目的：评估老年焦虑量表（GAI）在澳大利亚社区老年妇女队列中的心理测量学特性和健康相关性。方法：对60岁及以上女性（N = 286）进行基于人群的横断面研究。结果如下：GAI表现出良好的内部一致性，并表现出良好的并发效度对状态一半的Spielberger状态特质焦虑量表和NEO五因素量表的神经质域。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。患有广泛性焦虑症（GAD）的女性比没有这种病史的女性有更高的GAI评分。在该队列中，检测当前GAD的最佳临界点为8/9。虽然GAI的设计包含很少的身体项目，但有更多一般医疗问题或认为自己的一般健康状况较差的女性的GAI得分较高。结论：GAI是一种专门用于测量老年人焦虑的新量表。在这个澳大利亚老年妇女队列中，该仪器具有良好的心理测量特性。
Objective: To assess the psychometric properties and health correlates of the Geriatric Anxiety Inventory (GAI) in a cohort of Australian community-residing older women. Method: Cross-sectional study of a population-based cohort of women aged 60 years and over (N = 286). Results: 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. Conclusion: 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.
