Comparing Hatha yoga with dynamic group psychotherapy for enhancing methadone maintenance treatment: a randomized clinical trial

BACKGROUND: As more methadone treatment programs are funded in an attempt to curb substance abuse and HIV infection among i.v. drug users, more cost effective treatment approaches are being sought. OBJECTIVES: To investigate whether clients in outpatient methadone maintenance treatment who practice weekly Hatha yoga in a group setting experience more favorable treatment outcomes than those who receive conventional group psychodynamic therapy. METHODS: After a 5-day assessment period, 61 patients were randomly assigned to methadone maintenance enhanced by traditional group psychotherapy (ie, conventional methadone treatment) or an alternative Hatha yoga therapy (ie, alternative methadone treatment). Patients were followed for 6 months and evaluated on a variety of psychological, sociological, and biological measures. The revised Symptom Check List provided the primary psychological measures; the Addiction Severity Index provided various indices of addictive behaviors. RESULTS: The evidence revealed that there were no meaningful differences between traditional psychodynamic group therapy and Hatha yoga presented in a group setting. Both treatments contributed to a treatment regimen that significantly reduced drug use and criminal activities. Psychopathology at admission was significantly related to program participation regardless of treatment group. DISCUSSION: In addition to examining the characteristics of patients who present for treatment, this study identifies unexpected staff issues that complicate the integration of alternative and traditional treatment strategies. CONCLUSION: Alternative methadone treatment is not more effective than conventional methadone treatment, as originally hypothesized. However, some patients may benefit more from alternative methadone treatment than conventional methadone treatment. Additional research is necessary to determine characteristics that identify patients who might benefit from alternative methadone treatment.     

The National Treatment Outcome Research Study in the United Kingdom: Six-month follow-up outcomes.

The National Treatment Outcome Research Study is the first prospective, multisite treatment outcome investigation of drug users in the United Kingdom. The findings of this influential national study are being used by the Department of Health to formulate purchasing guidance. This article presents data on substance use problems for clients (N?=?1,075) in specialist inpatient, rehabilitation, methadone maintenance, and methadone reduction modalities. The most frequent problem was heroin addiction with associated polydrug use problems. There were differences between modalities in substance use at intake. Clients in residential modalities were older, were more likely to use cocaine and alcohol in addition to opiates, had longer drug careers, and had more previous treatment contact. Substantial improvements in a range of substance use problems were observed at 6-month follow-up among clients in all treatment modalities.

Comparable efficacy of contingency management for cocaine dependence among African American, Hispanic, and White methadone maintenance clients.

Cocaine use is a significant problem among methadone maintenance clients. Contingency management (CM) is a reinforcement-based approach with demonstrated efficacy for reducing cocaine use. This study examines whether the efficacy of CM treatment for cocaine-dependent individuals receiving methadone maintenance for opioid dependence differs by ethnicity. Participants were 191 African American, Hispanic, and White cocaine-dependent methadone maintenance clients, randomly assigned to standard methadone treatment or standard methadone treatment plus CM for 12 weeks. Hispanic participants were younger, less educated, and reported fewer years of cocaine use than did African American and White participants and reported fewer years of heroin use than did African American participants. African American participants were less likely to report a history of psychiatric symptoms or treatment in comparison with Hispanic and White participants. While CM was associated with longer duration of continuous cocaine abstinence and a greater proportion of submitted urine samples negative for cocaine, ethnicity was not related to treatment outcomes, and there was no significant interaction between treatment and ethnicity. CM appears to be an efficacious treatment for cocaine dependence among methadone maintenance clients, regardless of ethnicity. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Dependent opioid users assessed for methadone treatment in Otago: patterns of drug use

AIMS: To provide detailed information about the types of drugs used and the patterns of drug use for injecting drug users presenting for methadone treatment. METHODS: A retrospective case note review was carried out for 126 consecutive clients who were assessed for methadone treatment in the Otago province over a 2 year period. Patterns of drug use in the three months prior to presentation were recorded. RESULTS: Over 60% of those presenting were using three or more opioid drugs, with the most common being homebake (63%), sustained release morphine sulphate tablets (62%), buprenorphine (52%), opium poppies (50%) and methadone (41%). Use of diacetylmorphine (heroin) was reported primarily by those returning from recent overseas travel. Most clients reported the regular use of multiple other of clients using benzodiazepines daily. Almost 80% of the group were regular tobacco smokers and 11% showed evidence of alcohol disorders (abuse or dependence). Low levels of use were reported for cocaine, amphetamines, and hallucinogens. CONCLUSION: These patterns of drug use have important implications for the planning of methadone treatment programmes.     

