This study investigated the psychometric properties of the Geriatric Anxiety Inventory (GAI) in younger adults. Participants were 212 younger adults age M = 22 (range = 17–53) years. They completed a demographic information questionnaire and self-report measures: the GAI, the Depression Anxiety Stress Scales (DASS), the Generalized Anxiety Disorder–7 (GAD-7), the Patient Health Questionnaire–9 (PHQ-9), the Penn State Worry Questionnaire (PSWQ), and the Worry Behaviors Inventory (WBI). Data from the GAI were collected at two time points, one week apart, and data from other self-report measures were collected once via Qualtrics, an online survey platform. The internal consistency and test–retest score reliability of the GAI were excellent. It had good congruent validity with other anxiety measures, limited divergent validity with depression measures, and sound convergent validity with worry measures. The GAI showed good discrimination between probable cases and noncases of generalized anxiety disorder (participants who scored ⩾8 on the GAD-7) and its optimal cutoff score for probable cases of GAD was ⩾12. A unidimensional component structure of the GAI best fit this study’s data. This study has provided preliminary evidence that the GAI is reliable and valid for use in an Australian sample of younger adults.

验证年轻人的老年焦虑量表

本研究调查了年轻人的老年焦虑量表 (GAI) 的心理测量特性。参与者是 212 名年龄M的年轻人 = 22(范围 = 17–53)年。他们完成了人口统计信息问卷和自我报告测量:GAI、抑郁焦虑压力量表 (DASS)、广泛性焦虑障碍 - 7 (GAD-7)、患者健康问卷 - 9 (PHQ-9)、Penn州忧虑问卷 (PSWQ) 和忧虑行为量表 (WBI)。GAI 的数据在两个时间点收集,相隔一周,其他自我报告测量的数据通过在线调查平台 Qualtrics 收集一次。GAI 的内部一致性和重测分数可靠性非常好。它与其他焦虑量度具有良好的一致性效度,与抑郁量度具有有限的发散效度,与担忧量度具有良好的收敛效度。GAI 对可能病例和非广泛性焦虑症病例(在 GAD-7 上得分 8 的参与者)表现出良好的区分,其对可能的 GAD 病例的最佳截止分数为 12。GAI 的一维组件结构最适合本研究的数据。这项研究提供了初步证据,表明 GAI 可靠且有效地用于澳大利亚的年轻人样本。
