Reseach progress in dual harm.

Area of Science:

• Psychiatry
• Clinical Psychology
• Forensic Psychology

Background:

• Self-harm and aggression frequently co-occur, a phenomenon termed dual harm.
• Dual harm may represent an independent behavioral pattern distinct from sole harm behaviors.
• High incidence of dual harm is observed in clinical and forensic populations.

Approach:

• Literature review to identify characteristics and influencing factors of dual harm.
• Analysis of existing theories explaining the mechanisms of dual harm.

Key Points:

• Individuals with dual harm exhibit earlier, more frequent, and broader harmful behaviors, including increased use of lethal methods.
• Common influencing factors include childhood adversities, emotional dysregulation, personality traits, mental disorders, and biological factors.
• A comprehensive theory for dual harm is still lacking, with current models including the two-stage model of countervailing forces and the cognitive-emotional model.

Conclusions:

• In-depth exploration of dual harm characteristics, influencing factors, and theories is vital for developing effective prevention strategies.
• Further research is needed to establish a comprehensive theoretical framework for dual harm.
• Understanding dual harm is critical for targeted interventions in clinical and forensic settings.
