Internet based self-help for panic disorder (PD) has proven to be effective. However, studies so far have focussed on treating a full-blown disorder. Panic symptoms that do not meet DSM-IV criteria are more prevalent than the full-blown disorder and patients with sub-clinical panic symptoms are at risk of developing PD. This study is a randomised controlled trial aimed to evaluate an Internet based self-help intervention for sub-clinical and mild PD compared to a waiting list control group.
Participants with mild or sub-clinical PD (N = 128) will be recruited in the general population. Severity of panic and anxiety symptoms are the primary outcome measures. Secondary outcomes include depressive symptoms, quality of life, loss of production and health care consumption. Assessments will take place on the Internet at baseline and three months after baseline.
Results will indicate the effectiveness of Internet based self-help for sub-clinical and mild PD. Strengths of this design are the external validity and the fact that it is almost completely conducted online.
基于互联网的惊恐障碍(PD)自助疗法已被证明是有效的。然而,迄今为止的研究都集中在治疗完全发作的疾病上。不符合 DSM-IV 标准的惊恐症状比完全发作的疾病更为普遍,且有亚临床惊恐症状的患者有发展为 PD 的风险。本研究是一项随机对照试验,旨在评估针对亚临床和轻度 PD 的基于互联网的自助干预措施与等待名单对照组相比的效果。
将在普通人群中招募轻度或亚临床 PD 患者(N=128)。惊恐和焦虑症状的严重程度是主要的结局测量指标。次要结局指标包括抑郁症状、生活质量、生产损失和医疗保健消费。评估将在基线时和基线后三个月在互联网上进行。
结果将表明基于互联网的自助疗法对亚临床和轻度 PD 的有效性。该设计的优势在于其外部有效性以及几乎完全在网上进行的事实。
