An exploratory analysis of loneliness dimensions and problematic use of social networks in adolescents
Adolescent loneliness represents a growing global public health concern that coincides with the widespread adoption of digital technologies. Recognising the complexity of loneliness experiences, this study examined the psychometric properties of the Perth A-loneness Scale (PALs) in a Spanish speaking sample of adolescents and investigated the relationships between distinct facets of loneliness and problematic social networking site use (PSNU). A …
Experiences of victimization, maladaptive schemas, and the mediating role of resilience in adolescents
Background Numerous studies have established the relationship between peer victimization and maladaptive schemas. Some studies indicate that resilience mediates between victimization and psychological distress, although there is a gap in the literature on the role of resilience in the formation of maladaptive schemas. Aim This study aimed to analyze the role of resilience as a mediator between peer victimization, cybervictimization, and maladapti…
Fear of Missing Out in an Online Context and Dysfunctional Risks in Adolescents
Fear of missing out (FoMO) is a problematic kind of attachment related to the distress caused by knowing that others are having rewarding experiences of which one is not a part. Although this feeling can negatively impact the lives of adolescents, the relationship between FoMO and other risks of dysfunctional use of the Internet in this age range is little explored. Furthermore, there is a gap in the online FoMO assessment instruments for this ag…

Profiles of social networking site use and problematic use among adolescents / Perfiles de uso de las redes sociales y uso problemático entre adolescentes
Adolescents’ use of social networks has increased exponentially. Therefore, considerable interest in studying the motives for using social network sites (SNS) and the relationships between these motives and problematic SNS use (PSNU) in adolescents has arisen. This study aimed to examine the relationships between adolescents’ motives for SNS use, frequency of use, numbers of SNS used and PSNU. A total of 1,775 students (50.4% female) aged 11–19 (…
The moderating effect of understanding advertising intent on the relation between advertising recognition and problematic use of loot boxes among minors
The use of loot boxes has been compared to gambling due to its random nature, with the consequent risk of being conceived as an ordinary activity implemented in the daily routine. One of the factors contributing to these gambling behaviors is exposure to gambling advertisements. It is essential to protect children and adolescents from prejudicial advertising, since due to their psycho-evolutionary development, advertising makes them impressionabl…
Peer cybervictimization and cyberaggression as a function of developmental stage during adolescence
Peer cybervictimization and cyberaggression are educational and social concerns which have been extensively studied during adolescence but there is less research conducted specifically across all stages of adolescence (early, middle, late, and emerging adulthood). The objective was to analyse the prevalence of cybervictimization and cyberaggression, the roles, and the associated behaviors, depending on the stages of adolescence. The sample was co…
Dysfunctional risks of the internet and their overlap in the different stages of adolescence
The use of the internet is a normative phenomenon associated with problems for younger people. The dysfunctional risks are those in which there is a problematic use of technologies that generates negative consequences. General Problematic Internet Use (GPIU) is the most prevalent, while Internet Gaming Disorder (IGD) and Online Gambling Disorder (OGD) are less prevalent, perhaps because they are Clinical problems and notably more severe. They hav…
Online and offline dating violence
Background Violent behaviors in romantic relationships among adolescents and young people are pressing social matter as they have an effect on both victims and aggressors. Moreover, in the last decades, new forms of harassment, control, and abuse through social networks and mobile phones have arisen. Therefore, now forms of online and offline dating violence coexist. Objectives The aim was to analyze the prevalence rates by sex and age and the co…

Loot box purchases and their relationship with internet gaming disorder and online gambling disorder in adolescents
In recent years, the video game industry has introduced Loot Box (LB), a new type of microtransaction in which a gamer uses real currency to purchase a random virtual item within a video game. Recently, LBs became more widespread and there is evidence suggesting their similarity to online gambling. Although some studies have investigated the association between LBs with disordered gaming and disordered gambling, very few have done so with clinica…
Epidemiology of peer cybervictimization and its relationship with health‐related quality of life in adolescents
INTRODUCTION: Research focused on the association between peer cybervictimization and declining health-related quality of life (HRQoL) is scarce. Currently, few longitudinal studies find an association between these phenomena, and none focus on cybervictimization profiles. The main objectives are: (1) to analyze the point and period prevalence, and incidence of cybervictimization profiles (uninvolved, new, ceased, intermittent, and stable cybervi…
Profiles of problematic social networking site use
In recent years, increasing interest in social networking site (SNS) use has resulted in a large body of research examining addiction to SNSs. The aim of this study was to cross-culturally validate a Spanish adaptation of the Problematic Social Networking Site Use Scale (PSNUS) based on the General Problematic Internet Use Scale (GPIUS-2) and to stablish profiles by using latent profile analysis (LPA) to compare the proportion of problematic use …
Solicitation and Sexualized Interactions of Minors with Adults
Sexual solicitation and sexualized interaction with minors by adults constitute one of the most pernicious risks of the Internet. Little is known about the age range in which this phenomenon is most prevalent or the relationship and overlap of this problem with other risks, such as peer-to-peer cybervictimization and cyber dating abuse. Additionally, little empirical evidence exists on whether the overlap between these types of online victimizati…
Bidirectional Relationships Between Cyberbystanders' Roles, Cyberbullying Perpetration, and Justification of Violence
Bystanders play a key role in understanding the phenomenon of cyberbullying (CB). The main aim of this study is to explore longitudinal bidirectional relationships among cyberbystanders' reaction, CB perpetration, and CB justification. Participants were 1,105 adolescents (56.7% girls; Mage = 13.56, SD = 1.21) who answered self-reported questionnaires about CB perpetration, CB justification, and cyberbystanders' reaction at two measurement periods…
Loot boxes in Spanish adolescents and young adults
In recent years, the video game industry has introduced the possibility of buying virtual random goods (e.g., loot boxes) in electronic games using money through microtransactions, which are becoming more widespread and potentially akin to gambling. Although previous research has linked loot boxes with problematic gaming and gambling behaviors, there are very few studies that relate them to the clinical indicators of these problems. The overall g…

