Negative affect and hormone levels in young adolescents: Concurrent and predictive perspectives

Area of Science:

• Developmental Psychology
• Endocrinology
• Adolescent Health

Background:

• Negative affect, including anxiety and depressive symptoms, is common in adolescents.
• Puberty involves significant hormonal changes from gonadal and adrenal sources.
• Understanding the interplay between psychological states and hormonal shifts is crucial for adolescent well-being.

Purpose of the Study:

• To investigate the relationship between negative affect and gonadal/adrenal hormones in young adolescents.
• To examine the stability of negative affect over a one-year period.
• To explore how hormonal changes during puberty influence emotional states.

Main Methods:

• Longitudinal study with three assessments over one year in 56 boys and 52 girls (ages 9-14).
• Measured serum hormone levels (gonadotropins, gonadal steroids, adrenal androgens, cortisol) and pubertal development (Tanner criteria).
• Assessed negative affect via self-report (anxiety, depression) and mother reports (internalizing behaviors).

Main Results:

• Cross-sectionally, higher negative affect in boys correlated with advanced pubertal stage, older age, and lower testosterone, cortisol, and dehydroepiandrosterone sulfate levels.
• Longitudinally, initial negative affect and, to a lesser extent, hormone levels predicted negative affect 12 months later.
• Evidence suggests a bidirectional relationship between negative affect and hormonal changes during puberty.

Conclusions:

• Puberty-related hormone levels are significant factors in the development of negative affect.
• Psychological characteristics and hormonal profiles should be jointly considered to understand adolescent emotional development.
• This research provides insights into the complex biological and psychological processes during adolescence.
