Background and aims
Research on the development of gaming disorder assumes that the quality of reinforcement learning as well as the content of use expectancies are initially rewarding in the early stages of the addictive behavior and becomes steadily more compensatory in the later stages. This assumed transition could be reflected in gaming-relate...
Purpose of review
This narrative review provides a detailed look at impulsivity in the context of gaming disorder. Summarizing empirical findings, we aim to identify whether gaming disorder is associated with specific facets of impulsivity, namely motor, attentional, and decisional impulsivity, assessed by self-report and behavioral measures. Where...
The Journal of Behavioral Addictions featured a debate on the topic of "behavioral addictions in ICD-11" in 2022. Three main debate papers were published and a total of eleven commentaries. One main topic of considerations in the three debate papers and in the majority of commentaries was compulsive sexual behavior disorder. The debate was balanced...
Social networks are frequently used to distract, procrastinate, or cope with stress. We aimed to investigate how (problematic) social-networks use affect stress perception in interaction with different stress recovery conditions. A total of 104 participants were randomly assigned to one of four groups. Three groups underwent a stress induction with...
Implicit cognitions may be involved in the development and maintenance of specific Internet use disorders such as problematic social network use (PSNU). In more detail, implicit attitude, attentional biases, approach and avoidance tendencies as well as semantic memory associations are considered relevant in the context of PSNU. This viewpoint artic...
Background and aims:
Compulsive buying-shopping disorder (CBSD) is mentioned as an example of other specified impulse control disorders in the ICD-11 coding tool, highlighting its clinical relevance and need for treatment. The aim of the present work was to provide a systematic update on treatment studies for CBSD, with a particular focus on onlin...
Background:
Gaming disorder (GD) is a disorder due to addictive behaviors (ICD-11). Cue-reactivity and craving are relevant mechanisms in the development and maintenance of addictive behaviors. When confronted with cues showing in-game content (proximal cues) individuals with higher symptom severity show increased cue-reactivity. Based on conditio...
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,...
Introduction:
Craving, involving intense and urgent desires to engage in specific behaviours, is a feature of addictions. Multiple studies implicate regions of salience/limbic networks and basal ganglia, fronto-parietal, medial frontal regions in craving in addictions. However, prior studies have not identified common neural networks that reliably...
Introduction
Although the majority of internet users enjoy the internet as a recreational activity, some individuals report problematic internet use behaviors causing negative psychosocial consequences. Therefore, it is important to have precise and valid diagnostic criteria to ensure suitable treatment for those affected and avoid over-pathologiza...
Introduction
Internet use disorder is a disorder of the digital age and presents a growing problem worldwide . It appears that due to structural and personal barriers, many persons affected (PA) and Concerned Significant Others (CSO) do not reach the health care system so far and thus a chronification of the pathology can proceed.

A teleme...
Purpose of Review
A core symptom of problematic pornography use (PPU) is the repeated failure to control sexual impulses resulting in pornography use; however, the field of self-regulation research has rarely been applied to PPU.
Recent Findings
Various goals can underly the use of online pornography. These goals can conflict with other self-regul...
Self-disclosures on online social networks have received increased attention in the last two decades. Researchers from different disciplines investigated manifold influencing variables, and studies applied different theories to explain why many users share very sensitive and personal information despite potential risks and negative consequences, wh...
Aims: The problematic use of social networks is discussed as a further specific type of Internet-use disorders. Our project aims to clarify whether social-networks-use disorder (SNUD) is marked by characteristics of addictive behaviors by tracking behavior and investigating the relevance of 1) implicit cognitions, 2) the experiences of gratificatio...
Although consequences of sharing personal information can be negative and severe (e.g., identity theft), individuals still engage in extensive self-disclosures on social networks. One commonly applied explanatory approach is the privacy calculus. Following this, self-disclosures can be conceptualized as rational choices resulting from a weighing of...
Using digital media has become the most popular leisure activity for children and adolescents. The effects of digital media use on the developing brain and cognitive processes of children are subject to debate. Here, we examine the effect of digital media use on attention subdomains in children aged 6 to 10 years. In total, 77 children participated...
Background and aims:
Compulsive sexual behavior disorder (CSBD) which includes problematic pornography use (PPU) is a clinically relevant syndrome that has been included in the ICD-11 as impulse control disorder. The number of studies on treatments in CSBD and PPU increased in the last years. The current preregistered systematic review aimed for i...
Online self-disclosure is perhaps one of the last decade’s most studied communication processes, thanks to the introduction of Online Social Networks (OSNs) like Facebook. Self-disclosure research has contributed significantly to the design of preventative nudges seeking to support and guide users when revealing private information in OSNs. Still,...

