The Importance of Leisure Activities for Suicidality in Adolescents and Young Adults Leisure time is important for the development of adolescents. It influences adolescents' psychological well-being and psychosocial development. It may also have a protective effect on suicidality. This study investigates how adolescents' leisure time is related to suicidality, distinguishing between general aspects and various specific leisure time activities. Data from adolescents in counseling (n = 25) and the general population (n = 57) were analyzed. Adolescents who spend most of their leisure time alone are more suicidal than adolescents who spend their leisure time with others. General aspects of leisure activities were related to suicidality; among specific activities, only sports activities were found to be significant.The strongest association with suicidality was shared activities with others. Based on these results, it can be shown that leisure time activities could be effective as a preventive measure. In particular, social activities in leisure time should be encouraged.

Demographic, lifestyle, social, and psychological factors associated with worry-related sleep problems among school-going adolescents in Timor-Leste.

OBJECTIVE: Adolescent sleep problems are a worldwide public health issue. The present study examines factors associated with worry-related sleep problems among school-going adolescents. The country of interest is Timor-Leste, a low-income country, where studies pertaining to adolescent sleep problems are lacking. DESIGN AND MEASURES: Data were analysed from the Global School-Based Student Health Survey Timor-Leste (n = 3455). An ordered probit model was used to assess the effects of demographic, lifestyle, social, and psychological factors on different levels of worry-related sleep problems (i.e., no, mild and severe sleep problems). RESULTS: School-going adolescents were more likely to face mild or severe worry-related sleep problems if they were older, passive smokers, alcohol drinkers and moderately active. School-going adolescents who sometimes or always went hungry were more likely to experience worry-related sleep problems than those who did not. Involvement in physical fights, being bullied, and loneliness were positively associated with the probability of having modest or severe worry-related sleep problems. CONCLUSION: Age, exposure to second-hand smoke, alcohol consumption, physical activity, going hungry, physical fights, being bullied and loneliness are the important determining factors of adolescent worry-related sleep problems. Policymakers should pay special attention to these factors when formulating intervention measures.

How adolescents lose control over social networks: A process-based approach to problematic social network use.

Social networks (SNs) are immensely popular, especially among teenagers, yet our understanding of problematic SNs remains limited. Understanding motivations and patterns of use is crucial given the current prevalence of problematic SNs use. Perarles et al. (2020) distinguish two behavioral control modes: Model-Free Control, where actions are characterized by actions driven by immediate gratification without reflective consideration for long-term consequences, and Model-Based Control, enabling planned and goal-directed actions. Both control modes can lead to problematic social network use. This study aims to delve into problematic SNs use and the underlying motives behind adolescents' participation in SNs, drawing upon the theoretical proposal by Perales et al. (2020). We conducted four focus groups with adolescents aged 13-17 (50 % female; Mage = 14.5, SD = 1.75), comprising two public school and two Catholic private school groups. Thematic analysis using Atlas.ti software revealed three themes. The first uncovers characteristics of problematic SNs use, including withdrawal, increased usage time, impaired control, behavioral salience and attentional capture and cognitive hijacking. The second spotlights motives, emphasizing emotional regulation, finding out what is going on, and social interaction. The third theme explores consequences such as compromised academic performance and physical harm. In conclusion, addressing both motives and problematic behaviors present a more effective approach to confronting SNs use challenges and fostering healthier online experiences for adolescents.

Patterns in Tobacco, E-Cigarette, and Cannabis Advertising Exposure Among California Adolescents and Associations With Future Use Expectations.

