Although recent research suggests that acute stress influences subsequent decision-making under ambiguity, less is known about the role of personality variables in this relationship. This study tested whether impulsivity traits and acute stress differentially influence the way in which a prior feedback is incorporated into further decisions involving ambiguity. Sixty college students (50% male; aged 18–25 years) were randomly assigned to a stress versus a non-stress condition before completing a laboratory gambling task. The results revealed that independently of the stress condition, subjects behaved as if the odds of winning increase after a single loss. Additionally, stress effects varied as a function of impulsivity traits. Individuals who lacked perseverance (i.e., had difficulty focusing on a difficult or boring task) gambled more after experiencing a loss in the stress condition than did those in the control condition. The present study supports that impulsivity traits can explain the differential effect of stress on the relationship between prior feedback and choices made under ambiguity [less ▲]

Objective: Performance monitoring, which allows efficient behavioral regulation using either internal (error processing) or external (feedback processing) cues, has not yet been explored in binge drinking despite its adaptive importance in everyday life, particularly in the regulation of alcohol consumption. Capitalizing on a theoretical model of risky behaviors, the present study aimed at determining the behavioral and electrophysiological correlates of the cognitive (inhibition) and motivational (reward sensitivity) systems during performance monitoring. Methods: Event-related potentials were recorded from 20 binge drinkers and 20 nonbinge drinkers during two experimental tasks, a speeded Go/No-Go Task [investigating internal error processing by Error-Related Negativity (ERN) and error positivity (Pe)] and a Balloon Analogue Risk Task [investigating external feedback processing by Feedback-Related Negativity (FRN) and P3]. Results: While no group differences were observed at the behavioral level, electrophysiological results showed that binge drinkers, despite having intact feedback-related components, presented modified error-monitoring components (i.e. larger ERN amplitude, delayed Pe latency). Conclusions: Internal performance monitoring is impaired in binge drinkers, showing an abnormal automatic processing of response errors (ERN) and a decreased processing of their motivational significance (Pe). Significance: These results suggest that the electrophysiological correlates of inhibitory control allow identifying the specific binge drinking consumption pattern. [less ▲]

Some people have serious problems controlling their Internet and video game use. The DSM-5 now includes a proposal for 'Internet Gaming Disorder' (IGD) as a condition in need of further study. Various studies aim to validate the proposed diagnostic criteria for IGD and multiple new scales have been introduced that cover the suggested criteria. Using a structured approach, we demonstrate that IGD might be better interpreted as a formative construct, as opposed to the current practice of conceptualizing it as a reflective construct. Incorrectly approaching a formative construct as a reflective one causes serious problems in scale development, including: (i) incorrect reliance on item-to-total scale correlation to exclude items and incorrectly relying on indices of inter-item reliability that do not fit the measurement model (e.g., Cronbach's alpha); (ii) incorrect interpretation of composite or mean scores that assume all items are equal in contributing value to a sum score; and (iii) biased estimation of model parameters in statistical models. We show that these issues are impacting current validation efforts through two recent examples. A reinterpretation of IGD as a formative construct has broad consequences for current validation efforts and provides opportunities to reanalyze existing data. We discuss three broad implications for current research: (i) composite latent constructs should be defined and used in models; (ii) item exclusion and selection should not rely on item-to-total scale correlations; and (iii) existing definitions of IGD should be enriched further.

Background: Impairments in executive functions (EFs) are related to binge drinking in young adulthood, but research on how EFs influence future binge drinking is lacking. The aim of the current report is therefore to investigate the association between various EFs and later severity of, and change in, binge drinking over a prolonged period during young adulthood. Methods: At baseline, 121 students reported on their alcohol habits (the Alcohol use disorder identification test; Alcohol use questionnaire). Concurrently, EFs (working memory, reversal, set-shifting, response inhibition, response monitoring and decision-making (with ambiguity and implicit risk)) were assessed. Eighteen months later, information on alcohol habits for 103 of the participants were gathered. Data were analyzed by means of multilevel regression modeling. Results: Future severity of binge drinking was uniquely predicted by performance on the Information sampling task, assessing risky decision-making (β = -1.86, 95% CI: -3.69, -0.04). None of the study variables predicted severity or change in binge drinking. Conclusion: Future severity of binge was associated with making risky decisions in the prospect for gain, suggesting reward hypersensitivity. Future studies should aim at clarifying whether there is a causal association between decision-making style and binge drinking. Performance on all executive tasks was unrelated to change in binge drinking patterns; however, the finding was limited by overall small changes, and needs to be confirmed with longer follow-up periods.

