Screening for Anxiety Symptoms With the Generalized Anxiety Disorder-2 Versus Generalized Anxiety Disorder-7 in Children With Headache or Epilepsy

This study evaluated the accuracy of the two-item GAD-2 scale compared to the seven-item GAD-7 for screening anxiety in children with headache and epilepsy attending neurology appointments. While the GAD-2 showed strong correlation with GAD-7 and high overall accuracy (89% sensitivity, 91% specificity), it would miss 11% of children with moderate-to-severe anxiety symptoms if used as a standalone screening tool.
