BACKGROUND & OBJECTIVES: Groups of clients and community volunteers with Generalized Anxiety Disorder (GAD) and clients with Panic Disorder were compared to a group with elevated worry but without GAD on a range of measures, to identify individual differences beyond a high propensity to worry.
Participants completed standardised questionnaires and a behavioural worry task that assesses frequency and severity of negative thought intrusions.
Relative to high worriers, clients with GAD had higher scores on trait anxiety, depression, more negative beliefs about worry, a greater range of worry topics, and more frequent and severe negative thought intrusions. Relative to community volunteers with GAD, clients in treatment reported poorer attentional control. Compared to clients with Panic Disorder, clients with GAD had higher trait anxiety, propensity to worry, negative beliefs and a wider range of worry content.
Results confirmed expectations of group differences based on GAD diagnostic criteria, but also revealed other differences in mood, characteristics of worry, and perceived attentional control that may play a role in the decision to seek treatment.
广泛性焦虑障碍（GAD）患者群体、社区志愿者群体以及有焦虑但未达 GAD 诊断标准的群体，在一系列指标上与高担忧倾向群体进行了比较，以确定除了高担忧倾向之外的个体差异。
参与者完成了标准化问卷和行为担忧任务，评估负性思维闯入的频率和严重程度。
与高担忧者相比，GAD 患者的特质焦虑、抑郁得分更高，对担忧的负面信念更多，担忧的主题范围更广，负性思维闯入的频率和严重程度更高。与有 GAD 的社区志愿者相比，接受治疗的患者报告的注意力控制能力更差。与惊恐障碍患者相比，GAD 患者的特质焦虑、担忧倾向、负性信念以及担忧内容的范围更广泛。
结果证实了基于 GAD 诊断标准的群体差异预期，但也揭示了情绪、担忧特征和感知注意力控制方面的其他差异，这些差异可能在寻求治疗的决策中发挥作用。
