SUMMARY:

Background and Objectives: This study aims to evaluate changes in the skin electrodermal activity in a situation of induced acute stress in a population that is regularly exposed to chronic stress. Methods: Undergraduate students of healthcare courses were submitted to the Trier Social Stress Test (TSST). They filled out the State-Trait Anxiety Inventory Form-Y (STAI) and questions about school life and lifestyle before the TSST. Stress reactivity was evaluated by the Galvanic Skin Response (GSR) and by a Visual Analog Scale (VAS). Results: Students with ages ranging from 18 to 25 years participated (n=52, 75% females). The mean STAI score was 44.50 ± 9.74 (mean ± SD). TSST increased both GSR values and VAS scores in the participants. The overall GSR went from an average of 2.68 ± 2.26 µS to 5.35 ± 3.46 µS and VAS score from 4.63 ± 2.14 to 5.80 ± 2.01. A negative correlation between the magnitude of responses obtained by GSR and VAS was observed. There was no difference between both hemispheres of the wave on the EEG examination when compared with the left and right sides or after the TSST (p = 0.127 and p = 0.082 in the Wilcoxon signaling test, alpha). Soon after the TSST, an increase in alpha wave amplitude was identified in the low anxiety group (p = 0.007); (p = 0.073 in the moderate anxiety group and p = 0.310 in the high anxiety group) (Wilcoxon test vs. after TSST). Conclusions: A substantial number of students reported moderateto-high anxiety. The magnitude of the stress response was unrelated to the participants’ anxiety level. Participants who reported a larger stress reactivity on VAS tended to show a smaller variation in GSR. No EEG examination was identified that there was a significant difference after stress and also when compared to the low-medium and high-anxiety groups.
