  abstract  = {NutzerInnen von gewalthaltigen Medien geben einerseits oftmals zu, dass sie fiktionale, gewalthaltige Medien konsumieren, behaupten jedoch gleichzeitig, dass dies nicht ihr Verhalten außerhalb des Medienkontexts beeinflusst. Sie argumentieren, dass sie leicht zwischen Dingen, die im fiktionalen Kontext und Dingen, die in der Realit{\"a}t gelernt wurden, unterscheiden k{\"o}nnen. Im Kontrast zu diesen Aussagen zeigen Metanalysen Effektst{\"a}rken im mittleren Bereich f{\"u}r den Zusammenhang zwischen Gewaltmedienkonsum und aggressivem Verhalten. Diese Ergebnisse k{\"o}nnen nur erkl{\"a}rt werden, wenn MediennutzerInnen gewalthaltige Lernerfahrungen auch außerhalb des Medienkontexts anwenden. Ein Prozess, der Lernerfahrungen innerhalb des Medienkontexts mit dem Verhalten in der realen Welt verkn{\"u}pft, ist Desensibilisierung, die oftmals eine Reduktion des negativen Affektes gegen{\"u}ber Gewalt definiert ist. Zur Untersuchung des Desensibilisierungsprozesses wurden vier Experimente durchgef{\"u}hrt. Die erste in dieser Arbeit untersuchte Hypothese war, dass je h{\"a}ufiger Personen Gewaltmedien konsumieren, desto weniger negativen Affekt zeigen sie gegen{\"u}ber Bildern mit realer Gewalt. Jedoch wurde angenommen, dass diese Bewertung auf Darstellungen von realer Gewalt beschr{\"a}nkt ist und nicht bei Bildern ohne Gewaltbezug, die einen negativen Affekt ausl{\"o}sen, zu finden ist. Die zweite Hypothese bezog sich auf den Affekt w{\"a}hrend des Konsums von Mediengewalt. Hier wurde angenommen, dass besonders Personen, die Freude an Gewalt in den Medien empfinden weniger negativen Affekt gegen{\"u}ber realen Gewaltdarstellungen zeigen. Die letzte Hypothese besch{\"a}ftigte sich mit kognitiver Desensibilisierung und sagte vorher, dass Gewaltmedienkonsum zu einem Transfer von Reaktionen, die normalerweise gegen{\"u}ber gewalthaltigen Reizen gezeigt werden, auf urspr{\"u}nglich neutrale Reize f{\"u}hrt. Das erste Experiment (N = 57) untersuchte, ob die habituelle Nutzung von gewalthaltigen Medien den selbstberichteten Affekt (Valenz und Aktivierung) gegen{\"u}ber Darstellungen von realer Gewalt und nichtgewalthaltigen Darstellungen, die negativen Affekt ausl{\"o}sen, vorhersagt. Die habituelle Nutzung von gewalthaltigen Medien sagte weniger negative Valenz und weniger allgemeine Aktivierung gegen{\"u}ber gewalthalten und nichtgewalthaltigen Bildern vorher. Das zweite Experiment (N = 103) untersuchte auch die Beziehung zwischen habituellem Gewaltmedienkonsum und den affektiven Reaktionen gegen{\"u}ber Bildern realer Gewalt und negativen affektausl{\"o}senden