To assess the psychometric properties and health correlates of the Geriatric Anxiety Inventory (GAI) in a cohort of Australian community-residing older women.
Cross-sectional study of a population-based cohort of women aged 60 years and over (N = 286).
The GAI exhibited sound internal consistency and demonstrated good concurrent validity against the state half of the Spielberger State Trait Anxiety Inventory and the neuroticism domain of the NEO five-factor inventory. GAI score was significantly associated with self-reported sleep difficulties and perceived memory impairment, but not with age or cognitive function. Women with current DSM-IV Generalized Anxiety Disorder (GAD) had significantly higher GAI scores than women without such a history. In this cohort, the optimal cut-point to detect current GAD was 8/9. Although the GAI was designed to have few somatic items, women with a greater number of general medical problems or who rated their general health as worse had higher GAI scores.
The GAI is a new scale designed specifically to measure anxiety in older people. In this Australian cohort of older women, the instrument had sound psychometric properties.
评估老年焦虑量表（GAI）在澳大利亚社区居住的老年女性队列中的心理测量特性和健康相关性。
对年龄在 60 岁及以上的人群进行基于人群的横断面研究（N=286）。
GAI 表现出良好的内部一致性，并与 Spielberger 状态特质焦虑量表的状态半部分和 NEO 五因素量表的神经质领域具有良好的同时效度。GAI 评分与自我报告的睡眠困难和感知记忆障碍显著相关，但与年龄或认知功能无关。当前患有 DSM-IV 广泛性焦虑症（GAD）的女性的 GAI 评分明显高于没有此类病史的女性。在该队列中，检测当前 GAD 的最佳截断值为 8/9。尽管 GAI 旨在具有较少的躯体项目，但患有更多一般医疗问题或自评总体健康状况较差的女性的 GAI 评分较高。
GAI 是专门为测量老年人焦虑而设计的新量表。在澳大利亚的老年女性队列中，该工具具有良好的心理测量特性。
