Outcome Measures

Primary Outcome Measures

Affect [Change from baseline affect after 90 minutes.]
The Spanish adaptation of the Positive and Negative Affect Schedule will be utilised. Participants rate how they feel at the present moment on a five-point Likert scale, where "not at all or very slightly" is scored as 1 and "a lot" as 5. Scores of two 10-item subscales will be analysed separately in the analysis, labelled either as Positive Affect or Negative Affect. Higher scores in the Positive Affect subscale represent higher levels of positive affect and lower scores in the Negative Affect subscale represent lower levels of negative affect.
Subjective Vitality [Change from baseline subjective vitality after 90 minutes.]
The 6-item Spanish adaptation of the Subjective Vitality Scale will be utilised. Participants will transmit their levels of energy and aliveness at the present moment by rating the items on a seven-point Likert scale where 1 stands for "Not true at all" and 7 "Very true". The scores for each item will be summed up for statistical analyses. Higher scores indicate higher levels of energy and aliveness feeling.
