Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study investigates the underlying mechanisms of a novel emotion regulation intervention among recently bereaved spouses. More specifically, this study examines how thinking about an emotional stimulus in a more adaptive way can affect the relationship between psychological stress, psychophysiological biomarkers of adaptive cardiac response, and brain activity. The emotion regulation strategy targeted is reappraisal, specifically reappraisal-by-distancing (i.e., thinking about a negative situation in a more objective, impartial way) versus reappraisal-by-reinterpretation (i.e., thinking about a better outcome for a negative situation than what initially seemed apparent). The study seeks to determine if relatively brief, focused reappraisal training in bereaved spouses will result in reduction of self-reported negative affect, increases in respiratory sinus arrhythmia (RSA; a measure of heart rate variability reflecting adaptive cardiac vagal tone), reduction in blood-based inflammatory biomarkers, and changes in neural activity over time. Reappraisal-by-distancing is expected to lead to greater changes in these variables relative to reappraisal-by-reinterpretation. Additionally, it is expected that across time decreases in self-reported negative affect, increases in RSA, reductions in blood-based inflammatory biomarker levels, and changes in neural activity will in turn lead to reductions in depressive symptoms and grief rumination. Finally, it is expected that distancing training will lead to reductions in depressive symptoms and grief rumination that are mediated by changes in the targeted neurobiological and behavioral mechanisms.