Are Gifted Students More Victimized than Nongifted Students? A Comparison in Prevalence and Relation to Psychological Variables in Early Adolescence
The objective of this study is to compare the prevalence of bullying victimization and perpetration between a sample of gifted students and a sample of nongifted students, and their relationship in both groups with depression, stress, anxiety, and health-related quality of life (HRQoL). A cross-sectional design was performed with two comparison groups: 449 Spanish adolescents identified as gifted ( M age = 11.72, S D = 1.89) and 950 nongifted Spa…
Epidemiology of Cyber Dating Abuse Victimization in Adolescence and Its Relationship With Health-Related Quality of Life
There is currently no evidence of the relationship between cyber dating abuse (CDA) and health-related quality of life (HRQoL), especially from a longitudinal perspective. The objectives were: a) to analyze the point and period prevalence, incidence, and score changes over time of victimization by CDA; b) to compare HRQoL in the different categories of victims of CDA (nonvictims, new, ceased, intermittent, and stable victims). A three-wave longit…
An Exploratory Analysis of Different Problematic Internet Use Profiles in Cybervictims, Cyberbullies, and Cyberbully Victims
The Internet has brought about a paradigm shift in the lives of many people, especially adolescents. While it has opened great possibilities, it has also led to various risks such as cyberbullying and problematic Internet use (PIU). These two constructs have been extensively researched individually and jointly, but the existence of different profiles of problematic use according to the role a person assumes in the context of cyberbullying has not…

Health-Related Quality of Life and Cumulative Psychosocial Risks in Adolescents
Psychosocial risks can negatively affect adolescents' physical, psychological, and social health. Grounded on the cumulative risk theory, the objective of this study was to analyze the differences in health-related quality of life (HRQoL) depending on the accumulation of several psychosocial risks (bullying, cyberbullying, cyberdating abuse, sexting, online grooming, and problematic Internet use). The participants were 3,212 Spanish adolescents (…
Internet Risks
The advance of digital media has created risks that affect the bio-psycho-social well-being of adolescents. Some of these risks are cyberbullying, cyber dating abuse, sexting, online grooming and problematic Internet use. These risks have been studied individually or through associations of some of them but they have not been explored conjointly. The main objective is to determine the comorbidity between the described Internet risks and to identi…

Cyberbullying in Gifted Students
The differential characteristics of gifted students can make them vulnerable to cyberbullying. There is very little empirical evidence about cyberbullying and giftedness. In the Spanish context, it is unexplored. The main goal of this work is to determine the prevalence of cyberbullying, its distribution in the different roles, and its relationship with other psychological variables. A cross-sectional study was performed with 255 gifted students …

Internet-Risk Classes of Adolescents, Dispositional Mindfulness and Health-Related Quality of Life
This study was primarily aimed at identifying classes of adolescents in relation to their probability of endorsing several risks associated with the Internet (cyberbullying victimization and perpetration, cyberdating abuse victimization, and perpetration, sexting, and grooming). The second objective was to examine a mediational model linking dispositional mindfulness, risk perception, exposure to antisocial content in the media, Internet-risk cla…
Spanish Validation of the Internet Gaming Disorder Scale–Short Form (IGDS9-SF)
Online gaming is a very common form of leisure among adolescents and young people, although its excessive and/or compulsive use is associated with psychological impairments in a minority of gamers. The latest (fifth) edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5, Section III) tentatively introduced Internet Gaming Disorder (IGD). Since then, a number of evaluation tools using the DSM-5 criteria have been developed, i…
Cyberaggression in Adolescents of Bolivia
Concern about the increase of cyberbullying underlies this study, which had four objectives: (1) to calculate the prevalence of cyberaggressors; (2) to compare non-cyberaggressors with cyberaggressors in other bullying/cyberbullying roles, in psychopathological symptoms, and in self-image of masculinity/femininity, happiness, and empathy; (3) to analyze whether cyberaggressors consulted with a psychologist more than non-cyberaggressors; and (4) t…
Design and Validation of the Brief Self Online Scale (SO-8) in Early Adolescence
For the Z-Generation, the Internet has become a very important experimentation laboratory for the discovery and validation of their identity. Despite the importance of the process of building the self in the adolescent, there are hardly any validated instruments that measure the self online. The aim of this research was to design and validate the Brief Self Online Scale (SO-8). A total of 843 students (384 boys, 45.6%), with an age range of 10 to…
