A systematic review and meta-analysis of risky decision-making in specific domains of problematic use of the internet: Evidence across different decision-making tasks. Neurosci Biobehav Rev 2023; 152:105271. [PMID: 37277009 DOI: 10.1016/j.neubiorev.2023.105271] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 06/01/2023] [Accepted: 06/02/2023] [Indexed: 06/07/2023]
Abstract
This systematic review summarizes empirical evidence on risky decision-making (objective risk and ambiguity) in specific domains of problematic use of the internet (PUI) focusing on online addictive behaviors. We conducted a pre-registered (PROSPERO: CRD42020188452) PubMed search for PUI domains: gaming, social-network use, online buying-shopping, online pornography use, and unspecified PUI. We used the Newcastle-Ottawa Scale for quality assessment. Relevant studies were identified only for gaming (n = 19), social-network use (n = 8), unspecified PUI (n = 7), and online gambling (n = 1). The meta-analyses included 25 studies (2498 participants) comparing PUI and control groups regarding decision-making performance under objective risk and ambiguity. Across PUI domains, individuals with PUI compared to control participants showed more disadvantageous decision-making in measures of objective risk (g = -0.42 [-0.69, -0.16], p = .002) but not ambiguity (g = -0.22 [-0.47, -0.04], p = .096). PUI domain and gender were significant moderators. In the risk domain, effects were particularly present in gaming disorder, especially in exclusively male samples. Overall, the paucity of empirical studies in the considered area necessitates further research to identify probable gender- and disorder-specific cognitive relationships.

Abstract
Human and artificial reasoning has to deal with uncertain environments. Ideally, probabilistic information is available. However, sometimes probabilistic information may not be precise or it is missing entirely. In such cases we reason with higher-order uncertainty. Formal argumentation is one of the leading formal methods to model defeasible reasoning in artificial intelligence, in particular in the tradition of Dung's abstract argumentation. Also from the perspective of cognition, reasoning has been considered as argumentative and social in nature, for instance by Mercier and Sperber. In this paper we use formal argumentation to provide a framework for reasoning with higher-order uncertainty. Our approach builds strongly on Haenni's system of probabilistic argumentation, but enhances it in several ways. First, we integrate it with deductive argumentation, both in terms of the representation of arguments and attacks, and in terms of utilizing abstract argumentation semantics for selecting some out of a set of possibly conflicting arguments. We show how our system can be adjusted to perform well under the so-called rationality postulates of formal argumentation. Second, we provide several notions of argument strength which are studied both meta-theoretically and empirically. In this way the paper contributes a formal model of reasoning with higher-order uncertainty with possible applications in artificial intelligence and human cognition.

Abstract
Abstract
Purpose of the Review
To provide a systematic review of experimental studies concerning cognitive functions in compulsive buying-shopping disorder (CBSD) and to evaluate the studies as supporting or not supporting the affective and cognitive interactions proposed by the Interaction of Person-Affect-Cognition-Execution (I-PACE) model for addictive behaviors.
Recent Findings
The results of the present review concerning CBSD mirror findings regarding cue reactivity and disadvantageous decision making in other addictive behaviors, but they also demonstrate a relative lack of experimental studies addressing other cognitive domains such as attentional bias, inhibitory control, implicit associations, or Pavlovian-to-instrumental transfer. Experimental work on physiological and neural correlates of affective and cognitive mechanisms and their interaction in CBSD is still at the beginning.
Summary
While a reasonable number of experimental neuropsychological studies support the application of the I-PACE framework to CBSD, future research is required to systematically examine affective and cognitive interactions in CBSD.

Abstract
When does repeated behaviour constitute behavioural addiction? There has been considerable debate about non-substance-related addictions and how to determine when impaired control over a behaviour is addiction. There are public health benefits to identifying new behavioural addictions if intervention can improve outcomes. However, criteria for establishing new behavioural addictions must guard against diagnostic inflation and the pathologizing of normal problems of living. Criteria should include clinical relevance (Criterion 1), alignment with addiction phenomenology (Criterion 2) and theory (Criterion 3), and taxonomic plausibility (Criterion 4). Against such criteria, evidence does not yet support classification of pornography-use and buying-shopping disorders as addictions.

