Introduction In recent literature, abnormalities in the metacognitive domain have been pointed out as psychological variables that may account for a wide range of psychopathologies, including gambling disorder (GD). Considering the growing but scattered nature of the research concerning the relationship between metacognition and GD, a systematic review and meta-analysis of the existing results are

Background and hypotheses Extant research has not studied whether norm perceptions differ between young adult cannabis users who do and do not meet screening criteria for problematic cannabis use. Drawing on sociocultural norms research on alcohol, we hypothesized that users meeting screening criteria for cannabis problems would be more likely than those not meeting those criteria to (1) mistakenly

Correlational research suggests that emotion regulation deficits, which are known risk factors for substance addictions, may also play a role in the development of problem behaviors such as excessive or maladaptive use of social networking sites (SNS). This study sought to experimentally assess the hypothesized emotion regulatory function of SNS use. 139 undergraduates (53.2% female) were randomized

Background Tobacco use often begins or stabilizes in young adulthood. Approximately 90% of young adults use social media and over 80% own a smartphone. Retailers of electronic nicotine delivery systems (ENDS) have targeted smartphones and social media with adverting campaigns. Despite evidence of ENDS advertising on social media and smartphones, few studies have examined associations between exposure

Objective Problematic alcohol involvement in college students remains a public health concern and identifying factors that promote this consequential behavior as it occurs in daily life is critical. Recent work has found that whether a drinking event is unplanned vs. planned has implications for the risk of negative consequences, though less work has identified fine-grained predictors of these two

Several scales assessing problematic pornography use (PPU) are available. However, in most previous studies, primarily nonclinical and Western samples were used to validate these scales. Thus, further research is needed to validate scales to assess problematic pornography use across diverse samples, including subclinical populations. The aim of the present study was to examine and compare the psychometric

Introduction In jurisdictions that have legalized recreational cannabis, perceptions of the ‘legal’ market may influence whether consumers transition from illegal retail sources. The current study examined consumer perceptions of legal versus illegal retail sources in 6 US states with legal retail sales as of 2018: Alaska, California, Colorado, Nevada, Oregon, and Washington State. Methods Data are

Aims To explore the process of applying counterfactual thinking in examining causal predictors of substance use trajectories in observational cohort data. Specifically, we examine the extent to which quality of the parent-adolescent relationship and affiliations with deviant peers are causally related to trajectories of alcohol, tobacco, and cannabis use across adolescence and into young adulthood

Introduction Progesterone has been implicated as protective against drug taking behaviors, including combustible cigarettes. While prior research indicates higher endogenous progesterone levels are associated with a reduction in smoking intensity (as measured by smoking topography), it is unknown if exogenous delivery of progesterone may have the same effect. Methods This double-blind, counterbalanced

The association between cigarettes per day (CPD) and CPD-calibrated polygenic risk scores (CPD-PGS) is positive, however, the shape of the association is unknown. CPD measurement is inconsistent across studies and different measurement can lead to different results. The pattern shape may also patterns may change over time, given differences in genetic influence on smoking. This study examines the dynamic

Background Credible research emphasizes transparency, openness, and reproducibility. These characteristics are fundamental to promoting and maintaining research integrity. The aim of this study was to evaluate the current state of reproducibility in the field of addiction science. Design Cross-sectional design. Measurements The National Library of Medicine catalog was searched for all journals using

Background Debate continues over how e-cigarettes have impacted the health of young people, and what regulatory policies should be enacted. The debate has appropriately been informed by quantitative studies, often focused on initiation, prevalence, and product transition among the general population and demographic segments. Factors driving cessation and subjective experiences that motivate young users

Multiline slots are popular electronic gaming machines. Research suggests that particular outcomes on these games, namely losses disguised as a wins or LDWs, may make these games particularly alluring to gamblers. LDWs occur when one wins less than they wager, but the machine celebrates these net losses with flashing lines and winning sounds (e.g., bet a dollar, win back a dime). Players are known

Aims To explore reciprocal relationships between real-time gambling cravings and self-efficacy with gambling behaviour, and the moderating role of gambling, mental health, and addiction-related variables. Design Secondary analysis of a 4-week Ecological Momentary Assessment (EMA) study conducted in Tasmania, Australia. Setting Data were collected via telephone interviews (pre-EMA) and smartphones (EMA)

Shinrin-yoku (‘森林浴’) (i.e., forest bathing), a Japanese wellbeing practice, aims to harmonise a person with a forest by bathing in the forest mindfully using our five senses (Miyazaki, 2018). Practitioners can choose whatever they like to focus on in the forest: different colours of leaves, the sounds of streams, or the warmth of sunshine beaming between leaves. Since the birth of this practice in

