Certain life events, such as stressful life events, individual psychological factors, or easy access to suicide methods, can facilitate suicide. Therefore, people with a mental disorder or other risk factors may experience suicidal thoughts or behaviors after a precipitating event, such as a humiliating situation (in adolescents), interpersonal tensions (in both adolescents and adults), and social isolation (more common in older adults and adolescents).

The most prevalent precipitating factors are the following:

• An important discussion.
• The breakup or loss of an emotional relationship.
• The suicide of a family member or friend.
• Alcohol or other substance abuse.
• A report on suicide methods.
• The onset or worsening of a mental disorder, physical illness, or accident.
• Unexpected changes in life.
• Experiencing a traumatic life event: abuse, harassment, or violence.
• Loss of social status or respect from others.