Abstract
People with human immunodeficiency virus (HIV) often have neurocognitive impairment. People with HIV make riskier decisions when the outcome probabilities are known, and have abnormal neural architecture underlying risky decision making. However, ambiguous decision making, when the outcome probabilities are unknown, is more common in daily life, but the neural architecture underlying ambiguous decision making in people with HIV is unknown. Eighteen people with HIV and 20 controls completed a decision making task while undergoing functional magnetic resonance imaging scanning. Participants chose between a certain reward and uncertain reward with a known (risky) or unknown (ambiguous) probability of winning. There were three levels of risk: high, medium, and low. Ambiguous > risky brain activity was compared between groups. Ambiguous > risky brain activity was correlated with emotional/psychiatric functioning in people with HIV. Both groups were similarly ambiguity-averse. People with HIV were more risk-averse than controls and chose the high-risk uncertain option less often. People with HIV had hypoactivity in the precuneus, posterior cingulate cortex (PCC), and fusiform gyrus during ambiguous > medium risk decision making. Ambiguous > medium risk brain activity was negatively correlated with emotional/psychiatric functioning in individuals with HIV. To make ambiguous decisions, people with HIV underrecruit key regions of the default mode network, which are thought to integrate internally and externally derived information to come to a decision. These regions and related cognitive processes may be candidates for interventions to improve decision-making outcomes in people with HIV.

Longitudinal Changes in Gambling, Buying and Materialism in Adolescents: A Population-Based Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18062811.

Abstract
Gambling disorder, gambling-related cognitive biases, compulsive buying, and materialistic values lead to impaired functioning in important areas of life. The aims of the present longitudinal study are (1) to evaluate the change produced after one year in those mentioned variables and (2) to examine the gender role in these changes and to analyze the mediational mechanisms among the variables of the study. The sample was composed of 182 adolescents (103 females and 79 males) from secondary education Spanish institutions who completed self-administered questionnaires. Structural equation modeling has been used to explore associations between the different variables. Our results show significant decreases in compulsive buying, materialism, and cognitive biases related to gambling after one year. Gambling disorder severity was directly related to cognitive distortions of gambling and being a man. Compulsive buying was associated with older age and the female gender. Materialism was associated with compulsive buying and the male gender. In conclusion, gambling disorder, gambling-related cognitive biases, compulsive buying, and materialistic values change over time in different ways, according to gender. The understanding of gambling disorder and compulsive buying in adolescents could potentially lead to early prevention and treatment programs for the specific needs of gender and age.

Abstract
Objective To investigate associations between buying-shopping disorder (BSD) propensity and the performance in the Stroop Matching Task. This task measures stimulus interference, one specific component of behavioral impulsivity, using neutral (i.e. not buying related) stimuli. Deficits thus mirror a general rather than a specific deficit to resist task-irrelevant stimuli. Method 222 participants completed the Stroop Matching Task, the Pathological Buying Screener, and various questionnaires assessing clinical background variables as well as trait-impulsivity. Results Correlation analyses showed that BSD propensity was associated with poorer performance in the Stroop Matching Task. Multiple regression analyses controlling for related disorders and trait-impulsivity indicated that BSD was the only significant predictor. Conclusion These findings indicate that BSD propensity is associated with deficits in the stimulus interference component of behavioral impulsivity, mirroring a general cognitive deficit. Since no other disorder significantly predicted the performance in the Stroop Matching Task, this deficit seems to be unique for BSD.

