Self-related constructs feature prominently in cognitive models of both social anxiety and depression. However, few studies have simultaneously investigated the unique relationship between self-related constructs and social anxiety and depression, while also controlling for the association between the two variables. In the present study, 522 undergraduate students completed measures of maladaptive self-beliefs, self-esteem, self-criticism, self-focused attention, self-concept clarity, social comparison, and social anxiety and depression. Bivariate correlations demonstrated that self-related constructs not only significantly correlated with social anxiety but also with depression and other self-variables. When entered simultaneously, multiple regression analyses indicated that maladaptive self-beliefs were uniquely and positively associated with social anxiety and depression, while self-esteem and self-concept clarity were uniquely and negatively associated with social anxiety and depression. A unique positive association between private self-consciousness and depression was also found. Maladaptive self-beliefs and self-esteem were the constructs most strongly associated with social anxiety and depression respectively. These findings underscore the importance of a negative self-concept even in subclinical presentations and suggest that several key self-related constructs may represent transdiagnostic vulnerability factors linking social anxiety and depression. Future research should continue to uncover unique relationships between self-related variables and social anxiety and depression in both clinical and non-clinical samples.

非临床样本中自相关结构、社交焦虑和抑郁之间的独特关系

自我相关的结构在社交焦虑和抑郁的认知模型中都占有重要地位。然而，很少有研究同时调查自我相关结构与社交焦虑和抑郁之间的独特关系，同时还控制了这两个变量之间的关联。在本研究中，522 名本科生完成了适应不良的自我信念、自尊、自我批评、自我关注、自我概念清晰、社会比较以及社交焦虑和抑郁的测量。双变量相关性表明，自我相关的结构不仅与社交焦虑显着相关，而且与抑郁和其他自变量显着相关。同时输入时，多元回归分析表明，适应不良的自我信念与社交焦虑和抑郁呈独特且正相关，而自尊和自我概念清晰与社交焦虑和抑郁呈独特且负相关。还发现私人自我意识与抑郁之间存在独特的正相关关系。适应不良的自信心和自尊分别是与社交焦虑和抑郁最密切相关的结构。这些发现强调了即使在亚临床表现中消极自我概念的重要性，并表明几个关键的自我相关结构可能代表了将社交焦虑和抑郁联系起来的跨诊断脆弱性因素。
