The Gratitude Questionnaire (GQ-6).
The gratitude questionnaire is, in this instance, a 6 item questionnaire involving how individuals experience gratitude in their daily life.
Items are scored on a 1-7 scale, with the total scale score calculated as a sum of the items.
Some items are reversed. For example, a score of 1 would become a score of 7.
