ADHD symptoms and callous-unemotional traits as predictors of violent media use in adolescence.

We investigated ADHD symptoms and CU traits as predictors of violent media use in adolescence, controlling for delinquency and ODD symptoms. The effects on of disinhibition and arousal to negative stimuli, core characteristics of ADHD symptoms and CU traits, and of gender were investigated. At age 15, 88 adolescents, 50 % boys reported on CU traits, ADHD symptoms and delinquency. Parents rated the adolescents' CU traits, ADHD- and ODD symptoms. At age 16, adolescents reported on their media habits and performed tests of disinhibition and arousal to negative stimuli. Boys had higher levels of CU traits and violent media use and girls had higher levels of arousal to negative pictures. CU traits and inattention symptoms predicted violent media use, the latter association applying only to boys, with CU traits being the strongest predictor. Low arousal to threat pictures explained variance in violent media use, above CU traits. Attraction to violent media seems affected by problem behaviors, with CU traits coming forth as especially important.

Which Came First? Assessing Transactional Relationships Between Children’s Violent Media Use and ADHD-Related Behaviors

This longitudinal study investigated transactional relationships between violent media use and attention-deficit/hyperactivity disorder (ADHD)–related behaviors among young children (ages 4-8 years). To investigate study hypotheses, we employed a random intercept cross-lagged panel model (RI-CLPM) using structural equation modeling with panel data from 890 children. Results provided evidence in support of a media selection process rather than media effects process, whereby an increase in a child’s ADHD-related behaviors predicted an increase in the child’s violent media use 1 year later. Results indicated that this longitudinal relationship was accounted for by within-child fluctuations over time rather than stable between-child differences. The findings highlight the importance of investigating transactional relationships as well as distinguishing between-person and within-person relationships.

The Content-based Media Exposure Scale (C-ME): Development and Validation

It is somewhat ironic that although youth today are saturated in media, no standardized instrument exists to measure individual's exposure to specific media content. Therefore, we developed and validated a scale to measure both the frequency and content of adolescents' media exposure which measures media exposure regardless of media channel: the Content-based Media Exposure Scale (C-ME). The C-ME includes 17 items that assess exposure to antisocial (8 items) and neutral (9 items) media content. The factor structure was investigated in three independent samples (N = 892; N = 748; N = 524). Model fit indices like CFA's and RMSEA showed good fit, for both types of content, and predictive and discriminant validity was assessed. Exposure to antisocial media content positively correlated with sensation seeking, trait aggressiveness, violent media use, and general media use. The C-ME proves a reliable and easy to use instrument that measures media exposure in today's (new) media landscape.

Media Violence and Adolescents’ ADHD-Related Behaviors: The Role of Parental Mediation

We examined the role of parental media mediation in the relationship between media violence and adolescents’ ADHD-related behaviors. Survey data from 1,017 adolescents (10–14 years) show that parents can play an important role in this relationship, depending on the media mediation strategies that they use (i.e., restrictive or active mediation) and how they apply these strategies (i.e., in a controlling, inconsistent, or autonomy-supportive way). Our findings support the notion that contextual factors are critical in understanding media effects, and provide directions for how parents can manage their adolescents’ violent media use, and possibly by extension, their ADHD-related behaviors.

Violent media exposure, aggression and CU traits in adolescence: Testing the selection and socialization hypotheses

We investigated the role of exposure to violent action for later aggression and for later callous-unemotional traits in a sample of Swedish adolescents (N = 77–85), testing the selection and socialization hypotheses. Adolescents reported on violent delinquency and on callous-unemotional (CU) traits at age 15, on their media habits at age 16 and on reactive and proactive aggression and CU traits at age 18. The socialization hypothesis was supported with regard to aggression, that is, violent delinquency did not affect consumption of violent action, but controlling for violent delinquency, consumption of violent action added to proactive aggression and, marginally, to reactive aggression. The selection hypothesis was supported with regard to CU traits, that is, high levels of CU traits predicted frequent consumption of violent action, but consumption of violent action did not affect later levels of CU traits. Frequent violent media use was associated with later aggression. The associations between CU traits and violent media need further study.