Abstract
BACKGROUND Gambling and gaming disorders have been included as "disorders due to addictive behaviors" in the International Classification of Diseases (ICD-11). Other problematic behaviors may be considered as "other specified disorders due to addictive behaviors (6C5Y)." METHODS Narrative review, experts' opinions. RESULTS We suggest the following meta-level criteria for considering potential addictive behaviors as fulfilling the category of "other specified disorders due to addictive behaviors":1. Clinical relevance: Empirical evidence from multiple scientific studies demonstrates that the specific potential addictive behavior is clinically relevant and individuals experience negative consequences and functional impairments in daily life due to the problematic and potentially addictive behavior.2. Theoretical embedding: Current theories and theoretical models belonging to the field of research on addictive behaviors describe and explain most appropriately the candidate phenomenon of a potential addictive behavior.3. Empirical evidence: Data based on self-reports, clinical interviews, surveys, behavioral experiments, and, if available, biological investigations (neural, physiological, genetic) suggest that psychological (and neurobiological) mechanisms involved in other addictive behaviors are also valid for the candidate phenomenon. Varying degrees of support for problematic forms of pornography use, buying and shopping, and use of social networks are available. These conditions may fit the category of "other specified disorders due to addictive behaviors". CONCLUSION It is important not to over-pathologize everyday-life behavior while concurrently not trivializing conditions that are of clinical importance and that deserve public health considerations. The proposed meta-level-criteria may help guide both research efforts and clinical practice.

Abstract
BACKGROUND AND AIMS Internet addiction, sex addiction and compulsive buying are common behavioral problems, which share similarities with gambling disorder and substance use disorders. However, little is known about the efficacy of their treatments. The objective of this meta-analysis was to examine the efficacy of the treatments of such problem behaviors, and to draw parallels to gambling disorder and substance use disorders in terms of treatment response. METHODS Literature search yielded 91 studies totaling 3,531 participants to provide a comprehensive evaluation of the short-term and long-term efficacy of psychological, pharmacological and combined treatments for internet addiction, sex addiction, and compulsive buying. RESULTS Psychological, pharmacological, and combined treatments were associated with robust pre-post improvements in the global severity of internet addiction (Hedges's g: 1.51, 1.13, and 2.51, respectively) and sex addiction (Hedges's g: 1.09, 1.21, and 1.91, respectively). For compulsive buying, psychological and pharmacological treatments were also associated with a large-sized pre-post reduction in global severity (Hedges's g: 1.00 and 1.52, respectively). The controlled pre-post and within-group pre-follow-up effect sizes were in the similar range, with few exceptions. Moderator analyses suggest that psychological interventions are effective for reducing compulsive behaviors, especially when delivered face-to-face and conducted over extended periods of time. Combinations of cognitive-behavioral approaches with medications showed an advantage over monotherapies. DISCUSSION AND CONCLUSIONS The results suggest that treatments for common behavioral addictions are effective in the short term, similar to those implemented for gambling disorder and substance use disorders, but more rigorous clinical trials are needed.

Abstract
INTRODUCTION Decision making (DM) is one aspect of impulsivity that can be defined by the ability to decide between two or more options in a given situation. To date, there are at least two types of DM that differ in the level of uncertainty, and how much information about consequences is provided. In this study, we aimed to evaluate the two domains of DM - under risk and ambiguous - with a comprehensive evaluation in a group of patients with juvenile myoclonic epilepsy (JME), and correlate with patients' characteristics, clinical variables, and neuropsychological evaluation for executive functions. METHODS We evaluated 35 patients with JME and 39 healthy controls using the Iowa Gambling Task for DM under ambiguity and the Game Dice Task for DM under risk. We assessed the performance in Iowa Gambling Task and Game Dice Task through net scores, safe and risky choices, besides the type of decisions across time. RESULTS Patients with JME had a higher number of risky choices compared to controls in the Game Dice Task. There was no significant difference between patients and controls in the Iowa Gambling Task. However, patients with higher seizure frequency had worse scores on decks C and D (safe choices) from the Iowa Gambling Task. CONCLUSION Patients with JME have worse performance on DM under risk. The same was not observed for DM under ambiguity. Epilepsy-related factors and the presence of psychiatric disorders, but not executive dysfunction, were associated with a lower tendency for safe choices. These findings showed a dissociation between DM processes in patients with JME and a tendency to make disadvantageous decisions with measurable risks.