BACKGROUND: Exposure to tobacco, e-cigarette, or cannabis marketing is associated with adolescent use. Few studies have examined advertising exposure prevalence and patterns across these products concurrently. METHODS: This study assessed past 30-day recalled exposure to promotional messages about tobacco, e-cigarettes ("vapes" on the survey), and cannabis ("marijuana") from various sources among California adolescents (ages 12-17) in the 2022 Teens, Nicotine, and Tobacco Online Survey (N = 2530). Principal components analysis (PCA) was conducted to examine the underlying structure and patterns in advertising exposure sources. Multivariable logistic regression was used to evaluate associations between any advertising exposure and future use expectations (a susceptibility measure) in one year and at age 25 among current never-users. RESULTS: Overall, 65.9% of participants recently noticed at least one tobacco (52.5%), vape (51.5%), or marijuana (45.6%) advertisement. Gas stations or convenience stores were the most common source for tobacco or vape ads; billboards were for marijuana ads. In PCA, advertising exposure patterns correlated with advertising source, not the type of product. Exposures from tobacco-specific sources and nearer point of sale were associated with current use, older age, LGBTQ + identity, and sensation seeking. Among never-users, advertising exposure was associated with one-year and age-25 use expectations for cigarettes (one-year expectations adjusted odds ratio: 1.7; 95% CI: 1.1, 2.5), vapes (2.3; 1.5, 3.5), and marijuana (2.1; 1.5, 3.0). CONCLUSION: California adolescents' exposure to tobacco, e-cigarette, and cannabis marketing is common, follows similar patterns, and is associated with use susceptibility. Comprehensive restrictions on marketing accessible to adolescents could help prevent youth use.

Investigating the effects of postural habits and awareness on early adolescent's internet addiction levels.

OBJECTIVES: Early adolescence is a period of growth and development determined by the onset of puberty, during which important changes in psychological development and social roles occur. Excessive use of the internet, especially in adolescents in this period, causes health problems such as postural disorders, vision problems, sedentary life, and unbalanced nutrition. When the studies are analyzed, it is observed that postural disorders are observed in children and adolescents. This study was planned to investigate the effect of postural habits and awareness on the level of internet addiction in early adolescents. METHODS: Physical characteristics of the participants (age, height, weight, gender, body mass index) were recorded. Duration and purpose of internet use and internet addiction were determined with the Young Internet Addiction Test-Short Form, body composition sensitivity level with the Body Awareness Questionnaire, and postural awareness with the Postural Habit and Awareness Scale. RESULTS: There was a significant positive correlation between internet addiction and duration of internet use (r=0.466) (p=0.000). In addition, there was no relationship between internet usage time and body awareness (r=-0.117) (p=0.084) and postural awareness and habit (r=-0.017) (p=0.798). When internet addiction was compared with body awareness, a significant relationship was found in the opposite direction (r=-0.145) (p=0.031). When internet addiction was compared with postural awareness and habit, a positive relationship was found (r=0.190) (p=0.005). CONCLUSIONS: Our study showed that internet addiction negatively affects body awareness, and does not affect postural habits, but positively affects postural awareness.

Exploring the determinants of internet addiction among Peri-urban adolescents (aged 13-18) in Delhi-NCR, India: an ordered logit model analysis.

OBJECTIVES: In recent years, there has been phenomenal growth in internet usage worldwide, with a substantial proportion of children and adolescents actively engaging with online platforms. While the internet presents numerous opportunities for children and adolescents, the lack of digital literacy and adequate online safety measures exposes them to various cybercrimes, including cyberbullying, cyberstalking, identity theft, and sexual predation. Moreover, there is growing concern regarding internet addiction among this population. METHODS: To investigate the determinants of internet addiction among adolescents, we conducted a cross-sectional study in peri-urban Delhi-NCR, India. We used a self-administered questionnaire to gather information on internet usage, and 630 adolescents aged 13-18 participated in the study, also completing an Internet Addiction Test. RESULTS: The findings indicate that 415 adolescents (65.9 %) exhibited no signs of internet addiction, suggesting a healthy relationship with the internet. However, 215 adolescents (33.1 %) displayed symptoms of internet addiction. Among those exhibiting internet addictions, 159 (74.0 %) were classified as mild internet addicts, indicating moderate levels of internet usage. Furthermore, 56 (26.0 %) adolescents were classified as moderate internet addicts, reflecting a higher level of internet addiction. CONCLUSIONS: Our study highlights the significant influence of various factors, including family dynamics, environmental factors, and personal experiences, on internet addiction among adolescents. Based on these findings, we propose implementing measures at different levels to foster responsible internet use among adolescents, thereby substantially reducing internet addiction.

Hope in adolescence and subsequent health and well-being in adulthood: An outcome-wide longitudinal study.

