Comparing characteristics of suicide attempters with suicidal ideation and those without suicidal ideation treated in the emergency departments of general hospitals in China.

Suicide attempts are more frequent than suicides, and suicidal ideation has been identified as an important precursor of both attempted and completed suicide. In this study, we compare the characteristics of suicide attempters with suicidal ideation and suicide attempters without suicidal ideation who were treated in the emergency departments of general hospitals in China. We identified 166 people as having suicidal ideation and 73 people who did not have suicidal ideation. The suicide attempters with suicidal ideation were more likely to be more depressed, older, have a lower score on life quality, female, divorced and unemployed, report having religious beliefs, have a suicide attempt history and a psychiatric diagnosis, and intend to reduce pain as motives. However, the suicide attempters without suicidal ideation were more likely to have a more self-rescue ideation and were more impulsive, and to threaten or intend revenge on others as motives. Multivariate logistic regression analysis identified the following independent predictors of suicidal ideation in the suicide attempters: a higher score on Hamilton Depression Rating Scale, religious beliefs, non-impulsive suicide attempts, and a psychiatric diagnosis. The results indicate the importance of developing different interventions for the two groups to prevent future suicide in China.
