Characteristics of older adult problem gamblers calling a gambling helpline.

BACKGROUND: Few investigations have characterized groups of older adults with gambling problems, and published reports are currently limited by small samples of older adult problem gamblers. Gambling helplines represent a widespread mechanism for assisting problem gamblers to move into treatment settings. Given data from older adult problem gamblers in treatment, we hypothesized that older as compared with younger adult problem gamblers calling a gambling helpline would be less likely to report gambling-related problems. DESIGN AND METHODS: Logistic regression analyses were performed on data obtained from January 1, 2000 to December 31, 2001, inclusive, from callers with gambling problems (N = 1,084) contacting the Connecticut Council on Problem Gambling Helpline. RESULTS: Of the 1,018 phone calls used in the logistic regression analyses, 168 (16.5%) were from older adults and 850 (83.5%) from younger adults. Age-related differences were observed in demographic features, types and patterns of gambling reported as problematic, gambling-related problems and psychiatric symptoms, substance use problems, patterns of indebtedness, and family histories of addictive disorders. Older as compared with younger adult problem gamblers were more likely to report having lower incomes, longer durations of gambling, fewer types of problematic gambling, and problems with casino slot machine gambling and less likely to report gambling-related anxiety, family problems, illegal behaviors and arrests, drug problems, indebtedness to bookies or acquaintances, family histories of drug abuse, and problems with casino table gambling. CONCLUSIONS: Older as compared with younger adult problem gamblers calling a gambling helpline differ on many clinically relevant features. The findings suggest the need for improved and unique prevention and treatment strategies for older adults with gambling problems.

Stress-induced cocaine craving and hypothalamic-pituitary-adrenal responses are predictive of cocaine relapse outcomes.

BACKGROUND: Cocaine dependence is associated with high rates of relapse. Stress and drug cue exposure are known to increase cocaine craving and stress arousal, but the association between these responses and cocaine relapse has not been previously studied. OBJECTIVE: To examine whether stress-induced and drug cue-induced cocaine craving and hypothalamic-pituitary-adrenal axis responses evoked in the laboratory are associated with subsequent cocaine relapse. DESIGN: Prospective study design assessing cocaine relapse and drug use during a 90-day follow-up period after discharge from inpatient treatment and research. Data were analyzed by Cox proportional hazards regression and multiple regression. SETTING: Inpatient treatment and research unit in a community mental health center. PATIENTS: Forty-nine treatment-seeking cocaine-dependent individuals. MAIN OUTCOME MEASURES: Time to cocaine relapse, number of days of cocaine use, and amount of cocaine used per occasion in the follow-up phase. RESULTS: Greater stress-induced, but not drug cue-induced, cocaine craving was associated with a shorter time to cocaine relapse. Stress-induced corticotropin and cortisol responses predicted higher amounts of cocaine use per occasion in the 90-day follow-up. CONCLUSIONS: These results demonstrate that stress-related increases in cocaine craving and hypothalamic-pituitary-adrenal axis responses are each associated with specific cocaine relapse outcomes. The findings support the use of stress-induced drug craving and associated hypothalamic-pituitary-adrenal axis responses to evaluate cocaine relapse propensity. Furthermore, treatments that address stress-induced cocaine craving and hypothalamic-pituitary-adrenal responses could be of benefit in improving relapse outcomes in cocaine dependence.

The use of contingency management and motivational/skills-building therapy to treat young adults with marijuana dependence.

Marijuana-dependent young adults (N = 136), all referred by the criminal justice system, were randomized to 1 of 4 treatment conditions: a motivational/skills-building intervention (motivational enhancement therapy/cognitive-behavioral therapy; MET/CBT) plus incentives contingent on session attendance or submission of marijuana-free urine specimens (contingency management; CM), MET/CBT without CM, individual drug counseling (DC) plus CM, and DC without CM. There was a significant main effect of CM on treatment retention and marijuana-free urine specimens. Moreover, the combination of MET/CBT plus CM was significantly more effective than MET/CBT without CM or DC plus CM, which were in turn more effective than DC without CM for treatment attendance and percentage of marijuana-free urine specimens. Participants assigned to MET/CBT continued to reduce the frequency of their marijuana use through a 6-month follow-up.

