The present study explores the role of (1) “experiential avoidance” (being non-accepting towards mental events) and (2) “mindful awareness” (being attentive in the present moment) in the prediction of well-being. These established constructs are newly complemented with (3) “meta-emotions” (emotional reactions about one’s own emotions) that allow for a meaningful differentiation of processes in experiential avoidance. Psychometric properties of the newly developed Meta-Emotion Scale (MES) are presented. Psychological well-being is strongly predicted by all three facets. Of the six MES subscales, substantial predictive power could be confirmed for “contempt/shame”, “suppression”, “tough control” and “interest”, whereas “anger” and “compassionate care”, unexpectedly, exerted little influence in our non-clinical sample. The role of meta-emotions in emotion regulation is discussed.
