Suicide attempts involving drug abuse are a major public health problem. Development of interventions that focus on reducing the suicide attempt rate among drug abusers is a necessity. There is a strong connection between drug abuse and both suicide attempts and completed suicide. As much as 45% of drug abusers have attempted suicide at least once. The rate of completed suicide among drug abusers has been reported to be as much as 30 times the rate for the general population. Unfortunately, there is a lack of empirically supported treatments for reducing suicidal behavior in drug abusers. This study will develop and evaluate the effectiveness of a cognitive therapy intervention for people with a drug dependence disorder who recently attempted suicide.
