Violence exposure, posttraumatic stress, and affect variability among African American Youth: A time sampling approach

Abstract The current study examines the immediate and short-term impact of daily exposure to community violence on same-day and next-day levels of posttraumatic stress symptomatology and various affective states (i.e., dysphoria, hostility, and anxiety), in a sample of 268 African American adolescents living in urban, low-income, high-violence neighborhoods (Mage = 11.65; 59% female). In addition, the moderating role of affective state variability on this relationship was examined. This study utilized experience sampling method and a daily sampling approach, which contributes a more robust investigation of the short-term effects of violence exposure in youth. Hierarchical linear modeling revealed that community violence exposure was positively associated with same-day and next-day symptoms of posttraumatic stress. Violence exposure also exhibited an immediate effect on dysphoria, anxiety, and hostility levels. Youth variability in dysphoria exacerbated the effect of violence exposure on concurrent or next-day posttraumatic stress, dysphoria, and hostility. Moreover, variability in anxiety and hostility exacerbated the experience of next-day hostility. The clinical implications relating to these findings, such as the importance of implementing screening for posttraumatic stress following exposure, the incorporation of preventative treatments among those at risk of exposure, and the targeting of emotion regulation in treatments with adolescents, are discussed.
