An-Pyng Sun (Social Work), Chih-Hsiang Ho (Mathematical Sciences), Daria J. Kuss (Nottingham Trent University), and Chad L. Cross (Epidemiology and Biostatistics) recently published an article, “,” in the journal Addictive Behaviors Reports. As gaming disorder (GD) is a new phenomenon, its diagnosis requires research data to support its validity, including data on temporal stability. Sun et al.’s meta-analysis indicates: around 40% of GD-positive gamers at baseline retained that diagnosis at follow-up; the severity of problematic gaming symptoms at baseline predicts their severity at follow-up; many factors may affect GD's temporal stability, including severity, clinical vs. nonclinical populations, and patients' developmental stage. Although GD's categorical stability is lower than some severe mental disorders, it is comparable to personality disorder or gambling disorder.
