Experiencing stress is all too common. Although stressful experiences can have deleterious effects on individual well-being in a variety relationships and settings, romantic partners are in a unique position to regulate each other’s emotions during times of distress. To understand couples’ interpersonal emotion regulation, Ashley Randall uses multi-method approaches (e.g., self-report, daily diary, momentary measures of emotional experience, and behavioral observations) and advanced statistical analyses suitable for longitudinal dyadic data analysis. To date, her empirical investigations have: (a) defined constructs related to stress in close relationships and couples’ interpersonal emotion regulation, (b) examined couples’ automatic and deliberate regulation processes, and (c) analyzed resulting associations with mental health outcomes.