Bildern. Als weiterer Pr{\"a}diktor wurde der Affekt beim Betrachten von gewalthaltigen Medien hinzugef{\"u}gt. Der Affekt gegen{\"u}ber den Bildern wurde zus{\"a}tzlich durch psychophysiologische Maße (Valenz: C: Supercilii; Aktivierung: Hautleitreaktion) erhoben. Wie zuvor sagte habitueller Gewaltmedienkonsum weniger selbstberichte Erregung und weniger negative Valenz f{\"u}r die gewalthaltigen und die negativen, gewalthaltfreien Bilder vorher. Die physiologischen Maßen replizierten dieses Ergebnis. Jedoch zeigte sich ein anderes Muster f{\"u}r den Affekt beim Konsum von Gewalt in den Medien. Personen, die Gewalt in den Medien st{\"a}rker erfreut, zeigen eine Reduktion der Responsivit{\"a}t gegen{\"u}ber Gewalt auf allen vier Maßen. Weiterhin war bei drei dieser vier Maße (selbstberichte Valenz, Aktivit{\"a}t des C. Supercilii und Hautleitreaktion) dieser Zusammenhang auf die gewalthaltigen Bilder beschr{\"a}nkt, mit keinem oder nur einem kleinen Effekt auf die negativen, aber nichtgewalthaltigen Bilder. Das dritte Experiment (N = 73) untersuchte den Affekt w{\"a}hrend die Teilnehmer ein Computerspiel spielten. Das Spiel wurde eigens f{\"u}r dieses Experiment programmiert, sodass einzelne Handlungen im Spiel mit der Aktivit{\"a}t des C. Supercilii, dem Indikator f{\"u}r negativen Affekt, in Bezug gesetzt werden konnten. Die Analyse des C. Supercilii zeigte, dass wiederholtes Durchf{\"u}hren von aggressiven Spielz{\"u}gen zu einem R{\"u}ckgang von negativen Affekt f{\"u}hrte, der die aggressiven Spielhandlungen begleitete. Der negative Affekt w{\"a}hrend gewalthaltiger Spielz{\"u}ge wiederum sagte die affektive Reaktion gegen{\"u}ber Darstellungen von gewalthaltigen Bildern vorher, nicht jedoch gegen{\"u}ber den negativen Bildern. Das vierte Experiment (N = 77) untersuchte kognitive Desensibilisierung, die die Entwicklung von Verkn{\"u}pfungen zwischen neutralen und aggressiven Kognitionen beinhaltete. Die Teilnehmer spielten einen Ego-Shooter entweder auf einem Schiff- oder einem Stadtlevel. Die Beziehung zwischen den neutralen Konstrukten (Schiff/Stadt) und den aggressiven Kognitionen wurde mit einer lexikalischen Entscheidungsaufgabe gemessen. Das Spielen im Schiff-/Stadt-Level f{\"u}hrte zu einer k{\"u}rzen Reaktionszeit f{\"u}r aggressive W{\"o}rter, wenn sie einem Schiff- bzw. Stadtprime folgten. Dies zeigte, dass die im Spiel enthaltenen neutralen Konzepte mit aggressiven Knoten verkn{\"u}pft werden. Die Ergebnisse dieser vier Experimente wurden diskutiert im Rahmen eines lerntheoretischen Ansatzes um Desensibilisierung zu konzeptualisieren.},

