Aside from depression and anxiety, less is known about the relationship of problematic smartphone use (PSU) to other psychopathology-related variables. The authors' aim was to test previously neglected variables in relation to PSU: rumination and excessive reassurance seeking behavior (ERSB). The authors recruited 295 college students for a web-based survey of smartphone use frequency, PSU, depression and anxiety, ruminative thinking, and ERSB. The authors tested linear regression and mediation models, assessing rumination and ERSB as mediating associations between depression/anxiety severity with PSU, adjusting for age, sex, and smartphone use frequency. Results demonstrate that ERSB was significantly related to PSU severity, and ERSB mediated the association between rumination and PSU. Furthermore, the combination of rumination and ERSB mediated relations between both depression and anxiety severity with PSU. Results provide evidence for ERSB as an important variable in understanding relationships between psychopathology symptoms and PSU severity among college students.

寻求过多的保证会调解反省和有问题的智能手机使用之间的关系。

除了抑郁和焦虑外，关于智能手机使用问题（PSU）与其他与心理病理学相关的变量之间的关系所知甚少。作者的目的是测试与PSU相关的先前被忽略的变量：反省和过度保证寻求行为（ERSB）。作者招募了295名大学生，进行基于网络的智能手机使用频率，PSU，抑郁和焦虑，反刍思维和ERSB调查。作者测试了线性回归和中介模型，评估了反刍和ERSB作为PSU与抑郁/焦虑严重程度之间的中介关系，并针对年龄，性别和智能手机使用频率进行了调整。结果表明，ERSB与PSU严重程度显着相关，并且ERSB介导了反刍与PSU之间的关联。此外，反刍和ERSB介导的PSU抑郁与焦虑严重程度之间的关系。结果为ERSB作为了解大学生心理病理症状与PSU严重性之间关系的重要变量提供了证据。
