Among people with suicidal thoughts, the risk of making a suicide attempt was strongest among those with substance abuse and impulse control disorders, which suggests these disorders are most strongly associated with acting on suicidal thoughts.
The study also found that among people with suicidal thoughts, 29 percent later made a suicide attempt, and these attempts were most common within the first year after the onset of suicidal thoughts.
Among people with both suicidal thoughts and a plan, there was a 56 percent probability of a suicide attempt, compared with 15.4 percent among those without a plan.
The study looked at 84,850 adults in Nigeria, South Africa, Colombia, Mexico, the United States, Japan, New Zealand, China, Belgium, France, Germany, Italy, the Netherlands, Spain, Ukraine, Israel and Lebanon.
Suicide is a leading cause of death worldwide. This is the first study to examine the suicidal thoughts and behaviors of people in numerous and diverse countries.
Mental Health America has more about suicide.
