Emotional inertia refers to experiencing affective states that are particularly resistant to change. Negative affect inertia is linked to markers of maladjustment and is thus assumed to reflect a form of poor emotional regulation. Recent research using ecological momentary assessment (EMA) data has suggested that emotion regulation strategy use may partially mediate emotional inertia, with certain strategies, such as rumination being associated with the maintenance of a negative affective states. The present study builds on this by providing a replication attempt to examine the mediating effects of rumination, suppression, and reappraisal (Bagnara et al., 2024) as well as an extension to additionally examine the role of acceptance in negative affect inertia.
