Background: Objective diagnostic approaches need to be tested to enhance the efficacy of depression detection. Non-invasive EEG-based identification represents a promising area., Aims: The present EEG study addresses two central questions: 1) whether inner or overt speech condition result in higher diagnositc accuracy of depression detection; and 2) does the affective nature of the presented emotion words count in such diagnostic approach., Methods: A matched case-control sample consisting of 10 depressed subjects and 10 healthy controls was assessed. An EEG headcap containing 64 electrodes measured neural responses to experimental cues presented in the form of 15 different words that belonged to three emotional categories: neutral, positive, and negative. 120 experimental cues was presented for every participant, each containing an "inner speech" and an "overt speech" segment. An EEGNet neural network was utilized., Results: The highest diagnostic accuracy of the EEGNet model was observed in the case of the overt speech condition (i.e. 69.5%), while a an overall subject-wise accuracy of 80% was achieved by the model. Only a negligible difference in diagnostic accuracy could be found between aggregated emotion word categories, with the highest accuracy (i.e. 70.2%) associated with the presentation of positive emotion words. Model decision was primarily influenced by electrodes representing the regions of the left parietal, the left temporal lobe and the middle frontal areas., Conclusions: While the generalizability of our results is limited by the small sample size and potentially uncontrolled confounders, depression was associated with sensitive and presumably network-like aspects of these brain areas, potentially implying a higher level of emotion regulation that increases primarily in open communication., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Background: With the increase of cyberbullying, several intervention programmes have been created that aim at reducing cyber-victimisation and perpetration., Objective: Our study presents the effects of the STAnD anti-cyberbullying programme with peer-education both on the short and the long run among lower and upper primary school students, with a focus on the participants' cyberbullying roles., Method: The sample comprised of 536 students who participated in the intervention programme, involving 36% lower and 64% upper primary school students. Participants were measured by a self-reported questionnaire before and right after the programme, then six months later., Results: The main effect of the STAnD programme was a positive change in the participants' willingness to engage in help-seeking and their active-defending reaction, although this effect decreased after six months. The changes were larger among lower primary school students compared to upper primary school participants., Conclusion: Our results imply that long-lasting and intensive health promotion programmes are necessary to reach a long-term intervention effect. Anti-cyberbullying programmes should take into consideration participants' involvement and roles in cyberbullying. As our study was a non-randomised uncontrolled study design, thus interpretation of the effectiveness of the programme is limited., Supplementary Information: The online version contains supplementary material available at 10.1007/s10566-022-09714-9., Competing Interests: Conflict of interestThe authors have no relevant financial or non-financial interests to disclose., (© The Author(s) 2022.)

Objective: This study aims to assess the validity of the ADHD module of the Mini-International Neuropsychiatric Interview (MINI-Plus) in patients with substance use disorders (SUD), using the Conners' Adult ADHD Diagnostic Interview for DSM-IV (CAADID) as the external criterion., Method: A cross sectional international multi-center study in 10 countries was conducted in treatment seeking SUD patients. A sample of 1263 patients with both MINI-Plus and CAADID was analyzed to determine the psychometric properties of the MINI-Plus., Results: According to the CAADID, 179 patients (14.2%) met criteria for adult ADHD, whereas according to the MINI-Plus 227 patients (18.0%) were identified as having adult ADHD. Sensitivity of the MINI-Plus ADHD module was 74%, specificity was 91%, positive predictive value was 60% and negative predictive value was 96%. Kappa was 0.60., Conclusion: The MINI-Plus has acceptable criterion validity for the screening of adult ADHD in treatment seeking SUD patients., Scientific Significance: On the basis of the results, The MINI-Plus may be used for the screening of ADHD in SUD patients., (Copyright © 2020 The Author(s).

Background: Time perception and motion intensity are interrelated factors that may influence symptom expression and severity in case of various psychiatric conditions, including anxiety and depression., Aims: The present study aimed to 1) explore the associations between the intensity of physical activity, time perception, impulsivity, anxiety and depressive symptoms, and to 2) investigate the extent to which resting state motion intensity can be used to identify the assessed psychiatric conditions., Methods: 20 healthy controls and 20 psychiatric patients (with either anxiety or depression-related diagnoses) were included in the study and filled out a questionnaire consisting of validated anxiety, depression and impulsivity measures. Time perception was measured by a computerized time production task, whereas motion intensity was analyzed by a motion capture and analysis software. Respondents were randomly assigned to an experimental (with active motion task) and non-experimental group (resting state conditions). Both subgroups were repeatedly assessed, in order to explore changes in motion intensity, time perception and psychiatric symptom levels., Results: Random forest regression analysis identified the level of impulsivity, depression and anxiety as the strongest predictors of resting state motion intensity, while a path analysis model indicated that controls and psychiatric patients show different pathways regarding the connection between motion intensity changes, time production ratio alterations and symptom reduction., Conclusions: Our study implies the importance of distinguishing between clinical and subclinical severity of psychiatric symptoms when considering the association between motion intensity, time perception, anxiety and depression. Potential transdiagnostic relevance of resting state motion intensity is also addressed., Competing Interests: Declaration of competing interest Authors declare no conflict of interest., (Copyright © 2022 The Authors.

