326 to 350 of 620Assessing the Relationship Between the Type of Internet Use and Internet Addiction in Early and Middle Adolescents: Cross-Sectional Study From Qatar.
Background: With the increasing prevalence of digital technology, adolescent internet addiction (IA) has become a global concern. Excessive internet use, especially among adolescents, has been linked to various negative outcomes such as poor academic performance, social isolation, and mental health issues. Conducted among adolescents of Arab origin, our study addressed the limitations of the literature, which predominantly focuses on Western, educated, industrialized, rich, and democratic populations.
Objective: This study aimed to differentiate between essential and nonessential internet use and how they relate to IA in early and middle adolescents, as well as the relationship between subjective happiness with the amount of time spent on nonessential internet use and IA.
Methods: A cross-sectional survey was conducted among 377 students from 16 schools in Qatar. The survey measured esse…

Attenuated Directed Exploration during Reinforcement Learning in Gambling Disorder.
Gambling disorder (GD) is a behavioral addiction associated with impairments in value-based decision-making and behavioral flexibility and might be linked to changes in the dopamine system. Maximizing long-term rewards requires a flexible trade-off between the exploitation of known options and the exploration of novel options for information gain. This exploration-exploitation trade-off is thought to depend on dopamine neurotransmission. We hypothesized that human gamblers would show a reduction in directed (uncertainty-based) exploration, accompanied by changes in brain activity in a fronto-parietal exploration-related network. Twenty-three frequent, non-treatment seeking gamblers and twenty-three healthy matched controls (all male) performed a four-armed bandit task during functional magnetic resonance imaging (fMRI). Computational modeling using hierarchical Bayesian parameter estimat…

The contributions of social comparison to social network site addiction.
Excessive use of social network sites (SNSs) can often lead to negative consequences of frequent upward social comparisons despite having the social network platform to present users in a favorable light. However, the existing literature gives little evidence to social comparison related antecedents and consequents of uncontrollable use of SNSs. The present study aimed to investigate the contributions of social comparison to SNS addiction. In Study 1, using a convenient sample in Austria (n = 103), we showed that the tendency to engage in social comparisons of ability (but not of opinion) predicted self-reported SNS addiction over and above the feelings of relative deprivation on social support and status. SNS addiction mediated the relations between social comparison of ability and stress, but not self-esteem. In Study 2, using a broad sample of participants in Austria (n = 500), we rep…

Impulsivity is a multidimensional construct. Although gambling disorder (GD) has been associated with high impulsivity, impulsivity across multiple domains has not been thoroughly investigated in this population. We first aimed to examine whether associations between three facets of impulsivity (response impulsivity, choice impulsivity and impulsive tendency) varied between GD patients and healthy controls (HC). We next aimed to evaluate relationships between these three types of impulsivity, as proposed by theoretical models of impulsivity, and their associations with GD severity. The sample included 97 treatment-seeking adult men with GD, diagnosed according to DSM-5 criteria, and 32 male HCs recruited from the general population. Greater impulsivity in all three domains was found in men with GD in comparison to men without GD. Associations between impulsivity facets were found in both…

Cognitive dynamics of intertemporal choice in gambling disorder.
Gambling Disorder (GD) is a behavioral addiction characterized by the persistence of recurrent gambling behaviors despite serious adverse consequences. One of the key features of GD is a marked inability to delay gratification and an overall impairment of decision-making mechanisms. Indeed, in intertemporal choice (ITC) tasks, GD patients usually display a marked tendency to prefer smaller-sooner over larger-later rewards (temporal discounting, TD). However, ITC represents a highly verbal/explicit measure, and as such it might not be sensitive to implicit decision biases. Here we sought to uncover the implicit mechanisms underlying the ITC impairment in GD by employing the process-tracing method of mouse kinematics. To this aim, we collected and analyzed ITCs and kinematics measures from 24 GD patients and 23 matched healthy control participants (HC). In line with the relevant literature…