Addict Behav 2019; 96:82-88. [PMID: 31060009 DOI: 10.1016/j.addbeh.2019.04.008] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2018] [Revised: 03/14/2019] [Accepted: 04/12/2019] [Indexed: 12/01/2022]
Abstract
BACKGROUND AND AIMS Subjects with buying-shopping disorder (BSD) continue to buy offline as well as online despite negative consequences. Previous studies indicate that subjects with BSD show cue-reactivity and craving when exposed to shopping cues and have problems in long-term advantageous decision-making. The current study aimed at investigating the effect of online-shopping cues on decision-making, and whether addiction-relevant concepts such as cue-reactivity/craving and the symptom severity of BSD are related to decision-making. METHODS A non-clinical sample of 57 participants played a version of the modified Iowa Gambling Task (IGT), with online-shopping-related pictures shown either on the advantageous decks or on the disadvantageous decks (with control pictures on the opposing ones). Symptom severity of online-BSD and the craving to buy were assessed using questionnaires. In addition, the online-shopping pictures were rated concerning arousal, valence, and urge to buy. RESULTS The participants who played the IGT with the online-shopping pictures displayed on the disadvantageous decks performed significantly poorer than the other group with online-shopping pictures on the advantageous decks. The between-group differences were moderated by craving reactions and the symptom severity of online-BSD: When online-shopping pictures were displayed on the disadvantageous decks, this only interfered with IGT performance in participants who had high craving reactions towards shopping cues and/or high symptom severity of online-BSD. CONCLUSION Results indicate that exposure to online-shopping cues interferes with advantageous decision-making, especially in individuals with craving reactions and high symptoms of online-BSD. Results contribute to the question of why some people continue to buy despite negative consequences.

An experimental examination of cognitive processes and response inhibition in patients seeking treatment for buying-shopping disorder. PLoS One 2019; 14:e0212415.

Abstract
There is an ongoing debate about whether buying-shopping disorder (BSD) should be acknowledged as a behavioral addiction. The current study investigated if mechanisms that play a prominent role in disorders due to substance use or addictive behaviors are relevant in BSD, particularly cue reactivity, craving, cognitive bias and reduced inhibitory control regarding addiction-relevant cues. The study included 39 treatment-seeking patients with BSD and 39 healthy control (HC) participants (29 women and 10 men in each group). Subjective responses toward buying/shopping-relevant visual cues were compared in patients vs. control participants. Experimental paradigms with neutral and semi-individualized buying/shopping-related pictures were administered to assess attentional bias, implicit associations and response inhibition with respect to different visual cues: Dot-probe paradigm (DPP), Implicit Association Task (IAT), Go/nogo-task (GNG). The severity of BSD, craving for buying/shopping, and symptoms of comorbid mental disorders (anxiety, depressive and hoarding disorders) were measured using standardized questionnaires. The BSD-group showed more general craving for buying/shopping, stronger subjective craving reactions towards buying/shopping-related visual cues, and more symptoms of anxiety, depression and hoarding disorder than control participants. Task performance in the DPP, IAT and GNG paradigm did not differ between the two groups. The present findings confirm previous research concerning the crucial role of craving in BSD. The assumption that attentional bias, implicit associations and deficient inhibitory control with respect to buying/shopping-related cues are relevant in BSD could not be proven. Future research should address methodological shortcomings and investigate the impact of acute psychosocial stress and present mood on craving responses, cognitive processing, and response inhibition in patients with BSD.

Abstract
Introduction: Smartphone Addiction (SA) has caused negative consequences and functional impairments in college students, such as reduction of academic performance and impairment in sleep quality. Studies have shown that individuals with chemical and behavioral dependencies have a bias in decision-making process, which leads to short-term advantageous choices even if they cause long-term harm. This bias in decision-making process is accompanied by a change in somatic markers and is associated with the development and maintenance of addictive behavior. The decision-making process and the measurement of physiological parameters have not yet been analyzed in SA. The neuropsychological and physiological characterization of the SA can contribute to its approach with the other dependency syndromes and to its recognition as a disease. Objective: we aimed to evaluate the decision-making process under risk and under ambiguity in individuals with SA and to measure the physiological parameters that accompany this process. Method: We compared the performance in the Iowa Gambling Task (IGT), Game of Dice Task (GDT) and skin conductance response (SCR) between 50 individuals with SA and 50 controls. Results: Smartphone dependents presented a profile of impairment in decision-making under ambiguity, without impairment in decision-making under risk. They demonstrated lower SCR before disadvantageous choices, higher SCR after rewards and lower SCR after punishments during decision-making, which suggests difficulty in recognizing disadvantageous alternatives, high sensitivity to rewards, and low sensitivity to punishments. Conclusion: The impairment in the decision-making process in smartphone dependents is similar to that found in other chemical and behavioral addictions, such as alcohol addiction, gambling disorders and pathological buy. The impairment in decision under ambiguity with preservation of decision under risk may reflect dysfunction of implicit emotional processes without dysfunction of explicit cognitive process. This profile can contribute to the recognition of SA as a behavioral dependence and to guide specific preventive and therapeutic strategies.