Violent Media Effects on Aggression: A Commentary from a Cross-Cultural Perspective

It is argued that, despite differences in cultural norms and practices, the evidence for a link between violent media use and aggression is remarkably consistent across different countries. Along with evidence that different operationalizations of violent media use also converge across countries, these findings strengthen the conclusion that violent media are a risk factor for aggression and validate the psychological explanations for these effects. However, we need comparative studies based on a consistent methodology and a theory-based selection of cultural difference variables to properly examine the potential impact of culture on the association between violent media use and aggression.

Media Managing Mood: A Look at the Possible Effects of Violent Media on Affect

The potential impact of violent media on children’s emotional well-being has been a source of controversy for several decades. To date evidence for a negative impact of violent media on emotional well-being has been mixed and increasingly connected to a “replication crisis” throughout psychological science. The current study examines concurrent and prospective relationships between violent media use and symptoms of depression and anxiety in a sample of 536 mostly Hispanic youth (309 males, age range 10–14). Youth and parents were surveyed regarding social environment, media use and mental health. 302 youth responded to a 1-year follow-up. Results indicated that neither violent television use nor violent video game use predicted anxiety or depression concurrently or depression prospectively with this sample. The impact of media violence use on child mood symptoms appears to be minimal. Further research may wish to focus on particular at-risk groups.

Media Violence and Children's ADHD-Related Behaviors: A Genetic Susceptibility Perspective

This study examined the relationship between media violence exposure and Attention-deficit/hyperactivity disorder (ADHD)-related behaviors. Using survey (parent-reported) and genetic data of 1,612 Dutch children (aged 5 to 9 years), we examined genetic disposition as a possible cause of individual differences in children's use of and susceptibility to media violence. The gene variant of interest was the 5-HTTLPR polymorphism, which has been associated with ADHD-related behaviors in previous research. Results showed that the long variant of the gene polymorphism was related to greater violent media use, which in turn was related to more ADHD-related behaviors. The 5-HTTLPR genotype did not moderate the effect of media violence on ADHD-related behaviors. This study provides insight into the role of genetic factors in media effects.

Media violence use as a risk factor for aggressive behaviour in adolescence

Whether exposure to violence in the virtual reality of the media has an impact on users’ aggressive behaviour has been a controversial issue in academic as well as public debate. This article summarises a programme of research conducted with adolescents in Germany that presents cross-sectional and longitudinal evidence for the association between violent media use and aggression. It provides experimental evidence in support of mediating variables, such as hostile attributional style, increased normative acceptance of aggression, and emotional desensitisation, which might explain the pathways from media violence use to aggression. In addition it presents the development and experimental evaluation of a theory-based intervention designed to reduce media violence use and decrease its link with aggressive behaviour. The findings are discussed in the context of a large international body of research that points to the causal role of violent media use as a risk factor for aggressive behaviour.

Long-Term Relations Among Prosocial-Media Use, Empathy, and Prosocial Behavior

Despite recent growth of research on the effects of prosocial media, processes underlying these effects are not well understood. Two studies explored theoretically relevant mediators and moderators of the effects of prosocial media on helping. Study 1 examined associations among prosocial- and violent-media use, empathy, and helping in samples from seven countries. Prosocial-media use was positively associated with helping. This effect was mediated by empathy and was similar across cultures. Study 2 explored longitudinal relations among prosocial-video-game use, violent-video-game use, empathy, and helping in a large sample of Singaporean children and adolescents measured three times across 2 years. Path analyses showed significant longitudinal effects of prosocial- and violent-video-game use on prosocial behavior through empathy. Latent-growth-curve modeling for the 2-year period revealed that change in video-game use significantly affected change in helping, and that this relationship was mediated by change in empathy.

