Social reinforcement of substance abuse treatment aftercare participation: Impact on outcome

Social odor choice buffers drug craving

Social interactions are rewarding and protective against substance use disorders, but it is unclear which specific aspect of the complex sensory social experience drives these effects. Here, we investigated the role of olfactory sensory experience on social interaction, social preference over cocaine, and cocaine craving in rats. First, we conducted bulbectomy on both male and female rats to evaluate the necessity of olfactory system experience on the acquisition and maintenance of volitional social interaction. Next, we assessed the effect of bulbectomy on rats given a choice between social interaction and cocaine. Finally, we evaluated the influence of olfactory sensory experience by training rats on volitional partner-associated odors, assessing their preference for partner odors over cocaine to achieve voluntary abstinence and assessing its effect on the incubation of cocaine craving. Bulbectomy impaired operant social interaction without affecting food and cocaine self-administration. Rats with intact olfactory systems preferred social interaction over cocaine, while rats with impaired olfactory sense showed a preference for cocaine. Providing access to a partner odor in a choice procedure led to cocaine abstinence, preventing incubation of cocaine craving, in contrast to forced abstinence or non-contingent exposure to cocaine and partner odors. Our data suggests the olfactory sensory experience is necessary and sufficient for volitional social reward. Furthermore, the active preference for partner odors over cocaine buffers drug craving. Based on these findings, translational research should explore the use of social sensory-based treatments utilizing odor-focused foundations for individuals with substance use disorders.

A Systematic Review of Treatment Maintenance Strategies in Token Economies: Implications for Contingency Management

Contingency management (CM) interventions are based on operant principles and are effective in promoting health behaviors. Despite their success, a common criticism of CM is that its effects to not persist after the intervention is withdrawn. Many CM studies evaluate posttreatment effects, but few investigate procedures for promoting maintenance. Token economy interventions and CM interventions are procedurally and conceptually similar. The token economy literature includes many studies in which procedures for promoting postintervention maintenance are evaluated. A systematic literature review was conducted to synthesize the literature on treatment maintenance in token economies. Search procedures yielded 697 articles, and application of inclusion/exclusion criteria resulted in 37 articles for review. The most successful strategy is to combine procedures. In most cases, thinning or fading was combined with programmed transfer of control via social reinforcement or self-management. Social reinforcement and self-monitoring procedures appear to be especially important, and were included in 70% of studies involving combined approaches. Thus, our primary recommendation is to incorporate multiple maintenance strategies, at least one of which should facilitate transfer of control of the target behavior to other reinforcers. In addition, graded removal of the intervention, which has also been evaluated to a limited extent in CM, is a reasonable candidate for further development and evaluation. Direct comparisons of maintenance procedures are lacking, and should be considered a research priority in both domains. Researchers and clinicians interested in either type of intervention will likely benefit from ongoing attention to developments in both areas.

A comparison of cognitive behavioral therapy for insomnia to standard of care in an outpatient substance use disorder clinic embedded within a therapeutic community: a RE-AIM framework evaluation

Background

Rates of substance use disorders (SUDs) continue to rise in the USA with parallel rises in admissions to outpatient SUD treatment programs. Insomnia symptoms reduce treatment adherence, trigger relapse, and generally undermine SUD recovery efforts. Cognitive-behavioral therapy for insomnia (CBT-I) is the first-line treatment recommended for chronic insomnia. No study has examined the effectiveness of CBT-I for individuals who recently entered an outpatient SUD treatment program embedded within a therapeutic community (i.e., long-term drug-free residential setting).

Methods

A randomized controlled trial conducted at a SUD program embedded in a therapeutic community aimed to compare group-based CBT-I (gCBT-I) (N = 10) with the standard of care (SOC) (N = 11) among individuals who have SUDs and comorbid insomnia. We present a RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework evaluation to provide empirical data on gCBT-I feasibility and facilitators and barriers of conducting an insomnia-focused clinical effectiveness study within a therapeutic community.

