Interaction effect of contingency management and sex on delay-discounting changes among treatment-seeking smokers.

Despite the potential influence of sex on delay-discounting rates, there is no previous evidence with regard to the effect of this variable on the clinical interventions aimed at modifying delay-discounting rates. This study assessed the effect of sex on the association between the type of treatment received (either cognitive-behavioral treatment [CBT] alone or combined with contingency management [CM + CBT]) and delay-discounting changes at end of treatment and 6-month follow-up. This aim was addressed after controlling for the influence of baseline delay discounting.

Spanish adaptation and validation of the Barratt Impulsiveness Scale for early adolescents (BIS-11-A).

Impulsivity has been associated with several psychiatric disorders such as substance abuse. The Barratt Impulsiveness Scale (BIS-11) is one of the most commonly administered self-reports for the assessment of impulsiveness in both research and clinical settings. There is a version for adolescents called BIS-11-A, which has not been yet properly adapted to Spanish population.

Contingency management for cigarette smokers with depressive symptoms.

Despite depressive symptoms being very common among smokers from the general population, few studies have examined the effects of depressive symptoms on smoking treatment outcomes, and even less research has been carried out in the context of contingency management (CM). The authors conducted a secondary analysis to assess the interrelation between treatment condition, depressive symptoms and treatment outcomes among treatment-seeking smokers. The sample was made up of 147 treatment-seeking smokers who were randomly allocated 2 treatment conditions: cognitive behavioral treatment (CBT; n = 74), or CBT + CM (n = 73).

Contingency management for substance use disorders in Spain: Implications for research and practice.

Objective: We provide a narrative review of published studies evaluating voucher-based contingency management (CM) treatment for cocaine, nicotine and cannabis use disorders in Spain and discuss the concerns and future challenges.

Method: Published studies between 2008 and 2015 that evaluated the impact of incentives for SUD in Spain and included an appropriate control or comparison condition were identified and reviewed.

Results: Adding voucher-based CM to standard treatments obtained better treatment retention and cocaine abstinence than standard care alone.

The association of both self-reported and behavioral impulsivity with the annual prevalence of substance use among early adolescents.

Background: In relation to substance use, Spanish adolescents aged 12 to 14 can be largely classified in four groups, from highest to lowest prevalence: (a) No substance use, (b) Only alcohol use, (c) Alcohol and tobacco use, and (d) Alcohol, tobacco and cannabis use. The aim of the present study is to analyze the possible relationship between impulsivity and the substance-use group to which the young person belongs

Methods: One thousand three hundred and forty-eight adolescents aged 12 to 14 in northern and eastern Spain reported their drug use, completed impulsivity self-reports (BIS-11-A and ImpSS) and performed behavioral tasks (Stroop Test and Delay Discounting).

Results: Results from both measurement approaches were related to early drug use.

Individual variables related to craving reduction in cue exposure treatment.

Introduction: Although extensive research has demonstrated that cigarette craving can be effectively attenuated, very few studies have explored associations between individual variables and craving reduction. This study explored whether individual characteristics predict craving decreases during virtual reality cue exposure treatment (VR-CET).

Method: Participants were 41 treatment-seeking smokers (73% women) with a mean age of 39.

Interaction of depressive symptoms and smoking abstinence on delay discounting rates.

Delay discounting and depressive symptomatology have strong connections with smoking. However, few studies have examined interactions across delay discounting, depressive symptoms, and smoking status. The primary goal of this secondary analysis was to assess the interrelations across these 3 variables among treatment-seeking smokers.

Toward a comprehensive developmental model of smoking initiation and nicotine dependence.

Background: This study aims to identify predictors of smoking initiation and nicotine dependence (ND) to develop a comprehensive risk-factor model based on Kendler's development model for major depression.

Methods: Data were drawn from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), Wave 2 (n=34,653). Risk factors were divided into five developmental tiers according to Kendler's model (childhood, early adolescence, late adolescence, adulthood, past-year).

Probability and predictors of the cannabis gateway effect: a national study.

Background: While several studies have shown a high association between cannabis use and use of other illicit drugs, the predictors of progression from cannabis to other illicit drugs remain largely unknown. This study aims to estimate the cumulative probability of progression to illicit drug use among individuals with lifetime history of cannabis use, and to identify predictors of progression from cannabis use to other illicit drugs use.

Methods: Analyses were conducted on the sub-sample of participants in Wave 1 of the National Epidemiological Survey on Alcohol and Related Conditions (NESARC) who started cannabis use before using any other drug (n=6624).

Effects of systematic cue exposure through virtual reality on cigarette craving.

Introduction: Cigarette cravings have been associated with less successful attempts to quit smoking and a greater likelihood of relapse after smoking cessation. Background craving refers to a relatively steady and continuous experience of craving, while cue-induced craving refers to phases of intense craving triggered by cues associated with smoking. Cue exposure treatment (CET) involves repeated exposure to stimuli associated with substance use in order to reduce craving responses.

Predictors of quit attempts and successful quit attempts among individuals with alcohol use disorders in a nationally representative sample.

Background: This study sought to identify predictors of attempting to quit and of successfully quitting alcohol abuse or dependence in the general population.

