Peer cybervictimization and cyberaggression as a function of developmental stage during adolescence: A preliminary study.

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 composed of 7295 non-university Spanish adolescents, between 11 and 22 years old from 47 schools. The frequency of cybervictimization and cyberaggression was 22.5 % and 15 %, respectively. The highest frequencies are found in late adolescence and the lowest in emerging adulthood. Mainly, involvement increases from early to late adolescence and decreases in emerging adulthood. The magnitude of cybervictimization and cyberaggression behaviors for the roles of pure cybervictim and pure cyberaggressor is similar through all stages.

Solicitation and Sexualized Interactions of Minors with Adults: Prevalence, Overlap with Other Forms of Cybervictimization, and Relationship with Quality of Life.

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 victimization affects health-related quality of life (HRQoL). This study aimed to: 1) analyze the prevalence of sexual solicitation and interaction according to sex and stage of adolescence; 2) relate this problem to other forms of online victimization (cybervictimization and cyber dating abuse); 3) analyze the overlap between these forms of online victimization and differences in HRQoL scores. A cross-sectional and analytical study with 3,578 adolescents (52.7% girls) aged between 10-15 years was carried out. Of the adolescents in the study sample, 12.6% (n = 448) had received sexual requests and 6.4% (n = 230) had interacted sexually with adults. Sexual solicitation was most common among girls in middle adolescence. Of the participants, 33.9% (n = 1,216) had been involved in some form of online victimization. Peer cybervictimization and cyber dating abuse were positively and significantly correlated with sexualized solicitation/interactions with adults. Victims with the overlapping of all three types of online victimization (2.7%, n = 98) presented the lowest HQRoL scores (p < .001).

La solicitación e interacción sexual con menores por parte de adultos constituyen uno de los riesgos más perniciosos de Internet. Se sabe poco sobre la franja de edad en el que es más frecuente o sobre la relación y el solapamiento de este problema con otros riesgos, como la cibervictimización entre iguales y el abuso online en la pareja. Además, existen pocas evidencias empíricas sobre si el solapamiento entre estos tipos de victimización afecta a la calidad de vida relacionada con la salud (CVRS). Los objetivos de este estudio fueron: 1) analizar la prevalencia de la solicitación/interacción sexual en función del sexo y la etapa de la adolescencia, 2) relacionar esta problemática con la cibervictimización entre iguales y el abuso online en la pareja, 3) analizar el solapamiento entre estas formas de victimización online y sus diferencias en las puntaciones de CVRS. Se trata de un estudio transversal y analítico con 3,578 adolescentes (52.7% chicas) entre 10-15 años. El 12.6% (n = 448) habían recibido solicitaciones sexuales y el 6.4% (n = 230) había interactuado sexualmente con adultos. La solicitación sexual fue más frecuente en chicas en la adolescencia media. Un 33.9% (n = 1,216) había sufrido algún tipo de victimización online. La cibervictimización entre iguales y el abuso online en la pareja correlacionaron positiva y significativamente con solicitaciones/interacciones sexualizadas con adultos. Las víctimas que solaparon los tres tipos de victimización online (2.7%, n = 98) presentaron las puntuaciones de CVRS más bajas (p < .001).

Domoic Acid Oxidative Effects on the Microalgae Phaeodactylum tricornutum.

Domoic acid (DA) is a natural occurring marine biotoxin. Oxidative stress generation due to DA exposure was reported in animals, but little is known on the phytoplankton community. The aim of this work was to verify whether exposure to DA in the marine diatom Phaeodactylum tricornutum favors reactive oxygen species (ROS) generation in the intracellular environment modifying its antioxidant capacity. Active species production, non-enzymatic antioxidant content, and antioxidant enzyme activities over the three growth phases of P. tricornutum exposed to 64 µM DA were evaluated. Results obtained in exponential growing cells showed a time-depending seven-fold increase in the 2',7' dichlorofluorescein diacetate dye oxidation rate. Superoxide dismutase and catalase activities showed a two-fold increase, and glutathione related enzymes activities were also significantly increased in treated diatoms as compared to controls. However, glutathione and ascorbate contents significantly decreased after incubation of the cells with DA. Similar effects were observed in latent and stationary phases of cell development. These results showed that DA could cause a severe oxidant-dependent impact on a non-toxic algae.

