Peer Attachment and Cyber Aggression Involvement among Chinese, Indian, and Japanese Adolescents

Significant advancements have been made in cyber aggression literature, with many studies revealing the consequences associated with adolescents' involvement in these behaviors. Few studies have focused on cyber aggression involvement in China, India, and Japan. The present study examined differences in cyber aggression perpetration and victimization among 1637 adolescents living in China, India, and Japan, while controlling for face-to-face bullying involvement, individualism, and collectivism. Another aim of the present study was to examine country of origin and cyber aggression involvement (i.e., the uninvolved, cyberaggressor-cybervictims, cyberaggressors, and cybervictims) differences in peer attachment. Findings revealed that adolescents from India had the highest levels of cyber aggression involvement when compared to adolescents from China or Japan. Chinese adolescents engaged in more cyber aggression perpetration and were victimized more by cyber aggression when compared to Japanese adolescents. No country of origin differences were found for peer attachment. However, uninvolved adolescents reported higher levels of peer attachment when compared to the other groups. Cyberaggressor-cybervictims had the lowest levels of peer attachment, followed by cybervictims and 340 cyberaggressors. These results suggest that there should be concern about cyber aggression involvement among adolescents in these countries, especially in India, where cyber aggression research has been slow to develop.


Introduction
Most adolescents have spent their lives completely enmeshed in a digital world, with various opportunities and information at their fingertips.Technology usage has many benefits for adolescents, allowing them to quickly communicate with friends and family and to access a wealth of information quickly.Despite such benefits, adolescents also experience risks associated with their technology usage.Cyber aggression is one risk, and it has received attention from researchers, educators, parents, and the general public.Research on cyber aggression is increasing, but research focused on these behaviors in other countries has been slower to develop, particularly in China, India, and Japan.Although the literature has been advancing on cyber aggression, moving from frequency rates to the behavioral characteristics and consequences, little attention has been given to the role of peer relationships in these behaviors.Of this literature, research indicates that perpetrators of cyber aggression are often peers at adolescents' schools and that peer rejection is related to cyber aggression, perpetration, and victimization [1,2].Furthermore, poor peer attachment is related positively to cyber aggression involvement.However, little attention has been given to examining country of origin and cyber aggression involvement differences in peer attachment.To address this gap in the literature, the present study examined differences in cyber aggression perpetration and victimization among Chinese, Indian, and Japanese adolescents as well as the roles of country of origin and cyber aggression involvement in adolescents' perceptions of their peer attachment.

