This paper suggested that both positive and negative family factors can impact adolescent suicide rates. Supportive relationships with parents, siblings, and other family members can provide a sense of belonging, connection, and emotional support that can help to protect adolescents from suicidal thoughts and behaviors. Studies have found that adolescents who are exposed to these types of adverse family experiences are more likely to experience depression, anxiety, and other mental health problems, which can increase their risk of suicide. The research presented in this article suggests that family environment continues to be one of the most important factors influencing adolescent suicide rates, with the two groups most at risk for suicide having much higher levels of exposure to domestic violence and substance abuse. No significant changes were found in age, academic achievement, race, or family structure. This suggests that the most influential determinants of adolescent suicide rates are family environment, followed by gender and prior exposure to suicide. The purpose of this literature review on adolescent suicide is to provide a comprehensive overview of existing research on the influence of relationships and family on adolescent suicide rates, highlight key findings and identify areas for further research.