Abstract
Many studies claim to measure decision-making under risk by employing the Domain-Specific Risk-Taking (DOSPERT) scale, a self-report measure, or the Balloon Analogue Risk Task (BART), a behavioural task. However, these tasks do not measure decision-making under risk but decision-making under uncertainty, a related but distinct concept. The present commentary discusses both the theoretical and empirical basis of the distinction between uncertainty and risk from the viewpoint of several scientific disciplines and reports how many studies wrongfully employ the DOSPERT scale and BART as risk-taking measures. Importantly, we call for proper distinguishing between (tasks measuring) decision-making under uncertainty and decision-making under risk in psychology, and related fields. We believe this is vital as research has shown that people’s attitudes, behaviour, and brain activity differ between both concepts, indicating that confusing the concepts may lead researchers to erroneous conclusions.

Abstract
BACKGROUND AND AIMS Pathological buying (PB) is often assumed to be related to deficits in impulse control. Distortions in judging elapsed time are one component of behavioral impulsivity. This study was set out to examine the hypothesis that PB propensity is associated with distorted time perception, such that time is perceived to pass more slowly. METHODS The study is based on a convenience sample of 78 adults. Symptom severity of PB and related problems/disorders (substance use, borderline, depression, mania, and obsessive-compulsive disorder) as well as four dimensions of trait impulsivity were assessed. A time-production task was employed that required participants to produce prespecified time intervals ranging from 1 to 60 s. RESULTS PB propensity was associated with the belief that time elapses more slowly, even when controlling for symptoms of related disorders and general trait impulsivity. Neither trait impulsivity nor symptoms of related disorders were predictive of distortions in judging elapsed time. DISCUSSION AND CONCLUSION These results suggest that PB propensity is related with non-specific, general deficits in judging elapsed time as a specific component of behavioral impulsivity.

Abstract
Great progress has been made in understanding how people make financial decisions. However, there is little research on how people make health and treatment choices. Our study aimed to examine how participants weigh benefits (reduction in disease progression) and probability of risk (medications' side effects) when making hypothetical treatment decisions, and to identify the neural networks implicated in this process. Fourteen healthy participants were recruited to perform a treatment decision probability discounting task using MRI. Behavioral responses and skin conductance responses (SCRs) were measured. A whole brain analysis were performed to compare activity changes between "mild" and "severe" medications' side effects conditions. Then, orbitofrontal cortex (OFC), ventral striatum (VS), amygdala and insula were chosen for effective connectivity analysis. Behavioral data showed that participants are more likely to refuse medication when side effects are high and efficacy is low. SCRs values were significantly higher when people made medication decisions in the severe compared to mild condition. Functionally, OFC and VS were activated in the mild condition and were associated with increased likehood of choosing to take medication (higher area under the curve "AUC" side effects/efficacy). These regions also demonstrated an increased effective connectivity when participants valued treatment benefits. By contrast, the OFC, insula and amygdala were activated in the severe condition and were associated with and increased likelihood to refuse treatment. These regions showed enhanced effective connectivity when participants were confronted with increased side effects severity. This is the first study to examine the behavioral and neural bases of medical decision making.

