Examination of race-based traumatic stress symptom networks in Black adults in the United States: A network analysis

Abstract

In the United States, racism is theorized to exert its negative effects on Black individuals’ mental health by triggering a response known as “race-based traumatic stress” (RBTS), a multidimensional construct comprising seven clusters of symptoms that can occur following exposure to race-based traumatic events (e.g., racial discrimination, racist incidents): depression, intrusion, anger, hypervigilance, physical symptoms, (low) self-esteem, and avoidance. However, little is known about which symptoms and clusters are strongest and most influential in the maintenance of RBTS. Network analysis is a powerful tool for understanding the etiology of traumatic stress, but it has not yet been applied to the examination of this construct. The present study aimed to identify the symptoms most central to RBTS and examine associations between symptoms and symptom clusters. Participants (N = 1,037) identified as Black, and lived in the United States (M_age = 45.12 years, range: 18–82 years) and completed the Race-Based Traumatic Stress Symptom Scale–Short Form (RBTSSS-SF). Regularized partial correlation networks were estimated using R/RStudio. The cluster- and item-level networks demonstrated adequate centrality stability, CS = .44. The depression and physical symptoms clusters were the most central nodes in the cluster network. Feelings of meaninglessness, experiencing mental images of the event, and physical trembling were the most central items within the item-level network. These findings offer insights and implications for assessing and treating symptoms of RBTS in Black adults in the United States who are exposed to race-based traumatic events.
