Stressor Anticipation and Subsequent Affective Well-Being: A Link Potentially Explained by Perseverative Cognitions

Abstract

Anticipatory stress can prospectively and negatively influence diverse outcomes, including cognitive performance and emotional well-being. It has been suggested that perseverative cognitions (e.g., worry, rumination) during the anticipation period constitute a key mechanism driving these effects. The present study investigated the temporal dynamics among stressor anticipation, perseverative cognitions, and affective well-being. To accurately test the suggested mechanism, we focused on how these dynamics unfold within individuals over time. To that end, we analyzed data from an ecological momentary assessment study in an ethnically diverse sample (N = 243, 25–65 year olds, 68.7% Hispanic or non-Hispanic Black; 14 days, 5 measurement occasions per day) using dynamic structural equation modeling. Anticipating an upcoming stressor was linked to higher levels of perseverative cognitions approximately 3 hours later. At times when individuals reported higher levels of recent perseverative cognitions than typical for them, they also reported higher levels of negative affect and lower levels of positive affect. Mediational modeling indicated that perseverative cognitions accounted for the persistent effects of previous stressor anticipation on negative as well as positive affect several hours later. These findings suggest that perseverative cognitions may play an important role in explaining the detrimental effects of anticipatory stress on subsequent emotional well-being.