Background: Substance use disorders (SUD) often co-occur with attention deficit hyperactivity disorder (ADHD). Although the short-term effects of some specific interventions have been investigated in randomized clinical trials, little is known about the long-term clinical course of treatment-seeking SUD patients with comorbid ADHD., Aims: This paper presents the protocol and baseline clinical characteristics of the International Naturalistic Cohort Study of ADHD and SUD (INCAS) designed and conducted by the International Collaboration on ADHD and Substance Abuse (ICASA) foundation. The overall aim of INCAS is to investigate the treatment modalities provided to treatment-seeking SUD patients with comorbid ADHD, and to describe the clinical course and identify predictors for treatment outcomes. This ongoing study employs a multicentre observational prospective cohort design. Treatment-seeking adult SUD patients with comorbid ADHD are recruited, at 12 study sites in nine different countries. During the follow-up period of nine months, data is collected through patient files, interviews, and self-rating scales, targeting a broad range of cognitive and clinical symptom domains, at baseline, four weeks, three months and nine months., Results: A clinically representative sample of 578 patients (137 females, 441 males) was enrolled during the recruitment period (June 2017-May 2021). At baseline, the sample had a mean age (SD) of 36.7 years (11.0); 47.5% were inpatients and 52.5% outpatients; The most prevalent SUDs were with alcohol 54.2%, stimulants 43.6%, cannabis 33.1%, and opioids 14.5%. Patients reported previous treatments for SUD in 71.1% and for ADHD in 56.9%. Other comorbid mental disorders were present in 61.4% of the sample: major depression 31.5%, post-traumatic stress disorder 12.1%, borderline personality disorder 10.2%., Conclusions: The first baseline results of this international cohort study speak to its feasibility. Data show that many SUD patients with comorbid ADHD had never received treatment for their ADHD prior to enrolment in the study. Future reports on this study will identify the course and potential predictors for successful pharmaceutical and psychological treatment outcomes., Trial Registration: ISRCTN15998989 20/12/2019., (© 2022.

International Consensus Statement for the Screening, Diagnosis, and Treatment of Adolescents with Concurrent Attention-Deficit/Hyperactivity Disorder and Substance Use Disorder Abstract. Background: Childhood attention-deficit/hyperactivity disorder (ADHD) is a risk factor for substance misuse and substance use disorder (SUD) in adolescence and (early) adulthood. ADHD and SUD also frequently co-occur in treatment-seeking adolescents, which complicates diagnosis and treatment and is associated with poor treatment outcomes. Research on the effect of treatment of childhood ADHD on the prevention of adolescent SUD is inconclusive, and studies on the diagnosis and treatment of adolescents with ADHD and SUD are scarce. Thus, the available evidence is generally not sufficient to justify robust treatment recommendations. Objective: The aim of the study was to obtain a consensus statement based on a combination of scientific data and clinical experience. Method: A modified Delphi study to reach consensus based upon the combination of scientific data and clinical experience with a multidisciplinary group of 55 experts from 17 countries. The experts were asked to rate a set of statements on the effect of treatment of childhood ADHD on adolescent SUD and on the screening, diagnosis, and treatment of adolescents with comorbid ADHD and SUD. Results: After 3 iterative rounds of rating and adapting 37 statements, consensus was reached on 36 of these statements representing 6 domains: general ( n = 4), risk of developing SUD ( n = 3), screening and diagnosis ( n = 7), psychosocial treatment ( n = 5), pharmacological treatment ( n = 11), and complementary treatments ( n = 7). Routine screening is recommended for ADHD in adolescent patients in substance abuse treatment and for SUD in adolescent patients with ADHD in mental healthcare settings. Long-acting stimulants are recommended as the first-line treatment of ADHD in adolescents with concurrent ADHD and SUD, and pharmacotherapy should preferably be embedded in psychosocial treatment. The only remaining no-consensus statement concerned the requirement of abstinence before starting pharmacological treatment in adolescents with ADHD and concurrent SUD. In contrast to the majority, some experts required full abstinence before starting any pharmacological treatment, some were against the use of stimulants in the treatment of these patients (independent of abstinence), while some were against the alternative use of bupropion. Conclusion: This international consensus statement can be used by clinicians and patients together in a shared decision-making process to select the best interventions and to reach optimal outcomes in adolescent patients with concurrent ADHD and SUD.

Objective: The efficacy of alcohol reduction applications is variable, and the underlying factors are largely unknown. The aim of this study is threefold: evaluate the relationship between user engagement and intervention efficacy, investigate the efficacy of the different functions applied, and investigate the efficacy of the intervention application compared to control groups., Methods: A randomized controlled trial will be conducted to determine the efficacy of a newly developed smartphone application compared to the controls in reducing alcohol consumption at a 30, 60, 90, 120, 150, and 180 days follow-up. Hazardous drinkers, aged 18 years or older, will be recruited through web articles and will be randomized (blinded to their allocation), to receive one of the two versions of the application (educational or control application) for 30 days, or will be allocated to a wait-list control group. Function usage times will be recorded on a single-user level to determine the association between application usage and efficacy., Results: Data collection will be completed by July 2020, and follow-up will be completed by January 2021., Conclusions: The evaluation of intervention efficacy as a function of user behavior will hopefully contribute to the science of developing more efficient alcohol intervention applications in the future., (© 2020 The Authors.

