Drug Abuse Treatment Process Components that Improve Retention

BACKGROUND Longer retention has been the most consistent predictor of favorable drug abuse treatment outcomes, but key therapeutic and patient engagement indicators of treatment process need to be more clearly established. METHODS An integrative model representing treatment dynamics was tested for explaining long-term program retention. It was based on a multisite sample of 527 daily opioid users who remained in methadone maintenance a minimum of 3 months. All had been assigned randomly to a counseling condition at admission (i.e., cognitively enhanced or standard), and information obtained from patient files, as well as periodic assessments completed by patients and their counselors in the first 90 days after admission were the sources of predictors. RESULTS Counseling enhancements (using node-link mapping, a visual representation tool for improving communication and problem solving) contributed to stronger therapeutic relationships between counselor and patient, which in turn had a positive reciprocal relationship with patient engagement (session attendance). Pretreatment motivation measured at intake was also related to higher engagement. More positive therapeutic relationships (in months 1 and 2) led to lower levels of during-treatment drug use (defined from urinalysis results in months 2 and 3), and better session attendance and therapeutic relationships both predicted longer retention. In addition, lower drug use during treatment was related to longer retention. CONCLUSIONS Major conceptual domains of drug abuse treatment process were identified in community-based programs and their interrelationships with retention specified. As intermediate (during treatment) criteria, they can help guide functional improvements in program effectiveness as illustrated with our counseling enhancements.

Retention and patient engagement models for different treatment modalities in DATOS.

A model to explain treatment retention in terms of process components--therapeutic involvement and session attributes for the 1st month--and patient background factors were tested in long-term residential (LTR), outpatient drug free (ODF), and outpatient methadone (OMT) treatments. The data was collected in the national Drug Abuse Treatment Outcome Studies (DATOS), and included 1362 patients in LTR, 866 in ODF, and 981 in OMT programs. Structural equation models showed there were positive reciprocal effects between therapeutic involvement and session attributes in all three modalities, and these variables had direct positive effects on treatment retention. Motivation at intake was a strong determinant of therapeutic involvement. Other patient background factors were significantly related to retention, including pretreatment depression, alcohol dependence, legal pressure, and frequency of cocaine use.

Drug abuse treatment retention and process effects on follow-up outcomes.

After finding that retention in methadone treatment for a year or longer was a highly significant predictor of patient outcomes following discharge, measures of pretreatment motivation and early therapeutic engagement were examined as predictors of program retention. Personal interviews were conducted with a sample of 435 patients 12 months after discharge from three methadone treatment programs. Logistic regression results showed several patient attributes--i.e. over 35, lower injection frequency before admission, and higher motivation for treatment--were each associated with twofold increases in the likelihood of having favorable follow-up outcomes on illicit drug use, alcohol use, and criminal involvement. Patients staying in treatment a year or longer, however, were nearly five times more likely to have better outcomes. Further analyses established that length of treatment stay was predicted by higher patient motivation at intake and early program involvement. The findings suggest that more comprehensive models of patient attributes, therapeutic process, and environmental influences are needed, and that treatment enhancement efforts should focus on such during-treatment measures as interim criteria for improving posttreatment outcomes.

Client engagement and change during drug abuse treatment

Previous work has shown length of time in drug abuse treatment is associated with better outcomes, but the role of therapeutic engagement and process needs further examination. In this study, the total number of counseling sessions attended by 557 clients in their first 90 days of community-based outpatient treatment was examined in relation to indicators of treatment delivery and progress. Significant client improvements were found on behavioral criteria and psychosocial functioning during the first 3 months of treatment, and session attendance was positively related to favorable behavioral changes as well as to positive perceptions by clients and counselors of their therapeutic interactions. Client background, treatment motivation, and therapeutic focus of counseling in Month 1 were significant predictors of session attendance in the first 3 months following admission to methadone treatment.

