Developing adaptive treatment strategies in substance abuse research.

For many individuals, substance abuse possesses characteristics of chronic disorders in that individuals experience repeated cycles of cessation and relapse; hence viewing drug dependence as a chronic, relapsing disorder is increasingly accepted. The development of a treatment for a chronic disorder requires consideration of the ordering of treatments, the timing of changes in treatment, and the use of measures of response, burden and adherence collected during treatment to make further treatment decisions. Adaptive treatment strategies provide a vehicle through which these issues can be addressed and thus provide a means toward improving and informing the clinical management of chronic substance abuse disorders. The sequential multiple assignment randomized trial (SMART) is particularly useful in developing adaptive treatment strategies. Simple analyses that can be used with the SMART design are described. Furthermore, the SMART design is compared with standard experimental designs.

Counselor incentives to improve client retention in an outpatient substance abuse aftercare program.

Pay for performance, the provision of financial incentives for favorable performance, is increasingly under study as an evidence-based practice. This study estimated the improvement in client retention from offering incentives to 11 substance abuse counselors providing outpatient aftercare treatment. During the incentive period, a counselor could earn a bonus of $100, in addition to his regular compensation, for each client who completed at least five aftercare sessions (the "milestone" which we considered the minimum adequate dose of the aftercare curriculum). We evaluated this and a similar, 12-session incentive using a logistic regression in which the retention "milestone" was the dependent variable and the proportion of time in the incentive condition was the independent variable. Among the 123 clients offered this aftercare program, their probability of completing at least 5 sessions was 59% with the incentive compared to 33% beforehand (odds ratio 4.1, P<.01). These findings suggest that counselor incentives are an effective strategy to improve client retention in substance abuse treatment.

Continuing care in the treatment of addictive disorders.

Newer models of continuing care in the addictions are designed to improve the long-term management of substance use disorders by engaging patients into flexible, or "adaptive," treatment algorithms that change in focus and intensity as symptoms wax and wane over time. This article describes some of these newer approaches to the management of substance use disorders and presents recent research on their effectiveness. Findings suggest the following: 1) Continuing care interventions of a year or longer are more likely to show significant positive effects; 2) Continuing care treatments that are less burdensome to patients appear to promote higher rates of sustained engagement; 3) More structured and intensive continuing care may be more effective for patients with severe substance dependence and associated problems and for those who fail to achieve reasonable progress while in the initial phase of treatment; and 4) Use of medications as part of continuing care is increasing.

Long-term posttreatment functioning among those treated for alcohol use disorders.

This article summarizes the proceedings of a symposium that was organized and chaired by Patrick R. Clifford and presented at the 2005 Research Society on Alcoholism meeting in Santa Barbara, California. The aims of the presentation were to focus on the prediction and explanation of longer-term functioning following alcohol use disorders (AUD) treatment. Along these lines, Stephen A. Maisto, PhD, presented data (i.e., Project MATCH outpatient sample) on the relationship between drinking behavior in the first year following AUD outpatient treatment initiation and functioning at 3-year follow-up. Robert L. Stout, PhD, using data from the Extended Case Monitoring Study, analyzed long-term drinking patterns using shorter-term information. James R. McKay, PhD, examined the relationship between treatment services received and problem severities across a 2-year follow-up period. J. Scott Tonigan, PhD, served as the panel discussant.

Conceptual, methodological, and analytical issues in the study of relapse.

This article examines conceptual, methodological, and analytic issues in research on relapse to alcohol and other drug use. The review notes the continued move in relapse research from a primary reliance on retrospective assessment of factors surrounding the onset of relapse episodes to an increased focus on the use of new technologies to obtain "near real time" data on proximal factors in relapses. Recent advances in neurobiology have yielded important gains in our understanding of vulnerability to relapse in alcohol and other drug abusers. New statistical techniques are also available to analyze data on relapse. From a theoretical standpoint, there has been an increasing appreciation for the complicated and dynamic interplay of distal and proximal factors in the relapse process. At this point, the strongest and most detailed data on factors in the onset and course of relapse have been generated by studies of smoking relapses that have made use of Ecological Momentary Assessment (EMA) technology. However, there is still limited "near real" time data on proximal factors in alcohol and other drug relapses, and no such data on factors that influence the course of these relapses, once they have begun. Nevertheless, important methodological advances have been and continue to be made in the study of relapse, and our knowledge about the nature and process of relapse has increased considerably over the past 10 years.

