Prevalence of Problem Gambling: A Meta-analysis of Recent Empirical Research (2016-2022).

Gambling is widely considered a socially acceptable form of recreation. However, for a small minority of individuals, it can become both addictive and problematic with severe adverse consequences. The aim of this systematic review and meta-analysis is to provide an overview of prevalence studies published between 2016 and the first quarter of 2022 and an updated estimate of problem gambling in the general adult population. A systematic review and a meta-analysis were carried out using academic databases, Internet, and governmental websites. Following this search and utilizing exclusion criteria, 23 studies on adult gambling prevalence were identified, distinguishing between moderate risk/at risk gambling and problem/pathological gambling. This study found a prevalence of moderate risk/at risk gambling to be 2.43% and of problem/pathological gambling to be 1.29% in the adult population. As difficult as it may be to compare studies due to different methodological procedures, cutoffs, and time frames, the present meta-analysis highlights the variations of prevalence across different countries, giving due consideration to the differences between levels of risk and severity. This work intends to provide a starting point for policymakers and academics to fill the gaps on gambling research-more specifically in some countries where the lack of research in this field is evident-and to study the effectiveness of policies implemented to mitigate gambling harm.

National Helpline for Problem Gambling: A Profile of Its Users' Characteristics.

Gambling has seen a significant increase in Italy in the last 10 years and has rapidly become a public health issue, and for these reasons the first National Helpline for Problem Gambling (GR-Helpline) has been established. The aims of this study are to describe the GR-Helpline users' characteristics and to compare the prevalence rates of the users with those of moderate-risk/problematic gamblers obtained from the national survey (IPSAD 2010-2011). Statistical analysis was performed on data obtained from the counselling sessions (phone/e-mail/chat) carried out on 5,805 users (57.5% gamblers; 42.5% families/friends). This confirms that the problems related to gambling concern not only the gamblers but also their families and friends. Significant differences were found between gamblers and families/friends involving gender (74% of gamblers were male; 76.9% of families/friends were female), as well as age-classes and geographical area. Female gamblers had a higher mean age (47.3 versus 40.2 years) and preferred nonstrategy-based games. Prevalence rates of GR-Helpline users and of moderate risk/problematic gamblers were correlated (Rho = 0.58; p = 0.0113). The results highlight the fact that remote access to counselling can be an effective means of promoting treatment for problem gamblers who do not otherwise appeal directly for services.

Language plasticity revealed by electroencephalogram mapping.

Reasoning is the result of the computations made by intelligent systems, for instance those in the brain. It is not an abstract concept because calculations performed by computations are very concrete transactions among the different central processing unit components. Entropy measurements are proposed here to disclose the plasticity of the cerebral processing associated with language comprehension in video game playing. It is also assumed that entropy may be evaluated from the correlation coefficients obtained for the game event-related activity calculated for the different electroencephalogram derivations in the 10/20 system. The brain mapping derived from these entropy measurements clearly demonstrates the reallocation of speech functions to right brain areas when the classic left language circuits are damaged during prenatal life.
