Risk and Protective Factors
Suicide prevention seeks to reduce the factors that increase suicide risk while increasing the factors that protect people from suicide.
Risk factors are characteristics of a person or his or her environment that increase the likelihood that he or she will die by suicide (i.e., suicide risk).
Major risk factors for suicide include:
- Prior suicide attempt(s)
- Misuse and abuse of alcohol or other drugs
- Mental disorders, particularly depression and other mood disorders
- Access to lethal means
- Knowing someone who died by suicide, particularly a family member
- Social isolation
- Chronic disease and disability
- Lack of access to behavioral health care
Risk Factors Can Vary Across Groups
Risk factors can vary by age group, culture, sex, and other characteristics. For example:
- Stress resulting from prejudice and discrimination (family rejection, bullying, violence) is a known risk factor for suicide attempts among lesbian, gay, bisexual, and transgender (LGBT) youth.
- The historical trauma suffered by American Indians and Alaska Natives (resettlement, destruction of cultures and economies) contributes to the high suicide rate in this population.
- For men in the middle years, stressors that challenge traditional male roles, such as unemployment and divorce, have been identified as important risk factors.
Protective factors are personal or environmental characteristics that help protect people from suicide.
Major protective factors for suicide include:
- Effective behavioral health care
- Connectedness to individuals, family, community, and social institutions
- Life skills (including problem solving skills and coping skills, ability to adapt to change)
- Self-esteem and a sense of purpose or meaning in life
- Cultural, religious, or personal beliefs that discourage suicide