A randomized controlled pilot study of motivational interviewing for patients with psychotic and drug use disorders.

AIMS: This pilot study examined the efficacy of a two-session motivational interview adapted for dually diagnosed psychotic and drug-related disordered patients (DDMI) in comparison to a two-session standard psychiatric interview (SI). DESIGN: The study used a randomized controlled trial design. Participants received either DDMI or SI and were assessed at baseline, 4-, 8- and 12-week follow-up points. The principal analysis for examination of treatment effects across time was a random effects regression model. SETTING: Both DDMI and SI interviews served as pre-admission intake interventions to an ambulatory specialty dual diagnosis intensive out-patient and partial hospital program. PARTICIPANTS: Forty-four treatment-seeking participants (DDMI = 24; SI = 20) who had co-occurring psychotic and drug-related disorders were assigned randomly to the treatment conditions. Measurements Primary outcomes were days of primary drug use, secondary drug use, alcohol use and psychotropic medication adherence, proportion of participants admitted into the program and days of attendance. FINDINGS AND CONCLUSIONS: DDMI and SI resulted in improved treatment outcomes, but there were no main effects for the sample as a whole. Separate examination of primary cocaine and primary marijuana using subsamples, however, suggested that DDMI resulted in significantly better primary drug treatment outcomes for the cocaine-using group, whereas SI resulted in significantly better primary drug treatment outcomes for the marijuana-using group. These findings indicate that MI may not work equally well for all types of psychotic disordered dually diagnosed patients and that alternative approaches may be as effective in fostering improved substance use treatment outcomes for subgroups of these individuals.

Comorbidity of substance use with depression and other mental disorders: from Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) to DSM-V.

AIMS: To arrive at recommendations for addressing co-occurring psychiatric and substance use disorders in the development of the Diagnostic and Statistical Manual of Mental Disorders fifth edition (DSM-V) criteria. METHODS: Synthesis of findings of other papers from a consensus conference and from the literature on diagnosis and treatment of co-occurring psychiatric and substance use disorders. Most of the relevant studies examine co-occurring depression. RESULTS: The diagnosis and treatment of psychiatric syndromes that co-occur with substance use disorders has been a source of controversy, fueled in part by limitations of pre-DSM-IV nosologies. The DSM-IV scheme of classifying co-occurring disorders as primary (also referred to as independent) or substance-induced has promise in terms of good predictive validity, although pertinent longitudinal and treatment studies are limited. The substance-induced category answers the need of clinicians for a way to categorize patients with clinically significant psychiatric symptoms that occur in the setting of ongoing substance use. CONCLUSIONS: DSM-V should retain the primary (independent) and substance-induced categories. In DSM-IV these categories are broadly defined and leave much to clinical judgement. Existing data sets should be brought to bear to refine the criteria, making them more detailed with clearer anchor points and more specificity around particular substances and psychiatric syndromes. More longitudinal studies and clinical trials are also needed. Looking beyond DSM-V, co-occurring psychiatric syndromes are likely to be important in the quest for a nosology founded on pathophysiology.

Neural activity associated with stress-induced cocaine craving: a functional magnetic resonance imaging study.

OBJECTIVE: Stress is known to increase cocaine craving and relapse risk in cocaine dependence. Identifying neural activity associated with stress and stress-induced cocaine craving is important in understanding the neurobiology of cocaine craving and relapse. METHOD: Blood oxygenation level dependent (BOLD) signal changes were assessed in a functional magnetic resonance imaging (fMRI) session with healthy controls and treatment-engaged, abstinent, cocaine-dependent individuals (patients) as they participated in brief guided imagery and recall of three personal stress and three personal neutral situations. RESULTS: During stress, patients showed significantly less BOLD activation than controls in specific frontal and para-limbic regions, such as the anterior cingulate (AC) region, left hippocampal/parahippocampal region, right fusiform gyrus, and the right postcentral gyrus. On the other hand, patients had increased activity in the caudate and dorsal striatum region during stress, activation that was significantly associated with stress-induced cocaine craving ratings. CONCLUSIONS: Patients failed to activate AC and related circuits during stress, regions associated with control, and regulation of emotion and distress states. Instead, they exhibited greater craving-related activation in the dorsal striatum, a region related to reward pathways and part of the obsessive-compulsive circuitry. Such functional alterations in stress processing may underlie the stress-related vulnerability to cocaine relapse often observed in cocaine-dependent individuals in early recovery.

