Geriatric Anxiety Inventory

A score of 9 is at the threshold for clinically significant anxiety and warrants further clinical evaluation. A score of 8 (just below threshold) does not exclude anxiety disorder but indicates that the GAI screening suggests minimal anxiety; however, clinical judgment must be applied—if the patient reports significant worry, fear, or functional impairment despite a score of 8, clinical assessment should proceed regardless of the screening cutoff.

Medical illness and anxiety frequently co-occur in older adults. A high GAI score in the presence of medical comorbidity may reflect anxiety, medical disease, medication effects, or a combination. The GAI's focus on cognitive/affective symptoms rather than somatic symptoms helps distinguish anxiety from medical disease, but medical evaluation should still be conducted to rule out medical contributors (thyroid dysfunction, cardiac disease, medication side effects) before attributing symptoms solely to anxiety.

No; the GAI screens for clinically significant anxiety symptoms but does not differentiate specific anxiety disorder diagnoses. A high GAI score indicates anxiety is present and warrants further evaluation, but clinical diagnostic interview is necessary to determine the specific disorder type and whether criteria are met for a particular DSM-5 diagnosis.

The GAI-5 is a brief screening tool derived from the five most discriminative items of the full 20-item GAI. It is highly efficient (~2 minutes) and useful for rapid screening in busy settings, but with somewhat reduced sensitivity compared to the full scale. The 20-item GAI is recommended for comprehensive assessment; the GAI-5 is appropriate for brief screening when time is limited.