Results

Participants in both study arms reported moderately severe insomnia symptoms at admission and reductions in insomnia symptoms over time. Among participants who completed the Insomnia Severity Index (ISI) beyond admission, ISI decreased to ≤ 8 (the clinical cutoff for mild insomnia) in 80% of individuals in the gCBT-I group compared with 25% of individuals in the SOC group. A RE-AIM framework evaluation showed initial success with Reach and Adoption while Implementation, and Maintenance were limited. Effectiveness was inconclusive because of challenges with recruitment, intervention integrity, and missing data that precluded meeting the planned recruitment and study aims and led to study termination. Coordination and communication with staff and leadership facilitated gCBT-I implementation, yet well-known CBT-I barriers including time- and resource-intensive sleep medicine training for interventionalists and maintenance of treatment integrity during an 8-week intervention limited gCBT-I sustainability.

Conclusions

This analysis supports the feasibility of conducting behavioral sleep medicine research in outpatient SUD treatment programs embedded within therapeutic communities. Implementation of an insomnia-focused intervention was widely accepted by patients and providers and has potential to address insomnia symptoms in early SUD recovery. Addressing patient- and organizational-level implementation barriers may enhance the sustainability and scalability of sleep interventions and provide new hope to effectively treat insomnia among people living with SUDs.

The protective effect of operant social reward on cocaine self-administration, choice, and relapse is dependent on delay and effort for the social reward

Social reinforcement-based treatments are effective for many, but not all, people with addictions to drugs. We recently developed an operant rat model that mimics features of one such treatment, the community-reinforcement approach. In this model, rats uniformly choose social interaction over methamphetamine or heroin. Abstinence induced by social preference protects against the incubation of drug-seeking that would emerge during forced abstinence. Here, we determined whether these findings generalize to cocaine and whether delaying or increasing effort for social interaction could reveal possibly human-relevant individual differences in responsiveness. We trained male and female rats for social self-administration (6 days) and then for cocaine self-administration, initially for 2-h/day for 4 days, and then for 12-h/day continuously or intermittently for 8 days. We assessed relapse to cocaine seeking after 1 and 15 days. Between tests, the rats underwent either forced abstinence or social-choice-induced abstinence. After establishing stable social preference, we manipulated the delay for both rewards or for social reward alone, or the response requirements (effort) for social reward. Independent of cocaine-access conditions and sex, operant social interaction inhibited cocaine self-administration and prevented incubation of cocaine seeking. Preference for social access was decreased by the delay of both rewards or social reward alone, or by increased response requirements for social reward, with notable individual variability. This choice procedure can identify mechanisms of individual differences in an animal model of cocaine use and could thereby help screen medications for people who are relatively unresponsive to treatments based on rewarding social interaction.

Impact of Continuing Care on Recovery From Substance Use Disorder

Continuing care is widely believed to be an important component of effective treatment for substance use disorder, particularly for those individuals with greater problem severity. The purpose of this review was to examine the research literature on continuing care for alcohol and drug use disorders, including studies that addressed efficacy, moderators, mechanisms of action, and economic impact. This narrative review first considered findings from prior reviews (published through 2014), followed by a more detailed examination of studies published more recently. The review found that research has generally supported the efficacy of continuing care for both adolescents and adults, but the picture is complex. Reviews find relatively small effects when results from individual studies are combined. However, continuing care of longer duration that includes more active efforts to keep patients engaged may produce more consistently positive results. Moreover, patients at higher risk for relapse may benefit to a greater degree from continuing care. Several newer approaches for the provision of continuing care show promise. These include incentives for abstinence and automated mobile health interventions to augment more conventional counselor-delivered interventions. Primary care can be used to provide medications for opioid and alcohol use disorders over extended periods, although more research is needed to determine the optimal mix of behavioral treatments and other psychosocial services in this setting. Regardless of the intervention selected for use, the status of most patients will change and evolve over time, and interventions need to include provisions to assess patients on a regular basis and to change or adapt treatment when warranted.

An operant social self-administration and choice model in rats

It is difficult to translate results from animal research on addiction to an understanding of the behavior of human drug users. Despite decades of basic research on neurobiological mechanisms of drug addiction, treatment options remain largely unchanged. A potential reason for this is that mechanistic studies using rodent models do not incorporate a critical facet of human addiction: volitional choices between drug use and non-drug social rewards (e.g., employment and family). Recently, we developed an operant model in which rats press a lever for rewarding social interaction with a peer and then choose between an addictive drug (heroin or methamphetamine) and social interaction. Using this model, we showed that rewarding social interaction suppresses drug self-administration, relapse to drug seeking, and brain responses to drug-associated cues. Here, we describe a protocol for operant social interaction using a discrete-trial choice between drugs and social interaction that causes voluntary abstinence from the drug and tests for incubation of drug craving (the time-dependent increase in drug seeking during abstinence). This protocol is flexible but generally requires 8-9 weeks for completion. We also provide a detailed description of the technical requirements and procedures for building the social self-administration and choice apparatus. Our protocol provides a reliable way to study the role of operant social reward in addiction and addiction vulnerability in the context of choices. We propose that this protocol can be used to study brain mechanisms of operant social reward and potentially impairments in social reward in animal models of psychiatric disorders and pain.

