Validation of the ACSID-11 for consistent screening of specific Internet-use disorders based on ICD-11 criteria for gaming disorder: A multitrait-multimethod approach.

INTRODUCTION: With the inclusion of gaming disorder in the ICD-11, diagnostic criteria were introduced for this relatively new disorder. These criteria may be applied to other potential specific Internet-use disorders. The 11-item Assessment of Criteria for Specific Internet-use Disorders (ACSID-11) was developed for consistent screening of gaming disorder, online buying-shopping disorder, online pornography-use disorder, social networks-use disorder, and online gambling disorder. This study tested the construct validity of the ACSID-11, including convergent and divergent measures. METHODS: The ACSID-11 measures five behavioral addictions with the same set of items by following the principles of the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). The ACSID-11 was administered to a convenience sample of active Internet users (N = 1597) together with validated and established measures of each specific Internet-use disorder along with screeners for mental health. Included are the Ten-Item Internet Gaming Disorder Test (IGDT-10), the Bergen Shopping Addiction Scale (BSAS), the Problematic Pornography Consumption Scale (PPCS), the Bergen Social Media Addiction Scale (BSMAS) and the Berlin Inventory of Gambling behavior - Screening (BIG-S). The ACSID-11 was compared convergently and divergently through a multitrait-multimethod approach along with contingency tables with the other Internet-use disorder screeners. RESULTS: The multitrait-multimethod results shows that each behavior assessed with the ACSID-11 has moderate to strong correlations (r's from 0.462 to 0.609) with the scores of the corresponding established measures and, furthermore, positive correlations (r's from 0.122 to 0.434) with measures of psychological distress and further shows that the ACSID-11 can be used for a comprehensive assessment of different behaviors. The contingency tables reveal large divergences between the ACSID-11 and other screening instruments concerning the classification of problematic specific Internet use based on the given cut-off values. CONCLUSION: The current work provides additional validation for the ACSID-11. Accordingly, this tool can be considered as reliable and valid for the simultaneous assessment of different Internet-use disorders: gaming disorder, online buying-shopping disorder, online pornography use disorder, social networks use disorder, and online gambling disorder. With a subsequent clinical validation of the scale and the proposed cut-off score, the ACSID-11 will be a thoroughly validated useful screening tool for clinical practice.

Symptoms and functional impairments in patients with Internet Use Disorders participating in an online short-term therapy.

BACKGROUND: Internet use disorders (IUD) have been recognized as a serious mental health concern. In order to promote consensus on core features of IUD, further studies involving clinical samples are required. AIMS: A clinical evaluation of patients with IUD was conducted as part of the scientific monitoring of a novel online short-term therapy, embedded in the randomized controlled trial Stepped Care Approach for Problematic Internet use Treatment (SCAPIT; ID: DRKS00025994). METHODS: An online diagnostic and a clinical assessment were performed at the baseline measurement of the online intervention. The self-report version of the Assessment of Internet and Computer Game Addiction (AICA-S) was applied to assess symptom severity of IUD. The impact of psychopathological symptoms and impairments of functioning on IUD symptomatology was examined in the sample of patients. Based on a dichotomous classification of the symptom severity of IUD, differences among participants presenting moderate compared to severe addictive Internet behavior were analyzed. RESULTS: The sample of this an analysis consisted of 57 patients (57.9% males, mean age of 29.12 years) participating in the online short-term therapy for IUD. Based on the AICA-S sum score (M = 11.60; SD = 3.30) participants exhibited moderate (n = 44; 77.2%) to severe (n = 13; 22.8%) symptoms of addictive Internet use. Psychopathological symptoms and impairments of psychosocial functioning had an effect on symptom severity of IUD. Participants with severe symptoms of IUD showed higher psychopathological strains compared to patients with moderate addictive Internet behavior. CONCLUSIONS: The clinical evaluation of patients participating in a novel online short-term therapy for IUD indicated that psychopathological symptoms and impairments of functioning have an impact on addictive Internet behaviors and consequently, need to be addressed in the treatment of IUD. Based on the results, further implications for clinical practice and research on addictive Internet behavior are derived.

