Predictive factors for recurrent suicide attempts: Evidence from the ACTION-J study.

Area of Science:

• Psychiatry
• Public Health
• Epidemiology

Background:

• Suicide risk factors are well-researched, but predictors of suicide reattempts require further investigation.
• Understanding reattempt predictors is crucial for targeted interventions and suicide prevention strategies.

Purpose of the Study:

• To identify predictive factors for suicide reattempts among individuals who have already attempted suicide.
• To examine gender-specific predictors for suicide reattempts.

Main Methods:

• Analysis of data from the ACTION-J randomized controlled multicenter trial.
• Cox proportional hazards regression analysis used to examine predictive factors for recurrent suicide attempts.
• Patient characteristics extracted from baseline demographic and clinical data.

Main Results:

• A visit to a psychiatrist within one month of the suicide attempt was a significant predictor of reattempts in men (HR 2.49).
• For women, substance-related disorders (HR 3.65), previous suicide attempts (HR 2.28), and drug overdose during the first attempt (HR 1.82) were significant predictors.
• Drinking alcohol less than monthly was associated with a lower risk of reattempts in women (HR 0.42).

Conclusions:

• Early psychiatric consultation is a key factor in preventing suicide reattempts in men.
• Substance use disorders, prior suicide attempts, and initial drug overdose are critical indicators for suicide reattempt risk in women.
• These findings underscore the need for gender-tailored suicide prevention approaches.
