The Self-regulatory Executive Function model elucidates how metacognitions link to the development and maintenance of gambling disorder, however whether, and how, metacognitions explain responsible gambling remains unknown. This study is the first to address this knowledge gap by: (a) examining whether both generic and gambling-specific metacognitions explain variances in responsible gambling; and (b) testing the mediating role of depression between generic/gambling-specific metacognitions and responsible gambling. A two-stage cluster random sampling method was used to obtain a probability sample of 837 Chinese adult gamblers (48.

Responsible gambling (RG) is a practical approach to contain potential gambling-associated harms to an acceptable level. However, few studies have proposed a theoretical framework to account for significant individual differences in RG adherence, which hinders an effective RG promotion in public. To address this missing link, the current study aims to identify psychological need factors associated with adherence to RG practices.

Background: This longitudinal study investigated the temporal stability of social axioms, which are generalised social beliefs, and tested their prospective effects on individuals' flourishing, among students, as well as the extent to which they can be potentially mediated by perceived sense of belonging at school.

Methods: Participants were 195 Chinese university students, who voluntarily completed a questionnaire measuring social axioms (at baseline, 1-year follow-up, and 2-year follow-up studies), school belonging (at 1-year follow-up study), and flourishing (at baseline and 2-year follow-up studies).

Results: Results showed supportive evidence for five types of social axioms being generally stable across these time intervals.

Despite the increasing research attention being paid to gaming disorder globally, a screening tool developed specifically for the Chinese population is still lacking. This study aims to address this gap by constructing a screening tool to assess Internet gaming disorder (IGD) symptomology, defined by the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), among Chinese gamers. Based on expert interviews and consultations, a focus group of gamers, a background literature review, and the IGD criteria proposed by the DSM-5, we developed the Chinese Internet Gaming Disorder Checklist (C-IGDC).

Objective: Previous genome-wide association studies (GWAS), which were mainly based on single-variant analysis, have identified many systemic lupus erythematosus (SLE) susceptibility loci. However, the genetic architecture of this complex disease is far from being understood. The aim of this study was to investigate whether using a gene-based analysis may help to identify novel loci, by considering global evidence of association from a gene or a genomic region rather than focusing on evidence for individual variants.