Volitional social interaction prevents drug addiction in rat models

Addiction treatment has not been appreciably improved by neuroscientific research. One problem is that mechanistic studies using rodent models do not incorporate volitional social factors, which play a critical role in human addiction. Here, using rats, we introduce an operant model of choice between drugs and social interaction. Independent of sex, drug class, drug dose, training conditions, abstinence duration, social housing, or addiction score in Diagnostic & Statistical Manual IV-based and intermittent access models, operant social reward prevented drug self-administration. This protection was lessened by delay or punishment of the social reward but neither measure was correlated with the addiction score. Social-choice-induced abstinence also prevented incubation of methamphetamine craving. This protective effect was associated with activation of central amygdala PKCδ-expressing inhibitory neurons and inhibition of anterior insular cortex activity. These findings highlight the need for incorporating social factors into neuroscience-based addiction research and support the wider implantation of socially based addiction treatments.

Study protocol: a hybrid effectiveness-implementation trial of Moral Reconation Therapy in the US Veterans Health Administration

Background

Moral Reconation Therapy (MRT) is a cognitive-behavioral intervention aimed at reducing risk for criminal recidivism by restructuring antisocial attitudes and cognitions (i.e., “criminogenic thinking”). MRT has empirical support for reducing risk for criminal recidivism among civilian offenders. Recently, a version of MRT was developed for military veterans; however, no randomized controlled trials (RCT) have been conducted with the veteran-specific protocol, and the effectiveness and implementation potential of MRT outside of correctional settings has not been established.

Methods

Using a Hybrid Type 1 RCT design, this study will test the effectiveness of MRT to reduce risk for criminal recidivism and improve health-related outcomes among justice-involved veterans entering mental health residential treatment at three US Veterans Health Administration (VHA) Medical Centers. Upon admission to the treatment program, justice-involved veterans will complete a baseline assessment, be randomized to usual care (UC) or UC + MRT, and be followed 6 and 12 months post-baseline. A process evaluation will also be conducted to identify barriers and facilitators to implementation of MRT in residential treatment.

Discussion

The primary aim of this study is to evaluate the effectiveness of MRT with justice-involved veterans. If MRT proves effective in this trial, the findings can provide large healthcare systems that serve veterans with an evidence-based intervention for addressing criminogenic thinking among justice-involved adults, as well as guidance on how to facilitate future implementation of MRT in non-correctional settings.

Trial registration

This trial is funded by the VA Health Services Research & Development Program (IIR 14–081) and is registered with ClinicalTrials.gov (ID: NCT02524171).

Importance of short-term continuing care plan adherence on long-term outcomes among patients discharged from residential substance use treatment

BACKGROUND

Patients adherent to their recommended treatment regimen demonstrate favorable outcomes. However, it is unclear whether there are specific short-term continuing care performance variables indicative of better long-term prognosis.

OBJECTIVE

This study determined the impact of attendance at an outpatient appointment within 7 days post-discharge from residential treatment on 12-month outcomes.

METHOD

Data were abstracted from electronic medical records for 275 patients (58.9% male) discharged from a single residential treatment program. All discharge plans included a 7-day outpatient appointment with a provider in their home community. Patients were dichotomized based on their attendance at the initial appointment to yield a re-engagement variable. Twelve-month outcomes included past 30-day and continuous abstinence rates, quality of life, and long-term adherence to continuing care plans.

RESULTS

Patients attending their initial outpatient appointment within 7 days of discharge evidenced better long-term outcomes relative to patients who did not with respect to continuous abstinence (75.4% vs. 37.3%), past-30-day abstinence (92.0% vs. 70.6%), quality of life (94.2% vs. 78.4%), and adherence (66.4% vs. 9.8%). Re-engagement remained a significant predictor of continuous abstinence and quality of life at 12 months after controlling for 12-month adherence and relevant demographic characteristics.