Cyber Aggression Involvement and Culture
This study utilizes the terminology of cyber aggression, which is a broader form of cyberbullying.Cyber aggression includes intentionally harmful behaviors, such as hacking someone's online accounts, sending degrading messages, spreading rumors, and calling others mean names [3].These behaviors are directed toward others who find such behaviors offensive and unwanted, and such behaviors can occur through email, chat programs, text messages, gaming consoles, social networking sites, blogs, and discussion boards.Unlike cyberbullying, Grigg [3] argues that aggressive cyber behaviors do not always include repetition.This component is central to the traditional bullying and cyberbullying definitions.Therefore, measures of cyberbullying focus on repetition while cyber aggression measures do not include the repetition component.This literature review uses both terminologies in order to accurately describe the terminology and methodology of the studies.In addition, cyber aggressive behaviors also include those behaviors that do not have a face-to-face equivalent, like hacking someone's Facebook account.Hacking, as a form of cyber aggression, is carried out with malicious intent, with the desire to damage someone's reputation and/or their relationships.
Cyber aggression and cyberbullying research is even more important as research indicates that this phenomenon is not only found in one country, though much of the research has been conducted in the United States.The available research suggests that cyber aggression is a global concern.Of these studies, researchers have identified cyber aggression and cyberbullying involvement in Australia [12], Belgian [18], Germany [19], Ireland [20], Italy [21], Spain [22], Sweden [23,24], and Turkey [25].
Research on cyber aggression and cyberbullying involvement has been slower to develop in Asia, with findings revealing that perpetration and victimization occurs in China [26], Korea [27], Singapore [28], and Taiwan [16].Examining cyber aggression involvement in Asia is imperative as the top four countries according to internet usage include China, India, and Japan, as well as the United States [29].China ranks as number one, followed by the United States, India, and Japan.Understanding where a country ranks in terms of internet usage is important as access to the internet and the more time spent online are both risk factors associated with cyberbullying perpetration and victimization [30,31].
Given the high levels of internet consumption in China, India, and Japan, more research attention should focus on adolescents' involvement in cyber aggression in these countries.Although some research has examined cyberbullying involvement in China, this research has focused on frequency rates, demographic variables, and lower academic achievement as factors linked to the perpetration of these behaviors [26,32].Few empirical investigations exist concerning cyberbullying perpetration and victimization in India and Japan.In one study, Japanese adolescents reported cyberbullying, but their levels of involvement were lower than adolescents from the United States and Austria [33,34].Studies conducted in India focus on cyber gender harassment, a form of cyber harassment involving similar behaviors as cyberbullying, except that this behavior occurs among adults instead of children and adolescents [35].Taken together, research from China, India, and Japan indicate that cyber aggression and cyberbullying occur among adolescents in these countries, and that their high levels of internet consumption warrant further investigation.
Furthermore, cultural values, including collectivism and individualism, impact adolescents' involvement in aggressive behaviors [36][37][38][39].Collectivistic countries, like China and Japan, promote, prime, and reinforce individuals for behaving consistently with an interdependent self-construal [40].Individualistic countries, like the United States, reinforce independent self-construal.India is considered both a collectivistic and an individualistic country, which might place these adolescents at an elevated risk of cyber aggression involvement when compared to adolescents from China and Japan.In the literature, collectivism is related negatively to aggression involvement, while individualism is associated positively with aggression perpetration and victimization [34,40].Few studies have examined whether cultural values influence adolescents' perpetration and victimization by cyber aggression.Barlett and colleagues [33] examined interdependent self-construal as a moderator in the relationship between country of origin (i.e., United States, Japan) and cyberbullying perpetration.The results revealed that cyberbullying was highest for young adults from the United States when they endorsed low levels of interdependent self-construal.These results were not found for Japanese young adults.However, it isn't clear whether independent self-construal would impact cyber aggression perpetration.Based on the previous research on face-to-face aggression perpetration, it might be likely that independent self-construal increases the risk of engaging in cyber aggression [34,40].
Gender differences in cyber aggression involvement in the United States and in European countries are mixed [2,9,[41][42][43].The literature on gender differences in cyber aggression perpetration and victimization is not as mixed in Asian countries.In this research, Chinese boys perpetrate and are victimized by cyberbullying more often than Chinese girls [26,32,44].Similar patterns were found in Japan as well, with Japanese young adult males perpetrating these behaviors at higher rates than Japanese young adult females [33].It is unclear whether Japanese males would experience more or less victimization than Japanese females as there has been no research conducted on this topic.In addition, research has not been conducted on gender differences in cyber aggression involvement among Indian adolescents.Given that research on cyber gender harassment conducted in India focuses solely on men harassing women through digital technologies, it might be likely that girls are more at risk for cyber victimization while boys might perpetrate cyber aggression more often than girls [35].