Introduction: New psychoactive substances (NPS) pose a public health threat. Many studies have tried to identify the reasons of NPS use; however, none of them have so far used any standardised measures. The aim of this study was (i) to develop and cross-culturally validate the New Psychoactive Substance Use Motives Measure (NPSMM) and (ii) to compare motives of NPS use across countries and user types., Methods: Three subgroups (socially marginalised users, nightlife attendees and members of online communities) of NPS users ( N = 3023) were recruited from six EU member countries. Demographics, motives and types of NPS used were assessed. NPS use motives were measured by adapting the extended six-factor version of the Marijuana Motives Measure., Results: Exploratory and confirmatory factor analysis resulted in a similar five-factor solution across most of the countries: coping, enhancement, social, conformity and expansion motives. Marginalised users scored higher on coping and conformity motives, nightlife groups showed higher endorsement of social motive, whereas online community users showed higher scores on expansion motives. Various types of NPS were also associated with different motives., Conclusion: NPS use motives might be associated with both the groups of users and the specific types of NPS being consumed. Expansion (psychedelics) and enhancement (stimulants) motives seemed to be linked to the chosen NPS product type, while coping, social and conformity motives were rather associated with user groups. NPSMM was found to be a valid instrument to measure NPS motives.

Background and Aims: Due to its important role in both healthy groups and those with physical, mental and behavioral disorders, impulsivity is a widely researched construct. Among various self-report questionnaires of impulsivity, the Barratt Impulsiveness Scale is arguably the most frequently used measure. Despite its international use, inconsistencies in the suggested factor structure of its latest version, the BIS-11, have been observed repeatedly in different samples. The goal of the present study was therefore to test the factor structure of the BIS-11 in several samples., Methods: Exploratory and confirmatory factor analyses were conducted on two representative samples of Hungarian adults (N = 2,457; N = 2,040) and a college sample (N = 765)., Results: Analyses did not confirm the original model of the measure in any of the samples. Based on explorative factor analyses, an alternative three-factor model (cognitive impulsivity; behavioral impulsivity; and impatience/restlessness) of the Barratt Impulsiveness Scale is suggested. The pattern of the associations between the three factors and aggression, exercise, smoking, alcohol use, and psychological distress supports the construct validity of this new model., Discussion: The new measurement model of impulsivity was confirmed in two independent samples. However, it requires further cross-cultural validation to clarify the content of self-reported impulsivity in both clinical and nonclinical samples.

Background: With a decrease in heroin's purity and availability in the European drug market, Hungarian opioid dependent patients started to substitute heroin with novel psychoactive substances (NPS) and especially with synthetic cathinones., Goal: This study aims to assess whether clients of opioid substitution treatment (OST) with and without a history of synthetic cathinone use during therapy differ in (1) the rate and type of experienced childhood trauma, (2) the way they cope with negative life events, (3) their motivation to change substance use behavior, (4) the rate of treatment retention., Methods: A total of 198 clients of an outpatient centers (Nyírõ Gyula National Institute of Psychiatry and Addictions, Budapest) OST were asked to provide information about their general substance use experiences, including the consumption of NPS during treatment, their childhood traumatic experiences (Childhood Trauma Questionnaire), cognitive emotion regulation strategies (Cognitive Emotion Regulation Questionnaire), their motivation to change substance use behavior (University of Rhode Island Change Assessment Scale) and current psychiatric symptoms (Brief Symptom Inventory). Baseline data was collected in the summer of 2015, while 4 years follow-up data on treatment retention was obtained in the summer of 2019., Results: The majority of the clients were male ( N = 141, 71.2%), receiving methadone as a substitute for opioids ( N = 178, 89.9%), while mean age of the full sample was 39.7 (SD = 6.8). Based on a logistic regression model, the odds for past year synthetic cathinone use was higher among clients with more severe psychiatric symptoms ( B = 0.8, OR = 2.2, p < 0.01) and among clients who were in treatment for a shorter period of time ( B = 0.1, OR = 0.9, p < 0.05). Synthetic cathinone use during treatment was further associated with less adaptive strategies to cope with negative life events. Synthetic cathinone use was also a risk factor for reduced treatment retention ( B = -0.8, OR = 0.4, p < 0.05) and was associated with lower odds of being member of a latent class with less severe psychopathological profile ( B = -0.9, OR = 0.4, p < 0.05)., Conclusion: Synthetic cathinone use during treatment is associated with poorer treatment outcomes and might be characterized by more severe psychiatric symptoms and amotivation to change substance use among opioid dependent clients., (Copyright © 2020 Kapitány-Fövény, Kiss, Farkas, Kuczora, Pataki, Horváth and Demetrovics.)

Background: Although substance use disorders (SUD) and attention-deficit/hyperactivity disorder (ADHD) show significant symptomatic overlap, ADHD is often overlooked in SUD patients., Objective: The aim of the present study was to characterize aspects of attention and inhibition (as assessed by a continuous performance test [CPT]) in SUD patients with and without a comorbid diagnosis of ADHD and in healthy controls, expecting the most severe deficits in patients with a combined diagnosis., Methods: The MOXO-CPT version, which incorporates visual and auditory environmental distractors, was administered to 486 adults, including healthy controls (n = 172), ADHD (n = 56), SUD (n = 150), and combined SUD and ADHD (n = 108)., Results: CPT performance of healthy controls was better than that of individuals in each of the 3 clinical groups. The only exception was that the healthy control group did not differ from the ADHD group on the Timing index. The 3 clinical groups differed from each other in 2 indices: (a) patients with ADHD (with or without SUD) showed increased hyperactivity compared to patients with SUD only and (b) patients with ADHD showed more responses on correct timing as compared with the SUD groups (with or without ADHD)., Conclusion: The CPT is sensitive to ADHD-related deficits, such as disinhibition, poor timing, and inattention, and is able to consistently differentiate healthy controls from patients with ADHD, SUD, or both. Our results are in line with previous research associating both ADHD and SUD with multiple disruptions across a broad set of cognitive domains such as planning, working memory, decision-making, inhibition control, and attention. The lack of consistent differences in cognitive performance between the 3 diagnostic groups might be attributed to various methodological aspects (e.g., heterogeneity in severity, type, and duration of substances use). Our results support the view that motor activity should be considered a significant marker of ADHD., (© 2020 S. Karger AG, Basel.)