BACKGROUND: A sense of hopelessness is rising at alarming levels among adolescents in the United States. There is urgent need to understand the potential implications of being hopeful on adolescents' future health and wellbeing. METHODS: This study utilized data from the National Longitudinal Study of Adolescent to Adult Health (N = 11,038, mean age at baseline = 15 years) to prospectively examine the relationship between baseline hope and a wide range of outcomes 12 years later. Thirty-eight outcomes were examined in the domains of physical health, health behavior, mental health, psychological well-being, social factors, and civic and prosocial behavior. Regression models were used to regress each outcome on baseline hope separately. Models controlled for a wide range of factors as well as prior values of the exposure (hope) and outcomes. RESULTS: Having hope for the future in adolescence was associated with improvements in 11 subsequent outcomes after Bonferonni correction, including higher cognition and self-rated health, less physical inactivity, fewer depressive symptoms, lower perceived stress, and improvement on a number of psychological and social factors including greater happiness, more satisfaction with parenting, and increased voting and volunteering in adulthood. There were also a number of associations that were close to the null, which are equally important to explore and understand. IMPLICATIONS: The results of the study may have important implications for hope-based efforts and programs aimed at improving the lives of young people and promoting their current and future well-being.

Adolescents with emotional and behavioural problems are at higher risk to become excessive or addicted Internet users: is this association moderated by gender?

BACKGROUND: The Internet offers many opportunities for adolescents to facilitate their lives. However, its everyday use may lead to excessive behaviour, including addiction. Our aim was to assess the association between emotional and behavioural problems (EBP) and level of internet use, and whether gender moderates this association. METHODS: We used data from a representative sample of 5,433 Slovak adolescents (mean age: 13.51, 48.8% boys) from the Health Behaviour in School-aged Children-study conducted in 2018, collected through online self-report questionnaires. EBP was measured by the Strengths and Difficulties Questionnaire and excessive internet use (EIU) and internet addiction (IA) by the Excessive internet use scale. We analysed using multinomial logistic regression. RESULTS: More than 25% of the adolescents reported EIU; almost 4% reported being addicted to Internet. EIU was more prevalent in girls, but IA was more prevalent in boys. Adolescents with borderline or increased levels of EBP were more likely to report EIU (odds ratio, OR/95% confidence interval, CI: 1.85/1.60-2.14; 3.16/2.67-3.75, respectively) and IA (OR/95% CI: 2.23/1.57-3.18; 4.89/3.41-7.03, respectively). Adjustment for gender, age or perceived family wealth hardly changed the findings. Moreover, gender did not modify the associations between EBP with EIU. CONCLUSION: Adolescents with higher levels of EBP are more likely to become excessive Internet users or Internet addicts. This shows a need of early identification of adolescents with EBP as they seem to be relatively vulnerable to develop EIU or IA.

Social Media Use and Alcohol Sipping in Early Adolescents: A Prospective Cohort Study.

BACKGROUND: Social media can influence alcohol initiation behaviors such as sipping, which can lead to future adverse alcohol-related outcomes. Few studies have examined the role of problematic social media use, characterized by addiction, mood modification, tolerance, withdrawal, conflict, and relapse, especially in early adolescence. OBJECTIVE: To examine the prospective association between social media use and sipping alcohol in a nationwide sample of early adolescents, and the extent to which problematic social media use mediates the association. METHODS: We analyzed prospective data from the Adolescent Brain Cognitive Development Study (N = 7514; ages 9-10 years at baseline; 2016-2018) to estimate associations between social media time (Year 1) and alcohol sipping (Year 3) using modified Poisson regression, adjusting for confounders and testing problematic social media use (Year 2) as a mediator. RESULTS: Social media time (Year 1) was prospectively associated with 1.31 (95% confidence interval 1.20-1.43) times higher risk of new-onset sipping (Year 3). The association between social media time and new-onset alcohol sipping was partially mediated by problematic social media use at Year 2 (25.0% reduction in the association between the former two factors after adding problematic social media use, p = 0.002). CONCLUSIONS: Time spent on social media was associated with a higher risk of alcohol sipping in a diverse national sample of early adolescents, and the association was partially mediated by problematic social media use. Media literacy education and family media use plans could advise early adolescents about exposure to alcohol content on social media and warning signs for problematic use.

