History and significance of childhood attention deficit disorder in treatment-seeking cocaine abusers

Thirty-five percent of 298 treatment-seeking cocaine abusers met DSM-III-R criteria for childhood attention deficit hyperactivity disorder (ADHD). Subjects with childhood ADHD were likely to be male (78%), meet Research Diagnostic Criteria (RDC) for conduct disorder (93%) and antisocial personality disorder (47%), and report a history of conduct disorder in first-degree relatives. With respect to those without the disorder and regardless of co-occurrence with sociopathy, cocaine abusers with childhood ADHD were younger at presentation for treatment and reported more severe substance use, earlier onset of cocaine abuse, more frequent and intense cocaine use, intranasal rather than freebase or intravenous use of cocaine, higher rates of alcoholism, and more previous treatment. This pattern of cocaine use is consistent with clinical descriptions of self-medication of residual symptoms of ADHD in cocaine abusers. Data from this study suggest that there may be more cocaine abusers with a history of ADHD than previously recognized in clinical samples of cocaine users, and that these individuals may differ in clinically meaningful ways from those without childhood ADHD. Moreover, the poorer outcome of subjects with ADHD in this sample underlines the importance of identifying and treating residual symptoms of ADHD in cocaine abusers.

A placebo controlled trial of bupropion for smoking cessation in schizophrenia

BACKGROUND Schizophrenic patients have high rates of cigarette smoking compared with the general population. We compared sustained-release (SR) bupropion with placebo for smoking cessation in patients with schizophrenic disorders. We also examined how antipsychotic class predicts smoking cessation outcomes with bupropion. METHODS Thirty-two subjects meeting DSM-IV criteria for schizophrenia or schizoaffective disorder and nicotine dependence were randomized to bupropion SR (BUP, 300 mg/day) or placebo (PLA). Outcomes included treatment retention, smoking abstinence rates, expired breath carbon monoxide (CO) levels, psychotic symptoms, and medication side effects. RESULTS Bupropion significantly increased trial endpoint 7-day point prevalence smoking abstinence rates compared with placebo [BUP, 8/16 (50.0%), PLA, 2/16 (12.5%); chi(2) = 5.24, df = 1, p <.05], and reduced CO levels during the trial [Medication x Time interaction; Z = 3.09, p <.01]. Positive schizophrenia symptoms were not altered by BUP, but negative symptoms were significantly reduced. Atypical antipsychotic drug treatment enhanced smoking cessation responses to BUP. Major side effects were dry mouth, gastrointestinal symptoms, headache, and insomnia. CONCLUSIONS Our results suggest that 1) BUP enhances smoking abstinence rates compared with PLA in nicotine-dependent schizophrenic smokers; 2) BUP is well-tolerated and safe for use in these patients; and 3) atypical antipsychotics may enhance smoking cessation outcomes with BUP.

A comparative trial of psychotherapies for ambulatory cocaine abusers : relapse prevention and interpersonal psychotherapy

Despite the widespread use of psychotherapy as treatment for cocaine abuse, the effectiveness of psychotherapy has not been explored through clinical trials. Forty-two outpatients who met DSM-III criteria for cocaine abuse were randomly assigned to one of two forms of purely psychotherapeutic treatments of cocaine abuse, either relapse prevention (RPT) or interpersonal psychotherapy (IPT). Subjects assigned to relapse prevention were more likely than subjects in IPT to attain three or more continuous weeks of abstinence (57 versus 33%), be classified as recovered at the point of treatment termination (43 versus 19%), and complete treatment (67 versus 38%). Whereas these differences did not reach statistical significance, significant differences by treatment group did emerge when subjects were stratified by severity of substance use: Among the subgroup of more severe users, subjects who received RPT were significantly more likely to achieve abstinence (54 versus 9%) and be classified as recovered (54 versus 0%). Among the subgroups of subjects with lower severity of substance abuse, outcome was comparable for both treatment types. Comparison of results from this investigation with historical controls from a structurally similar pharmacotherapy trial suggests that purely psychotherapeutic treatments may be both viable and effective approaches for many ambulatory cocaine abusers.

Concurrent validity of the addiction severity index.

The concurrent validity of the Addiction Severity Index (ASI), a new scale for assessing a range of clinical dimensions in drug and alcohol abusers, was evaluated in 204 opiate addicts applying for treatment. This study is the first independent validation study of this measure. The ASI subscales were found to have good concurrent validity with self-report measures in the areas of psychological problems, social adjustment problems, legal problems, and employment problems (r = .55 to .39). Drug abuse problems showed limited concurrent validity and medical problems were not concurrently assessed in our study. Addicts with psychiatric diagnoses beyond opiate abuse were effectively identified by the ASI, and depressed addicts were particularly well screened with a sensitivity of 89 per cent and a specificity of 67 per cent. A cluster analysis demonstrated that the six ASI scales could be used to discriminate depressed addicts, antisocial addicts, and addicts without psychiatric disorders. Thus, the ASI was demonstrated to be a potentially important evaluation instrument for opiate addicts.

Psychotherapy in a New Key

Bargaining with reading habit is no need. Reading is not kind of something sold that you can take or not. It is a thing that will change your life to life better. It is the thing that will give you many things around the world and this universe, in the real world and here after. As what will be given by this psychotherapy in a new key, how can you bargain with the thing that has many benefits for you?

