BACKGROUND The aim of this study was to compare the cognitive performance of cocaine dependent individuals (CDI) with that of pathological gamblers (PG). Cocaine dependence and pathological gambling share neurobiological vulnerabilities related to addiction, but PG are relatively free of the toxic consequences, such that any additional deficits observed in(More)

We administered a multidimensional measure of trait impulsivity (the UPPS-P impulsivity scale; Cyders et al., 2007) to a nonclinical sample of 155 individuals and selected 32 participants at the two ends of the trait impulsivity continuum: high (HI, n = 15) and low (LI, n = 17) impulsive women. We further tested these extreme groups on neuropsychological(More)

Face-to-face interviews with 687 young regular cocaine users (aged 18–30 years) in three Spanish cities: Barcelona, Madrid and Seville. HRQL was measured using the Nottingham(More)
The objective of this study is to explore the stability of personality dimensions in a selection of psychoactive substance abuse patients during treatment in therapeutic communities. The baseline assessment was conducted 15 to 20 days from the start of therapeutic community treatment, and the second assessment was conducted 3 months after admission. The(More)
BACKGROUND Individuals with cocaine dependence and co-occurring personality disorders are more likely to have increased impulsivity, dysfunctional beliefs, executive dysfunction and brain structural abnormalities by virtue of the conjoint impact of both pathologies. METHODS We recruited 32 cocaine dependent patients with comorbid Cluster B personality(More)
BACKGROUND The treatment of cocaine-dependent individuals (CDI) is substantially challenged by high drop-out rates, raising questions regarding contributing factors. Recently, a number of studies have highlighted the potential of greater focus on the clinical significance of neurocognitive impairments in treatment-seeking cocaine users. In the present(More)
Rave parties are characterized by high levels of drug use and polysubstance-using patterns that may be especially harmful for psychological and neuropsychological functioning. The aim of this study was to conduct a comprehensive assessment of different aspects of impulsivity and executive functions in a sample of polysubstance-using rave attenders. We(More)
BACKGROUND We aimed to explore the association between baseline executive functioning and treatment outcome in Therapeutic Communities (TCs). METHODS We used a longitudinal descriptive design: a baseline neuropsychological assessment was performed within the first 30 days of treatment in TCs. Once participants finished or abandoned treatment, the(More)
BACKGROUND Cocaine addiction and pathological gambling are commonly associated with steeper (impulsive) discounting of delayed rewards, which promotes ongoing drug and gambling behaviors. However, it is yet unclear whether impulsive delay discounting is a stable trait in cocaine and gambling disorders during abstinence, and whether it is significantly(More)