Fronto-parietal regulation of media violence exposure in adolescents: a multi-method study

Adolescents spend a significant part of their leisure time watching TV programs and movies that portray violence. It is unknown, however, how the extent of violent media use and the severity of aggression displayed affect adolescents' brain function. We investigated skin conductance responses, brain activation and functional brain connectivity to media violence in healthy adolescents. In an event-related functional magnetic resonance imaging experiment, subjects repeatedly viewed normed videos that displayed different degrees of aggressive behavior. We found a downward linear adaptation in skin conductance responses with increasing aggression and desensitization towards more aggressive videos. Our results further revealed adaptation in a fronto-parietal network including the left lateral orbitofrontal cortex (lOFC), right precuneus and bilateral inferior parietal lobules, again showing downward linear adaptations and desensitization towards more aggressive videos. Granger causality mapping analyses revealed attenuation in the left lOFC, indicating that activation during viewing aggressive media is driven by input from parietal regions that decreased over time, for more aggressive videos. We conclude that aggressive media activates an emotion-attention network that has the capability to blunt emotional responses through reduced attention with repeated viewing of aggressive media contents, which may restrict the linking of the consequences of aggression with an emotional response, and therefore potentially promotes aggressive attitudes and behavior.

The role of violent cognition in the relationship between personality and the involvement in violent films and computer games

The study investigates the relationship between empathy and attitudes towards violence and real-life exposure to violent films and computer games. It is hypothesised that low empathy and attitudes that predispose people towards violence are more strongly related to exposure to violent films and computer games than to superordinate personality traits (e.g., EPQ psychoticism, extraversion, antisocial personality traits), or subtraits, such as sensation-seeking. Four hundred and thirty-three students in further education completed three personality questionnaires, a questionnaire of attitudes towards violence, and reported on their use of violent computer games, films and videos. Multivariate analyses in the form of ordinary least squares (OLS) models were used to test the primary hypotheses. Acceptance of violence, as measured by the Maudsley Violence Questionnaire (MVQ), was the strongest and most consistent predictor of violent media use. Superordinate personality traits were generally fully mediated by acceptance of violence. The findings emphasise the importance of general acceptance of violence in the consumption of violent games and films. Some gender differences emerged; particularly in relation to the use of violent computer games. Empathy had no significant effects for either males or females.

Family Conflict and Violent Electronic Media Use in School-Aged Children

Using a national sample of children aged 6 to 12 (N = 1,075), this study examined the relative merits of 3 theoretical perspectives on the relation between family conflict and children's use of electronic media (television and electronic games with violent content): (a) the family context hypothesis, whereby family conflict is positively related to violent electronic media use because family tensions will be reflected in children's interest in media with violent content; (b) the reaction hypothesis, whereby family conflict is positively related to nonviolent media use because children seek out nonviolent media content as a reaction against conflict in their family environment; and (c) the escape hypothesis, whereby family conflict is positively related to total electronic media use because children use media to escape family conflict regardless of content. Results supported the family context hypothesis. There was no support for the reaction and escape hypotheses.

Violent Media Content and Aggressiveness in Adolescents

Theory and research on media violence provides evidence that aggressive youth seek out media violence and that media violence prospectively predicts aggression in youth. The authors argue that both relationships, when modeled over time, should be mutually reinforcing, in what they call a downward spiral model. This study uses multilevel modeling to examine individual growth curves in aggressiveness and violent media use. The measure of use of media violence included viewing action films, playing violent computer and video games, and visiting violence-oriented Internet sites by students from 20 middle schools in 10 different regions in the United States. The findings appear largely consistent with the proposed model. In particular, concurrent effects of aggressiveness on violent-media use and concurrent and lagged effects of violent media use on aggressiveness were found. The implications of this model for theorizing about media effects on youth, and for bridging active audience with media effects perspectives, are discussed.
