Ítem único de autoeficacia académica: evidencias adicionales de validez con el modelo Big Five en estudiantes universitarios.

The aim of the study was to evaluate if the academic self-efficacy single-item (IUAA) has convergent validity by its relationship with the Big Five personality traits (5BF) in 450 university students (61.1% female; Mage=20.9; SDage=2.6) from a private college in Chiclayo (Peru). Besides the IUAA, we used the Big Five Inventory-15p (BFI-Sp) to assess the 5BF with 15 items (three items per factor). The research hypothesis was tested using a one-way ANOVA, with students' grouping according to their IUAA response. The results show conscientiousness as the trait with higher differences between groups, followed by openness and extraversion. Additionally, the groups do not differ substantially in agreeableness or neuroticism. Despite the limitations, the IUAA is an appropriate measure to assess academic self-efficacy in college students.
