Brief Summary

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.

Outcome Measures

Primary Outcomes (6)

  • Self-reported Negative Affect

    Self-reported negative affect data collected during the emotion regulation task on a 1-4 scale, with 1 meaning "not negative at all" and 4 meaning "very negative".

    Sessions 1 (baseline/initial session), 2, 3, 4, and 5, which were conducted approximately every 2-3 days over the course of 2 weeks.

  • Respiratory Sinus Arrhythmia

    Heart rate variability, or variability in time intervals between heart beats, as measured by the log of the root mean square of the successive RR interval differences (ln(RMSSD)). RR intervals are interbeat intervals between consecutive heartbeats. Average ranges for ln(RMSSD) for 30 to over 75 years of age range from 3.2 to 3.9 for women and 3.2 to 3.8 for men.

    Sessions 1 (baseline/initial session), 2, 3, 4, and 5, which were conducted approximately every 2-3 days over the course of 2 weeks.

  • Neural Activity

    Picture Induced Negative Emotion Signature (PINES) is an independently-defined, validated whole-brain neural pattern map for negative appraisal, with positive weights for areas like the amygdala and insula. PINES Correspondence Scores (PCS) are correlation coefficients derived for each trial type (Look Neutral, Look Negative, Reappraise Negative) per participant by correlating each participant's whole-brain pattern during the task to PINES. PCS correlation coefficients range from -1 to 1, and higher values reflect greater correlation to PINES and thus greater negative affect.

    Sessions 1 (baseline/initial session) and 5, which were conducted approximately 2 weeks apart.

  • Grief Rumination

    Grief rumination assessed via Utrecht Grief Rumination Scale (UGRS) and the Inventory for Complicated Grief (ICG). UGRS items are rated from 1 (never) to 5 (very often). Scores range from 15 to 75; higher numbers represent higher grief rumination. These are summed from 3-item subscales Reactions, Injustice, Counterfactuals, Meaning, and Relationships, which all have score ranges of 3-15. Higher scores represent greater grief rumination. The ICG assesses grief via 19 first-person statements on a scale of 0 (Never) to 4 (Always) with a range from 0-76. Higher numbers reflect greater grief.

    Sessions 1 (baseline/initial session) and 5, which were conducted approximately 2 weeks apart, and at the 1- and 2-month follow-ups.

  • Depressive Symptoms

    Symptoms of depression assessed via the Center for Epidemiological Studies Depression (CES-D) scale, which asks participants to rate how often in the past week they have experience symptoms of depression, ranging from 0 (Rarely or none of the time) to 3 (Most of the time). Scores range from 0 to 60, with higher scores indicating higher levels of depressive symptoms.

    Sessions 1 (baseline/initial session) and 5, which were conducted approximately 2 weeks apart, and at the 1- and 2-month follow-ups.

  • Perceived Stress

    Perceived stress assessed via the Perceived Stress Scale (PSS), consisting of 10 self-reported items asking participants how often they felt or thought a certain way, ranging from 0 (Never) to 4 (Very Often). Total range is 0 to 40, with higher scores indicate higher levels of perceived stress.

    Sessions 1 (baseline/initial session), 2, 3, 4, and 5, which were conducted approximately every 2-3 days over the course of 2 weeks, and at the 1- and 2- month follow-up.

Secondary Outcomes (3)

  • Frequency of Reappraisal Usage

    Sessions 1 (baseline/initial session) and 5, which were conducted approximately 2 weeks apart, and at the 1- and 2-month follow-ups.

  • Physical Health

    Sessions 1 (baseline/initial session) and 5, which were conducted approximately 2 weeks apart, and at the 1- and 2-month follow-ups.

  • Inflammatory Biomarkers

    Sessions 0 and 6, which were conducted approximately 2-3 weeks apart.

Study Arms (2)

Distancing

EXPERIMENTAL

Participants will receive structured cognitive emotion regulation training from an experimenter during an approximately 10-minute interaction in which detailed instructions for implementation of the distancing strategy is explained (i.e. appraising an emotional stimulus as an objective, impartial observer).

Behavioral: Cognitive Emotion Regulation Training

Reinterpretation

ACTIVE COMPARATOR

Participants will receive structured cognitive emotion regulation training from an experimenter during an approximately 10-minute interaction in which detailed instructions for implementation of the reinterpretation strategy is explained (i.e. imagining a better outcome than what initially seemed apparent).

Behavioral: Cognitive Emotion Regulation Training

Interventions

Cognitive emotion regulation training via cognitive reappraisal involves the ability to modify the trajectory of an emotional response by thinking about and appraising emotional information in an alternative, more adaptive way. Reappraisal to down-regulate negative emotion can be operationalized via two tactics: psychological distancing and reinterpretation. The current study will randomly assign participants to receive a brief course of reappraisal training using either psychological distancing or reinterpretation.