Methods: Data were drawn from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC).

Results: Approximately 10% of individuals with alcohol abuse and 18% of those with dependence attempted to quit over the three year follow-up period.

Contingency management for smoking cessation among treatment-seeking patients in a community setting.

Background: Contingency management (CM) is an efficacious intervention for reducing cigarette smoking. However, CM is rarely adopted as a smoking cessation treatment in the community. This study analyzed the effectiveness of a CM procedure in combination with a cognitive-behavioral treatment (CBT) for smoking cessation among treatment-seeking patients from the general population.

Decreased delay discounting in former cigarette smokers at one year after treatment.

Current cigarette smokers exhibit greater delay discounting relative to ex-smokers. However, few studies have assessed longitudinal changes in delay discounting and cigarette smoking. The purpose of this study was to assess changes in delay discounting of hypothetical monetary rewards and smoking among treatment-seeking smokers (N=80) at baseline, after 6 weeks of behavioral treatment, and at 12-month follow-up.

Self-change among Spanish speakers with alcohol and drug use disorders in Spain and the United States.

Objective: Few cross-cultural studies have investigated the self-change process with substance abusers. This study examined commonalities and differences related to the self-change process with Spanish speaking self-changers in Spain and the United States (U.S.

Contingency management improves outcomes in cocaine-dependent outpatients with depressive symptoms.

Despite depressive symptoms being very common among patients seeking treatment for cocaine dependence, few studies have examined the effects of depressive symptoms on cocaine outpatient treatment outcomes, and there is even less research in the context of Contingency Management (CM). The purpose of this study was to assess the main and interactive effects of co-occurring depressive symptoms on CM outcomes. Cocaine-dependent individuals (N = 108) were randomized to Community Reinforcement Approach (CRA) or CRA plus CM in two outpatient community clinical settings.

A systematic assessment of delay discounting in relation to cocaine and nicotine dependence.

Delay discounting is a measure of impulsivity describing how a reinforcer loses value as the delay to its receipt increases. Greater delay discounting is reliably observed among those with different substance use disorders (SUDs) compared to the general population. Nevertheless, the relation between delay discounting and the type and number of substances used remains unclear.

Peak provoked craving after smoking cessation.

Peak provoked craving (PPC) is an alternative approach to cue-induced craving that focuses on the highest craving level experienced during the exposure to drug-related cues. The main objective of this study was to assess the effect of abstinence on PPC in smokers and to determine whether PPC is altered by continuous abstinence. Results showed reductions on PPC levels only 24 hours after achieving abstinence and craving levels remain significantly lower after 7 days of abstinence.

Smoking a virtual cigarette increases craving among smokers.

Previous studies have shown the efficacy of virtual reality (VR) environments that reproduce smoking-related stimuli for increasing self-reported craving and psychophysiological reactivity in smokers. However, no study to date has attempted to simulate smoking behavior itself by means of VR technology. The aim of this study was to assess the effect of smoking a virtual cigarette on self-reported craving levels and heart rate (HR) in a sample of smokers.

Probability and predictors of relapse to smoking: results of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC).

Background: The goal of this study was to estimate rates of relapse to smoking in the community and to identify predictors of relapse.

Methods: Data were drawn from the Waves 1 and 2 of the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC). Logistic regression analyses were used to estimate the probability of relapse at Wave 2 among individuals who were abstinent at Wave 1 given length of abstinence as well as the presence of several sociodemographic, psychopathologic and substance use-related variables at Wave 1.

Gender differences in early alcohol and tobacco use as a risk factor in Spanish adolescents.

The sample is made up of 1,190 adolescents (52.8% boys; mean age = 16.81) from 37 random schools in the urban and rural areas of Asturias (northern Spain).

Probability and predictors of cannabis use disorders relapse: results of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC).

Background: This study aims to estimate the odds and predictors of Cannabis Use Disorders (CUD) relapse among individuals in remission.

Methods: Analyses were done on the subsample of individuals with lifetime history of a CUD (abuse or dependence) who were in full remission at baseline (Wave 1) of the National Epidemiological Survey of Alcohol and Related Conditions (NESARC) (n=2350). Univariate logistic regression models and hierarchical logistic regression model were implemented to estimate odds of relapse and identify predictors of relapse at 3 years follow up (Wave 2).

Predictors of quit attempts and successful quit attempts in a nationally representative sample of smokers.

Although most current smokers report that they would like to quit, most quit attempts fail suggesting that predictors of quitting attempts may differ from those of successful attempts. We examined sociodemographic and clinical predictors of quit attempts and successful quit attempts in a nationally representative sample of US adults. Data was collected in 2001-2002 (Wave 1) and 2004-2005 (Wave 2).

Contingency management is effective across cocaine-dependent outpatients with different socioeconomic status.

Contingency management (CM) has demonstrated its efficacy for treating cocaine dependence, but there is still some controversy with regard to its dissemination. Understanding how individual differences affect CM outcomes is important for detecting barriers to its dissemination. The aim of this study is to examine the impact of socioeconomic variables in cocaine-dependent outpatients on the effectiveness of CM in a community setting.