Global concern about problematic usage of the internet (PUI), and its public health and societal costs, continues to grow, sharpened in focus under the privations of the COVID-19 pandemic. This narrative review reports the expert opinions of members of the largest international network of researchers on PUI in the framework of the European Cooperat...
The paper by Sassover and Weinstein (2022) contributes to a timely and complex debate related to the classification of Compulsive Sexual Behavior Disorder (CSBD). The recent inclusion of CSBD as an impulse control disorder in the ICD-11 has generated debate since a competitive view is that CSBD should rather be classified as an addictive disorder....
Purpose of Review
Problematic pornography use (PPU) describes a pattern of behavior characterized by excessive time spent using or thinking about pornography and continued use despite negative consequences. To help advance the understanding of transdiagnostic underlying psychological and neurobiological mechanisms in PPU, we aim to review existing...
Background:
The risk for behavioral addictions is rising among women within the general population and in clinical settings. However, few studies have assessed treatment effectiveness in females. The aim of this work was to explore latent empirical classes of women with gambling disorder (GD) and buying/shopping disorder (BSD) based on the treatme...
Background
Beyond gaming disorder and gambling disorder, pornography-use disorder, buying-shopping disorder, and social-networks-use disorders are discussed as further disorders due to addictive behaviors. For addictive behaviors, it is assumed that the experience of gratification and the experience of compensation due to the specific behavior repr...
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 fo...
Motherhood has been proposed as an internal facilitating factor for the recovery of women with mental disorders. However, at the same time, there are significant barriers that may be interfering with the access and adherence to treatment for these women. The present longitudinal study aimed to deepen the sociodemographic and clinical profile of wom...
Problematic usage of the Internet (PUI) is an umbrella term covering a range of problematic behaviors including online addictive behaviors, such as gaming disorder, pornography-use disorder, buying–shopping disorder, and problematic social networks use. Theoretical models of PUI can not only inspire research on psychological and neurobiological mec...
Traditional mindfulness interventions have been frequently reported to be effective in improving cognitive functions. In recent years, however, traditional programs are increasingly replaced by technology-enabled mindfulness interventions. The aim of the present systematic review (PROSPERO ID: CRD42021289480) was to evaluate the research evidence o...
Background and aims
With the inclusion of gaming disorder in the ICD-11, diagnostic criteria were introduced for this relatively new disorder. These criteria may also be applied to other potential specific Internet-use disorders, which may be classified in ICD-11 as other disorders due to addictive behaviors, such as online buying-shopping disorder...
Background:
Compulsive buying-shopping disorder (CBSD) is associated with high materialistic values endorsement and excessive purchasing of consumer goods. A subgroup of individuals with CBSD engage in socially unacceptable behaviors to continue shopping despite negative consequences. This investigation aimed at exploring possible links between eg...
Sexual intercourse initiated through a sex dating online platform, sexually suggestive interpersonal communication via a messaging app, or flirtation with a voice assistant are examples of sexual interaction in digital contexts. In all of these cases the interaction is linked to both sexual arousal and digital technology. The digitalization of huma...

The uncontrolled use of specific Internet applications is increasingly recognized as a mental health issue. Gaming disorder, which is one subtype of specific Internet-use disorders (sIUDs), has been included in the ICD-11 as disorder due to addictive behaviors. Addictive disorders are assumed to be accompanied by cognitive deficits as indicated by...
The term “Internet-use disorders” covers a range of different conditions including gaming and gambling disorder and problematic use of pornography, buying-shopping, and social networks. These conditions are often viewed and treated as addictive disorders. Although Internet-use disorders have been recognized as an internationally relevant public hea...
Purpose of Review
Problematic online buying-shopping became a recent research topic, and the question arises as to whether it would be useful to differentiate between a “predominantly online” and a “predominantly offline” compulsive buying-shopping disorder (CBSD) subtype by analogy with gaming disorder and gambling disorder in the ICD-11. This nar...
Zusammenfassung. Zielsetzung: Der Beitrag stellt die deutsche Übersetzung der Diagnosekriterien für die Kauf-Shopping-Störung vor, die im Rahmen einer internationalen Delphi-Studie entwickelt wurden.

Background
Internet Use Disorders (IUD) cover a range of online-related behavioral addictions, which are acknowledged and strengthened by the inclusion of (online) gaming disorder in the ICD-11 by the World Health Organization. Internet-based telemedicine interventions offer the possibility to reach out for individuals with IUD where the disorder e...
Based on its prevalence, there is an urgent need to better understand the mechanisms, opportunities and risks of sexual interaction in digital contexts (SIDC) that are related with sexual arousal. While there is a growing body of literature on SIDC, there is also a lack of conceptual clarity and classification. Therefore, based on a conceptual anal...