Cognitive models posit that social anxiety disorder (SAD) is maintained by biased informationprocessing vis-à-vis threat of social exclusion. However, uncertainty still abounds regarding the very nature of this sensitivity to social exclusion in SAD. Especially, brain alterations related to social exclusion have not been explored in SAD. Our primary purpose was thus to determine both the selfreport and neural correlates of social exclusion in this population. 23 patients with SAD and 23 matched nonanxious controls played a virtual game (“Cyberball”) during fMRI recording. Participants were frst included by other players, then excluded, and fnally re-included. At the behavioral level, patients with SAD exhibited signifcantly higher levels of social exclusion feelings than nonanxious controls. At the brain level, patients with SAD exhibited signifcantly higher activation within the left inferior frontal gyrus relative to nonanxious controls during the re-inclusion phase. Moreover, self-report of social exclusion correlates with the activity of this cluster among individuals qualifying for SAD diagnosis. Our pattern of fndings lends strong support to the notion that SAD may be better portrayed by a poor ability to recover following social exclusion than during social exclusion per se. These fndings value social neuroscience as an innovative procedure to gain new insight into the underlying mechanisms of SAD. [less ▲]

Previous research has identified specific gambling motives and linked them with both healthy and disordered gambling. The Gambling Motives Questionnaire (GMQ) is currently the most widely used measure for these motives. The present study aimed to offer a French validation of the latest version of this scale, the GMQ-Financial (GMQ-F), which measures four distinct motives (enhancement, social, coping, financial). The French GMQ-F was completed by 278 gamblers from the community and 22 treatment-seeking pathological gamblers, along with scales assessing gambling cognitions, impulsivity, disordered gambling symptoms and psychopathological symptoms. Confirmatory factor analysis supported the expected four-factor model. The GMQ-F subscales have good internal reliability. Validity of the GMQ-F is supported by specific correlations with the other constructs measured. Pathological gamblers differed from gamblers from the community on all but one (social) of the GMQ-F subscales. The French GMQ-F presents good psychometric properties and constitutes a reliable instrument for measuring gambling motives in research and clinical practice. © 2016 Informa UK Limited, trading as Taylor & Francis Group [less ▲]

Impulsivity (and related traits reward/punishment sensitivity and tolerance to delayed rewards) and gambling cognitions have been linked to gambling. However, their independent associations with gambling preferences and clinical status have never been dissociated. The current study applied a data-driven strategy to identify gambling preferences, based on gambling frequency in several modalities. The two resulting factors were used to classify gambling disorder patients (GDPs) and non-problem recreational gamblers (RGs) into Type I (preferring cards, casino games and skill-based bets) and Type II (preferring slot machines, lotteries/pools and bingo). Participants were assessed in impulsivity, delay discounting, reward/punishment sensitivity, gambling-related cognitions, gambling severity, gambling frequency and average amount gambled per episode. GDPs scored higher than RGs in positive and negative urgency, delay discounting, reward sensitivity and intensity of gambling-related cognitions, but less in lack of perseverance. Additionally, Type II gamblers had greater difficulties delaying gratification, whereas Type I gamblers showed higher cognitive distortion and reward sensitivity levels. In practical terms, the finding that some characteristics are equally pervasive in disordered gamblers independently of their preferences (affect-driven impulsivity), whereas others (distorted cognitions, reward sensitivity, delay discounting) are more prominent in one type or the other, provides a basis to establish targets’ priority in therapy. © 2017 Informa UK Limited, trading as Taylor & Francis Group [less ▲]