Prevalence and factors associated with risky sexual behavior among Brazilian school adolescents. / Prevalência e fatores associados ao comportamento sexual de risco de adolescentes escolares brasileiros.

This article evaluated the prevalence and factors associated with risky sexual behavior (RSB) among Brazilian school adolescents. This is a cross-sectional study with data collected from the National Survey of School Health, 2019 edition, with a representative sample of 7th grade of elementary school to 3rd year of high school Brazilian school adolescents. This work evaluated sociodemographic, behavioral, sexual and reproductive health, mental health, sociability characteristics, medical advice received at school, and body image. RSB was characterized as the non-use of a condom during sexual intercourse. The data were analyzed using hierarchical Poisson regression modeling. The prevalence of RSB was of 40.3%, with the lowest proportion appearing in the North region (37.4%). The highest prevalence of RSB was found among female adolescents, whose first sexual intercourse occurred at 13 years of age or under, who were victims of sexual violence, who practiced bullying, and who used illicit drugs, cigarettes, and alcohol. Those who used a condom during their first sexual intercourse showed the lowest prevalence of RSB. The high prevalence of RSB among Brazilian school adolescents, together with the knowledge of the associated factors, serves to define strategies to favor improvements in the sexual and reproductive health of these young people.

O artigo avaliou a prevalência e fatores associados ao comportamento sexual de risco (CSR) de adolescentes escolares do Brasil. Trata-se de estudo transversal com dados da Pesquisa Nacional de Saúde do Escolar, 2019, com amostra representativa de adolescentes escolares brasileiros do 9º ano do ensino fundamental. Foram avaliadas características sociodemográficas, comportamentais, de saúde sexual e reprodutiva, de saúde mental e de sociabilidade, orientações recebidas na escola e autoimagem corporal. Caracterizou-se o CSR como o não uso de preservativo na última relação sexual. Os dados foram analisados por modelo hierarquizado com regressão robusta de Poisson. A prevalência de CSR foi de 40,3%, com menor proporção na região Norte (37,4%). Houve maior prevalência do CSR entre adolescentes do sexo feminino, cuja primeira relação sexual ocorreu com 13 anos ou menos, que foram vítimas de violência sexual, que praticaram bullying e que usaram drogas ilícitas, cigarro e álcool. Aqueles que usaram preservativo na primeira relação sexual apresentaram menor prevalência de CSR. A alta prevalência de CSR entre adolescentes escolares no Brasil, aliada ao conhecimento dos fatores associados, deve propiciar o estabelecimento de estratégias para favorecer a melhoria na saúde sexual e reprodutiva desses jovens.

Nomophobia and Alcohol, Tobacco, and Cannabis Consumption in Adolescents in Galicia.

This study aimed at exploring the association of nomophobia with alcohol, tobacco, and/or cannabis consumption among high school students. We carried out a cross-sectional study among high school and vocational training students in Galicia, Northwest Spain (N = 3,100). Collected data included nomophobia, sociodemographic variables, and alcohol, tobacco, and cannabis consumption. Nomophobia was measured using the validated Nomophobia Questionnaire. Adjusted odds ratios (ORs) and their 95 percent confidence intervals (CIs) were estimated using generalized linear mixed models. More than a quarter of the adolescents (27.7 percent) had nomophobia. We found an association between nomophobia and a high level of tobacco smoking in the last month in boys (OR = 2.16; 95 percent CI: 1.55-3.03). Nomophobia was also associated with higher odds of binge drinking in both genders (girls: OR = 1.86; 95 percent CI: 1.61-3.52; boys: OR = 2.29; 95 percent CI: 1.68-3.13) and with cannabis consumption in boys (OR = 1.74; 95 percent CI: 1.07-2.81). Our findings highlight the importance of a comprehensive investigation of the factors underlying alcohol, tobacco, and cannabis consumption in the adolescent population.

Youth Assets and Alcohol, Tobacco, and Other Drug Use: The Importance of Family Structure.

