Why the study?
This research aimed to analyze the psychometric properties of the Persian version of the Geriatric Anxiety Inventory (GAI-PV) and its short form (GAI-PV-SF) among older adults in Iran.
Does the Persian version of the Geriatric Anxiety Inventory accurately screen for generalized anxiety disorder in older Iranian adults?
Cross-Sectional (n=198)
Does the Persian version of the Geriatric Anxiety Inventory accurately screen for generalized anxiety disorder in older Iranian adults?
Effect estimate: AUC 0.89 (95% CI 0.82-0.97)
The Persian version of the Geriatric Anxiety Inventory and its short form demonstrate sound psychometric properties and can be used as accurate screening tools for generalized anxiety disorder in elderly Iranian populations.
GAI-PV supports GAD screening in Iranian elders; leaves open prospective validation before routine use.
Background The aim of this research was to analyze the psychometric properties of the Persian version of the Geriatric Anxiety Inventory (GAI-PV) and its short form (GAI-PV-SF) in a sample of older adults in Iran.Methods In this cross-sectional study, a sample of 150 community-dwelling and a psychogeriatric sample of 48 adults older than 60 years completed the GAI-PV and GAI-PV-SF, the anxiety sub-scale of the General Health Questionnaire (GHQ-28), the Geriatric Depression Scale (GDS-15), and the Structured Clinical Interview for DSM-IV (SCID-I).Results Both the GAI-PV and GAI-PV-SF exhibited excellent internal consistency and desirable concurrent validity against GHQ-28 and GDS-15. The optimal cutpoint score to detect current generalized anxiety disorder (GAD) was 10/11 and 13/14 for GAI-PV in the community-dwelling and psychogeriatric samples, respectively, and 3/4 for GAI-PV-SF in both study samples. A good test-retest reliability and a single-factor structure were also demonstrated.Conclusion Sound psychometric properties of the GAI-PV in both subsamples suggest that the instrument could be used successfully as an accurate screening instrument in the elderly Iranian population.

Shati et al. (2019) conducted a cross-sectional in Generalized Anxiety Disorder (n=198). Geriatric Anxiety Inventory Persian version (GAI-PV) vs. Structured Clinical Interview for DSM-IV (SCID-I) was evaluated on Diagnostic accuracy (Area Under the Curve) of GAI-PV for generalized anxiety disorder in community-dwelling older adults (AUC 0.89, 95% CI 0.82-0.97).
