摘要
Purpose: Anxiety and depressive disorders frequently occur in people with epilepsy (PWE). An information processing model of psychopathology, the Self-Regulatory Executive S-REF) model specifies that maladaptive metacognitive beliefs and processes play a fundamental role in the development and maintenance of anxiety and depression. This study explored whether metacognitive beliefs would explain additional variance in anxiety and depression after accounting for demographics, physical and/or psychiatric illnesses, epilepsy characteristics and medication issues. The mediational relationships between metacognitive beliefs, worry and anxiety and depression, predicted by the metacognitive model were also explored, Methods: Three hundred and forty-nine PWE participated in an online survey and completed self-report questionnaires measuring anxiety, depression, metacognitive beliefs and worry. Participants also provided information on epilepsy characteristics, demographics, comorbid physical and/or psychiatric illnesses, number of, and perceived side effects of, anti-epileptic medication. Results: Regression analysis showed that metacognitive beliefs were associated with symptoms of anxiety, depression, and explained additional variance in these outcomes after accounting for the control variables. Furthermore, the fundamental tenet of the metacognitive model was supported; the relationship between negative metacognitive beliefs about uncontrollability and danger of worry and anxious and depressive symptoms was partially mediated by worry. Conclusion: This is the first study to demonstrate that metacognitive beliefs and processes contribute to anxiety and depression beyond variables often associated with emotional distress in PWE. Further research is required to test if modification of metacognitive beliefs and processes using metacognitive therapy would effectively alleviate anxiety and depression in PWE.
