Rethinking Suicidal Behavior Disorder.

Area of Science:

• Psychiatry
• Mental Health Diagnostics
• Clinical Psychology

Background:

• Suicidality is the leading cause of psychiatric mortality.
• Currently, no formal diagnosis exists for suicidality.
• Suicidal Behavior Disorder (SBD) is proposed in DSM-5 as a condition for further study.

Purpose of the Study:

• To stimulate discussion on classifying suicidality as a diagnosable psychiatric condition.
• To evaluate the clinical utility of the proposed Suicidal Behavior Disorder (SBD).
• To propose revised diagnostic criteria for SBD.

Main Methods:

• Review of pragmatic and conceptual rationales for diagnosing suicidality.
• Analysis of the current SBD's limitations in clinical practice.
• Re-conceptualization of SBD from a descriptive psychiatry perspective.

Main Results:

• The current SBD offers limited clinical utility for assessing symptoms, planning treatment, or monitoring progress.
• A revised SBD is hypothesized as an independent, episodic, and often co-occurring condition.
• New cognitive, affective, and behavioral criteria are proposed to capture suicidality's phenomenology.

Conclusions:

• The revised SBD serves as a foundation for debating whether significant suicidality constitutes a mental illness.
• Further dialogue is needed to define the essential features of a diagnosable suicidality disorder.
• Improved diagnostic criteria can enhance clinical management of suicidal conditions.