Examining the interplay between internet use disorder tendencies and well-being in relation to sofalizing during the COVID-19 pandemic.

AIMS: The present study investigated the potential links between Internet Use Disorder tendencies, well-being and the impact of COVID-19 on Internet usage patterns. METHOD: A sample of 2498 participants filled out the Compulsive Internet Use Scale (CIUS), the Satisfaction with Life Scale (SWLS; the cognitive facet of well-being) and the Sofalizing Scale which comprises the Online Displacement and Social Compensation dimensions. Participants were also asked to report the extent to which changes in Internet use occurred due to COVID-19 pandemic (i.e., reductions, no changes, increases). The present study comprised a survey study with cross-sectional character. RESULTS: The statistical analyses demonstrated that the aforementioned variables were robustly associated with each other. In a first mediation model, the association between higher levels of Internet Use Disorder and reduced well-being was partially mediated by the two dimensions of the Sofalizing scale called Online Displacement and Social Compensation. The results of the second mediation model showed that the relationship between changes in Internet use due to COVID-19 pandemic and well-being was fully mediated by CIUS scores, suggesting that increased Internet use due to the COVID-19 pandemic increased levels of Internet Use Disorder tendencies, which in turn decreased levels of well-being. DISCUSSION: The findings are discussed in the context of human social needs in a time of crisis, where meeting people in-person was restricted.

App-Based Addiction Prevention at German Vocational Schools: Implementation and Reach for a Cluster-Randomized Controlled Trial.

This article examines the implementation, participation rates, and potential determinants of participation in the digital addiction prevention program "ready4life." A two-arm cluster-randomized trial recruited German vocational students via class-based strategies. Intervention group received 16 weeks of in-app coaching; the control group received health behavior information, with coaching offered after 12 months. Potential determinants of participation were analyzed based on class and individual characteristics. Out of 525 contacted schools, 35 participated, enrolling 376 classes. Implementation during the pandemic required flexible adjustments, with 49.7% of introductions conducted in person, 43.1% digitally via online streaming, and 7.2% received a video link via email. Despite challenges, 72.3% of the vocational students downloaded the app, and 46.7% gave informed consent. Participation rates were highest among (associate) professionals, vocational grammar school classes, classes introduced by females, younger individuals, members of the project team, and classes introduced face-to-face. Female gender, lower social competencies, lifetime cannabis use, higher problematic internet use, and higher perceived stress were associated with higher individual participation. The study highlights the importance of proactive outreach and personalized interventions for addiction prevention programs in vocational schools. While reached students aligned with the aims of the app, tailored recruitment strategies could enhance engagement among under-represented groups. The trial was registered in the German Clinical Trials Register (DRKS): DRKS00022328; registration date 09.10.2020.

Internet Use Disorders: Subjective Importance of Online Friends in the Context of Real-Life Social Support and Comorbid Mental Disorders.

INTRODUCTION: Previous studies analyzing friendships with people only known through the Internet mainly focused on quantitative aspects (e.g., the number of online friends or the time spent with them). Little is known about the perceived quality of online compared to real-life friends in individuals with an Internet use disorder (IUD). This study aimed to analyze associations of the increased subjective importance of online friends and IUD by controlling for the perceived real-life social support and comorbid mental disorders. METHODS: Based on a general population sample, 192 participants who were screened positive for risky Internet use took part in face-to-face clinical diagnostic interviews. IUD was assessed using the structure of the Munich-Composite International Diagnostic Interview (M-CIDI) and the adapted criteria of Internet gaming disorder in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The number and the increased subjective importance of online compared to real-life friends were assessed with the Online and Real-Life Friends scale (ORLF), real-life social support was assessed with the Berlin Social Support Scales (BSSS), and comorbidity was assessed with the M-CIDI. Data were analyzed with binary regression models. RESULTS: Of 192 participants with risky Internet use, 39 participants (19 men; age M = 29.9, SD = 12.2) fulfilled the criteria of IUD in the last 12 months. IUD was not associated with the number or perceived social support of online friends per se. In multivariate analyses, IUD was associated with increased subjective importance of online friends, independently from comorbid anxiety or mood disorders. However, when controlling for real-life social support, associations of IUD and increased subjective importance of online friends were no longer present. CONCLUSION: These findings highlight the necessity of therapeutic interventions aimed at strengthening social skills and engaging in real-life relationships in the prevention and therapy of IUD. Due to the small sample size and the cross-sectional analysis, however, further research is needed.