This research analyzed data from the Youth Asset Study (YAS), a 4-year longitudinal investigation designed to examine the prospective influence of youth assets, which are believed to influence behavior at the individual, family, and community levels, on youth risk behaviors. The purpose was to determine if specific youth assets (e.g., responsible choices, family communication, community involvement) differentially protected adolescents from alcohol, tobacco, and other drug use (ATODU) according to family structure (one-parent and two-parent households). Five waves of data were collected annually over four years from a racially/ethnically diverse sample of adolescents (N = 722, 51.5% male, baseline mean age = 14.1 years). Pearson chi-square tests for independence were used to test for significant differences in the prevalence of assets between one-parent and two-parent households. Generalized linear mixed models were used to identify prospective associations between 17 youth assets and ATODU while stratifying by family structure and controlling for sociodemographic characteristics. Compared to adolescents living in one-parent households, adolescents living in two-parent households were significantly more likely to possess six of 17 assets. Among adolescents living in one-parent households, those who possessed any one of eight youth assets were significantly less likely to use ATODU. Among adolescents living in one-parent households, those with any one of seven assets were significantly less likely to use ATODU. Family- and community-level assets had the most significant asset/ATODU associations for adolescents living in one-parent households (AORs ranged from 0.23 to 0.61). Individual-level assets had the most significant asset/ATODU associations for adolescents living in two-parent households (AORs ranged from 0.38 to 0.60). The results suggest that developing asset-based interventions tailored to the adolescents' family structure may be useful in preventing adolescents from engaging in ATODU.

Parental Phubbing and Adolescent Smartphone Addiction: Depression and Perceived School Climate Matter.

This study investigated the association between parental phubbing and adolescents' smartphone addiction, the mediating role of depression, and the moderating role of perceived school climate in the association. Seven hundred forty-two Chinese adolescents (Mage = 12.97, SD = 0.64, 45.55 percent female) were recruited and self-reported questionnaires were administered. Results indicated that parental phubbing was positively associated with adolescents' smartphone addiction. Depression partially mediated the above relation. Further, perceived school climate moderated the relation between parental phubbing and depression, such that the positive association between parental phubbing and depression was stronger among adolescents who perceived their school climate as more negative (vs. positive). The findings deepened our understanding of the relation between parenting behaviors and adolescents' smartphone addiction and implications for interventions and practices were discussed.

Evaluation of Effectiveness of the Unplugged Program on Gambling Behaviours among Adolescents: Study Protocol of the Experimental Controlled Study "GAPUnplugged".

Gambling risk behaviour is an emerging problem among adolescents. "Unplugged" is an effective Social Influence curriculum for preventing substance use among students. This study aims to develop and test a new component focused on gambling added to the Unplugged program. Schools of Piedmont region and Rome city were invited to participate in the study. A self-completed anonymous questionnaire including questions on socio-demographic characteristics, addictive behaviours, beliefs, attitudes and risk perceptions about gambling, normative perceptions, parental practices, school climate, refusal skills, impulsiveness, self-esteem, antisocial behaviours and sensation seeking was prepared for baseline and follow-up surveys. The protocol of the study was submitted and approved by the Novara Ethical Committee and registered in ClinicalTrials.gov (NCT05630157, Protocol ID: 080.742, 11/17/2022). Twenty-nine schools accepted to participate in the study. Sixty-three classes (1325 students) satisfied the eligibility criteria for intervention and were allocated to the intervention arm, and the other 61 (1269 students) were allocated to the control arm. Because of drop-out, absentees, refusals, and invalid questionnaires, data on 1874 students (998 in the intervention and 876 in the control arm), were available for the analysis at baseline. Data management of follow-up questionnaires is in progress. Results of the present study will be useful to clarify the effectiveness of prevention interventions in reducing gambling behaviours among adolescents. Moreover, this will be the first experience of evaluating a new component focused on a different risk behaviour, added to a curriculum previously shown as effective on other risk behaviours.

[Childhood, adolescence and the risk of addiction: a developmental perspective]. / Enfance, adolescence et risque d'addiction : une perspective développementale.

