Suicidal behavior is a multidimensional phenomenon that includes thoughts of suicide, suicide attempts, and completed suicides. It is a serious public health issue with complex and multifaceted causes, including mental health disorders, substance abuse, interpersonal conflict, and socioeconomic factors. Research in this area aims to understand the risk factors, warning signs, and protective factors associated with suicidal behavior, as well as to develop strategies for prevention, intervention, and treatment. Studies in this field examine the psychological, social, and biological factors that contribute to suicidal behavior and strive to improve identification and support for individuals at risk. Ultimately, the goal of research on suicidal behavior is to reduce the incidence of suicide and promote mental health and well-being.
