Dynamic temporal relations between anxious and depressive symptoms across adolescence

Area of Science:

• Adolescent Psychology
• Developmental Psychology
• Clinical Psychology

Background:

• Anxiety and depression are common in adolescents, often co-occurring and impairing functioning.
• Previous research inconsistently linked adolescent depression to later anxiety.
• Understanding the dynamic interplay between these conditions is crucial for effective intervention.

Purpose of the Study:

• To examine the longitudinal, dynamic relationships between anxiety and depressive symptoms throughout adolescence.
• To investigate if maternal anxiety history, family relationship quality, or child's attributional style moderate the link between depressive and anxiety symptoms.

Main Methods:

• Longitudinal study with 240 children (mean age 11.86) and their mothers, assessed annually for 6 years.
• Children self-reported depressive symptoms; mothers reported on their child's anxiety symptoms.
• Dynamic latent change score models were used to analyze symptom trajectories.

Main Results:

• Adolescent anxiety symptoms consistently predicted increased depressive symptoms over time.
• Depressive symptoms predicted subsequent anxiety increases only in adolescents with a maternal history of anxiety, poor family relationships, or negative attributional styles.
• These findings highlight the complex, bidirectional nature of anxiety and depression in adolescence.

Conclusions:

• Anxiety is a robust predictor of future depressive symptoms in adolescents.
• Contextual factors (family environment) and individual characteristics (attributional style, maternal history) significantly influence the relationship between adolescent depression and subsequent anxiety.
• Targeting these moderators may be key for preventing comorbid anxiety and depression.
