We investigated whether measures of impulsivity, aggression and sensation seeking differed between cocaine-dependent subjects and controls, and whether these measures were related to treatment-outcome for cocaine patients. Pre-treatment assessments of impulsivity (Barratt Impulsivity Scale [BIS]), aggression (Buss-Durkee Hostility Inventory [BDHI]) and sensation seeking (Zuckerman Sensation Seeking Scale [SSS]) were obtained for 141 African-American cocaine-dependent patients entering a 12-week, intensive outpatient treatment program and 60 controls. The outcome measures were number of negative urine drug screens, days in treatment, dropout rates and number of treatment sessions. Cocaine patients reported significantly higher scores on the SSS, the BIS and the BDHI than controls. Furthermore, the SSS scores showed a significantly negative correlation with days in treatment and negative urines, and a significant positive correlation with the dropout rate. The BIS and the BDHI scores were significantly associated with days in treatment and dropout rates respectively. A combination of the three variables contributed significantly toward predicting retention and abstinence. Higher levels of pretreatment impulsivity and aggression and sensation seeking seem to associated with poor treatment outcome for cocaine dependent patients receiving intensive outpatient treatment. Combining these behavioral measures with other clinical predictors may help in early identification of 'poor responders' who may benefit from additional or alternative treatment approaches.

In an attempt to understand the reasons behind the high prevalence of tobacco smoking in patients with schizophrenia, the study examined whether specific symptoms of schizophrenia were associated with smoking. Standardized assessments of nicotine dependence (Fagerstrom Test for Nicotine Dependence) and psychopathology (Positive and Negative Syndrome Scale) were performed on 87 inpatients with schizophrenia. Nearly 76% of patients were nicotine dependent. Significant positive correlations were found between Fagerstrom scores and the total negative symptom score and scores on the negative symptom subscales of blunted affect, social withdrawal, difficulty in abstract thinking, and stereotyped thinking. Fagerstrom scores were also significantly associated with impairment in attention, orientation, thinking, and impulse control. Positive symptoms were not significantly associated with smoking. A combination of negative symptoms, duration of illness, and alcohol use optimally predicted smoking in the sample. Neurobiological mechanisms could possibly underlie some of our findings and require further investigation.

Cravings for alcohol are identified as a trigger for relapse, though laboratory studies of cravings produce mixed results in predicting relapse. The objective of this analysis is to assess the usefulness of craving as a predictor of relapse by assessing 218 adult, alcohol-dependent patients admitted to two separate residential addiction treatment programs. Days craving reported in the week prior to discharge predicted alcohol use at three-month follow-up. Admission spirituality, alcohol-refusal self-efficacy, and depression levels differentiated cravers from non-cravers. Patients who crave alcohol in residential treatment may be at higher relapse risk and identified by intake assessments of self-efficacy, depression, and spirituality.

Background and Objectives Illicit drug use, particularly of cannabis, is common among opiate-dependent individuals, and has the potential to impact treatment in a negative manner. Methods To examine this, patterns of cannabis use prior to and during methadone maintenance treatment (MMT) were examined to assess possible cannabis-related effects on MMT, particularly during methadone stabilization. Retrospective chart analysis was used to examine outpatient records of patients undergoing MMT (n=91), focusing specifically on past and present cannabis use and its association with opiate abstinence, methadone dose stabilization, and treatment compliance. Results Objective rates of cannabis use were high during methadone induction, dropping significantly following dose stabilization. History of cannabis use correlated with cannabis use during MMT, but did not negatively impact the methadone induction process. Pilot data also suggested that objective ratings of opiate withdrawal decrease in MMT patients using cannabis during stabilization. Conclusions and Scientific Significance The present findings may point to novel interventions to be employed during treatment for opiate dependence that specifically target cannabinoid-opioid system interactions.