RATIONALE: The cognitive deficits observed in young binge drinkers have been largely documented during the last decade. Yet, these earlier studies have mainly focused on high-level cognitive abilities (particularly memory and executive functions), and uncertainty thus still abounds regarding the integrity of less complex cognitive processes in binge drinking. This is particularly true for attentional abilities, which play a crucial role in behavior regulation and are impaired in other alcohol-related disorders. OBJECTIVES AND METHODS: To specify the attentional deficits associated with binge drinking, two groups of university students (40 binge drinkers and 40 matched controls) performed the Attention Network Task, a theoretically grounded test assessing three independent attentional networks: alerting, orienting, and executive control. RESULTS: Binge drinkers displayed preserved orienting performance but impaired alerting and executive control. Binge drinking is thus not related to a general attentional impairment but rather to specific impairments of the alerting and executive control networks. CONCLUSIONS: These results underline that, beyond the already explored high-level deficits, binge drinking is also related to impairments for attentional abilities. In view of the role played by attentional impairments in alcohol dependence, the present data also suggest that rehabilitation programs should be developed to improve attentional abilities at the early stages of alcohol-related disorders.

Background and aims: The DSM-5 includes criteria for diagnosing Internet gaming disorder (IGD) that are adapted from substance abuse and widely used in research and clinical contexts, although evidence supporting their validity remains scarce. The present study compared online gamers who do or do not endorse IGD criteria regarding self-control-related abilities (impulsivity, inhibitory control, and decision making), considered the hallmarks of addictive behaviors. Method: A double approach was adopted to distinguish pathological from recreational gamers in a sample of gamers: The first is the classic DSM-5 approach (≥5 criteria required to endorse the IGD diagnosis), and the second consists in using latent class analysis (LCA) for IGD criteria to distinguish gamers’ subgroups. We computed comparisons separately for each approach. Ninety-seven volunteer gamers from the community were recruited. Self-reported questionnaires were used to measure demographic and game-related characteristics, problematic online gaming (with the Problematic Online Gaming Questionnaire), impulsivity (with the UPPS-P Impulsive Behavior Scale), and depression (with the Beck Depression Inventory-II). Experimental tasks were used to measure inhibitory control (Hybrid-Stop Task) and decision-making abilities (Game of Dice Task). Results: Thirty-two participants met IGD criteria (33% of the sample), whereas LCA identified two groups of gamers (pathological [35%] and recreational). Comparisons that used both approaches (DSM-5 and LCA) failed to identify significant differences regarding all constructs except for variables related to actual or problematic gaming behaviors. Discussion: The validity of IGD criteria is questioned, mostly with respect to their relevance in distinguishing high engagement from pathological involvement in video games. [less ▲]

Objective: To examine the association between adolescent at-risk or problem gambling (ARPG) and medicine used to treat nervousness in a large-scale nationally representative sample of Italian adolescents. Study design: Data from the 2013 to 2014 Health Behaviour in School-aged Children Survey was used for cross-sectional analyses (a sample of 20,791 15-year-old students). Self-administered questionnaires were completed by a representative sample of high-school students. Respondents’ ARPG, use of medicine for nervousness and potential confounding factors were assessed. Multilevel logistic regression analyses were used to test the association between medicine use to treat nervousness and ARPG. Results: The overall prevalence of adolescents reporting medicine use for nervousness in the last month was 6.3%. The odds of ARPG were 3 times higher among adolescents who used medicine for nervousness compared to that among adolescents who did not take such medicine (OR 2.96, 95% CI 2.07–4.25). Importantly, the association between medicine used to treat nervousness and ARPG did not vary significantly when viewed in light of psychological symptoms. Conclusions: Medicine use to treat nervousness is associated with increased risk of gambling-related harm. [less ▲]