[Children's mental health: the role of screen time, parenting behavior, and parenting stress-a secondary data analysis of KiGGS and BELLA data]. / Mental Health im Kindesalter: der Einfluss von Mediennutzung, Erziehungsverhalten und elterlichem Stresserleben ­ eine Sekundärdatenanalyse von KiGGS- und BELLA-Daten.

BACKGROUND: Previous studies established a link between high screen time and mental health problems in childhood. The role of possible influencing factors is currently unclear. This study aims at testing correlations among mental health problems, high screen time, parenting stress, and inconsistent and positive parenting behavior. METHODS: This study is based on data from the KiGGS and BELLA studies. For the present study, data from preschool children (age: 3-5 years, N = 417) and school children (age: 7-13 years, N = 239) were analyzed. Binary-logistic regressions were carried out to test for correlations between high screen time and children's mental health problems in cross-sectional and longitudinal analyses. Socioeconomic status, the child's gender, the parent's gender, parenting stress, and inconsistent and positive parenting behavior were used as control variables. RESULTS: In the cross-sectional analysis, mental health problems in preschool children were associated with high screen time (OR = 3.02; p = 0.003), parenting stress (OR = 17.00; p < 0.001), and positive parenting behavior (OR = 0.24; p < 0.001). In the longitudinal analysis, mental health problems in school children were associated with parenting stress (OR = 4.04; p < 0.001). Socioeconomic status and the child's and parent's gender were at no point associated with mental health problems. DISCUSSION: The sole existence of high screen time cannot explain mental health problems in children. Parental variables seem to be critical for children's mental health and should be considered in a holistic apporach on children's mental health in terms of strengthening parental competencies.

Advances in problematic usage of the internet research - A narrative review by experts from the European network for problematic usage of the internet.

Global concern about problematic usage of the internet (PUI), and its public health and societal costs, continues to grow, sharpened in focus under the privations of the COVID-19 pandemic. This narrative review reports the expert opinions of members of the largest international network of researchers on PUI in the framework of the European Cooperation in Science and Technology (COST) Action (CA 16207), on the scientific progress made and the critical knowledge gaps remaining to be filled as the term of the Action reaches its conclusion. A key advance has been achieving consensus on the clinical definition of various forms of PUI. Based on the overarching public health principles of protecting individuals and the public from harm and promoting the highest attainable standard of health, the World Health Organisation has introduced several new structured diagnoses into the ICD-11, including gambling disorder, gaming disorder, compulsive sexual behaviour disorder, and other unspecified or specified disorders due to addictive behaviours, alongside naming online activity as a diagnostic specifier. These definitions provide for the first time a sound platform for developing systematic networked research into various forms of PUI at global scale. Progress has also been made in areas such as refining and simplifying some of the available assessment instruments, clarifying the underpinning brain-based and social determinants, and building more empirically based etiological models, as a basis for therapeutic intervention, alongside public engagement initiatives. However, important gaps in our knowledge remain to be tackled. Principal among these include a better understanding of the course and evolution of the PUI-related problems, across different age groups, genders and other specific vulnerable groups, reliable methods for early identification of individuals at risk (before PUI becomes disordered), efficacious preventative and therapeutic interventions and ethical health and social policy changes that adequately safeguard human digital rights. The paper concludes with recommendations for achievable research goals, based on longitudinal analysis of a large multinational cohort co-designed with public stakeholders.