The period between the ages of 0 and 25 is a crucial phase in human development, during which many aspects of physical, psychological, personality, behavioral and health development take place. Important neurobiological changes during adolescence play a key role in their natural propensity to seek reward, putting them at greater risk of different kind of addictive behaviours. In addition, childhood adversity can foster the emergence of vulnerabilities which, for some, increases the risk of addiction by the time they reach adolescence. This article describes the normal development of the brain from childhood to adulthood, and its influence on addictive behaviours.

La période entre 0 et 25 ans est une phase cruciale du développement humain, au cours de laquelle de nombreux aspects physiques, psychologiques, de la personnalité, du comportement et de la santé se forment. D'importants changements neurobiologiques durant l'adolescence jouent un rôle essentiel dans la propension naturelle des jeunes à rechercher la récompense, ce qui les rend plus à risque de différents types de comportements addictifs. De plus, l'adversité rencontrée pendant l'enfance peut favoriser l'émergence d'une vulnérabilité augmentant, pour certains, le risque d'addictions lorsqu'ils atteignent l'adolescence. Cet article décrit le développement normal du cerveau de l'enfance à l'âge adulte ainsi que l'influence de ce dernier sur les comportements en lien avec les addictions.

[Screens and adolescence: what issues for the Z generation?] / Écrans et adolescence : quels enjeux pour la Génération Z ?

Digital media and screens are ubiquitous in the daily lives of adolescents. The screen-addicted portrait of young people has gained public attention, and health professionals are often consulted about the impact of screen use on teenagers' physical and mental health. Scientific evidence suggests that screen use is associated with risks and benefits that need to be weighed up in a nuanced way. This paper takes a critical look at the issue of screen time and at the models for understanding a problematic screen use. These considerations underline the importance of adopting a contextual understanding of screen use in adolescence.

Les médias numériques sont omniprésents dans la vie quotidienne des adolescent-es. La figure de l'adolescent-e « addict-e ¼ aux écrans est devenue un sujet de préoccupation dans l'opinion publique et il est fréquent que les professionnel-les de la santé soient sollicité-es pour répondre aux interrogations sur l'impact de l'utilisation des écrans sur la santé mentale et physique des jeunes. Les données scientifiques indiquent que l'usage des écrans est associé à des risques et des bénéfices qu'il s'agit d'évaluer de manière nuancée. Dans cet article, nous discutons en particulier et de façon critique du temps d'écran et des modèles de compréhension de l'usage problématique de celui-ci. Ces réflexions nous amènent à souligner l'importance d'adopter une compréhension contextualisée de cet usage à l'adolescence.

A latent class analysis of adolescent dating violence: Associations with daily conflict management.

BACKGROUND: Adolescent dating violence (ADV) is a major public health concern experienced by more than half of adolescents. Previous studies have found considerable diversity in patterns of ADV and suggest that its various forms often occur concurrently and reciprocally within adolescent dating relationships. While multiple robust distal correlates of ADV have already been established, research on situational factors, such as conflict-related variables, is still sparse. OBJECTIVE: This study aimed to identify patterns of ADV based on the co-occurrence of different types of ADV victimization and perpetration. Multiple correlates of these ADV patterns were examined, including daily conflict-related factors (e.g., occurrence, resolution). METHODS: A sample of 216 adolescents (M = 17.03 years; SD = 1.49) who were currently involved in a dating relationship completed a baseline assessment followed by 14 consecutive daily diaries. RESULTS: Latent class analysis revealed five classes, including Low violence (21.8 %), Emotional violence (50.9 %), Emotional and sexual violence (13 %), Psychological violence and control (7.9 %), and Multiple violence (6.5 %). Demographic, relationship, distal, and daily conflict-related indicators differentiated the classes. Findings indicated that youth in the Psychological violence and control and Multiple violence classes were involved in longer-lasting relationships and displayed higher externalized problems and emotion dysregulation, more frequent experiences of childhood traumas, and, notably, more difficulties in managing daily conflicts. CONCLUSION: Adolescence is a crucial time to reduce the onset, persistence, and adverse consequences of ADV. By identifying situational conflict-related factors associated with ADV victimization and perpetration, this study can inform important prevention efforts.

