| ObjectiveTo explore the association among aggressive behavior, self-esteem and cognition ofchildren and adolescents, and to compare the differences of explicit and implicitcognition between aggressive and non-aggressive individuals, so to provide scientificbasis for aggression prevention and treatment.MethodsTwenty-three thousand and ninety-four students were selected from15cities in Anhui,Yunnan, Guangdong, Heilongjiang, Hubei provinces by using multi-stage stratifiedcluster sampling. Aggression and self-esteem were assessed by Buss and Warren’sAggression Questionnaire (BWAQ) and Self-esteem Scale (SES). According to thedistribution of BWAQ score, subjects whose score were at the top of95%wereselected as aggressive group, whose score were below the mean score were qualifiedas a control group, and Implicit Attitude Test (IAT) and Chinese Cognitive AbilityScale (CCAS) were conducted and the differences of explicit and implicit cognitivecharacteristics between two groups were analysed..Results 1ã€Among23904participants, the prevalence rate of aggression was5.20%, and therewere no significance differences on gender and grade (p>0.05).2ã€The characteristics of aggression of child and adolescent included:â‘ on scores ofphysical, verbal, and hostility aggression and the total scores of aggression, boys weresignificantly higher than girls (P<0.05).â‘¡on scores of physical, verbal, anger andhostility aggression and the total scores of aggression, significant grade differenceswere found, and the scores increased by grade increased.â‘¢the influencing factorsof aggression included school and social environment, parents’ education attitudeconsistency, self satisfaction with appearance, parents’ education level, the number offriends, whether the only child or not etc.3ã€The characteristics of self-esteem among child and adolescent included:â‘ theself-esteem scores of boys were significantly higher than that of girls (P<0.05);â‘¡the self-esteem scores of elementary school students were significant higher than thatof junior high school and high school students, however, no significance was foundbetween junior high school and high school students.â‘¢the influencing factors ofself-esteem included whether the only child or not, parents’ education level,relationship with teachers and peers, self satisfaction with appearance and otherdemographic characteristics (P<0.05).4ã€Negative correlation were found between self-esteem and physical, anger, hostilityaggression, and positive correlation was found between self-esteem and verbalaggression(P<0.01), however, no significant correlation was found betweenself-esteem and indirect aggression.5ã€Both in aggression and control group, incompatible coupling were larger thancompatible coupling in Implicit Attitude Test, and the difference was significant(P<0.05).6ã€The differences on space/calculation were significant between aggression andcontrol group (P<0.05), however, no significant was found on other dimensions ofCCAS (P>0.05). 7ã€The aggressive scores were no significant relationship with IAT scores and CCASscores (P>0.05).Conclusion1ã€Gender and grade differences were found both in aggression and self-esteem amongchild and adolescent. Compare to girls, boys were more likely to conduct physical andverbal aggression. The total score of aggression increased by grade increased. Theself-esteem scores of boys were significant higher than that of girls, and theself-esteem scores were decreased by grade increased both in boys and girls.2〠Both of aggression and self-esteem among children and adolescents wereassociated with school and family environment, and peer relationship.3〠The explicit and implicit cognition of aggression were independence amongchildren and adolescents. |