Addiction Research Unit: Affective and cognitive mechanisms of specific Internet-use disorders.

In the eleventh International Classification of Diseases (ICD-11) of the World Health Organization, gambling disorder and gaming disorder are included in the category 'disorders due to addictive behaviours', which can be specified further as occurring either predominantly offline or predominantly online. Other specific problematic behaviours may be considered for the category 'other specified disorders due to addictive behaviours'. The Research Unit FOR 2974, funded by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG), focuses on the most prominent online addictive behaviours: gaming, pornography use, buying-shopping and social-networks use. The main goal of the Research Unit is to contribute to a better understanding of the common and differential psychological as well as neurobiological mechanisms involved in these specific types of Internet-use disorders. We aim to investigate theoretically argued (bio)psychological processes with a focus on concepts coming from research of substance-use disorders, for example, cue reactivity and craving, executive functions and specific inhibitory control, coping, implicit cognitions, and decision making. One central characteristic of the Research Unit is that we will investigate all participants using a comprehensive core battery of experimental paradigms, neuropsychological tasks, questionnaires, biomarkers, ambulatory assessment, and a 6-month follow-up survey. Beyond the anticipated contributions to the scientific understanding of the mechanisms involved in the development and maintenance of respective online addictive behaviours, we also expect contributions to clinical practice by showing which affective and cognitive mechanisms may be addressed more intensively to optimize treatment.

Association of Increased Impulsiveness and Internet Use Disorder in Adolescents and Young Adults with Different Main Activities on the Internet.

Objective: Increased impulsiveness is a risk factor for health-endangering behavior patterns. Little is known about whether increased impulsiveness is associated with Internet Use Disorder (IUD) and whether individuals with various main activities on the internet differ in their levels of impulsiveness. Methods: In total, we screened 8,230 vocational students for problematic internet use with the Compulsive Internet Use Scale (CIUS). Participants scoring at least 21 points in the CIUS took part in an in-depth diagnostic interview. IUD was assessed according to the criteria of Internet Gaming Disorder (IGD) as suggested in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Impulsiveness was assessed with the Barratt Impulsiveness Scale (BIS-15). We analyzed the data using binary logistic regression models and nonparametric tests. Results: Participants with IUD (n = 144) showed increased impulsiveness (p = .005) compared to those without IUD (n = 774). Participants with different main activities on the internet did not differ in their levels of impulsiveness. Conclusions: Results indicate that impulsiveness is associated with IUD, independent of the main internet activity. This highlights the necessity to consider patients' impulsiveness in prevention and therapeutic approaches. Because of the cross-sectional study design, further research with longitudinal study designs is needed.

Preventing problematic internet use during the COVID-19 pandemic: Consensus guidance.

As a response to the COVID-19 pandemic, many governments have introduced steps such as spatial distancing and "staying at home" to curb its spread and impact. The fear resulting from the disease, the 'lockdown' situation, high levels of uncertainty regarding the future, and financial insecurity raise the level of stress, anxiety, and depression experienced by people all around the world. Psychoactive substances and other reinforcing behaviors (e.g., gambling, video gaming, watching pornography) are often used to reduce stress and anxiety and/or to alleviate depressed mood. The tendency to use such substances and engage in such behaviors in an excessive manner as putative coping strategies in crises like the COVID-19 pandemic is considerable. Moreover, the importance of information and communications technology (ICT) is even higher in the present crisis than usual. ICT has been crucial in keeping parts of the economy going, allowing large groups of people to work and study from home, enhancing social connectedness, providing greatly needed entertainment, etc. Although for the vast majority ICT use is adaptive and should not be pathologized, a subgroup of vulnerable individuals are at risk of developing problematic usage patterns. The present consensus guidance discusses these risks and makes some practical recommendations that may help diminish them.

Can brief alcohol interventions in general hospital inpatients improve mental and general health over 2 years? Results from a randomized controlled trial.

