About this trial
Visual analog scales (VAS) are one of the most common tools used in questionnaires. VAS are validated for pain and stress for example on a horizontal, non-calibrated line of 100 mm, ranging from very low (0) to very high (100). Nowadays, most VAS are used on questionnaires on internet. However, the influence of screen sizes on responses to visual analog scales were never studied.
