Outcomes
| Outcome 1: Substance abuse |
|
Description of Measures
|
Substance use was measured by urinalysis and structured interviews. Interview assessments included the Timeline Followback Interview (TLFB), which determines drinking and other drug use over a specified time period. Substance use also was measured with the substance use modules of the Structured Clinical Interview for DSM-IV (SCID). Some studies used the Drinker Inventory of Consequences (DrInC), a 45-item self-report measure. In some studies, researchers assessed substance use with the Addiction Severity Index (ASI), a 45-minute semistructured interview.
|
|
Key Findings
|
In evaluations using randomized controlled trials, male BCT clients improved significantly more than clients in individual-based therapy and/or attention control groups on measures of substance abuse. BCT clients who used opioids had more drug-free urine samples and self-reported days of alcohol and drug abstinence over the course of treatment and up to 1 year after completing treatment (p < .05). Among BCT clients on methadone maintenance, similar results at the end of treatment were obtained for cocaine and opiates, as measured by urine screens and by Addiction Severity Index scores (p < .05).
Among women with alcoholism, BCT participants reported fewer days of drinking (p < .01) and fewer drinking-related consequences (p < .05) at 1-year follow-up, compared with those receiving alternative care.
Among men in treatment for substance abuse, other benefits reported for BCT compared with alternative care included more days of abstinence at 6-month follow-up and fewer inpatient substance abuse treatment admissions and fewer alcohol-related arrests at 1-year follow-up. Among women, benefits reported for BCT included fewer substance-related problems at the end of treatment and fewer days of substance use and longer continuous abstinence 9 months after treatment.
One evaluation found BCT is more cost-effective than individual-based therapy over the year following treatment for substance abuse.

| Outcome 2: Quality of relationship with intimate partner |
|
Description of Measures
|
The quality of the relationship with the intimate partner was measured by standardized self-report measures. Some studies used the Dyadic Adjustment Scale (DAS), a 32-item self-report measure. Measures also included the 10-item Marital Happiness Scale (MHS); the Locke-Wallace Marital Adjustment Test (MAT), a 15-item self-report measure of general relationship satisfaction; the Areas of Change Questionnaire (ACQ), in which each partner notes on a 7-point scale how much partner change is desired in 34 common relationship behaviors; and the Responses to Conflict Scale (RTC), a 12-item scale of frequency of response occurrence.
|
|
Key Findings
|
In randomized controlled trials, BCT clients indicated better intimate partner relationship outcomes than clients in comparison conditions. In some studies, the benefits of BCT appeared to dissipate after 6 months; in others, BCT clients at 1-year follow-up showed a smaller decline in relationship satisfaction than recipients of alternative care.

|
Description of Measures
|
Treatment retention was measured by clinical records.
|
|
Key Findings
|
Among men receiving treatment for opiate use, BCT participants ingested more naltrexone (p < .01) and attended more scheduled treatment sessions (p < .05) than participants in individual-based treatment.

| Outcome 4: Intimate partner violence |
|
Description of Measures
|
Intimate partner violence was measured by the Timeline Followback Interview on Spousal Violence, which assesses the percentage of days in a target interval when spousal violence occurred, and the Conflict Tactics Scale (CTS) verbal aggression and violence subscales, which assess prevalence and frequency of verbal aggression, overall violence, and severe violence over the past 12 months.
|
|
Key Findings
|
Two years posttreatment, indicators of verbal and physical aggression with intimate partners declined among male BCT clients with alcoholism. The rate of severe partner violence among the clients dropped to that of a matched sample of nonalcoholic men in the first year posttreatment; the rate of any violence dropped to that of the matched sample by the end of the second year.
An evaluation of women with alcoholism who participated in BCT found lower rates of violence after 1 year than among participants in alternative care.

| Outcome 5: Children's psychosocial functioning |
|
Description of Measures
|
Children's psychosocial adjustment was measured by the Pediatric Symptom Checklist (PSC). The PSC is a 35-item questionnaire on emotional and behavioral problems.
|
|
Key Findings
|
Parents who participated in BCT reported higher psychosocial functioning in their children than recipients of alternative care at posttreatment and at 6- and 12-month follow-ups (p < .001). In addition, the percentage of children of couples in BCT with clinical impairment declined from 32% at baseline to 5% at 12-month follow-up (p < .001).

Study Strengths Recent studies document treatment fidelity and employ sophisticated approaches to handling missing data and attrition. Studies generally used successful random assignments. Measures used were psychometrically sound and reflected the state of the science. Analytic plans were generally well described and justified, and exhaustive assessments minimized confounds. Intervention fidelity was well described and measured in several studies.
Study Weaknesses Not all studies minimized confounds with randomized controlled trials. Some small data sets were analyzed more than once and may have been underpowered. Some studies lacked documentation of intervention fidelity or the approach to handling missing data and attrition.
