Psychology of Addictive Behaviors

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...

OBJECTIVE: Early exposure to drug use and sexual abuse may contribute to later substance use, causing downstream effects on sexual and pregnancy-related behaviors. We applied the life course perspective to qualitative interview findings conducted with women with criminal legal involvement to explore connections between participants' early exposure to drugs and childhood sexual abuse with subsequent engagement with substance use and sexual and reproductive behaviors. METHOD: We analyzed semistructured interviews with 33 racially diverse women with criminal legal involvement, Ages 18-65, who were recruited from a community organization in the Midwestern United States to explore their experiences and perspectives on factors that influenced their substance use and reproductive health behaviors...

OBJECTIVE: Remission from problem gambling (PG) continues to be a priority of clinicians and researchers. Data from cross-sectional studies indicate that some correlates are more predictive of PG, and existing longitudinal studies have exclusively examined risk factors that predict emergence of PG. This study's objective is to fill in the remaining pieces of the puzzle by identifying factors that might facilitate remission from PG. METHOD: A stratified sample of 10,199 Canadian adult gamblers were recruited from an online panel...

OBJECTIVE: The purpose of this research was to assess factors (i.e., emotion regulation, impulsivity) that motivate in-play sports betting. Specifically, we examined whether individuals report increased excitement after placing an in-play bet and whether trait negative and positive urgency moderate the effect of emotion regulation motives on in-play betting frequency. METHOD: Three cross-sectional studies were conducted, each following a major sporting event: Superbowl LVI (56) (Study 1), March Madness Final (Study 2), and Union of European Football Associations Champions League Final (Study 3)...

OBJECTIVE: Land-based gambling venues remain predominantly cash-based despite broader consumer trends toward digital payments. Little prior literature directly investigates the role of payment methods in gambling; however, digital payment systems offer a key intervention point for gambling harm minimization. This study explores the perspectives of electronic gaming machine (EGM) gamblers regarding the concept of cashless gambling-the ability to gamble without using physical currency. METHOD: Twenty-six Australian EGM gamblers (10 females, 16 males; aged 24-76 years) participated in four online focus group discussions...

OBJECTIVE: Despite rates of alcohol misuse being higher among emerging adults experiencing homelessness compared to those who are stably housed, there are few brief evidence-based risk reduction programs for this population that focus on alcohol use and assess outcomes for more than 1 year. This study examines alcohol outcomes from a 24-month evaluation of AWARE, a brief motivational interviewing-based group risk reduction intervention for emerging adults experiencing homelessness. METHOD: In a cluster randomized crossover trial, 18- to 25- year-olds received AWARE ( n = 132) or standard care ( n = 144) at one of three drop-in centers serving young people experiencing homelessness in Los Angeles County...

OBJECTIVE: A severe and long-term alcohol use can have adverse effects on lower limb function. Over time, some individuals may develop gait ataxia, which refers to the impairment of controlled lower body movements that are important for walking and maintaining proper gait. Gait ataxia is well-documented in patients who have been diagnosed with alcohol-related Wernicke-Korsakoff syndrome (WKS); however, less is known on how common ataxia is among patients with alcohol use disorder (AUD) without WKS...

OBJECTIVE: The timeline follow-back interview is a common method of collecting daily cigarette consumption (cigarettes per day [CPD]) in smoking research. However, it may be subject to recall bias due to its reliance on retrospective reports. The increasing ownership of smartphones allows researchers to administer app-based digital diaries (DD) to collect CPD, which is expected to have less recall bias. Several studies have compared these two methods and found a noticeable discrepancy between them...

OBJECTIVE: From 2022, the International Classification of Diseases, eleventh edition (ICD-11) includes the first mental disorder based on digital technology, "gaming disorder," which was previously suggested as a condition for further examination in the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5). In this cross-sectional study, we provide the first large-scale network analysis of various symptom structures for these constructs to understand the complex interconnections between their proposed symptoms...

