Resumen
Objetivo: Delinear el perfil de consumo de cafeína en estudiantes universitarios e investigar su asociación con el rendimiento en el control inhibitorio. Métodos: Estudio cuantitativo, observacional, analítico y transversal con 51 estudiantes de Medicina. Las expectativas sobre los efectos de la cafeína se evaluaron mediante el Brief CaffeineExpectancyQuestionnaire – Brazilian Version (B-CaffEQ-Br), y el control inhibitorio mediante la Puntuación de Interferencia de Golden del Stroop Color and Word Test (SCWT). Se realizaron análisis de correlación y comparaciones entre terciles. Resultados: La puntuación media del B-CaffEQ-Br fue de 77,8 ± 22,5 y la media de la Puntuación de Interferencia de Golden de 10,7 ± 8,96. No se observaron asociaciones significativas entre las expectativas sobre la cafeína y el control inhibitorio (Pearson: r = −0,234; p = 0,099; Spearman: ρ = −0,190; p = 0,182), ni diferencias entre terciles (ANOVA de Welch: F = 0,637; p = 0,535). Conclusión: Se observó una tendencia inversa entre las expectativas sobre la cafeína y el rendimiento cognitivo, sin significación estadística. No se evaluaron el consumo habitual ni la tolerancia individual.