BACKGROUND: Little is known about the impact of brief alcohol interventions on mental and general health. The aim was to investigate whether brief interventions for general hospital inpatients with at-risk drinking can improve mental and general health over 2 years; and whether effects are dependent on how they are delivered: in-person or through computer-generated feedback letters (CO). METHODS: Three-arm randomized controlled trial with 6-, 12-, 18-, and 24-month follow-ups. Data were collected on 13 general hospital wards from four medical departments (internal medicine, surgical medicine, trauma surgery, and ear-nose-throat) of one university hospital in northeastern rural Germany. A consecutive sample of 961 18- to 64-year-old general hospital inpatients with at-risk alcohol use was recruited through systematic screening. Inpatients with particularly severe alcohol problems were excluded. Participants were allocated to: in-person counseling (PE), CO, and assessment only (AO). PE and CO included three contacts: on the ward, 1, and 3 months later. Mental and general health were assessed using the five-item mental health inventory (0-100) and a one-item general health measure (0, poor - 4, excellent). RESULTS: Latent growth models including all participants revealed: after 24 months and in contrast to AO, mental and general health were improved in PE (change in mean difference, ΔMmental = 5.13, p = 0.002, Cohen's d = 0.51; ΔMgeneral = 0.20, p = 0.005, d = 0.71) and CO (ΔMmental = 6.98, p < 0.001, d = 0.69; ΔMgeneral = 0.24, p = 0.001, d = 0.86). PE and CO did not differ significantly. CONCLUSIONS: Beyond drinking reduction, PE and CO can improve general hospital inpatients' self-reported mental and general health over 2 years.

Feasibility and Acceptability of an Intervention Providing Computer-Generated Tailored Feedback to Target Alcohol Consumption and Depressive Symptoms in Proactively Recruited Health Care Patients and Reactively Recruited Media Volunteers: Results of a Pilot Study.

BACKGROUND: A pre-post pilot study was conducted to test the feasibility, acceptability, and potential effectiveness of a fully automatized computer-based intervention targeting hazardous drinking and depressiveness in proactively recruited health care patients (HCPs). To address the importance of the sample selection when testing interventions, HCPs were compared to media recruited volunteers (MVs). METHOD: In a multicenter screening program 2,773 HCPs were screened for hazardous drinking and depressive symptoms. MVs were recruited via media solicitation. Over a period of 6 months, study participants received 6 individualized counseling letters and weekly short messages. Pre-post data were analyzed for 30 participants (15 HCPs, 15 MVs). Intervention acceptability was assessed in post-intervention interviews conducted with 32 study participants. RESULTS: MVs showed higher problem severity and motivation to change than HCPs. Over the course of the intervention both subsamples reduced regular binge drinking (HCPs: p = 0.016; MVs: p = 0.031) and depressiveness (HCPs: p = 0.020; MVs: p < 0.001). MVs further reduced average daily alcohol consumption (p = 0.034). The intervention received positive ratings from both subsamples, the alcohol module was rated more favorably by MVs than by HCPs (p = 0.012). Subsamples further differed in terms of intervention usage (p = 0.013). CONCLUSION: The intervention was technically and logistically feasible, well accepted, and may have the potential to reduce hazardous drinking and depressive symptoms in different populations. Subsamples differed in terms of problem severity, motivation to change, intervention usage, pre-post changes, and attitudes toward the intervention, showing that intervention development should involve the intended target populations to avoid biased conclusions on intervention effectiveness and acceptability.

Screening for Hazardous Drinking in Nursing Home Residents: Evaluating the Validity of the Current Cutoffs of the Alcohol Use Disorder Identification Test-Consumption Questions by Using Ethyl Glucuronide in Hair.