The effectiveness of telephone-based continuing care for alcohol and cocaine dependence: 24-month outcomes.

CONTEXT: Telephone-based disease management protocols have shown promise in improving outcomes in a number of medical and psychiatric disorders, but this approach to continuing care has received little study in alcohol- and drug-dependent individuals. OBJECTIVE: To compare telephone-based continuing care with 2 more intensive face-to-face continuing care interventions. DESIGN: A randomized 3-group clinical trial with a 2-year follow-up. SETTING: Two outpatient substance abuse treatment programs, one community-based and the other at a Veterans Affairs medical center facility. PATIENTS: Alcohol- and/or cocaine-dependent patients (N = 359) who had completed 4-week intensive outpatient programs. INTERVENTIONS: Three 12-week continuing care treatments: weekly telephone-based monitoring and brief counseling contacts combined with weekly supportive group sessions in the first 4 weeks (TEL), twice-weekly cognitive-behavioral relapse prevention (RP), and twice-weekly standard group counseling (STND). MAIN OUTCOME MEASURES: Percentage of days abstinent from alcohol and cocaine, total abstinence from alcohol and cocaine, negative consequences of substance use, cocaine urine toxicological results, and gamma-glutamyltransferase. RESULTS: Participants in TEL had higher rates of total abstinence over the follow-up than those in STND (P<.05). In alcohol-dependent participants, 24-month gamma-glutamyltransferase levels were lower in TEL than in RP (P = .005). In cocaine-dependent participants, there was a significant group x time interaction (P = .03) in which the rate of cocaine-positive urine samples increased more rapidly in RP as compared with TEL. On percentage of days abstinent or negative consequences of substance use, TEL did not differ from RP or STND. Participants with high scores on a composite risk indicator, based on co-occurring alcohol and cocaine dependence and poor progress toward achieving intensive outpatient program goals, had better total abstinence outcomes up to 21 months if they received STND rather than TEL, whereas those with lower scores had higher abstinence rates in TEL than in STND (P = .04). CONCLUSIONS: Telephone-based continuing care appears to be an effective form of step-down treatment for most patients with alcohol and cocaine dependence who complete an initial stabilization treatment, compared with more intensive face-to-face interventions. However, high-risk patients may have better outcomes if they first receive group counseling continuing care after completing intensive outpatient programs.

Predictors of alcohol and crack cocaine use outcomes over a 3-year follow-up in treatment seekers.

This study identified predictors of long-term alcohol and crack cocaine use outcomes in individuals participating in the Persistent Effects of Treatment Study. The domains that were assessed included motivation, self-efficacy, social support, psychiatric severity, employment, housing status, and self-help group attendance at baseline and 6, 12, 24, and 30 month follow-ups. In alcohol users, higher perceived seriousness of substance use problems, self-efficacy, and self-help group attendance, as well as lower social support for substance use, consistently predicted better alcohol use outcomes in the subsequent assessment period. In crack cocaine users, only self-efficacy consistently predicted cocaine use outcomes. Higher self-efficacy during follow-up was predicted by lower perceived seriousness of substance use and lower alcohol use frequency in the prior assessment period, whereas greater self-help group attendance was predicted by greater perceived seriousness of substance use, and lower substance use frequency.

Do patient characteristics and initial progress in treatment moderate the effectiveness of telephone-based continuing care for substance use disorders?