CONCLUSION

Treatment providers are encouraged to emphasize the relative importance of attending initial post-discharge appointments in achieving successful long-term outcomes. Allocation of resources to enhance engagement during residential treatment may be justified in that there may be value in actively encouraging patients to participate in continuing care activities, particularly shortly following discharge.

A conceptual model to facilitate transitions from primary care to specialty substance use disorder care: a review of the literature

AIM

This article presents a conceptual model to help facilitate the transition from primary care to specialty substance use disorder (SUD) care for appropriate patients.

BACKGROUND

Substance misuse is a common health condition among patients presenting to primary care settings and may complicate the treatment of chronic health conditions such as diabetes and hypertension. It is therefore critical that primary care providers be prepared to identify and determine appropriate treatment options for patients presenting with substance misuse.

METHODS

We conducted a narrative review that occurred in three stages: literature review of health care transition models, identification of conceptual domains common across care transition models, and identification of SUD-specific model elements. Findings The conceptual model presented describes patient, provider, and system-level facilitators and barriers to the transition process, and includes intervention strategies that can be utilized by primary care clinics to potentially improve the process of transitioning patients from primary care to SUD care. Recognizing that primary care clinics vary in available resources, we present three examples of care practices along an intensity continuum from low (counseling and referral) to moderate (telephone monitoring) to high (intensive case management) resource demands for adoption. We also provide a list of common outcomes clinics might consider when evaluating the impact of care transition practices in this patient population; these include process outcomes such as patients' increased knowledge of available treatment resources, and health outcomes such as patients' reduced substance use and better quality of life.

The continuing care model of substance use treatment: what works, and when is "enough," "enough?"

There is little disagreement in the substance use treatment literature regarding the conceptualization of substance dependence as a cyclic, chronic condition consisting of alternating episodes of treatment and subsequent relapse. Likewise, substance use treatment efforts are increasingly being contextualized within a similar disease management framework, much like that of other chronic medical conditions (diabetes, hypertension, etc.). As such, substance use treatment has generally been viewed as a process comprised of two phases. Theoretically, the incorporation of some form of lower intensity continuing care services delivered in the context of outpatient treatment after the primary treatment phase (e.g., residential) appears to be a likely requisite if all stakeholders aspire to successful long-term clinical outcomes. Thus, the overarching objective of any continuing care model should be to sustain treatment gains attained in the primary phase in an effort to ultimately prevent relapse. Given the extant treatment literature clearly supports the contention that treatment is superior to no treatment, and longer lengths of stay is associated with a variety of positive outcomes, the more prudent question appears to be not whether treatment works, but rather what are the specific programmatic elements (e.g., duration, intensity) that comprise an adequate continuing care model. Generally speaking, it appears that the duration of continuing care should extend for a minimum of 3 to 6 months. However, continuing care over a protracted period of up to 12 months appears to be essential if a reasonable expectation of robust recovery is desired. Limitations of prior work and implications for routine clinical practice are also discussed.

Remission from alcohol and other drug problem use in public and private treatment samples over seven years

BACKGROUND

The treatment of alcohol and other drugs is now more commonly framed in terms of a chronic condition which requires ongoing monitoring. A model which includes continuing access to health care may optimize outcomes. Most studies of chronic care models have not included health care and have only examined short term effects.

METHODS

The sample (n = 783) included consecutive admissions in ten public and private alcohol and other drug (AOD) treatment programs followed over seven years. The outcome was remission which was defined as alcohol and drug abstinence or non-problem use.

RESULTS

In the private sample, receiving health care services predicted remission across the seven years; however this did not occur in the public sample. More patients in the public treatment sample received AOD treatment readmissions each year, while more of those in the private sector received psychiatric and general health visits. Except for drug problem severity, there were no other clinical differences between the samples. There were no differences in the proportions of patients in the two sectors who received the full spectrum of chronic care services. In the final models, 12-step participation was markedly significant for both samples.

CONCLUSIONS

Models of chronic care for substance use need to consider differences between private and public treatment and should take into account that individuals may not always have access, or avail themselves of services that may optimize long-term outcomes.

