Suicide prevention is a vital component of global mental health efforts, aiming to reduce the incidence of self-harm and loss of life through early intervention, support, and evidence-based strategies. It involves identifying risk factors such as depression, trauma, substance abuse, and social isolation, while also strengthening protective factors like resilience, community connection, and access to mental health care. Psychology and psychiatry play central roles in assessing suicide risk, delivering therapeutic interventions, and guiding policy development. Public awareness campaigns, crisis intervention services, and culturally sensitive prevention programs have proven effective in reducing suicide rates. As suicide remains a leading cause of death worldwide, interdisciplinary research and collaboration are essential to developing comprehensive, compassionate, and effective suicide prevention frameworks.
