Factors that affect substance users' suicidal behavior: a view from the Addiction Severity Index in Korea.
BACKGROUND
In South Korea, it has not been easy to negotiate studies that target drug users who are being punished by law, and accordingly, no study on suicidal ideation among substance users has been accomplished yet. In this study, the factors that affect substance users' suicidal ideation were confirmed.


METHODS
It was based on the data collected from 'The 2009 Study on Substance-Dependent Individuals in Korea' , which was conducted by The Catholic University of Korea in 2010 as a project sponsored by the Ministry of Health and Welfare of Korea. This study targeted 523 former hospital inpatients, prison inmates, and persons under protective supervision who had used substances such as psychotropic drugs, marijuana, and narcotic agents, and were in the recovery stage at various treatment/rehabilitation centers. Student's t and chi-square tests were used, and multivariate analysis was performed to examine the strength of the relationships between suicide ideation and various factors.


RESULTS
According to this study, 41% of these substance users planned suicide with suicidal ideation. Suicidal ideation was confirmed as associated with an unsatisfactory domestic environment, insufficient and unsatisfactory spare time experiences with others, emotional abuse, severe depression, and trouble with controlling violent behavior. Of the substance users who had planned to commit suicide, 56% attempted suicide. Their suicide attempts were shown to have been associated with insufficient protective supervision and the experiences of physical abuse, trouble with controlling violent behavior, and doctors' prescriptions due to psychological or emotional problems.


CONCLUSIONS
Based on this analysis of the factors that affect suicidal behavior, preventive measures and strategies for substance user were suggested in this study.