Peer Attachment and Aggression
High peer attachment involves adolescents' internationalization of the knowledge that their peers will be available and responsive when needed [36].Problems within peer relationships can place adolescents at a higher risk of being involved in conflicts with their peers [37].Thus, it is not surprising that adolescents with higher rates of victimization and those with behavioral problems are likely to rate their peer relationships as poor, due to these adolescents being less socially integrated in the peer group [45,46].These adolescents also show less empathy toward their peers and this lack of empathy combined with behavioral problems might exacerbate their aggression directed toward their peers.Furthermore, social integration is directly related to adolescents' peer relationships, and when such integration is low, these adolescents are unable to manage and deal with relationships effectively [46].When ostracized by the peer group, adolescents often act reactively by using aggression, developing favorable attitudes toward these behaviors [47].In the literature, higher peer attachment relates to more sympathetic attitudes toward peers, and less delinquency and aggressive behaviors [48].Peer attachment is also related negatively to face-to-face bullying and cyberbullying as well as victimization by both types of bullying.Some attention has focused on the relationship between peer attachment and cyberbullying categories.One of the few studies conducted on these associations found that cyberbullycybervictims have lower levels of peer attachment than uninvolved adolescents [49].No other research exists concerning differences in peer attachment among cyberbullies and cybervictims.Gender has also been investigated as a factor relating to peer attachment.Research suggests that girls are more attached to their peers than boys, though it isn't clear how cyber aggression classification type might alter these associations [50].
Little attention has been given to examining peer attachment among adolescents in China, India, and Japan.The literature suggests that members of collectivistic cultures are attached to their peers, due to the reinforcement of interdependence and maintaining relationships with others in their society [51].Therefore, considering that countries, like China, India, and Japan, have collectivistic focuses, it is likely that these adolescents are also attached to their peers.Given that individualism is endorsed in India as well, these adolescents might experience different levels of peer attachment than adolescents from China and Japan.In the literature, adolescents from the United States had higher levels of peer attachment than adolescents from India [52].On the other hand, other research indicates that Chinese adolescents who immigrated to Italy have higher rates of peer attachment than Italian adolescents [53].Considering these contrasting findings, it is difficult to conclude whether Indian adolescents experience higher or lower levels of peer attachment when compared to adolescents from China and India.In one of the few studies to investigate peer attachment in relation to aggression, Yang and colleagues [54] found that poor peer attachment related positively to Chinese adolescents' aggression and delinquency.These patterns are similar to those found in the United States, though it isn't clear whether similar patterns would be found in India and Japan.In addition, there is no literature revealing the role of cyber aggression categories (i.e., the uninvolved, cybervictims, cyberaggressors, cyberaggressors-cybervictims) and country of origin in adolescents' attachment to their peers.

Present Study
Few investigations have been conducted on cyber aggression involvement among adolescents in China, India, and Japan, especially studies conducted to compare rates across these countries.In addition, it is unknown whether peer attachment relates to cyber aggression perpetration and victimization.To this end, the first aim of the present study compared rates of cyber aggression involvement in China, India, and Japan, while controlling for face-to-face bullying perpetration and victimization, individualism, and collectivism.It was hypothesized that Indian adolescents would report higher levels of cyber aggression involvement when compared to Chinese and Japanese adolescents, given the emphasis on both collectivism and individualism in India [35].Although China and Japan are both collectivistic societies, China is a little less collectivistic and has higher rates of internet consumption, which might contribute to adolescents in this country being more at risk for cyber aggression involvement [29].Therefore, it was hypothesized that Chinese adolescents would report higher levels of cyber aggression involvement than Japanese adolescents.Another aim was to examine the role of gender in adolescents' cyber aggression perpetration and victimization based on country of origin.Chinese and Japanese boys were expected to engage in more cyber aggression perpetrators than girls from these countries.In addition, Chinese boys were also expected to experience more cyber victimization when compared to Chinese girls.Due to the research on cyber gender harassment in India, it was expected the girls would experience more cyber victimization, whereas boys would be more likely to be the perpetrators of cyber aggression [35].
The second aim of the present study was to examine differences in cyber aggression involvement categories (i.e., the uninvolved, cybervictims, cyberaggressors, cyberaggressors-cybervictims) for peer attachment among Chinese, Indian, and Japanese adolescents.Therefore, three-way interactions were examined among gender, country of origin, and cyber aggression involvement.Since Indian adolescents were hypothesized to have higher levels of cyber aggression involvement, it was also hypothesized that cyberaggressors-cybervictims from India would have the lowest levels of peer attachment when compared to cyberaggressors-cybervictims from China and Japan.Uninvolved adolescents were expected to have the highest peer attachment, despite their country of origin.No other hypotheses were made regarding the interaction of cyber aggression involvement classifications and gender.