BACKGROUND: Because of physiological changes, elderly people are much more exposed to the adverse effects of alcohol. Therefore, hazardous drinking is defined at lower levels as compared to younger adults. This work aimed to evaluate the validity of the current cutoff levels of the Alcohol Use Disorder Identification Test-Consumption (AUDIT-C) questions to detect hazardous drinking in the elderly by using ethyl glucuronide in hair (HEtG). METHODS: In a border region between Austria and Germany, 344 nursing home residents were included from 33 of the 107 nursing homes. Residents were asked to answer the AUDIT-C questions, hair samples were obtained, and nursing staff members were asked for their assessments of the residents' alcohol consumption. Hair samples were analyzed for HEtG using gas chromatography-mass spectrometry. Receiver-operating characteristic (ROC) curve analysis was performed to determine the validity of cutoff values for the AUDIT-C to detect an alcohol consumption of ≥10 g of alcohol/d. RESULTS: A total of 11.3% of the nursing home residents (n = 344) drank ≥10 g of alcohol/d (4.9% >60 g of alcohol/d, 6.4% 10 to 60 g of alcohol/d, 88.7% <10 g of alcohol/d)). For the drinking limit of ≥10 g of alcohol/d, ROC curve analysis showed a balanced sensitivity and specificity, with an AUDIT-C cutoff of ≥4 for men (sensitivity: 70%, specificity: 83.6%; AUC = 0.823, CI = 0.718 to 0.928, p < 0.001) and ≥2 for women (sensitivity: 73.7%, specificity: 81.9%; AUC = 0.783, CI = 0.653 to 0.914, p < 0.001). Nursing staff (n = 274) underestimated alcohol consumption and evaluated 40% of the chronic-excessive alcohol consumers (>60 g of alcohol/d) as being abstinent. CONCLUSIONS: Our data suggest that an AUDIT-C cutoff of ≥4 for men and ≥2 for women can be recommended to detect the consumption of ≥10 g of alcohol/d in the elderly. Because the nursing staff to a large extent underestimates the alcohol consumption among nursing home residents, further teaching of the staff, improvement of screening instruments for the elderly, and the use of objective biomarkers might be helpful for recognizing hazardous drinking and can thus help improve the quality of life of the elderly.

Demographic Risk Factors and Gambling Preference May Not Explain the High Prevalence of Gambling Problems Among the Population with Migration Background: Results from a German Nationwide Survey.

There are high proportions of problem gamblers among individuals who themselves or whose parents immigrated to Germany. This study aimed to examine whether demographic risk factors and gambling preference may explain the higher prevalence of gambling problems among those with migration background (MB). Data was obtained from a nationwide telephone survey which was part of the project "Pathological Gambling and Epidemiology" (PAGE). The sample comprised 15,023 study participants aged 14-64 years living in Germany. Participants who had reported gambling within their lifetime (n = 6,406) were defined as gamblers and categorized according to their MB (n = 1,209 with MB), additional demographic characteristics (sex, age, marital status, household size, education, occupation), preferred types of gambling (21 categories covering the gambling types available in Germany), and the count of lifetime gambling problem symptoms (0-10 criteria of the fourth Diagnostic and Statistical Manual of Mental Disorders). Estimates from a negative binomial regression revealed that there is a 146.2% increase in the expected count of gambling problem symptoms for gamblers with MB compared to those without MB. The percentage decreased to 102.5 and 97.6% after adjustment for demographic characteristics and further adjustment for preferred types of gambling, respectively. Demographic risk factors and gambling preference may partially mediate but not completely explain the higher prevalence of gambling problems among the population with MB. Having an MB may be considered as an independent risk factor for gambling problems, which indicates a need for culturally sensitive prevention and treatment measures.

Occurence of internet addiction in a general population sample: a latent class analysis.

