Psychology of Addictive Behaviors

OBJECTIVE: Subjective intoxication (SI) when drinking may serve as an internal barometer of whether to continue drinking or engage in potentially unsafe behavior. Mobile assessments offer the potential to use SI as a prospective risk indicator during drinking episodes; little evidence exists for the validity of real-time SI measures. We test the correspondence of SI with estimated blood alcohol concentration and transdermal alcohol concentration (TAC) in young adults' natural settings...

OBJECTIVE: Cannabis use is increasing among college students and commonly co-occurs with anxiety symptoms in this age group. Interventions that reduce anxiety may also reduce cannabis use. Behavioral economic theory suggests that substance use reductions are most likely when there is an increase in substance-free reinforcement. This randomized pilot trial evaluated the efficacy of a brief motivational intervention (BMI) for cannabis supplemented by either a substance-free activity session (SFAS) or a relaxation training (RT) session for reducing cannabis use, problems, craving, and anxiety symptoms...

OBJECTIVE: Behavioral economic theory suggests that alcohol risk is related to elevated alcohol reinforcing efficacy (demand) combined with diminished availability of reinforcing substance-free activities, but little research has examined these reward-related processes at the daily level in association with comorbid conditions that might influence behavioral patterns and reward. Young people with attention-deficit/hyperactivity disorder (ADHD) report high levels of risky drinking, and this risk may be due in part to elevated demand for alcohol and diminished engagement in enjoyable and valued substance-free activities...

OBJECTIVE: In June 2022, the U.S. Supreme Court released a landmark decision in which they held that the right to abortion is not protected by the U.S. Constitution, ending almost 50 years of federally legal abortion in the United States. Because prior research demonstrates linkages between reproductive health and substance use at multiple socioecological levels, in this special section, we present studies that take a broad scope to understanding how addictive behaviors and reproduction-related behaviors, options, and access to care interrelate across a variety of contexts...

OBJECTIVE: Exercise is increasingly used as adjunct treatment for alcohol use disorder (AUD). Evidence suggests that moderate-to-high-intensity exercise can ameliorate cravings. We explored the potential mediating effects of changes in mood states in the relationship between exercise intensity and alcohol cravings. METHOD: Secondary analyses of a nested single-arm trial within a randomized controlled trial (FitForChange). In total, 117 sedentary adults (68.4% female, M = 52 ± 12 years) with clinician diagnosed (Diagnostic and Statistical Manual of Mental Disorders, fifth edition ) AUD and indications of craving (Desire for Alcohol Questionnaire) completed a 12-min submaximal cardiorespiratory fitness test on a cycle ergometer...

OBJECTIVE: Theory and evidence indicate that affirming the value of the self before exposure to a threatening message fosters more open-minded appraisal of message content. We predicted that college students mandated to a computer-delivered personalized feedback intervention (PFI) and who engaged in a self-affirmation (SA) exercise would demonstrate reduce drinking and consequences relative to those who received an attention control. METHOD: Participants were 484 undergraduates (age 18-24, 56% male, 78% White) mandated to participate in an alcohol intervention following a first-time alcohol policy violation...

OBJECTIVE: Women in academia publish fewer papers and receive fewer citations than men. These gender gaps likely reflect systemic biases operating over several levels, from journal editorial policies to academic career progression. This study sought to characterize gender gaps for publications and citations in the field of gambling studies. METHOD: An automated gender inference procedure classified authors' binarized gender from their first names. Gender gaps were computed for publications and citations of papers in gambling studies, using the wider field of addiction science as a benchmark...

OBJECTIVE: It is hypothesized that alcohol use is reinforcing when used as a strategy to cope with negative affect. Although the evidence for this hypothesis in observational data is weak, some experimental evidence suggests that the behavioral economic demand for alcohol increases immediately following a negative emotional event. We hypothesized that people show a higher demand for alcohol following negative (vs. neutral) mood inductions and that this effect is stronger in people who report heavier drinking compared to people who report lighter drinking as well as stronger on days characterized by higher coping motives and negative urgency...

OBJECTIVE: Emotions play a critical role in health risk behaviors, including substance use. However, current research often focuses exclusively on average levels of positive and negative affect, neglecting the complexity of daily emotional patterns. By capturing multiple dimensions of affect, including arousal and discrete states, we can improve our understanding of proximal predictors of substance use. The present study demonstrates the utility of a novel methodological approach for assessing affect patterns in daily life in relation to alcohol and cannabis use...

OBJECTIVE: The Diagnostic and Statistical Manual of Mental Disorders, fifth edition conceptualizes alcohol use disorder (AUD) as a single continuum with indicators to denote the level of severity along this spectrum with the presence of 2-3, 4-5, or 6 + symptoms indicating mild, moderate, and severe AUD, respectively. However, despite the labels of these indicators, it remains unclear how individuals compare across these indicators, both in terms of AUD severity, but also risk for other related problems (e...

