Abstract

BackgroundVideo game loot boxes, which can typically be purchased by players or are given as reward, contain random virtual items, or loot, ranging from simple customization options for a player's avatar or character, to game-changing equipment such as weapons and armor. Loot boxes have drawn concern, as purchasing loot boxes might lead to the development of problematic gambling for adolescents. Although parental problem gambling is associated with adolescent problem gambling, no studies have evaluated the prevalence of loot box purchases in adolescents’ parents. ObjectiveThis study investigated the association between loot box purchasing among adolescents and parents, and problem online gaming in population-based samples. MethodsIn total, 1615 adolescent (aged 14 years) gamers from Japan responded to a questionnaire regarding their loot box purchasing and problem online gaming behaviors. Problem online gaming was defined as four or more of the nine addictive behaviors from the Diagnostic and Statistical Manual of Mental Disorders. The adolescents’ primary caregivers were asked about their loot box purchasing. ResultsOf the 1615 participants, 57 (3.5%) reported loot box purchasing. This prevalence did not differ according to primary caregivers’ loot box purchasing, but adolescents who purchased loot boxes were significantly more likely to exhibit problem online gaming (odds ratio 3.75, 95% CI 2.17-6.48). ConclusionsAdolescent loot box purchasing is linked to problem online gaming, but not with parents’ loot box purchasing. Measures to reduce these behaviors should target reducing addictive symptoms in young video gamers.

Abstract

Background: The 22q11.2 deletion syndrome (22q11DS) is characterised by a changing pattern of overlapping intellectual, physical, and mental disabilities along the course of one's life. However, the impact of overlapping disorders (multimorbidity) on educational challenges remains unclear. Method: A survey was conducted with 88 caregivers of individuals with 22q11DS. A quantitative analysis of educational challenges and support needs divided into age groups (7-12, 13-15, 16-18, and 19 years and over) and a qualitative analysis of the free-text items in the questionnaire was conducted. Results: Caregivers were more interested in comprehensive developmental support when their children were younger, and the emphasis shifted to concerns regarding environments that matched individual characteristics at older ages. Furthermore, when there are multiple disabilities or disorders, support is concentrated on the more obvious disabilities, and the lack of support for the less superficially obvious disabilities associated with multiple difficulties, including mental health problems, can be a challenge for people with 22q11DS and their families. Conclusions: This study suggests a need for increased focus on multimorbidity and associated disabilities in school education that are difficult to observe because of their mildness or borderline levels if present alone.

Abstract

Background: Understanding the etiology of psychosis is essential to the development of preventive interventions. The COVID‐19 pandemic provides a rare natural experiment that can expand our understanding of the role of social factors in the trajectories and etiology of psychosis across adolescence, particularly in Tokyo where the prevalence of actual COVID‐19 infection remained low. We hypothesized that the likelihood of self‐reporting psychotic experiences (PEs) would increase following the onset of the COVID‐19 pandemic. Methods: The Tokyo Teen Cohort (TTC) is a prospective cohort study of adolescents in the general population of the Tokyo metropolitan area, followed from age 10 to 16 years. We used multi‐level linear regression models to test the associations between the phase of the COVID‐19 pandemic and self‐reported PEs. Results: Among 1935 adolescents included in the analysis, a rapid increase in PEs occurred at the onset of the COVID‐19 pandemic, following approximately 6 years of steady decline across prior waves. This association was more pronounced for boys compared to girls. This increase became more pronounced as the pandemic moved into later phases, defined based on contemporaneous sociopolitical changes in Tokyo (i.e. changes to school closure, social distancing guidelines, and the state of emergency status). Conclusions: The steady decline in PEs across adolescence was halted and reversed concurrent with the COVID‐19 pandemic onset, despite very low rates of COVID‐19 infection. This implicates COVID‐19 related socioenvironmental factors as contributory etiological factors in the development of PEs in this adolescent cohort. [ABSTRACT FROM AUTHOR]
