The GAD-7 is used as rapid screening for the presence of a clinically significant anxiety disorder (GAD, PD, SP & PTSD), especially in outpatient settings. The GAD-7 score is calculated by assigning scores of 0, 1, 2, and 3, to the response categories of “not at all,” “several days,” “more than half the days,” and “nearly every day,” respectively, and then adding together the scores for the seven questions.
