Pre-treatment measures of impulsivity, aggression and sensation seeking are associated with treatment outcome for African-American cocaine-dependent patients.

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 \u27poor responders\u27 who may benefit from additional or alternative treatment approaches

Comparison of pretreatment characteristics and treatment outcomes for alcohol-, cocaine-, and multisubstance-dependent patients.

We investigated whether pretreatment characteristics and measures of outcome differed for alcohol-, cocaine-, and multisubstance-dependent patients receiving outpatient substance abuse treatment. One hundred and forty substance dependent individuals (32 alcohol, 76 cocaine, and 32 multisubstance) enrolled in a 12-week outpatient treatment program were compared across measures of addiction severity, personality, and treatment-readiness at admission. In-treatment, end-of-treatment and 9-month follow-up assessments of treatment outcome were then compared across the three groups. Outcome measures included reduction in problem severity, abstinence, retention, number of sessions attended, dropout, and counselor and patient ratings of treatment benefit. At admission, the multisubstance group had a higher proportion of positive urines, reported more severe drug, alcohol and psychiatric problems, and displayed higher impulsivity and anxiety scores than one or both of the other groups. However, multisubstance patients were more treatment ready in terms of adopting a total abstinence orientation than alcohol or cocaine patients. While a significant reduction in symptoms occurred for the total sample during treatment as well as at follow-up, comparisons of outcomes did not consistently favor any particular group. The three groups had equivalent improvements in eleven of fourteen during-treatment and five of seven follow-up measures. Despite pretreatment differences, in severity and treatment-readiness, outcomes were more similar than different for alcohol-, cocaine-, and multisubstance-dependent patients. Clinicians should be cautious about forecasting treatment-outcomes for addicted patients based on their primary substances of abuse

Books in Arabic Script

The chapter approaches the book in Arabic script as the indispensable means for the transmission of knowledge across Eurasia and Africa, within cultures and across cultural boundaries, since the seventh century ad. The state of research can be divided into manuscript and print studies, but there is not yet a history of the book in Arabic script that captures its plurilinear development for over fourteen hundred years. The chapter explores the conceptual and practical challenges that impede the integration of the book in Arabic script into book history at large and includes an extensive reference list that reflects its diversity. The final published version was slightly updated, and includes seven illustrations of six Qurans from the holdings of Columbia University Libraries, four manuscripts and two printed versions. Moreover, the illustrations are images of historical artifacts which are in the public domain - despite Wiley's copyright claim

An investigation into the effects of participation in a co-operative as compared to a competitive task on intra-group attitudes of acceptance and rejection.

Typewritten ms.[...] The present investigation attempts to study the age old problem of competition as compared to co-operation. Here is a present day, practical problem, much in the public eye and mind, much experimented upon, much discussed and very much more theorized about. However, in conformity with what has been said thus far, we wish to pursue this investigation in the manner of a personalistic analysis. We are not Interested, here, in the comparative efficiency of one method over the other as a general law applied to individuals. We are interested in the individual, in his happiness, his well- being, his future, his morale and how competition and co-operation affects him in these ways

Comorbidity of alcohol and gambling problems in emerging adults: A bifactor model conceptualization.

Addictive disorders, such as pathological gambling and alcohol use disorders, frequently co-occur at greater than chance levels. Substantive questions stem from this comorbidity regarding the extent to which shared variance between gambling and alcohol use reflects a psychological core of addictive tendencies, and whether this differs as a function of gender. The aims of this study were to differentiate both common and unique variance in alcohol and gambling problems in a bifactor model, examine measurement invariance of this model by gender, and identify substantive correlates of the final bifactor model. Undergraduates (N = 4475) from a large northwestern university completed an online screening questionnaire which included demographics, quantity of money lost and won when gambling, the South Oaks Gambling Screen, the AUDIT, gambling motives, drinking motives, personality, and the Brief Symptom Inventory. Results suggest that the bifactor model fit the data well in the full sample. Although the data suggest configural invariance across gender, factor loadings could not be constrained to be equal between men and women. As such, general and specific factors were examined separately by gender with a more intensive subsample of females and males (n = 264). Correlations with motivational tendencies, personality traits, and mental health symptoms indicated support for the validity of the bifactor model, as well as gender-specific patterns of association. Results suggest informative distinctions between shared and unique attributes related to problematic drinking and gambling

Patient treatment choice and compliance: Data from a substance abuse treatment program

The authors tested the hypothesis that patients (treatment-seeking cocaine-dependent persons) given the opportunity to choose between treatment approaches would do better than patients randomly assigned to the same approaches in treatment retention and 9-month outcome. Subjects were 34 patients who voluntarily chose to enter individual therapy 1 hour per week (IND) and 33 who chose intensive group therapy for 3 hours, 3 times weekly (INT). There were no significant differences between these two groups on demographic, personality, or addiction severity variables or in treatment retention or 9-month outcome. Comparison with samples of 30 patients who had been randomly assigned to IND and 30 to INT did not confirm the hypothesis that patients who chose their treatment would either remain in treatment for longer periods of time or manifest improved 9-month outcomes. The authors raise several motivational issues
