Per procedural anxiety, measured by the Spielberger Anxiety State Inventory in French (Gauthier and Bouchard, 1993).

The Spielberger Anxiety State Inventory is a self questionnaire of 20 items, each item scores from 1 to 4. The result of the test is the sum of the 20 items, therefore the result ranges from 20 to 80. A high score is related to a high level of anxiety at the moment of the test.

Per procedural pain, measured by the visual analog pain scale. The visual analog pain scale rates pain from 0 to 10, 0 being the least pain imaginable and 10 the maximal pain imaginable.
