Symptoms Moderating the Association Between Recent Suicide Attempts and Trauma Levels: Fan-Shaped Effects.

Area of Science:

• Psychiatry
• Psychology
• Public Health

Background:

• Trauma exposure is a significant risk factor for suicide attempts.
• Understanding moderating variables is crucial for developing effective suicide prevention strategies.
• Previous research has explored various risk factors, but the moderating role of specific symptoms requires further investigation.

Purpose of the Study:

• To identify symptoms that moderate the incidence of recent suicide attempts in a large French community sample.
• To examine the pattern of these moderating symptoms in relation to trauma levels.
• To investigate how the presence or absence of these symptoms influences suicide attempt risk.

Main Methods:

• A large community sample of 39,617 French citizens was analyzed.
• Five trauma levels were established using posttraumatic stress disorder items from the Mini International Neuropsychiatric Interview.
• Twenty-three potential moderating symptoms were examined for a fan-shaped pattern.

Main Results:

• Seven specific symptoms demonstrated a fan-shaped moderating pattern.
• These symptoms included desire for death, self-harm intention, suicidal ideation, lifetime suicide attempt, depressed mood, loss of interest, and panic attack.
• The absence of these symptoms was associated with a decreased incidence of suicide attempts, while their presence correlated with a gradual increase.

Conclusions:

• Specific symptoms significantly moderate suicide attempt incidence, acting as key indicators of risk.
• The identified symptoms can inform targeted interventions for individuals at risk of suicide.
• Public health strategies should consider these moderating symptoms in suicide prevention efforts within trauma-exposed populations.
