2.2.5. Mindfulness

Mindfulness reflects the propensity to be mindful in daily life (Heeren, Douilliez, Peschard, Debrauwere, & Philippot, 2011). It was assessed with the French version (Heeren et al., 2011) of the Five Facets Mindfulness Questionnaire (FFMQ) (Baer, Smith, Hopkins, Krietemeyer, & Toney, 2006), between January and June 2013. This validated questionnaire is composed of 39 items: 20 positively worded (e.g., “While walking, I am aware of the sensations in my body”) and 19 negatively worded (e.g., “I am easily distracted”) rated on a 5-points Likert scale ranging from 1 (never or very rarely true) to 5 (very often or always true). The score of the negative worded items were reversed before summing all items. This score was divided by the number of items, leading to a final overall score ranging from 1 (low degree of mindfulness) to 5 (high degree of mindfulness). The scale displayed good internal consistency (Cronbach's α = 0.89).
