Most people who have the risk factors for suicide will not kill themselves. However, the risk for suicidal behavior is complex. Research suggests that people who attempt suicide may react to events, think, and make decisions differently than those who do not attempt suicide. These differences happen more often if a person also has a disorder such as depression, substance abuse, anxiety, borderline personality disorder, and psychosis. Risk factors are important to keep in mind; however, someone who has warning signs of suicide may be in more danger and require immediate attention.