This experiment examined the hypothesis that neutral contextual features of a virtual environment become associated with aggressive meaning and acquire the function of primes for aggressive cognitions. Seventy-six participants were assigned to one of two violent video game conditions that varied in context (ship vs. city environment) or a control condition. Afterwards, they completed a Lexical Decision Task to measure the accessibility of aggressive cognitions in which they were primed either with ship-related or city-related words. As predicted, participants who had played the violent game in the ship environment had shorter reaction times for aggressive words following the ship primes than the city primes, whereas participants in the city condition responded faster to the aggressive words following the city primes compared to the ship primes. No parallel effect was observed for the non-aggressive targets. The findings indicate that the associations between violent and neutral cognitions learned during violent game play facilitate the accessibility of aggressive cognitions.},

  abstract  = {This article investigated how the development of deviant behavior in adolescence is influenced by the variability of deviant behavior in the peer group. Based on the social information-processing (SIP) model, we predicted that peer groups with a low variability of deviant behavior (providing normative information that is easy to process) should have a main effect on the development of adolescents' deviant behavior over time, whereas peer groups in which deviant behavior is more variable (i.e., more difficult to process) should primarily impact the deviant behavior of initially nondeviant classroom members. These hypotheses were largely supported in a multilevel analysis using self-reports of deviant behavior in a sample of 16,891 adolescents in 1,308 classes assessed at two data waves about 1-year apart. The results demonstrate the advantages of studying cross-level interactions to clarify the impact of the peer environment on the development of deviant behavior in adolescence.},

  abstract  = {Peer groups are critical socialization agents for the development of social behavior in adolescence, but studies examining peer-group effects on individuals' prosocial behavior are scarce. Using a two-wave, multilevel data set (N = 16,893, 8481 male; 8412 female; mean age at Time 1: 14.0 years) from 1308 classes in 252 secondary schools in Germany, main effects of the classroom level of prosocial behavior, cross-level interactions between the classroom and the individual levels of prosocial behavior at Time 1, and the moderating role of gender were examined. The results showed that adolescents in classrooms with high collective levels of prosocial behavior at Time 1 reported more prosocial behavior at Time 2, about two years later, reflecting a class-level main effect. A significant cross-level interaction indicated that a high classroom level of prosocial behavior particularly affected individuals with lower levels of prosocial behavior at Time 1. The influence of same-gender peers was larger compared with opposite-gender peers. The findings are discussed with respect to social learning mechanisms in the development of prosocial behavior and their implications for interventions to promote prosocial behavior.},

Methodik: Suizidberichte aus f{\"u}nf großen deutschsprachigen Jugendmagazinen wurden mithilfe qualitativer Inhaltsanalyse im Hinblick auf Geschlecht, dargestellte Motive, Suizid(versuchs)methoden, positive und negative Darstellungsweisen, Schuldzuweisungen und Abweichungen von Medienempfehlungen zur Berichterstattung {\"u}ber Suizid analysiert. Die Suizidzahlen 2 Wochen vor und nach dem Erscheinen von Suizidberichten wurden verglichen. Ergebnisse: 59 Berichte wurden identifiziert. Die h{\"a}ufigste Berichterstattung zum Thema Suizid fand sich in der Zeitschrift Bravo, wobei es zu einer leichten {\"U}berrepr{\"a}sentation weiblicher Suizide und insgesamt zu einer Unterrepr{\"a}sentation von Suizidversuchen kam.

  abstract  = {Exposure to peer aggression is a major risk factor for the development of aggressive behavior in childhood and adolescence. Furthermore, peer aggression has the propensity to spread and affect individuals who were not exposed to the original source of aggression. The aim of this paper is to demonstrate that peer aggression is in many regards similar to a contagious disease. By presenting a program of research based on longitudinal and multilevel studies, we provide evidence for the contagious quality of aggressive behavior, show that individuals vary in their susceptibility to peer aggression, and describe group-level characteristics that moderate the influence of peer aggression. We discuss mechanisms that may explain how individuals catch aggressive behavior from their peers and how the effects on the development of individuals' aggressive behavior unfold over time. Further, we examine processes that may increase the risk of being exposed to peers' aggressive behavior. We conclude with discussing implications for future studies on the contagious nature of peer aggression.},

Whereas past research has focused on social reinforcement mechanisms as the underlying processes, the present longitudinal study analysed the role of external control beliefs as an additional mediator explaining the link between peers' acceptance of aggression and the development of aggressive behaviour. Drawing on a large community sample of N = 1,466 male and female children and adolescents from Germany aged between 10 and 18 years, results of latent structural equation modeling were consistent with the hypotheses that peer acceptance of aggression would predict external control beliefs in the social domain, which in turn, should predict aggressive behaviour over time. Additional multigroup analyses showed that the predicted pathways were consistent across gender and age groups.},

