Overview
Brief Summary
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
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.
