotional Distress and Neural Mechanisms

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.

期刊介绍: Addiction Biology is focused on neuroscience contributions and it aims to advance our understanding of the action of drugs of abuse and addictive processes. Papers are accepted in both animal experimentation or clinical research. The content is geared towards behavioral, molecular, genetic, biochemical, neuro-biological and pharmacology aspects of these fields. Addiction Biology includes peer-reviewed original research reports and reviews. Addiction Biology is published on behalf of the Society for the Study of Addiction to Alcohol and other Drugs (SSA). Members of the Society for the Study of Addiction receive the Journal as part of their annual membership subscription.
