A combination of individual, relationship, community, and societal factors contribute to the risk of suicide. Risk factors are those characteristics associated with suicide—they might not be direct causes.
Risk Factors
Family history of suicide
Family history of child maltreatment
Previous suicide attempt(s)
History of mental disorders, particularly clinical depression
History of alcohol and substance abuse
Feelings of hopelessness
Impulsive or aggressive tendencies
Cultural and religious beliefs (e.g., belief that suicide is noble resolution of a personal dilemma)
Local epidemics of suicide
Isolation, a feeling of being cut off from other people
Barriers to accessing mental health treatment
Loss (relational, social, work, or financial)
Physical illness
Easy access to lethal methods
Unwillingness to seek help because of the stigma attached to mental health and substance abuse disorders or to suicidal thoughts
Protective factors buffer individuals from suicidal thoughts and behavior. To date, protective factors have not been studied as extensively or rigorously as risk factors. Identifying and understanding protective factors are, however, equally as important as researching risk factors.
Protective Factors
Effective clinical care for mental, physical, and substance abuse disorders
Easy access to a variety of clinical interventions and support for help seeking
Family and community support (connectedness)
Support from ongoing medical and mental health care relationships
Skills in problem solving, conflict resolution, and nonviolent ways of handling disputes
Cultural and religious beliefs that discourage suicide and support instincts for self-preservation
