The GAD-7 is a seven-point scale that is used to assess the level of anxiety and to assess the risk of developing generalized anxiety disorder (GAD). The questions included in the questionnaire concern the subjective assessment of anxiety, tension, nervousness, the ability to control emotions, the ease of their manifestation, and problems with relaxation The responses are rated on a 3-point Likert scale, where: 0 indicates not at all, 1—several days, 2—more than half the days, and 3—nearly every day. The assessment is based on the past 2 weeks. Scores 5, 10, and 15 are mild, moderate, and severe, respectively. Generalized anxiety disorder is likely if the sum of the points is at least 10 [20].
