Trait Emotion Regulation Predicts Individual Differences in Momentary Emotion and Experience

A sizable literature has yet to establish a reliable empirical connection between the trait conceptualization of emotion regulation as habitual, cross-situation emotion regulation tendencies and its state conceptualization as real-time, fluid, momentary emotion–situation interactivity and dependency. Thus, an open question remains: Do self-reported differences in tendencies to use one or another emotion regulation strategy predict self-reported, momentary emotional states and experiences, and are differences in these emotional states consistent with differences in emotional reactivity observed in previous studies among individuals in experimental paradigms asked to make real-time use of the emotion regulation strategies represented by these trait measures? If trait measures of emotion regulation validly reflect actual uses of particular strategies (e.g., expressive suppression and cognitive reappraisal), then these measures should predict individual differences in momentary emotions and experiences associated with habitual use of these strategies. Examining a sample of 177 participants, we found that differential endorsements of habitual strategy use on these measures were associated with individual differences in self-reported momentary emotion and experience that correspond to well-documented differences in reactivity reported among individuals instructed to apply these strategies in experimental settings. Limitations of these findings and suggestions for future directions are discussed
