Introduction

Drinking motives and neurocognition play significant roles in predicting alcohol use. There is limited research examining how relief-driven drinking motives interact with neurocognition in alcohol use, which would help to elucidate the neurocognitive-motivational profiles most susceptible to harmful drinking. This study investigated the interactions between neurocognition (response inhibition and cognitive flexibility) and relief-driven drinking, in predicting problem drinking.

Methods

Participants completed the Alcohol Use Disorders Identification Test – Consumption items (AUDIT-C) to measure drinking behaviour, and online cognitive tasks, including the Value-Modulated Attentional Capture and Reversal Task (VMAC-R) and the Stop Signal Task (SST). The sample (N = 368) were individuals who drink alcohol, which included a subsample (N = 52) with problematic drinking, as defined by self-identifying as having a primary drinking problem. Drinking motives were assessed using a binary coping question in the overall sample, and the Habit, Reward, and Fear Scale (HRFS) in the subsample. Moderation analyses were conducted to investigate whether cognitive flexibility and response inhibition moderated relationships between relief-driven motives and drinking.

Results

Cognitive flexibility moderated the relationship between relief-driven motives and drinking (overall sample: β = 13.69, p = 0.017; subsample: β = 1.45, p = 0.013). Greater relief-driven motives were associated with heavier drinking for individuals with low cognitive flexibility. There was no significant interaction between response inhibition and relief-driven motives.

Conclusions

Relief-driven drinking motives interact with cognitive inflexibility to drive heavier drinking. Greater understanding of these neurocognitive-motivational mechanisms may help to develop more targeted and effective interventions for reducing harmful drinking.

Objective

The neurocognitive risk mechanisms predicting divergent outcomes likely differ between men and women who use cannabis recreationally. Increasingly, the use of descriptive distributions including the ex-Gaussian has been applied to draw stronger inferences about neurocognitive health in clinical populations. The current project examines whether the long tail of reaction times (RTs) in a distribution, as characterized by the ex-Gaussian parameter tau which may represent difficulty with the regulation of arousal, predicts problematic cannabis use 6 months later in those who use cannabis recreationally, and whether sex moderates these prospective associations.

Method

Young adults (ages 18–30, mean age 20.5 years, N =159, 57.2% women, 69.2% Caucasian) who recreationally used cannabis either occasionally (at least once per month) or frequently (three times or more per week) completed the Stroop Color-Word Task at baseline. Ex-Gaussian parameter tau was estimated for each participant. Self-report of hazardous cannabis use (CUDIT-R) and dysregulation of negative (DERS) and positive emotions (DERS-Positive) were obtained at baseline and 6-month follow-up.

Results

For those with larger tau at baseline, being a man (but not a woman) was associated with increased difficulty regulating positive emotions concurrently (b = −0.01, F (1,159) = 5.48, p = 0.02), and with hazardous cannabis use six months later (b = −0.007, F (1,159) = 4.42, p = 0.037) after controlling for baseline hazardous cannabis use.

Conclusions

Excessively long RTs during cognitive performance may help characterize men at risk for increased hazardous use, which contributes to understanding between-sex heterogeneity in pathways towards cannabis use disorders.

Background

Sober living houses (SLHs) offer abstinence-based housing for people in recovery. Studies have shown that these supportive environments are associated with positive outcomes, yet little is known about why residents choose SLHs and their relationship to recovery outcomes.

Methods

Longitudinal data were collected from SLH residents who completed an interview six months after baseline (N = 462). Participants rated the importance of eight reasons for choosing SLHs. Multilevel models assessed whether reasons for choosing were associated with outcomes abstinence on the Timeline Followback, psychiatric distress via the Psychiatric Diagnostic Screening Questionnaire (PDSQ), employment problems severity on Addiction Severity Index (ASI), and length of stay (LOS).

Results

The most frequently cited reasons residents chose SLHs were affordability (74.4 %) and wanting to live with others in recovery (63.2 %). Reasons for choosing were not associated with neither LOS nor abstinence, except for not wanting to live with others in recovery predicting abstinence from all drugs except marijuana. Choosing SLHs due to affordability was associated with less psychiatric distress; no other place to live was associated with increased psychiatric distress (Ps < 0.05). Severity of employment problems was associated with choosing SLHs based on location, transportation, and someone else paying fees (Ps < 0.01).

Conclusion

Residents seek entry into SLHs to live affordably with others in recovery. Those who had no other option had greater psychiatric distress, thus supporting findings of housing instability being related to mental health. Reasons for choosing related to employment problems severity may reflect how concerns about employment impact housing choices.

