A comparison of the cheater detection and the unrelated question models: a randomized response survey on physical and cognitive doping in recreationa…
2016
PURPOSE:This study assessed the prevalence of physical and cognitive doping in recreational triathletes with two different randomized response models, that is, the Cheater Detection Model (CDM) and the Unrelated Question Model (UQM). Since both models have been employed in assessing doping, the major objective of this study was to investigate whether the estimates of these two models converge. MATERIAL AND METHODS:An anonymous questionnaire was distributed to 2,967 athletes at two triathlon events (Frankfurt and Wiesbaden, Germany). Doping behavior was assessed either with the CDM (Frankfurt sample, one Wiesbaden subsample) or the UQM (one Wiesbaden subsample). A generalized likelihood-rati…
Kinetics and Topology of DNA Associated with Circulating Extracellular Vesicles Released during Exercise.
2021
AbstractAlthough it is widely accepted that cancer derived extracellular vesicles (EVs) carry DNA cargo, the association of cell-free circulating DNA (cfDNA) and EVs in plasma of healthy humans remains elusive. Using a physiological exercise model, where EVs and cfDNA are synchronously released, we aimed to characterize the kinetics and localization of DNA associated with EVs. EVs were separated from human plasma using size exclusion chromatography or immuno-affinity capture for CD9+, CD63+, and CD81+ EVs. DNA was quantified with an ultra-sensitive qPCR assay targeting repetitive LINE elements, with or without DNase digestion. This model shows that a minute part of circulating cell-free DNA…
Efficacy of Short-term Treatment of Internet and Computer Game Addiction
2019
Importance Internet and computer game addiction represent a growing mental health concern, acknowledged by the World Health Organization. Objective To determine whether manualized cognitive behavioral therapy (CBT), using short-term treatment for internet and computer game addiction (STICA), is efficient in individuals experiencing internet and computer game addiction. Design, Setting, and Participants A multicenter randomized clinical trial was conducted in 4 outpatient clinics in Germany and Austria from January 24, 2012, to June 14, 2017, including follow-ups. Blinded measurements were conducted. A consecutive sample of 143 men was randomized to the treatment group (STICA; n = 72) or wai…
Video game addiction in gambling disorder: clinical, psychopathological, and personality correlates
2014
Objective. We studied the prevalences of video game use (VGU) and addiction (VGA) in gambling disorder (GD) patients and compared them with subjects with non-video game use (non-VGU) in relation to their gambling behavior, psychopathology, and personality characteristics.Method. A sample of 193 GD patients (121 non-VGU, 43 VGU, and 29 VGA) consecutively admitted to our pathological gambling unit participated in the study.Assessment. Measures included the video game dependency test (VDT), symptom checklist-90-revised, and the temperament and character inventory-revised, as well as a number of other GD indices.Results. In GD, the observed prevalence of VG (use or addiction) was 37.3% (95% CI:…
Investigating Risk Factors for Internet Gaming Disorder: A Comparison of Patients with Addictive Gaming, Pathological Gamblers and Healthy Controls r…
2013
Engaging in online games has become increasingly important as a part of leisure activity in adolescents and adults. While the majority of people use these games in a healthy way, epidemiological studies show that some develop excessive use and symptoms that are related to those of substance-related addictions. Despite increasing research concerning the epidemiology of internet gaming disorder (IGD), predisposing factors have been examined to a lesser extent. Knowing about specific risk factors would help clarify the nosological features of IGD and enhance prevention and intervention. This study aimed to evaluate the relationships between personality traits and IGD. A total of 115 patients m…
A contribution to the clinical characterization of Internet addiction in a sample of treatment seekers: validity of assessment, severity of psychopat…
2014
Abstract Objective Internet addiction becomes a growing health problem worldwide with prevalence rates up to 3%. Still, uncertainties exist regarding its diagnostics and clinical characterization. Especially the lacking clinical evidence regarding self-report measures assessing Internet addiction has been criticized. Methods This study aimed to characterize 290 German treatment seekers and to determine the diagnostic accuracy of a self-report scale for Internet addiction. Patients filled in self-report measures (SCL-90R, PHQ, AICA-S – Scale for the Assessment of Internet and Computer game Addiction) and underwent diagnostic interviews to assess symptoms of Internet addiction and level of fu…
The rates of co-occurring behavioural addictions in treatment-seeking individuals with obsessive-compulsive disorder: a preliminary report
2020
Objectives: To assess the rates of co-occurring putative ‘behavioural addictions’ in patients with obsessive-compulsive disorder (OCD). Methods: Twenty-three international centres specialising in the treatment of OCD were invited to participate in a survey of the rates of behavioural addictions and other relevant comorbidity within their samples. Results: Sixteen of 23 (69.6%) invited centres from 13 countries had sufficient data to participate in the survey. The use of validated diagnostic tools was discrepant, with most centres relying on a ‘clinical diagnosis’ to diagnose behavioural addictions. The final sample comprised of 6916 patients with a primary diagnosis of OCD. The reported rat…
Arousal/Stress Effects of “Overwatch” eSports Game Competition in Collegiate Gamers
2022
Kraemer, WJ, Caldwell, LK, Post, EM, Beeler, MK, Emerson, A, Volek, JS, Maresh, CM, Fogt, JS, Fogt, N, Häkkinen, K, Newton, RU, Lopez, P, Sanchez, BN, and Onate, JA. Arousal/stress effects of “Overwatch” eSports game competition in collegiate gamers. J Strength Cond Res XX(X): 000–000, 2022—To date, no physical response data are available for one of the most popular eSport games, Overwatch. The purpose of this investigation was to describe the stress signaling associated with competitive Overwatch play and to understand how acute hormonal responses may affect performance. Thirty-two male college-aged gamers (age: 21.3 ± 2.7 years; estimated time played per week: 18 ± 15 hours) completed the…
Perceptions Underlying Addictive Technology Use Patterns: Insights for Cognitive-Behavioural Therapy
2022
International audience; Cognitive-Behavioural Therapy (CBT) is considered the ‘gold standard’ in the treatment of addictive disorders related to excessive technology use. However, the cognitive components of problematic internet use are not yet well-known. The aim of the present study was to explore the cognitive components, that according to problematic users, can lead to potential internet addiction. A total of 854 European adults completed an online survey using a mixed-methods design. Internet problems and attachment styles were assessed, prevalence rates estimated, correlations, chi-squared automatic interaction detection, and content analysis were performed. Self-reported addictions t…
The implicit motor learning use as a therapeutic tool in frail elderly people
2016
To write, take, walk, talk is a part of our daily. Our motor ability is used to change depending on our environment and our skill, acquired thanks to our experience, learnings, and according to our age. We strive to find optimal solutions, to be more performants, more efficient. But we must be able to discern to act well and act to better discern. This « perception-action » coupling is the basis of the organization of motor control. Human can discern through several sensory systems (Visual, auditory, proprioceptive) intrinsic informations, coming from his own body, and extrinsic informations, from his environment. All of these informations are in the service of the movement and actions of d…
