Integrating psychological and neurobiological considerations regarding the development and maintenance of specific Internet-use disorders: An Interaction of Person-Affect-Cognition-Execution (I-PACE) model

Neuroscience & Biobehavioral Reviews, Journal Year: 2016, Volume and Issue: 71, P. 252 - 266

Published: Sept. 6, 2016

Within the last two decades, many studies have addressed clinical phenomenon of Internet-use disorders, with a particular focus on Internet-gaming disorder. Based previous theoretical considerations and empirical findings, we suggest an Interaction Person-Affect-Cognition-Execution (I-PACE) model specific disorders. The I-PACE is framework for processes underlying development maintenance addictive use certain Internet applications or sites promoting gaming, gambling, pornography viewing, shopping, communication. composed as process model. Specific disorders are considered to be consequence interactions between predisposing factors, such neurobiological psychological constitutions, moderators, coping styles Internet-related cognitive biases, mediators, affective responses situational triggers in combination reduced executive functioning. Conditioning may strengthen these associations within addiction process. Although hypotheses regarding mechanisms summarized model, must further tested empirically, implications treatment interventions suggested.

The Interaction of Person-Affect-Cognition-Execution (I-PACE) model for addictive behaviors: Update, generalization to addictive behaviors beyond internet-use disorders, and specification of the process character of addictive behaviors

Neuroscience & Biobehavioral Reviews, Journal Year: 2019, Volume and Issue: 104, P. 1 - 10

Published: June 24, 2019

We propose an updated version of the Interaction Person-Affect-Cognition-Execution (I-PACE) model, which we argue to be valid for several types addictive behaviors, such as gambling, gaming, buying-shopping, and compulsive sexual behavior disorders. Based on recent empirical findings theoretical considerations, that behaviors develop a consequence interactions between predisposing variables, affective cognitive responses specific stimuli, executive functions, inhibitory control decision-making. In process associations cue-reactivity/craving diminished contribute development habitual behaviors. An imbalance structures fronto-striatal circuits, particularly ventral striatum, amygdala, dorsolateral prefrontal areas, may relevant early stages dorsal striatum later processes. The I-PACE model provide foundation future studies clinical practice. Future should investigate common unique mechanisms involved in addictive, obsessive-compulsive-related, impulse-control, substance-use

Impulsivity in Gambling Disorder and problem gambling: a meta-analysis

Neuropsychopharmacology, Journal Year: 2019, Volume and Issue: 44(8), P. 1354 - 1361

Gambling Disorder is a prevalent psychiatric condition often linked to dysfunction of cognitive domains regulating impulsive behavior. Despite the centrality impulsivity neurobiological models Disorder, comprehensive meta-analysis all has yet be conducted. It also not clear whether deficits in extend those with problem (at-risk) gambling. A systematic review was undertaken case-control studies examining following or at-risk (problem) gambling: attentional inhibition, motor discounting, decision-making, and reflection impulsivity. Case-control differences cognition were identified using (random-effects modeling). Moderation analysis explored potential influences age, gender, presence/absence comorbidities cases, geographical region, study quality on performance. associated significant impairments (g = 0.39-0.48) 0.55) discounting 0.66), decision-making 0.63) tasks.

The prevalence of gambling and problematic gambling: a systematic review and meta-analysis

The Lancet Public Health, Journal Year: 2024, Volume and Issue: 9(8), P. e594 - e613

Background Gambling behaviours have become of increased public health interest, but data on prevalence remain scarce.In this study, we aimed to estimate for adults and adolescents the any gambling activity, engaging in specific activities, risk problematic gambling, by activity. MethodsWe performed a systematic review meta-analysis.We systematically searched peer-reviewed literature (on MEDLINE, Embase, PsycInfo) grey identify papers published between Jan 1, 2010, March 4, 2024.We including engagement with individual among adolescents.We included that reported or proportion outcome interest.We excluded non-original based biased sample.Data were extracted into bespoke Microsoft Access database, Joanna Briggs Institute Critical Appraisal Tool used bias each sample.Representative population survey estimates firstly meta-analysed country-level estimates, using metaprop, activity.Secondly, population-weighted regional-level global generated activity.This is registered PROSPERO (CRD42021251835).Findings We screened 3692 reports, 380 representative unique samples, 68 countries territories.Overall, samples consisted slightly more men male individuals, mean age 29•72 years, most identified from high-income countries.Of these 366 meta-analysis.Globally, 46•2% (95% CI 41•7-50•8) 17•9% (14•8-21•2) had gambled past 12 months.Rates higher (49•1%; 45•5-52•6) than women (37•4%; 32•0-42•5).Among adults, 8•7% (6•6-11•3) classified as 1•41% (1•06-1•84) gambling.Among rates greatest online casino slots (15•8%; 10•7-21•6).There few adolescent samples.Interpretation Existing evidence suggests prevalent globally, substantial engage are those formats.Given growth industry association range harms, governments need give greater attention strict regulation monitoring globally.

Meta-analyses of clinical neuropsychological tests of executive dysfunction and impulsivity in alcohol use disorder

The American Journal of Drug and Alcohol Abuse, Journal Year: 2016, Volume and Issue: 43(1), P. 24 - 43

Published: Aug. 12, 2016

Background: Promising models for cognitive rehabilitation in alcohol treatment rest on a more nuanced understanding of the associated impairments multifaceted domains executive functioning (EF) and impulsivity. Objectives: This meta-analysis examined effects individual subcomponents EF impulsivity recently detoxified participants, including 1) Inhibition & Self-Regulation, 2) Flexibility Set Shifting, 3) Planning Problem Solving, 4) Reasoning Abstraction, 5) Verbal Fluency. Impulsivity was further through an analysis motor, cognitive, decisional subcategories. Method: Investigators searched, coded, calculated effect sizes demonstrated broad range neuropsychological tests EF. A total 77 studies were selected covering 48 years research with sample size 5140. Results: Findings ranged from Hedges' g 0.803 to 0.359 Results also varied subcategories Inhibition, large (g = 0.817) (0.860), moderate motor 0.529). The Hayling Test, Wisconsin Card Sorting Iowa Gambling Task measures most sensitive effects. Conclusion: Planning, problem solving, inhibitory abilities are significantly affected by abuse, forms impacted. Cognitive remediation targeting these deficits might increase related functions that mediate ability or abstain alcohol, so lead improved results.

Compulsivity-related neurocognitive performance deficits in gambling disorder: A systematic review and meta-analysis

Neuroscience & Biobehavioral Reviews, Journal Year: 2017, Volume and Issue: 84, P. 204 - 217

Published: Dec. 6, 2017

Compulsivity is a core feature of addictive disorders, including gambling disorder. However, it unclear to what extent this compulsive behavior in disorder associated with abnormal compulsivity-related neurocognitive functioning. Here, we summarize and synthesize the evidence for behavior, as assessed by tasks, individuals compared healthy controls (HCs). A total 29 studies, comprising 41 task-results, were included systematic review; 32 datasets (n = 1072 disorder; n 1312 HCs) also meta-analyses, conducted each cognitive task separately. Our meta-analyses indicate significant deficits flexibility, attentional set-shifting, bias. Overall, these findings support idea that performance characterize This association may provide possible link between impairments executive functions related action. We discuss practical relevance results, their implications our understanding how they relate neurobiological factors other ‘disorders compulsivity’.