Aims and background

Singapore has one the world’s strictest e-cigarette (vaping) regulations, with bans on e-cigarette import, sale, purchase, use and possession. Nevertheless, Singapore is seeing a growing vaping trend. Beyond estimates of vaping prevalence, little is known about vaping in countries where it is banned or the features and drivers of such illegal vaping cultures. This qualitative study thus explored the characteristics of Singapore’s illegal vaping culture.

Methods

We held ten focus group discussions with 63 Singaporeans aged 21–40 years, exploring participants’ experiences and views related to vaping in Singapore. Transcripts of the discussions were coded using deductive and inductive coding methods.

Results

Despite its illegal status, vaping was perceived as appealing due to the novelty flavours, ease of use, and convenient access. Harm perceptions were mixed, with concerns over the adverse health impacts along with beliefs that vaping was innocuous when used in moderation. A conspicuous vaping culture among young people, along with perceptions of lax enforcement, drove beliefs that vaping is an entrenched social norm in Singapore. This belief was in turn associated with a sentiment that Singapore should introduce a regulated e-cigarette market to better control its use among the general population.

Conclusions

The reinforcement of vaping as a social norm appears to be driving an illegal vaping culture in Singapore. Measures that denormalise vaping could help to strengthen the effectiveness of the vaping ban.

Digital games are widely popular and integral to contemporary entertainment. Nevertheless, a proportion of users present with disordered/excessive gaming behaviours, provisionally classified as Internet Gaming Disorder (IGD). Previous literature suggests examining the contribution of an individual’s profile of immersive engagement with their gaming activity, known as online flow, for disordered gaming behaviours. Therefore, the main goals of this study were (1) to categorise gamers into distinct profiles based on their online flow experiences and (2) to investigate the differences in disordered gaming among these different flow profiles. A sample of 565 gamers (12–68 years, Mage = 29.3 years) was assessed twice over six months with the Online Flow Questionnaire (OFQ), the Internet Gaming Disorder Scale-Short-Form (IGDS9-SF), and the Gaming Disorder Test (GDT). Latent profile analysis (LPA) identified five distinct profiles encompassing ’High-Flow with High Loss of Control’ (HF-HLOC; 14.0 %), ’Low Flow with Low Enjoyment’ (LF-LE; 11.9 %), ’Average Flow with Low Enjoyment’ (AF-LE; 17.5 %), ’Low Flow with High Enjoyment’ (LF-HE; 20.2 %), and ’High Loss of Sense of Time with Low Loss of Control’ groups (HLOT-LLOC; 36.5 %). As hypothesised, individuals across varying profiles evidenced differences in their concurrent and longitudinal disordered gaming behaviours. Overall, findings suggest that ’loss of sense of time’ may be the most pivotal factor in differentiating flow states and profiles during gaming, advocating its consideration in disordered gaming assessment and treatment.

Background

Among sexual minorities (SMs), experiencing discrimination has been associated with greater substance use at the day-level. However, variations in sample characteristics and measures of day-level discrimination limit the generalizability of findings. Furthermore, it is unknown how positive experiences due to minority identity (“Minority Strengths”) may impact the association between experiencing discrimination and same day drinking.

Methods

The present study extends prior research on discrimination and drinking using detailed discrimination measures, Minority Strengths measures, and a gender diverse sample. Participants (N = 61) were majority White (n = 45, 73.8 %) adult (mean age 26.8 years) self-identified SMs (e.g., 44.3 % identified as “gay”) who engaged in alcohol use within the past month. Participants completed up to 31 days of daily diary surveys about their experiences and drinking. Recruitment took place in the northeastern U.S. from May to December 2021.

Results

Multilevel model analysis indicated that experiencing discrimination was associated with increased same day drinking among Black, Indigenous, people of color (BIPOC) participants but not among White participants. A significant gender by discrimination interaction indicated that cisgender men drank more the same day they experienced discrimination compared to cisgender women and transgender/non-binary participants. Minority Strengths had no impact on these relationships.

Conclusions

Results highlight that the experience of discrimination and its association with drinking may be influenced by a host of contextual factors that are attached to racial and gender identities. Future research should examine how discrimination in different contexts (e.g., regions) and based on specific identities may be associated with alcohol use.

Introduction

Substance use (SU) and mental health (MH) concerns often occur as students transition from high school to college and may be associated with first semester experiences.

