A Measure for Assessing Generalized Anxiety Disorder 7
GAD-7
General
The GAD-7 is a module from the Patient Health Questionnaire (PHQ-D). It is a revision of the 'other anxiety disorders' module from the first version of the Patient Health Questionnaire (PHQ). Although the GAD-7 was developed primarily to assess Generalized Anxiety Disorder, it is also suitable for screening for various anxiety disorders, such as social phobia or panic disorder. The GAD-7 is recommended by the DSM-5 Working Group of the American Psychiatric Association as an instrument to measure the severity of Generalized Anxiety Disorder according to DSM-5 criteria. The items of the GAD-7 describe the main diagnostic criteria for Generalized Anxiety Disorder. The GAD-7 asks how often the seven core symptoms of Generalized Anxiety Disorder were suffered from within the past two weeks. The four-point response scale ranges from 0 (not at all) to 3 (almost every day).