The Protective Role of Dispositional Mindfulness on Cyber Dating Abuse: A 6-Month Longitudinal Study.

Dispositional mindfulness has been related to a decreased propensity to aggressive behaviors toward others, including dating partners. Nevertheless, research in the context of romantic relationships is scarce, based on cross-sectional designs and offline (face to face) aggression. Thus, this 6-month longitudinal study seeks to fill a gap in the literature by examining the predictive role of dispositional mindfulness facets (observing, describing, acting with awareness, non-judging, and non-reacting) in the perpetration of cyber dating abuse (CDA) behaviors in adolescents. The moderator role of the dispositional mindfulness facets in the perpetuation over time of cyber aggression toward the partner was also explored. Participants were 501 high school students (54.1% girls; mean age: 14.17 years, SD = 1.39) from different regions of Spain who completed self-report measures about CDA and dispositional mindfulness at two time points with a 6-month interval between them. Path analysis showed that the acting with awareness mindfulness facet predicted a decrease in the perpetration of CDA 6 months later. Moreover, non-reacting showed a moderator role in the perpetuation over time of CDA. In particular, adolescents with higher scores on non-reacting, evidenced a lower perpetuation of CDA. Mindfulness-based interventions can be a valuable tool in preventing cyber aggression that occurs in adolescent dating relationships.

Epidemiology of peer cybervictimization and its relationship with health-related quality of life in adolescents: A prospective study.

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 cybervictims); (2) to study the relationship between cybervictimization and HRQoL over time; (3) to determine the longitudinal impact on the HRQoL of each type of profile. METHODS: A prospective study was conducted in three waves over 13 months. A total of 1142 adolescents aged 11-18 years participated in all the waves (630 girls, 55.2%). RESULTS: The prevalence of victimization for the three waves was 21.6% (Wave 1; W1), 23.5% (W2), and 19.6% (W3), respectively. The period prevalence was 41.3%, and the accumulated incidence was 25.1%. It was found that 24% of the participants were new victims, 5.9% were intermittent victims, and 6% were stable victims. Being a cybervictim at W1 poses a relative risk of 1.73 [1.29-2.32], that is, a twofold increased risk of presenting a low HRQoL 13 months later compared to those who are not cybervictims. CONCLUSION: One in four adolescents became a new cybervictim during the 13 months of the study. The adolescents who presented poorer HRQoL were the stable cybervictims.

Problematic Internet use and Internet gaming disorder: Overlap and relationship with health-related quality of life in adolescents. / Uso problemático de Internet y trastorno de juego por Internet: Solapamiento y relación con la calidad de vida relacionada con la salud en adolescentes.

General Problematic Internet Use (GPIU) is a dysfunctional use of Internet handling and management in general. In contrast, Internet Gaming Disorder (IGD) is a specific behaviour linked to online videogames. Both problems are becoming common in adolescents, but they have hardly been studied simultaneously, and the joint relationship of the two constructs with Health-Related Quality of Life (HRQoL) is unknown. The general objective of this study is to analyse the relationship between GPIU and IGD and their association with HRQoL. The study is analytical and cross-sectional with 2,024 participants (46.4% boys, n = 939) from 16 schools of 7 Spanish regions. The mean age and standard deviation were 14.20±1.42, with a range of 11-18 years. The Spanish versions of the KIDSCREEN-10, the Revised Generalized and Problematic Internet Use Scale 2 and the Internet Gaming Disorder Scale were used. Of the total sample evaluated, 15.5% of the participants had high levels of GPIU, and 3.3% of video game players presented IGD. The dimensions of GPIU are strongly associated with those of IGD. HRQoL correlated significantly and negatively with all the dimensions of GPIU and IGD (p <.001). Participants who reported problems with GPIU or IGD, individually or conjointly, had significantly lower scores in HRQoL than those with no problems.

