The Portuguese Pubertal Development Scale (PDS) is a useful self-assessment tool for tracking pubertal progression in adolescents. It correlates well with the Tanner scale, making it reliable for large-scale studies in Brazil.
Area of Science:
- Adolescent Medicine
- Developmental Pediatrics
- Public Health
Background:
- Pubertal development assessment is crucial for monitoring adolescent health.
- The Tanner scale is the gold standard for clinical assessment of puberty.
- Self-assessment tools can offer a practical alternative for large-scale studies.
Purpose of the Study:
- To validate the Portuguese version of the Pubertal Development Scale (PDS) against the Tanner scale.
- To assess the reliability of the PDS for measuring pubertal progression in Brazilian adolescents.
Main Methods:
- Cross-sectional study of 133 children and adolescents (ages 9-17).
- Participants completed the Portuguese PDS and underwent clinical examination by adolescent medicine specialists.
- Statistical analysis included correlation and intra-class correlation coefficients.
Main Results:
- Modest exact agreement between PDS and Tanner scale, but significant associations found.
- PDS scores adequately reflected pubertal changes and correlated with Tanner staging.
- Confirmatory Factor Analyses showed excellent fit indices for PDS latent factors.
Conclusions:
- The Portuguese PDS is a useful and reliable self-assessment instrument for estimating pubertal progression.
- It is suitable for large-scale studies in Brazil investigating adolescent health and pubertal development.
- Exact agreement with clinical staging is not essential for its utility.
