Role of social support and self-efficacy in treatment outcomes among clients with co-occurring disorders

Individuals with co-occurring substance use and psychiatric disorders have a more severe clinical course and poorer outcomes than do individuals with one disorder. In an attempt to find intervening variables that may contribute to improvement in treatment outcomes among individuals with co-occurring disorders, we investigated the roles of social support and self-efficacy in a sample of 351 clients with co-occurring disorders in residential drug abuse treatment programs (53% male; 35% African American, 13% Hispanic). Given their demographic variability, we also explored how ethnicity and age influence self-efficacy and access to social support, as well as their relationships to the outcomes. Structural equation modeling was used to examine the impact of the demographics and baseline psychological status, substance use, social support, and self-efficacy on mental health and substance use outcomes 6 months after treatment entry. Time in treatment was included as a control. Greater social support at baseline predicted better mental health status and less heroin and cocaine use; greater self-efficacy predicted less alcohol and cocaine use. Older clients reported less social support. African-American ethnicity was associated with more cocaine use at baseline and follow-up; however, African Americans reported more self-efficacy, which moderated their cocaine use. The current study highlights the potential therapeutic importance of clients' personal resources, even among a sample of severely impaired individuals.     

Predictors of Residential Treatment Retention among Individuals with Co-Occurring Substance Abuse and Mental Health Disorders

Abstract

A significant number of individuals with co-occurring substance abuse and mental health disorders do not engage, stay, and/or complete residential treatment. The purpose of this study is to identify factors during the initial phase of treatment which predict retention in private residential treatment for individuals with co-occurring substance use and mental health disorders. The participants were 1,317 individuals with co-occurring substance abuse and mental health disorders receiving treatment at three residential treatment centers located in Memphis, TN, Malibu, CA, and Palm Springs, CA. Bivariate analysis and logistic regression were utilized to identify factors that predict treatment retention at 30 days. The findings indicate a variety of factors including age, gender, types of drug, Addiction Severity Index Medical and Psychiatric scores, and readiness to change. These identified factors could be incorporated into pretreatment assessments, so that programs can initiate preventive measures to decrease attrition and improve treatment outcomes.     

Stability of Outcomes Following Residential Drug Treatment For Patients with Co-occurring Disorders

OBJECTIVE: Few studies have examined the stability of both substance use and mental health outcomes following residential drug abuse treatment for individuals with co-occurring disorders (COD). This study examines outcomes at 6 and 12 months for individuals with COD, in relationship to services received over the follow-up period. METHODS: Participants with COD (N=310) were sampled from 11 residential drug abuse treatment programs and completed in-depth assessments within 30 days of intake and at 6- and 12-month follow-ups. A path model was developed testing the relationships among treatment participation and services received, psychological status, and substance use outcomes across the two follow-up points. RESULTS: Retention for at least 90 days in residential drug treatment was associated with less inpatient mental health treatment and more mental health services received at 6 months; outpatient mental health treatment was associated with reduced substance use at 6 months. Substance use at 6 months was associated with more psychological distress at both 6 and 12 months and more inpatient mental health treatment at 12 months. CONCLUSIONS: Findings suggest that receipt of mental health services following residential drug abuse treatment for patients with COD is critical to improving their longer-term outcomes.     

Psychosocial Interventions for Adults with Severe Mental Illnesses and Co-Occurring Substance Use Disorders

Abstract

A growing body of research supports the effectiveness of integrated treatment for people with co-occurring severe mental illness and substance use disorders (dual disorders), but the effects of specific interventions are less clear. This review focuses on the effects of specific psychosocial interventions for dual disorders, including individual, group, and family modalities, as well as structural (e.g., case management model), procedural (e.g., contingency management), residential, and rehabilitation (e.g., vocational) interventions, with an emphasis on randomized controlled trials. Controlled research on specific individual interventions has focused mainly on motivation enhancement approaches for clients in the earlier stages of treatment, and has reported improved retention in treatment and substance abuse outcomes. Group interventions have been most extensively studied, with findings indicating that a variety of different treatment approaches specifically designed for dual disorder clients (e.g., emphasizing education, motivational enhancement, cognitive-behavioral counseling) are more effective at improving substance abuse outcomes than no group treatment or standard 12-Step approaches. Structural studies suggest that increasing the intensity of integrated dual disorder treatment produces only modest benefits. Residential dual disorder programs show great promise, especially for clients who are homeless and without psychosocial supports. Research on family therapy, procedural interventions, or rehabilitation is too premature at this time to draw any conclusions, although promising results have emerged in each area. Future avenues for research on specific interventions for dual disorders are considered.     

