Predicting Patterns of Intimate Partner Violence Perpetration From Late Adolescence to Young Adulthood

Area of Science:

• Psychology
• Developmental Psychology
• Criminology

Background:

• Longitudinal patterns of psychological and physical intimate partner violence (IPV) have been identified.
• Previous research has established distinct patterns of IPV perpetration, ranging from active to minimal aggression.

Purpose of the Study:

• To examine theory-derived variables predicting membership in identified IPV patterns.
• To investigate the roles of interparental aggression, social-information processing (SIP) biases, relationship insecurities, and relationship discontinuity in IPV perpetration.

Main Methods:

• Utilized multinomial logistic regression analysis.
• Analyzed data from 484 participants across eight waves (ages 18-25).
• Examined predictors of psychological and physical IPV patterns.

Main Results:

• SIP biases, preoccupied insecurity, and less relationship discontinuity predicted actively aggressive psychological IPV.
• SIP biases and less relationship discontinuity differentiated extensively aggressive psychological IPV from minor aggression patterns.
• Interparental aggression, SIP biases, and relationship insecurities predicted physical IPV.

Conclusions:

• Developmental patterns of IPV are predictable by social and psychological factors.
• Findings contribute to developmental theory and inform interventions for IPV.
• Social-information processing and relationship dynamics are key factors in understanding IPV perpetration.