Data generated through public Internet searching offers a promising alternative source of information for monitoring and forecasting of infectious disease. Here future cases of tick-borne encephalitis (TBE) were predicted using traditional weekly case reports, both with and without Google Trends data (GTD). Data on the weekly number of acute, confirmed TBE cases in Germany were obtained from the Robert Koch Institute. Data relating to the volume of Internet searching on TBE was downloaded from the Google Trends website. Data were split into training and validation parts. A SARIMA (0,1,1) (1,1,1) [52] model was used to describe the weekly TBE case number time series. Google Trends Data was used as an external regressor in a second, as optimal identified SARIMA (4,1,1) (1,1,1) [52] model. Predictions for the number of future cases were made with both models and compared with the validation dataset. GTD showed a significant correlation with reported weekly case numbers of TBE (p < 0.0001). A comparison of forecasted values with reported ones resulted in an RMSE (residual mean squared error) of 0.71 for the model without Google search values, and an RMSE of 0.70 for the Google Trends values enhanced model. However, difference between predictive performances was not significant (Diebold Mariano test, p-value = 0.14)., (Copyright © 2019 Elsevier GmbH. All rights reserved.)

Background : Temporary abstinence from alcohol as a challenge could support self-knowledge, self-care, and health consciousness in several ways. Objectives : The present study explored Dry November participants' personal experiences and coping strategies during a one-month abstinence period. The research is embedded in the Hungarian context of drinking habits, culture, society, and alcohol policy. Methods : This qualitative study comprised the thematic analysis of 23 participants' diaries, reported twice a week for 30 days (in November 2017), to identify and understand the common experiences of temporary sobriety. Results : Three main themes emerged from the analysis: challenge, community, and relationship toward alcohol and abstinence . Results showed that there are no categorical differences between successful and non-successful participants. Conclusions : The present research demonstrated that during the challenge, rather than simply saying 'no' to alcohol, participants utilized other refusal strategies to avoid social confrontation.

Among patients with substance use disorders (SUD), adult attention deficit hyperactivity disorder (ADHD) is one of the most frequently co-occuring disorder. Those SUD patients with comorbid ADHD show earlier onset of substance use, more severe SUD and poor treatment outcomes. Therefore, early recognition of ADHD is highly rele - vant within this patient population. The results of available screening instruments may lay the foundation of timely ADHD diagnosis. Considering the integrated treatment of patients with a dual ADHD+SUD diagnosis, the applica tion of combined pharmaco- and psychotherapy is recommended. Based on the evidence-and consensus-based suggestions, prescription of long-acting methylphenidate, extended-release amphetamines and atomoxetine with up-titration might be the best choice in the treatment of patients who are either unresponsive to standard dose or characterized by therapy resistance. The main purpose of this manuscript is to establish a standing-ground for the effective screening, diagnosis and treatment of ADHD+SUD patients.

Objective: To examine ADHD symptom persistence and subtype stability among substance use disorder (SUD) treatment seekers. Method: In all, 1,276 adult SUD treatment seekers were assessed for childhood and adult ADHD using Conners' Adult ADHD Diagnostic Interview for Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV ; CAADID). A total of 290 (22.7%) participants met CAADID criteria for childhood ADHD and comprise the current study sample. Results: Childhood ADHD persisted into adulthood in 72.8% ( n = 211) of cases. ADHD persistence was significantly associated with a family history of ADHD, and the presence of conduct disorder and antisocial personality disorder. The combined subtype was the most stable into adulthood (78.6%) and this stability was significantly associated with conduct disorder and past treatment of ADHD. Conclusion: ADHD is highly prevalent and persistent among SUD treatment seekers and is associated with the more severe phenotype that is also less likely to remit. Routine screening and follow-up assessment for ADHD is indicated to enhance treatment management and outcomes.

Background: Online activity-based epidemiological surveillance and forecasting is getting more and more attention. To date, Google search volumes have not been assessed for forecasting of tick-borne diseases. Thus, we performed an analysis of forecasting of the Lyme disease incidence based on the traditional data extended with Google Trends., Methods: Data on the weekly incidence of Lyme disease in Germany from 16 June 2013 to 27 May 2018 were obtained from the database of the Robert Koch Institute. Data of Internet searches were obtained from Google Trends searching "Borreliose" in Germany for the "last 5 years" as a timespan category. Data were split into the training (from 16 June 2013 to 11 June 2017) and validation (from 12 June 2017, to 27 May 2018) data sets. A seasonal autoregressive moving average model, SARIMA (0,1,1) (0,1,1) [52] model was selected to describe the time series of the weekly Lyme incidence. After this, we added the Google Trends data as an external regressor and identified the SARIMA (0,1,1) (0,1,1) [52] model as optimal. We made predictions for the validation interval using these two models and compared predictions with the values of the validation data set., Results: Forecasting for the validation timespan resulted in similar values for the models. Comparing the forecasted values with the reported ones resulted in an residual mean squared error (RMSE) of 0.3763; the mean absolute percentage error (MAPE) was 8.233 for the model without Google searches with an RMSE of 0.3732; and the MAPE was 8.17495 for the Google Trends values-expanded model. The difference between the predictive performances was insignificant (Diebold-Mariano Test, p-value = 0.4152)., Conclusion: Google Trends data are a good correlate of the reported incidence of Lyme disease in Germany, but it failed to significantly improve the forecasting accuracy in models based on traditional data., (© 2018 Blackwell Verlag GmbH.)

