This study examines how social networks, encompassing interactions across family, peers, school, and neighborhoods, can influence suicidal behaviors and prevention strategies among adolescents transitioning into adulthood. Using data from the National Longitudinal Study of Adolescent to Adult Health, the research identified different trajectories of suicidal ideation and attempts among 9,421 high school students over several years.
Key findings include:
- Three trajectories of suicidal ideation (low-stable, high-decreasing, moderate-decreasing-increasing) and two trajectories of suicide attempts (low-stable, moderate-decreasing) were identified.
- Family cohesion played a significant protective role, reducing the likelihood of adolescents belonging to high-risk trajectories of suicidal ideation and attempts.
- The impact of social networks varied across racial/ethnic groups, sexes, sexual identities, and socioeconomic statuses, highlighting important moderation effects.
- Quality of interactions within social networks (such as household cohesion, peer support, and neighborhood support) emerged as crucial factors in identifying and preventing suicidal behaviors over time.
This study underscores the importance of understanding and leveraging social networks in suicide prevention efforts. Enhancing family cohesion and fostering supportive peer and neighborhood relationships can play pivotal roles in mitigating suicidal tendencies among adolescents and young adults.
