Effectiveness of Cognitive Therapy for Suicide Attempters With Drug Dependence Disorder

Phase 1

Completed

• Conditions: Suicide, Attempted; Substance-Related Disorders
• Interventions: Behavioral: Cognitive Therapy; Other: Enriched Care

• Registration Number: NCT00218725
• Lead Sponsor: University of Pennsylvania

Brief Summary

This study will examine the effectiveness of combining cognitive therapy with enriched usual care for preventing subsequent suicide attempts in people with a drug dependence who have recently attempted suicide.

Detailed Description

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.

Participants in this single-blind study will be randomly assigned to one of two treatment groups: cognitive therapy combined with enriched usual care; or enriched usual care alone. An initial baseline assessment will occur within 7 days following the participant's suicide attempt and subsequent medical evaluation at a hospital emergency department. Suicide behavior and ideation, depression, hopelessness, and addiction severity will be assessed. Following the baseline assessment, treatment will begin. The cognitive therapy treatment will be specifically developed to prevent suicide attempts. It will involve the identification of proximal thoughts, images, and core beliefs that were activated prior to the suicide attempt. Cognitive and behavioral strategies will be applied to address the identified thoughts and beliefs. Patients will also learn adaptive ways of coping with stressors. The enriched usual care will entail standard treatments for suicide prevention. Study visits will occur 1, 3, 6, 12, 18, and 24 months following enrollment. Baseline measurements will be repeated at each study visit to evaluate participants' improvement. Participants receiving cognitive therapy will attend approximately 10 weekly or bi-weekly outpatient study visits. Participation will last for 2 years.

Arm && Interventions

Group	Intervention	Description
Cognitive Therapy	Cognitive Therapy	The cognitive therapy intervention for suicide attempters has been designed to provide a brief, timely, flexible intervention that can be incorporated into general and psychiatric inpatient and outpatient services and applied to the population of patients who attempt suicide. A central feature of the intervention is the adaptation of cognitive therapy to the population of patients who attempt suicide. The focus of the intervention is the identification of core beliefs and key automatic thoughts that were elicited prior to and during the most recent suicide attempt. Once these beliefs and thoughts have been articulated, the counselor and patient develop more adaptive responses during an acute suicidal crisis.
Enriched Care	Enriched Care	The Enriched Care condition will be used as the treatment comparison condition for this study. The Enriched Care condition consists of the usual care that patients may obtain in the community as well as the assessment and referral services provided by the case managers. Participation in the study does not restrict patients in any way in their access to other health care, and all patients in both conditions will be allowed to receive any additional mental health and substance abuse treatment in the community.