Experience-seeking characteristics of methadone clients.

The following scales were administered to 32 clients (mean age 34.09 yrs) of a methadone program and a demographically matched normal control group of 32 Ss (mean age 32.16 yrs): modified version of Pearson's Novelty-Experiencing Scale, her Desire-for-Novelty Scale, and Vando's Reducer-Augmenter Scale. Methadone Ss scored higher than controls on measures reflecting boredom, desire for change, and attraction to physically thrilling activities. Correlations of these measures with length of most recent dependency before treatment, time on program, and time since initial dependency suggest that the demonstrated peculiarities of the methadone clients probably antedated their involvement with opiate drugs.

Contingency management for cocaine use in methadone maintenance patients: When does abstinence happen?

Contingency management (CM) is an efficacious intervention for cocaine abusing methadone patients, but typically only about half of patients respond. By investigating time to onset of cocaine abstinence and factors associated with abstinence, we may be able to more efficiently direct CM approaches to patients most likely to benefit. Onset of cocaine abstinence was evaluated in cocaine abusing methadone maintenance patients (N = 193) enrolled in one of three randomized clinical trials of CM. Participants received standard treatment with frequent urine toxicology monitoring or standard treatment plus CM during the trials. Slightly more than half the sample obtained at least 1 week of cocaine abstinence, and approximately a third of the sample obtained at least 4 weeks of cocaine abstinence. Discrete-time survival and hazard analyses found Weeks 1 and 2 of the intervention period had the greatest probability for the initiation of abstinence, and few participants initiated any period of abstinence after Week 4. Patients randomized to CM, those with more years of cocaine use, and those with less recent cocaine use were more likely to achieve abstinence. Overall, these results indicate onset of cocaine abstinence is likely to occur early in treatment and in individuals with less severe cocaine use. Practical implications of these results for designing and implementing CM interventions in methadone maintenance clinics are discussed.

Program diversity and treatment retention rates in the Drug Abuse Treatment Outcome Study (DATOS).

Stays of 3 months or longer in drug abuse treatment generally predict better follow-up outcomes. In a national sample of community-based programs that participated in the Drug Abuse Treatment Outcome Study, median lengths of stay were 3 months for clients in long-term residential and outpatient drug-free treatments and 1 year for clients in outpatient methadone treatment. However, individual programs within each of these modalities differed widely in how long they kept their clients in treatment as well as their service delivery. Programs treating individuals with heavier cocaine and alcohol use and more psychological dysfunction usually had shorter retention rates. Nonetheless, even after statistically controlling for these client differences, some programs were more effective than others in engaging and retaining clients.

Risk factors in the relationship between gender and crack/cocaine.

Female inner-city substance users evidence greater crack/cocaine use and are more likely to be dependent on this drug than on any other drug. Additionally, female inner-city substance users evidence greater crack/cocaine use and are more likely to be dependent on this drug than their male counterparts, despite no consistent difference demonstrated in use and dependence across other drugs. Because no published work has empirically examined the factors underlying this link between females and crack/cocaine, the current study examined the role of theoretically relevant personality and environmental variables. Among 152 (37% female) individuals in a residential substance-use treatment program, females evidenced greater use of crack/cocaine (current and lifetime heaviest) and were significantly more likely to evidence crack/cocaine dependence than their male counterparts. In contrast, no gender differences were found for any other substance across alcohol, cannabis, and hallucinogens (including PCP). Surprisingly, females were more impulsive than their male counterparts, with impulsivity serving as a risk factor in the relationship between gender and crack/cocaine dependence and lifetime heaviest use. Females also evidenced higher levels of negative emotionality and childhood abuse, but neither variable served as a risk factor in the relationship between gender and crack/cocaine dependence or use. Limitations and future directions are discussed, including the need for further exploration of impulsivity across its various dimensions as well as the inclusion of additional variables such as social context variables to account more fully for this complex link between gender and crack/cocaine.

A randomized controlled trial of the therapeutic workplace for community methadone patients: A partial failure to engage.

