简要总结
The purpose of this study is to investigate if a brief online-delivered cognitive-behavioral intervention can reduce the degree of dysfunctional worry related to the Covid-19 pandemic, compared to a wait-list control condition.
详细描述
Worries about the immediate and long-term consequences of the ongoing Covid-19 pandemic are largely justified in the current climate of uncertainty. However, dysfunctional worry, that is, pervasive worry that is disproportionate in its intensity or duration, and that significantly interferes with every-day problem-solving or goal-driven behavior, is clearly counterproductive. Research has also indicated that repeated media exposure to a community crisis can lead to increased anxiety and heightened stress responses, that can give a downstream effect on health, and misplaced health-protective and help-seeking behaviors which, in turn, may overburden health care facilities. There is an urgent need to develop a brief, scalable intervention to target such dysfunctional worry in the general population.
The current randomized controlled trial will evaluate the feasibility and efficacy of a brief online-delivered cognitive behavioral intervention designed to target dysfunctional worry related to the Covid-19 pandemic. 670 individuals are randomized to intervention or to waiting-list. The hypothesis is that the brief self-guided intervention will show significant within-group reductions in self-rated worry from baseline (week 0) to post-treatment (week 3), and that these improvements will be larger than those seen in the wait-list control group. The wait-list group will be crossed over to receive the intervention after three weeks (post-treatment). All participants will be followed-up one month and one year after the end of the intervention.

研究组 & 干预措施
Intervention: Online Cognitive-Behavioral intervention
The three-week intervention is a structured self-guided program without therapist support, administered via a secure web platform and organized in five brief modules. The treatment is provided through an encrypted online platform (login through BankID and double authentication) provided by the eHealth Core facility at Karolinska Institutet
干预措施: Internet-delivered cognitive behavior therapy (ICBT) for dysfunctional worry related to the Covid-19 pandemic (Behavioral)
Wait-list
The wait-list controlled composes of no intervention for three weeks. Participants randomized to the wait-list group will be crossed over to receive the Online Cognitive-Behavioral intervention after three weeks (post-treatment).
结局指标
主要结局
• Covid-19-adapted version of the self-rated Generalized Anxiety Disorder Scale-7 (GAD-7)
时间窗: Basline (week 0), during treatment (week 1 and week 2), post treatment (week 3), at one-month after treatment and also one year follow up.
A 7-item self-rated scale to assess symtom severity of worry. Total score ranging from 0 to 21. Effects will be expressed as the change from baseline to last post-treatment value (Week 0-Week 3) period. Effects will also be assessed at one month and one year post-treatment.

- Adverse events (AE)(Post treatment (week 3))
- Intolerance of uncertainty Scale (IUS)(Baseline (week 0), post treatment (week 3), at one-month after treatment and also one year follow up.)
- Adapted Covid-19 version of the Work and Social Adjustment Scale (WSAS)(Basline (week 0), during treatment (week 1 and week 2), post treatment (week 3), at one-month after treatment and also one year follow up.)