Training substance abuse treatment staff to care for co-occurring disorders

Although co-occurring disorders have been associated with poorer substance abuse treatment outcomes and higher costs of care, few individuals with co-occurring disorders receive appropriate mental health care. This article describes the design and implementation of an intervention to improve the quality of mental health care provided in outpatient substance abuse treatment programs without requiring new treatment staff. The intervention focuses on individuals with affective and anxiety disorders and consists of three components: training and supervising staff, educating and activating clients, and linking with community resources. We evaluated three treatment programs (one intervention and two comparison) for the first component by having program staff complete both self-administered questionnaires and semistructured interviews. Staff knowledge and attitudes about co-occurring disorders, job satisfaction, and morale all indicated an improvement at the intervention relative to the comparison sites. The evaluation is still under way; results for implementation of the other two components and for outcomes will be reported later.     

Recovery challenges among dually diagnosed individuals

Although there is a high prevalence of co-occurring mental and substance abuse disorders, and empirical evidence shows the need to integrate multiple treatment services for dually diagnosed persons, service integration is relatively recent and often poorly implemented. Moreover, service providers and clients often hold divergent views of what constitute appropriate and feasible treatment goals. This paper presents interview data from an urban sample of dually diagnosed members of self-help groups (N = 310) concerning the challenges confronting them in their recovery, and discusses the interrelations of these issues. The findings indicate that most clients struggle with emotional and socioeconomic issues, which bear significantly on their ability to handle adequately other aspects of recovery.     

An Outcome Study of the CASA-CHESS Smartphone Relapse Prevention Tool for Latinx Spanish-Speakers with Substance Use Disorders

Background: Hispanic/Latinx persons with alcohol and other drug disorders (AOD) have limited access to culturally competent continuity of care. To address this, the evidence-based smartphone recovery application Addiction-Comprehensive Health Enhancement Support System (A-CHESS) was translated and adapted for Latinx Spanish-speakers with AOD, developing CASA-CHESS. Objectives: This study examined the AOD and mental health outcomes for Latinx Spanish-speaking clients using the CASA-CHESS smartphone tool over a 6-month period, post-residential treatment. This single group, pre-post study design included seventy-nine male and female Spanish-speaking Latinx clients, equipped with CASA-CHESS as they completed residential AOD treatment. Primary outcome measures at baseline and 6-month follow-up included substance use and other mental health symptoms. Results: While over 70% of the sample reported past heroin use and alcohol use, clients had low baseline rates of substance use, depression and anxiety and elevated social support scores as they graduated from residential treatment. Overall participants maintained their relatively low baseline rates during the 6-month post-residential period while using the CASA-CHESS relapse prevention tool. Those who discontinued using CASA-CHESS within the first 4?months after leaving residential treatment reported higher rates of substance use as well as anxiety and depression symptoms than those using it for 4 or more months, suggesting that continued use of CASA-CHESS may contribute to maintenance of successes gained in treatment. Conclusions/Importance: CASA-CHESS may reduce the risk of relapse for Latinx Spanish-speakers following residential services and extend needed access to culturally and linguistically competent aftercare services for those with AOD.     