Participants
Participants were 1637 adolescents (age range 11-15 years old; 48.3% girls) from China (n = 683; 46.7% girls), India (n = 480; 46.5% girls), and Japan (n = 474; 52.6% girls).In China, data was collected from two schools, with one located in Beijing and the other in the An Hui Province.Adolescents from India were from six schools in the Karnataka state of India.Japanese adolescents were recruited from two schools located in a suburb of Tokyo.All data was collected in the Fall of 2013, except for Japanese adolescents.Japanese schools begin in April, and data was collected in July 2014.

Procedures and Measures
Emails were sent to principals from target schools, describing the purpose of the study, how the school could participate, and what adolescents would be expected to do.When principals expressed an interest in the study, a meeting was setup with principals and teachers in order to receive their permission for their students to participate in the study.All principals and teachers agreed to allow students to participant in the study.Consent documents were sent home with adolescents, and then returned to their teachers, except in Japan where consent was obtained from school principals only.On the day of data collection, adolescents provided their assent to participate in the study before completing the surveys.No adolescents refused to participate.This study is part of a larger study on the psychosocial development of adolescents from various countries around the world, with a major focus on understanding the contextual factors which influence their involvement in cyber aggression.For this study, the following questionnaires were administered, including individualism and collectivism, face-to-face aggression involvement, cyber aggression involvement, and peer attachment.All consent, assent, and questionnaires were translated into the primary language of adolescents' country of origin, and then back-translated by researchers fluent in both English and the language of the country of origin.

Individualism and Collectivism
This questionnaire assessed adolescents' endorsement of individualism and collectivism [55].Li and colleagues [55] adapted the Horizontal and Vertical Individualism and Collectivism measure [56] by changing some items to be suitable for adolescents (e.g., "It is important that I do my work better than others" was changed to "It is important that I do my schoolwork better than others").There were sixteen items included in this measure, with eight for individualism (e.g., Winning is everything) and eight for collectivism (e.g., Family members should stick together, no matter what sacrifices are required).Participants rated the items on a scale of 1 (Absolutely disagree) to 9 (Absolutely agree).Both subscales demonstrated adequate reliability (α = 0.92 for individualism; α = 0.79 for collectivism).

Face-to-Face Aggression Involvement
To examine face-to-face aggression involvement, adolescents completed a questionnaire concerning how often they perpetrated face-to-face aggression (e.g., How often do you tell a peer that you will not like him or her unless he or she does what you want?) and were victimized by face-to-face aggression (e.g., How often does a peer say they won't like you unless you do what he or she wants you to do?) [57].The items were described as occurring within the current school year.Adolescents rated the eighteen items (nine per subscale) on a scale of 1 (Never) to 5 (All of the Time).Face-to-face aggression perpetration had a Cronbach's alpha of 0.79 and 0.81 for face-to-face victimization.

Cyber Aggression Involvement
Adolescents indicated how often they perpetrated cyber aggression (e.g., How often do you spread bad rumors about another peer online or through text messages?)and were victimized by cyber aggression (e.g., How often does a peer spread bad rumors about you online or through text messages?)[11].Eighteen items were included on this measure, with nine items per subscale.The items were described as occurring within the current school year.They rated all items on a scale of 1 (Never) to 5 (All of the Time).Cronbach's alphas were acceptable for both cyber aggression perpetration (α = 0.90) and cyber aggression involvement (α = 0.90).

Peer Attachment
The peer attachment subscale of the Inventory of Parent and Peer attachment was used to assess adolescents' perceptions of the positive and negative dimensions of their relationship with their peers [58].There were 25 items used, each rated on a scale of 1 (Almost Never or Never True) to 5 (Almost Always or Always True).Cronbach's alpha was 0.89 for this measure.