The Therapeutic Workplace is an employment-based treatment for drug addiction that uses wages for work to reinforce drug abstinence. The Therapeutic Workplace has promoted abstinence from heroin and cocaine in treatment-resistant mothers in methadone treatment. This study attempted to replicate that effect in crack cocaine users recruited from community-based methadone programs. Participants were randomly assigned to a Therapeutic Workplace (n=22) or usual care control (n=25) group. Therapeutic Workplace participants were invited to work in the workplace and earn vouchers every weekday for 9 months contingent on documented opiate and cocaine abstinence. The two groups did not differ significantly on measures of cocaine or opiate use collected during study participation. Daily attendance and urinalysis results of the Therapeutic Workplace group were analyzed, and only 7 of the 22 participants initiated consistent periods of abstinence and workplace attendance. Two individuals gained access to the workplace on a few days, and 9 participants attempted to gain access to the workplace but never provided a drug-negative urine sample. Possible reasons for differences between the current study and the previous Therapeutic Workplace study are considered. Procedures that increase participant contact with the Therapeutic Workplace and its reinforcement contingencies might increase the likelihood of these individuals being successful in the treatment program.

Cannabis versus other illicit drug use among methadone maintenance patients.

Few data exist on the prevalence and consequences of cannabis use among methadone maintenance patients. Weekly urine toxicology data from 70 patients in a methadone program were analyzed for evidence of cannabis as well as cocaine and benzodiazepines, and the relationship between use of these drugs and opiate use was examined. Patients who were positive for both cocaine and benzodiazepine, but not those positive for cannabis, were more likely also to test positive for opiates. Related literature is reviewed, and the issue of illicit drug use among such patients is discussed in the context of harm reduction. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Concurrent alcohol dependence among methadone-maintained cocaine abusers is associated with greater abstinence.

Concurrent alcohol dependence (AD) among polysubstance abusers has been associated with negative consequences, although it may not necessarily lead to poor treatment outcomes. One of the most efficacious treatments for cocaine abuse is contingency management (CM), but little research has explored the impact of AD on abstinence outcomes, particularly among patients in methadone maintenance. Using data from three trials of CM for cocaine use, we compared baseline characteristics and posttreatment and follow-up cocaine outcomes between methadone-maintained, cocaine-dependent patients (N = 193) with and without concurrent AD, randomized to standard care (SC) with or without CM. Patients with and without concurrent AD had similar baseline characteristics, with the exception that AD patients reported more alcohol use. AD patients achieved longer durations of cocaine abstinence and were more likely to submit a cocaine-negative sample at follow-up than non-AD patients. Patients randomized to CM achieved better outcomes than those randomized to SC, but there was no interaction between treatment condition and AD status. These findings suggest that cocaine-using methadone patients with AD achieve greater cocaine abstinence than their non-AD counterparts and should not necessarily be viewed as more difficult to treat.

Viscoelastic adherence to corneal endothelium following phacoemulsification

OBJECTIVE: The study examined the prevalence and correlates of criminal victimization and the relationship between victimization and client outcomes for homeless clients with mental illness. METHODS: Subjects were clients in community treatment programs participating in the Access to Community Care and Effective Services and Supports (ACCESS) program of the Center for Mental Health Services. Data were obtained through interviews conducted at program entry and at three and 12 months after entry with ACCESS clients in 18 sites during the first year of program operation (N = 1,839). Self-reports of victimization during the past two months as well as data on sociodemographic, health, and social adjustment indicators were obtained at each time point. Multiple regression was used to determine both the correlates of victimization among this population and the effect of recent victimization on client outcomes three and 12 months after program entry. RESULTS: Forty-four percent of the clients were the victims of at least one crime during the two months before entering the program. Women were significantly more likely than men to have been victimized. Multivariate analysis showed that the more severe the client's psychotic symptoms, alcohol abuse, and criminal history, the more likely he or she was to have been victimized. Recent victimization had a significant impact on client outcomes in terms of increased homelessness and decreased quality of life. Victimization shortly before program entry was also the single most important predictor of victimization at both follow-up points. CONCLUSIONS: These findings suggest the critical need for service providers who work with homeless people with serious mental illness to assess the extent to which they have been victims of crime and to address issues of victimization and safety along with psychiatric and social adjustment problems.     

G542X as a probable Phoenician cystic fibrosis mutation

Only one prior study has examined social competence (SC) in drug addicted individuals. That study of cocaine-addicted individuals found gender differences in SC as well as differences based on the type of comorbid psychiatric diagnoses given. This study attempts to replicate findings from that cocaine study in a sample of opiate-addicted individuals and explores the relationship of SC to short-term treatment response. Gender differences in SC were examined in 28 women and 44 men attending a community methadone maintenance program. The question of differences in SC based on comorbid psychiatric diagnoses and treatment response were examined in a sample of 198 men attending a Veterans Administration methadone program. Women were found to have significantly lower SC than men. No significant differences in SC were revealed based on the presence of specific psychiatric diagnoses. SC was not related to short-term treatment response.     