Problem gambling and suicidality in England: secondary analysis of a representative cross-sectional survey.
Objectives: Problem gamblers in treatment are known to be at high risk for suicidality, but few studies have examined if this is evident in community samples. Evidence is mixed on the extent to which an association between problem gambling and suicidality may be explained by psychiatric comorbidity. We tested whether they are associated after adjustment for co-occurring mental disorders and other factors.
Study design: Secondary analysis of the Adult Psychiatric Morbidity Survey 2007, a cross-sectional national probability sample survey of 7403 adults living in households in England.
Methods: Rates of suicidality in problem gamblers and the rest of the population were compared. A series of logistic regression models assessed the impact of adjustment on the relationship between problem gambling and suicidality.
Results: Past year suicidality was reported in 19.2% of problem gamblers, comp…

Prior Exposure to Salient Win-Paired Cues in a Rat Gambling Task Increases Sensitivity to Cocaine Self-Administration and Suppresses Dopamine Efflux in Nucleus Accumbens: Support for the Reward Deficiency Hypothesis of Addiction.
Rats trained to perform a version of the rat gambling task (rGT) in which salient audiovisual cues accompany reward delivery, similar to commercial gambling products, show greater preference for risky options. Given previous demonstrations that probabilistic reinforcement schedules can enhance psychostimulant-induced increases in accumbal DA and locomotor activity, we theorized that performing this cued task could perpetuate a proaddiction phenotype. Significantly more rats developed a preference for the risky options in the cued versus uncued rGT at baseline, and this bias was further exacerbated by cocaine self-administration, whereas the choice pattern of optimal decision-makers was unaffected. The addition of reward-paired cues therefore increased the proportion of rats exhibiting a maladaptive cognitive response to cocaine self-administration. Risky choice was not associated with re…

Although behavioral addictions share many clinical features with drug addictions, they show strikingly large variation in their behavioral phenotypes (such as in uncontrollable gambling or eating). Neurotransmitter function in behavioral addictions is poorly understood, but has important implications in understanding its relationship with substance use disorders and underlying mechanisms of therapeutic efficacy. Here, we compare opioid and dopamine function between two behavioral addiction phenotypes: pathological gambling (PG) and binge eating disorder (BED). Thirty-nine participants (15 PG, 7 BED, and 17 controls) were scanned with [11C]carfentanil and [18F]fluorodopa positron emission tomography using a high-resolution scanner. Binding potentials relative to non-displaceable binding (BPND) for [11C]carfentanil and influx rate constant (Ki) values for [18F]fluorodopa were analyzed with…

Current suicidal ideation in treatment-seeking individuals in the United Kingdom with gambling problems.
Background: Studies show higher lifetime prevalence of suicidality in individuals with pathological gambling. However, less is known about the relationship between pathological gambling and current suicidal ideation.
Objectives: We investigated socio-demographic, clinical and gambling-related variables associated with suicidality in treatment-seeking individuals.
Methods: Bivariate analyses and logistic regression models were generated on data from 903 individuals to identify measures associated with aspects of suicidality.
Results: Forty-six percent of patients reported current suicidal ideation. People with current suicidal thoughts were more likely to report greater problem-gambling severity (p<0.001), depression (p<0.001) and anxiety (p<0.001) compared to those without suicidality. Logistic regression models suggested that past suicidal ideation (p<0.001) and higher anxiety (p<0.05) …

Gambling Disorder and Affect Regulation: The Role of Alexithymia and Attachment Style.
The aim of the present study was to explore the dimensions of alexithymia and attachment styles in a group of disordered gamblers and to evaluate the relationship between alexithymia, attachment styles, and the severity of gambling disorder. Sixty disordered gamblers diagnosed according to the diagnostic and statistical manual-5 filled out the Kurzfragebogen zum Glücksspielverhalten, the 20-Item Toronto Alexithymia Scale, and the Experiences in Close Relationships-Revised. Approximately 70 % of the sample displayed 'intermediate' and 'severe' gambling severity levels on the Kurzfragebogen zum Glücksspielverhalten, and 77 % showed 'high' or 'borderline' levels of alexithymia on the Toronto Alexithymia Scale (mean = 56.40). Regarding attachment styles, 70 % of the sample displayed an 'insecure' attachment, with a particularly high prevalence of the 'fearful' style (26.66 %). A linear regre…