En cambio, el Trastorno de juego por Internet (IGD) es una conducta específica vinculada a los videojuegos en línea. Ambos problemas comienzan a ser frecuentes en adolescentes, pero apenas han sido estudiados simultáneamente ni se conoce el papel conjunto de ambos constructos sobre Calidad de vida relacionada con la salud (CVRS). El objetivo general de este estudio es analizar la relación entre el GPIU y el IGD y su asociación con la CVRS. El estudio es analítico y transversal con 2024 participantes (46,4% chicos, n = 939) procedentes de 16 colegios en 7 regiones españolas. La media de edad y desviación típica fue de 14,20±1,42 en un rango de 11-18 años. Se usaron las versiones españolas del KIDSCREEN-10, del Revised Generalized and Problematic Internet Use Scale 2 y del Internet Gaming Disorder Scale. Un 15,5% del total de la muestra evaluada reportó niveles altos de GPIU y un 3,3% de los jugadores de videojuegos presentó IGD. Las dimensiones del GPIU están altamente asociadas a las del IGD. La CVRS correlacionó significativa y negativamente con todas las dimensiones del GPIU y del IGD (p <,001). Los participantes que reportaron problemas en el GPIU o el IGD, individual o conjuntamente, presentan puntuaciones significativamente más bajas en la CVRS.

Relación entre el rasgo de atención plena (mindfulness) y el papel de los testigos de ciberacoso entre los adolescentes / Relationship between mindfulness trait and the role of cyberbullying witnesses among adolescents

El uso generalizado de Internet entre los adolescentes ha propiciado el ciberacoso. Los testigos desempeñan un papel fundamental en el mantenimiento y el fortalecimiento del acoso. El rasgo de atención plena (AP) se ha asociado con comportamientos prosociales, así cabe pensar que existe relación entre este rasgo y el papel adoptado por los testigos de ciberacoso. 2015 estudiantes de 11-19 años completaron medidas de ciberacoso, rasgo de AP y papel de espectador. Ante una situación de acoso online, el 74,3% se declaró a favor de la víctima y el 7,8% a favor del perpetrador. Para analizar las diferencias en el rasgo AP según el papel del espectador, se realizó un MANCOVA que resultó ser significativa para las siguientes facetas de atención plena: observar, describir, actuar con conciencia y no juzgar. El análisis no resultó significativo para la faceta de no reactividad. Las víctimas y los agresores obtuvieron puntuaciones más altas en la observación que aquellos que no apoyaron ni a la víctima ni al agresor. Se discuten las implicaciones y limitaciones. (AU)

The widespread use of the Internet among adolescents has led to cyberbullying. Bystanders play a vital role in sustaining and strengthening bullying. As trait mindfulness has been associated with prosocial behaviors, there is good reason to believe that there is a relationship between the mindfulness trait and the role adopted by cyberbullying bystanders. A cross-sectional study was employed with a sample of 2015 students aged 11-19 years. The participants completed the measures for cyberbullying, trait mindfulness, and their role as bystanders. The results revealed that 74.3% and 7.8% of them were identified as provictim and pro-perpetrator, respectively. MANCOVA was employed to analyze the differences in the characteristics of trait mindfulness according to the role of bystander with corrected age, and its use was significant for the following factors: Observing, describing, acting with awareness, and nonjudging. No significant differences were observed in the nonreactivity factor. Provictims and pro-perpetrators scored higher on observing than those who supported neither the victim nor the perpetrator. Implications and limitations are discussed. (AU)

Perfiles de redes sociales de estudiantes, necesidades psicológicas básicas, autoconcepto e intención de ser físicamente activo / Students' social media profiles, basic psychological needs, self-concept, and intention to be physically active