Problematic cannabis use amongst those with severe mental health problems in an inner city area of the UK

The prevalence and nature of cannabis use amongst those with severe mental health problems in community-based services in an inner city area of the UK was assessed. A questionnaire completed by keyworkers of clients engaged with statutory services assessed mental health problems, patterns of substance use, and perceived reasons for substance use. One hundred fifty-nine keyworkers gave information on 1369 clients with severe mental health problems. Three hundred twenty-four of these clients were identified as also using substances problematically. Forty-three percent (139/324) of these clients were misusing cannabis. Within mental health services, cannabis, second to alcohol, was the substance most commonly used problematically. Problematic cannabis use was most frequently associated with males and a diagnosis of schizophrenia, schizotypal or delusional disorders. The median age was 30 years. Pleasure enhancement and coping reasons were most commonly cited by keyworkers for their clients' substance use. Problematic cannabis use was common. Due to the fairly unique profile of cannabis and the emphasis/focus of treatment services, it is possible that cannabis use may be too heavily emphasised or too easily ignored by health professionals.     

Use of specialty substance abuse and mental health services in adults with substance use disorders in the community

AIMS: To examine the patterns and correlates of use of specialty substance abuse and mental health services among adults with alcohol or non-alcohol drug abuse or dependence in the community. METHODS: Analyses focused on 5,568 participants with alcohol or non-alcohol drug abuse or dependence drawn from a large representative cross-sectional survey of the US general population-the 2002 US National Survey on Drug Use and Health (NSDUH). RESULTS: Only 9.7% of adults with substance use disorders used specialty substance abuse services in the past year; 22.4% used mental health services. Severity of substance use disorder and less education were associated with using substance abuse services. Whereas psychological distress and impairment in role functioning due to psychological problems were associated with mental health service use. Male gender, black race/ethnicity, and lack of health insurance acted as barriers to using mental health services but not specialty substance abuse services. Past year use of substance abuse services, but not mental health services, was associated with lower likelihood of continued use of substances in the past month. CONCLUSIONS: Individuals with substance use disorders are more likely to use mental health services than specialty substance abuse services. However, only people who use specialty substance abuse services have a lower risk of continued use of substances. Findings highlight the need for integration of substance abuse treatments in the mental health care system and attention to different barriers to the two types of services.     

Prevalence and comorbidity of major internalizing and externalizing problems among adolescents and adults presenting to substance abuse treatment

As the field follows recommendations to introduce standardized assessments on substance, mental, and behavioral problems, a consistent picture has emerged that co-occurring disorders are common, that there is heterogeneity in the type of disorder, and that the pattern varies by age. This study examines the prevalence of self-reported substance use and mental health problems, the pattern of comorbidity, and how both vary by age among people presenting to substance abuse treatment. Data are from 4,930 adolescents and 1,956 adults admitted to substance abuse treatment in multisite studies who were assessed with the Global Appraisal of Individual Needs and categorized into five age groups: <15, 15-17, 18-25, 26-39, and 40+ years. Two thirds of clients had a co-occurring mental health problem in the year prior to treatment admission. Across all ages, clients self-reporting criteria for past-year substance dependence were more likely than those who did not to have other co-occurring mental health problems (odds ratios of 2.9 to 8.8). The prevalence and patterns of co-occurring mental health problems, however, varied by age. Young adults (ages 18-25) were found to be most vulnerable to co-occurring problems.     

Mental health versus substance abuse treatment programs for dually diagnosed patients

The aim of this study was to assess the similarities and differences of patients with co-existing psychiatric and substance use disorders attending treatment in either a mental health setting or a substance abuse treatment setting. A total of 129 patients were assessed, including 65 individuals from the substance abuse treatment center and 64 individuals from the mental health program. Treatment records were reviewed for diagnoses and sociodemographic data. While the two groups were highly similar with regard to age and ethnicity, there were significant differences in psychiatric profile, with the substance abuse treatment group having less severe diagnoses and no patients with schizophrenia, while the mental health treatment group had a majority of patients with schizophrenia. Other differences in the two groups, such as marital and parental status, disability status, and medical problems appeared to be directly linked with the aforementioned diagnostic profile. These data suggest important differences in characteristics of patients with comorbid disorders that appear to be dependent on the type of treatment program they attend. For the most effective management, integrated treatment programs should be aware of these differences and tailor service provision accordingly.     