BACKGROUND: Prevalence studies of Internet addiction in the general population are rare. In addition, a lack of approved criteria hampers estimation of its occurrence. AIMS: This study conducted a latent class analysis (LCA) in a large general population sample to estimate prevalence. METHODS: A telephone survey was conducted based on a random digit dialling procedure including landline telephone (n=14,022) and cell phone numbers (n=1,001) in participants aged 14-64. The Compulsive Internet Use Scale (CIUS) served as the basis for a LCA used to look for subgroups representing participants with Internet addiction or at-risk use. CIUS was given to participants reporting to use the Internet for private purposes at least 1 h on a typical weekday or at least 1 h on a day at the weekend (n=8,130). RESULTS: A 6-class model showed best model fit and included two groups likely to represent Internet addiction and at-risk Internet use. Both groups showed less social participation and the Internet addiction group less general trust in other people. Proportions of probable Internet addiction were 1.0% (CI 0.9-1.2) among the entire sample, 2.4% (CI 1.9-3.1) in the age group 14-24, and 4.0% (CI 2.7-5.7) in the age group 14-16. No difference in estimated proportions between males and females was found. Unemployment (OR 3.13; CI 1.74-5.65) and migration background (OR 3.04; CI 2.12-4.36) were related to Internet addiction. CONCLUSIONS: This LCA-based study differentiated groups likely to have Internet addiction and at-risk use in the general population and provides characteristics to further define this rather new disorder.

Behavior-related risk factors and time to death among persons with alcohol consumption versus persons without: A general population study with mortality follow-up after 20 years.

BACKGROUND: Evidence shows that low to moderate alcohol consumers seem to live longer than abstainers. Insufficient consideration of subgroups among abstainers and of further behavior-related risk factors for death might be reasons. The aim of this study was to compare alcohol lifetime abstainers, former drinkers, and current consumers with regard to mortality considering tobacco smoking, body overweight, and physical inactivity. METHODS: A general adult population sample of residents aged 18 to 64 had been drawn at random in northern Germany. Among eligible persons, 4093 (70.2%) participated. Assessments included alcohol consumption by the Alcohol Use Disorders Identification Test Consumption in addition to lifetime alcohol abstinence and former drinking. A score of behavior-related risk factors was built from tobacco smoking, body overweight, and physical inactivity. Twenty years later, a mortality follow-up was conducted. Data of 4028 study participants were analyzed. RESULTS: At baseline, former alcohol consumers but not current low to moderate alcohol drinkers had more behavior-related risk factors than lifetime abstainers. At follow-up, former alcohol drinkers with two or more behavior-related risk factors had a shorter time to death than lifetime abstainers with 0 or one behavior-related risk factor (hazard ratio 3.43, 95% confidence interval: 1.63-7.20). Low to moderate alcohol drinkers did not survive longer than lifetime alcohol abstainers with 0 or one behavior-related risk factor. CONCLUSION: The results provide evidence against the assumption that alcohol consumption has a beneficial effect on health and longevity.

Investigating the interplay between gaming disorder and functional impairments in professional esports gaming.

The relationship between Gaming Disorder (GD) and the experience of functional impairments has received considerable theoretical attention in the recent past and current diagnostic approaches underscore the centrality of functional impairments as a requirement for GD diagnosis. However, there is limited empirical evidence illuminating the interplay between GD and functional impairments, particularly among specific vulnerable groups. The present study seeks to bridge this gap by investigating an English-speaking sample (N = 5198) comprising an age- and gender-matched group of Professional Gamers (PG, n = 2599) and Non-Professional Gamers (NPG, n = 2599) sub-sampled from a larger sample of 192,260 individuals. The results revealed that PG were at a greater risk for GD compared to NPG as the prevalence rate of GD among PG (3.31%) was significantly higher and almost doubled that of NPG (1.73%), with PG further exhibiting higher overall GD symptom-load and weekly time spent gaming compared to NPG. Furthermore, PG reported experiencing significantly higher frequency of gaming-related functional impairments compared to NPG, with the in particular affected areas for both PG and NPG being 'school and/or work', 'physical health', and 'family', with other key differences emerging in relation to other outcomes. Overall, the present findings show that not only GD symptom-load but also some functional impairment is higher in PG compared to NPG which highlights the need to develop and support prevention and intervention strategies for this at-risk population.

