This study assessed personality disorders (PDs) in 158 alcohol-dependent outpatients (62 manifesting cocaine abuse and 96 without cocaine abuse) with the International Personality Disorders Examination interview between 2003 and 2006. Thirty-nine alcohol-dependent/cocaine abusers (62.9% of this group) and 51 only alcohol-dependent patients (53.1% of this group) manifested at least one PD. There were no statistically significant differences between groups in the overall prevalence rate of PDs. The most prevalent PDs, among the alcohol-dependent/cocaine abusers, were antisocial (21%), narcissistic (14.5%), and borderline (11.3%) PDs. The most frequently diagnosed PDs among the only alcohol-dependent patients were obsessive-compulsive (20.8%), paranoid (10.4%), and dependent (9.4%) PDs. There were significant differences between the groups. The study limitations are discussed.

    ABSTRACT: The aim of this paper was to describe the psychopathological and personality profile associated with cannabis dependence in young adults and to compare it with those of non-addictive disorders and the normal population. The sample consisted of 141 cannabis-dependent subjects attending a psychiatric outpatient clinic, 140 psychiatric patients with non-addictive disorders and 140 subjects from the general population chosen to match the patient samples for age, gender and socioeconomic level. All participants were assessed with different instruments related to personality (Impulsiveness Scale, Sensation-Seeking Scale and STAI) and psychopathology (SCL-90-R, BDI, STAI and Inadaptation Scale). Patients from the clinical groups presented more anxiety and depression symptoms than healthy participants, and had more problems adjusting to everyday life, but there were no differences between the two clinical groups. Cannabis-dependent patients were specifically characterized by low educational level and by the presence of paranoid ideation; they were also more impulsive and sensation-seeking than those from the other two groups. We discuss the implications of this study for clinical practice and for further research.

    ABSTRACT: The present study compares the prevalence rates of 12 personality disorders (PDs) among patients with alcohol, drug, and dual dependence through chi-square tests and analyses of variance. It further investigates possible predictors of these PDs through multiple linear regression analyses. Data were gathered in 2007-2008 among 274 patients admitted to intensive, residential substance abuse treatment programs in Belgium, using the ADP-IV (Assessment of DSM-IV Personality Disorders), the EuropASI (European version of the Addiction Severity Index), and the MINI (Mini International Neuropsychiatric Interview). The analyses showed that drug- and dual-dependent patients have higher PD prevalence rates than alcohol-dependent patients. The severity, but not the nature of the dependence, appears as an important predictor for personality pathology.

    ABSTRACT: To determine whether the additional interventions to standard care are cost-effective in addressing cocaine and alcohol abuse at 4 months (4 M) and 12 months (12 M) from baseline. We conducted a cost-effectiveness analysis of a randomized controlled trial with three arms: (1) NIDA's Standard intervention (SI); (2) SI plus a Well Woman Exam (WWE); and, (3) SI, WWE, plus four Educational Sessions (4ES). To obtain an additional cocaine abstainer, WWE compared to SI cost $7,223 at 4 M and $3,611 at 12 M. Per additional alcohol abstainer, WWE compared to SI cost $3,611 and $7,223 at 4 M and 12 M, respectively. At 12 M, 4ES was dominated (more costly and less effective) by WWE for abstinence outcomes. To our knowledge, this is the first cost-effectiveness analysis simultaneously examining cocaine and alcohol abuse in women. Depending on primary outcomes sought and priorities of policy makers, peer-delivered interventions can be a cost-effective way to address the needs of this growing, underserved population.