Substance Use, Suicidal Thoughts, and Psychiatric Comorbidities Among High School Students.

This cross-sectional study evaluates the dose-dependent association between alcohol, cannabis, and nicotine use and psychiatric symptoms among participants in the Substance Use and Risk Factor Survey and the Youth Risk Behavior Survey.

Video games and Facebook addiction among Tunisian adolescents: prevalence and associated factors.

OBJECTIVES: As social media and online gaming technology have developed very rapidly over the last two decades, their paired issues are of growing concern worldwide. The aim of our study was to assess the prevalence of video game and Facebook addiction and its predictive factors among Tunisian in school adolescents. METHODS: We conducted a cross-sectional study among in school adolescents in Sousse, Tunisia, over the first academic term of the 2019-2020 school year using a self-administered questionnaire to a randomly selected representative sample of 1,353 students. The valid Arabic version of the Bergen Facebook Addiction Scale (BFAS), the Video Game Addiction Scale (GAS-7), the Beck Depression Inventory Short Form (13 items) and the Screen for Child Anxiety Related Disorders (SCARED-C) were used to assess facebook addiction disorder (FAD), internet gaming disorder (IGD), depression and anxiety respectively. RESULTS: More than one in four pupils (26.1 %; CI 95 %: 23.8-28.4 %) were identified as problematic video game users and almost a third of participants (32.5 %; CI 95 %: 30-35 %) reported FAD. IGD was significantly associated with FAD (p<0.001). Likewise, pupils exhibiting depressive symptoms as well as those with anxiety symptoms were significantly more likely to be problematic video games and Facebook users (p<0.001 for each). Being addicted to Facebook (AOR=1.83, 95 % CI: 1.18-2.81), experiencing anxiety disorders (AOR=2.43, 95 % CI: 1.52-3.88), being male (AOR=2.51, 95 % CI: 1.95-3.23) and spending more than 4 h per day surfing the net (AOR=2.55, 95 % CI: 1.65-3.96) were the determinants of IGD in the multivariate analysis. Similarly, being addicted to video games (AOR=1.82, 95 % CI: 1.21-2.73), experiencing anxiety disorders (AOR=1.85, 95 % CI: 1.20-2.86), having experienced academic failure (AOR=1.73, 95 % CI: 1.16-2.56), and spending more than 4 h per day on social media (AOR=3.75, 95 % CI: 2.38-5.90) were the predictors of FAD. CONCLUSIONS: The prevalence of problematic use of video games and Facebook is alarmingly high. Identifying risk factors can help screen high-risk adolescents. We need additional prevention measures addressing not just adolescents, but all risk factors.

Longitudinal Associations Between Support and Prosocial Behavior Across Adolescence: The Roles of Fathers, Mothers, Siblings, and Friends.

Family members and friends can play an important role in adolescents' prosocial behavior. To better understand the relation between support and prosocial behavior in adolescence, it's important to conduct longitudinal studies that distinguish between within-dyad variance and between-dyad variance. The current study investigated longitudinal associations between adolescents' prosocial behavior, autonomy support, and emotional support from family and friends across adolescence. Across six annual years, 497 Dutch adolescents (284 boys; mean age T1 = 13.03 years, SDage = 0.46), fathers, mothers, siblings, and friends reported on their prosocial behavior. Adolescents also reported on perceived autonomy and emotional support. Between-dyads almost all associations of support and prosocial behavior of family members and friends with adolescents' prosocial behavior were significant, with higher levels of adolescents' prosocial behavior being associated with higher levels of prosocial behavior and support from fathers, mothers and friends. Within-dyads, several concurrent associations were significant, but within-dyads links between prosocial behavior and autonomy support are particularly driven by adolescent-mother or adolescent-sibling effects. This study highlights processes that occurred either at the between-dyad level or at the within-dyad level, but that varied per relationship type and that adolescents are the main catalysts in within-dyads changes in prosocial behavior and support. Preregistration: This study was preregistered on 20 January 2020 at https://osf.io/vxkm3/?view_only=dca87fd1585c444ba5cd5a00c22280ae .