Background: In recent years, drug prevention networks and drug education programs have started using Web-based or mobile phone apps as novel prevention tools, testing their efficacy compared with face-to-face prevention., Objective: The aim of this study was to assess the potential of an interactive app called Once Upon a High (VoltEgySzer)., Methods: The app approaches drug prevention from 6 different aspects, and it addresses youngsters with 6 different modules: (1) interactive comics/cartoons, telling stories of recovery; (2) quiz game; (3) roleplay game; (4) introduction of psychoactive drugs; (5) information on the somatic and psychological effects of psychoactive substances; (6) list of available treatment units, rehabs, and self-support groups in Hungary. Students of 2 vocational schools and 2 high schools filled out a questionnaire at a baseline (T0) and a 2-month follow-up (T1) data collection session. Students of 1 vocational school and 1 high school downloaded the Once Upon a High app (app group), whereas students from the other vocational school and high school did not (nonapp group). The time points of T0 and T1 questionnaires contained demographic variables, items with regard to substance use characteristics for both legal and illegal substances, including novel psychoactive substance, exercise habits, knowledge about psychoactive substances, attitudes toward substance users and validated instruments measuring the severity of tobacco (Fagerström Test for Nicotine Dependence), alcohol (Alcohol Use Disorder Identification Test), cannabis (Cannabis Abuse Screening Test), and synthetic cannabinoid consumption. Beliefs about substance use (Beliefs About Substance Abuse) and perceived self-efficacy (General Perceived Self-Efficacy) were also measured. At T1, members of the app group provided additional evaluation of the app., Results: There were 386 students who participated in the T0 session. After dropout, 246 students took part in T1 data collection procedure. Alcohol was the most frequently consumed psychoactive substance (334/364, 91.8% lifetime use), followed by tobacco (252/386, 65.3%, lifetime use) and cannabis (43/323, 13.3% lifetime use). Decreased self-efficacy (beta=-.29, P=.04) and increased daily physical exercise frequencies (beta=.04, P<.001) predicted higher frequencies of past month energy drink consumption, whereas elevated past month alcohol consumption was mainly predicted by a decrease in negative attitudes toward substance users (beta=-.13, P=.04) in the regression models. Once Upon a High was found to be effective only in reducing energy drink consumption (beta=-1.13, P=.04) after controlling for design effect, whereas perceived utility of the app showed correlation with a decreasing alcohol use (r S(44) =.32, P=.03). The roleplay module of the app was found to be the most preferred aspect of the app by the respondents., Conclusions: The Once Upon a High app can be a useful tool to assist preventive intervention programs by increasing knowledge and self-efficacy; however, its efficacy in reducing or preventing substance use needs to be improved and further studied. Additional potential impacts of the app need further testing., (©Máté Kapitány-Fövény, Eszter Vagdalt, Zsófia Ruttkay, Róbert Urbán, Mara J Richman, Zsolt Demetrovics.

Background: Mental disorders may show inherent cross-national variability in their prevalence. A considerable number of meta-analyses attribute this heterogeneity to the methodological diversity in published epidemiological studies. Cultural values are characteristically not assessed in meta-regression models as potential covariates., Aim: Our aim was to conduct a meta-regression analysis to explore to what extent certain cultural values and immigration rates (as indicator of cultural diversity) might be associated with the cross-national heterogeneity of prevalence rates., Method: To minimize methodological differences that may exert a confounding effect, prevalence rates were obtained from the World Health Organization's (WHO) World Mental Health Survey Initiative. Cultural indices (overall emancipative values; overall secular values) were collected from the World Value Survey, while immigration rates were registered by utilizing the data of the United Nations' World Population Policies 2005 report., Results: Meta-regression analysis indicated that overall emancipative values (i.e. promoting self-expression, non-violent protest) showed significant connection with lifetime and last year prevalence of any mood disorders ( Z  = 4.71, p  = .001; Z  = 2.35, p  = .02) and any internalizing disorders (a merged category that combined mood and anxiety disorders; Z  = 2.82, p  = .004; Z  = 2.34, p  = .02). Overall secular values (i.e. rejecting authority and obedience) were negatively associated with last year prevalence of depression ( Z  = -2.75, p  = .06). Multistep regression analysis indicated that immigration rate moderated the connection between cultural values and mental disorders. Countries with higher immigration rates showed higher emancipative and secular values., Conclusion: Our findings might function as potential foundation for formulating hypotheses regarding the cultural context's influence on the population's mental health.