Background Often perceived as a safer smoke, Natural American Spirit (NAS) may find particular appeal in communities with strong non-smoking norms. We hypothesized NAS would be more popular in cities with lower smoking prevalence, with the pattern unique to NAS. We tested household income, cigarette taxes, and young adult population as alternative correlates and examined brand specificity, relative

Gaming disorder involving online or offline games has been included in the latest International Classification of Diseases (ICD-11). Recent studies on psychological processes related to gaming disorder have identified a number of maladaptive cognitions that may play a role in developing and maintaining problematic gaming behaviors. However, there have been few studies that have examined whether these

Despite support for the role of self-medication alcohol use in the etiology and maintenance of comorbid posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD), theoretical and empirical models of PTSD-AUD rarely account for the role of common comorbidities in risk processes, such as major depressive disorder (MDD). The current study examined the main and interactive effects of PTSD and

Pain and nicotine dependence are prevalent, co-occurring conditions posited to interact in the manner of a positive feedback loop; however, most research to date has been conducted among tobacco cigarette smokers. Initial evidence suggests that pain is a risk factor for greater e-cigarette dependence, and additional research is needed to examine covariation between pain and e-cigarette use. There is

The present study sought to identify motivational profiles for responsible drinking from a self-determination theory (SDT) perspective among college students. We used data from 507 students who reported drinking alcohol at least once in the past 3 months that were recruited from a random sample of undergraduate students at a Southwestern university. Participants completed an online survey that included

Objectives To examine post-retail marijuana legalization (RML) change in marijuana use frequency and pro-marijuana norms among parents. Methods The Intergenerational Study, a longitudinal panel of parents (N = 668) and children, followed participants from 2002 to 2018, when parents were 27 and 43 years old, respectively. Three quarters of participants (74%) lived in an RML state and 142 (21%) had used

Chasing, or continuing to gamble to recoup losses, is a behavioral marker and a diagnostic criterion for gambling disorder. Research on chasing has focused mainly on adults, whereas the analysis of chasing behavior among adolescents has not received empirical attention in the gambling literature. The aim of the present study was to first investigate the interplay between chasing behavior, craving,

Although Social Network Site (SNS) usage has been shown to be related to online compulsive buying among women, little is known about the mediating mechanisms underlying this association. Based on the Interaction of Person-Affect-Cognition-Execution model (I-PACE) for addictive behaviors and social comparison theory, the present study examined the mediating roles of upward social comparison and state

Evidence suggests that drinking cope (DTC) motivation becomes a greater risk factor for drinking-related problems as individuals progress through young adulthood. To test this, we examined how the effect of DTC motivation on a variety of drinking-related problems, controlling for drinking level, changed as individuals made the transition from college life to post-college life. We also included social

Introduction The current study examines the norms-behavior link by investigating a novel cognition for protective behavioral strategies (PBS)—descriptive and injunctive norms for close friends’ reasons to use PBS (e.g., limit drinking, reduce consequences)—in relation to one’s own perception of usefulness and personal use of PBS. Further, we tested whether the association between perceived norms for

Introduction A surge in popularity of e-cigarettes prompts concern given the association between e-cigarettes and future cigarette use. However, much of the evidence for this association comes from early, less efficient and lower nicotine e-cigarettes than are available and widely used now. The goal of this study was to examine the relationship between e-cigarette use in 2018 and subsequent smoking

Background Buprenorphine is first-line opioid agonist therapy for opioid use disorder. Standard regimens require that patients be in opioid withdrawal prior to induction, which is a barrier for many. Micro-induction is a novel induction approach that does not require patients to be in withdrawal. Our primary objective is to synthesize available evidence on the effectiveness of micro-inductions on patient

Repetitive negative thinking (RNT), the most studied forms of which are depressive ruminations and anxious worry, is a unique transdiagnostic process responsible for the development and maintenance of many mental disorders. Over the past decade, studies have shown that RNT could be involved in the development and maintenance of alcohol use disorder (AUD). However, to date, little is known about the

Previous research has established coping-motivated use to be the most problematic form of substance use. While dispositional mindfulness and self-compassion have been associated with lower levels of coping-motivated use in undergraduate students, possible mechanisms underlying these relationships have never been tested. The present two-part study examines whether specific emotion-regulation processes

Background The hardening hypothesis proposes that as smoking rates decline, the remaining smokers will become hardcore and resistant to quitting. This group of highly resistant quitters will potentially require more individualistic approaches to cessation and harm reduction. The harm reduction approach (specifically e-cigarettes) has been proposed as an option to address hardened Australian smokers

Drunkorexia is characterized by a group of behaviors designed to minimize caloric intake while maximizing levels of alcohol intoxication. Individuals plan and modify their diet, via skipping meals, exercising, or purging, to save calories for a night of alcohol consumption. Minimal research has examined risk factors related to drunkorexia, and little is known regarding associated problems. We used