Background and aims
An increasing number of people experience negative consequences from the excessive use of different Internet applications or sites (e.g., Instagram, League of Legends, YouTube). These consequences have been referred to as specific Internet Use Disorders (IUDs). The present study aims to examine the Fear of Missing Out (FoMO) on...
The increasing relevance to adapt quickly to changes in the environment is contrasted by an inverted U-shaped curve of task-switching abilities over the lifespan. While previous studies most commonly focused on switching between rules, modalities, and attributes, the process of switching between different attentional demands is somehow neglected. T...
Purpose of Review
There are ongoing debates about specific features of compulsive sexual behavior disorder (CSBD) relating to classification and diagnoses. We aim to address current discussions relating to potential subtypes of CSBD, the aspect of compulsivity in CSBD, and the aspect of moral incongruence and CSBD.
Recent Findings
CSBD includes mu...
In the eleventh International Classification of Diseases (ICD‐11) of the World Health Organization, gambling disorder and gaming disorder are included in the category ‘disorders due to addictive behaviours’, which can be specified further as occurring either predominantly offline or predominantly online. Other specific problematic behaviours may be...
Aims: In this narrative position paper, we will summarize some examples of theoretical models of behavioral addictions. We will then make some suggestions for how theoretical models may inspire both research and clinical practice in the context of behavioral addictions. Results: Current theoretical models typically distinguish between general and s...

Religious and ethical beliefs and moral values may influence sexuality including perception of pornography and its frequency of use, and engagement in sexual behaviors including pornography viewing may impact thes...
Background and aims:
Social-networks-use disorder is discussed as a potential further type of disorders due to addictive behaviors. Theoretical models assume cue-induced craving and disadvantageous decision making to be relevant mechanisms. This study investigates if the presentation of social-networks-related cues interferes with decision making...
Background and Aims
Buying-shopping disorder (BSD) is a clinical condition in which individuals lose control over their buying behaviour and continue buying despite negative consequences such as indebtedness, loss of family and friends. BSD has been considered a behavioural addiction and first studies provide evidence for cue-reactivity and craving...
In several studies, individuals who reported to frequently multitask with different media displayed reduced cognitive performance, for example in fluid intelligence and executive functioning. These cognitive functions are relevant for making advantageous decisions under both objective risk (requiring reflection and strategical planning) and ambiguo...
Background and aims:
Consensus in acknowledging compulsive buying-shopping disorder (CBSD) as a distinct diagnosis has been lacking. Before research in this area can be advanced, it is necessary to establish diagnostic criteria in order to facilitate field trials.
Methods:
The study consisted of the following phases: (1) operationalization of a...
Problematic usage of the internet (PUI) describes maladaptive use of online resources and is recognized as a growing worldwide issue. Here, we refined the Internet Addiction Test (IAT) for use as a screening tool to measure generalized internet use problems in normative samples. Analysis of response data with parametric unidimensional item response...
Driving in a simulator might induce stress because of the confrontation with new environments, dealing with new technologies, and experience with symptoms of simulator sickness, which, in turn, may influence individuals’ driving performance. The present study aims to provide a better understanding of the association between simulated environments a...
The occurrence of the COVID-19-virus led to drastic short-term measures to reduce its spread and influence. Regulations such as “physical distancing,” mentioned as “social distancing,” and the closure of public facilities during the lockdown could be perceived as burdensome especially by individuals who feel a strong need for social exchange and be...
Introduction
Desire thinking is defined as a voluntary cognitive activity aimed at imaginatively and verbally elaborating a future scenario of performing a desired behavior. Although not problematic per se, desire thinking can become dysfunctional if it is used to regulate negative mood states and due to its ability to induce craving. This study te...
Introduction:
While identity problems and materialistic value endorsement have been described as predisposing factors for buying-shopping disorder (BSD) in the literature, little empirical data are available on the role of socially undesirable personality features that may contribute to financial misconduct and manipulative interpersonal behaviors...
Background
The tendency to strive for immediate gratification by neglecting potential negative long-term outcomes characterizes addictive behaviors, such as substance use or gaming disorder. Problematic social-network use is currently discussed as another potential addictive behavior, which is considered to result from an imbalance between affectiv...
This special issue addresses the affective and cognitive processes and their interactions potentially reflecting mechanisms underlying the development, maintenance of, or recovery from behavioral addictions. Various specific types of behavioral addictions will be considered, including those already in ICD-11 (gambling disorder, gaming disorder), bu...
Background
Theoretical models summarize the mechanisms that are potentially involved in the development and maintenance of a psychological disorder. Regarding behavioral addictions, several models exist that are mainly based on theories explaining substance use disorders.Objective
