Résumé

Proliferation of the term “emotion dysregulation” in child psychopathology parallels the growing interest in processes that influence negative emotional reactivity. While it commonly refers to a clinical phenotype where intense anger leads to behavioral dyscontrol, the term implies etiology because anything that is dysregulated requires an impaired regulatory mechanism. Many cognitive, affective, behavioral, neural, and social processes have been studied to improve understanding of emotion dysregulation. Nevertheless, the defective regulatory mechanism that might underlie it remains unclear. This systematic review of research on processes that affect emotion dysregulation endeavors to develop an integrative framework for the wide variety of factors investigated. It seeks to ascertain which, if any, constitutes an impaired regulatory mechanism. Based on this review, we propose a framework organizing emotion‐relevant processes into categories pertaining to stimulus processing, response selection and control, emotion generation, closed‐ or open‐loop feedback‐based regulation, and experiential influences. Our review finds scant evidence for closed‐loop (automatic) mechanisms to downregulate anger arousal rapidly. Open‐loop (deliberate) regulatory strategies seem effective for low‐to‐moderate arousal. More extensive evidence supports roles for aspects of stimulus processing (sensory sensitivity, salience, appraisal, threat processing, and reward expectancy). Response control functions, such as inhibitory control, show robust associations with emotion dysregulation. Processes relating to emotion generation highlight aberrant features in autonomic, endocrine, reward functioning, and tonic mood states. A large literature on adverse childhood experiences and family interactions shows the unique and joint effects of interpersonal with child‐level risks. We conclude that the defective closed‐loop regulatory mechanisms that emotion dysregulation implies require further specification. Integrating research on emotion‐relevant mechanisms along an axis from input factors through emotion generation to corrective feedback may promote research on (a) heterogeneity in pathogenesis, (b) interrelationships between these factors, and (c) the derivation of better‐targeted treatments that address specific pathogenic processes of affected youth.