Participants, whose mean age was 13 years at T1, completed self-report measures of physically and relationally aggressive behavior and indicated their normative approval of both forms of aggression at four data waves separated by 12-month intervals. Boys scored higher than did girls on both forms of aggression, but the gender difference was more pronounced for physical aggression. Physical aggression decreased and relational aggression increased over the four data waves in both gender groups. The normative acceptance of both forms of aggression decreased over time, with a greater decrease for the approval of physical aggression. In both gender groups, normative approval of relational aggression prospectively predicted relational aggression across all data waves, and the normative approval of physical aggression predicted physically aggressive behavior at the second and third data waves. A reciprocal reinforcement of aggressive norms and behavior was found for both forms of aggression. The findings are discussed as supporting a social information processing perspective on developmental patterns of change in physical and relational aggression in adolescence.},

  abstract  = {Objective: This study examined the sustained efficacy of a media violence intervention in reducing media violence use, normative acceptance of aggression, and aggressive behavior in adolescents. It used an experimental design to evaluate the effects of the intervention over a period of 30 months. Method: N = 627 German 7th and 8th graders were assigned to a 5-week school-based intervention to reduce media violence use or to a no-intervention control group. Media violence use, normative acceptance of aggression, and aggressive behavior were measured 3 months before the intervention (T1), 7 months post intervention (T2), and at 2 follow-ups 18 (T3) and 30 (T4) months after the intervention. This article focuses on the findings from the 2 follow-ups. Results: Controlling for baseline levels and various demographic covariates, media violence use at T2, T3, and T4 and self-reported physical aggression at T3 were significantly lower in the intervention group, and the indirect path from the intervention to T3 aggression via T2 media violence use was significant. Lower T2 media violence use predicted lower T3 normative acceptance of aggression among participants with lower initial aggression. No effects on nonviolent media use and relational aggression were observed. Conclusion: The findings show that a short class-based intervention can produce lasting changes in media violence use that are linked to a decrease in aggression.},

  abstract  = {Several longitudinal studies and meta-analytic reviews have demonstrated that exposure to violent media is linked to aggression over time. However, evidence on effective interventions to reduce the use of violent media and promote critical viewing skills is limited. The current study examined the efficacy of an intervention designed to reduce the use of media violence and aggression in adolescence, covering a total period of about 12 months. A sample of 683 7th and 8th graders in Germany (50.1\% girls) were assigned to two conditions: a 5-week intervention and a no-intervention control group. Measures of exposure to media violence and aggressive behavior were obtained about 3 months prior to the intervention (T1) and about 7 months post-intervention (T2). The intervention group showed a significantly larger decrease in the use of violent media from T1 to T2 than the control group. Participants in the intervention group also scored significantly lower on self-reported aggressive behavior (physical aggression and relational aggression) at T2 than those in the control group, but the effect was limited to those with high levels of initial aggression. This effect was mediated by an intervention-induced decrease in the normative acceptance of aggression. No gender differences in program efficacy were found. The results show that a 5-week school-based intervention can produce changes in the use of media violence, aggressive norms, and behaviors sustained over several months.},

The adolescents in the two groups, who were in grades 7 and 8 at T1, were matched by gender, age, type of school, and academic achievement. Students in the migrant group reported higher consumption of violent media. At T3, they showed more physical but less relational aggression than their peers of German background. Cross-lagged panel analyses showed parallel associations between media violence use and aggression in both groups: Media violence consumption at T1 and T2 predicted physical aggression at T2 and T3 independent of ethnic background. The reverse path from physical aggression to media violence consumption was nonsignificant. No link was found between media violence use and relational aggression over time.},

Structural equation modeling revealed that SII use was associated with body image concerns for boys and girls via different routes. Specifically, female SII use was indirectly associated with higher body surveillance via thin-ideal internalization and subsequent valuing appearance over competence for girls. For both girls and boys, male SII use was indirectly linked to higher body surveillance via muscular-ideal internalization.