Media stories often suggest that those working in the creative arts appear to use and abuse psychoactive substances. The aim of the present study was to analyze the relationship between the use of psychoactive substances and the presence of psychological disorders among art and non-art students. Questionnaires related to these two areas were completed by 182 art students in higher education and a control group of 704 non-art university students. To assess psychoactive substance use, a structured questionnaire including the Cannabis Abuse Screening Test (CAST) and the Alcohol Use Disorders Identification Test (AUDIT) was administered to participants. Psychological disorders were assessed using the Hungarian version of the Brief Symptom Inventory (BSI) and the Global Severity Index (GSI). After analyzing the data, significant differences were found between the two groups regarding their first use of psychoactive substances. Art students' current substance use was found to be significantly more frequent compared to the control group. In relation to psychological disorders, art students scored significantly higher on three scales of the BSI (i.e., psychoticism, hostility, and phobic anxiety). Overall, a significantly higher proportion of artists were labeled as "problematic" using the GSI. The results suggest that artists have a higher risk of both substance use and experiencing psychological disorders., Competing Interests: All the participants provided informed concent and the study was approved by the research team's university ethics committee.The authors declare that they have no conflict of interest.All procedures performed in this study involving human participants were in accordance with the ethical standards of University’s Research Ethics Board and with the 1975 Helsinki Declaration.Informed consent was obtained from all participants.

Introduction: In recent years, the involvement of GHB in drug facilitated sexual assaults has been one of the most frequently studied aspects of GHB in both clinical and non-clinical settings. GHB-involved acquisitory crimes, however, can be mentioned as understudied research topics, as well as the poisoning severity properties of GHB., Measures: The medical reports of Péterfy Sándor Street Hospital Clinic and Casualty Centre's 408 GHB-intoxication cases (352 patients) were reviewed and registered. Analyzed data consisted of epicrisis, serum and urine concentration of various substances (including GHB), scores of Glasgow Coma Scale and Poisoning Severity Score., Results: Majority of the patients were males, in their twenties. GHB was detected in 34.1% and it was solely consumed in 27.7% of all the cases. Ethanol was found to be the most frequently co-ingested substance. A higher rate of severe poisonings was observed among males. We found significant difference in the frequency of enduring sexual assaults and acquisitory crimes between intentional and unintentional GHB intake cases. Among unintentional GHB intake cases, 6.5% endured GHB-involved sexual assaults, whereas 21.7% endured an acquisitory crime. Among recurrent GHB intoxication cases generated by the same patients, voluntary and sole GHB consumptions were more frequently observed, however, enduring any crime was less characteristic., Discussion: Our results regarding demographic and substance use characteristics and the frequency of GHB-facilitated sexual assaults are in line with former findings. Enduring acquisitory crimes due to unintentional GHB intake was found to be more inherent than enduring sexual assaults. Authors emphasise that the victims of these acquisitory crimes were typically males., Conclusion: GHB's role in drug facilitated acquisitory crimes seems to be significant, although the decrease in GHB's popularity is observed among intoxicated patients as well. The need for further research on GHB's impact on cognitive impairment and on sexual correlates of intentional GHB use is addressed by the authors., (Copyright © 2017 Elsevier B.V.

Objective: With growing access to the Internet, people who use drugs and traffickers started to obtain information about novel psychoactive substances (NPS) via online platforms. This paper aims to analyze whether a decreasing Web interest in formerly banned substances-cocaine, heroin, and MDMA-and the legislative status of mephedrone predict Web interest about this NPS., Methods: Google Trends was used to measure changes of Web interest on cocaine, heroin, MDMA, and mephedrone. Google search results for mephedrone within the same time frame were analyzed and categorized., Results: Web interest about classic drugs found to be more persistent. Regarding geographical distribution, location of Web searches for heroin and cocaine was less centralized. Illicit status of mephedrone was a negative predictor of its Web search query rates. The connection between mephedrone-related Web search rates and legislative status of this substance was significantly mediated by ecstasy-related Web search queries, the number of documentaries, and forum/blog entries about mephedrone., Conclusions: The results might provide support for the hypothesis that mephedrone's popularity was highly correlated with its legal status as well as it functioned as a potential substitute for MDMA. Google Trends was found to be a useful tool for testing theoretical assumptions about NPS., (Copyright © 2017 John Wiley & Sons, Ltd.)

Objective: Over the past 5 years, a shift to the use of novel psychoactive substances (NPS) has been observed among opioid users. The aim of this study was to assess the potential reasons for NPS use among treatment-seeking patients receiving opiate substitution therapy., Method: A structured questionnaire was filled out by a sample of 198 opiate dependent patients of Hungary's National Institute of Psychiatry and Addiction. This questionnaire assessed demographics, treatment characteristics, lifetime substance use, potential reasons for NPS use, negative life events (Life Events Scale), and psychiatric symptoms (Brief Symptom Inventory)., Results: The most frequent reasons for NPS use were curiosity, replacing other drugs, and easy availability. The majority of the respondents used synthetic cathinones and chose practical reasons, not psychopharmacological preferences. A series of binary logistic regressions indicated that lifetime amphetamine use (OR = 4.64, 95% CI [2.16, 9.96]) and more severe psychiatric symptoms (OR = 1.89, 95% CI [1.18, 3.04]) may predict NPS use. Time spent in treatment was a minor protective factor (OR = 0.92, 95% CI [0.86, 0.99])., Conclusion: Synthetic cathinones might still substitute amphetamine-derivatives, although these NPS are no longer legal. There is a need for the regular screening of psychiatric symptoms and the use of family therapy among participants on opioid substitution programs., (Copyright © 2017 John Wiley & Sons, Ltd.)

