Frontiers | How do core personality traits influence short video dependence among Chinese college students? Evidence from a serial mediation analysis under the I-PACE model

New research provides crucial insights into how core personality traits drive problematic short video use among Chinese college students. The study, applying the I-PACE theoretical model, identifies a clear pathway where specific personality characteristics lead to increased dependence on platforms like Douyin and Kuaishou.

The investigation found that neuroticism—a tendency toward anxiety and emotional instability—is a significant predictor of dependence. This trait often leads students to use short videos as a maladaptive coping mechanism for stress. Conversely, conscientiousness, associated with self-discipline and organization, acts as a protective factor, reducing the risk of developing compulsive usage habits.

Crucially, the analysis reveals a serial mediation process. Certain personality types first increase an individual's susceptibility to specific cognitive biases and emotional responses to online content. This, in turn, leads to the formation of habitual, cue-driven cravings to use short video apps. The cycle reinforces itself, making it difficult for students to regulate their viewing time, often at the expense of academic responsibilities, sleep, and real-world social interaction.

Experts suggest these findings underscore the need for tailored interventions on university campuses. Rather than a one-size-fits-all approach, support mechanisms could address the underlying psychological needs driving the behavior. Promoting digital literacy and healthy coping strategies for stress management is seen as essential to mitigating the negative impacts of this pervasive digital trend.