Cognitive models posit that social anxiety disorder (SAD) is associated with and maintained by attentional bias (AB) for social threat. However, over the last years, it has been suggested that AB in SAD may result from a decreased activation of the left prefrontal cortex, and particularly of its dorsolateral part (dlPFC). Accordingly, a transient increase of neural activity within the left dlPFC via non-invasive brain stimulation decreases AB in non-anxious control participants. Yet, none of these studies focused on SAD. This is especially unfortunate as SAD constitutes the main target for which a genuine reduction of AB may be most appropriate. In this experiment, we sought to investigate the causal influence of left dlPFC neuromodulation on AB among 19 female individuals with a DSM-5 diagnosis of SAD. We adopted a double-blind within-subject protocol in which we delivered a single-session of anodal versus sham transcranial Direct Current Stimulation (tDCS) over the left dlPFC during the completion of a probe discrimination task assessing AB. Consistent with our hypothesis, participants demonstrated a significant decrease in AB during the anodal tDCS over the left DLPFC relative to the sham stimulation. These findings value tDCS as an innovative procedure to gain new insight into the underlying mechanisms of SAD. [less ▲]

The association between traumatic experiences, alexithymia, and substance abuse is well established. Less is known about the role of traumatic experiences and alexithymia in the onset and maintenance of Internet-related disorders. In the present study, self-report measures on traumatic experiences, alexithymia, and problematic Internet use were administered to 358 high school students (57% females) aged 18-19years old, to test whether alexithymic traits mediated the relationship between traumatic experiences and Internet addiction symptoms, and whether gender moderated the proposed mediation in the sample. While partial mediation occurred in the entire sample, gender directly affected the relationship between the investigated constructs: Internet addiction symptoms were independently related to traumatic experiences among males, and to alexithymic traits among females. Therefore, the results of this study suggest that trauma memories among males, and problems with affect regulation among females, may increase the risk of problematic Internet use during late adolescence. Such findings might have relevant implications to inform any treatment plan for late adolescent students who are overinvolved with online activities, pointing out that tailored approaches to their problems and difficulties are particularly needed in clinical practice.

Objective: Huntington’s disease (HD) is characterized by motor and cognitive impairments including memory, executive, and attentional functions. However, because earlier studies relied on multidetermined attentional tasks, uncertainty still abounds regarding the differential deficit across attentional subcomponents. Likewise, the evolution of these deficits during the successive stages of HD remains unclear. The present study simultaneously explored 3 distinct networks of attention (alerting, orienting, executive conflict) in preclinical and clinical HD. Method: Thirty-eight HD patients (18 preclinical) and 38 matched healthy controls completed the attention network test, an integrated and theoretically grounded task assessing the integrity of 3 attentional networks. Results: Preclinical HD was not characterized by any attentional deficit compared to controls. Conversely, clinical HD was associated with a differential deficit across the 3 attentional networks under investigation, showing preserved performance for alerting and orienting networks but massive and specific impairment for the executive conflict network. This indexes an impaired use of executive control to resolve the conflict between task-relevant stimuli and interfering task-irrelevant ones. Conclusion: Clinical HD does not lead to a global attentional deficit but rather to a specific impairment for the executive control of attention. Moreover, the absence of attentional deficits in preclinical HD suggests that these deficits are absent at the initial stages of the disease. In view of their impact on everyday life, attentional deficits should be considered in clinical contexts. Therapeutic programs improving the executive control of attention by neuropsychology and neuromodulation should be promoted. [less ▲]

[Objective] To investigate the differences of socio-demographics and smartphone use features among Chinese college students between problematic smartphone user (PSU) and non-PSU, and to clarify the link between PSU and psychopathological symptoms (anxiety and depression). [Methods] A total of 1 205 undergraduates from 35 classes of 8 universities or colleges, stratified with different school levels, were selected using the cluster random sampling strategy. The Problematic Cellular Phone Use Questionnaire (PCPUQ) was used to identify problematic use of smartphone use, and Zung Self-Rating Anxiety Scale (SAS) and Zung Self-Rating Depression Scale (SDS) were used to measure anxiety and depression symptoms. [Results] The prevalence of PSU among undergraduates was estimated to be 20.6% (207/1 006). There were significant differences between PSU and non-PSU on their major of either science category or humanities category (χ2=11.424 ,P<0.01), grade (χ2=5.868 ,P<0.05), monthly living expense supported by their family (χ2=12.713 ,P<0.01), daily time spent on their smartphones (χ2=20.052, P<0.01), frequency of changing the mobile phones (χ2=14.511 ,P<0.01) and monthly smartphone bill (χ2=13.107, P< 0.01).

