Group therapy for women with substance use disorders: results from the Women's Recovery Group Study.

Background: This Stage II trial builds on a Stage I trial comparing the single-gender Women's Recovery Group (WRG) to mixed-gender Group Drug Counseling (GDC) that demonstrated preliminary support for the WRG in treating women with substance use disorders. The Stage II trial aims were to (1) investigate effectiveness of the WRG relative to GDC in a sample of women heterogeneous with respect to substance of abuse and co-occurring psychiatric disorders, and (2) demonstrate the feasibility of implementing WRG in an open-enrollment group format at two sites.

Method: In this randomized clinical trial, participants were included if they were substance dependent and had used substances within the past 60 days (n=158).

Implementing substance abuse group therapy clinical trials in real-world settings: challenges and strategies for participant recruitment and therapist training in the Women's Recovery Group Study.

Background And Objectives: Open-enrollment group therapy research is challenged by the participant recruitment necessary to ensure continuous group enrollment. We present successful strategies to overcome the following barriers during the Women's Recovery Group (WRG) two-site clinical trial (N = 158): maintenance of sample size and balanced gender randomization during continuous enrollment, maintenance of group attendance, and training and retention of therapists over the 24-month continuous group enrollment.

Methods: To increase recruitment, we targeted referral sources yielding the highest enrollment conversion at each site.

Do venlafaxine XR and paroxetine equally influence negative and positive affect?

Background: We assessed the therapeutic effects of venlafaxine XR and paroxetine on mood and anxiety symptoms derived from the tripartite model of mood. We hypothesized that the two antidepressants would have largely similar effects on symptoms of negative affect because both agents influence serotonergic systems. However, based on evidence indicating linkages between catecholaminergic activity and the emotional dimension of positive affect, we hypothesized that the catecholaminergic effects of venlafaxine XR would yield particularly pronounced effects on symptoms of positive affect.
