Abstract

Objective: The Trail Making Test (TMT) and Stroop Test (ST) are attention tests widely used in clinical practice and research. The aim of this study was to provide normative data for the adult Brazilian population and to study the influence of gender, age and education on the TMT parts A and B, and ST cards A, B and C.

Methods: We recruited 1447 healthy subjects aged ≥18 years with an educational level of 0-25 years who were native speakers of Portuguese (Brazilian). The subjects were evaluated by the Matrix Reasoning and Vocabulary subtests of the Wechsler Adult Intelligence Scale-III, along with the TMTA, TMTB and ST A, B and C.

Results: Among the participants, mean intellectual efficiency was 103.20 (SD: 12.0), age 41.0 (SD: 16.4) years and education 11.9 (SD: 5.6) years. There were significant differences between genders on the TMTA (p=0.002), TMTB (p=0.017) and STC (p=0.024). Age showed a positive correlation with all attention tests, whereas education showed a negative correlation. Gender was not found to be significant on the multiple linear regression model, but age and education maintained their interference.

Conclusion: Gender did not have the major impact on attentional tasks observed for age and education, both of which should be considered in the stratification of normative samples.

Objetivo: Os testes de atenção Trail Making Test (TMT) e Stroop Test (ST) são largamente usados na prática clínica e em pesquisas. O objetivo deste estudo foi fornecer informação normativa para a população brasileira de adultos e estudar a interferência de gênero, idade e educação no TMT parte A e B e no ST cartão A, B e C.

Métodos: Recrutamos 1447 sujeitos saudáveis com idade ≥18 anos, nível educacional de 0-25 anos, falantes nativos do Português (Brasil). Os sujeitos foram avaliados pelos subtestes do Wechsler Adult Intelligence Scale-III Raciocínio Matricial e Vocabulários, além do TMTA, TMTB e ST A, B e C.

Resultados: Entre os participantes a média de eficiência intelectual foi de 103,20 (SD: 12,0), de idade 41,0 (SD: 16,4) anos e de escolaridade 11,9 (SD: 5,6) anos. Houve diferenças significantes por gênero em TMTA (p=0,002), TMTB (p=0,017) e STC (p=0,024). Idade se correlacionou de modo positivo com todos os testes de atenção, enquanto a escolaridade correlacionou-se de modo negativo. Após o modelo de regressão linear múltipla o gênero não manteve correlação significativa, mas idade e escolaridade mantiveram sua interferência.

Conclusão: O gênero não mostrou grande impacto nas tarefas atencionais como a idade e escolaridade que devem, portanto, ser consideradas na estratificação de amostras normativas.

Keywords: Stroop test; Trail Making Test; attention; demographic analysis.