Following the recent changes to the diagnostic category for addictive disorders in DSM-5, it is urgent to clarify what constitutes behavioural addiction to have a clear direction for future research and classification. However, in the years following the release of DSM-5, an expanding body of research has increasingly classified engagement in a wide range of common behaviours and leisure activities as possible behavioural addiction. If this expansion does not end, both the relevance and the credibility of the field of addictive disorders might be questioned, which may prompt a dismissive appraisal of the new DSM-5 subcategory for behavioural addiction. We propose an operational definition of behavioural addiction together with a number of exclusion criteria, to avoid pathologizing common behaviours and provide a common ground for further research. The definition and its exclusion criteria are clarified and justified by illustrating how these address a number of theoretical and methodological shortcomings that result from existing conceptualizations. We invite other researchers to extend our definition under an Open Science Foundation framework. [less ▲]

Background and aims Despite many positive benefits, mobile phone use can be associated with harmful and detrimental behaviors. The aim of this study was twofold: to examine (a) cross-cultural patterns of perceived dependence on mobile phones in ten European countries, first, grouped in four different regions (North: Finland and UK; South: Spain and Italy; East: Hungary and Poland; West: France, Belgium, Germany, and Switzerland), and second by country, and (b) how socio-demographics, geographic differences, mobile phone usage patterns, and associated activities predicted this perceived dependence. Methods A sample of 2,775 young adults (aged 18-29 years) were recruited in different European Universities who participated in an online survey. Measures included socio-demographic variables, patterns of mobile phone use, and the dependence subscale of a short version of the Problematic Mobile Phone Use Questionnaire (PMPUQ; Billieux, Van der Linden, & Rochat, 2008). Results The young adults from the Northern and Southern regions reported the heaviest use of mobile phones, whereas perceived dependence was less prevalent in the Eastern region. However, the proportion of highly dependent mobile phone users was more elevated in Belgium, UK, and France. Regression analysis identified several risk factors for increased scores on the PMPUQ dependence subscale, namely using mobile phones daily, being female, engaging in social networking, playing video games, shopping and viewing TV shows through the Internet, chatting and messaging, and using mobile phones for downloading-related activities. Discussion and conclusions Self-reported dependence on mobile phone use is influenced by frequency and specific application usage. [less ▲]

Involvement in online sexual activities (OSAs) is ubiquitous, especially in males, and can under certain circumstances become problematic. The risk factors associated with problematic OSAs remain, however, poorly explored. The current study aimed to investigate the characteristics, usage patterns, and motives for men to engage in OSAs and to disentangle the risk factors associated with problematic OSAs. To this end, 434 men completed an online survey measuring socio-demographic information, OSAs consumption habits, motives for engaging in OSAs, symptoms of problematic OSAs, and sexual dysfunctions. Results showed that watching pornography is the most prevalent OSA, and sexual gratification is the most frequent motive for OSAs involvement. Additional multiple regression analyses indicated that the following characteristics are associated with problematic use of OSAs: (a) partnered-arousal activities (e.g., sex chat) and solitary-arousal activities (e.g., pornography); (b) anonymous fantasizing and mood regulation motives; and (c) higher sexual desire, lower overall sexual satisfaction, and lower erectile function. This study sheds new light on the characteristics, motives, and sexual function of men involved in OSAs, emphasizing that problematic OSAs are heterogeneous and depend on interrelated factors. The findings support tailoring of preventive actions and clinical interventions to both OSA type and individual risk factors. © 2015 Elsevier Ltd. All rights reserved. [less ▲]
