What the study found
Across experimental and correlational studies, perseverative cognition was linked to differences in cardiovascular measures, cortisol and HRV. Associations depended on the parameter, design and measurement conditions.
Scope & limitations
60 eligible studies of physiological correlates of perseverative cognition in healthy participants.
Experimental induction and observational designs support different levels of inference, with variation in measurement conditions and outcomes. Pooled results should be read by physiological measure and design.
Population & sample
60 eligible studies of physiological correlates of perseverative cognition in healthy participants.
Exposure or intervention
Worry and rumination, including experimentally induced and naturally reported perseverative cognition.
Outcomes
Blood pressure, heart rate, cortisol and heart rate variability, analyzed separately.
Time frame
Measurement durations varied and were examined as a moderator; no universal recovery interval.
