BACKGROUND: Self-administration is a hallmark of all addictive drugs, including alcohol. Human laboratory models of alcohol self-administration have characterized alcohol-seeking behavior, and served as surrogate measures of the effectiveness of pharmacotherapies for alcohol use disorders. Intravenous alcohol self-administration (IV-ASA) is a novel method that assess alcohol exposure driven primarily by the pharmacological response to alcohol, and may have utility in characterizing unique behavioral and personality correlates of alcohol-seeking and consumption...

Alcohol-related blackouts are common among college student drinkers. The present study extends prior work by examining latent growth classes of blackouts and several predictors of class membership. Participants (N = 709 college drinkers) completed a baseline survey at college entry and biweekly online assessments throughout freshman and sophomore years. Results revealed 5 latent growth class trajectories, reflecting varying experiences of blackouts at the beginning of college and differential change in blackouts over time...

Objective: Alcohol use disorders (AUDs) are prevalent in the military and are a major public health concern. Although efficacious AUD interventions exist, few service members seek treatment. Army-specific barriers to AUD treatment include treatment being recorded on health records, command being notified of participation, and perceptions that seeking treatment would interfere with promotion or retention in the military. Evaluate a telephone delivered motivational interviewing plus feedback (MIF) intervention designed to attract self-referral and reduce substance use from active-duty military with untreated AUD...

BACKGROUND: Only one laboratory study has examined the relation between stress and alcohol use in an ecologically valid drinking context. In that prior study, drinking was measured after the stressful situation. OBJECTIVE: To examine the effect of an anticipatory stressor, and trait social anxiety on "alcohol" consumption in a bar laboratory. METHODS: College students aged 18 and older (N = 127) in same-sex groups of two or three participants took part in a study that ostensibly examined alcohol's effect on language fluency...

BACKGROUND: Substance use disorders (SUDs) represent a great barrier to functional recovery for individuals with schizophrenia. It is important to use research on treatment of SUDs in schizophrenia to guide treatment recommendations and program planning. OBJECTIVES: We review studies of pharmacological and psychosocial interventions to treat SUDs in individuals with schizophrenia. METHODS: The criteria used to select studies for inclusion are (1) the percentage of the sample with a schizophrenia spectrum diagnosis is at least 25%; (2) participants have a comorbid SUD or problem use of substances; (3) an intervention for SUD is provided; (4) a substance use-related outcome is measured; and (5) the study design enabled examination of pre-post outcome measures including open label trials, nonrandomized evaluations (quasi-experimental designs, nonrandom assignment to groups), or randomized controlled trials...

Young men who have sex with men (YMSM) report higher rates of substance use than their heterosexual peers and minority stress has been posited as a risk factor for substance use. The associations between specific types of minority stress and substance use have been inconsistent throughout the literature and few studies have examined mechanisms underlying these associations. Drawing on minority stress theory and the motivational model of alcohol use, we propose that one mechanism underlying these associations may be people's motivations for using substances, including using substances to cope with negative emotions and to enhance pleasure...

PURPOSE: The present work examined the influence of drinking motives on hookah use frequency among individuals reporting both alcohol and hookah use (multi-substance users). Despite growing documentation of cross-substance effects between motives and substance use, limited research has examined these relationships specifically with respect to hookah use. METHODS: Participants were 134 (75.37% female) hookah and alcohol users, aged 18-47 years (M = 22.17, SD = 3...

With its ease of availability during adolescence, sweetened ethanol ('alcopops') is consumed within many contexts. We asked here whether genetically based differences in social motivation are associated with how the adolescent social environment impacts voluntary ethanol intake. Mice with previously described differences in sociability (BALB/cJ, C57BL/6J, FVB/NJ and MSM/MsJ strains) were weaned into isolation or same-sex pairs (postnatal day 21), and then given continuous access to two fluids on postnatal days 34-45: One containing water and the other containing a ascending series of saccharin-sweetened ethanol (3-to-6-to-10%)...

Fluid ingestion is necessary for life, and thirst sensations are a prime motivator to drink. There is evidence of the influence of oropharyngeal stimulation on thirst and water intake in both animals and humans, but how those oral sensory cues impact thirst and ultimately the amount of liquid ingested is not well understood. We investigated which sensory trait(s) of a beverage influence the thirst quenching efficacy of ingested liquids and the perceived amount ingested. We deprived healthy individuals of liquid and food overnight (> 12 hours) to make them thirsty...

Rhesus macaques are an important model in behavioral neuroscience due to their advanced cognitive abilities. To motivate animals to engage in complex tasks, fluid rewards, in conjunction with fluid control protocols, are often used. The impact of these protocols on animal welfare is controversial. We compared two fluid control protocols against a protocol providing free access to water and evaluated the impacts on physiological states of hydration, behavioral measures of welfare, and scientific output. Blood physiology did not significantly differ between any of the protocols, and urine measures were indicative of well functioning, healthy kidneys...