Objective: In recent years, increasing intravenous mephedrone use was reported in several countries. The aim of this study was to describe the characteristics of such a form of mephedrone use, while identifying the differences between injectors and non-injectors in patterns of mephedrone use and psychiatric symptom status., Methods: One hundred and forty-five mephedrone users were surveyed on patterns of mephedrone use using a structured questionnaire as well as the Brief Symptom Inventory., Results: Majority of users received mephedrone from acquaintances and used it in discos/parties settings regarding both first and current mephedrone use. Intranasal use was the most typical route of administration (84.4%). Injectors (11%) used the drug more frequently and in higher dosages. This group included a greater proportion of opiate users (37.5%) and showed more diffuse psychiatric symptoms. Regarding the predictors of being an injector, heroin use showed the highest odds ratio., Conclusions: Intravenous mephedrone use is associated with a higher risk of harmful drug use, elevated psychiatric symptom profile and increased possibility of mephedrone being considered as an addictive substance. These findings might be important in efficient treatment planning., (Copyright © 2015 John Wiley & Sons, Ltd.)

Objective: Various studies have dealt with gamma-hydroxybutyrate's (GHB) potential role in sexual assaults, while the sexual correlates of intentional recreational GHB use have not well been highlighted. Our study aims to explore GHB's sexual effects, the patterns of choice of sexual partners, the frequency of experienced blackouts, and endured sexual or acquisitory crimes as a result of GHB use., Methods: Sixty recreational GHB users filled out a questionnaire on experienced subjective, somatic, and sexual effects of GHB, the frequency of blackouts due to their GHB use, and items on their sexual experiences in relation to GHB use., Results: Of the sample, 25.9% reported increased sexual arousal as well as more intense attraction towards their sexual partners and increased sexual openness when using GHB; 34.8% had sexual intercourse with strangers, or with others, but not with their partners when using GHB; and 8.6% were victims of acquisitory crimes, whereas 3.4% were victims of a sexual assault. Furthermore, 24.6% typically experienced blackouts when using GHB., Conclusion: Gamma-hydroxybutyrate seems to be a potential substitute for both stimulant and depressant substances. Increased sexual desire and disinhibition may lead to a more frequent and potentially more riskful sexual activity. Experienced blackouts need to be considered as risk factors for suffering sexual or acquisitory crimes., (Copyright © 2015 John Wiley & Sons, Ltd.)

The use of substances to enhance human abilities is a constant and cross-cultural feature in the evolution of humanity. Although much has changed over time, the availability on the Internet, often supported by misleading marketing strategies, has made their use even more likely and risky. This paper will explore the case of Mitragyna speciosa Korth. (kratom), a tropical tree used traditionally to combat fatigue and improve work productivity among farm populations in Southeast Asia, which has recently become popular as novel psychoactive substance in Western countries. Specifically, it (i) reviews the state of the art on kratom pharmacology and identification; (ii) provides a comprehensive overview of kratom use cross-culturally; (iii) explores the subjective experiences of users; (iv) identifies potential risks and side-effects related to its consumption. Finally, it concludes that the use of kratom is not negligible, especially for self-medication, and more clinical, pharmacological, and socioanthropological studies as well as a better international collaboration are needed to tackle this marginally explored phenomenon.

Aims: To determine comorbidity patterns in treatment-seeking substance use disorder (SUD) patients with and without adult attention deficit hyperactivity disorder (ADHD), with an emphasis on subgroups defined by ADHD subtype, taking into account differences related to gender and primary substance of abuse., Design: Data were obtained from the cross-sectional International ADHD in Substance use disorder Prevalence (IASP) study., Setting: Forty-seven centres of SUD treatment in 10 countries., Participants: A total of 1205 treatment-seeking SUD patients., Measurements: Structured diagnostic assessments were used for all disorders: presence of ADHD was assessed with the Conners' Adult ADHD Diagnostic Interview for DSM-IV (CAADID), the presence of antisocial personality disorder (ASPD), major depression (MD) and (hypo)manic episode (HME) was assessed with the Mini International Neuropsychiatric Interview-Plus (MINI Plus), and the presence of borderline personality disorder (BPD) was assessed with the Structured Clinical Interview for DSM-IV Axis II (SCID II)., Findings: The prevalence of DSM-IV adult ADHD in this SUD sample was 13.9%. ASPD [odds ratio (OR) = 2.8, 95% confidence interval (CI) = 1.8-4.2], BPD (OR = 7.0, 95% CI = 3.1-15.6 for alcohol; OR = 3.4, 95% CI = 1.8-6.4 for drugs), MD in patients with alcohol as primary substance of abuse (OR = 4.1, 95% CI = 2.1-7.8) and HME (OR = 4.3, 95% CI = 2.1-8.7) were all more prevalent in ADHD(+) compared with ADHD(-) patients (P < 0.001). These results also indicate increased levels of BPD and MD for alcohol compared with drugs as primary substance of abuse. Comorbidity patterns differed between ADHD subtypes with increased MD in the inattentive and combined subtype (P < 0.01), increased HME and ASPD in the hyperactive/impulsive (P < 0.01) and combined subtypes (P < 0.001) and increased BPD in all subtypes (P < 0.001) compared with SUD patients without ADHD. Seventy-five per cent of ADHD patients had at least one additional comorbid disorder compared with 37% of SUD patients without ADHD., Conclusions: Treatment-seeking substance use disorder patients with attention deficit hyperactivity disorder are at a very high risk for additional externalizing disorders., (© 2013 Society for the Study of Addiction.)

