Background: Relationships between gambling motives and problem gambling have been identified in previous research. There is, however, evidence of moderate-to-high heterogeneity in these associations, suggesting that further research is required to elucidate which gamblers are more susceptible to the influence of different types of motives. This study aims to (1) explore the relationship between gambling motives (Gambling Motives Questionnaire-Financial coping, enhancement, social, financial) and problem gambling (Problem Gambling Severity Index); and (2) investigate the degree to which psychological variables implicated by the pathways model (positive reinforcement high-risk situations, negative reinforcement high-risk situations, psychological distress, emotional dysregulation, distress intolerance and impulsivity) moderate these relationships.

Methods: A convenience sample of 342 past-month gamblers (M = 29.09, SD = 10.39), who were mostly classified with low-risk, moderate-risk or problem gambling (90.14 %), completed an online survey including an assessment of gambling motives, problem gambling, and these psychological variables.

Results: All gambling motives positively predicted problem gambling (OR = 1.18-1.59, p < 0.001). In the moderation analyses, significant interaction effects were found between coping motives and lack of clarity (emotional clarity) (OR = 1.05, p = 0.024), all motives and distress tolerance (OR = 0.95-0.96, p=< 0.001-0.006), and enhancement motives and positive urgency (OR = 1.03, p = 0.020).

Conclusions: This is the first known study to use psychological variables explicated by the pathways model to moderate the relationship between gambling motives and problem gambling, with a view to explaining some of the heterogeneity in these relationships. The identification of significant interactions has clinical implications for the development of targeted prevention and intervention programs.

Introduction: Evidence shows the inconsistencies in perceived harm of e-cigarettes between direct (single question) and indirect (assessing perceived harm separately by a single question and subtracting their score) measures. While the validity of both measures was tested by assessing their association with criterion variables (i.e., ever-trying e-cigarettes), further validation research is needed given existing limitations.

Methods: We analyzed data from Population Assessment of Tobacco and Health Study Wave 6 in the US and a provincial version of the Global Adult Tobacco Survey 2020 in Vietnam. Comparative harm of cigarettes and e-cigarettes was measured using direct and indirect method. A new criterion validity measure - "I use e-cigarettes because they might be less harmful to me than smoking cigarettes" - was introduced.

Results: In the general US population, a higher proportion of participants perceived e-cigarettes as less harmful than cigarettes when assessed using the indirect method compared to the direct method (31.56% vs. 13.70%). Additionally, although many US e-cigarette users indicated that they used e-cigarettes because they might be less harmful than cigarettes, among these people only 61.43% reported e-cigarettes to be less harmful when using the direct method but this proportion was higher (67.28%) for the indirect method. In Vietnam, this proportion was higher, at 76.68% using the direct method.

Conclusion: This study emphasizes the significance of including and reporting multiple measures within a single survey to achieve a comprehensive understanding of perceived harm.

Accessing the Internet is one of the most frequent free-time activities among autistic and non-autistic adolescents. Autistic individuals may experience communicative benefits from using the Internet. However, they may also be at risk of developing Problematic Social Media Use (PSMU). To date, PSMU in autistic adolescents remains underinvestigated, and no research has analyzed the role of emotional correlates. The present study aims to investigate possible differences in terms of PSMU comparing autistic participants to their non-autistic peers, and examine the role of two dimensions of social anxiety (i.e., humiliation/refusal and performance anxiety) as reported by both children and parents in worsening the levels of PSMU. A total of 183 participants (76 on the autism spectrum), aged (8-17 years) participated in the study. Questionnaires on social media use and on social anxiety were administered. Moreover, parents of the participants were asked to complete a questionnaire related to their children's social anxiety. Results showed similar levels of PSMU across the two groups. However, a different pattern of relationships between PSMU and age, and the two dimensions of social anxiety was observed in autistic adolescents as compared to the non-autistic peers, revealing that individual characteristics and specific social anxiety beliefs might be relevant to understanding PSMU in autism. The clinical and preventive implications of these findings are discussed.

Background: Cannabis vaping, and co-use with cannabis smoking, can exacerbate the risks of developing respiratory diseases and cannabis dependence. This study aims to examine the mental health profiles and sociodemographic correlates of adults who vape cannabis and engage in dual cannabis use (vaping/ smoking), compared to those who smoke cannabis.

Methods: The most recent, cross-sectional wave of the Population Assessment of Tobacco and Health Study (Wave 6) was used in this study. Data were restricted to adults (18 + years) who currently use cannabis (n = 7,178). Participants were classified as 'cannabis smoking only,' 'cannabis vaping only,' 'dual-use,' or 'other cannabis use methods only.' Multinomial logistic regression was used to examine the sociodemographic, internalizing and externalizing symptom factors of cannabis vaping and dual-use compared to cannabis smoking.

