Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine whether computer bias modification for interpretation bias (CBM-I) is effective in the reduction of suicidal ideation in substance use disorders.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Eighty-eight adult inpatients completing residential treatment in the Addictions Services at the Centre for Addiction and Mental Health (CAMH) will be randomized to receive CBM-I daily for one week, adjunct to the residential psychosocial treatment or to an assessment-only control condition. Participants will complete clinical measures consisting of interviews and questionnaires measuring suicidal ideation, hopelessness, depression, negative affect, and interpretation biases before, during and after treatment.

Cognitive Bias Modification

64 training paragraphs, approximately 10-20 seconds each, digitally recorded and presented stereophonically through headphones, delivered over the course of one week.

Group Type EXPERIMENTAL

Cognitive Bias Modification

Intervention Type BEHAVIORAL

Training paragraphs describe scenarios designed to be ambiguous at the outset and to resolve in a positive direction, with the intention of establishing a learning contingency between the ambiguity at the beginning of the scenario and the positive resolution that becomes clear towards the end of the statement.

Assessment-Only Control

No training will be provided.

Group Type NO_INTERVENTION
