Psychometric properties of the Spanish version of the Geriatric Anxiety Inventory

Abstract

Background: The Geriatric Anxiety Inventory (GAI) was developed for assessing anxiety in older adults. The objectives of this work were: (a) to analyze the psychometric properties of the Spanish version of the GAI, and (b) to explore the associations between anxiety and other variables related to emotional distress (depression) and emotion regulation (rumination, experiential avoidance, and emotion suppression). Methods: Three-hundred-and-two people (75.5% female) aged 60 years and over living in the community participated in this study. Anxiety, depression, rumination, suppression and experiential avoidance were measured. Results: Three factors explaining 50.11% of the variance were obtained. The obtained internal consistency for the total scale was 0.91, with alphas ranging between 0.71 and 0.89 for the factors. Significant associations between all the GAI factors, the GAI total score, and depression, rumination, and experiential avoidance were found (all p < 0.01). Women reported higher scores than men for both the GAI total score and for all of the subscales. However, no significant gender differences were found between people with scores higher than the cut-off score for the GAI. Conclusions: The results of this study suggest that the Spanish version of the GAI displays good psychometric properties. Further, our data suggest that the scale can be recommended for measuring anxiety in non-clinical older Spanish persons, and may be a useful instrument to be used in research studies aimed at analyzing anxiety and its correlates among older adults. © International Psychogeriatric Association 2011.