Methods

Incoming first-year college students at a U.S., predominantly white, midwestern university were recruited for an intervention study. Participants reported on substance use, mental health, and college experiences at the end of their first semester of college (n = 781; 62.9 % female, mean age = 18.06 [SD = 0.24]; 77.2 % non-Hispanic white; 84.6 % heterosexual). Data for these current analyses were cross-sectional.

Results

Identifying as Black, Indigenous, or another Person of Color, as a sexual minority, or as female was associated with more challenging first semester experiences. Social experiences that represent more social engagement were associated with greater substance use. College experiences reflecting an easier transition were associated with fewer mental health concerns. Alcohol use moderated the relation between academic challenges and mental health with stronger associations found at greater levels of alcohol use.

Conclusions

First semester experiences were related to student mental health and substance use, suggesting the importance of early, targeted support for students to adjust to campus life.

Introduction

Use of amphetamine-type stimulants (ATS) contributes substantially to the global burden of disease. Large-scale follow-up studies of morbidity and mortality in ATS users are few. This study analysed morbidity, mortality, and potential predictors of all-cause mortality in a nationwide cohort of patients with ATS use disorder.

Methods

Data was acquired from national Swedish registers. All Swedish residents 18 years or older, with a registered ATS use diagnosis in 2013–2014 were included (N = 5,018) and followed until December 31, 2017. Comorbid diagnoses and causes of death were assessed and potential predictors of all-cause mortality were examined through Cox regression.

Results

Median age at inclusion was 36.6 years (interquartile range 27.4–––48.1) and 70.5 % were men. The crude mortality rate was 24.6 per 1,000 person-years. The adjusted all-cause standardized mortality ratio was 12.4 (95 % CI [11.34–13.55]). The most common cause of death was overdose (28.9 %). Multiple drug use (hazard ratio 1.39, 95 % CI [1.14–1.70], p = 0.004), anxiety (hazard ratio 1.39, 95 % CI [1.11–1.72], p = 0.014), viral hepatitis (hazard ratio 1.85, 95 % CI [1.50–2.29], p = 0.004), and liver disease (hazard ratio 2.41, 95 % CI [1.55–3.74], p = 0.004) were predictors of all-cause mortality.

Conclusions

Multiple drug use, anxiety disorders, viral hepatitis and liver diseases were identified as risk factors for death. Our findings call for better screening, prevention, and treatment of somatic and psychiatric comorbidity among ATS users to reduce mortality.

The disclosure of recovery journeys on social media by individuals with substance use is a growing trend, but its impact on public attitudes toward stigmatized groups is not well-understood. To address this gap, an experiment was conducted with 1,438 U.S. adults who viewed a series of Instagram posts about a person’s recovery journey. Participants were randomly assigned to view posts that either included a relapse episode or not. Structural equation modeling was used for data analyses. The results revealed that presenting a relapse narrative increased feelings of compassion, anger, and pity. In addition, mediation analyses provided evidence supporting the role these emotions played in mediating the effects of a relapse narrative on stigma beliefs and desire for social distance. These findings prompt a reevaluation of digital storytelling practices in health communication strategies, aiming for a balanced representation that can effectively reduce stigma and promote community support for those navigating substance use recovery. It is recommended to incorporate the study’s insights into educational content, therapeutic interventions, and policy formulations to foster a more supportive and understanding environment for individuals in recovery.

Problematic pornography use is a growing area of interest necessitating a deeper understanding of its contributing factors. Loneliness and emotion regulation difficulties have been advanced as factors that may exacerbate or perpetuate PPU, however, to date, researchers typically consider these factors in isolation. In addition, the evolving landscape of problematic pornography is further shaped by the emergence of pornography content creators. This study explores the relationships between loneliness, emotion regulation difficulties and problematic pornography use and individuals’ interactions with pornography content creators. Specifically, we examine whether emotion regulation difficulties mediate the relationship between loneliness and PPU and whether this mediation is contingent on interactions with content creators. A total of 213 adults (M_age = 35.57 years, SD = 16.90; 77.50 % men) participants completed an online questionnaire assessing PPU, emotion regulation difficulties and loneliness. Results revealed loneliness is associated with increased PPU and emotion regulation difficulties. Emotion regulation difficulties, in turn, relate to PPU. Though interaction with pornographic content creators was associated with reduced PPU, interacting with content creators did not moderate the effect of emotion regulation on the relationship between loneliness and PPU. Our findings support the hypothesised model, suggesting that emotion regulation difficulties mediate the relationship between loneliness and PPU. The identified mediating role of emotion regulation difficulties provides a foundation for further investigations into the underlying mechanisms connecting emotional well-being and problematic pornography use, offering potential directions for future research.
