Affect and State Mindfulness
Does individuals personality influence how mindful they are? In a pre-registered experiment, we investigated whether previously established relationships between Neuroticism, Behavioral Inhibition, and mindfulness are due to differences in negative affect reactivity. We expected participants high on Neuroticism/Behavioral Inhibition to show greater negative affect reactivity which in turn would reduce their mindful emotion regulation and self-awareness. We examined the change in mindfulness and affect of 331 participants after exposure to a negative affect stimuli and a distractor task. We found that while negative affect predicted lower Non-Judging and Acting with Awareness, negative affect reactivity did not mediate the relationship between Neuroticism/BIS and the mindfulness facets. Importantly, we only found effects of negative affect on mindfulness facets capturing self-awareness and emotion regulation but not general attention. This indicates that negative affect might shift cognitive resources to threat detection reducing resources available for emotional processing. While our proposed mechanism was not supported, our study holds important implications for clinical practice and future research on individual differences in mindfulness.
