Adolescence often is characterized by the onset of social anxiety and risk taking; yet, not all youth are anxious and/or risk takers. There are several factors that may help differentiate youth with anxiety (e.g., threat sensitivity and emotion dysregulation) and youth who take risks (e.g., impulsivity and emotion dysregulation). We conducted a latent class analysis to identify groups of youth who differ in these processes, and then investigated group differences on the error-related negativity, an ERP that has been differentially associated with threat sensitivity and impulsivity.
Youth (N = 1313, M = 11, range = 8-15 years) completed a survey assessing their emotion dysregulation, sensitivity to threat, and impulsivity. A subsample (N = 424) also completed a go/no-go task while EEG was recorded.
Four groups were identified with differential levels of emotion dysregulation, sensitivity to threat, and impulsivity. Adolescents had greater odds than children of being in the High_Dysregulation/ThreatSensitivity or ModerateDysregulation/HighImpulsivity Groups in comparison to two other groups with lower scores. The High_Dysregulation/ThreatSensitivity Group had the largest ERN, while the ModerateDysregulation/HighImpulsivity Group had the smallest ERN. The ERN may be a potential biomarker to help distinguish between different profiles of adolescents who may be at risk for either anxiety or risk taking.
青春期的特点通常是社交焦虑和冒险行为的开始；然而，并非所有的年轻人都是焦虑和/或冒险的。有几个因素可以帮助区分有焦虑的年轻人（例如，威胁敏感性和情绪调节障碍）和冒险的年轻人（例如，冲动和情绪调节障碍）。我们进行了潜在类别分析，以确定在这些过程中存在差异的青年群体，然后研究了与威胁敏感性和冲动性相关的错误相关负波（ERP）的群体差异。
青年（N=1313，M=11，范围为 8-15 岁）完成了一项调查，评估他们的情绪调节、对威胁的敏感性和冲动性。一个子样本（N=424）还在记录 EEG 的同时完成了 Go/No-Go 任务。
确定了四个具有不同情绪调节、威胁敏感性和冲动性水平的群体。与其他两个得分较低的群体相比，青少年比儿童更有可能处于高情绪调节/威胁敏感性或中度情绪调节/高冲动性群体中。高情绪调节/威胁敏感性组的 ERN 最大，而中度情绪调节/高冲动性组的 ERN 最小。ERN 可能是一种潜在的生物标志物，有助于区分可能面临焦虑或冒险风险的不同青少年群体。
