Generalized anxiety disorder scale-7 [GAD-7].
anxiety disorder, anxiety
The 7-item GAD-7 is another valid and efficient scale of the PHQ, which screens for generalized anxiety disorder and assesses its severity on a 4-point Likert scale from 0 (“not at all”) to 3 (“nearly every day”). When assessing generalized anxiety using GAD-7, scores of ≥5, ≥10, and ≥15 are considered mild, moderate, and severe generalized anxiety, respectively.