AIMS: To determine whether substance use severity, psychiatric severity, social support, self-help attendance or motivation moderated substance use outcomes in a telephone-based continuing care intervention. DESIGN: A randomized study comparing three 12-week continuing care interventions: weekly telephone monitoring and counseling combined with a support group in the first 4 weeks (TEL), twice-weekly individualized relapse prevention (RP) and twice-weekly standard group counseling (STND). METHODS: Following completion of 4-week intensive out-patient programs (IOP), 359 patients with alcohol and/or cocaine dependence were assigned randomly to a continuing care condition and followed quarterly for 12 months. Ten potential moderator variables were examined in separate analyses. Two of these variables reflected pretreatment status, whereas the other variables were focused on performance while in the IOP. A composite risk measure was also constructed from dichotomized versions of seven of these variables, with higher scores indicating greater potential for relapse. The dependent measures were total abstinence and percentage of days abstinent from alcohol and cocaine in each quarter. FINDINGS: Of 40 interaction contrasts that were examined with individual risk indicator measures, only one reached the 0.05 level of significance. Patients with any alcohol use in IOP had a higher percentage of days abstinence in STND than in TEL. In addition, high scores on the composite risk indicator predicted higher total abstinence rates in STND than in TEL, whereas low to moderate scores predicted higher abstinence rates in TEL than in STND. CONCLUSION: For most graduates of IOPs, the combination of brief weekly telephone therapeutic contacts and a support group in the first month produced outcomes that are as good as those obtained in more intensive face-to-face continuing care interventions. However, patients with current dependence on both alcohol and cocaine who make little progress towards achieving the central goals of IOP may have better outcomes if they receive twice-weekly group counseling following IOP.

Reconsidering the evaluation of addiction treatment: from retrospective follow-up to concurrent recovery monitoring.

Historically, addiction treatments have been delivered and evaluated under an acute-care format. Fixed amounts or durations of treatment have been provided and their effects evaluated 6-12 months after completion of care. The explicit expectation of treatment has been enduring reductions in substance use, improved personal health and social function, generally referred to as 'recovery'. In contrast, treatments for chronic illnesses such as diabetes, hypertension and asthma have been provided for indeterminate periods and their effects evaluated during the course of those treatments. Here the expectations are for most of the same results, but only during the course of continuing care and monitoring. The many similarities between addiction and mainstream chronic illnesses stand in contrast to the differences in the ways addiction is conceptualized, treated and evaluated. This paper builds upon established methods of during-treatment evaluation developed for the treatment of other chronic illnesses and suggests a parallel evaluation system for out-patient, continuing-care forms of addiction treatment. The suggested system retains traditional patient-level, behavioral outcome measures of recovery, but suggests that these outcomes should be collected and reported immediately and regularly by clinicians at the beginning of addiction treatment sessions, as a way of evaluating recovery progress and making decisions about continuing care. We refer to this paradigm as 'concurrent recovery monitoring' and discuss its potential for producing more timely, efficient, clinically relevant and accountable evaluations.

Is there a case for extended interventions for alcohol and drug use disorders?

AIMS: To determine whether there is evidence to support the implementation of extended interventions (i.e. longer than 6 months) for individuals with alcohol or other drug use disorders. METHODS: Literature on extended behavioral and pharmacotherapy interventions was reviewed, along with findings from studies of extended monitoring and monitoring paired with adjunctive counseling. Studies were identified through database searches, citations in prior reviews and examinations of recent volumes of relevant journals. Key terms were defined, and a theoretical rationale was presented for extended treatment. Several adaptive treatment studies that made use of stepped care or continuation protocols were also described. MEASUREMENTS: The primary outcomes that were considered were alcohol and drug use during the intervention and post-intervention follow-ups. Other outcomes were examined when they were included in the articles reviewed. FINDINGS: Most of the studies in the review provided support for the effectiveness of extended interventions for alcohol and drug abusers, whether the extended care was delivered through face-to-face contact or via the telephone. These findings held across all types of interventions that were examined (e.g. behavioral treatment, pharmacotherapy and monitoring). However, only a few studies directly compared extended and standard length version of the same intervention. New developments in addiction treatment with implications for extended care models were also described and discussed. CONCLUSIONS: The findings of the review indicate that maintaining therapeutic contact for extended periods of time with individuals with alcohol and other drug disorders appears to promote better long-term outcomes than 'treatment as usual', although more studies are needed that compare extended and standard versions of interventions. Achieving good compliance and successful disease management with extended interventions will probably require adaptive protocols in which the intensity of treatment can be adjusted up or down in response to changes in symptoms and functioning over time. Future directions in research on extended interventions were discussed.

The effectiveness of telephone-based continuing care in the clinical management of alcohol and cocaine use disorders: 12-month outcomes.

