Metacognitive model of suicidality: a study of Iranian inpatients

Résumé fourni par la source

Background: The metacognitive model of suicidality proposes that positive metacognitions about suicide activate suicide-specific rumination, which in turn leads to the activation of negative metacognitions about suicide and an escalating aggravation of suicidal ideation/behavior. Initial studies support the model assumptions. However, investigations in highly burdened inpatient samples as well as studies in non-Western samples are missing by now. Methods: = 11.04) took part in a cross-sectional assessment. Self-report measures to assess suicidal ideation/behavior, depressive symptoms, suicide-specific rumination, and metacognitions about suicide were used. Results: Positive metacognitions about suicide were associated with suicide-specific rumination. Suicide-specific rumination was associated with negative metacognitions about suicide. Suicidal thoughts were positively and positive metacognitions about suicide were negatively associated with lifetime suicide attempts. Conclusion: The results support assumptions of the metacognitive model of suicidality and underscore the importance of metacognitions about suicide and suicide-specific rumination in understanding the suicidal process.