Reasons for dropout from drug abuse treatment: symptoms, personality, and motivation.

Previous research has identified risk factors for early attrition from substance abuse treatment, but has not assessed reasons for dropout from the client's perspective. Interview and self-report assessment data were collected from 24 clients who prematurely terminated outpatient treatment to evaluate their subjective reasons for dropping out and the association of these reasons with demographic and clinical variables. Items from scales indicating problems with client motivation or conflicts with program staff were the most commonly endorsed. The severity of participant's symptoms and logistical problems interfering with appointments were less commonly reported as reasons for dropping out. Demographic, substance abuse, and motivational stage indicators were infrequently associated with subjective reasons for dropout. In contrast, indicators of maladaptive personality functioning were strongly associated with many reasons for dropping out, especially concerns about privacy and boundary issues within the program. Results from this preliminary evaluation will guide the development of an instrument and intervention focused on dropout risk factors and treatment reengagement.

We don't train in vain: a dissemination trial of three strategies of training clinicians in cognitive-behavioral therapy.

There has been little research on the effectiveness of different training strategies or the impact of exposure to treatment manuals alone on clinicians' ability to effectively implement empirically supported therapies. Seventy-eight community-based clinicians were assigned to 1 of 3 training conditions: review of a cognitive-behavioral therapy (CBT) manual only, review of the manual plus access to a CBT training Web site, or review of the manual plus a didactic seminar followed by supervised casework. The primary outcome measure was the clinicians' ability to demonstrate key CBT interventions, as assessed by independent ratings of structured role plays. Statistically significant differences favoring the seminar plus supervision over the manual only condition were found for adherence and skill ratings for 2 of the 3 role plays, with intermediate scores for the Web condition.

A structured approach to medical management: a psychosocial intervention to support pharmacotherapy in the treatment of alcohol dependence.

OBJECTIVE: Given the national trend toward integrating substance abuse treatment into medical practice, experts in the field of alcoholism designed a psychosocial, medically based intervention to be used with pharmacotherapy in the COMBINE multisite national study, supported by the National Institute on Alcohol Abuse and Alcoholism. A main purpose of the COMBINE Study is to investigate optimal treatment for patients with alcohol dependence by combining pharmacotherapy and psychosocial interventions. METHOD: The medically based intervention, called Medical Management (MM), was specifically constructed to be implemented by medically trained practitioners in nonspecialty settings. Each visit includes evaluations of medication safety and adherence, monitoring of alcohol use and direct advice to the patient for achieving full recovery. RESULTS: There are several themes implicit in MM. Patient education about the disorder and about the treatment being provided are both essential. The clinician also educates the patient about how he or she has been affected by alcohol dependence. Information is given on how to take the medication(s) as prescribed, what the patient should expect from the medication(s) and what kinds of events the clinician will need to know about during treatment. Finally, the clinician and patient discuss strategies for ensuring medication safety and adherence to the prescribed regimen. CONCLUSIONS: MM was easily implemented in the COMBINE Study with the aid of the MM Treatment Manual.

Looking for poppa: parenting status of men versus women seeking drug abuse treatment.

This survey of individuals seeking methadone maintenance treatment was pursued to document the parenting status of drug-dependent men and clarify ways their status as parents differs from that of drug-dependent women. Data concerning demographic characteristics, drug abuse history, and parenting status were systematically coded from the medical records of 362 men and 162 women seeking methadone maintenance treatment during a 12-month period. Analysis of parenting status by gender indicated that, although a greater proportion of women were the parent of at least one biological child, there were actually more fathers than mothers within the cohort. Among the parents, fathers were more likely to have been abusing opioids when they first became a parent, and they were more likely to be living away from their children. There were no significant gender differences in the number of children or the average age of children. The results suggested that fathering may be an important, but largely neglected, treatment issue for drug-abusing men.

Treatment of cocaine dependence and depression.

