广泛性焦虑症严重程度量表（GADSS）是广泛性焦虑症（GAD）症状严重程度的有效测量。考虑到老年人GAD的高患病率以及需要一个有效的量表来评估该年龄组GAD的严重程度，作者研究了老年人GADSS的心理测量学特性。设计、设置、参与者：作者检查了134名符合当前GAD诊断标准的老年受试者（60岁及以上），33名健康老年对照受试者（60岁及以上）和186名诊断为GAD的年轻受试者（18 - 60岁）。结果：老年人的GADSS具有较高的内部一致性（原始Cronbach’s α = 0.76）。Pearson相关分析显示，GADSS、汉密尔顿焦虑量表与宾州大学焦虑问卷之间存在显著正相关。Pearson相关分析显示GADSS和SF-36之间呈显著负相关。GADSS与简易精神状态检查量表、老年病累积疾病评定量表无相关性。结论：GADSS在老年广泛性焦虑患者中具有良好的收敛效度、同时效度和区分效度。作者得出结论，GADSS是老年人GAD症状严重程度的有效衡量标准。
The Generalized Anxiety Disorder Severity Scale (GADSS) is a validated measure of Generalized Anxiety Disorder (GAD) symptom severity. Given the high prevalence of GAD in the elderly and the need for a validated scale to assess GAD severity in this age group, the authors examined the psychometric properties of the GADSS in the elderly. Design, Setting, Participants: The authors examined a sample of 134 elderly subjects (age 60 and above) who met diagnostic criteria for current GAD, 33 healthy elderly comparison subjects (age 60 and above) and 186 younger subjects (age 18 - 60) diagnosed with GAD. Results: The GADSS had a high internal consistency in the elderly subjects (raw Cronbach's alpha = 0.76). Pearson correlations showed a significant positive correlation between GADSS, Hamilton Rating Scale for Anxiety and Penn State Worry Questionnaire. Pearson correlations showed an inverse significant correlation between GADSS and the Medical Outcome Study SF-36. There was no correlation between GADSS and Mini Mental State Examination or Cumulative Illness Rating Scale for Geriatrics. Conclusions: The results showed a good convergent, concurrent, and discriminant validity of the GADSS when used for elderly with GAD. The authors conclude that GADSS is a valid measure of GAD symptom severity in older adults.
