Scores of 5, 10, and 15 are taken as the cut-off points for mild, moderate and severe anxiety, respectively

  • when used as a screening tool, further evaluation is recommended when the score is 10 or greater
  • study evidence revealed a cut point of 10 was identified that optimized sensitivity (89%) and specificity (82%) for diagnosis of generalised anxiety disorder

Limitations:

  • the GAD-7 scale focuses on only 1 anxiety disorder, although there are many patients with other anxiety disorders, such as social phobia and posttraumatic stress disorder, who need clinical attention
  • the GAD-7 provides only probable diagnoses that should be confirmed by further evaluation