Twelve-month follow-up of aftercare for adolescents with alcohol use disorders

Adolescents with alcohol use disorders (AUDs) previously completed a randomized controlled outpatient aftercare study (Y. Kaminer, J. A. Burleson, & R. H. Burke, 2008) in which they were randomly assigned to in-person, brief telephone, or no-active aftercare. Youth were assessed at end of aftercare and at 3-, 6-, and 12-month follow-up on frequency and quantity of alcohol use. It was predicted that active aftercare (in-person and brief telephone) would be superior to no-active aftercare in reducing alcohol use, as shown in the original study. No subject or therapy group attributes were significant moderators of outcome. Active aftercare in general maintained short-term favorable effects by reducing relapse in youth with AUD and should be considered as part of standard procedures in therapeutic interventions for all alcohol and other substance use. In-person and the brief telephone procedures did not differ in their effectiveness. Structured communications with AUD youth during and after treatment by use of electronic technology rather than in-person contact might therefore be more fully investigated.

Factors associated with frequent utilization of crisis substance use detoxification services

Previous research suggests that some substance users have multiple crisis detoxification visits and never access rehabilitation care. This care-seeking pattern leads to poorer outcomes and higher costs. The authors aimed to identify predictors of repeat detoxification visits by analyzing state-level data routinely collected at the time of substances use services admission. Repeat detoxification clients were more likely to be homeless, city-dwelling fee-for-service Medicaid recipients. Repeat detoxification clients were less likely than those with one admission to enter rehabilitation within 3 days. Treatment providers should aim for rapid transfer to rehabilitation and consider expanding detoxification intake data to improve risk stratification.

Long-Term Outcomes of Aftercare Participation following Various Forms of Drug Abuse Treatment in Scotland

Due to high relapse rates after leaving treatment, drug users are often recommended to participate in some form of lower intensity continuing care. The importance of aftercare is widely accepted, but little empirical data are available about the effectiveness of continuing services over longer periods of time and following various treatment modalities. In this study, we assessed the influence of various forms of aftercare on treatment outcomes and service utilization over a 33-month period among a naturalistic cohort of 653 drug users treated in prison or community settings, as part of the Drug Outcome Research in Scotland (DORIS study). Although participation in aftercare after initial treatment is rather unusual, the odds of having experienced a drug-free period (after 8 months) (OR = 1.91, 95% CI 1.10–3.33) and of being abstinent from heroin (after 33 months) (OR= 0.56, 95% CI 0.34–0.94) almost doubled. Program aftercare was of little additional value after intensive residential treatment, but particularly important after prison-based and community treatment and if combined with self-help participation. Consequently, attractive and fitted aftercare services should be offered as an integrated part of various treatment modalities.

Facilitating outpatient treatment entry following detoxification for injection drug use: a multisite test of three interventions

A multisite, randomized trial within the National Drug Abuse Treatment Clinical Trials Network (CTN) was conducted to test 3 interventions to enhance treatment initiation following detoxification: (a) a single session, therapeutic alliance intervention (TA) added to usual treatment; (b) a 2-session, counseling and education, HIV/HCV risk reduction intervention (C&E), added to usual treatment; and (c) treatment as usual (TAU) only. Injection drug users (n=632) enrolled in residential detoxification at 8 community treatment programs were randomized to 1 of the 3 study conditions. TA participants reported entering outpatient treatment sooner and in greater numbers than TAU participants. Reported treatment entry for C&E fell between TA and TAU with no significant differences between C&E and the other conditions. There were no differences among the interventions in retention, as measured by weeks of outpatient treatment for all participants who reported treatment entry. Alliance building interventions appear to be effective in facilitating transfer from detoxification to outpatient treatment, but additional treatment engagement interventions may be necessary to improve retention.

Continuing care research: what we have learned and where we are going

In the field of addiction treatment, the term continuing care has been used to indicate the stage of treatment that follows an initial episode of more intensive care. This article reviews controlled studies of continuing care conducted over the prior 20 years. The results indicate that continuing care interventions were more likely to produce positive treatment effects when they had a longer planned duration, made more active efforts to deliver treatment to patients, and were studied more recently. However, there was considerable variability in patient response and room for improvements in participation rates and effectiveness. It is possible that the effectiveness of continuing care interventions could be further improved by the use of adaptive algorithms, which adjust treatment over time based on changes in patients' symptoms and status. The use of alternative service delivery methods and care settings may also lead to greater engagement and retention in continuing care, particularly among the large numbers of individuals who do not want traditional, clinic-based specialty care.

