Trial outcomes

Primary outcomes

1

Anxiety behavior in Virtual Reality

Using different scenes in Virtual Reality, parameters of motion behavior such as speed (measured in meters per second) and distance walked (measured in meters) will be assessed using motion tracking technology. These measurements will be combined to generate a composite score of anxiety-related motion behavior.

Time frame
on day 8 of each intervention arm (visit 2 and 4)
2

Risk propensity on a decision-making task

The choice (accept/reject) between a risk/gamble or safe option, based on a task paradigm by Liu et al. (2021)

Time frame
on day 8 of each intervention arm (visit 2 and 4)
3

Competitive confidence in a competition task

based on a task paradigm by Goette et al., 2015

Time frame
on day 8 of each intervention arm (visit 2 and 4)
4

Delay Discounting behavior in a computerized task

based on a task paradigm by Eisenstein et al. 2015

Time frame

Secondary outcomes

1

Gut microbiome

Assessed via stool samples after each intervention

Time frame
on day 8 of each intervention arm (visit 2 and 4)

Daily food intake

Self-reported food intake recorded via FoodApp or handwritten food diary

Time frame