Abstract
BACKGROUND A number of neuropsychological alterations have been found in patients who have attempted suicide. Most studies investigating decision making (DM) abilities in suicide attempters so far have used one single DM task and included patients with a lifetime history of suicide attempts. These studies have yielded conflicting results. METHOD In this study, currently depressed in-patients who had a recent suicide attempt (within the last six months) (n = 21), depressed in-patients without a lifetime history of suicide attempts (n = 31) and a healthy control group (n = 26) were assessed with two tasks for the assessment of DM. The Game of Dice Task (GDT) measures DM under risk and the Iowa Gambling Task (IGT) DM under ambiguity. Further, depression severity, impulsiveness and suicidal intent of the current suicide attempt were assessed. RESULTS Both depressed groups differed from controls with respect to marital and partnership status, smoking, impulsiveness and psychiatric family history. In terms of DM, IGT scores did not differ significantly between groups. However, suicide attempters made significantly more risky decisions as assessed with the GDT than both control groups (p < 0.05 for pairwise comparisons, p = 0.065 for overall comparison of the 3 groups). LIMITATIONS The available tasks assess DM under laboratory conditions which may not reflect the emotional status of suicidal individuals. No general cognitive assessment was included. CONCLUSIONS Depressed suicide attempters differed with regard to DM under risk but not DM under ambiguity. When studying DM it appears crucial to take varying aspects of DM into account.

Abstract
Background and aims Internet addiction (IA) was recently defined as a disorder tagging both the impulse control and the reward systems. Specifically, inhibitory deficits and reward bias were considered highly relevant in IA. This research aims to examine the electrophysiological correlates and autonomic activity [skin conductance response (SCR) and heart rate] in two groups of young subjects (N = 25), with high or low IA profile [tested by the Internet Addiction Test (IAT)], with specific reference to gambling behavior. Methods Oscillatory brain activity (delta, theta, alpha, beta, and gamma) and autonomic and behavioral measures [response times (RTs) and error rates (ERs)] were acquired during the performance of a Go/NoGo task in response to high-rewarding (online gambling videos and video games) or neutral stimuli. Results A better performance (reduced ERs and reduced RTs) was revealed for high IAT in the case of NoGo trials representing rewarding cues (inhibitory control condition), probably due to a "gain effect" induced by the rewarding condition. In addition, we also observed for NoGo trials related to gambling and video games stimuli that (a) increased low-frequency band (delta and theta) and SCR and (b) a specific lateralization effect (more left-side activity) delta and theta in high IAT. Discussion Both inhibitory control deficits and reward bias effect were considered to explain IA.

Risky decision-making under risk in schizophrenia: A deliberate choice? J Behav Ther Exp Psychiatry 2017; 56:57-64.

Abstract
BACKGROUND AND OBJECTIVES Patients with schizophrenia reveal impaired decision-making strategies causing social, financial and health care problems. The extent to which deficits in decision-making reflect intentional risky choices in schizophrenia is still under debate. Based on previous studies we expected patients with schizophrenia to reveal a riskier performance on the GDT and to make more disadvantageous decisions on the IGT. METHODS In the present study, we investigated 38 patients with schizophrenia and 38 matched healthy control subjects with two competing paradigms regarding feedback: (1) The Game of Dice Task (GDT), in which the probabilities of winning or losing are stable and explicitly disclosed to the subject, to assess decision-making under risk and (2) the Iowa Gambling Task (IGT), which requires subjects to infer the probabilities of winning or losing from feedback, to investigate decision-making under ambiguity. RESULTS Patients with schizophrenia revealed an overall riskier performance on the GDT; although they adjusted their strategy over the course of the GDT, they still made significantly more disadvantageous choices than controls. More positive symptoms in patients with schizophrenia indicated by higher PANSS positive scores were associated with riskier choices and less use of negative feedback. Compared to healthy controls, they were not impaired in net score but chose more disadvantageous cards than controls on the first block of the IGT. LIMITATIONS Effects of medication at the time of testing cannot be ruled out. CONCLUSIONS Our findings suggest that patients with schizophrenia make riskier decisions and are less able to regulate their decision-making to implement advantageous strategies, even when the probabilities of winning or losing are explicitly disclosed. The dissociation between performance on the GDT and IGT suggests a pronounced impairment of executive functions related to the dorsolateral prefrontal cortex.

