A study of the validity and the reliability of the Geriatric Anxiety Inventory in screening for anxiety after stroke in older inpatients

Abstract

Objectives: To investigate the validity and reliability of the Geriatric Anxiety Inventory in screening for anxiety in older inpatients post-stroke. Design: LongitudinalSubjects: A total of 81 inpatients with stroke aged 65 years or older were recruited at four centres in England.

Frequency of anxiety after stroke: An updated systematic review and meta-analysis of observational studies

“…GAD was reported in eight studies. 43,45,47,59,73,81,86,103 However, a pooled prevalence was not calculated because in some studies it is not clear if GAD had been reported as a subtype of anxiety or as a generic anxiety diagnosis. Similarly, rates were not pooled for phobic disorder, which was reported in three studies, 59,73,101 because it is unclear whether the category “phobic disorder” includes all types of phobias or is a distinct phobia subtype.…”

A Bifactor and item response analysis of the geriatric anxiety inventory

“…Generally, the scale has demonstrated excellent reliability and internal consistency, discriminant ability, predictive, and convergent validity (e.g. in stroke patients, Kneebone et al, 2016). As such, the GAI scale seems to have proven itself as a viable instrument with strong psychometric properties.…”

Prevalence of anxiety in people with aphasia after stroke

“…It may well be it is not an appropriate instrument to use in this population, or that a lower cut-off is more appropriate if it is to be used. A lower cut-off for those with stroke has been found to be required for other instruments assessing anxiety in stroke (e.g., Kneebone, Fife-Schaw, Lincoln, & Harder, 2015). Further, it should be noted that a score of >5 on the GAD-7 is considered indicative of "mild symptoms" of anxiety on this measure.…”
