An exploration of metacognitive beliefs and thought control strategies in bipolar disorder

Abstract Background Metacognitive factors influence depression, but are largely unexplored in bipolar disorders. We examined i) differences in metacognitive beliefs and thought control strategies between individuals with bipolar disorder and controls, and ii) to what extent clinical characteristics were related to levels of metacognitive beliefs and thought control strategies in bipolar disorder. Method Eighty patients with bipolar disorder were assessed for age at onset of affective disorder, number of affective episodes, symptoms of mania and depression, metacognitive beliefs (MCQ-30) and thought control strategies (TCQ). Control subjects (N = 166) completed MCQ-30 and TCQ. Factors impacting on metacognitive beliefs and thought control strategies were explored with multiple linear regressions. Results Patients with bipolar disorder reported higher levels of unhelpful metacognitive beliefs and thought control strategies than controls. Metacognitive beliefs were mainly influenced by depressive symptoms, and age at onset of affective illness. Thought control strategies were mainly influenced by metacognitive beliefs and age at onset of affective illness. Conclusion Our findings suggest that metacognitive beliefs and control strategies are relevant in bipolar disorder. Depression and age at onset of affective disorder could contribute to metacognitive beliefs in bipolar disorder, and influence the use of thought control strategies. This indicates potential relationships that warrant further investigation for clinical relevance.