Measuring patient attributes and engagement in treatment

Brief but comprehensive instruments measuring patient motivation, psychosocial functioning, treatment process, social network support, and services received are needed for monitoring drug abuse treatment delivery and patient progress. Combining this information across patients within a program also provides useful indicators about institutional composition and functioning. Consequently, the same assessment tools can be used to identify areas where treatment protocols need to be changed, and to monitor improvements following such changes. The Texas Christian University (TCU) Client Evaluation of Self and Treatment (CEST)(1) is a 144-item self-rating instrument that includes 16 scales measuring patient functioning and treatment perceptions. Psychometric properties (including reliability and construct validity) of the scales are examined in this article, based on patient samples drawn from 87 programs that participated in a series of staff training workshops. Acceptable reliabilities (.70 or above) were generally reported, and construct validity was also demonstrated (although the confirmatory factor analyses suggested some item pools could represent more than one factor). Prediction analyses were conducted using selected scales from each measurement domain to illustrate their sensitivity to treatment program contexts.

Gender differences at admission and follow-up in a sample of methadone maintenance clients

Although one-third of clients enrolled in methadone treatment in the United States are female, few studies have looked at gender differences at admission and follow-up. Using interview data from 435 clients (31% female) collected at admission and approximately 1 year after discharge, females were found to have more dysfunctional families of origin and greater prior and current psychological and medical problems. Both genders improved following treatment, as evidenced by reduced illicit drug, tobacco, and alcohol use, criminal involvement, and HIV/AIDS-risky behaviors. Females were more likely to seek further help for both drug misuse and psychological problems subsequent to discharge.

Treatment predictors of tenure in methadone maintenance

Tenure in methadone maintenance treatment was analyzed in terms of treatment process factors using a survival curve regression analysis. The treatment process framework included client variables at entry, program characteristics, treatment events, and client attitudes and satisfaction. The sample consisted of 606 methadone maintenance clients from 21 different clinics. Significant predictors included professional classifications of the diagnosing and treatment-planning staff members, measures of early treatment services, client attitudes and satisfaction, methadone dosage level, and frequency of urine monitoring. The results showed higher tenure rates when specialized professionals diagnosed problems and defined treatment plans, when service needs were addressed, when client attitudes and satisfaction were high, and when methadone dose was higher. Lower tenure rates were found among blacks and clients with lower sociodemographic status. Lower tenure also occurred among those who perceived the program as less accessible or less structured in its procedures.

Patient and program attributes related to treatment process indicators in DATOS

Patient ratings of their personal confidence in treatment and commitment to recovery were examined in a national sample of long-term residential, outpatient drug-free, and outpatient methadone programs. It was found that patients expressing greater confidence and commitment after 3 months of treatment generally began with higher motivation at intake, had formed better rapport with counselors, and attended counseling sessions more frequently. In addition, overall levels of patient involvement (as indicated by confidence and commitment) varied across programs; those programs with higher average involvement by patients used more social and public health services, maintained more consistent attendance at counseling sessions, and served patients who collectively had more similar kinds of needs. Thus, patient and program attributes both play a role in determining therapeutic engagement of persons who enter drug treatment.

Recovery from opioid addiction in DATOS

Patient attributions for their own long-term recovery were obtained in a 5-year followup of 432 admissions to 18 outpatient methadone treatment programs. Subjects were classified into two groups - recovering and non-recovering-strictly defined and based on both biological and self-report measures of no opioid or cocaine use, less than daily use of alcohol, and no arrests or illegal activity during the year prior to interview. The 28% who were in recovery at Year 5 reported that they had relied primarily upon personal motivation, treatment experiences, religion/spirituality, family, and their job/career. Particular value was placed on the support from family and close friends, indicating the importance of stronger efforts to develop social networks for support of drug-free functioning, especially among patients who lack these resources or need them strengthened.

Addiction Careers: Etiology, Treatment, and 12-Year Follow-up Outcomes

Follow-up interviews were conducted with 405 black and white male opioid addicts 12 years after admission to drug abuse treatments in the Drug Abuse Reporting Program. Outcomes over time in this longitudinal data system showed that the behavioral improvements observed throughout the first 6-year posttreatment follow-up period (compared with pretreatment baselines) tended to stabilize between Years 6 and 12. About one-fourth of the sample still used opioid drugs daily in Year 12. Demographic and background measures generally failed to predict Year 12 outcomes, although Year 6 outcomes were related to those in Year 12. Reasons for starting, continuing, and terminating opioid addiction were also examined, as well as the importance of treatment during addiction careers.
