Behavioral and functional aspects among public and private middle school students.
Maria Júlia Amaral Abranches de Almeida, Graziela Nunes Alfenas Fernandes, Stela Maris Aguiar Lemos
Behavioral difficulties in 11-to-14-year-old students were significantly linked to functional problems in stress management and social interaction.
More girls showed hyperactivity symptoms; more boys showed prosocial behavior difficulties. No significant link was found with school type or economic class.
Key findings
1Each SDQ behavioral scale (emotional symptoms, conduct problems, hyperactivity, peer problems, prosocial behavior) was significantly associated with one or more ICF functional codes covering stress management, basic and complex social interaction, and informal relationships.
2More girls than boys were classified with hyperactivity symptoms (p = 0.024), and more boys than girls showed prosocial behavior difficulties (p = 0.023).
3No significant associations were found between behavioral difficulties and whether students attended public or private school, or with their economic class.

What it does not show
Convenience sampling with no random selection; 79% of participants were from private schools and 64.5% were in the highest economic class, so the sample does not represent the broader adolescent population. Cross-sectional design: associations cannot be read as cause and effect. ICF codes were not independently assessed; they were derived from the SDQ responses, so the two measures share a common source. Only two performance qualifiers were used (no difficulty, unspecified difficulty), so the degree of functional limitation could not be captured. The SDQ is a caregiver-reported screening tool, not a diagnostic instrument, and it does not cover all psychosocial aspects of adolescence.

The easy way to misread this
Do not read the sex differences in hyperactivity and prosocial behavior as evidence of a biological gap between girls and boys. The sample was 79% private school and 64.5% highest economic class, the SDQ is a caregiver-reported screening tool rather than a diagnostic instrument, and the cross-sectional design cannot separate cause from correlation.
