Problematic use of the internet (PUI) and self-injurious behaviors (SIB) associate in adolescents and both relate to impulsivity. However, studies have not examined whether difficulties in impulse control are shared in adolescents with PUI and SIB, and how PUI relates to SIB frequency and impairment. Here, exploratory factor analysis was performed on a PUI questionnaire based on the Minnesota Impulse Disorder Interview, using survey data from 2,912 Connecticut high-school students. Regression analyses evaluated relationships between PUI factor scores and correlates of SIB. Moderation analyses examined impulsivity and sensation-seeking in relationship to PUI factors and SIB. Two PUI factors were extracted. The first PUI factor was associated with lifetime SIB, frequency, severity, urges, rising tension, and self-perceived problems with SIB. The second factor was associated with lifetime SIB and attempts to reduce SIB. Impulsivity and sensation-seeking associated with PUI factors and SIB, but did not moderate relationships between PUI and SIB. Findings suggest that PUI and SIB are related by difficulties in impulse control, and poor control over internet use is associated with more impairing SIB in adolescents who self-injure. Further research should investigate possible interventions targeting impulsivity and sensation-seeking to prevent PUI and SIB in youth.
网络使用问题（PUI）和自伤行为（SIB）在青少年中相关联，两者都与冲动有关。然而，目前的研究尚未检验在具有 PUI 和 SIB 的青少年中，冲动控制困难是否存在共病，以及 PUI 与 SIB 的频率和损害程度之间的关系。本研究采用康涅狄格州 2912 名高中生的调查数据，基于明尼苏达州冲动障碍访谈，对 PUI 问卷进行了探索性因子分析。回归分析评估了 PUI 因子得分与 SIB 相关因素之间的关系。调节分析检验了冲动性和寻求刺激与 PUI 因素和 SIB 的关系。提取了两个 PUI 因子。第一个 PUI 因子与 SIB 的终生发作、频率、严重程度、冲动、紧张加剧和对 SIB 问题的自我感知有关。第二个因子与 SIB 的终生发作和试图减少 SIB 有关。冲动性和寻求刺激与 PUI 因子和 SIB 有关，但不能调节 PUI 和 SIB 之间的关系。研究结果表明，PUI 和 SIB 是由冲动控制困难引起的，并且在自我伤害的青少年中，对互联网使用的控制不佳与更具损害性的 SIB 有关。进一步的研究应调查针对冲动性和寻求刺激的可能干预措施，以预防青少年的 PUI 和 SIB。
