Results. Significant associations were shown between anxiety (rs = -.119, p<.01), depression (rs = -.210, p<.01), emotional exhaustion (rs = -.352, p<.01), and alcohol consumption (rs = -.319, p<.01) with academic performance. The model showed that, anxiety (β = -.946, p <.05), depression (β = -1.711, p <.05), emotional exhaustion (β = -4.842, p <.05), and alcohol consumption (β = -2.519, p <.05) predict 46% of academic performance in nursing students.
