Does worry moderate the relation between aggression and depression in adolescent girls?

Area of Science:

• Psychology
• Developmental Psychology
• Clinical Psychology

Background:

• Aggressive girls face higher depression risks than aggressive boys.
• The interplay between aggression and depression in girls requires further investigation.
• Worry is hypothesized to influence the link between aggression and depressive symptoms.

Purpose of the Study:

• To investigate worry as a moderator between peer-nominated aggression and self-reported depressive symptoms in adolescent girls.
• To differentiate the moderating role of worry based on the type of aggression (physical vs. relational).

Main Methods:

• Longitudinal study of 226 girls aged 13 at Time 1.
• Peer nominations assessed aggression.
• Self-report questionnaires measured depressive symptoms and worry.
• Statistical analysis examined worry as a moderator.

Main Results:

• Worry significantly exacerbated depressive symptoms in physically aggressive girls concurrently and at one-year follow-up.
• Worry did not moderate the relationship between relational aggression and depressive symptoms.
• The impact of worry on depression varied depending on the form of aggression.

Conclusions:

• Worry is a critical factor in predicting depression among aggressive adolescent girls.
• The moderating effect of worry is specific to the manifestation of aggression, particularly physical aggression.
• Findings underscore the importance of addressing worry in interventions for aggressive girls at risk for depression.
