Study 1a: The effect of a brief detached mindfulness intervention on high socially anxious’ metacognitive and physiological disturbances during a socially stressful task.
This study will build upon “Reducing anxiety during social stress: The impact of short digital interventions targeting metacognitive and heart rate variability” 2022-11-14-M.E. Kret-V1-4339. We improved the limitations of the aforementioned study to examine whether the improvements to the detached mindfulness intervention would show effectiveness not only for the physiological domain but also the metacognitive domain. Furthermore, In our current study, we aim to take the investigation of brief mindfulness interventions a step further by evaluating the interventions’ effectiveness in adolescents with subclinical levels of social anxiety. This pre-registration outlines study 1a, which is part of an overarching study 1 that also has a part b where the task is identical, but the intervention mechanism differs. In this study, we will focus on metacognition and test the effects of a detached mindfulness intervention compared to a matched control condition on reducing cognitive and physiological symptoms before, during, and after a real-life socially stressful task, i.e., public speaking. Along with the effect of the intervention, we want to explore potential mechanisms of change and test whether negative metacognitive beliefs mediate the effects of detached mindfulness on the symptoms