Results: Over 56 % of participants currently smoked cannabis only, 9.1 % vaped cannabis only, while 20.0 % were engaging in dual-use. Adults experiencing severe externalizing symptoms (vs. mild symptoms) had higher odds of engaging in dual-use than smoking cannabis only (OR = 1.89, 99.5 %CI: 1.48, 2.40). Those with White racial background (vs. African-American background) (OR = 3.90, 99.5 %CI: 2.31, 6.58) and earning a higher income (vs. lower income) (OR = 2.56, 99.5 %CI: 1.79, 3.66) had higher odds of currently vaping cannabis only, compared to smoking cannabis only.

Conclusions: Our study has identified that mental health plays a significant role in cannabis use patterns, particularly with externalizing symptoms which are related to aggression and diagnoses of attention deficit disorders. This highlights the need for healthcare and mental health providers to address mental health symptoms when managing adult cannabis use.

Limited research indicates impulsivity and sensation-seeking are associated with electronic nicotine delivery systems (ENDS) use in young adulthood, however, no study has examined the moderating effect of peer ENDS use on these associations. We examined the impacts of impulsivity and sensation-seeking on ENDS use initiation and determined if peer ENDS use moderates these associations. Participants were 2,590 ENDS naïve (i.e., never used ENDS) young adults involved in multi-wave, 4.5-year longitudinal study (Fall, 2014 - Spring, 2019). At baseline, participants were 18-25 years old (M = 20.1; SD = 1.8), 66.5 % female, 34.2 % non-Hispanic white, 28.1 % Hispanic/Latino, 8.6 % Black, 21.6 % Asian, and 7.4 % identified as another race/ethnicity. Cox's regression models were used to test hypotheses. Predictors were time-varying impulsivity and sensation-seeking, and the moderator was time-varying peer ENDS use. The outcome, ENDS use initiation, was assessed by querying ever ENDS use over 7 follow-up waves. Covariates included socio-demographic characteristics, past 30-day other tobacco use, cannabis use, and binge drinking. Nearly 29% of participants initiated ENDS use during the study period. Sensation-seeking predicted an increased risk of initiating ENDS use (HR = 1.12, 95 %CI:1.03,1.22), but impulsivity did not. Although peer ENDS use directly predicted an increased risk for initiating ENDS use (HR = 1.57, 95 %CI:1.46, 1.68), peer ENDS use did not moderate the associations of impulsivity and sensation-seeking on ENDS use initiation. The role of sensation-seeking on ENDS use initiation is independent of peer use. Prevention programs tailored to those high in sensation-seeking may consider changing attitudes about how desires for novel experiences can be achieved through healthier behaviors.

The presentation of comorbid post-traumatic stress disorder (PTSD) and substance use disorder (SUD) differs by substance type. The current study applied network analysis to explore the relationships between diagnostic symptom clusters by examining the strength and direction of unique associations between PTSD and SUD. Network analyses were estimated using a sample of 422 veterans diagnosed with co-occurring PTSD/SUD initiating psychotherapy for PTSD while receiving concurrent outpatient SUD treatment as part of a randomized clinical trial. Separate network models were estimated for PTSD and the three most common SUD in the sample: alcohol use disorder (AUD), cannabis use disorder (CUD) and stimulant use disorder (StUD). Trauma-related intrusions and alcohol-related social impairment were the bridging symptom clusters that connected PTSD and AUD. Symptom clusters that connected PTSD and CUD were trauma-related intrusions and hyperarousal symptoms. Trauma-related alterations in cognition and mood and stimulant-related pharmacological symptoms were the bridging symptom clusters that connected PTSD and StUD. Each network of symptom clusters culminated in the trauma-related avoidance cluster, suggesting avoidance may represent a final outcome of the downstream effects of these symptoms. Across models, PTSD and SUD symptom clusters both served as sources of activation driving the comorbidity. There were also few and relatively weak bridging symptom clusters that connected PTSD/SUD, suggesting symptom change in one disorder may have minimal effect on the other disorder. Therefore, simultaneously treating PTSD and SUD as well as employing individualized treatment planning to target prominent symptoms may be most beneficial for veterans with PTSD/SUD.

Introduction: We conducted this review to examine the risk of e-cigarette dependence in different populations by updating the review on this topic by the National Academies of Science, Engineering, and Medicine.

Methods: Six academic databases were searched for studies published between September 2017 and December 2023. We included peer-reviewed human, animal, cell/in vitro original studies examining associations of e-cigarette use and dependence but excluded qualitative studies. Three types of e-cigarette exposure were examined: acute, short-to-medium term, and long-term. Meta-analysis were conducted when possible. Different risk of bias tools were used for assessing quality of the included human studies.

