The Relationship Between Negative Cognitive Styles and Lifetime Suicide Attempts is Indirect Through Lifetime Acute Suicidal Affective Disturbance Symptoms

摘要

Previous evidence suggests an association between negative cognitive styles and suicide-related outcomes. Recently, Acute Suicidal Affective Disturbance (ASAD) was proposed to characterize the phenomenology of acute suicidal crises, with key features being the rapid onset of suicidal intent, social- or self-alienation, perceptions of intractability, and overarousal. ASAD may account for the association between negative cognitive styles and suicide-related outcomes. Students (N=177) selectively recruited based on their history of suicidality completed self-report measures. ASAD symptoms explained the association between rumination subtypes (brooding and reflection), as well as anxiety sensitivity cognitive concerns, and lifetime number of suicide attempts. Further, ASAD symptoms significantly accounted for the relationship between a latent negative cognitive styles variable and lifetime number of suicide attempts. Together, these findings are consistent with theoretical conceptions of negative cognitive styles being an associated feature of ASAD, and that ASAD symptoms may account for the relationship between negative cognitive styles and suicidal behavior.
