ABSTRACT
Objective:To explore the mediating role of insomnia between childhood trauma and suicide risk in middle school students.Methods:Childhood trauma questionnaire(CTQ), insomnia severity index(ISI) and suicidal behaviors questionnaire-revised(SBQ-R) were used to investigate 3 442 middle school students.According to the total score of the SBQ-R, those who scored less than or equal to 6 were divided into low suicide risk group, and those who scored more than or equal to 7 were divided into high suicide risk group.In this study, there were 2 168 students in the low suicide risk group and 1 274 students in the high suicide risk group.SPSSAU 21.0 online statistical software was used for common method deviation test, descriptive statistics, variance analysis and correlation analysis, and structural equation model was constructed, and Bootstrap method was used for mediation effect test.Results:(1) There were statistically significant differences between the high suicide risk group and the low suicide risk group in terms of grade and gender( χ2=11.144, 83.737, both P<0.05), and there were statistically significant differences in the types of childhood trauma and the severity of insomnia( χ2=292.211, 333.998, both P<0.05). (2) The total score of childhood trauma in the high suicide risk group (43.92±10.50) was higher than that in the low suicide risk group (37.74±6.93) ( F=351.78, P<0.01), and the score of insomnia in the high suicide risk group (10.66±5.54) was higher than that in the low suicide risk group (7.04±4.76) ( F=379.25, P<0.01). (3)The total score of childhood trauma was positively correlated with the score of suicide risk ( r=0.415, P<0.01), and the total score of childhood trauma was positively correlated with the score of insomnia ( r=0.306, P<0.01), and the score of insomnia was significantly positively correlated with the score of suicide risk ( r=0.399, P<0.01). After controlling for demographic data, anxiety and depression, the correlation was still significant ( P<0.01). (4) Path analysis and mediation test showed that childhood trauma had a positive effect on insomnia ( β=0.30, P<0.01), insomnia had a positive effect on suicide risk ( β=0.29, P<0.01), and childhood trauma had a positive effect on suicide risk ( β=0.33, P<0.01). The mediating effect of insomnia accounted for 21.21% of the total effect.After controlling for demographic data, anxiety and depression, the mediating effect accounted for 10.66% of the total effect. Conclusion:Childhood trauma and insomnia have a significant impact on the suicide risk among middle school students.Insomnia plays a partial mediating role between childhood trauma and middle school students' suicide risk.Timely management of the sleep disturbances of traumatized individuals can reduce the suicide risk among middle school students.

ABSTRACT
ObjectiveTo investigate the mental health condition of college students during the Corona Virus Disease 2019 （COVID-19） ， and to provide accurate basis for their psychological intervention. MethodsThrough the way of electronic questionnaire， questionnaire star as tools， random investigation of college students in a university in Sichuan. Self-rating Anxiety Scale （SAS）， Self-rating Depression Scale （SDS） and Somatization Symptom Scale （SSS） were used to evaluate their anxiety， depression and somatization symptoms. At the same time， a self-made questionnaire was used to investigate their styles of help seeking， and the relationships between them. ResultsA total of 551 valid questionnaires were collected， including 4.90% of anxiety symptoms， 28.68% of depression and 17.97% of somatization symptoms. In terms of somatization， the detection rate was higher in urban college students than those in rural （23.35% vs. 13.27%， P<0.05）， non-medical students was higher than medical students （21.40% vs. 13.89%， P<0.05）. Women's SSS score was higher than men's ［（26.51 ± 5.44） vs. （25.27 ± 5.78）］， urban college students' SSS score were higher than rural ［（26.69 ± 5.98） vs. （25.38 ± 5.12）］， and non-medical students’ SSS score were higher than medical students ［（26.65 ± 5.59） vs. （25.21 ± 5.45）］， and the differences were statistically significant （P<0.05）. Partial correlation analysis showed that SSS score was positively correlated with SAS score （r=0.110， P=0.010） and negatively correlated with SDS score （r=-0.087， P=0.042）. The top three common ways of help-seeking pattern among college students were self-regulation （81.85%）， talking to family or friends （70.78%） and offline psychological counseling （28.31%）. ConclusionUnder the COVID-19 epidemic， the detection rate of depressive symptoms and somatization symptoms of college students is high. The detection rate of somatization symptoms of female， urban and non-medical college students is high. Self-regulation and talking to family or friends are the main psychological styles of help seeking for college students.
ABSTRACT
Objective:To collect and analyze the non-compliance/protocol violation or deviation reported to the hospital Ethics Committee from 2017 to 2019, to explore the pattern of such events, as well as the causes and related logic. Empirical data evidence, lessons learned and preliminary advice were proposed to improve the understandings, management and implementation of clinical trials regarding to the non-compliance/protocol violation or deviations.Methods:The chi-square test and non-parameter test were conducted using SPSS 22.0.A total number of 754 reports received were analyzed, compared and summarized to provide the preliminary advice.Results:From 2017 to 2019, 754 reports on non-compliance/protocol violation or deviation, which covered 219 projects from 29 clinical departments, were received. 88% of these projects were drug/medical device clinical trials, while other 12% were investigator initiated trials. The reportrd events could be divided into 7 categories. The distribution of project resources, trial types and clinical specialties are significantly different. Meanwhile, the reports submitted by investigators have a lot of space for improvement.Conclusions:There were significant differences in the type and number of reported events on non-compliance/protocol violation or deviation between different trial types, as well as clinical trial specialties. The application report of protocol violation is generally poor. Combined with the working practice, the common reasons for the protocol violation are " the low overall compliance of the subjects" and " the insufficient compliance of the researchers" . Preliminary suggestions for management reform, such as increasing the training for researchers, improving the reporting mode, and regularly issuing follow-up and review research reports are recommended.
