Cross-sectional studies have shown that both stressors and personality vulnerability are risk factors for adolescent problematic Internet use (PIU). However, little is known about how both categories of factors in combination may contribute to the longitudinal development of PIU among adolescents. The aims of this study were to document the developmental pattern of PIU among adolescents and to examine how stressful life events and the Big Five personality traits jointly affect the development of PIU. We tested three competing models: the additive, diathesis-stress, and social push models. A total of 1,365 adolescents participated in a 3-year longitudinal study. Hierarchical linear modeling indicated that PIU among adolescents increased over the 3-year period. After controlling for demographics and the Big Five personality traits, stressful life events (a time-varying predictor) were positively correlated with the initial level of, and the rate of change in, PIU. After controlling for demographics and stressful life events, four of the time-invariant Big Five personality dimensions had a significant effect on the initial level of PIU. Low Agreeableness, low Conscientiousness, high Openness, and high Neuroticism were positively associated with high initial PIU. In addition, Extraversion was negatively associated with and Conscientiousness was positively associated with the rate of change in PIU. The interaction effect between the personality and stressors was not significant. Therefore, the data provided support for the additive model, indicating that stressful life events and personality dimensions each make a unique contribution to PIU and that both should be considered in the prevention of adolescent PIU.

横断面研究表明，应激源和人格脆弱性都是青少年问题性互联网使用（PIU）的风险因素。然而，人们对这两类因素如何共同作用，从而导致青少年 PIU 的纵向发展知之甚少。本研究的目的是记录青少年 PIU 的发展模式，并研究应激性生活事件和大五人格特质如何共同影响 PIU 的发展。我们检验了三个竞争模型：累加模型、素质-应激模型和社会推动模型。共有 1365 名青少年参加了一项为期 3 年的纵向研究。分层线性模型表明，青少年的 PIU 在 3 年内呈上升趋势。在控制了人口统计学和大五人格特质后，应激性生活事件（时变预测因子）与 PIU 的初始水平和变化率呈正相关。在控制了人口统计学和应激性生活事件后，大五人格特质的四个时间不变维度对 PIU 的初始水平有显著影响。低宜人性、低尽责性、高开放性和高神经质与高初始 PIU 呈正相关。此外，外向性与 PIU 的变化率呈负相关，尽责性与 PIU 的变化率呈正相关。人格与应激源的交互作用不显著。因此，数据支持累加模型，表明应激性生活事件和人格维度各自对 PIU 有独特的贡献，在预防青少年 PIU 时应同时考虑这两个因素。（PsycINFO 数据库记录（c）2019 APA，保留所有权利）。
