BACKGROUND: Maladaptive metacognitive beliefs concerning the uncontrollability and danger of negative thinking (MCQ-NEG) were associated with suicidal ideation (SI) in major depressive disorder (MDD). The present study investigated whether metacognitive beliefs were different between groups and whether metacognitive beliefs explained incremental variance in suicidal ideation. METHODS: One hundred sixty-seven patients with MDD were recruited along with 170 healthy controls. Metacognitive beliefs and suicidal ideation were assessed using the Metacognition Questionnaire-30 Items (MCQ-30) and Beck Scale for Suicide Ideation (BSSI), separately. Group differences were assessed using t tests. The associational variable analysis was carried out to test the association between variables in MDD. RESULTS: (1) The MDD exhibited higher levels of maladaptive metacognitive beliefs. (2) Patients who had attempted suicide showed a higher level of MCQ-NEG compared to those with suicidal ideation alone. (3) MCQ-NEG explained incremental variance between depression severity and suicidal ideation when covariates are controlled in MDD. CONCLUSIONS: This study suggested that maladaptive metacognitive beliefs distinguished suicidal patients from non-suicidal patients, and the metacognitive model appeared relevant to suicidal ideation.