Promoting continuing care adherence among substance abusers with co-occurring psychiatric disorders following residential treatment

Epidemiological data from treatment and community samples of individuals with substance use disorders indicate that the rates of co-occurring psychiatric disorders are high and that these disorders are associated with poor treatment adherence and outcomes. A growing body of research indicates that continuing care adherence interventions positively impact treatment outcome. However, it is unclear whether these interventions are effective for individuals with co-occurring psychiatric disorders. This paper explores this question with data from 150 participants who were randomized to receive a behavioral continuing care adherence intervention involving contracting, prompting and reinforcing attendance (CPR), or standard treatment. Fifty-one percent of the participants had one or more co-occurring Axis I or Axis II psychiatric disorders in addition to a SUD diagnosis. Among individuals with co-occurring disorders, those who received the CPR intervention show increased duration of treatment and improved 1-year abstinence rates compared to those who received STX. Additionally, effects of the CPR intervention were generally more pronounced among persons with co-occurring Axis I and/or Axis II disorders than those without these disorders. Treatment implications are discussed.

The efficacy of symbolic modeling and vicarious reinforcement in increasing coping-method adherence

The aim of this study was to test a method of increasing adherence to a coping method assignment in individuals interested in reducing stress. Eighty university students and 48 adult nonstudents were asked to write about their emotions for 15 minutes per day over 3 days. Participants were randomly assigned to experimental or control conditions, with the experimental manipulation being an adherence intervention involving symbolic modeling and vicarious reinforcement. A word count and self-report measures showed significantly higher adherence in the adherence intervention group. Additionally, the adherence intervention group showed significantly more reduction in distress than the writing instructions only group. Finally, the amount of adherence was significantly associated with amount of reduction in self-reported distress. The results provide the first evidence of the efficacy of symbolic modeling and vicarious reinforcement in increasing the use and clinical benefits of a recommended coping method.

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.

Continuity of care practices and substance use disorder patients' engagement in continuing care

BACKGROUND

Substance use disorder (SUD) patients who engage in more continuing care have better outcomes, but information on practices associated with greater patient engagement and retention in continuing care remains elusive.

OBJECTIVES

The objectives of this study were to determine if staff's continuity of care practices predict patients' engagement in continuing care in the 6 months after discharge from intensive SUD treatment and to determine if the impact of continuity of care practices on patients' engagement in continuing care differs for patients treated in inpatient/residential versus outpatient programs.

RESEARCH DESIGN

Staff in 28 Veterans Affairs (VA) intensive SUD treatment programs with varying continuity of care practices provided data on 878 patients' alcohol and drug problems at treatment entry. At discharge, staff provided data on patients' motivation, treatment intensity, and on the continuity of care practices they used with each patient. VA administrative databases supplied data on patients' subsequent engagement in continuing care. Mixed-effects modeling was used to examine predictors of patients' engagement in care.

RESULTS

Patients in outpatient programs who received more continuity of care engaged in continuing care significantly longer. More highly motivated outpatients, those with fewer alcohol problems at treatment entry, and patients who used VA services in the year before treatment also remained in continuing care longer. These findings did not hold for patients treated in inpatient/residential programs.

CONCLUSIONS

Continuity of care practices predicted engagement in continuing care only for patients treated in outpatient SUD programs. More research is needed to identify effective continuity of care practices for patients treated in inpatient/residential programs.

The impact of contracting and prompting substance abuse treatment entry: a pilot trial

Contracting and prompting clients to attend substance abuse treatment aftercare substantially improves treatment adherence and outcome. However, this approach has not been evaluated for improving entry into initial treatment. We recruited 102 individuals scheduled to begin a 28-day substance use disorder (SUD) residential treatment program and randomly assigned them to receive either our standard treatment (STX) or STX plus attendance contracting and prompting (CP). CP participants showed fewer subsequent hospitalization days, lower hospitalization costs, greater improvement in alcohol problem scores, and lower legal problem scores at a 3-month follow-up than the STX group. The two groups did not differ on treatment entry rate, time in treatment, or drug use problem scores. The clinical utility of CP procedures and areas for future research are discussed.
