Addictive Behaviors Reports最新文献

Background and aims

The concept of impaired control is central to addictive disorders, including gaming disorder in the DSM-5 and ICD-11. Impaired control refers to the recurrent inability to resist impulses to engage in certain activities or behaviours and the failure to limit or stop this engagement. Although numerous screening tools for gaming disorder symptoms have been developed, these instruments have limited capacity for measuring the nature and extent of impaired control. To address this limitation, the present study reports on the creation of the Impaired Control Over Gaming Scale (ICOGS), an 8-item screening tool to assess gaming-related impaired control.

Methods

A total of 513 gamers, including 125 gamers (24.3%) who met the DSM-5 criteria for gaming disorder, were recruited from Prolific, an online crowd-sourcing platform.

Results

The ICOGS demonstrated promising psychometric properties. Exploratory and confirmatory factor analysis using two samples provided robust support for a 2-factor model and high internal consistency of the scale. ICOGS scores were significantly and positively associated with gaming disorder symptoms, gaming-related harms, gaming frequency, psychological distress, and neuroticism. Using receiver operating characteristic analysis, the ICOGS differentiated between non-problem gamers and those who met the criteria for GD.

Discussion and conclusions

Overall, the ICOGS appears to be a valid and reliable scale for use in studies of problem gaming, and may be useful for assessing outcomes of GD interventions that employ self-regulation and stopping techniques to reduce or eliminate problem gaming behavior.

Gambling disorder and cannabis use disorder are both considered major public health issues. Despite the well-documented frequency of substance use disorders among people with gambling disorder, little is known about the experiences of those who both engage with gambling and cannabis. A scoping review was undertaken to investigate studies focusing on the experiences of people who gamble and use cannabis. Unexpectedly, no qualitative or mixed-methods studies that included an in-depth qualitative component to study the lived experiences of this population were found. This absence highlights the critical need to diversify research methods and fill the gap in knowledge of the lived experiences of people who both gamble and consume cannabis.

The effects of COVID-19 on tobacco and cannabis use have been variable, and it is unclear the extent to which factors affecting changes in tobacco and cannabis use differ. The purpose of this study was to identify the COVID-19-related factors that affect changes in tobacco and cannabis use during the pandemic. Focus groups with 114 young adults in California in April 2021 were held to discuss tobacco and cannabis use patterns, adverse events, and the effect of COVID-19 on tobacco and cannabis product use. Factors affecting changes in use were largely similar between tobacco products and cannabis products. Increases in product use were a result of changing social environment, coping with emotional and psychological distress, and product related factors. Decreases in product use were a result of social isolation, COVID-19-related health concerns, disruptions in daily patterns of living, and reduced access. Drivers of increased cannabis use distinct from tobacco or nicotine product use included feeling greater freedom to disengage and perceptions of less harm. Improved understanding of how the pandemic has affected tobacco and cannabis use can inform tailored interventions to both support those who have decreased or quit and assist those who have increased use during the pandemic to reduce or cease their consumption.

Objective

There is a need for low-cost, wide-reaching interventions to enhance accessibility of support for people with hazardous alcohol consumption. We assessed participant experiences of using a novel, personalised mHealth intervention offering approach bias modification (ApBM) for alcohol use in a community sample drinking at harmful levels to enable a deeper understanding of the end user and engagement.

Methods

Eighteen semi-structured telephone interviews were conducted with adults in the community drinking at harmful/hazardous levels. A reflexive thematic analysis approach was used and data analysis followed iterative categorisation.

Results

Engagement/Motivation and Clinical Value were overarching themes. The useable, accessible, customisable design described by participants enabled training to be readily integrated into routines, enhancing autonomy and self-efficacy beliefs, and facilitating engagement/motivation. Where autonomy or perceived self-efficacy were threatened by a rigid training schedule or lack of clarity/reminders, engagement was reduced. Training increased awareness of drinking behaviours, and encouraged participants to consider alternate goal-directed behaviours with feedback suggesting training may function as a ‘circuit breaker’, increasing time between alcohol craving and seeking, and enabling reflective processing, at least in the short term.

Conclusions

This novel smartphone intervention for alcohol use may be a useful, accessible, ‘just in time’ adjunctive support tool for non-treatment seekers, meeting an important gap in the field. Findings have implications for the implementation of subsequent digital interventions, suggesting participants may stand to gain more from an intervention which enables autonomy and improves self-efficacy beliefs. Theoretically, findings speak to the role of inferential processing in behaviour change, but further research is needed to clearly elucidate ApBM training mechanisms. Practical recommendations for subsequent app iterations are suggested, along with additional opportunities worthy of consideration for future initiatives.

Introduction

Self-report and nicotine detection are methods to measure smoking exposure and can both lead to misclassification. It is important to highlight discrepancies between these two methods in the context of epidemiological research.

Objective

The aim of this cross-sectional study is to assess the agreements between self-reported smoking status and nicotine metabolite detection.

Methods

Data of 599 participants from the Netherlands Epidemiology of Obesity study were used to compare serum metabolite levels of five nicotine metabolites (cotinine, hydroxy-cotinine, cotinine N-Oxide, norcotinine, 3-hydroxy-cotinine-glucuronide) between self-reported never smokers (n = 245), former smokers (n = 283) and current smokers (n = 71). We assessed whether metabolites were absent or present and used logistic regression to discriminate between current and never smokers based on nicotine metabolite information. A classification tree was derived to classify individuals into current smokers and non/former smokers based on metabolite information.

