Adolescent friendships with deviant peers, stemming from coercive parenting, predict adult internalizing and externalizing symptoms. This association disrupts peer relationship development, impacting long-term adjustment.
Area of Science:
- Developmental Psychology
- Adolescent Psychology
- Social Psychology
Background:
- Adolescent peer associations are critical for development.
- Coercive parent-teen interactions may influence peer group selection.
- The long-term impact of deviant peer association requires further investigation.
Purpose of the Study:
- To examine the origins of adolescent association with deviant friends.
- To investigate the links between deviant peer association and functional difficulties into adulthood.
- To understand how coercive parenting influences these pathways.
Main Methods:
- Longitudinal study tracking 184 adolescents from age 13 to 27.
- Collateral data collected from friends, classmates, and parents.
- Statistical analyses controlled for adolescent delinquent behavior.
Main Results:
- Coercive parent-teen interactions predicted association with deviant friends.
- Deviant peer association was linked to declining peer functioning in adolescence.
- Association predicted greater adult internalizing/externalizing symptoms and poorer adjustment.
Conclusions:
- Deviant peer association, rooted in coercive parenting, disrupts peer relationship development.
- These disruptions have lasting implications beyond deviancy training.
- Interventions targeting parent-teen interactions may mitigate negative peer influences.
