Full RNT-focused intervention
RNT-focused
The full RNT-focused intervention was developed based on principles of RFCBT [The app consists of the following modules: psychoeducation on RNT and different strategies to reduce RNT, identifying personal triggers of RNT and stress, concreteness training, engaging in opposite actions, relaxation/mindfulness-based exercises, self-compassion, setting priorities to cope with stress-related worries, tracking current emotions and repetitive thoughts, and making specific if–then-plans to apply the acquired strategies in every-day life.The app is organized into different sections. The section Participants will be able to choose activities from these different sections and adjust the intervention to their current needs. They will be instructed to use the app as consistently as possible over a period of 6 weeks. Additionally, the app will automatically display pop-up reminders (three to four per week) to complete certain exercises (i.e., particular challenges and tools) in the app. The number of pop-up reminders (three per each tool and three per each challenge) is balanced across the different exercises so that participants will receive the same number of reminders for each of the tools and challenges.To make the app as user-friendly and helpful as possible, it combines animations, videos, audio exercises, explanatory texts, and multiple choice and open-question formats. Additionally, the app asks participants to indicate how helpful the exercise was after completion of each challenge or tool and gives conditional feedback and tips based on participants’ answers.The app was designed in cooperation with the software developer m-Path and is compatible with iOS and Android.
