Geriatric Anxiety Scale

The Geriatric Anxiety Scale (GAS; Segal, June, Payne, Coolidge, & Yochim, 2010) is a 30-item self-report measure used to assess anxiety symptoms among older adults. Individuals are asked to indicate how often they have experienced each symptom during the last week, answering on a 4-point Likert scale ranging from “Not at all” (0) to “All the time” (3). GAS items were derived from the broad range of anxiety disorder symptoms in the DSM-IV-TR. Scoring provides a total score and 3 subscales (somatic symptoms, cognitive symptoms, and affective symptoms) for which normative and interpretive guidelines are available.

The GAS total score is based on the first 25 items and ranges from 0 to 75. The additional 5 content items assess areas of anxiety commonly reported to be of concern for older adults, including the following: concern about finances, concern about one’s health, concern about children, fear of dying, and fear of becoming a burden to others. These content items are used clinically and they do not load on the total score. The GAS demonstrated high internal consistency of scale scores and strong evidence of validity for the quantitative assessment of anxiety symptoms in diverse community and clinical samples of older adults (Gould, Segal, Yochim, Pachana, Byrne, & Beaudreau, 2014; Segal et al., 2010; Yochim, Mueller, June, & Segal, 2011; Yochim, Mueller, & Segal, 2013). Notably, a 10-item short version, called the GAS-10, is available and has strong psychometric properties as a screening instrument in diverse samples of older adults (Mueller, Segal, Gavett, Marty, Yochim, June, & Coolidge, 2015).

The GAS has been translated successfully into several languages including German, Chinese, Persian, and Turkish, and several other linguistic adaptations are currently underway.

The GAS is free for use by individual clinicians or researchers. For those individuals who wish to use the GAS for research or clinical purposes, please complete the following form. Upon review, Dr. Segal will communicate with you directly and provide the measure.