OBJECTIVE: Researchers and theorists studying intergroup relations have been interested in the impact of alcohol on interracial responding. Theories predict that alcohol will exacerbate expressions of racial bias by increasing reliance on stereotypes and/or by decreasing controlled processing and self-monitoring. Prior studies testing these theories have often examined alcohol's effects on implicit (i.e., indirect) measures of racial bias with inconsistent results. However, previous research in this area has suffered from several methodological limitations, including small sample sizes and doses of alcohol that may have been too low to induce substantial intoxication...

OBJECTIVE: Affective experiences are associated with smoking urges and behavior. Few studies have examined the temporal nature of these associations within a day, such as whether positive and negative affect in the morning are associated with smoking urges and behavior later in the day. METHOD: Participants ( N = 63; M Age = 50 years, 48% female; 60% White) were randomized into one of three smoking cessation interventions and answered up to five daily ecological momentary assessments for 28 days during a quit attempt ( M = 21...

OBJECTIVE: Chronic musculoskeletal pain (CMP) is prevalent, burdensome, and associated with an increased risk for opioid use disorder. Evidence suggests that perceived racial/ethnic discrimination is associated with problematic substance use among Black individuals, but studies have not focused on problematic opioid use among Black individuals with CMP specifically or explored the contribution of perceived discrimination, pain intensity, and pain-relevant psychological factors to this association...

OBJECTIVE: The Alcohol Addiction Research Domain Criteria (AARDoC) is an organizational framework for assessing heterogeneity in addictive disorders organized across the addiction cycle domains of incentive salience, negative emotionality, and executive functioning and may have benefits for precision medicine. Recent work found pretreatment self-report items mapped onto the addiction cycle domains and predicted 1- and 3-year alcohol use disorder treatment outcomes. Given the potential utility of the addiction cycle domains for predicting relevant treatment outcomes, this study sought to evaluate the longitudinal measurement invariance of the domains...

OBJECTIVE: Compared with men, women are disproportionately affected by alcohol, including greater risks of behavioral impairment and relapse from abstinence-based treatments. One potential mechanism underlying this disparity is ovarian hormone fluctuations across menstrual cycle phases, particularly estradiol (E2). Preclinical and clinical studies have shown that E2 levels positively correlate with alcohol consumption, suggesting E2 modulates drinking. Rewarding properties of alcohol are thought to mediate this relationship...

OBJECTIVE: Sports betting accounts for the greatest proportion of online gambling behavior globally and has been linked to various harms. Few studies have examined the average sports bettor profile using stratified samples of adults who gamble regularly. The present study builds upon existing research on the demographic variables of sports bettors and provides an in-depth examination of the clinical and gambling-related factors associated with sports betting. METHOD: Participants (N = 10,039; 53...

OBJECTIVE: Prevalence rates of cannabis use and PTSD vary, with men reporting greater cannabis use than females, females reporting higher rates of PTSD than males, and race and ethnic minority persons reporting higher rates of both cannabis and PTSD compared to non-Hispanic White individuals. This study extends our understanding of directional associations between cannabis use and PTSD from early to late young adulthood (18-26 years old) using two theoretical models: symptom-driven pathway and substance-induced pathway...

OBJECTIVE: Lower sensitivity to the acute effects of alcohol is known to confer risk for the development of alcohol use disorder. Alcohol sensitivity, or level of response to alcohol's subjective effects, is heritable but also can change as a result of persistent alcohol exposure (i.e., acquired tolerance). Here, we examined how changes over time in four indices of alcohol involvement affected scores on two validated, retrospective self-report measures of alcohol response-the Self-Rating of the Effects of Alcohol (SRE) form and the Alcohol Sensitivity Questionnaire (ASQ)-in a sample of emerging adult drinkers...

OBJECTIVE: Posttraumatic stress disorder (PTSD) symptoms and alcohol use commonly co-occur and present a prevalent clinical comorbidity. The self-medication/coping model has been applied most consistently to understand the PTSD-alcohol use association. However, there is a relative paucity of self-report measures designed to assess motivations for alcohol use, specifically for coping with PTSD symptoms. The goals of the present study were to develop and validate a measure that assesses the use of alcohol to cope with specific facets of PTSD symptomatology across two independent samples...

OBJECTIVE: Sexually aggressive behavior (SAB), risky sexual behavior (RSB), and heavy episodic drinking (HED) are serious behavioral health problems among college men. The present study substantially revises and validates protective behavioral strategies (PBS) measures in the SAB and RSB domains; evaluates the relations among PBS usage in the SAB, RSB, and HED domains; and determines whether college men with SAB, RSB, or HED histories report lower PBS usage. METHOD: College students who identified as men ( n = 1,121) completed measures of PBS, SAB, RSB, HED, rape-supportive attitudes, sociosexuality, and bar/party attendance...
