Sex differences in the development of physical aggression: An intergenerational perspective and implications for...

Area of Science:

• Developmental Psychology
• Behavioral Genetics
• Public Health

Background:

• Chronic physical aggression (CPA) is a significant developmental concern.
• Understanding its early onset and intergenerational transmission is crucial for effective intervention.
• Sex differences in aggression patterns require specific consideration.

Purpose of the Study:

• To review current knowledge on the development of CPA.
• To identify effective prevention strategies for CPA.
• To examine the role of intergenerational transmission and biopsychosocial factors.

Main Methods:

• Systematic review of research on CPA development over the past three decades.
• Analysis of genetic and epigenetic influences on behavior.
• Examination of long-term developmental trajectories.

Main Results:

• Evidence supports a long-term, biopsychosocial developmental approach to CPA prevention.
• Genetic and environmental factors influence gene expression from conception.
• Early intervention and support are critical for breaking the cycle.

Conclusions:

• Preventing CPA necessitates an intergenerational perspective and long-term support.
• Targeted support for pregnant women with behavioral issues, their partners, and offspring can disrupt transmission.
• A comprehensive biopsychosocial model is essential for addressing CPA.
