Summary
Early anxiety predicts later depression in adolescents, with avoidance behaviors partially explaining this link. Experiencing trauma did not alter the relationship between avoidance and depression.
Area of Science:
- Psychology
- Psychiatry
- Longitudinal Studies
Background:
- Anxiety and depression are frequently comorbid conditions.
- Understanding the longitudinal pathways between anxiety and depression is crucial for effective interventions.
Purpose of the Study:
- To investigate the longitudinal relationship between adolescent anxiety and later depression.
- To examine the mediating role of avoidance behaviors.
- To explore the moderating effect of trauma on this relationship.
Main Methods:
- Longitudinal study with N=6504 adolescents.
- Baseline measures of anxiety and depression.
- Follow-up measures of avoidance (1 year), trauma (6-8 years), and depression (12-14 years).
- Structural equation modeling analysis.
Main Results:
- Adolescent anxiety significantly predicted depression over 12-14 years later.
- Avoidance behaviors partially mediated the relationship between earlier anxiety and later depression.
- Trauma did not moderate the association between avoidance and depression.
Conclusions:
- Anxiety may contribute to the development of depression in adolescents through avoidance.
- The pathway from anxiety to depression via avoidance appears robust, irrespective of trauma exposure.

Social anxiety disorder, also known as social phobia, is characterized by an intense fear of social situations where one might face humiliation, rejection, embarrassment, or negative evaluation. This disorder leads individuals to avoid activities like casual conversations, public speaking, or seemingly simple tasks such as eating, signing documents, or swimming, in public settings.