Results

In 94% of the self-reported current smokers, at least one metabolite was present, versus in 19% of the former smokers and in 10% of the never smokers. In none of the never smokers, cotinine-n-oxide, 3-hydroxy-cotinine-n-glucorinide or norcotinine was present, while at least one of these metabolites was detected in 68% of the self-reported current smokers. The classification tree classified 95% of the participants in accordance to their self-reported smoking status. All self-reported smokers who were classified as non-smokers according to the metabolite profile, had reported to be occasional smokers.

Conclusion

The agreement between self-reported smoking status and metabolite information was high. This indicates that self-reported smoking status is generally reliable.

Loot boxes are products in videogames that is earned by playing a video game or by buying them. Loot boxes has similar mechanisms as a lottery and there is an ongoing debate if loot boxes are gambling. However, to understand the potential harm of loot boxes valid instruments are needed. An English study psychometrically evaluated an instrument focused on risky loot box use called the Risky Loot Box Index. The study evaluated 12 item scale and based on a factor analysis it was reduced to a five-item scale. The aim of our study is to evaluate a Swedish version of the 12-item instrument from a psychometric perspective. Two samples recruited via an online survey were used. The first sample was recruited from the gambling site Unibet. A mail with an invitation to participate was sent to esports bettors and sport bettors at the gambling site. The second sample was recruited from a Facebook forum focused on e-sports. An invitation was posted on the forum to partake in the study. A total of 195 of respondents (96% men and 4% women) with a mean age of 33.76 (SD = 12.34) answered the Unibet survey and 169 respondents (96% men and 4% women and non-binary) with a mean age of 23.89 (SD = 5.52) answered the Facebook survey. An exploratory factor analysis yielded a two-factor seven item solution. The factors were overconsumption regarding time spent on loot boxes and the other factor was focused on overconsumption of loot boxes in terms of spending money. The confirmatory factor analysis conducted in the Facebook sample validated the result from the exploratory factor analysis. The conclusion of the study is that the Swedish version of the Risky Loot Index has good psychometric properties and can used to measure risky loot box consumption.

Background

Smokeless tobacco use has serious oral health consequences. The purpose of this current research is to determine the level of dental care utilization among individuals with smokeless tobacco use as compared with individuals who do not use smokeless tobacco.

Method

The U.S. national dataset, 2020 Behavioral Risk Factor Surveillance System (BRFSS), was the data source for the cross-sectional study. Smokeless tobacco use and having a dental visit within the previous year were determined from the BRFSS questionnaire. There were 94,821participants included. Chi square and logistic regression analyses were conducted.

Results

There was a significant relationship with smokeless tobacco use and not having a dental visit within the previous year even after adjusting for sex, race/ethnicity, age, education, income, health insurance, smoking, and region. The adjusted odds ratio was 1.42 (95 %CI: 1.17, 1.69; p = 0.0002).

Conclusion

Individuals who use smokeless tobacco products are less likely to have a dental visit within the previous year.

Gambling disorder behaviours, such as one’s preoccupation with gambling and/or mood modification due to gambling, have been proposed to differ in their diagnostic weight/importance, especially when informing diagnostic scales. Such potential differences are imperative to be considered to improve assessment accuracy. The latter is particularly important in the light of the rapidly increasing gambling opportunities offered online. To contribute to this area of knowledge, the current study assessed an online adult community sample (N = 968, M_age = 29.5 years, SD_age = 9.36 years) regarding their responses on the Online Gambling Disorder Questionnaire (OGD-Q). Item response theory (IRT) procedures examined the psychometric properties of the instrument, at both the item and the scale level. Results indicated that the OGD-Q demonstrated good capacity to reliably assess problem gambling and differentiate between individuals at similar levels of the trait, particularly between 1 and 3 SDs above the mean. The findings also showed OGD-Q components/items possess varying discrimination capacities, whilst they also differ in reliability across respondents with different levels of disordered gambling behaviours. Thus, it is supported that consideration is required regarding the differential weighting of one’s item responses in the assessment procedure, taking concurrently into account their severity of disordered gambling behaviours.

Given prevalent alcohol misuse-emotional comorbidities among young adults, we developed an internet-based integrated treatment called Take Care of Me. Although the treatment had an impact on several secondary outcomes, effects were not observed for the primary outcome. Therefore, the goal of the current study was to examine heterogeneity in treatment responses. The initial RCT randomized participants to either a treatment or psychoeducational control condition. We conducted an exploratory latent class analysis to distinguish individuals based on pre-treatment risk and then used moderated regressions to examine differential treatment responses based on class membership. We found evidence for three distinct groups. Most participants fell in the “low severity” group (n = 123), followed by the “moderate severity” group (n = 57) who had a higher likelihood of endorsing a previous mental health diagnosis and treatment and higher symptom severity than the low group. The “high severity” group (n = 42) endorsed a family history of alcoholism, and the highest symptom severity and executive dysfunction. Moderated regressions revealed significant class differences in treatment responses. In the treatment condition, high severity (relative to low) participants reported higher alcohol consumption and hazardous drinking and lower quality of life at follow-up, whereas moderate severity (relative to low) individuals had lower alcohol consumption at follow-up, and lower hazardous drinking at end-of-treatment. No class differences were found for participants in the control group. Higher risk individuals in the treatment condition had poorer responses to the program. Tailoring interventions to severity may be important to examine in future research.
