The psychological determinants of internet gaming disorder: Vulnerability to stress, psychological well-being, and comorbidity

Introduction A variety of psychological determinants, such as vulnerability to stress, low levels of psychological well-being and several comorbidities, have been hypothesized to play a role in the development, and maintenance of Internet Gaming Disorder (IGD). However, evidence has been insufficient to sustain an overarching model of the causal pathways leading to IGD. Objectives . This study aimed to depict a model of the causal links between vulnerability to stress, psychological well-being, and symptoms of common mental disorders (e.g., depression, generalized anxiety, phobic anxiety, obsessive-compulsive disorder, somatization, and hostility). Methods . A community-based sample of Portuguese gamers (N = 153; Mage = 21.92; 15.29% female) completed measures of IGD (IGDS9-SF), mental health (SCL-90-R), psychological well-being (EBEP), and vulnerability to stress (23QVS). A machine learning algorithm – Greedy Fast Causal Inference – was used to infer a model of the causal pathways linking those psychological determinants to IGD. Results . Hostility and psychological well-being were directly involved with a subgroup of IGD symptoms (i.e., gaming used as escape, tolerance, withdrawal, and loss of control). Stress vulnerability and symptoms of mental disorders were only indirectly implicated in the causal pathways leading to IGD. Conclusions . It is likely that several psychological factors implicated in the causal pathways leading to IGD, have not been yet identified. Future research should directly test specific models of the causal pathways involved in the development and maintenance of IGD symptoms. Disclosure No significant relationships.

Introduction: One of the most recent topics in addictive disorders is videogame-use disorder which is continuously under research, especially in adolescents. The specific structure of digital games (immortality, infinity, etc.) can sensitize adolescents to the development of problematic use. The number of researches about problematic video game use has increased significantly during the last decade. In 2013, this problem was included among "Disorders requiring further research" in DSM-5, and it was also included in ICD-11 as a separate diagnostic category in 2019. Objectives: We review studies investigating the association between the co-occurrence of ADHD and video game use in adolescents. We attempt to summarize new theoretical approaches to video game use disorder and the areas of present research.

Methods:
We conducted a literature search in 4 databases (PubMed, Medline, Google Scholar, Web of Science) using keywords (ADHD, adolescents, video game use disorder, internet addiction, game addiction) over the past 5 years. Exclusion criteria were the following: publication date before 2014, adult population, or comorbidity beside ADHD. Results: The comorbidity of video game use disorder and ADHD was frequent. Primarily cross-sectional studies examined the presence of hyperactivity, attention deficit, and impulsivity symptoms separately. The presence of attention deficit clearly showed an association with the development of video game use disorder. Conclusions: Adolescents diagnosed with ADHD have a greater possibility of developing video game use disorder and/or problematic psychoactive substance users. More attention should be paid to this comorbidity in not only the diagnostic process, but also in the development of prevention programs.
Disclosure: No significant relationships. Keywords: ADHD; adolescents; video game use disorder; addictive disorder

Introduction: There is little prospective data on the risk factors for later suicide in women who experience perinatal mental disorders, particularly beyond one-year postnatal. Objectives: Among a cohort of women who were in contact with a mental healthcare provider during the perinatal period, to: (1) Describe sociodemographic and clinical characteristics of the women who died by suicide (2) Understand when, in relation to childbirth, most suicides tended to occur. Methods: Data-linkage of de-identified service-user electronic healthcare records, national hospital episode statistics and mortality data generated a cohort of women in contact with a mental healthcare service provider in London, UK, perinatally. Using Natural Language Processing and structured field extraction, we identified clinical, socio-demographic characteristics, self-harm exposure, and suicide. Results: Among 5204 women, clinical and demographic characteristics of women who did and did not die by suicide were similar apart from indicators of illness severity including perinatal sedative medication prescription, clinician-rated functional impairment and smoking, which were more common in women who died by suicide. Suicide deaths occurred most frequently in the second year post-delivery. The most common method of suicide ocurring wihtin two years was by violent means, whereas after two years postnatal, the most common method was non-violent. Conclusions: Our findings support the extension of perinatal mental healthcare service provision to two years post-delivery.

Trends in suicides among italian youth aged 10 to 25: A nationwide register study Introduction: Suicide continues to be a significant cause of mortality in most countries worldwide, especially among youth. Documenting current trends and sources of variation in youth suicide rates is critical to inform prevention strategies. Objectives: We aimed to 1. document suicide mortality trends among Italian youth from 1981 to 2016 2. describe age, sex, and urbanization specific suicide rates in this period, and 3. describe suicide methods and their change over time. Methods: We relyed on official mortality data for the period 1981-2016 for adolescents and young adults (ages 10-25 years). We estimated standardized all-cause and suicide mortality rates per 100,000 individuals and used Joinpoint regression analysis to determine annual mortality trends and statistically significant changes in rate trends. Analyses were reported by sex, age group, urbanization level and suicide method.
