The Association of Daily Stressors and Daily Emotions to Daily Optimism

Abstract

Abstract. Daily life events often trigger and co-occur with various emotional reactions, which activate self-regulatory processes. One possible outcome of self-regulatory processes is optimism. Limited research has examined optimism in daily life and potential daily predictors, including stressors, negative emotions, and positive emotions. Emotion differentiation – the ability to identify and label discrete emotional states – has the potential to change the association between daily predictors and optimism. The current study contextualized optimism in the emotion-laden daily life and examined the association of daily stressors and daily negative and positive emotional states to daily optimism and the role of negative and positive emotion regulation on these relationships. The current study adopted a daily diary design and collected self-reported daily responses from a sample of 248 college students over a 7-day study period. The results included concurrent and lagged effects and showed that daily negative affect and positive affect predicted both concurrent daily optimism and the next day’s optimism. Greater negative emotion differentiation predicted higher daily optimism. A better ability to differentiate positive emotions predicted a stronger relation between positive affect and daily optimism. The findings underscored the importance of daily affect and emotion differentiation being important markers for optimism interventions and daily practices.
