The present study aimed to examine multidimensional factors that contribute to a poor performance in a public speaking task. An adapted version of the Trier Social Stress Test (TSST) as used to elicit psychosocial stress among 43 university students and multidimensional assessments were involved to investigate acute stress responses by psychological measures (i.e. personality, affect, appraisal, coping), physiological measures (i.e. cortisol; Dehydroepiandrosterone: DHEA; ratio of cortisol/DHEA) and behavioural measures (voice, postural control). Our results showed that psychological factors seemed to be the most sensitive to stress performance. A mediation effect was detected between psychological factors and objective performance. Cortisol to DHEA ratio also showed to be associated with speaking performance. This study added evidence to the literature with regards to a multidimensional way to study human stress response and may help individuals use functional coping to improve their performance and better adapt to stressful situations.