Abstract
We investigated decision-making under ambiguity (DM-UA) and decision making under risk (DM-UR) in individuals with premanifest and manifest Huntington's disease (HD). Twenty individuals with premanifest HD and 23 individuals with manifest HD, on one hand, and 39 healthy individuals divided into two control groups, on the other, undertook a modified version of the Iowa Gambling Task (IGT), an adaptation of a DM-UA task, and a modified version of the Game of Dice Task (GDT), an adaptation of a DM-UR task. Participants also filled in a questionnaire of impulsivity and responded to cognitive tests specifically designed to assess executive functions. Compared to controls, individuals with premanifest HD were unimpaired in performing executive tests as well as in decision-making tasks, except for the Stroop task. In contrast, individuals with manifest HD were impaired in both the IGT and executive tasks, but not in the GDT. No sign of impulsivity was observed in individuals with premanifest or manifest HD. Our results suggest that the progression of HD impairs DM-UA without affecting DM-UR, and indicate that decision-making abilities are preserved during the premanifest stage of HD.

Abstract
We report the development and validation of a scale to measure online shopping addiction. Inspired by previous theories and research on behavioral addiction, the Griffiths's widely accepted six-factor component model was referred to and an 18-item scale was constructed, with each component measured by three items. The results of exploratory factor analysis, based on Sample 1 (999 college students) and confirmatory factor analysis, based on Sample 2 (854 college students) showed the Griffiths's substantive six-factor structure underlay the online shopping addiction scale. Cronbach's alpha suggested that the resulting scale was highly reliable. Concurrent validity, based on Sample 3 (328 college students), was also satisfactory as indicated by correlations between the scale and measures of similar constructs. Finally, self-perceived online shopping addiction can be predicted to a relatively high degree. The present 18-item scale is a solid theory-based instrument to empirically measure online shopping addiction and can be used for understanding the phenomena among young adults.

Abstract
Pathological buying is characterized by irrepressible buying behaviour and its negative consequences. A possible mechanism contributing to its development and maintenance is that buying episodes act as a maladaptive strategy to cope with negative emotions. Accordingly, pathological buying has been repeatedly associated with impulsivity, in particular with the tendency to experience strong reactions under negative affect. Relying on an experimental mood induction procedure, the present study tested in a sample of 100 individuals (a) whether individuals with pathological buying symptoms respond more impulsively in the Go/No-Go Task (as a measure of the behavioural inhibition aspect of impulsivity) and (b) whether this association is more pronounced in a negative mood. While controlling for comorbidities, the results show that pathological buying is associated with faster responses and a larger number of commission errors. Moreover, a significant interaction indicated that the association between pathological buying and performance the Go/No-Go Task was stronger in the negative mood condition. The present study thus shows that pathological buying is associated with deficits in the behavioural inhibition component of impulsivity. These deficits are most pronounced when mood is negative; in turn, this provides an explanation for the occurrence of excessive buying episodes following negative affect.

Abstract
Aim To investigate impulsive behaviors in pathological buying (PB). Methods The study included three groups matched for age and gender: treatment seeking outpatients with PB (PB+), treatment seeking psychiatric inpatients without PB (PB-), and a healthy control group (HC). PB was assessed by means of the Compulsive Buying Scale and by the impulse control disorder (ICD) module of the research version of the Structured Clinical Interview for DSM-IV (SCID-ICD). All participants answered questionnaires concerning symptoms of borderline personality disorder, self-harming behaviors, binge eating and symptoms of attention deficit and hyperactivity disorder (ADHD). In addition, comorbid ICDs were assessed using the SCID-ICD. Results The PB+ and PB- groups did not differ with regard to borderline personality disorder or ADHD symptoms, but both groups reported significantly more symptoms than the HC group. Frequencies of self-harming behaviors did not differ between the three groups. Patients with PB were more often diagnosed with any current ICD (excluding PB) compared to those without PB and the HC group (38.7% vs. 12.9% vs. 12.9%, respectively, p=.017). Discussion Our findings confirm prior research suggesting more impulsive behaviors in patients with and without PB compared to healthy controls. The results of the questionnaire-based assessment indicate that outpatients with PB perceive themselves equally impulsive and self-harm as frequently as inpatients without PB; but they seem to suffer more often from an ICD as assessed by means of an interview.