In common with all other classes of substance use disorders, cocaine dependence has been shown to be strongly associated with depression by community and clinical surveys. Diagnosing depression in cocaine abusers can be challenging because it is difficult to distinguish transient symptoms caused by cocaine from enduring depression syndromes. Nonetheless, both "substance-induced" and "independent" depression syndromes require clinical attention, especially when symptoms have been persistent and severe before entering treatment. Use of antidepressant medications for combined cocaine dependence and depression is supported by a preponderance of evidence from 4 randomized clinical trials (RCTs) that prospectively targeted both depression and cocaine dependence and 7 RCTs in which a post hoc analyses demonstrated efficacy in the subgroup of cocaine abusers with comorbid depression. Notably, most negative studies have evaluated SSRIs while positive studies have used agents such as desipramine or buproprion. A substantial clinical trials literature supports the efficacy of behavioral treatments for general populations of cocaine abusers and of patients with depression but few studies have addressed patients with both disorders. Treatment development and research are needed on models of care that truly integrate strategies for addressing both cocaine use and depression. Recent advances have paved the way for a new generation of research. These include validation of efficacious cocaine treatments, improved diagnostic methods, organization of the Clinical Trials Network and development of guidelines for managing methodological challenges posed by high rates of current medication use and polysubstance abuse in treatment entering cocaine abusers.

Preliminary validity and reliability testing of a structured clinical interview for pathological gambling.

The psychometric properties of a clinician-administered, DSM-IV-based, structured clinical interview for pathological gambling (SCI-PG) were examined. Seventy-two consecutive subjects requesting treatment for gambling problems were administered the SCI-PG. Reliability and validity were determined. Classification accuracy was examined using longitudinal course of illness. The SCI-PG demonstrated excellent inter-rater and test-retest reliability. Concurrent validity was observed with the South Oaks Gambling Screen (SOGS). Discriminant validity was observed with measures of anxiety and depression. The SCI-PG demonstrated both high sensitivity and specificity based on longitudinal assessment. The SCI-PG demonstrated excellent reliability and validity in diagnosing PG in subjects presenting with gambling problems. These findings require replication in other groups to examine their generalizability.

Choosing a behavioral therapy platform for pharmacotherapy of substance users.

Behavioral therapy platforms have become virtual requirements in pharmacotherapy trials due to their utility in reducing noise variability, preventing differential medication adherence and protocol attrition, enhancing statistical power and addressing ethical issues in placebo-controlled trials. Selecting an appropriate behavioral platform for a particular trial requires study-specific tailoring, taking into account both the stage of development of the medication being evaluated, as well as the specific strengths and weaknesses of a broad array of available empirically supported behavioral therapies and the range of their possible targets (e.g., enhancing medication adherence, preventing attrition, addressing co-morbid problems, fostering abstinence, and targeting specific weaknesses of the pharmacologic agent). Choosing a suitable behavioral platform also requires consideration of the characteristics of the population to be treated, stage of scientific knowledge regarding the medication's effects, appropriate balance of internal and external validity, and consideration of potential ceiling effects. Available manualized behavioral treatments are reviewed, noting their strengths and limitations as behavioral therapy platforms for pharmacotherapy trials and as potential concomitant therapies in clinical practice.

Opioid-, cannabis- and alcohol-dependent women show more rapid progression to substance abuse treatment.

UNLABELLED: Alcohol-dependent women progress faster from onset of alcohol drinking to entry into treatment, experiencing an earlier onset (i.e., "telescoping") of alcohol-related complications. This phenomenon also appears to be evident in drug-dependent women, though the data available to support telescoping in drug dependence is less abundant. OBJECTIVE: To evaluate gender effects on progression to treatment entry and on the frequency, severity and related complications of DSM-III-R drug and alcohol dependence among 271 substance-dependent patients (mean age: 32.6 years; 156 women). METHOD: Multivariate and univariate ANCOVA was used to compare age at onset of regular use of cocaine, opioids, cannabis and alcohol and time elapsed between initiation of regular use of each substance and entry into an index or current substance abuse treatment. Scores on the Addiction Severity Index (ASI) were also examined. RESULTS: There was no gender difference among patients in the age at onset of regular use of any substance. Women experienced fewer years of regular use of opioids and cannabis, and fewer years of regular alcohol drinking before entering treatment. Although the severity of drug and alcohol dependence did not differ by gender, women reported more severe psychiatric, medical and employment complications. CONCLUSIONS: These findings support the notion of an accelerated progression to treatment entry among opioid-, cannabis- and alcohol-dependent women, and suggest that there exists a gender-based vulnerability to the adverse consequences of these disorders.

