Identifying Latent Profiles of Emotion Dysregulation in a Trauma-Exposed Sample Pubblico

Abstract

Emotion dysregulation is a multifaceted transdiagnostic risk factor for the development and maintenance of psychopathology. Person-centered analyses can be used to identify distinct profiles of emotion dysregulation based on individuals’ response patterns, which cannot be investigated using variable-centered analyses. Previous studies have uncovered emotion dysregulation profiles that are differentially associated with psychological outcomes. However, a lack of investigation into predictors, a narrow scope of distal outcomes, and underrepresentation of racial minorities limit the current literature. To address these gaps, we used latent profile analysis to uncover unique patterns of emotion dysregulation, examine the role of childhood maltreatment in predicting profile membership, and examine differences in internalizing and externalizing symptoms in a trauma-exposed community sample (n = 783, 97% Black). Participants were recruited from medical clinics of an urban public hospital and completed a battery of self-report measures assessing emotion dysregulation, trauma exposure, and psychological symptoms. The best-fitting model uncovered four classes: Regulators (42%), Managers (34%), Dwellers (17%), and Dysregulators (6%). Childhood maltreatment history predicted class membership, such that those who experienced more severe maltreatment were more likely to be classified in the Dwellers and Dysregulators profiles. All classes differed in terms of internalizing symptoms (anxiety sensitivity, depression, PTSD), with classes characterized by higher emotion dysregulation reporting greater symptomatology. For externalizing symptoms (food addiction behaviors, alcohol and drug abuse, aggressive behavior), the Regulators were lower than all other profiles. Thus, patterns of emotion dysregulation ought to be assessed and considered as treatment targets for those experiencing internalizing and externalizing psychopathological symptoms.
