Associations of DHEA(S) with negative and positive affect in people who smoke daily with elevated and low depression symptoms: A pilot laboratory study.

Background: Individuals with depression symptoms have a harder time quitting smoking. High negative affect and low positive affect are core depression symptoms and arise following cigarette abstinence. Investigating associations of biological markers with negative and positive affect may provide valuable information about factors relevant to smoking cessation in individuals with elevated depression symptoms.

Longitudinal associations between anxiety sensitivity and substance use in adolescents: Mediation by depressive affect.

Though anxiety sensitivity (AS)-fear of anxiety-related experiences-is primarily tied to anxiety vulnerability, AS has also been prospectively associated with general negative affect and depression. Furthermore, depression has been longitudinally associated with different forms of substance use, and some AS subfactors (e.g.

BDNF and stress/mood-related interactions on emotional disorder symptoms, executive functioning, and deliberate self-harm.

Some prior research has suggested that the brain-derived neurotrophic factor (BDNF) gene may amplify responses related to life stress (e.g., depression and anxiety) or associated with negative moods (e.

Cluster-b personality disorder traits and impulsivity: Indirect associations with alcohol use severity through positive alcohol expectancies.

Prior theory and research suggest that both Cluster-B personality pathology and trait impulsivity are indirectly associated with alcohol use through positive alcohol expectancies. Yet, no prior study has investigated whether features of each of the Cluster-B personality disorders (PDs) (i.e.

Drinking among college student athletes during the COVID-19 pandemic.

To investigate demographics, sport type, athletic identity, and COVID-19 sport season cancelation in relation to alcohol consumption among college student athletes shortly after the pandemic emerged. College student athletes recruited from U.S.

Effects of bodily arousal on desire to drink alcohol among trauma-exposed college students.

Introduction: Alcohol consumption on college campuses is a major public health concern. Extant literature has identified trauma exposure as a robust risk factor for problematic alcohol use in this at-risk population. However, the mechanisms underlying this association are less well-studied.

Anhedonia in tobacco withdrawal among African-American smokers.

Anhedonia-diminished interest and pleasure in response to rewards-may be a symptom of tobacco withdrawal that is understudied in priority populations. This experiment investigated the magnitude and correlates of various dimensions of anhedonia during tobacco withdrawal among African-American (AA) smokers-a population subject to health disparities. AA smokers ( = 607; ≥ 10 cigarettes/day, 37.

Affect and subjective cognitive functioning by depression symptom levels during naturalistic cigarette smoking in premenopausal females who smoke daily.

High negative affect, low positive affect, and low cognitive functioning are depression-related states that may be particularly relevant to females who smoke cigarettes and may be more prominent following overnight tobacco abstinence. This study aimed to assess relations between depression symptom levels and negative affect, positive affect, and subjective cognitive functioning in premenopausal females who smoke. Premenopausal females who smoke daily with low ( = 66) or elevated ( = 33) baseline depression symptoms completed subjective ratings of negative affect, positive affect, and cognitive functioning pre-first cigarette (i.

Associations of perceived drinking motives of parents and friends on adolescents' own drinking motives.

Adolescents form perceptions of why their parents and friends drink alcohol that may impact adolescents' own drinking motives. This study tested whether perceived drinking motives of parents and friends are associated with adolescents' own drinking motives. Participants included community-recruited adolescents 14-17 years ( = 105; 63.

Analgesic Effect of Alcohol Mediates the Association between Alcohol Intoxication and Deliberate Self-Harm.

We examined whether the analgesic effect of alcohol mediates the association between alcohol and deliberate self-harm (DSH) using data from a larger study on alcohol effects. Men ( = 106) and women ( = 104) low-risk alcohol drinkers (ages  = 26.00,  = 6.

Obsessive-compulsive symptoms and cigarette smoking: an initial cross-sectional test of mechanisms of co-occurrence.

Tobacco addiction and obsessive-compulsive symptoms (OCS; intrusive thoughts or impulses that cause distress and rituals) are both mediated by compulsivity and negative reinforcement. Little evidence exists to guide theory, research, treatment, and population-based prevention of this co-occurrence. We propose a conceptual model of OCS-smoking co-occurrence in which smokers with elevated OCS capitalize on smoking to assuage OCS.

Anxiety sensitivity in relation to cigarette smoking and other substance use in African American smokers.

Anxiety sensitivity (AS)-fearfulness of anxiety symptoms-has been implicated in the etiology of emotional disorders (e.g., depressive and anxiety disorders) and linked to cigarette smoking and other substance use (SU).

Subjective effects from the first cigarette of the day vary with precigarette affect in premenopausal female daily smokers.

The 1st cigarette of the day is strongly tied to tobacco dependence. However, prior research has not investigated whether within-subject (WS) day-to-day fluctuations in prefirst-cigarette affect are associated with the subjective effects from the 1st cigarette of the day or whether these associations differ by smokers' average prefirst-cigarette affect. In the current study, 85 premenopausal female daily smokers completed baseline measures and 35 days of ecological momentary assessment.

Relations Between Parental Distress Intolerance, Adolescent Motives for Cigarette Use, and Adolescent Cigarette Smoking Levels.

A relatively large body of evidence indicates that coping motives for cigarette smoking are associated with a number of problematic outcomes (e.g., greater smoking frequency) among adolescents.

Indirect Associations of Anxiety Sensitivity with Tobacco, Alcohol, and Other Drug Use Problems Through Emotional Disorder Symptoms in Adolescents.

Theoretically, anxiety sensitivity-fear of anxiety symptoms-enhances perception of and emotional reactivity to autonomic arousal and mental distress, thereby increasing negative affect and motivation to use substances for negative reinforcement. Because no prior study of adolescents has tested if anxiety sensitivity is indirectly associated with substance use problems through symptoms of emotional disorders (i.e.