Why the concept-based therapeutic community can no longer be called drug-free

In the last two decades, a complex controversy has emerged in therapeutic community (TC) drug treatment programs, many of which are experiencing a marked increase in addicted clients with co-existing mental health disorders. This situation calls into question many theoretical and practical aspects of the TC approach to addiction recovery. Among the central issues: use of psychotropic medications for the increasing cases of comorbidity among substance abuse clients entering the TC, the influx of mental health professionals, and employment of a growing number of mental health interventions or services. The traditional drug-free self-help approach to drug treatment by the TC (with its own set of treatment interventions) and its historic dominance by ex-addicts or recovering persons as key staff are undergoing change. Integrating a biopsychosocial model into the traditional TC treatment modality requires a variety of adjustments that challenge the status quo in these programs. In particular, the use of psychotropic medications and mental health service providers in TC programs has improved the delivery of treatment to clients but at the same time it has created a cultural conflict for paraprofessional staff espousing the drug-free self-help philosophy. The clinical implications and organizational challenges of this predicament are described. Recommendations are provided on how to accept current health care realities without compromising the unique qualities of the TC approach.     

Substance abuse treatment and receipt of liver specialty care among persons coinfected with HIV/HCV who have alcohol problems

We examined the association of substance abuse treatment with access to liver specialty care among 231 persons coinfected with HIV and hepatitis C virus (HCV) with a history of alcohol problems who were recruited and followed up in the HIV-Longitudinal Interrelationships of Viruses and Ethanol cohort study from 2001 to 2004. Variables regarding demographics, substance use, health service use, clinical variables, and substance abuse treatment were from a standardized research questionnaire administered biannually. We defined substance abuse treatment services as any of the following in the previous 6 months: 12 weeks in a halfway house or residential facility, 12 visits to a substance abuse counselor or mental health professional, day treatment for at least 30 days, or any participation in a methadone maintenance program. Liver specialty care was defined as a visit to a liver doctor, a hepatologist, or a specialist in treating hepatitis C in the past 6 months. At study entry, most of the 231 subjects (89%, n = 205) had seen a primary care physician, 50% had been exposed to substance abuse treatment, and 50 subjects (22%) had received liver specialty care. An additional 33 subjects (14%) reported receiving liver specialty care during the follow-up period. In the multivariable model, we observed a clinically important although not statistically significant association between having been in substance abuse treatment and receiving liver specialty care (adjusted odds ratio = 1.38; 95% confidence interval = 0.9–2.11). Substance abuse treatment systems should give attention to the need of patients to receive care for prevalent treatable diseases such as HIV/HCV coinfection and facilitate its medical care to improve the quality of care for individuals with substance use disorders. The data illustrate the need for clinical care models that give explicit attention to the coordination of primary health care with addiction and hepatitis C specialty care while providing ongoing support to engage and retain these patients with complex health needs.     

Flourishing,languishing and moderate mental health: Prevalence and change in mental health during recovery from drug and alcohol problems

The aim was to explore the utility of Keyes’ concept of mental health in a substance addiction context. Mental health is considered the presence of emotional wellbeing in conjunction with high levels of social and psychological functioning. Using Keyes' measure, the frequency of languishing and flourishing is compared between clients who became abstinent and those continuing to use substances following treatment. It was hypothesised that there would be a significant interaction between substance use and levels of mental health over time. Participants were 794 individuals (79.5% male) attending residential substance abuse treatment provided by The Australian Salvation Army. The current sample was drawn from a larger longitudinal study evaluating routine client outcomes. At entry to treatment there were higher rates of languishing compared to population estimates, yet greater rates of flourishing at all time points compared to community normative data. There was a significant interaction between continuous mental health and substance use status. Mental health was rated significantly higher by individuals who were abstinent than those who had used substances at 3-month post-discharge follow-up. The comorbidity of mental illness and substance misuse has previously been investigated, but this is the first study to investigate the prevalence of mental health. While participants who remained abstinent achieved the highest levels of flourishing, at follow-up there were lower rates of languishing than found in a general community sample. Additionally, results suggested that improved mental health was a consequence of reduced severity of alcohol and other drug abuse, and followed reductions in cravings.     

