Influence of Screen Sizes on Responses to Visual Analog Scales of Stress

"An open questionnaire will be created by the Clinical Research Direction. The questionnaire will be opened by the examinator who will fulfill the anonymized identification of participants and the type of screens. In a dedicated room at the LaPSCo, the participants will answer the same VAS on four different sizes/types of screens (24-inch screen, laptop, tablet, smartphone) and on paper. Saliva will be collected after answering questionnaires. Heart rate variability and skin conductance will be measured with the use of a wrist watch during 15 minutes, from the entrance in the room to the completion of questionnaires.~The participant will undergo the same examination within a week (15 minutes)."