This study of continuing care for substance dependent patients compared a telephone-based monitoring and brief counseling intervention (TEL) with 2 face-to-face interventions, relapse prevention (RP) and standard 12-step group counseling (STND). The participants were graduates of intensive outpatient programs who had current dependence on alcohol and/or cocaine. Self-report, collateral, and biological measures of alcohol and cocaine use were obtained over a 12-month follow-up. The treatment groups did not differ on abstinence-related outcomes in the complete sample (N = 359) or on cocaine use outcomes in participants with cocaine dependence (n = 268). However, in participants with alcohol dependence only (n = 91), TEL produced better alcohol use outcomes than STND on all measures examined and better outcomes than RP on some of the measures.

Treatment services received in the CASAWORKS for Families program.

This article presents information on treatment services received by women participating in an initial multistate evaluation of CASAWORKS families. Results indicated most women received services to address medical, employment, basic needs, alcohol and drug, family, and psychiatric problems during the first six months of the program. The clients also had frequent contact with their case managers and were retained in the program for an average of 222 days. Considerable variation was observed across sites in the percentage of clients who received various services and the number of sessions they received. In Cox regressions, shorter retention in the program was predicted by referral to program from Child Protective Services or parole/probation, social conflicts, employment, and marijuana use at baseline, whereas a history of suicide attempts was associated with longer retention. Longer retention was associated with better alcohol use outcomes but was unrelated to employment or drug use outcomes.

One-year outcomes from the CASAWORKS for Families intervention for substance-abusing women on welfare.

AIM: To evaluate the effectiveness of a multiservice intervention designed to move substance-abusing women on welfare to sobriety and self-sufficiency by addressing their substance abuse, domestic violence, employment, and basic needs. DESIGN: A field evaluation with repeated measures at 6 and 12 months on an intent-to-treat sample of 529 women conducted in 11 selected sites across the country. There were significant improvements shown in substance use and family and social functioning by the 6-month point, and additional improvements in employment by the 12-month point. By 12 months, more than 46% were abstinent from alcohol and other drugs, and 30% were employed at least part-time. There were only modest improvements shown in the medical and psychiatric status of these women. These preliminary findings suggest that site-level interagency coordination and program-level case management were associated with improvements in the targeted areas as predicted by the model. Future work will require a more closely specified, manual-guided form of the intervention plus the inclusion of control groups and cost measures to fully evaluate the cost benefits from the final form of the intervention.

Evaluation of full vs. partial continuum of care in the treatment of publicly funded substance abusers in Washington State.

This study evaluated the relative effectiveness of two forms of publicly funded substance abuse treatment provided in Washington State: The full continuum (FC), in which clients receive approximately three weeks of inpatient treatment prior to outpatient care, and the partial continuum (PC), in which clients are admitted directly to outpatient treatment. Data on treatment process/proximal outcomes, such as psychological distress and readiness to change, were assessed at 8 weeks post intake, and data on treatment services received were obtained at 2, 4, 8, and 12 weeks. Multidimensional outcomes, including alcohol and drug use as well as a number of psychosocial functioning outcomes, were assessed at 3 and 9 months post intake. Results indicated that clients in the FC had greater alcohol, drug, and legal problem severity at intake than those in the PC, whereas medical and employment problem severity was greater in the PC. Clients in the FC received more treatment services in the first 2 weeks than those in the PC, but there were no differences at subsequent points. Outcome analyses at 3 and 9 months indicated that clients in the FC had greater improvements in alcohol, drug, and psychiatric severity than those in the PC. Matching analyses indicated that clients with greater substance-use severity at baseline improved to a greater degree in the FC as compared to the PC. Matching effects were not obtained with medical or psychiatric severity, or readiness to change.

Relation of depression diagnoses to 2-year outcomes in cocaine-dependent patients in a randomized continuing care study.

This study examined the relation between depression diagnoses and outcomes in 132 cocaine-dependent patients who were randomized to relapse prevention (RP) or standard 12-step focused group continuing care and followed for 2 years. Depressed patients attended more treatment sessions and had more cocaine-free urines during treatment than participants without depression, but they drank alcohol more frequently before treatment and during the 18-month posttreatment follow-up. Cocaine outcomes in depressed patients deteriorated to a greater degree after treatment than did cocaine outcomes in patients without depression, particularly in patients in RP who had a current depressive disorder at baseline. The best alcohol outcomes were obtained in nondepressed patients who received RP. The results suggest that extended continuing care treatment may be warranted for cocaine-dependent patients with co-occurring depressive disorders.
