Table options Frequency of cyber-bullying/victimization behaviors In terms of the specific CB behaviors, results indicated that spreading rumors and malicious comments for a third person through Short Message Service (SMS;M = 1.51, SD = 0.55), was reported most frequently, while using someone else’s mobile phone or computer for masquerading was the least frequent CB behaviors (M = 0.08, SD = 0.31) and (M = 1.15, SD = 0.51) respectively. In terms of CV, the most commonly reported behavior was having something written on the internet about the victim that s/he didn’t want others to see (M = 1.59, SD = 0.89), and the least reported was being ridiculed by having videos and pictures of him/her being forwarded online (M = 1.23, SD = 0.65). It should be noted, however, that although these behaviors were most frequently reported, they were quite rare, since the mean lies between the two least frequent response categories (i.e., “never” and “once or twice”). Participant role classification, internet frequency and use Students were classified into participant roles on the basis of their CB/V total scores. Scores falling in the upper and lower quartiles of the distribution of both CB and CV scores were indicative of high and low CB and CV respectively. Thus, four groups were formed: 34 students (14%) were classified as cyber-bullies (high on CB and low on CV), 27 (11%) as cyber-victims (high on CV and low on CB), 78 (33%) as cyber-bully/victims (high on both CB and CV), and 99 (42%) as uninvolved (low on both CB and CV). Males were more likely to be classified as cyber-bully/victims, whereas females were more likely to be classified as uninvolved, χ2(3) = 11.07, p < .05. A chi-square test examined the relation between Internet use and participant roles and was found significant, with cyber-bully/victims reporting higher Internet use than other groups, χ2(3) = 13.59, p < .05. Cyber-bully/victims also used chat-rooms more frequently, χ2(3) = 16.96, p < .01, as well as Instant Messaging (IM) programs, χ2(3) = 22.27, p < .001, and SNS, χ2(3) = 17.21, p < .01. Group Differences Gender One-way ANOVAs showed that participants’ scores significantly differed in terms of gender, except for hostility, depression, boredom susceptibility, social skills, adventure seeking and social anxiety (Table 3). More specifically, males scored higher than females in CB, experience seeking, grandiose/manipulative, impulsive/irresponsible and callous/unemotional traits. Females, on the other hand, scored higher on cognitive empathy, emotional reactivity and interpersonal sensitivity. It should be noted, that although the ANOVAs showed significant mean gender differences, the effect sizes ranged from small to medium (range: .02 -.16). Table 3.

Table options Participant roles One-way ANOVAs tested whether participant roles had any significant effect on students’ scores on the variables under study (Table 4). In all cases, post hoc multiple comparisons using the Scheffé test were used. Cyber-victims scored significantly higher in emotional reactivity and social skills (both dimensions of empathy) compared to uninvolved and cyber-bully/victims. Cyber-bully/victims achieved greater scores in most of the rest of the variables compared to the other three groups. Specifically, they scored higher in anxiety, interpersonal sensitivity, and disinhibition, than cyber-bullies and uninvolved. They also scored higher compared to cyber-bullies, cyber-victims and uninvolved in depression and impulsive/irresponsible traits. Finally, they reported higher scores in experience seeking, boredom susceptibility, hostility, grandiose/manipulative and callous/unemotional traits, in comparison to cyber-bullies, cyber-victims or uninvolved. It should be noted that effect sizes varied in sizes from small to large (range: .03 - .21). Table 4. Participant Role Differences in CB, CV, Personality Characteristics and Psychological Symptoms.

Table options Correlation Analysis Pearson correlations were computed to assess the relation between CB, CV, and the rest of the variables. Coefficients ranged between .10 and .86, the greatest correlation was between CB and CV, whereas the lowest between hostility and social anxiety, emotional reactivity and disinhibition, and callous/unemotional trait and boredom susceptibility (Table 2). Both CB and CV had medium positive correlations with all psychopathic traits, medium and low positive correlations with psychological symptoms, and social anxiety, and low positive correlations with Internet frequency and use. Regression Analysis Two four-step hierarchical stepwise multiple regressions were run to determine the extent to which CB and CV can be predicted by gender, personality, psychological symptoms, Internet frequency and use. Variable selection was conducted using a combination of theory-based and statistically recommended procedures. Sets of variables were entered into the analysis in a predetermined order informed by their theoretical significance. Thus, Internet frequency and use were entered in the model last (step 4) in order to evaluate their relative contribution once the effects of personality characteristics and psychological problems were accounted for. Since it is assumed that gender, personality (empathy, sensation seeking, psychopathic traits), and psychological symptoms (anxiety, hostility, depression, interpersonal sensitivity, social anxiety) precede communication media use (i.e. Internet), they were entered in the model in three consecutive steps. However, given the concurrent nature of the data, the findings of the regression analyses simply confirm the presence of shared variance among the sets of predictors rather than a meaningful ordering of effects. CB was predicted by impulsive/irresponsible traits, social skills, callous/unemotional traits, depression and Internet use (Table 5). Significant predictors accounted for 32% of the total variance, with impulsive/irresponsible traits explaining the highest percentage (12%). Gender also predicted CB, but it was not significant.
