Problem: Summarize the following results for an article critque: Most participants had no involvement with bullying situations (74.2%); 10.3% of the students had practiced bullying and 10.1% had suffered bullying, while 5.4% had practiced and suffered some violence, according to the data collected using the "Peer Victimization and Aggression Scale" and the K-means clustering cluster analysis. A greater number of boys had been aggressor (7.4%) and victim aggressor (3.9%) compared to girls, while a greater number of girls had been victim (5.2%) compared to boys. Younger students attending the first grades of elementary school and the first year of junior high school were more vulnerable to victimization. Through logistic regression tests it was found that students not involved with bullying situations enjoyed better family interactions quality (p = 0.00) when compared to aggressors, victims and victim-aggressors. Aggressors, victims and victims-aggressors had had more experiences in terms of physical punishment, negative communication and negative marital climate in their families. The dimension of quality of family interaction "rules and monitoring" (OR: 1.21; p = 0.01) had protective power, as the increase in their score reduced the possibility of qualification in one of the groups involved with bullying situations. On the other hand, the dimensions "physical punishment" (OR: 0.84; p = 0.01) and "negative communication" (OR: 0.53; p = 0.00) increased vulnerability conditions. Need Assignment Help?
