Understanding suicidal behavior and gender-specific pathways in an adolescent community sample: a structural model...

Area of Science:

• Psychiatry
• Developmental Psychology
• Public Health

Background:

• Adolescent suicide is a critical public health issue requiring improved risk assessment.
• Understanding motivational and volitional factors is key to developing effective prevention strategies.

Purpose of the Study:

• To examine emotional abuse, non-suicidal self-injury (NSSI), impulsivity, and emotional symptoms as predictors of suicidal ideation and attempts in adolescents.
• To investigate potential sex-based differences in these risk factor associations.

Main Methods:

• A community-based sample of 1,526 adolescents (ages 12-16) in Madrid, Spain, was analyzed.
• A Multiple Indicators and Multiple Causes (MIMIC) structural equation model (SEM) was employed.
• Good model fit was achieved (CFI=.96, TLI=.97, RMSEA=.078, SRMR=.061).

Main Results:

• Emotional symptoms and emotional abuse significantly predicted suicidal ideation.
• NSSI and higher ideation intensity strongly predicted suicide attempt probability.
• Gender did not moderate risk factor associations, but females showed greater impact from emotional abuse and symptoms.

Conclusions:

• Emotional symptoms and abuse are key risk factors for adolescent suicidal ideation.
• NSSI and ideation intensity are critical for predicting suicide attempts.
• Prevention strategies must be comprehensive, addressing universal and gender-specific risks for adolescent suicide.