Results: We included 107 studies, of which 34 studies were included in the subgroup analysis. Meta-analyses showed that non-smoker current vapers had no statistically significant difference in level or prevalence of dependence compared to non-vaper current smokers and dual users. However, never smoker current vapers had a lower level of dependence (SMD -0.723, p < 0.01) compared to dual users, which was also supported by ANOVA test. Narrative review findings suggest that nicotine vapers had higher level of dependence than non-nicotine vapers and e-cigarette dependence is positively associated with nicotine concentration, frequency, and duration of use. No strong relationship was found between dependence and product types or features. Socio-demographic factor-based subgroup findings were inconclusive.

Conclusions: The level and prevalence of e-cigarette dependence is similar to cigarette dependence. There was high variability in the definitions and methods used for defining populations and assessing dependence. Further research and monitoring are crucial.

Alcohol use is prevalent among young adults, with significant rates of binge drinking and frequent reports of both positive and negative consequences. The current study investigates how positive drinking consequences influence subsequent incentives ratings and drinking behavior. Utilizing mobile daily diary data from 104 young adults over two weeks (event N = 507), we assessed the impact of event-specific positive consequences on future incentive ratings and drinking quantity. Findings revealed that positive consequences were not consistently associated with higher sensitivity to incentives, opposing hypotheses. Specifically, positive alcohol consequences were associated with a slight decrease in next-event alcohol incentive ratings, contrary to the expected positive feedback loop (b = -0.13, p = 0.03). While previous event experiences did not significantly moderate the relationship between incentive ratings and drinking quantities, within-subject increases in incentive ratings for social/party (IRR = 0.45, p < 0.001) and alcohol (IRR = 0.39, p < 0.001) incentives were linked to changes in drinking quantity. Results underscore the complexity of the relationship between positive consequences and drinking behavior, indicating that individual differences, experienced consequences, and salient rewards (i.e., incentives) may play crucial roles in future drinking behavior. Future research should explore additional mechanisms of learning and diverse populations to expand on these findings and enhance strategies for reducing risky drinking behaviors.

Purpose: Self-reported drinker identity, the extent to which one views oneself as a drinker, is associated with alcohol consumption and related harms in young adults. The current study examined changes in self-reported drinker identity, theoretically relevant factors associated with drinker identity development, and drinker identity's association with changes in drinking and alcohol-related consequences. We hypothesized that drinker identity would increase over time; theoretically relevant factors would be significantly and positively associated with that increase, and increases in drinking identity would be associated with elevated drinking and related consequences.

Method: Participants were 588 heavy-drinking college students (63 % female, 50.5 % White, Mean_age = 19.87, from two universities) reporting recent heavy episodic drinking and experiencing alcohol-related consequences in the previous month. Students completed baseline and follow-up assessments at 1-, 3-, and 6-months related to theoretically relevant factors, drinker identity, and drinking/related consequences.

Results: Using parallel process latent growth curve modeling, we examined changes in drinker identity as a function of initial levels and changes in theoretically relevant factors. We also examined changes in alcohol use and related consequences as a function of changes in drinker identity. Results indicated that a more favorable initial attitude toward heavy drinking and an increase in favorable attitude toward heavy drinking were associated with an increase in drinker identity. Overall, alcohol use and associated consequences diminished over time, but increases in drinker identity were associated with smaller reductions in alcohol outcomes.

Conclusions: The study highlights the importance of attitudes as a potential contributing factor to drinker identity development, particularly among college students who drink heavily. This work further demonstrates a link between changes in drinker identity and changes in drinking and associated consequences. This work can inform future interventions aimed at targeting drinking identity.

Depression and anxiety are often comorbid among adolescents. Adolescent screen time changes over time. This study investigates the association between screen time trajectories and the comorbidity of depression and anxiety from a longitudinal perspective. The data were collected from an ongoing prospective puberty cohort which was established in 2014 from Chongqing, China. 838 participants (52.03 % female; wave 1 mean age = 8.62, SD = 1.15) were followed up from 2014 to 2020. Questions about screen time were administered every six months. Trajectories of screen time were identified using latent class growth analysis. Children's Depression Inventory (CDI) and Screen for Child Anxiety Related Disorders (SCARED) were used to measure depression and anxiety. Latent profile analysis was used to identify the subtypes of comorbidity of depression and anxiety. Logistic regression was used to explore the association between screen time trajectory and the comorbidity of depression and anxiety. Three distinct trajectories of screen time were identified: Group Low (68.26 %) had consistently low screen time, Group High (26.37 %) had high screen time and Group Increasing (5.37 %) was characterized by an increasing screen time. Four subtypes of the comorbidity of depression and anxiety were fitted ("High comorbidity", "Low comorbidity", "Low depression symptoms" and "No symptoms"). Group Increasing and Group High were associated with "Low comorbidity" and "Low depression symptoms". Group Increasing was more likely to be the "high comorbidity" both boys and girls. However, Group High was associated with "high comorbidity" only in girls. The results of this study may inform future research and provide possible intervention targets.