Readmissions to drug abuse treatment and HIV risk behavior

The objectives of the study were (a) to investigate the characteristics of drug abuse treatment clients who return to treatment and (b) among those with readmissions, to describe changes over time in risk behavior for human immunodeficiency virus (HIV) infection and to identify factors associated with behavior change. Data were derived from a multisite HIV surveillance program in a single community; the program used a unique identifier to link HIV test results and behavioral information from multiple contacts. During a 30-month period, 1994 clients were admitted to three satellite facilities of a single treatment agency: detoxification, long-term residential, and outpatient. Of these clients, 574 (29%) had one or more readmissions to the same or a different facility during the 24 months following the index admission. Drug injectors, those tested for HIV, and those living in the community were more likely to be readmitted to treatment. There was little overall change in HIV risk behavior between the index admission and the readmission furthest in time from the index admission. Clients whose index visit was at the residential facility were more likely to reduce their injection risk behavior than those admitted to the other facilities. Clients readmitted to either the residential or the outpatient facility were more likely to have reduced their injection risk behavior than those readmitted to detoxification. Treatment facility was not associated with sexual risk behavior change. Men were more likely than women to reduce their high-risk sexual behaviors. The results underscore the need for treatment programs to make HIV testing readily available to their clients and to make special efforts to assist female clients to reduce their HIV risk.     

Predictive validity of cocaine, sedative, and alcohol dependence diagnoses.

This study examined the predictive validity of Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders-III-Revised (DSM-III-R) (R. L. Spitzer et al, 1990) based substance dependence diagnoses (i.e., cocaine, sedative, and alcohol) for 518 opioid-dependent outpatients entering methadone maintenance. Patients were followed over 1 year of treatment, which involved daily methadone substitution supplemented by individual and group counseling. Urine specimens were tested randomly 1–4 times per month. Patients diagnosed with current cocaine, sedative, or alcohol dependence were more likely to use these drugs than were patients with past only or no dependence syndrome. Current cocaine dependence predicted early treatment dropout. The results demonstrate the predictive and discriminant validity of several substance dependence diagnoses common among patients in substance abuse or other psychiatric treatment settings.

Mechanical alterations in smooth muscle from mice lacking desmin

The authors conducted formative research on the use of partner notification with HIV-infected drug users (i.e. those who use/abuse injectable drugs, crack or cocaine) in order to guide the development of an effective intervention for this population in New York City. Structured focus group and personal interviews were conducted with 25 in- and out-of-treatment drug users, 23 counsellors from a sexually transmitted disease (STD) clinic and a methadone maintenance treatment programme (MMTP), and nine experts in the field of HIV partner notification and/or substance abuse prevention and treatment. Results revealed factors associated with HIV-positive disclosure, the strengths and barriers of existing partner notification programmes and issues that should be considered in designing an effective intervention with HIV-infected drug users. Further research and planning activities are recommended before piloting and evaluating such a programme.     

Temporal patterns of heroin and cocaine use among methadone patients

A sample of 1,038 patients newly admitted to 15 methadone clinics in New York City were studied for up to three years in treatment or until discharge. Cluster analysis identified distinct patient groups with very different heroin and cocaine usage patterns during treatment. About 80% either started in or transitioned to a low heroin use group and 50% either started in or transitioned to a low cocaine use group during treatment. One-third of patients used cocaine extensively during treatment. Other "high risk" groups, such as those not recently employed, younger, or involved with criminal justice, could benefit from special interventions very early in treatment.     

Depressive symptoms among amphetamine and cocaine users before and after substance abuse treatment.

This study examined whether higher rates of depressive symptoms among amphetamine compared with cocaine users result from amphetamine use itself, polydrug use, or experiencing a major lifetime depressive episode and whether depressive symptoms among amphetamine users are more likely to persist 12 months after treatment. The association between amphetamine use and depressive symptoms disappears when controlling for polydrug use and lifetime major depressive episode. Polydrug use and lifetime depressive episode are significantly related to depressive symptoms in the year preceding treatment. Amphetamine use at intake does not predict depressive symptoms among individuals who are abstinent at follow-up, and amphetamine users are no more likely than cocaine users to report depression at a 12-month follow-up.
