AIMS For the first time, the Diagnostic and Statistical Manual for Mental Disorders (DSM-5) introduces non-substance addictions as psychiatric diagnoses. The aims of this paper are to (i) present the main controversies surrounding the decision to include internet gaming disorder, but not internet addiction more globally, as a non-substance addiction in the(More)
OBJECTIVE Our goal was to analyze the retest reliability and validity of the Alcohol Use Disorders Identification Test (AUDIT) in a primary-care setting and recommend a cut-off value for the different alcohol-related diagnoses. METHOD Participants recruited from general practices (GPs) in two northern German cities received the AUDIT, which was embedded(More)
The German federal states initiated the "Pathological Gambling and Epidemiology" (PAGE) program to evaluate the public health relevance of pathological gambling. The aim of PAGE was to estimate the prevalence of pathological gambling and cover the heterogenic presentation in the population with respect to comorbid substance use and mental disorders, risk(More)
BACKGROUND Social capital and a low severity of alcohol-related problems have been focused upon to explain the processes of natural recovery from alcohol dependence. However, studies using control groups have not found significant differences in these variables. Subtypes of natural remission which might account for this inconsistency have only been(More)
BACKGROUND Prevalence studies of Internet addiction in the general population are rare. In addition, a lack of approved criteria hampers estimation of its occurrence. AIMS This study conducted a latent class analysis (LCA) in a large general population sample to estimate prevalence. METHODS A telephone survey was conducted based on a random digit(More)
OBJECTIVES Evidence for brief interventions in general hospital (GH) settings is scarce, probably due to higher rates of dependent drinkers. The present study aims to compare unhealthy drinking patterns in GH patients with the general population (GP). METHODS Sample 1 consisted of 4,075 individuals randomly drawn from registration office files,(More)
BACKGROUND Research on natural recovery from alcohol dependence has focused mainly on triggering mechanisms of the remission process. Only a few studies have considered maintenance factors of natural recovery. METHODS In the present study, 93 natural remitters and 42 self-help group participants were compared. Both groups remitted from alcohol dependence(More)
OBJECTIVE Screening for problem drinking has not yet become standard practice in primary health care settings, and lack of time is an important barrier for general practicioners to intervene. Very brief screening instruments might help to implement screening into the daily routine in primary health care. The present study describes the development and(More)
AIMS Dependence on or problematic use of prescription drugs (PD) is estimated to be between 1 and 2% in the general population. In contrast, the proportion of substance-specific treatment in PD use disorders at 0.5% is comparatively low. With an estimated prevalence of 4.7%, PD-specific disorders are widespread in general hospitals compared to the general(More)
BACKGROUND Brief interventions (BIs) are effective methods to reduce problematic drinking. It is not known, if the effectiveness of BI differs between patients with or without comorbid depression or anxiety disorders. METHODS In a randomized controlled BI study with two intervention groups and one control condition, data were collected from 408 general(More)