Efficacy of disulfiram and cognitive behavior therapy in cocaine-dependent outpatients: a randomized placebo-controlled trial.

CONTEXT: Disulfiram has emerged as a promising treatment for cocaine dependence, but it has not yet been evaluated in general populations of cocaine users. OBJECTIVES: To compare the effectiveness of disulfiram therapy with that of a placebo condition in reducing cocaine use and to compare the effectiveness of 2 active behavioral therapies-cognitive behavior therapy (CBT) and interpersonal psychotherapy (IPT)-in reducing cocaine use. DESIGN: Randomized, placebo-controlled, double-masked (for medication condition), factorial (2 x 2) trial with 4 treatment conditions: disulfiram plus CBT, disulfiram plus IPT, placebo plus CBT, and placebo plus IPT. SETTING: A community-based outpatient substance abuse treatment program. PATIENTS: A total of 121 individuals meeting the criteria for current cocaine dependence. INTERVENTIONS: Patients received either disulfiram (250 mg/d) or placebo in identical capsules. Medication compliance was monitored using a riboflavin marker procedure. Both behavioral therapies (CBT and IPT) were manual guided and were delivered in individual sessions for 12 weeks. MAIN OUTCOME MEASURES: Random regression analyses of self-reported frequency of cocaine use and results of urine toxicology screens. RESULTS: Participants assigned to disulfiram reduced their cocaine use significantly more than those assigned to placebo, and those assigned to CBT reduced their cocaine use significantly more than those assigned to IPT (P<.01 for both). Findings were consistent across all study samples (eg, intention to treat, treatment initiators, and treatment completers). Benefits of disulfiram use and CBT were most pronounced for participants who were not alcohol dependent at baseline or who fully abstained from drinking alcohol during treatment. Adverse effects experienced by participants who received disulfiram were mild and were not considerably different from those experienced by participants who received placebo. CONCLUSIONS: Disulfiram and CBT are effective therapies for general populations of cocaine-dependent individuals. Disulfiram seems to exert a direct effect on cocaine use rather than through reducing concurrent alcohol use.

Sex differences in cocaine-dependent individuals' response to disulfiram treatment.

The objective of this study is to evaluate differential response to disulfiram treatment of cocaine dependence by sex. Sex by treatment interactions from two pooled randomized clinical trials involving 191 cocaine-dependent subjects (36% female) were evaluated. Primary outcomes were days of abstinence and percentage of drug-free urine specimens. Significant sex by treatment interactions were found, where men treated with disulfiram had better outcomes than those who were not. Women had an intermediate outcome regardless of whether they received disulfiram. Sex differences in response to disulfiram treatment have important clinical and theoretical implications. Reasons for this apparent sex-based response are not clear, but possible mechanisms worthy of greater study include differences in alcohol use by sex as well as differences in dopamine-mediated responses to cocaine and disulfiram.

Cost effectiveness of disulfiram: treating cocaine use in methadone-maintained patients.

Converging evidence suggests that disulfiram is a promising treatment for cocaine dependence. We study the cost-effectiveness of providing disulfiram to methadone-maintained opioid addicts in a randomized clinical trial setting. Our economic evaluation is based on a double blind clinical trial in which 67 cocaine-dependent methadone-maintained opioid-dependent subjects were randomized to get the additional treatment of disulfiram or placebo in a 12-week trial. Outcome measures used are the number of days of cocaine use and grams of cocaine per week. Cost measures used are the cost of providing standard methadone treatment and the incremental cost of adding disulfiram to the standard treatment. Cost measures of standard and disulfiram-enhanced treatment were collected retrospectively from the provider. Results from this cost-effectiveness analysis imply that, even though disulfiram increases slightly the cost of methadone treatment, its increase in effectiveness may be important enough to warrant its addition for treating cocaine dependence in methadone-maintained opiate addicts.
