Protective Factors Associated with Daily Affective Reactivity and Instability During Adolescence

Affective reactivity to daily stressors is associated with elevated inflammation.

OBJECTIVE Inflammation increases the risk of chronic diseases, but the links between emotional responses to daily events and inflammation are unknown. We examined individual differences in affective reactivity to daily stressors (i.e., changes in positive and negative affect in response to stressors) as predictors of inflammatory markers interleukin-6 (IL-6) and C-reactive protein (CRP). METH...

Health Psychology Affective Reactivity to Daily Stressors Is Associated With Elevated Inflammation

Socioeconomic status, daily affective and social experiences, and inflammation during adolescence.

OBJECTIVE To assess the relation between socioeconomic status (SES) and inflammation during adolescence and determine whether daily affective and social experiences across a 15-day period mediate this relation. METHODS Adolescents (n = 316) completed daily diary reports of positive affect, negative affect, and negative social interactions for 15 days and provided whole blood spot samples for ...

Physical activity and negative affective reactivity in daily life.

OBJECTIVE The results from experimental studies indicate that physically active individuals remain calmer and report less anxiety after the induction of a standardized stressor. The current study extends this research to real life, and examines whether daily physical activity attenuates negative affect that occurs in response to naturally occurring daily stressors. METHOD The current study us...