Background: Impulsivity is understood to be a multidimensional construct involving aspects such as impulsive choice and impulsive traits. Delay discounting, the tendency to place greater value in immediate rewards over larger, long-term rewards, has been associated with maladaptive choices in gambling disorder (GD). Delay discounting is known to evolve with age; though no study to date has evaluated the interactions between impulsivity, GD severity and age in treatment-seeking patients.
Objectives: We aimed to examine whether associations between delay discounting and impulsivity traits differed between younger and older-aged GD patients. Secondly, we sought to untangle the mediating role of impulsivity in determining gambling behavior in these two age groups.
Methods: GD patients (N=335) were evaluated using the UPPS-P Impulsive Behavior Scale and a delay discounting task. Structural Eq…

Addiction severity pattern associated with adult and childhood Attention Deficit Hyperactivity Disorder (ADHD) in patients with addictions.
Attention Deficit Hyperactivity Disorder (ADHD) is highly prevalent among adults with addictive disorders, but little is known about addiction patterns associated with ADHD diagnosis. This study examined addiction severity in patients with co-occurring addictive disorders and ADHD controlling for the potential influence of associated psychiatric comorbidity. Data were collected in French outpatient addiction treatment centers. A total of 217 patients seeking treatment for substance or gambling addiction were included. At treatment entry, participants were interviewed with the Addiction Severity Index, the Conners Adult ADHD Diagnosis Interview for the DSM-IV (CAADID), the Mini International Neuropsychiatric Interview (MINI) and the Structured Clinical Interview for DSM-IV Axis II for borderline personality disorder (SCID II). History of ADHD was associated with an earlier onset of addict…

An empirical study of gender differences in online gambling.
Gambling has typically been considered a predominately male activity. However, recent prevalence surveys have shown greater numbers of females are now gambling. Much of the gambling literature suggests online gamblers are more likely to be male, and that problem gamblers are more likely to be male. Males and females are also likely to be gambling for different reasons and have a preference for different gambling activities. Little is known about the pattern of play among female online gamblers. The aim of this survey was to develop a better profile of female online gamblers and to examine any gender differences between males and females in terms of how and why they gamble online, their frequency of online gambling, patterns of play, as well as attitudes to online gambling. The survey was posted on 32 international online gambling websites and was completed by 975 online gamblers (includi…

Aims: Pathological gambling (PG) shares diagnostic features with substance use disorder (SUD), but the neurochemical mechanisms underlying PG are poorly understood. Because dopamine (DA), a neurotransmitter implicated in reward and reinforcement, is probably involved, we used positron emission tomography (PET) to test whether PG is associated with abnormalities in D2 and D3 receptor levels, as observed in SUD.
Design: Case-control study comparing PG to healthy control (HC) subjects.
Setting: Academic research imaging centre.
Participants: Thirteen non-treatment-seeking males meeting DSM-IV criteria for PG, and 12 matched HC (11 of whom completed PET).
Measurements: Two PET scans (one with the D3 receptor preferring agonist [11C]-(+)-propyl-hexahydro-naphtho-oxazin (PHNO) and the other with [11C]raclopride) to assess D(2/3) DA receptor availability, and behavioural measures (self-report q…

Excessive Internet gaming and decision making: do excessive World of Warcraft players have problems in decision making under risky conditions?
The dysfunctional behavior of excessive Internet gamers, such as preferring the immediate reward (to play World of Warcraft) despite the negative long-term consequences may be comparable with the dysfunctional behavior in substance abusers or individuals with behavioral addictions, e.g. pathological gambling. In these disorders, general decision-making deficits have been demonstrated. Hence, the aim of the present work was to examine decision-making competences of excessive World of Warcraft players. Nineteen excessive Internet gamers (EIG) and a control group (CG) consisting of 19 non-gamers were compared with respect to decision-making abilities. The Game of Dice Task (GDT) was applied to measure decision-making under risky conditions. Furthermore psychological-psychiatric symptoms were assessed in both groups. The EIG showed a reduced decision-making ability in the GDT. Furthermore th…