Anxiety sensitivity components in relation to alcohol and cannabis use, motives, and problems in treatment-seeking cigarette smokers.

Anxiety sensitivity (AS)- fear of anxiety symptoms and their potential negative consequences-has been implicated in the development of substance use problems and motivation to use substances for coping with distress, though the AS components (physical, cognitive, and social concerns) have not been studied extensively in relation to alcohol- and cannabis-related variables. In a cross-sectional design, self-report measures of AS and alcohol and cannabis use, motives, and problems were administered to 364 treatment-seeking cigarette smokers with a history of alcohol and cannabis use. In both adjusted and unadjusted analyses, linear regression models indicated that AS cognitive concerns are related to cannabis-use conformity motives, alcohol-use coping motives, and alcohol problems; AS physical and cognitive concerns are related to greater cannabis problems specifically in males; and AS social concerns are associated with greater social, coping, enhancement, and conformity drinking motives.

Associations of anxiety sensitivity and emotional symptoms with the subjective effects of alcohol, cigarettes, and cannabis in adolescents.

Maladaptive emotional traits (anxiety sensitivity [AS], fear of anxiety-related sensations and consequences) and symptoms (major depressive disorder [MDD] and generalized anxiety disorder [GAD] symptoms) could play a role in altering sensitivity to the subjective effects of drugs of abuse in adolescents. Data were drawn from a longitudinal study of high school students in Los Angeles, CA, USA who completed surveys and reported past six-month use of alcohol (n=1054), cigarettes (n=297), or cannabis (n=706). At each of the four semi-annual waves during mid-adolescence (14-16years old), students reported positive and negative subjective drug effects experienced in the prior six-months.

Anhedonia and Abstinence as Predictors of the Subjective Pleasantness of Positive, Negative, and Smoking-Related Pictures.

Introduction: Anhedonia-diminished interest or pleasure in response to rewards-is a dimension implicated in several psychiatric disorders linked to smoking. This laboratory study sought to identify motivational mechanisms linking anhedonia and tobacco addiction by testing the hypothesis that anhedonia, abstinence, and their interaction would predict excesses and deficits in the perceived pleasantness of smoking-related and positive pictures, respectively. We assessed the pleasantness of negative pictures as a secondary outcome.

Negative Urgency Is Associated With Heightened Negative Affect and Urge During Tobacco Abstinence in Regular Smokers.

Objective: Negative urgency-the tendency to act rashly during negative affective states-is a risk factor for regular cigarette smoking. This human laboratory study tested a novel theoretical model of the underlying mechanisms linking negative urgency and smoking motivation, which purports that smokers with high negative urgency are at increased susceptibility to abstinence-induced increases in negative affect, which, in turn, provokes the urge to smoke to suppress negative affect.

Method: Smokers (N = 180, >10 cigarettes/day) attended a baseline session at which they completed self-report measures of negative urgency and other co-factors and subsequently attended two counterbalanced within-subject experimental sessions (i.

Transdiagnostic processes linking anxiety symptoms and substance use problems among adolescents.

Numerous anxiety syndromes co-occur with substance use problems in adolescents, though the mechanisms underlying these comorbidities are not well understood. There are 3 transdiagnostic processes-anxiety sensitivity (fear of anxiety-related sensations), distress tolerance (capacity to withstand emotional distress), and negative urgency (propensity to respond impulsively to negative emotion)-that have been implicated in various anxiety and substance use problems. To examine whether anxiety sensitivity, distress tolerance, and negative urgency statistically mediated relations between symptoms of 3 different anxiety disorders (social anxiety, generalized anxiety, and panic disorders) and alcohol and cannabis use problems, cross-sectional analysis of high school students in Los Angeles (N = 3002) was assessed via paper and pencil questionnaires.

Longitudinal Associations between Anhedonia and Internet-Related Addictive Behaviors in Emerging Adults.

Internet addiction (including online gaming) has been associated with depression. However, most prior research relating internet addiction symptomatology to depressive symptoms has been cross-sectional, conducted with children and adolescents, and only examined depressive symptoms as a broad construct. The purpose of the current study was to examine potential longitudinal associations between anhedonia (i.

Social Self-Control Is a Statistically Nonredundant Correlate of Adolescent Substance Use.

The social self-control scale (SSCS), which taps provocative behavior in social situations, was compared with five potentially overlapping measures (i.e., temperament-related impulsivity, psychomotor agitation-related self-control, perceived social competence, and rash action in response to negative and positive affectively charged states) as correlates of tobacco use and other drug use among a sample of 3,356 ninth-grade youth in Southern California high schools.

Asians compared to Whites show increased response to d-amphetamine on select subjective and cardiovascular measures.

Objective: Identifying factors that moderate subjective response to stimulants is important for understanding individuals at risk for abusing these drugs. Some research suggests that Asians may respond differently to stimulants than other races, but controlled human laboratory research of stimulant administration effects in Asians is scant.

Methods: In this double-blind counterbalanced within-subject study, healthy stimulant-naïve participants (N = 65; 55% Asian; 63% female; age 18-35) received a single dose of 20-mg oral d-amphetamine or placebo on separate days.

Anxiety sensitivity facets in relation to tobacco use, abstinence-related problems, and cognitions in treatment-seeking smokers.

Anxiety sensitivity (AS)--fear of anxiety-related experiences--has been implicated in smoking motivation and maintenance. In a cross-sectional design, we examined AS facets (physical, cognitive, and social concerns) in relation to tobacco use, abstinence-related problems, and cognitions in 473 treatment-seeking smokers. After controlling for sex, race, age, educational attainment, hypertension status, and neuroticism, linear regression models indicated that AS physical and cognitive concerns were associated with tobacco dependence severity (β=.
