Beschreibung

Virtual reality adaptations of the Trier Social Stress Test (TSST-VR)
constitute useful tools for studying the physiologic axes involved in
the stress response. Here, we aimed to determine the most appropriate
experimental approach to the TSST-VR when investigating the modulation
of the axes involved in the stress response. We compared the use of
goggles versus a screen projection in the TSST-VR paradigm. Forty-five
healthy participants were divided into two groups: the first one
(goggles condition; 13 females, 11 males) wore goggles while performing
the TSST-VR; the second (screen condition; 15 females, six males) was
exposed to the TSST-VR projected on a screen. Sympathetic reactivity to
stress was measured by continuously recording skin conductance (SC),
while the hypothalamic-pituitary-adrenal axis (HPA) was evaluated by
sampling salivary cortisol throughout the experiment. At the end of the
task, there was an increase in SC and cortisol level for both means of
delivering the TSST-VR, although the increase in SC was greater in the
goggles condition, while salivary cortisol was comparable in both
groups. Immersion levels were reportedly higher in the screen
presentation than in the goggles group. In terms of sex differences,
females experienced greater involvement and spatial presence, though
comparatively less experienced realism, than their male counterparts.
These findings help us determine which protocol of the TSST-VR is most
suitable for the stress response under study. They also emphasize the
need to consider the sex of participants, as males and females show
distinct responses in each protocol.
