The Women's Recovery Group Study: Stage I Trial

Phase 1

Completed

Conditions: Alcohol-Related Disorders
Substance-Related Disorders

Registration Number: NCT00230100

Lead Sponsor: Mclean Hospital

Brief Summary: The purpose of this study was to develop a gender-specific 12-session, manual-based relapse prevention group for women with substance use disorders (SUDs).

Detailed Description: This Phase I trial compares single-gender Women's Recovery Group (WRG) and an effective control condition, mixed-gender Group Drug Counseling (GDC). WRG is a new 12-session women-focused, manual-based relapse-prevention group therapy that uses a cognitive-behavioral approach. It is a 90-minute structured relapse prevention weekly group therapy with both women-focused content as well as an all-women group composition. The control condition, Group Drug Counseling (GDC), consists of 12 weekly 90-minute structured sessions and is conducted in a mixed-gender group composition and has no women-focused content. The GDC was chosen as the comparison group to approximate group drug counseling that is consistent with treatment as usual within the community. Both groups stress abstinence. Women are randomly assigned to one of the two conditions and the groups are conducted in a rolling group, semi-open format.

The treatment manual for a Women's Recovery Group (WRG) focused on the themes that are relevant to women with SUDs. There was an emphasis on educating patients about treatment and relapse prevention in a context that is relevant to women. The manual combined therapist information and instructions with patient worksheets, handouts and skills practices. The treatment intervention was conducted twice in a pre-pilot study led by study investigators. The investigators then conducted a pilot study in which outcomes among subjects receiving the treatment intervention were compared with outcomes of subjects who received the standard mixed-gender Group Drug Counseling (GDC), chosen to approximate treatment in the community.

The study hypothesis was that the single-gender group composition and women-focused group content would result in better treatment outcomes, including decrease number of days of substance use compared with baseline during follow-up, reduced substance use, and lengthened time to relapse, compared with the mixed-gender control.

Primary Outcome Measures

Name	Time	Method
Change in Mean Days of Any Substance Use for Women	In-treatment phase (month 1-3), Post-treatment phase (month 4-6, 9)	This represents the change from baseline in the mean number of days per month of any substance use (i.e. drug and/or alcohol). Days of substance use was assessed using the Timeline Follow-Back at baseline (assessing for the 60 days prior to the baseline interview) and then monthly for months 1-6 (months 1-3 were in-treatment assessments and months 4-6 were post-treatment follow-up assessments), and month 9 (also a post-treatment follow-up assessment). We implemented a general mixed model analysis of variance (MMANOVA), which models the means per group over the respective time period and the covariance between the repeated measures over the assessments. Both the in-treatment and post-treatment time frames were compared to baseline substance use data.
Change in Mean Number of Drinking Days for Women	In-treatment phase (month 1-3), Post-treatment phase (month 4-6, 9)	This represents the change from baseline in the mean number of drinking days for women. Number drinking days was assessed using the Timeline Follow-Back at baseline (assessing for the 60 days prior to the baseline interview) and then monthly for months 1-6 (months 1-3 were in-treatment assessments and months 4-6 were post-treatment follow-up assessments), and month 9 (also a post-treatment follow-up assessment). We implemented a general mixed model analysis of variance (MMANOVA), which models the means per group over the respective time period and the covariance between the repeated measures over the assessments. Both the in-treatment and post-treatment time frames were compared to baseline substance use data.

Secondary Outcome Measures

Name	Time	Method
Change in Mean Addiction Severity Index Alcohol Composite Score for Women	In-treatment phase (month 1-3), Post-treatment phase (month 4-6, 9)	This represents the change from baseline in mean composite scores of the Addiction Severity Index (ASI) alcohol section. The ASI was administered at baseline (assessing for the 60 days prior to the baseline interview) and then monthly for months 1-6 (months 1-3 were in-treatment assessments and months 4-6 were post-treatment follow-up assessments), and month 9 (also a post-treatment follow-up assessment). We implemented a general mixed model analysis of variance (MMANOVA), which models the means per group over the respective time period and the covariance between the repeated measures over the assessments. Both the in-treatment and post-treatment time frames were compared to baseline substance use data. The ASI is a widely employed multidimensional assessment of substance-related problems. Scores range from 0-1 where higher scores reflect higher addiction severity.
Change in Mean Number of Drinks Per Drinking Day for Women	In-treatment phase (month 1-3), Post-treatment phase (month 4-6, 9)	This represents the change from baseline in the mean number of drinks per drinking day for women. The number of drinks per drinking day was measured using the Timeline Follow-Back at baseline (assessing for the 60 days prior to the baseline interview) and then monthly for months 1-6 (months 1-3 were in-treatment assessments and months 4-6 were post-treatment follow-up assessments), and month 9 (also a post-treatment follow-up assessment). We implemented a general mixed model analysis of variance (MMANOVA), which models the means per group over the respective time period and the covariance between the repeated measures over the assessments. Both the in-treatment and post-treatment time frames were compared to baseline substance use data.
