Metabeliefs about worry, cognitive fusion, and acceptance: associations and mediations analysis

Beliefs about the uncontrollability of worry appear to play a pivotal role in sustaining worry, primarily through their influence on cognitive fusion.

However, as this is an exploratory and cross-sectional study, conclusions about treatment mechanisms should be drawn cautiously, and future longitudinal and experimental studies are needed to strengthen these insights.
