Developmental trajectory classes in psychological dysregulation predict later decision-making competence.

Area of Science:

• Developmental psychology
• Neuroscience
• Behavioral science

Background:

• Adolescence and emerging adulthood carry risks like substance use and antisocial behaviors.
• Psychological regulation, including emotional stability and impulse control, typically increases during this period.
• Individual differences in developmental trajectories of psychological regulation are significant.

Purpose of the Study:

• To investigate how heterogeneous developmental trajectories of psychological regulation relate to decision-making competence.
• To identify distinct patterns of psychological regulation development from childhood through emerging adulthood.
• To assess the association between these developmental patterns and decision-making skills.

Main Methods:

• Longitudinal assessment of psychological regulation from ages 10-12 through 19.
• Administration of the Youth Decision-Making Competence (DMC) measure at age 19.
• Latent class growth mixture modeling to identify distinct developmental trajectories of psychological dysregulation.

Main Results:

• Lower psychological regulation in childhood correlated with lower decision-making competence.
• Three distinct trajectory classes emerged: Moderate-Stable, Low-Decreasing, and High-Increasing dysregulation.
• The High-Increasing dysregulation group showed significantly lower decision-making competence compared to other groups.

Conclusions:

• Early patterns of psychological dysregulation can predict later decision-making abilities.
• Individual differences in developmental trajectories highlight the heterogeneity of adolescent psychological growth.
• Understanding these trajectories is crucial for interventions aimed at improving decision-making skills and reducing risk behaviors.