Este estudio transversal tuvo como objetivo identificar los perfiles de adicción a las redes sociales y si existe relación con las necesidades psicológicas básicas, el autoconcepto y la intención de ser físicamente activo. Participaron 276 estudiantes (115 hombres y 161 mujeres, Medad= 28,47; DT= 8,65) de 10 universidades españolas en un muestreo intencional. Se encontraron dos perfiles, uno caracterizado por puntuaciones altas en síntomas de adicción, uso social, uso friki y nomofobia, y otro caracterizado por puntuaciones extremadamente altas en síntomas de adicción, uso social, uso friki y nomofobia. Los resultados revelaron diferencias significativas en: autonomía, competencia y autoconcepto emocional. El segundo perfil mostró puntuaciones más bajas en todas esas medidas y tenían menor edad (M= 25,69; DT= 6,93) que los del primer perfil (M= 30,10; DT= 9,15). La presencia de niveles importantes de síntomas de adicción en ambos perfiles de la muestra sugiere crear intervenciones para prevenir los resultados desadaptativos de las adicciones en las redes sociales. (AU)

This cross-sectional study aimed to identify social networks addiction profiles and whether there is a relationship with basic psychological needs, self-concept and intention to be physically active. The participants were 276 Spanish University Students (115 men and 161 women, Mage= 28.47; SD= 8.65) from 10 different universities through incidental sampling. Two profiles were found: a profile characterized by high scores in addiction symptoms, social usage, geek treats and nomophobia; a profile characterized by extremely-high scores in addiction symptoms, social usage, geek treats and nomophobia. Results revealed significant differences between the profiles in autonomy, competence and emotional selfconcept. The second profile revealed higher scores in the aforementioned variables and showed lower age in their participants (M= 25.69; SD= 6.93) in comparison with the high social network profile (M= 30.10; SD= 9.15). The presence of important levels of addiction symptoms in both profiles of the sample suggests that interventions should be conducted to prevent the maladaptive outcomes of addictions in social media.

Loot box engagement: A scoping review of primary studies on prevalence and association with problematic gaming and gambling.

BACKGROUND: Loot boxes are an increasingly common type of random microtransaction in videogames. There is some concern about their expansion and entailed risks, especially among adolescents. The actual prevalence of engagement with loot boxes among child and adult population is uncertain, and there is still controversy over the nature of their relationship with problematic gaming and gambling. OBJECTIVES: The aims of this scoping review are to summarize the characteristics and findings of published primary empirical studies about the prevalence of engagement with loot boxes and/or their relationship with problematic gaming and gambling, taking in account the type of sample, time frame and measured variables. METHODS: This study follows the Joanna Briggs Institute's "Guidance for conducting systematic scoping reviews" and the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Three academic databases provided 299 articles. RESULTS: Sixteen primary empirical studies met the inclusion criteria for this review. All studies used cross-sectional designs, and most used convenience samples. Twelve study samples were comprised exclusively of gamers, and two were comprised of gamers and/or gamblers. Only six studies included adolescents. The annual prevalence rate of loot box purchases was higher for adult gamers than for adolescents (22.7%-44.2% and 20%-33.9%, respectively), but in studies with general population samples, the opposite was true (24.9% for players aged 13-14 versus 7.8% for adults). In general, the studies suggested a significant positive relationship between engagement with loot boxes and problematic gaming and gambling, but this may be related to the type of engagement (open/purchase/sell), and the characteristics of the study participants (male/female, adolescents/adults, gamers/gamers-gamblers/general population). CONCLUSIONS: This scoping review summarizes the results of recent empirical studies on engagement with loot boxes and discusses how methodological issues may affect their results and interpretation. Recommendations for future research are also provided.

Problematic online gambling among adolescents: A systematic review about prevalence and related measurement issues.