Insight refers to a person’s understanding of themselves and the world around them. Recent literature has explored people’s insight into their substance use disorder (SUD) and how this is linked to treatment adherence, abstinence rates, and comorbid mental health symptoms. The aim of this systematic review was to synthesise and critically examine the existing literature on insight in SUD. Five academic

Introduction Minority stress theories suggest that high rates of discrimination experienced by transgender people are precipitants of substance use. This risk is likely exacerbated by an inadequate provision of trans-inclusive substance misuse services. However, the exclusion of transgender people from the general substance misuse literature makes it difficult to determine the extent to which transgender

Background Adolescent cannabis use is perceived as a risky behavior, has been linked with many negative health outcomes, and is increasingly being connected with stigma. Methods The purpose of this study is to investigate how cannabis use is associated with potentially stigmatizing markers of identity among adolescents two waves of a repeat cross-sectional survey (2015 N = 12,110; 2017 N = 15,191)

The steep rise of smartphone use has raised public concerns about smartphone addiction and its associated negative health consequences, such as poor sleep quality; however, limited research has examined the psychological mechanisms underlying these associations. The current study tested the effects of smartphone addiction on poor sleep quality, through self-regulation and bedtime procrastination, among

Objective The concept of self-medication refers to the use of substances to help cope with periods of psychological distress. This study sought to examine the typical drinking patterns of adults who self-report using alcohol to self-medicate low mood using data from a large, nationally representative US household survey. Materials and methods: Data was from the Wave I (2001-2002) National Epidemiological

Introduction Smoking is more prevalent in smokers from lower compared with higher socioeconomic (SES) groups, but studies are inconsistent regarding underlying mechanisms. We aimed to assess associations between SES indicators and three distinct aspects of the smoking cessation process: attempting to quit; use of evidence-based cessation treatments; and success. Methods We analysed data of 12,161 last-year

Alcohol and marijuana misuse is prevalent on many university campuses, with high rates of undergraduate students reporting experiencing alcohol and/or marijuana-related problems, which have been consistently associated with coping-motivated use. While previous studies have found dispositional mindfulness to be negatively associated with coping motives and alcohol-related problems, the present two-part

Aims Time to first cigarette (TTFC) after waking is a highly regarded and readily measured manifestation of a tobacco dependence process. We aim to estimate short TTFC as it occurs very soon after the onset of cigarette smoking (CS) in a community sample of newly incident smokers, all 12–21 years of age, and to study risk variation with the age of CS onset. Methods United States National Surveys on

Background Fatal drug overdose in the United States is a public health crisis fueled by increased opioid and polysubstance use. Few studies have compared the neighborhood-level socioeconomic characteristics associated with overdoses of various substance classes and, to our knowledge, no investigation has yet assessed these factors in relation to polysubstance overdoses. Further, no study has determined

Background Delay Discounting (DD) relates to more frequent cannabis use, but results are variable, potentially because of variations in whether integrated or single-item measures are used, and whether the timeframe of measures is narrow or broad. Explicating the relationship between DD and cannabis use may result from comparing use indices that vary on these characteristics. Methods This online study

Although veterans with posttraumatic stress disorder (PTSD) are particularly vulnerable to opioid misuse and overdose, there is no research evaluating the psychiatric, social, and medical sequalae experienced by veterans with comorbid PTSD and opioid use disorder (OUD). Using data from a nationwide, longitudinal registry of Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) veterans, we identified

Concurrent use of electronic cigarettes (e-cigarettes) as an alternative source of nicotine may lead to lower smoke exposure, tobacco addiction and reinforcing value of conventional combustible cigarettes. In two different cohorts, we characterized smokers, dual cigarette/e-cigarette users, and e-cigarette-only users in terms of sociodemographic, motives and patterns of e-cigarette use. Differences

Introduction Growing rates of e-cigarette use among youth have reached epidemic proportions. Media messages have been deployed to counteract this trend, but their evaluations are lacking. We assessed youth’s and parents’ reactions to various existing e-cigarette prevention messages. Methods In 2019, 12 focus groups were conducted with youth (n=63) and parents (n=27). Participants discussed their reactions

Background Veterans are particularly vulnerable to experiencing concurrent issues related to depression and alcohol misuse. Despite this well-established susceptibility, research explicating targetable mechanisms that can account for this comorbidity remains limited. The present study sought to examine the explanatory role of ruminative thought processing within the depression and alcohol misuse relationship

Introduction Preventing adolescent alcohol use is an international public health priority. To further understand adolescent alcohol use, this study tested a model of adolescent intention to consume alcohol that incorporated multiple social systems influences. Methods Participants included 2529 Australian secondary school students (Mage = 14.20; 53.7% female). Participants completed a survey about risk