Background: Available studies vary in their estimated prevalence of attention deficit/hyperactivity disorder (ADHD) in substance use disorder (SUD) patients, ranging from 2 to 83%. A better understanding of the possible reasons for this variability and the effect of the change from DSM-IV to DSM-5 is needed., Methods: A two stage international multi-center, cross-sectional study in 10 countries, among patients form inpatient and outpatient addiction treatment centers for alcohol and/or drug use disorder patients. A total of 3558 treatment seeking SUD patients were screened for adult ADHD. A subsample of 1276 subjects, both screen positive and screen negative patients, participated in a structured diagnostic interview., Results: Prevalence of DSM-IV and DSM-5 adult ADHD varied for DSM-IV from 5.4% (CI 95%: 2.4-8.3) for Hungary to 31.3% (CI 95%:25.2-37.5) for Norway and for DSM-5 from 7.6% (CI 95%: 4.1-11.1) for Hungary to 32.6% (CI 95%: 26.4-38.8) for Norway. Using the same assessment procedures in all countries and centers resulted in substantial reduction of the variability in the prevalence of adult ADHD reported in previous studies among SUD patients (2-83%→5.4-31.3%). The remaining variability was partly explained by primary substance of abuse and by country (Nordic versus non-Nordic countries). Prevalence estimates for DSM-5 were slightly higher than for DSM-IV., Conclusions: Given the generally high prevalence of adult ADHD, all treatment seeking SUD patients should be screened and, after a confirmed diagnosis, treated for ADHD since the literature indicates poor prognoses of SUD in treatment seeking SUD patients with ADHD., (Copyright © 2013 The Authors.

Background: To detect attention deficit hyperactivity disorder (ADHD) in treatment seeking substance use disorders (SUD) patients, a valid screening instrument is needed., Objectives: To test the performance of the Adult ADHD Self-Report Scale V 1.1(ASRS) for adult ADHD in an international sample of treatment seeking SUD patients for DSM-IV-TR; for the proposed DSM-5 criteria; in different subpopulations, at intake and 1-2 weeks after intake; using different scoring algorithms; and different externalizing disorders as external criterion (including adult ADHD, bipolar disorder, antisocial and borderline personality disorder)., Methods: In 1138 treatment seeking SUD subjects, ASRS performance was determined using diagnoses based on Conner's Adult ADHD Diagnostic Interview for DSM-IV (CAADID) as gold standard., Results: The prevalence of adult ADHD was 13.0% (95% CI: 11.0-15.0%). The overall positive predictive value (PPV) of the ASRS was 0.26 (95% CI: 0.22-0.30), the negative predictive value (NPV) was 0.97 (95% CI: 0.96-0.98). The sensitivity (0.84, 95% CI: 0.76-0.88) and specificity (0.66, 95% CI: 0.63-0.69) measured at admission were similar to the sensitivity (0.88, 95% CI: 0.83-0.93) and specificity (0.67, 95% CI: 0.64-0.70) measured 2 weeks after admission. Sensitivity was similar, but specificity was significantly better in patients with alcohol compared to (illicit) drugs as the primary substance of abuse (0.76 vs. 0.56). ASRS was not a good screener for externalizing disorders other than ADHD., Conclusions: The ASRS is a sensitive screener for identifying possible ADHD cases with very few missed cases among those screening negative in this population., (Copyright © 2013 Elsevier Ireland Ltd.

Attention deficit/hyperactivity disorder (ADHD) is an increasingly recognized comorbid condition in subjects with substance use disorders (SUDs). This paper describes the methods and study population of the International ADHD in Substance Use Disorders Prevalence (IASP) study. Objectives of the IASP are to determine the prevalence of ADHD in adult treatment seeking patients with SUD in different countries and SUD populations, determine the reliability and validity of the Adult ADHD Self-report Scale V 1.1 (ASRS) as ADHD screening instrument in SUD populations, investigate the comorbidity profile of SUD patients with and without ADHD, compare risk factors and protective factors in SUD patients with and without a comorbid diagnosis of ADHD, and increase our knowledge about the relationship between ADHD and the onset and course of SUD. In this cross-sectional, multi-centre two stage study, subjects were screened for ADHD with the ASRS, diagnosed with the Conner's Adult ADHD Diagnostic Interview for DSM-IV (CAADID), and evaluated for SUD, major depression, bipolar disorder, anti social personality disorder and borderline personality disorder. Three thousand five hundred and fifty-eight subjects from 10 countries were included. Of these 40.9% screened positive for ADHD. This is the largest international study on this population evaluating ADHD and comorbid disorders., (Copyright © 2013 John Wiley & Sons, Ltd.)

Objective: In the past 25-30 years, a large number of synthetic and non-synthetic drugs have appeared on the recreational scene, but with the exception of 4-methylmethcathinone (mephedrone), none of these substances reached the popularity of ecstasy [3,4-methylenedioxy-N-methylamphetamine, (MDMA)]. Authors aimed to determine the subjective effects of mephedrone in order to understand how mephedrone can serve as a potential substitute for entactogens, such as MDMA., Methods: One hundred forty-five mephedrone users--recruited by snowball method--filled out a questionnaire on their patterns of use and experienced subjective effects of mephedrone., Results: Factor analysis revealed six factors of mephedrone-induced subjective effects: positive emotions, sensibility, adverse somatic effects, adverse psychological effects, stimulant effects, and psychedelic effects. A preference list of subjective effects indicates that mephedrone is popular primarily for its psychostimulant and entactogen effects. Latent class analysis identified two classes of mephedrone users, with closely parallel profiles. The two classes differed in severity of subjective experience in a way that was consistent across the six dimensions., Conclusions: By having similar subjective effects as MDMA and other entactogens, mephedrone seems able to substitute other enactogenic stimulants., (Copyright © 2013 John Wiley & Sons, Ltd.)
