Suicide Risk Factors

Risk factors are often confused with warning signs of suicide, and frequently suicide prevention materials mix the two into lists of “what to watch out for.” It is important to note, however, that factors identified as increasing risk are not factors that cause or predict a suicide attempt. Risk factors are characteristics that make it more likely that an individual will consider, attempt, or die by suicide. Protective factors are characteristics that make it less likely that individuals will consider, attempt, or die by suicide.

  • Alcohol and other substance use disorders
  • Hopelessness

  • Previous suicide attempt
  • Family history of suicide
  • Job or financial loss
  • Loss of relationship
  • Easy access to lethal means
  • Local clusters of suicide
  • Lack of social support and sense of isolation
  • Stigma associated with asking for help
  • Lack of health care, especially mental health and substance abuse treatment
  • Cultural and religious beliefs, such as the belief that suicide is a noble resolution of a personal dilemma
  • Exposure to others who have died by suicide (in real life or via the media and Internet)
