简要总结
The aim of this study is to evaluate if internet- delivered cognitive behavior therapy (CBT), based on exposure principles and behavioral activation, improves QoL and symptom burden in patients with symptomatic atrial fibrillation (AF), controlling for expectancy of improvement and attention from a caregiver, using an active control group (stress management). The study will include 260 patients with symptomatic AF despite optimal medical treatment in accordance with current guidelines.
详细描述
Atrial fibrillation (AF) is the most common cardiac arrhythmia (irregular heartbeat) affecting 3% of the population. AF is associated with poor quality of life (QoL) and large costs for society. In a considerable proportion of patients, AF symptoms (e.g., palpitations, fatigue, and chest pain) are not alleviated by current medical or interventional treatments. Psychological factors can worsen AF symptoms, and anxiety and depression are common among AF patients. Symptom preoccupation and avoidance of social and physical activities are likely to play important roles in the development of anxiety, depression, disability and healthcare utilization.
The aim is to evaluate if CBT, based on behavioral activation and exposure principles, improves wellbeing and QoL in symptomatic AF patients controlling for expectancy of improvement and attention from a caregiver using an active control group receiving stress management treatment (SMT).
Method: A randomized controlled trial. Participants are randomized to internet- delivered exposure-based CBT (N=130) or to SMT (N=130). Participants in both groups receive weekly therapist support through online written communication. The internet-delivered SMT-treatment includes life-style advice (e.g., exercise, sleep advice), relaxation and problem-solving skills to reduce stress. Both treatments lasts 10 weeks and are comparable regarding number of treatment modules, treatment burden and attention from the treating psychologist.

时间窗: From baseline to 9 months
The AFEQT is an atrial fibrillation-specific measure that taps into the QoL-domains: symptoms, daily activities, treatment concern, and treatment satisfaction. Total score ranges from 0 (severe symptoms and disability) to 100 (no symptoms and disability).