OBJECTIVE: Cisgender men's condom use resistance (CUR), deliberate attempts to avoid using a condom with a partner who wishes to use one, may include coercive strategies, such as deception and force, and places their partners at risk for unintended pregnancy and sexually transitted infections (STIs). This investigation used an alcohol administration design to examine one distal (history of unintended partner pregnancy) and two proximal (acute alcohol intoxication, condom use rationale) contributors to men's intentions to engage in coercive CUR...

OBJECTIVE: The main reasons women in the general population seek abortion are financial, timing, and partner-related reasons. While women with opioid use disorder (OUD) appear to use abortion services more than women in the general population, reasons for abortion in this group have not been examined to our knowledge. METHOD: Female patients aged 18-50 years in OUD treatment at 22 randomly selected facilities in Michigan were surveyed. The survey included items assessing reproductive health history...

OBJECTIVE: The Supreme Court of the United States' decision in Dobbs v. Jackson Women's Health Organization in June 2022 overturned Roe v. Wade and ended federal protection of abortion rights. Given the drastic policy changes as a result of the ruling and high exposure to media related to abortion, women opposed to the decision may have experienced distress, which could trigger maladaptive coping strategies, such as alcohol use. The present research examined how consuming abortion-related media in the weeks following the Dobbs decision impacted alcohol use intentions among women of reproductive age residing in the 13 "trigger law" states that immediately restricted abortion access...

OBJECTIVE: Despite the widespread use of harm prevention messages on gambling advertising, it is unclear whether such messages achieve their goal of encouraging safer gambling behavior and preventing gambling harms. The current research therefore investigates whether and how existing harm prevention messages implemented on gambling advertisements in Belgium and the Netherlands affect consumers' gambling-related beliefs and intentions. METHOD: Two experimental studies (Nexperiment 1 = 169; Nexperiment 2 = 212) investigate (a) the influence of message prominence and (b) the impact of message framing by comparing the effectiveness of the message "Gamble in moderation" with different types of Flemish and Dutch harm prevention messages (that are currently used in Belgium and the Netherlands) on people's gambling-related beliefs and intentions...

OBJECTIVE: People with substance use disorders (SUDs) are faced with pervasive stigma. Education-based interventions tend to emphasize biological causes of dependency; however, health care professionals still stigmatize people who use substances despite being more knowledgeable about biological causes. There may be an important moderating role of personal contact since health care professionals may treat people in the throes of dependency. METHOD: We tested how substance use stigma may be explained by causal attributions, working in health care, and personal contact...

OBJECTIVE: The American College of Obstetricians and Gynecologists (ACOG) recommends providers screen their prenatal patients for 11 psychosocial issues because they affect patient mental and physical well-being. The prevalence and co-occurrence of these issues have rarely been compared among pregnant women who do and do not report recent illicit substance use. METHOD: Seven psychosocial issues identified by ACOG were operationalized using National Survey on Drug Use and Health variables...

OBJECTIVE: Individuals are often inaccurate at estimating levels of intoxication following doses of alcohol. Previous research has shown that when required to estimate (BAC) at different time points, participants often underestimate their BACs and amounts of alcohol consumed. The present study aimed to increase drinkers' BAC estimation accuracy after drinking alcohol using mindfulness-based feedback to increase their awareness of the interoceptive cues associated with alcohol intoxication...

OBJECTIVE: This study examined how social associations from a person's social network may be associated with their own alcohol consumption. METHOD: Alcohol consumption behavior was examined among the social networks of 784 survey respondents (54% female, M age = 35.3 years), using egocentric social network analysis. Participants (egos) were recruited via a panel aggregator and completed an online survey about the frequency of their alcohol consumption and that of the 20 most influential people in their lives (alters)...

OBJECTIVE: Craving predicts smoking, yet existing interventions may not adequately target regulation of craving. We evaluated two versions of regulation of craving-training (ROC-T), a computerized intervention with intensive practice of strategies when exposed to smoking-related images. METHOD: Ninety-two nicotine-dependent daily smokers were randomized to mindfulness-based therapy (MBT) ROC-T focusing on mindful acceptance, and cognitive behavioral therapy (CBT) ROC-T focusing on reappraisal or no intervention control...
