Background and aims
The Interaction of Person-Affect-Cognition-Execution (I-PACE) model of behavioral addictions is used relatively often as a scientific framework to specify research hypotheses and to interpret empirical findings in behavioral addiction research. There are, however, controversial interpretations in the literature regarding some sp...
Background and aims
There is a lack of research on the impact of acute stress on the interaction of affective and cognitive processes in online compulsive buying-shopping disorder (CBSD). Therefore, this project addressed stress response, cue reactivity, attentional bias, and implicit associations in individuals with online CBSD.
Methods
Women wit...

Habitual responses towards addiction-related cues play a relevant role in the development and maintenance of addictions. Such automatic responses may be more likely under stress, as stress has been shown to induce a shift from goal-directed to habitual behavior. The current study investigated these mechanisms in risky gaming behavior. Individuals w...
Aims: With the increase of online shopping and cashless payment, (online) compulsive buying-shopping disorder (CBSD) has become an increasingly important field of research. However, little attention has been paid to its prevention. Our aim is to identify prevention programs for CBSD respectively to propose prevention approaches for CBSD based on th...
Purpose
Previous research on obesity surgery (OS) showed that patients do not only experience weight loss but also improvements in certain mental health outcomes (e.g., depression) after OS. However, self-harm behaviors might increase after OS. Regarding self-harm, the literature is mostly limited to studies using data from hospital or emergency ro...

Zusammenfassung: Ziel: Durch die COVID-19-Pandemie lässt sich ein Anstieg von psychischen Erkrankungen und des Alkoholkonsums vermuten. Ebenso zeigt sich in der Literatur, dass medizinisches Personal in der Pandemie deutlichen psychischen Belastungen ausgesetzt war. Ziel unserer Untersuchung war es, in der zweiten Lockdownperiode und somit zu einer...

This systematic review focuses on stimuli-specific inhibitory control as measured with variations of Go/No-Go, Stroop, and Stop-Signal tasks including addiction-related cues. We aimed to identify whether individuals with tendencies towards behavioural addictions show stimulus-specific reductions in inhibitory control as assumed by...
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.

Background:
Studies in convenience, non-clinical samples of young adults suggest overlap between online compulsive buying-shopping disorder (OCBSD) and social-networks-use disorder (SNUD). Considering the dearth of research, this study investigated OCBSD and SNUD in clinical samples.
Methods:
Women with either OCBSD (n = 37) or SNUD (n = 41) wer...

Cyberchondria is characterized by excessive online searching for health information and/or digital self‐tracking which is strongly associated with health anxiety, intolerance of uncertainty, anxiety sensitivity, obsessive‐compulsive symptoms, and dysfunctional meta‐cognitive beliefs. To date, it is unclear if individuals with cyberchondria suffer f...
Background
Deficits in inhibitory control seem to promote habit behavior and therefore play an important role in the development and maintenance of addictive diseases. Although several training approaches have been suggested, there is a considerable lack of knowledge about the best way to improve inhibitory control. Based on a literature review reg...
Zusammenfassung: Zielsetzung: Bei Personen vor Adipositaschirurgie wurden die Prävalenzen von Food Addiction (FA), alkoholbezogener Störung, Angst- und depressiven Störungen geschätzt.

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...
Bislang liegen keine allgemeingültigen Vorgaben für die Durchführung der psychosozialen/psychosomatischen Evaluation vor Adipositaschirurgie vor. Die präoperative Untersuchung durch einen in der Adipositasbehandlung erfahrenen Mental Health Professional sollte in jedem Fall ein klinisches Interview, die Diagnostik psychischer Symptome anhand standa...
Bisherige Untersuchungen von Patienten vor Adipositaschirurgie haben gezeigt, dass mehr als die Hälfte im Laufe ihres Lebens bereits direktes oder indirektes selbstschädigendes Verhalten angewendet haben. Allerdings scheint sich die Lebenszeitprävalenz von Selbstschädigung bei Patienten vor Adipositaschirurgie nicht von der bei anderen Personen mit...
Knowledge about atypical eating disorders is still limited although they are often associated with clinically relevant distress, negative effects on physical health and reduction in quality of life. This chapter provides information about atypical anorexia nervosa, substhreshold bulimia nervosa, subthreshold binge eating disorder, purging disorder,...
Es wird davon ausgegangen, dass ein stets verfügbares Überangebot an schmackhaften Nahrungsmitteln maßgeblich zu Kontrollverlust beim Essen, einem daraus resultierenden gesteigerten Nahrungsmittelkonsum und damit auch zur Entstehung von Adipositas beiträgt. Allerdings scheint dies v. a. in Kombination mit einer hohen Impulsivität zutreffend zu sein...

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...

Report Psychologie, 47, 03/2022
With the growth of e-commerce, many consumers have made a shift from in-store to online shopping, and some are at risk for developing online compulsive buying-shopping disorder (CBSD), which can be understood as the virtual equivalent of in-store CBSD or as a disorder due to addictive behaviors under the umbrella of problematic internet usage. Empi...

Pathologisches Kaufen stellt ein schon lange bekanntes und zunehmend erforschtes Phänomen dar, welches erhebliche negative Konsequenzen für die Betroffenen mit sich bringt. Es äußert sich in einer enormen gedanklichen Beschäftigung mit Kaufaspekten, in einem als unwiderstehlich empfundenen Kaufdran...
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...
