Anxiety disorders are among the most common mental health concerns in older adults.

Untreated anxiety can lead to cognitive impairment, disability, poor physical health, and a poor quality of life. But dementia can also be present in individuals in this age group, which means mood disorders such as anxiety and depression can be overlooked, as symptoms such as memory impairment and changes in everyday activities are similar.

Developed by researchers at The University of Queensland in Brisbane, Australia, the Geriatric Anxiety Inventory (GAI) is a simple tool that enables screening in older adults who may have undetected anxiety. The GAI can help point the way to a proper diagnostic workup and timely intervention. Topics covered include feelings of fearfulness, worry, physical symptoms of anxiety, and concerns about the impacts of worry and anxiety.

What is the GAI?

The GAI is a simple 20-item questionnaire for quickly screening adults aged 50 and over for anxiety disorders.

The straightforward self-report ‘agree-disagree’ scale lets practitioners know if they need to pursue a diagnosis of an anxiety disorder. Available in 24 languages, the GAI has been used and trusted by health practitioners in over 20 countries worldwide since 2005.

Dr Diane CorserClinical & Gero-Psychologist, DirectorLifespan Health

"The GAI is easy to administer which makes it perfect for assessing older adults living in residential aged care with physical and cognitive limitations. It is very reassuring to know that we have a well-validated tool that is so well suited to use for our clients in this setting."

Manon WathierMental Health Occupational TherapistQueensland Health

"I find both questionnaires very user friendly. They are easy to understand. The scores are also easy to explain to clients.
They make a great pro and post intervention outcome measure. I think it a therapeutic intervention when I come back months later and show the scores have improved. People are often pleasantly surprised!"