Computer-Assisted Delivery of Cognitive-Behavioral Therapy for Addiction: A Randomized Trial of CBT4CBT

OBJECTIVES This study evaluated the efficacy of a computer-based version of cognitive-behavioral therapy (CBT) for substance dependence. METHOD This was a randomized clinical trial in which 77 individuals seeking treatment for substance dependence at an outpatient community setting were randomly assigned to standard treatment or standard treatment with biweekly access to computer-based training in CBT (CBT4CBT) skills. RESULTS Treatment retention and data availability were comparable across the treatment conditions. Participants assigned to the CBT4CBT condition submitted significantly more urine specimens that were negative for any type of drugs and tended to have longer continuous periods of abstinence during treatment. The CBT4CBT program was positively evaluated by participants. In the CBT4CBT condition, outcome was more strongly associated with treatment engagement than in treatment as usual; furthermore, completion of homework assignments in CBT4CBT was significantly correlated with outcome and a significant predictor of treatment involvement. CONCLUSIONS These data suggest that CBT4CBT is an effective adjunct to standard outpatient treatment for substance dependence and may provide an important means of making CBT, an empirically validated treatment, more broadly available.

Gender differences in cocaine use and treatment response

Much of our understanding of treatment efficacy in drug abuse is based on male drug abusers. In order to determine if there are gender differences in baseline drug use and treatment response, we compared male and female cocaine abusers who participated in an outpatient randomized clinical trial (RCT) evaluating pharmacotherapies for cocaine abuse. Although females had more severe drug problems at intake, they were as successful as males in the RCT and more successful at 6-month follow-up.

Pretreatment Brain Activation During Stroop Task Is Associated with Outcomes in Cocaine-Dependent Patients

BACKGROUND Cognitive behavioral and related therapies for cocaine dependence may exert their effects, in part, by enhancing cognitive control over drug use behavior. No prior studies have systematically examined the neural correlates of cognitive control as related to treatment outcomes for cocaine dependence. METHODS Twenty treatment-seeking cocaine-dependent individuals performed a Stroop color-word interference task while undergoing functional magnetic resonance imaging (fMRI) prior to initiating treatment. The primary outcome measures were percent of urine drug screens negative for cocaine, percent days abstinent, and treatment retention. Correlations between regional brain activation during Stroop task performance and treatment outcome measures were analyzed. RESULTS During Stroop performance, individuals activated brain regions similar to those reported in nonaddicted individuals, including the anterior cingulate cortex, dorsolateral prefrontal cortex, parietal lobule, insula, and striatum. Activations at treatment onset correlated differentially with specific outcomes: longer duration of self-reported abstinence correlated with activation of ventromedial prefrontal cortex, left posterior cingulate cortex, and right striatum; percent drug-free urine screens correlated with striatal activation; and treatment retention correlated with diminished activation of dorsolateral prefrontal cortex. A modest correlation between Stroop effect and treatment retention was found. CONCLUSIONS The functions of specific brain regions underlying cognitive control relate differentially to discrete outcomes for the treatment of cocaine dependence. These findings implicate neurocircuitry underlying cognitive control in behavioral treatment outcome and provide insight into the mechanisms of behavioral therapies for cocaine dependence. They also suggest neural activation patterns during cognitive control tasks are more sensitive predictors of treatment response than behavioral measures.

Cue-dose Training with Monetary Reinforcement: Pilot Study of an Antiretroviral Adherence Intervention

AbstractOBJECTIVE: To assess the feasibility and efficacy of two interventions for improving adherence to antiretroviral therapy regimens in HIV-infected subjects compared with a control intervention. DESIGN: Randomized, controlled, pilot study. SETTING: Department of Veterans Affairs HIV clinic and community-based HIV clinical trials site. PARTICIPANTS: Fifty-five HIV-infected subjects on stable antiretroviral therapy regimens. Subjects were predominantly male (89%) and African American (69%), and had histories of heroin or cocaine use (80%). INTERVENTIONS: Four weekly sessions of either nondirective inquiries about adherence (control group, C), cue-dose training, which consisted of the use of personalized cues for remembering particular dose times, and feedback about medication taking using Medication Event Monitoring System (MEMS) pill bottle caps, which record time of bottle opening (CD group), or cue-dose training combined with cash reinforcement for correctly timed bottle opening (CD+CR). MEASUREMENTS: Opening of the pill bottle within 2 hours before or after a predetermined time was measured by MEMS. RESULTS: Adherence to the medication as documented by MEMS was significantly enhanced during the 4-week training period in the CD+CR group, but not in the CD group, compared with the control group. Improvement was also seen in adherence to antiretroviral drugs that were not the object of training and reinforcement. Eight weeks after training and reinforcement were discontinued, adherence in the cash-reinforced group returned to near-baseline levels. CONCLUSIONS: Cue-dose training with cash reinforcement led to transient improvement in adherence to antiretroviral therapy in a population including mostly African Americans and subjects with histories of drug abuse. However, we were not able to detect any sustained improvement beyond the active training period, and questions concerning the timing and duration of such an intervention require further study. Randomized, controlled clinical studies with objective measures of adherence can be conducted in HIV-infected subjects and should be employed for further evaluation of this and other adherence interventions.

Personality, temperament, and character dimensions and the DSM-IV personality disorders in substance abusers.

The authors evaluated the relationship between P. T. Costa and R. R. McCraes (1992) NEO 5-factor model, C. R. Cloningers (1993) 7-factor Temperament and Character Inventory (TCI), and the American Psychiatric Associations (1994) Diagnostic and Statistical Manual of Mental Disorders, 4th ed., personality disorders in 370 inpatient and outpatient alcohol, cocaine, and opiate abusers. NEO Neuroticism was associated with many disorders, and different patterns for Agreeableness, Conscientiousness, and Extraversion emerged for the different disorders. Several TCI scales were associated with different personality disorders, although not as strongly as the NEO dimensions. Results did not support most predictions made for the TCI. Normal personality dimensions contributed significantly to the prediction of personality disorder severity above and beyond substance abuse and depression symptoms.