Results
To examine the hypotheses for this study, two separate sets of analyses were performed.The first analysis examined differences among adolescents from the three countries regarding their cyber aggression perpetration and victimization.The second analysis investigated the role of cyber aggression involvement in peer attachment, and the differences across the three countries.Bonferroni corrections were utilized for all post-hoc follow-up analyses.Multi-group factor analysis was performed in Mplus for all four measures.Measurement invariance was not found among any of the groups.In addition, the MANOVAs and ANOVAs were performed without the cultural values, but the models with cultural values were better.Therefore, the models included cultural values.Interested readers should contact the first author for more information about these additional analyses.

Peer Attachment and Cyber Aggression Involvement
Before conducting the analysis, adolescents were split into the following groups based on the means of cyber aggression perpetration (M = 1.51,SD = 0.66) and cyber aggression victimization (M = 1.56,SD = 0.75).The following is the breakdown of the groups: cyberaggressors-cyber victims (Group 1; n = 433), cyberaggressors (Group 2; n = 127), cybervictims (Group 3; n = 150), and the uninvolved (Group 4; n = 866).An ANOVA was conducted with parental attachment as the dependent variable, and country, gender, and group as the independent variables.Face-to-face aggression involvement, individualism, and collectivism were included as covariates.Three two-way interactions were included between country and groups, country and gender, and gender and groups.A three-way interaction was also included among country, gender, and groups.Main effects of gender (F(1, 1565) = 32.82,p < 0.001) and groups (F(3, 1565) = 14.78, p < 0.001) were found.The main effect of country and the interactions were not significant.Girls (M = 3.78, SD = 0.04) reported more peer attachment when compared to boys (M = 3.45, SD = 0.04).Uninvolved adolescents (M = 3.88, SD = 0.03) had greater peer attachment when compared to the other groups (cyberaggressors-cybervictims: M = 3.30, SD = 0.05; cyberaggressors: M = 3.69, SD = 0.06; cybervictims: M =3.53, SD = 0.06).Cybervictims had lower levels of peer attachment than cyberaggressors and uninvolved adolescents.Cyberaggressors-cybervictims had the lowest peer attachment when compared to cybervictims, cyberaggressors, and uninvolved adolescents.

