Hypothesis
Executive dysfunction would predict both reactive and proactive aggression, with impulsivity mediating these relationships.
Conclusion
Executive dysfunction contributes to adolescent aggression both directly and indirectly through increased impulsivity, with sex differences observed in the effects.
Supporting Evidence
- Executive dysfunction at T1 significantly predicted both proactive and reactive aggression at T2.
- Impulsivity at T2 partially mediated the relationship between executive dysfunction at T1 and both types of aggression at T2.
- Sex moderated the relationship between impulsivity and aggression, with stronger effects observed in males.
Takeaway
This study found that when teenagers have trouble with executive functions, they are more likely to act aggressively, especially if they are impulsive. Boys are more affected by this than girls.
Methodology
A longitudinal design with a 1-year follow-up was employed, involving self-report questionnaires from middle school students.
Potential Biases
Potential subjective bias due to reliance on self-reported data.
Limitations
The study did not account for environmental factors like parental influence and peer relationships, and relied on self-reported data.
Participant Demographics
617 middle school students, mean age 15.26 years, 59% male.