A sample of 660 German adolescents (327 female, 333 male;M-age = 15.09 years) participated in two waves with an interval of 6 months. A structural equation model showed that SVG and SII use at Time 1 predicted body surveillance indirectly via valuing appearance over competence at Time 2. Furthermore, SVG and SII use indirectly predicted both thin- and muscular-ideal internalization through appearance comparisons at Time 1. In turn, thin-ideal internalization at Time 1 predicted body surveillance indirectly via valuing appearance over competence at Time 2. The results indicate that sexualization in video games and on Instagram can play an important role in increasing body image concerns among adolescents. We discuss the findings with respect to objectification theory and the predictive value of including appearance comparisons in models explaining the relation between sexualized media and self-objectification.},

  abstract  = {Public Policy Relevance Statement TV is full of content presenting women in a sexualized way, with a focus on their sexual appearance and appeal to others. We found that across an age spectrum from 15 to 72 years, the more women watched sexualized TV, the more concerned they were about their body; a link between watching sexualized TV and considering cosmetic surgery was found only for women above the age of 31. Adding to the evidence documenting negative consequences of sexualized media use on young women's body image, this study is a first indicator that these might also apply to women across a broader age spectrum. <br /> Extensive research has documented links between sexualized media use and body image concerns. Previous findings are based largely on female adolescents or young adults, although objectification theory predicts changes of body image concerns with age. Therefore, the current study investigated the link of sexualized TV exposure (STE) with self-objectification and consideration of cosmetic surgery within the framework of objectification theory in a sample of 519 female participants between the age of 15 and 72 (M = 39.43 years). Participants completed measures of STE, appearance-ideal internalization, valuing appearance over competence, body surveillance, and consideration of cosmetic surgery. Structural equation modeling revealed that STE was indirectly linked with consideration of cosmetic surgery via valuing appearance over competence and body surveillance. Age was negatively related to internalization, valuing appearance over competence, and body surveillance, but did not moderate the links between STE and body image. Older women scored lower on the body-related variables, but the associations between STE and self-objectification were the same across the age spectrum. STE predicted consideration of cosmetic surgery only for women over 31 years of age. Implications concerning the role of age in linking sexualized media to self-objectification are discussed.},

  abstract  = {Female role models in video games are rare, and if they are present, they are often heavily sexualized. Objectification theory suggests that exposure to sexualized media characters increases self-objectification and decreases body satisfaction in female users. This study investigated the effect of playing a video game with a sexualized versus a nonsexualized character on women's experiences of self-objectification and body satisfaction. We further studied the effect of character personalization as a core feature of video games on the relation between sexualized avatars, self-objectification and body satisfaction. N = 262 female participants reported state self-objectification and body satisfaction after 30 min of playing the video game The Sims 4 with a sexualized or nonsexualized avatar that was either generic or personalized to look like the participant. We predicted that controlling for trait self-objectification, playing the game with a sexualized character would increase state self-objectification, especially in the personalized condition. Regarding the effect of character sexualization on body satisfaction, competing hypotheses based on priming vs. the Proteus effect were tested, considering character personalization and enjoyment of sexualization as moderators and controlling for trait body satisfaction. The current study did not find evidence for the proposed hypotheses. The findings are discussed in terms of the relevance of objectification theory in explaining effects of sexualized models in interactive media.},

Latent Profile Analyses and Latent Transition Analyses yielded four main findings: A three-type solution provided the best fit to the data: an asymptomatic type (i.e., low problem scores in all three domains), a depressed type (i.e., high scores in depression), an aggressive type (i.e., high scores in aggression). Profile types were invariant over the two data waves but differed between girls and boys, revealing gender specific patterns of comorbidity. Stabilities over time were high for the asymptomatic type and for types that represented problems in one domain, but moderate for comorbid types. Differences in demographic variables (i.e., age, socio-economic status) and individual characteristics (i.e., self-esteem, dysfunctional cognitions, cognitive capabilities) predicted profile type memberships and longitudinal transitions between types.},
