心理灵活性与负性认知加工偏向：错失恐惧和自我损耗的链式中介作用

The Relationship between Psychological Flexibility and Negative Cognitive Processing Bias: The Chain Mediating Effect of Fear of Missing Out and Self-Depletion

摘要: 为探究心理灵活性与负性认知加工偏向的关系以及错失恐惧、自我损耗在二者之间的中介作用，采用接纳与行动问卷第二版、错失恐惧量表、自我调节疲劳量表、负性认知加工偏向量表等对550名大学生进行调查。结果表明：(1) 心理灵活性可以显著负向预测负性认知加工偏向；(2) 错失恐惧、自我损耗在心理灵活性与负性认知加工偏向之间均起到部分中介作用；(3) 错失恐惧和自我损耗在心理灵活性与负性认知加工偏向之间起链式中介作用。研究结果对改善大学生负性认知加工偏向，以及提高大学生心理健康水平具有一定的启示意义。

Abstract: To explore the relationship between psychological flexibility and negative cognitive processing bias, and the mediating role of fear of missing out and self-depletion between them, a sample of 588 postgraduate students were recruited to complete the questionnaires on the Acceptance and Action Questionnaire-Second Edition, the Fear of Missing Out Scale, the Self-Regulatory Fatigue Scale and the Negative Cognitive Processing Bias Scale. The results showed that: (1) psychological flexibility negatively predicts negative cognitive processing bias; (2) fear of missing out and self-depletion both played a partial mediating role between psychological flexibility and negative cognitive processing bias; (3) fear of missing out and self-depletion played a chain mediating role between them. The results provide suggestions for improving students’ negative cognitive processing bias and enhancing their mental health levels.
