Rethinking Suicidal Behavior Disorder.

It is a peculiar fact that the deadliest psychiatric disturbance - suicidality - cannot be formally diagnosed. Suicidal behavior disorder (SBD), a condition for further study in the DSM-5, is the field's first attempt to capture suicidality in a diagnosis. To provoke discussion about the standing of suicidality as a diagnosable psychiatric condition. I present pragmatic and conceptual rationales for why a diagnosis of suicidality is clinically useful but conclude that SBD does little to aid clinicians in assessing suicidality's symptoms, planning treatment, or monitoring progress. To improve the clinical utility of SBD, I re-conceptualize it from the vantage point of descriptive psychiatry. I hypothesize that this revised SBD is an independent, episodic, and frequently co-occurring condition and propose new cognitive, affective, and behavioral criteria that more completely capture the phenomenology of suicidality. The revised SBD is a starting place for dialogue about whether a clinically significant presentation of suicidality is a mental illness and, if it is, what its defining features should be.
