Associations between emotion reactivity to daily interpersonal stress and acute social-evaluative stress during late adolescence.

Emotion reactivity refers to the intensity of changes in positive and negative emotion following a stimulus, typically studied with respect to daily stressors (e.g., arguments, demands) or laboratory stressors, including the Trier Social Stress Test (TSST). Yet, it is unclear whether emotion reactivity to daily and to laboratory stressors are related. The present study examined whether greater emotion reactivity to daily stressors (i.e., arguments, demands) is associated with greater reactivity to the TSST. Late adolescents (N = 82; M = 18.35, SD = 0.51, range 17-19; 56.1% female; 65.9% Latine, 34.2% European American) reported whether they experienced arguments and demands with friends, family, and individuals at school and their negative and positive emotion nightly for 15 days. They also completed the TSST, a validated paradigm for eliciting social-evaluative threat, and reported their emotion at baseline and immediately post-TSST. Multilevel models examined whether daily and laboratory emotion reactivity were related by testing whether the daily associations between arguments and demands with emotion differed by emotion reactivity to the TSST. Individuals with greater positive emotion reactivity (i.e., greater reductions in positive emotion) and greater negative emotion reactivity to the TSST showed greater positive emotion reactivity to daily demands. Emotion reactivity to the TSST was not significantly related to emotion reactivity to arguments. Findings provide preliminary evidence that emotion reactivity to the TSST relates to some aspects of daily emotion reactivity, with relations differing depending on type of daily stressor and valence of emotion. Results contextualise the implications of emotion reactivity to the TSST for daily stress processes.
