OBJECTIVES: To investigate the validity and reliability of the Geriatric Anxiety
Inventory in screening for anxiety in older inpatients post-stroke. DESIGN: Longitudinal. SUBJECTS: A total of 81 inpatients with stroke aged 65 years or
older were recruited at four centres in England. MAIN MEASURES: At phase 1 the
Geriatric Anxiety Inventory and the Hospital Anxiety and Depression Scale were
administered and then the Structured Clinical Interview for Diagnostic and
Statistical Manual of Mental Disorders 4th edition (phase 2). The Geriatric
Anxiety Inventory was repeated a median of seven days later (phase 3). RESULTS:
Internal reliability of the Geriatric Anxiety Inventory was high (alpha = 0.95)
and test-retest reliability acceptable (tauB = 0.53). Construct validity was
evident relative to the Hospital Anxiety and Depression Scale - Anxiety subscale
(tauB = 0.61). At a cut off of 6/7, sensitivity of the Geriatric Anxiety
Inventory was 0.88, specificity 0.84, with respect to the Structured Clinical
Interview anxiety diagnosis. Hospital Anxiety and Depressions Scale - Anxiety
subscale sensitivity was 0.88, specificity 0.54 at the optimum cut off of 5/6. A
comparison of the areas under the curve of the Receiver Operating Characteristics
for the two instruments indicated that the area under the curve of the Geriatric
Anxiety Inventory was significantly larger than that of the Hospital Anxiety and
Depressions Scale - Anxiety subscale, supporting its superiority. CONCLUSIONS:
The Geriatric Anxiety Inventory is an internally consistent, reliable (stable)
and valid instrument with acceptable sensitivity and specificity to screen for
anxiety in older inpatients with stroke.
