Externalizing problems and reward-punishment sensitivity: Testing within-person reciprocal associations in an...

Area of Science:

• Developmental Psychology
• Adolescent Behavior
• Temperament Research

Background:

• Temperament, particularly sensitivity to reward and punishment, is linked to adolescent externalizing problems.
• Reinforcement Sensitivity Theory (RST) posits that the behavioral activation system (BAS) and behavioral inhibition system (BIS) influence behavior based on reward and punishment.
• Previous research (Ramer et al., 2024) suggested reciprocal links between BAS/BIS sensitivity and oppositional/conduct problems.

Purpose of the Study:

• To replicate and examine the reciprocal relationships between BIS/BAS sensitivity and oppositional/conduct problems in a Norwegian adolescent sample.
• To investigate potential temperamental dispositions influencing different types of externalizing behaviors.

Main Methods:

• A longitudinal study of 2,147 Norwegian preadolescents (9 years old at baseline) over five annual measurement occasions.
• Utilized latent curve models with structured residuals to analyze reciprocal associations.
• Assessed temperament via behavioral activation system (BAS) and behavioral inhibition system (BIS) sensitivity.

Main Results:

• Replicated the vulnerability effect: increased BAS sensitivity predicted subsequent increases in oppositional problems.
• Replicated the scar effect: increased conduct problems predicted subsequent decreases in BIS sensitivity.
• Did not replicate the reverse pathways: oppositional problems did not predict BAS sensitivity, nor did BIS sensitivity predict conduct problems.

Conclusions:

• Results suggest that temperamental dispositions like BAS and BIS sensitivity may differentially influence oppositional and conduct problems.
• The findings partially support RST's predictions regarding temperament and externalizing behaviors in adolescents.
• Differences from prior research highlight the complexity of these relationships and warrant further investigation into moderating factors.