BACKGROUND AND AIMS: Despite its illegality among adolescents, online gambling is a common practice, which puts their mental health and well-being at serious risk. This systematic review summarises international scientific literature from the last 20 years on problematic online gambling among adolescents (11-21 years old) to determine its prevalence and to analyse related measurement issues. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed and a protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO, IC: CRD42020162932). Five academic databases were consulted, which resulted in an initial sample of 658 papers. RESULTS: Sixteen studies met the inclusion criteria for this review. All studies were cross-sectional and targeted students from elementary school, secondary school or university. Most followed a convenience sampling procedure. The primary measurement instruments used were the DSM-IV-MR-J and SOGS-RA. Between 0.77% and 57.5% of adolescents present some degree of problematic online gambling (problem, pathological or disordered) depending on the instruments used, the study samples and the timeframe analysed. Between 0.89% and 1% of adolescents exhibited an online gambling disorder. DISCUSSION AND CONCLUSION: There is a great heterogeneity in the methodology of the reviewed studies (samples, measurement instruments, cut-off points and criteria applied). The limited number of studies and the limited generalizability of their results suggest the need for further research and for development of specific instruments to assess different levels of problematic online gambling in representative samples of adolescents based on clinical 'gold standard' criteria and more accurate cut-off points.

Single and Combined Effects of Cypermethrin and UVR Pre-Exposure in the Microalgae Phaeodactylum Tricornutum.

Coastal marine microalgae are exposed to anthropogenic pollutants, including pesticides from aquaculture/agriculture/household uses. Some microalgae species, such as Phaeodactylum tricornutum, can induce and accumulate UV-absorbing compounds (UACs) upon ultraviolet radiation (UVR) exposure to prevent deleterious effects. Tolerance mechanisms activated by natural stressors might also protect organisms from anthropogenic stressors. This work assesses the effects of the insecticide cypermethrin (Cyp) and UVR in the marine microalgae P tricornutum. Considering the pro-oxidant properties of both stressors and UACs' induction in P tricornutum, lethal and sublethal effects of Cyp were tested in cultures with and without UVR acclimation. After a 24-h exposure to 10 µg L-1 of technical Cyp or culture medium, UACs, growth, glutathione-S-transferase activity (GST), sulfhydryl groups (SH-g), and lipid peroxidation (LPO) were analyzed. Results showed differences in terms of growth between Cyp and Cyp + UVR pre-exposure. UACs' content was induced after UVR acclimation and diminished after 24 h of growth in control and UVR pre-treated cultures, while levels remained constant under Cyp exposure. A single Cyp exposure exerted GST induction, SH-g depletion, and LPO increments. In UVR-acclimatized treatments, oxidative stress responses showed similar or more pronounced effects than the single chemical exposure, suggesting a potential additive effect of the UVR acclimation. The contrasting effects of Cyp + UVR observed between growth and biochemical responses suggest different compensatory mechanisms that need to be further investigated. Also, it highlights the need to include both lethal and sublethal endpoints to understand microalgae's tolerance and its significance in the multiple stressors' context.

A systematic review on nomophobia prevalence: Surfacing results and standard guidelines for future research.

BACKGROUND: Mobile phones allow us to stay connected with others and provide us a sense of security. We can work, chat with family and friends, take pictures, buy clothes or books, and even control home appliances. They play such a significant role in our lives that we feel anxious without them. In some cases, the relationship between humans and these communication devices have become problematic. Nomophobia (NMP) is the fear of becoming incommunicable, separated from the mobile phone and losing connection to the Internet. Since this social phobia was coined in the first decade of the XXI century, a growing number of studies have studied it and reported the prevalence of this technology-related problem. However, this research activity has generated mixed results regarding how we assess and report nomophobia and who may be at a higher risk of suffering or developing it. METHODS: We conducted a systematic review of 108 studies published in English and Spanish and collected them in Parsifal. We searched for assessment and prevalence data on nomophobia. Also, we looked at gender and age differences to identify risk factors and see if these differences exist and emerge worldwide. RESULTS: In this study, we find that women and younger individuals suffer more from nomophobia. The disparity in reporting the prevalence of nomophobia is enormous since the percentages of "at-risk" participants go from 13% to 79%, and participants suffering from it are between 6% and 73%, being the score in the range of 45.5 and 93.82. Within the group of nomophobic people, moderate cases vary between 25.7% and 73.3%, and severe cases, between 1% and 87%. Such disparity is due to differences in assessment criteria. Females and young people seem to be more vulnerable to nomophobia although methodological disparity makes it difficult to reach definitive conclusions. We conclude our review by recommending some common guidelines for guiding future research.

