为探究自尊与社交焦虑的关系,以及正性评价恐惧在其中的作用机制,采用自尊量表、正性评价恐惧量表、社会焦虑量表对389名大学生进行调查。结果表明:1) 自尊能够负向预测大学生社交焦虑。2) 正性评价恐惧在自尊与社交焦虑之间起中介作用。结果揭示了自尊影响社交焦虑的内在机制,对于大学生社交焦虑的干预提供了一定的理论依据。To explore the relationship between self-esteem and social anxiety, and the mediating role of fear of positive evaluation, a survey was administered to 389 college students using the Self-Esteem Scale, Fear of Positive Evaluation Scale and Interaction Anxiousness Scale. The findings revealed that: 1) Self-esteem negatively predicted college students’ social anxiety. 2) Fear of positive evaluation had a mediated effect on self-esteem and social anxiety. This study elucidates the mechanism by which self-esteem influences college students’ social anxiety, offering important implications for targeted interventions aimed at enhancing college students’ social anxiety.