Discussion
The purposes of this study were twofold.The first aim was to investigate the conjoint influence of country of origin and gender on cyber aggression involvement among Chinese, Indian, and Japanese adolescents.The second aim was to examine the combined effects of country of origin, gender, and the cyber aggression involvement classifications on peer attachment.Results from the present study provide further evidence that cyber aggression is an issue impacting adolescents across the world.The findings of the present study contribute greatly to the body of literature on cyber aggression involvement because cultural values and face-to-face aggression involvement were included as covariates.
Providing support for one of the study's hypotheses, Indian adolescents reported greater cyber aggression perpetration and victimization than adolescents from either China or Japan.Such findings might be supported by the literature, suggesting that Indian culture promotes and rewards both individualistic and collectivistic behaviors [40].Given their stronger tendency toward individualism than adolescents in China or Japan, adolescents from India might be more at risk for cyber aggression involvement, which is further supported from the literature linking more face-to-face bullying and victimization among adolescents from individualistic countries (e.g., the United States) than collectivistic countries (e.g., China, Japan) [37][38][39].Furthermore, Chinese adolescents reported higher cyber aggression involvement when compared to Japanese adolescents, which supported the study's hypotheses.This finding is difficult to reconcile with the literature, considering that both countries highly value collectivism and that collectivism is usually associated with less bullying involvement [40].Another possibility is that China's greater internet consumption might indicate that Chinese adolescents also spend more time using the internet than Japanese adolescents.Access to the internet and frequency of usage is a risk factor associated with cyber aggression involvement, which might indicate that Chinese adolescents are more at risk than Japanese adolescents [30,31].Such findings are also aligned with other work in Japan, revealing that Japanese adolescents rarely reported being involved in cyberbullying [34].
Understanding cyber aggression involvement in Asia is better understood by focusing on country of origin and gender differences, which reveal complex patterns.The significant two-way interaction between country of origin and gender suggests that boys reported more cyber aggression involvement in China and India than girls in these countries.Finding that Chinese boys perpetrated and were victimized by cyber aggression more often than Chinese girls is consistent with the literature on gender differences in Chinese adolescents' involvement in cyberbullying [26,32,39].The findings from India are difficult to compare with the literature since no research has been conducted on cyber aggression involvement in this country.No gender differences were found for cyber aggression perpetration and victimization among Japanese adolescents.This result is not consistent with the literature.For instance, Barlett et al. [33] found that Japanese males had higher levels of cyberbullying perpetration than Japanese females.One possibility for this inconsistent finding is that Barlett and colleagues' study included young adults, whereas the present study included adolescents.Such differences might reflect developmental differences in the samples.
Concerning peer attachment, country of origin was not significant.Thus, adolescents in China, India, and Japan did not differ in their levels of peer attachment.Such findings might reflect the focus on collectivistic values within their countries, which emphasize interdependence and possibly positive peer relationships [40].Gender was significant, indicating that girls reported more peer attachment when compared to boys, no matter their country of origin.This finding is consistent with a recent meta-analysis on gender differences in peer attachment [50].In addition, uninvolved adolescents reported greater peer attachment when compared to cyberaggressors-cybervictims, cybervictims, and cyberaggressors, which is supported by the literature [53].Furthermore, cyberaggressors-cybervictims had the worst levels of peer attachment when compared to cybervictims and cyberaggressors.The findings regarding cyber aggression involvement supported the study's hypotheses.Unlike Burton and colleagues [53], the present study also found that cybervictims had lower levels of peer attachment than cyberbullies.However, this finding is supported by the literature on face-to-face bullying involvement [59][60][61].The interaction among country of origin, gender, and cyber aggression involvement was not significant.This was not expected since it was hypothesized that Indian adolescents' greater involvement in cyber aggression would worsen their peer attachment.Such a finding might suggest that collectivism serves some type of protective function.In their review of the ecological contexts of bullying, Huang and colleagues [37] suggested that the macrosystem, particularly the emphasis on collectivism versus individualism, might mitigate the negative effects associated with face-to-face bullying involvement among Chinese children and adolescents.

Limitations and Future Directions
Even though the present study provided much needed information concerning cyber aggression perpetration and victimization in China, India, and Japan, there are a few limitations that should be noted and addressed in future research.First, this study relied on self-reports to assess face-to-face and cyber aggression perpetration and victimization.A multiple informant approach is needed in this research as it reduces the biases associated with self-reports.In addition, recent research has demonstrated the strength of utilizing peer-nominations to assess peer-based cyber aggression involvement [2,11].Second, this study utilized a concurrent research design to assess cyber aggression perpetration and victimization.Thus, it is impossible to understand the temporal ordering of peer attachment and cyber aggression involvement, and future research should focus on utilizing longitudinal designs.

Conclusions
The present study provided a much needed examination of the differences in cyber aggression perpetration and victimization among Chinese, Indian, and Japanese adolescents as well as the differences in the cyber aggression involvement classifications for peer attachment.It is also among a few studies to control for face-to-face aggression involvement and cultural values when examining these differences, which is a methodological improvement and an important direction for researchers interested in the role of culture in cyber aggression perpetration and victimization.Despite the differences found in the study, these findings suggest that more research should be conducted on cyber aggression involvement among adolescents in China, India, and Japan.This is incredibly important for cyber aggression perpetration and victimization in India as Indian adolescents had the highest levels of these behaviors and victimization when compared to Chinese and Japanese adolescents.This study may inform school personnel in these countries concerned with identifying risk factors associated with adolescents' cyber aggression involvement based on their gender and their levels of peer attachment.
