Fears related to COVID-19 (“coronavirus fears”) have emerged as a new psychological effect of the current COVID-19 pandemic and have been associated with psychological distress and impairment. Other adverse effects include an increase in anxiety and depression symptoms and the respective disorders. The purpose of the current study was to examine the incremental validity of coronavirus fears and transdiagnostic factors in the prediction of the severity of anxiety and depressive disorder symptoms. A sample of 144 adolescents (aged 12-18 years) most of whom showed elevated levels of anxiety and depressive disorder symptoms completed several self-report measures online assessing coronavirus fears, transdiagnostic vulnerability and protective factors, and emotion regulation strategies. Results based on a series of hierarchical multiple regression analyses revealed that coronavirus fears, negative affect, intolerance of uncertainty, acceptance/tolerance, rumination and suppression explained unique variance in the severity of anxiety and depressive disorder symptoms. Path analysis demonstrated that acceptance/tolerance, rumination and suppression mediated the association between higher level transdiagnostic factors and the severity of major depressive disorder symptoms. Findings provide support for the hierarchical transdiagnostic model of emotional disorders (Sandín, Chorot et al., 2020) and suggest that clinicians should be aware of coronavirus fears. Also, the results warrant the need to consider transdiagnostic vulnerability and protective processes in the new protocols for the treatment of emotional disorders.

冠状病毒恐惧对临床和亚临床青少年焦虑和抑郁症症状的影响：负面情绪、对不确定性的不容忍和情绪调节策略的作用

与 COVID-19 相关的恐惧（“冠状病毒恐惧”）已成为当前 COVID-19 大流行的新心理影响，并与心理困扰和损害相关。其他副作用包括焦虑和抑郁症状以及相应疾病的增加。当前研究的目的是检验冠状病毒恐惧和跨诊断因素在预测焦虑和抑郁症症状严重程度方面的增量有效性。144 名青少年（12 至 18 岁）为样本，其中大多数表现出较高水平的焦虑和抑郁症症状，他们完成了多项在线自我报告措施，评估对冠状病毒的恐惧、跨诊断脆弱性和保护因素以及情绪调节策略。基于一系列分层多元回归分析的结果显示，冠状病毒的恐惧、负面影响、对不确定性的不容忍、接受/容忍、沉思和抑制解释了焦虑和抑郁症症状严重程度的独特差异。路径分析表明，接受/容忍、沉思和抑制介导了较高水平的跨诊断因素与重度抑郁症症状严重程度之间的关联。研究结果为情绪障碍的分层跨诊断模型提供了支持（Sandín、Chorot 等人，2020），并建议临床医生应该意识到对冠状病毒的恐惧。此外，研究结果表明，在治疗情绪障碍的新方案中需要考虑跨诊断的脆弱性和保护过程。
