Neuroticism, extraversion, emotion regulation, negative affect and positive affect: The mediating roles of reappraisal and suppression

The associations between extraversion and positive affect and between neuroticism and negative affect are well documented (e.g., Diener, Oishi, & Lucas, 2003). However, it is still unclear why the extraversion-positive affect and neuroticism-negative affect relationships are so close. Based on the findings from emotion regulation research (e.g., John & Gross, 2004), the mediating roles of two emotion regulation strategies - reappraisal and suppression - between the two personality dimensions and positive and negative affect were examined in this study.
