Objective: To observe the near-and long-term effects of acceptance and commitment therapy (ACT) on psychological flexibility, self-efficacy, and glycemic control in patients with type 2 diabetes. Methods: A total of 96 patients with type 2 diabetes admitted to Zhuzhou Central Hospital during the period from January to December 2017 were selected as subjects. According to the random number table method, they were divided into the control group and the ACT group, 48 cases in each group. The control group was given regular health education, and the ACT group was given ACT-oriented health education. The psychological flexibility, self-efficacy and glycemic control of the two groups were compared before intervention, 7 weeks after intervention and 1 year after intervention. Results: After 7 weeks of intervention, the psychological flexibility and self-efficacy scores of the ACT group was (21.47±4.89) and (8.96±1.70) respectively, the control group was (25.28±6.33) and (7.80±1.42) respectively. After 1 year of intervention, the psychological flexibility and self-efficacy scores of the ACT group was (23.87±5.03) and (8.09±1.38) respectively, and the control group was (27.19±5.48) and (6.97±1.24) respectively. The ACT group was significantly better than the control group, and the difference was statistically significant (t=-3.300-4.044, P<0.01). After 7 weeks of intervention, the effective rate of blood glucose control in the ACT group was 93.75% (45/48), and the control group was 75.00% (36/48). After 1 year of intervention, the effective rate of blood glucose control in the ACT group was 86.96% (40/46), and the control group was 65.91% (29/44). The ACT group was significantly higher than the control group, and the difference was statistically significant (χ²=6.400, 5.569, P<0.05).

Objective: To explore the prevalence and characteristics of traditional bullying and cyberbullying behavior among primary and middle school students and to provide evidence for the comprehensive intervention. Methods: An anonymous self-administrated questionnaire survey was conducted among 12 417 students (grade 5 to 12) selected with multi-stage cluster random sampling in 16 districts in Beijing between Sept. and Oct. 2017. Descriptive statistics and chi square test were used for statistical analysis. Results: In the past 6 months, 2.6% of students were reported to be involved in traditional bullying,10.6% were reported of being bullied. 1.0% of students were reported to be involved in cyberbullying, and 2.8% reported of being bullied. Boys reported significantly higher rates of traditional bullying and cyberbullying behavior. The reporting rate of traditional bullying and cyberbullying gradually increased with grade. The reporting rate of traditional bullying was highest in junior high school, while cyberbullying was common in both junior and senior high school. Students with low academic performance were more likely to involve in bully as perpetrators in both types(P<0.05). The higher maternal education background was, the higher their children involved in bullying perpetrators(P=0.03). The proportion of students who reported bullied at school was higher than cyberbullying(χ2=15.25, P<0.01). Cyberbullying were more likely to take place outside school compared with traditional bullying(χ2=3.98, 9.76, P<0.05). Compared with traditional bullying, cyberbullying has a higher proportion of various types of bullying or being bullied. Conclusion Bullying is still prevalent among primary and middle school students in Beijing, and cyberbullying is becoming more widespread. Schools, family and the community-based comprehensive prevention strategies should be developed for a safe campus and network environment to prevent traditional and cyberbullying.
