Persian version of the Geriatric Anxiety Scale: translation and preliminary psychometric properties among Iranian older adults.

Author information

  • 1Ferdowsi University of Mashhad, Mashhad, Iran.



The Geriatric Anxiety Scale (GAS) is a new self-report screening measure designed for older adults. Due to the burgeoning Iranian population of older adults and the need for validated, culturally-appropriate screening measures for anxiety in Iran, the purposes of the present study were to translate the GAS into Persian and to explore its preliminary psychometric properties.


Iranian older adults (N = 295; M age = 67.0 years) completed the GAS and the Iranian version of the Geriatric Depression Scale (GDS-15).


Cronbach's alpha for the GAS total score and the GAS subscales were excellent (Total score α = .92; Cognitive α = .81; Somatic α = .84; Affective α = .80). As expected, each subscale was significantly positively correlated (all p's < .01) with the other subscales. The subscales share common variance ranging from 42% to 56%. The GAS total score and GAS subscale scores were significantly positively correlated with the GDS-15, with medium effect sizes (GAS Total r = .55; Cognitive r = .51; Somatic r = .50; Affective r = .48). Finally, exploratory and confirmatory factor analyses were conducted to investigate the factor structure of the Persian version of the GAS. Results support a one factor solution (general anxiety) for this Iranian sample.


This study provides preliminary psychometric support for the Persian version of the GAS as a screening measure for anxiety in Iranian older adults, with a one-dimensional factor structure.
