Indirect violence exposure and mental health symptoms among an urban public-school population: Prevalence and correlates.

Available literature identifies the need for a deeper understanding of the role of gender, age and socioeconomic status in children's exposure to violence and associations with mental health (MH) outcomes. The 1548 participants for this study were enrolled from 28 public charter schools and 9 community-based settings; youth were administered a screener that assessed exposure to traumatic events and symptoms of post-traumatic stress disorder (PTSD) and depression. Respondents reported extremely high levels of exposure to indirect violence: 41.7% witnessed shooting/stabbing/beating; 18.3% witnessed murder; and 53.8% experienced the murder of someone close. Frequency of adverse MH outcomes was high: 21.2% screened positive for depression; 45.7% for lifetime PTSD; and 26.9% for current PTSD. More males than females reported witnessing shooting/stabbing/beating (p = .04); females more often reported experiencing the murder of someone close (p = .001). Indirect violence exposure generally increased with age. Youth attending schools with ≥90% free/reduced lunch participation (FRLP) showed significantly higher levels of violence exposure compared to youth in schools with <90% FRLP. Females endorsed significantly higher levels of depression (21.4% vs. 9.7%), and lifetime (53.9% vs. 34.9%) and current (32.5% vs. 19.6%) PTSD, compared with males (p < .0001, all comparisons). Female sex (aOR = 2.6), FRLP (aOR = 1.4 for ≥90% vs.
