Introduction

The purpose of this study is to report the prevalence of youth lifetime exposure to suicide attempts by people close to them, and its association with personal nonvictimization adversities, suicidal ideation, thoughts of self-harm, and trauma symptoms.

Methods

Data were collected as part of the National Surveys of Children's Exposure to Violence, comprising three cross-sectional studies conducted in 2008, 2011, and 2014 in the U.S. assessing the experiences of children ages 1 month to 17 years. The current analyses utilized the self-report data from youth, ages 10–17 years (n=6,366), and was analyzed in 2017.

Results

Twelve percent (n=779) of youth said someone close to them had tried to kill themselves. Exposure varied by age: 4% of youth aged 10–12 years, 13% of youth aged 13–15 years, and 21% of youth aged 16–17 years reported such exposure. Exposure to suicide attempts also varied by sex with 8% of males and 16% of females reporting this experience. After adjusting for the total number of other types of adversity experienced, the association between exposure to suicide attempts and trauma symptoms (β=0.5, 95% CI=0.3, 0.7, p≤0.001); suicidal ideation (OR=2.4, 95% CI=1.4, 4.1, p≤0.001); and thoughts of self-harm (OR=3.1, 95% CI=1.9, 5.1, p≤0.001) remained significant, although attenuated.

Conclusions

Study findings that youth exposure to suicidal behavior is associated with negative emotional distress, and that it often co-occurs with other adversities and social risk factors, highlight the need to better understand the causal pathways among these risk factors to improve youth suicide prevention and response interventions.