Treatment of dually diagnosed clients

Up to 80% of people with mental and emotional disorders have abused or will abuse street drugs or alcohol at some point in their lives. Similarly, over half of people with substance use disorders are also diagnosed with a mental disorder at some point. In clinical populations and institutional settings, the numbers are far higher. The term dual diagnosis (coexisting mental and substance use disorders) refers to a large and complex group of people. This article addresses general issues regarding the complexities of dual diagnosis--differential diagnosis, the difficulty of achieving abstinence for people who perceive significant benefits from drug use, and the problems due to the historical split between the mental health and substance abuse treatment systems. Harm reduction, an approach to treating drug-using clients that focuses on the damage done by drugs and alcohol without insisting on abstinence from all psychoactive substances, can offer a useful way of conceptualizing treatment of dual diagnosis. A treatment group specifically designed for dually diagnosed clients is described. This group, inspired by the idea that changes in addictive behavior occur in a series of stages and that motivation can be influenced by the quality of the relationship with the treatment provider, uses a drop-in structure to provide low-threshold access to supportive treatment, to meet clients "where they are."     

Modified therapeutic community for co-occurring disorders: a summary of four studies

This article summarizes results from four research studies (n = 902) that examined the effectiveness of the modified therapeutic community (MTC) for clients with co-occurring disorders (most with severe mental disorders). Significantly better outcomes for MTC were found across four experimental versus control comparisons on 23.1% (12 of 52) of primary outcome measures of substance use, mental health, crime, HIV risk, employment, and housing. Study limitations included the potential for selection bias, limited measurement of program fidelity, and insufficient examination of the relationship between treatment dose and outcome. Future research should emphasize clinical trial replications, multiple outcome domains, and further development of continuing care models. Given the need for research-based approaches, the MTC warrants consideration when program and policy planners are designing programs for co-occurring disorders.     

Aftercare attendance and post-treatment functioning of severely substance dependent residential treatment clients

The present study evaluated the impact of a structured aftercare programme following residential treatment for severe alcohol and/or heroin dependent clients. Over 17 months, 77 participants were recruited to the study and allocated randomly to either a structured aftercare (SA) programme or to unstructured aftercare (UA) of crisis counselling on request. Independent clinicians interviewed participants and collaterals, at 4-month (median) intervals, for 12 months following residential treatment. SA compared to UA was associated with a fourfold increase in aftercare attendance and one-third the rate of uncontrolled principal substance use at follow-up. Participants who attended either type of aftercare relapsed a median of 134 days later than those who attended no aftercare. Overall, 23% of monitored participants remained abstinent throughout, 21% maintained controlled substance use and 56% relapsed, within a median of 36 days following residential treatment. The only significant predictor of days to relapse, controlling for age, was pretreatment use of additional substances. Participants with pretreatment additional substance use relapsed a median of 192 days earlier than those who had used no other substances. The degree of agreement between participant self-reports and collateral reports was fair-to-moderate and moderate among collaterals. Intention-to-treat analyses revealed significant and clinically meaningful reductions in substance use in this sample of severely dependent residential treatment clients. The generalizability of these results is limited because of significant differences in age and presenting substance between the study sample and other clients admitted to the service during the study. This latter group of younger, male, heroin-dependent clients with polydrug use who refuse opioid pharmacotherapy, are more likely to drop out of treatment or relapse early following treatment and continue to present a challenge to treatment services.

A day treatment program in a therapeutic community setting: six-month Outcomes : The Walden House Day Treatment Program

Although not well represented in the literature, day treatment programs targeting substance abuse problems have increased in both number and acceptability in recent years. This article reports on a day treatment program based on the Therapeutic Community (TC), and on outcomes for a sample of substance abuse clients (n = 66) entering the program. Participants were interviewed early in treatment and 6 months after admission using the Addiction Severity Index (ASI) and other measures. Clients entering day treatment were demographically diverse, with serious substance-abuse problems and psychiatric morbidity. Median retention in day treatment was about 5 weeks, but many clients received a contiguous episode of residential treatment, so that the median for total time in treatment was 18 weeks. Clients located and interviewed at 6-month follow-up (n = 38) showed significant improvement in alcohol and drug use, legal and social problems, and psychiatric symptoms. Findings suggest that day treatment can be used effectively as a precursor to residential treatment and that some clients applying for residential treatment can be treated effectively in day treatment alone.
