Alone in the aftermath: A nationwide prospective study on the role of loneliness in depression-driven suicidal ideation following the October 7, 2023, terrorist attack

Findings highlight the compounding effect of depression and loneliness on suicide ideation in the aftermath of mass trauma. The results suggest that loneliness may act as a critical mechanism that sustains suicidality by reinforcing isolation and limiting access to emotional support. This study underscores the need for trauma-informed suicide prevention strategies that incorporate interventions aimed at reducing loneliness, enhancing interpersonal connectedness, and promoting social reintegration.
