Abstrakt: Background: Impaired emotion regulation (ER) contributes to major depression, and suicidal ideation (SI) and behavior. ER is typically studied by explicitly directing participants to regulate, but this may not capture depressed individuals' spontaneous tendencies to engage ER in daily life.
Methods: In N=82 participants with major depressive disorder (MDD), we examined the relationship of spontaneous engagement of ER to real-world responses to stress. We used a machine learning-derived neural signature reflecting neural systems underlying cognitive reappraisal (an ER strategy) to identify reappraisal-related activity while participants recalled negative autobiographical memories under the following conditions: 1) unstructured recall; 2) distanced recall, a form of reappraisal; and 3) immersed recall (comparison condition). Participants also completed a week of ecological momentary assessment (EMA) measuring daily stressors, suicidal ideation (SI), and negative affect.
Results: Higher reappraisal signature output for the unstructured period, a proxy for the spontaneous tendency to engage ER, was associated with greater increases in SI following stressors (b=0.083, p=0.041). Higher signature output for distanced recall, a proxy for the capacity to engage ER when directed, was associated with lower negative affect following stressors (b=-0.085, p=0.029). Output for the immerse period was not associated with EMA outcomes.
Conclusions: Findings suggest that, in MDD, the spontaneous tendency to react to negative memories with attempts to reappraise may indicate greater reactivity to negative cues; while intact capacity to use reappraisal when directed may be associated with more adaptive responses to stress. These data have implications for understanding stress-related increases in suicide risk in depression.
