Does mental illness in adolescence/young adulthood predict intimate partner violence?

Area of Science:

• Psychiatry
• Public Health
• Criminology

Background:

• Intimate partner violence (IPV) is linked to poor mental health, with evidence suggesting a potential bidirectional relationship.
• Existing research primarily focuses on IPV causing mental health issues, with less attention on the reverse causality.

Purpose of the Study:

• To investigate whether poor mental health during adolescence and young adulthood predicts the occurrence of adult IPV.
• To examine the predictive relationship between mental health indicators in early life stages and later experiences of various forms of IPV.

Main Methods:

• Utilized longitudinal cohort study data, tracking participants from adolescence to adulthood.
• Assessed mental health using the Youth Self Report (YSR) at age 14 and the Young Adult Self Report (YASR) and Composite International Diagnostic Interview at age 21.
• Measured five forms of IPV (Severe Combined Abuse, Physical Abuse, Emotional Abuse, Harassment, Coercive Control) using the Composite Abuse Scale (CAS) at age 30.

Main Results:

• Delinquency and substance use disorders at age 21 significantly predicted all measured forms of IPV at age 30, even after adjusting for confounders.
• Specifically, substance use disorders predicted Severe Combined Abuse (OR 2.30), Physical Abuse (OR 1.67), and Coercive Control (OR 1.74).

Conclusions:

• Poor mental health, particularly substance use disorders and delinquency during adolescence and young adulthood, are significant predictors of adult intimate partner violence.
• Findings support the potential benefit of early intervention programs targeting mental health and substance use to prevent adult IPV.
