Behavioral economics indices predict alcohol use and consequences in young men at 4‐year follow‐up

Jacques Gaume, James G. Murphy, Joseph Studer, Jean‐Bernard Daeppen, more

Background and Aims The alcohol purchase task (APT), which presents a scenario and asks participants how many drinks they would purchase and consume at different prices, generates indices of alcohol reward value that have shown robust associations with alcohol‐related outcomes in numerous studies. The aim was to test its prospective validity at 4‐year follow‐up. Design Prospective cohort study...

Background and aims Short screenings for alcohol use disorder (AUD) are crucial for public health purposes, but current self‐reported measures have several pitfalls and may be unreliable. The main aim of our study was to provide empirical evidence on the psychometric performance of self‐reports currently used. Our research questions were: compared with a gold standard clinical interview, how accurate...

Alcohol‐induced blackouts at age 20 predict the incidence, maintenance and severity of alcohol dependence at age 25: a prospective study in a sample of young Swiss men

Joseph Studer, Gerhard Gmel, Nicolas Bertholet, Simon Marmet, more

Addiction > 114 > 9 > 1556 - 1566

Background and Aims Alcohol‐induced blackout (AIB) is a common alcohol‐related adverse event occurring during teenage years. Although research provides evidence that AIB predicts acute negative consequences, less is known about the associations of AIB with chronic consequences, such as alcohol dependence (AD). This study estimated the associations between an experience of AIB at age 20 and the incidence,...

Gerhard Gmel, Yasser Khazaal, Joseph Studer, Stéphanie Baggio, more

International Journal of Methods in Psychiatric Research > 28 > 1 > n/a - n/a

Stéphanie Baggio, Joseph Studer, Ana Fructuoso, Véronique S. Grazioli, more

International Journal of Public Health > 2019 > 64 > 2 > 165-172

Objectives Transition into adulthood is a risky period for young people with attention deficit-hyperactivity disorder (ADHD), but empirical studies on this topic are scarce. This study investigated the association between the level of ADHD symptoms and transition into adulthood. Methods Data were collected in the Cohort Study of Substance Use and Risk Factors among a representative sample of young...

Nicolas Bertholet, Joseph Studer, John A. Cunningham, Gerhard Gmel, more

Addiction > 113 > 8 > 1517 - 1521

Aim To estimate the long‐term efficacy of an internet‐based brief intervention (IBI) in decreasing alcohol use among men on (1) number of drinks/week and (2) monthly or more binge drinking prevalence. In addition, overall changes in alcohol use were assessed. Design Participants in a cohort study were recruited in a two parallel‐group randomized controlled trial of an IBI versus no‐intervention...

Is gambling involvement a confounding variable for the relationship between Internet gambling and gambling problem severity?

Stéphanie Baggio, Marc Dupuis, André Berchtold, Stanislas Spilka, more

Computers in Human Behavior > 2017 > 71 > C > 148-152

Internet gamblers have more problems gambling than land-based gamblers, but recent studies showed that Internet gamblers are involved in a higher number of gambling activities, which may confound the relationship between Internet gambling and gambling problems. The present study aimed to test whether the relationship between Internet gambling and gambling problems persisted when including variables...

Risky substance use and peer pressure in Swiss young men: Test of moderation effects

Joseph Studer, Stéphanie Baggio, Véronique S. Grazioli, Meichun Mohler-Kuo, more

Drug and Alcohol Dependence > 2016 > 168 > C > 89-98

Peer pressure (PP) toward misconduct is a well-known risk factor for substance use. However, the way it interacts with social factors and the associations of the aspects of PP other than PP toward misconduct have been understudied. This study examined the associations of three aspects of PP with risky substance use and tested whether the associations of PP toward misconduct were moderated by social...

Is attention deficit/hyperactivity disorder among men associated with initiation or escalation of substance use at 15‐month follow‐up? A longitudinal study involving young Swiss men

Tanja Vogel, Geert Dom, Geurt Glind, Joseph Studer, more

Addiction > 111 > 10 > 1867 - 1878

Background and Aims Young adults with attention deficit/hyperactivity disorder (ADHD) show higher substance use disorder (SUD) prevalence relative to non‐ADHD controls; few longitudinal studies have examined the course of substance use with reference to conduct disorder (CD). We compared initiation and escalation of substance use at 15‐month follow‐up in men screened positive or negative for ADHD...

Factor structure and psychometric properties of a French and German shortened version of the Behavioural Inhibition System/Behavioural Activation System scales

Joseph Studer, Stéphanie Baggio, Meichun Mohler‐Kuo, Jean‐Bernard Daeppen, more

International Journal of Methods in Psychiatric Research > 25 > 1 > 44 - 54

The Behavioural Inhibition System/Behavioural Activation System scales (BIS/BAS scales) constitute one of the most prominent questionnaires to assess individual differences in sensitivity to punishment and reward. However, some studies questioned its validity, especially that of the French and German translations. The aim of the present study was to re‐evaluate the psychometric characteristics of...

Reframing video gaming and internet use addiction: empirical cross‐national comparison of heavy use over time and addiction scales among young users

Stéphanie Baggio, Marc Dupuis, Joseph Studer, Stanislas Spilka, more

Addiction > 111 > 3 > 513 - 522

Background and aims Evidence‐based and reliable measures of addictive disorders are needed in general population‐based assessments. One study suggested that heavy use over time (UOT) should be used instead of self‐reported addiction scales (AS). This study compared UOT and AS regarding video gaming and internet use empirically, using associations with comorbid factors. Design Cross‐sectional data...

Eleni Charitonidi, Joseph Studer, Jacques Gaume, Gerhard Gmel, more

BMC Public Health > 2016 > 16 > 1 > 1-11

Background Socioeconomic status (SES) is often inversely related to health outcomes and is likely to play a role in the use of psychoactive substances among young individuals, although little consensus exists on the association between SES and substance use. The purpose of the study was to determine the association of three SES indicators (perceived family income, education level of participants,...

Drinking locations and alcohol-related harm: Cross-sectional and longitudinal associations in a sample of young Swiss men

Joseph Studer, Stéphanie Baggio, Stéphane Deline, Alexandra A. N’Goran, more

International Journal of Drug Policy > 2015 > 26 > 7 > 653-661

Alcohol consumption—in particular drinking volume (DV) and risky single occasion drinking (RSOD)—has been related to a wide range of negative consequences and health problems. Previous studies also suggested that drinking in certain locations may be more strongly associated with the occurrence of alcohol-related harm than drinking in others. However, they were conducted in countries culturally and...
