Existing research has demonstrated that problematic smartphone use (PSU) may reflect a composition of heterogeneous symptoms, with individual PSU symptoms uniquely related to predisposing variables. The Big Five personality traits represent one of the most frequently examined predisposing variables in relation to PSU. However, no studies to date have examined the trait-to-symptom association between the Big Five personality traits and PSU. Using a network analysis approach, we aimed to understand: 1) specific pathways linking each of the Big Five personality traits to PSU symptoms and 2) the bridging effects of each Big Five personality trait on the PSU symptom cluster.
A regularised graphical Gaussian model was estimated among 1,849 Chinese university students. PSU symptoms were assessed with items from the Problematic Smartphone Use Scale. Facets of the Big Five personality traits were assessed with the subscales of the Chinese Big Five Personality Inventory-15. An empirical index (i.e., bridge expected influence) was used to quantify bridge nodes.
Results revealed specific and distinct pathways between the Big Five personality traits and PSU symptoms (e.g., Neuroticism-Escapism/Avoidance, Conscientiousness-Preoccupation and Extraversion-Escapism/Avoidance). Further, Neuroticism showed the highest positive bridge centrality among the Big Five personality traits, while Conscientiousness had the highest negative bridge centrality.
The current study provided direct empirical evidence concerning specific pathways between the Big Five personality traits and PSU symptoms and highlighted the influential role of Neuroticism and Conscientiousness as potential targets for early detection and treatment of PSU.
现有研究表明，智能手机使用问题（PSU）可能反映了一组异质症状，个体 PSU 症状与潜在变量有独特的关联。五大人格特质是与 PSU 相关的最常被研究的潜在变量之一。然而，迄今为止，还没有研究检验五大人格特质与 PSU 之间的特质-症状关联。本研究采用网络分析方法，旨在理解：1）五大人格特质与 PSU 症状之间的特定联系路径；2）每个五大人格特质在 PSU 症状群上的桥接作用。
在 1849 名中国大学生中，估计了正则化图形高斯模型。使用来自智能手机使用问题量表中的项目评估 PSU 症状。采用大五人格问卷-15 的子量表评估五大人格特质的各个方面。使用实证指标（即桥接预期影响）量化桥接节点。
结果揭示了五大人格特质与 PSU 症状之间的具体和独特的联系路径（例如，神经质-逃避/回避，尽责性-关注，外向性-逃避/回避）。进一步的，神经质在五大人格特质中表现出最高的正桥接中心度，而尽责性则表现出最高的负桥接中心度。
本研究提供了关于五大人格特质与 PSU 症状之间具体联系路径的直接实证证据，并强调了神经质和尽责性作为 PSU 早期检测和治疗的潜在目标的重要作用。
