Stress and Internalizing Problems in Adolescents: A Dynamic Longitudinal Analysis.

Area of Science:

• Psychology
• Adolescent Development
• Mental Health Research

Background:

• Internalizing problems often increase in adolescence, but the stress-symptom relationship is not fully understood.
• The interplay between stress and internalizing symptoms requires clarification regarding causality.

Purpose of the Study:

• To determine if stress and internalizing symptoms have a bidirectional effect over time.
• To differentiate stable individual differences from dynamic within-person processes in this relationship.

Main Methods:

• A longitudinal study of 1618 adolescents (mean age 16.3) assessed over 6-month intervals.
• Utilized the Random Intercept Cross-Lagged Panel Model (RI-CLPM) to analyze stable versus fluctuating effects.
• Measured subjective stress, emotional problems, and peer problems.

Main Results:

• Strong association found between subjective stress and emotional problems; weaker link with peer problems.
• The majority of these associations were explained by stable, trait-like individual differences.
• No significant time-ordered effects were observed at the within-person level.

Conclusions:

• The link between adolescent stress and internalizing symptoms is primarily due to stable, dispositional factors (e.g., personality traits).
• Findings do not support stress sensitization or generation hypotheses but align with diathesis-stress models.
• Interventions should focus on enhancing emotional regulation and resilience to address underlying vulnerabilities.