Coping with guilt and shame after gambling loss.
In this study we examined the relations between guilt and shame and coping strategies in response to gambling loss. Based on H.B. Lewis's (Shame & guilt in neurosis. New York: International Universities Press, 1971) account of guilt and shame, we proposed that unlike guilt, the experience of shame involves the attribution of gambling loss to stable and global internal factors (i.e., self-devaluation). We hypothesized that problem gambling severity would be more strongly associated with the intensity of shame than with the intensity of guilt following gambling loss. Further, we hypothesized that the intensity of shame would be positively associated with the use of avoidant coping strategies following gambling loss. Finally, we hypothesized that the intensity of shame would mediate the association between problem gambling severity and the use of avoidant coping. These hypotheses were suppo…

Problem gambling and intimate partner violence.
This study examined the prevalence and severity of intimate partner violence (IPV) among 248 problem gamblers (43 women, 205 men) recruited from newspaper advertisements. The main outcome measures used were the Canadian Problem Gambling Index, the Conflicts Tactics Scale-2, the State Trait Anger Expression Inventory-2, the drug and alcohol section of the Addiction Severity Index and the substance use section of the Structured Clinical Interview for the DSM-IV. In this sample, 62.9% of participants reported perpetrating and/or being the victims of IPV in the past year, with 25.4% reporting perpetrating severe IPV. The majority of the sample (64.5%) also had clinically significant anger problems, which was associated with an increased risk of being both the perpetrator and victim of IPV. The presence of a lifetime substance use disorder among participants who had clinically significant ang…

Gambling problems in the family--a stratified probability sample study of prevalence and reported consequences.
Background: Prior studies on the impact of problem gambling in the family mainly include help-seeking populations with small numbers of participants. The objective of the present stratified probability sample study was to explore the epidemiology of problem gambling in the family in the general population.
Methods: Men and women 16-74 years-old randomly selected from the Norwegian national population database received an invitation to participate in this postal questionnaire study. The response rate was 36.1% (3,483/9,638). Given the lack of validated criteria, two survey questions ("Have you ever noticed that a close relative spent more and more money on gambling?" and "Have you ever experienced that a close relative lied to you about how much he/she gambles?") were extrapolated from the Lie/Bet Screen for pathological gambling. Respondents answering "yes" to both questions were defined…

A national study of neighbourhood access to gambling opportunities and individual gambling behaviour.
Objective: To investigate associations between neighbourhood accessibility to gambling outlets (non-casino gaming machine locations, sports betting venues and casinos) and individual gambling behaviour in New Zealand.
Design: A Geographical Information Systems (GIS) measure of neighbourhood access to gambling venues. Two-level logistic regression models were fitted to examine the effects of neighbourhood access on individual gambling behaviour after controlling for potential individual- and neighbourhood-level confounding factors.
Setting: 38,350 neighbourhoods across New Zealand.
Participants: 12,529 respondents of the 2002/03 New Zealand Health Survey.
Results: Compared with those living in the quartile of neighbourhoods with the furthest access to a gambling venue, residents living in the quartile of neighbourhoods with the closest access were more likely (adjusted for age, sex, socio…

Epidemiological associations between gambling behavior, substance use & mood and anxiety disorders.
Objective: To compare gambling behaviors in a random sample of community residents with and without mental disorders identified by the Composite International Diagnostic Interview (CIDI).
Method: A large national community survey conducted by Statistics Canada included questions about problems arising from gambling activities as per the Canadian Problem Gambling Index (CPGI). We compared respondents within three gambling severity categories (non-problem, low severity and moderate/high severity gambling) across three diagnostic groupings (mood/anxiety disorders, substance dependence/harmful alcohol use, no selected psychiatric disorder).
Results: Of the 14,934 respondents age 18-64 years who engaged in at least one type of gambling activity in the previous 12 months, 5.8% fell in the low severity gambling category while 2.9% fell in the moderate/high severity category. Females accounted f…

