Predictors of treatment retention for substance-dependent adults with co-occurring depression.

Low attendance in addiction treatment, particularly in cases of comorbidity, has been identified as a pervasive challenge. We examine predictors of treatment retention in a sample of veterans (N = 253) participating in a clinical trial comparing two types of psychotherapy for co-occurring depression and substance use disorders. The study protocol included 24 weeks of outpatient group psychotherapy in either a newly developed Integrated Cognitive Behavioral Therapy (ICBT) or Twelve-Step Facilitation Therapy (TSF).

Neuropsychological functioning and outcomes of treatment for co-occurring depression and substance use disorders.

Background: We previously published findings from our clinical trial comparing treatment outcomes for substance-dependent veterans with co-occurring depression who received Integrated Cognitive Behavioral Therapy (ICBT) or Twelve-Step Facilitation (TSF) Therapy.

Objectives: This study is a secondary analysis that examined whether neuropsychological functioning at baseline moderated substance use and depression outcomes in ICBT relative to TSF.

Methods: This study was a randomized clinical trial in which 164 veterans with major depressive disorder and comorbid alcohol, cannabinol, and/or stimulant dependence were randomly assigned to either ICBT or TSF group therapy.

Comorbidity of substance dependence and depression: role of life stress and self-efficacy in sustaining abstinence.

The authors examined life stress and self-efficacy as predictors of time to relapse for 113 adults with comorbid major depressive disorder and alcohol and/or substance dependence in a randomized clinical trial comparing 2 psychotherapy interventions (integrated cognitive- behavioral therapy and 12-step facilitation therapy). Life stress, self-efficacy, and substance use were assessed at treatment entry, 12 weeks (mid-treatment), and 24 weeks (end of treatment). Time to relapse was defined as the number of days from treatment initiation until first alcohol and/or drug use.
