To gamble or not to gamble: at risk for craving and relapse--learned motivated attention in pathological gambling.

In recent research similarities between pathological gambling and drug addiction have been identified, suggesting excessive gambling to constitute an addiction. So far, we have insufficient knowledge concerning the psychophysiological mechanisms underlying this kind of non-substance-related addiction. The objective of the study was to investigate emotional processing of gambling-relevant and -irrelevant stimuli in pathological gamblers and non-gambling controls using an EEG cue-reactivity paradigm.

Diagnostic instruments for behavioural addiction: an overview.

In non-substance-related addiction, the so-called behavioural addiction, no external psychotropic substances are consumed. The psychotropic effect consists of the body's own biochemical processes induced only by excessive activities. Until recently, knowledge was limited with respect to clinically relevant excessive reward-seeking behaviour, such as pathological gambling, excessive shopping and working which meet diagnostic criteria of dependent behaviour.

[Excessive computer usage in adolescents--results of a psychometric evaluation].

Excessive computer and video game playing among children is being critically discussed from a pedagogic and public health point of view. To date, no reliable data for this phenomenon in Germany exists. In the present study, the excessive usage of computer and video games is seen as a rewarding behavior which can, due to learning mechanisms, become a prominent and inadequate strategy for children to cope with negative emotions like frustration, uneasiness and fears.

Immigration-associated variables and substance dependence.

Objective: Drug-dependent patients show increased negative mood states such as anxiety and depression that interact with drug craving and quality of life. In this study, we compared immigrants with and without drug dependence and assessed whether drug dependence and social status after immigration contributed independently to negative mood states, stress-coping strategies and satisfaction with life in Germany.

Method: Immigrants (N = 80) who had emigrated from the former Soviet Union to Germany were participants in the study.

[Excessive compulsive buying or "behavioral addiction"? A case study].

Compulsive buying is characterized by repetitive compulsive and excessive misappropriated buying. Labels for this pathological behavior vary and its classification is uncertain. To date, there is no consistent concept for diagnosis and treatment.