Addiction, Anhedonia, and Comorbid Mood Disorder. A Narrative Review.
Background: Recently, anhedonia has been recognized as an important Research Domain Criterion (RDoC) by the National Institute of Mental Health. Anhedonia is proposed to play an essential role in the pathogenies of both addictive and mood disorders, and possibly their co-occurrence with a single individual. However, up to now, comprehensive information about anhedonia concerning its underlying neurobiological circuitries, the neurocognitive correlates, and their role in addiction, mood disorder, and comorbidity remains scarce. Aim: In this literature review of human studies, we bring together the current state of knowledge with respect to anhedonia in its relationship with disorders in the use of substances (DUS) and the comorbidity with mood disorders. Method: A PubMed search was conducted using the following search terms: (Anhedonia OR Reward Deficiency) AND ((Drug Dependence OR Abuse)…

Television and video game exposure and the development of attention problems.
Objectives: Television viewing has been associated with greater subsequent attention problems in children. Few studies have examined the possibility of a similar association between video games and attention problems, and none of these has used a longitudinal design.
Methods: A sample of 1323 middle childhood participants were assessed during a 13-month period by parent- and child-reported television and video game exposure as well as teacher-reported attention problems. Another sample of 210 late adolescent/early adult participants provided self-reports of television exposure, video game exposure, and attention problems.
Results: Exposure to television and video games was associated with greater attention problems. The association of television and video games to attention problems in the middle childhood sample remained significant when earlier attention problems and gender were statis…

Pharmacologic Management of Skin-Picking Disorder: An Updated Review.
Introduction: Skin-picking disorder (SPD), defined as a psychocutaneous condition that involves excessive picking at the skin causing marked impairment in quality of life, is commonly seen in both dermatology and psychiatry. As such, therapeutic intervention-both nonpharmacologic and pharmacologic-is essential. Given the rising prevalence of SPD and the tremendous impact it can have on quality of life, an updated review, specifically on pharmacologic options, is very much needed.
Objective: The aim of this scoping review is to provide a detailed compilation of updated pharmacologic treatments for SPD based on evidence from recent studies and trials.
Methods: A search through PubMed was conducted using the key words "treatment" and "skin picking" or "excoriation" in November 2024. Articles were limited to those that solely address pharmacologic treatments in skin-picking for individuals o…

Impulse control disorders (ICDs) and related impulsive and compulsive behaviors (together called ICBs) have been increasingly recognized in the context of Parkinson's disease (PD) and treatment. The International Parkinson's and Movement Disorder Society commissioned a task force to assess available clinical screening instruments and rating scales, including their clinimetric properties, make recommendations regarding their utility, and suggest future directions in scale development and validation. The literature was systematically searched for scales measuring a range of reported ICBs in PD. A scale was designated "recommended" if the scale had been employed in PD studies, been used beyond the group that developed it, and had adequate clinimetric data published for PD. Numerous diagnostic screening tools and severity rating scales were identified for a range of ICBs, including compulsiv…

Impulse Control and Related Disorders in Parkinson's Disease.
Impulse control disorders (ICDs), such as compulsive gambling, buying, sexual, and eating behaviors, are a serious and increasingly recognized complication in Parkinson's disease (PD), occurring in up to 20% of PD patients over the course of their illness. Related behaviors include punding (stereotyped, repetitive, purposeless behaviors), dopamine dysregulation syndrome (DDS) (compulsive medication overuse), and hobbyism (e.g., compulsive internet use, artistic endeavors, and writing). These disorders have a significant impact on quality of life and function, strain interpersonal relationships, and worsen caregiver burden, and are associated with significant psychiatric comorbidity. ICDs have been most closely related to the use of dopamine agonists (DAs), while DDS is primarily associated with shorter acting, higher potency dopamine replacement therapy (DRT), such as levodopa. However, …