BACKGROUND: Childhood obesity prevention is a pressing issue. Understanding the relationships among eating and physical activity behaviors and potential psychosocial determinants of behavior will help us design more effective interventions. This study aimed to examine such relationships in a large sample of urban elementary school children. METHODS: Fifth grade students in 20 recruited New York City public schools completed a validated questionnaire on six "do more" (fruits and vegetables and physical activity) and "do less" (sweetened beverages, processed packaged snacks, fast food and sedentary behavior) energy balance related behaviors (EBRBs) and psychosocial determinants of behavior from social cognitive and self-determination theories...

Heavy drinking by college students is exceedingly harmful to the individuals and to the overall college environment. Current interventions to reduce drinking and negative consequences are infrequently utilized. This randomized clinical trial examined an alternative approach that sought to increase exercise behavior, a substance free activity, in sedentary heavy drinking college students. Participants (N = 70) were randomized to an 8-week exercise intervention: (a) motivational interviewing plus weekly exercise contracting (MI + EC) or (b) motivational interviewing and weekly contingency management for exercise (MI + CM)...

BACKGROUND: Understanding the potential psychosocial mechanisms that explain (i.e., mediate) the associations between depressive symptoms and alcohol-related problems can improve interventions targeting college students. OBJECTIVES: The current research examined four distinct facets of rumination (e.g., problem-focused thoughts, counterfactual thinking, repetitive thoughts, and anticipatory thoughts) and drinking to cope motives as potential explanatory mechanisms by which depressive symptoms are associated with increased alcohol-related problems...

Social norms affect human behavior, and underage drinking is no exception. Using the theory of normative social behavior, this study tested the proposition that the association between perceptions about the prevalence of drinking (descriptive norms) and underage drinking is strengthened when perceived pressures to conform (injunctive norms) and beliefs about the benefits of drinking (outcome expectations) are high. This proposition was tested on a nationally representative sample of underage drinkers ages 13-20 (N = 1,031) in relation to their alcohol consumption, expanding on research with college-age youth...

INTRODUCTION: Combat veterans are at increased risk for PTSD and alcohol misuse, and expectancies and motives for drinking may help explain the link between these comorbid issues. This investigation explored the relationships between PTSD symptoms, PTSD-related alcohol expectancies, motives for drinking, and alcohol consumption/misuse. METHOD: 67 veterans of Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND) participated in this project...

Addiction to alcohol remains a major social and economic problem, in part because of the high motivation for alcohol that humans exhibit and the hazardous binge intake this promotes. Orexin-1-type receptors (OX1Rs) promote reward intake under conditions of strong drives for reward, including excessive alcohol intake. While systemic modulation of OX1Rs can alter alcohol drinking, the brain regions that mediate this OX1R enhancement of excessive drinking remain unknown. Given the importance of the nucleus accumbens (NAc) and anterior insular cortex (aINS) in driving many addictive behaviors, including OX1Rs within these regions, we examined the importance of OX1Rs in these regions on excessive alcohol drinking in C57BL/6 mice during limited-access alcohol drinking in the dark cycle...

BACKGROUND: When sober, problematic drinkers display exaggerated reactivity to threats that are uncertain (U-threat). Since this aversive affective state can be alleviated via acute alcohol intoxication, it has been posited that individuals who exhibit heightened reactivity to U-threat at baseline are motivated to use alcohol as a means of avoidance-based coping, setting the stage for excessive drinking. To date, however, no study has attempted to characterize the dispositional nature of exaggerated reactivity to U-threat and test whether it is a vulnerability factor or exclusively a disease marker of problematic alcohol use...

What can be done to reduce unhealthy eating among adolescents? It was hypothesized that aligning healthy eating with important and widely shared adolescent values would produce the needed motivation. A double-blind, randomized, placebo-controlled experiment with eighth graders (total n = 536) evaluated the impact of a treatment that framed healthy eating as consistent with the adolescent values of autonomy from adult control and the pursuit of social justice. Healthy eating was suggested as a way to take a stand against manipulative and unfair practices of the food industry, such as engineering junk food to make it addictive and marketing it to young children...

BACKGROUND: Informed by inconsistent findings regarding the association between injunctive norms (IN) and drinking behaviors, the current study developed a new measure of IN, the Injunctive Norms Drinking and Abstaining Behaviors Questionnaire (IN-DABQ). This measure addressed several psychometric weaknesses of prior assessment of this construct, specifically, reliance on single-item measures, and assessment of a limited range of drinking behaviors. The new measure also assessed norms for reasons for abstaining from drinking as college students often have simultaneous motives to use and inhibit their drug use...

OBJECTIVE: Depressive symptoms and drinking to cope with negative affect increase the likelihood for drinking-related negative consequences among college students. However, less is known about their influence on the naturalistic trajectories of alcohol-related consequences. In the current study, we examined how positive and negative drinking-related consequences changed as a function of depressive symptoms and drinking motives (coping, conformity, social, enhancement). METHOD: Participants (N=652; 58% female) were college student drinkers assessed biweekly during the first two years of college...