Insights on associations between the frequency of use of diverse social media products and social networks use disorder tendencies from a German speaking sample.

OBJECTIVE: In the present work we investigate how individual differences in at least occasionally using distinct social media platforms is linked to social networks use disorder (SNUD) tendencies. A final sample of n = 2200 participants filled in the AICA-C-9 measure to get insights into individual differences in overuse of social media and participants also indicated which platforms they used at least once a month. RESULTS: The analysis revealed a robust positive association between number of at least occasionally used social media apps and SNUD tendencies (r = .44, p < .001). Further, platforms differed in terms of their "addictive potential", if one takes associations between frequency of distinct platforms use and SNUD tendencies as a proxy for this (and of course the actual descriptive statistics of the SNUD scale for the (non-)frequent user groups of the different platforms). In this regard, at least occasionally using some platforms (here Tumblr, Twitter and TikTok) was associated with highest SNUD tendencies. Moreover, largest differences in terms of effect sizes between the occasional and non-occasional user groups regarding SNUD scores could be observed for Instagram, WhatsApp, and TikTok. The present work bases on data from a larger project investigating associations between SNUD and tobacco use disorder.

Problematic social media use in childhood and adolescence.

At the time of writing, about 4.59 billion people use social media with many adolescents using their social media accounts across a myriad of applications and platforms. According to recent statistics, in 2022 individuals spent an average of 151 minutes on social media each day, illustrating the global relevance of social media (Dixon, 2022a,b). One of the pressing questions, internationally, is whether social media use is harmful and/or addictive. This question is of particular importance because many teenagers - and younger adolescents - spend considerable time on these platforms, which have increasingly become an integral part of their lives. Moreover, considering lifespan development, adolescents may be particularly vulnerable to specific features and advertisements shown to them on social media platforms. Growing prevalence of poor mental health in young people has led to recent recommendations in the United States to routinely screen for anxiety in 8-18 year olds, and for depression and suicide risk for adolescents between 12-18 years of age (US Preventive Services Task Force et al., 2022 a,b) - the conditions often accompanying problematic social media use. The present work not only provides insights into the current state of the literature but provides also recommendations.

An International, Multidisciplinary Consensus Set of Patient-Centered Outcome Measures for Substance-Related and Addictive Disorders.

Background: In 1990, the United States' Institute of Medicine promoted the principles of outcomes monitoring in the alcohol and other drugs treatment field to improve the evidence synthesis and quality of research. While various national outcome measures have been developed and employed, no global consensus on standard measurement has been agreed for addiction. It is thus timely to build an international consensus. Convened by the International Consortium for Health Outcomes Measurement (ICHOM), an international, multi-disciplinary working group reviewed the existing literature and reached consensus for a globally applicable minimum set of outcome measures for people who seek treatment for addiction. Methods: To this end, 26 addiction experts from 11 countries and 5 continents, including people with lived experience (n = 5; 19%), convened over 16 months (December 2018-March 2020) to develop recommendations for a minimum set of outcome measures. A structured, consensus-building, modified Delphi process was employed. Evidence-based proposals for the minimum set of measures were generated and discussed across eight videoconferences and in a subsequent structured online consultation. The resulting set was reviewed by 123 professionals and 34 people with lived experience internationally. Results: The final consensus-based recommendation includes alcohol, substance, and tobacco use disorders, as well as gambling and gaming disorders in people aged 12 years and older. Recommended outcome domains are frequency and quantity of addictive disorders, symptom burden, health-related quality of life, global functioning, psychosocial functioning, and overall physical and mental health and wellbeing. Standard case-mix (moderator) variables and measurement time points are also recommended. Conclusions: Use of consistent and meaningful outcome measurement facilitates carer-patient relations, shared decision-making, service improvement, benchmarking, and evidence synthesis for the evaluation of addiction treatment services and the dissemination of best practices. The consensus set of recommended outcomes is freely available for adoption in healthcare settings globally.