Effects of a Brief Preventive Intervention in Cyberbullying and Grooming in Adolescents / Los efectos de una intervención preventiva breve en ciberacoso y grooming en adolescentes

The development of brief and inexpensive interventions that reduce risky behaviors in adolescence constitute a challenge for current research. This study addresses the prevention of two online behavior problems in adolescents (cyberbullying and online grooming). Two pilot studies evaluated the effects of a 1-hour intervention, which combined self-affirmation (SA) with the incremental theory of personality (ITP), for cyberbullying and online grooming. Study 1 involved 339 adolescents (51% male, mean age = 14.12 years, SD = 0.70), who were randomly assigned to the SA + ITP intervention or one of two control conditions. Hierarchical regression analyses indicated that the SA + ITP intervention reduced the reciprocity between sexual solicitation and sexualized interaction with adults, as well as between cyberbullying victimization and perpetration. Study 2 included 214 adolescents (50.3% male, mean age = 14.06 years, SD = 0.96), who were randomly assigned to the SA + ITP or a control condition. Hierarchical linear modeling analyses indicated that the SA + ITP reduced the reciprocity between sexual solicitation and sexualized interaction with adults, and reduced cyberbullying perpetration. The studies provided preliminary evidence of the benefits of the SA + ITP intervention. (AU)

El desarrollo de intervenciones breves y económicas que reduzcan las conductas de riesgo en la adolescencia constituye un desafío para la investigación actual. Este estudio aborda la prevención de dos problemas de comportamiento online en adolescentes (ciberacoso y grooming en Internet). Dos estudios piloto evaluaron los efectos de una intervención de una hora que combinó autoafirmaciones (AA) con la teoría incremental de la personalidad (TIP) en el ciberacoso y el grooming. En el estudio 1 participaron 339 adolescentes (51% chicos, edad media = 14.12 años, DT = 0.70), que fueron asignados aleatoriamente a la intervención AA + TIP o una de dos condiciones de control. Los análisis de regresión jerárquica indicaron que la intervención AA + TIP redujo la reciprocidad entre la solicitud sexual y la interacción sexualizada con adultos, así como entre la victimización y la perpetración de ciberacoso. El estudio 2 incluyó a 214 adolescentes (50.3% chicos, edad media = 14.06 años, DT = 0.96), que fueron asignados aleatoriamente a AA + TIP o a una condición de control. Los análisis de modelos lineales jerárquicos indicaron que AA + TIP redujo la reciprocidad entre la solicitud sexual y la interacción sexualizada con adultos y redujo la perpetración de ciberacoso. Los estudios aportaron evidencia preliminar de las ventajas de la intervención AA + TIP. (AU)

Safety.Net: A Pilot Study on a Multi-Risk Internet Prevention Program.

Many programs exist to prevent bullying and cyberbullying. Nevertheless, despite evidence of the numerous overlapping risks of the Internet, programs that jointly and adequately address large sets of risks are not presently described in the scientific literature. This study's main objective was to assess the effectiveness of the Safety.net program in a pilot sample. This program prevents eight Internet risks: cyberbullying, sexting, online grooming, cyber dating abuse, problematic Internet use, nomophobia, Internet gaming disorder, and online gambling disorder. The Safety.net program comprises 16 sessions and 4 modules (digital skills, relational risks, dysfunctional risks, and change of attitudes and cognitions). Each session lasts one hour, but the program has a networked instructional design to recall previous content in later sessions. For its assessment, a pre/post-test repeated measures design with a control group and an intervention group was used. The study sample was 165 adolescents between 11 and 14 years old (M = 12.11, SD = 0.89). The intervention group demonstrated improvements compared to the control group concerning online grooming, problematic Internet use, Internet gaming disorder, and nomophobia. These results suggest that the Safety.net program is effective in preventing the increase of most of the assessed risks and that it reduces some of them with a small number of sessions.