Background Behavioral flexibility –the ability to dynamically readjust our behavior in response to reward contingency changes– is often investigated using probabilistic reversal learning tasks (PRLT). Poor PRLT performance has been proposed as a proxy for compulsivity, and theorized to be related to perseverative gambling. Previous attempts to measure inflexibility with the PRLT in patients with gambling

Introduction Multiple tobacco product (MTP) use is a growing public health concern, particularly among adolescents and young adults. This study identifies subgroups of MTP use among cigarillo users and examines associations with nicotine dependence (ND). Methods 1,089 youth (ages 14-28) who currently smoke cigarillos completed a web-based survey regarding their current use of cigarillos, little cigars

Background Opioid use disorder (OUD) is associated with cognitive dysfunction. Understanding how pharmacotherapy may affect cognition is an important treatment consideration. Methods This was a hybrid residential-outpatient, randomized trial assessing transition regimens (naltrexone/buprenorphine [NTX/BUP] vs placebo-NTX/buprenorphine [PBO-N]/BUP) to extended-release naltrexone (XR-NTX) in patients

Background Negative urgency –the tendency to lose control under the influence of strong negative emotions– has been proposed to be a sign of malfunctioning emotion regulation mechanisms, and to contribute to severity and complications of gambling disorder and other externalizing behaviors. Aims and method: This study is aimed at (1) testing whether negative urgency is linked to resistance to extinction

Introduction Young adults who smoke cigarettes often report heavy episodic drinking (HED) and co-use of other psychoactive substances which may complicate efforts to quit cigarette smoking. The current study examined factors associated with readiness to quit cigarette smoking among young adults who smoke and engage in HED. Methods One hundred seventy-nine young adults aged 18 to 25 who reported regular

Background and Objectives Educational programs are needed to combat the sharp rise in adolescent e-cigarette use. We evaluated the impact of an educational session, based on the Stanford Tobacco Prevention Toolkit, on adolescents’ knowledge, perceptions that e-cigarettes are not harmful and addictive, and future intent to try e-cigarettes. Methods We conducted a pre- and post-test study among middle

Gambling disorder (GD) patients show excessively risky decision-making in the financial domain. We aimed to clarify whether GD patients show risky decision-making in domain-general or in domain-specific. Furthermore, we also investigated the effect of the well-known cognitive bias, the framing effect on GD's decision-making under risk. Sixty-two male GD patients and 74 age-matched healthy male controls

AIMS People who have experienced adverse childhood experiences (ACEs) are more susceptible to substance use disorder (SUD) and depression. The present study examined depression prevalence in hospitalized patients with SUD and examined the association of individual ACEs with major depression. Depression rates 3 months after discharge were also examined. METHODS Medical inpatients with SUD were recruited

Problem gambling has been linked to impairments in decision-making under uncertainty. Problem gamblers are more likely to favor high-risk, high-reward, and short-term gains over more advantageous choice alternatives, and this preference has been linked to impaired learning about decision outcomes. In this paper we link specific learning processes in decision-making to specific harms related to problem

Adolescent Internet addiction is an important social issue entailing extensive use of Internet and smartphones and its side effects. This study identified relevant psychological factors that affect excessive Internet use (EIU) and excessive smartphone use (ESU) in adolescents using structural equation modeling (SEM). A sample of 714 individuals drawn from lists of middle school students in South Korea

BACKGROUND Alcohol use among Chinese vocational school students is widespread and associated with many negative consequences. However, alcohol-specific antecedents for this population are understudied. OBJECTIVES The current study explored: (a) which alcohol-specific antecedents are the most salient predictors for alcohol use intentions, (b) whether any mediational relationships exist among these alcohol-specific

Gambling disorder and other comorbid addictive disorders may have similar underlying affective and motivational patterns. This study aims at examining the association between gambling disorder, comorbid addictive disorders (i.e., alcohol, drugs, spending, and videogames), positive and affective mood, and gambling motives in a community sample. A sample of 1099 adolescents and young adults was recruited

BACKGROUND AND AIMS Recent research has suggested that metacognitions may play a role across the spectrum of addictive behaviours, including problematic use of technological devices. Metacognitions associated with problematic Smartphone use (PSU) have been scarcely investigated and measures to assess these beliefs are not yet available. The goal of the present study was: (i) to develop the first self-report

BACKGROUND Few studies have examined predictors of exclusive e-cigarette use, exclusive smoking and dual use among youth. We investigated whether frequency of e-cigarette use and cigarette smoking predicted involvement in different usage groups after a 1- and 2-year follow-up among a sample of Canadian youth. METHODS A longitudinal sample of youth who participated in three waves of COMPASS [Wave 1
