ABSTRACT
Objectives:To explore the relationship between cyber bullying incident and psychological status of college students,and the effects of online social support and psychological resilience.Methods:Totally 608 college students (aged 17-25 years) were selected.They were investigated with the Cyberbullying Inventory (CI,including cyber bullying and cyber bullied),Symptom Checklist 90 (SCL-90),College Students' Online Social Support Scale (CSOSSS) and Connor-Davidson Resilience Scale (CD-RSIC).Results:Online social support partly mediated the relationship between cyber bullying dimension or cyber bullied dimension and psychological status,and the ratios of the mediating effects to total effects were 24.1％ and 22.0％ separately.Psychological resilience didn't moderate the relationship between cyber bullying dimension and psychological status (β =0.01,P ＞ 0.05),but moderated the relationship between cyber bullied and psychological status (β =-0.08,P ＜ 0.05).Conclusion:The cyber bullying and cyber bullied may be not only related to psychological status directly,but also related to social support indirectly through online.Psychological resilience could buffer the effect of cyber bullied on psychological status.
ABSTRACT
Objective To understand the mycoplasma pneumoniae(MP) infection degree in community children by testing specific IgM antibodies against MP in different age bracket group in Shanghai Meilong area. Methods Using random sampling method, blood specimens of 1 817 children from kindergartens and primary or junior high schools in Meilong area were obtained. Children were from 2 to 15 years old, 969 males, 848 females. The specimens were tested for IgM antibodies against MP using with gelatin particle agglutination test. The data were statistically analyzed using with ?2 test. Results Five hundred and fifty-nine (30.7%) IgM antibodies against MP were positive from 1 817 blood specimens. The positive percentages were 27.34% and 34.66% for males and females, which had significant difference(?2=11.383 P=0.001). The higher percentage was detected from kindergarten children than primary and junior high school children(P=0). The positive percentages of anti-mycoplasma IgM had no significant differences between different kindergartens and primary schools(P=0.526,0.232). On the contrary, between different junior high schools, there were siginificant differences (?2=9.825 P=0.002). Conclusions MP is an important pathogenic mycoplasma cause for respiratory tract infections in Meilong area. It is relative to childhood asthma. The prevention and cure of MP infection for children shall be paid more attention.
