ABSTRACT
BackgroundIn public health emergencies， medical staff undertake many important tasks. Having a good mental health status and capability in popularization of science can improve the work efficiency of medical staff， and thus enhancing the public's trust and support for medical care. ObjectiveTo investigated the anxiety， insomnia and security level of medical staff under the public health emergency， and to explore the correlation between anxiety and capability in popularization of science of them. MethodsFrom June 1 to September 1， 2020， a total of 588 medical staff in Sichuan Province were investigated through the Questionnaire Star platform. The survey included a self-designed general information questionnaire， the Psychological Security-Insecurity Questionnaire （S-I）， Self-rating Anxiety Scale （SAS）， Athens Insomnia Scale （AIS） and science popularization questionnaire during the COVID-19 epidemic. Pearson correlation analysis was used to examine the correlation among SAS， S-I and AIS scores， as well as the correlation between SAS and the science popularization questionnaire during the COVID-19 epidemic. ResultsDuring the public health emergency， the S-I score of the medical staff was （27.46±9.20）， with 21 cases （3.57%） having a low level of security. The SAS score was （44.21±9.57）， with 208 cases （35.37%） having anxiety symptoms. The AIS score was （11.40±5.25）， with 450 cases （76.53%） suffering from insomnia. Correlation analysis showed that SAS score was negatively correlated with S-I score （r=-0.640， P<0.01）， while positively correlated with AIS score （r=0.618， P<0.01）. There was a negative correlation between the degree of usage about medical staff's science popularization tool and SAS score （r=-0.501~-0.185， P<0.01）. The use of science popularization channels was negatively correlated with anxiety （r=-0.510~-0.232， P<0.05 or 0.01）. There was a negative correlation between the level of trust to popularization of science and medical staff anxiety （r=-0.548~-0.338， P<0.01）. ConclusionUnder the public health emergency， the detection rates of anxiety symptoms and sleep disorders among medical staff are high， and anxiety is negatively correlated with medical staff's capability in popularization of science. ［Funded by Sichuan Mianyang Psychological Growth Guidance and Research Center for Minors Funded Project （number， SCWCN2020YB11）］.
ABSTRACT
ObjectiveTo explore the application value of event-related potential P300 in the evaluation of cognitive dysfunction in patients with traumatic brain injury. MethodsFrom January to September 2021， a total of 36 patients with traumatic brain injury who were conservatively treated in the Neurosurgery Department of the Third Hospital of Mianyang and met the diagnostic criteria were selected as the experimental group. And 36 participants were recruited from the family members and carers of other patients in the hospital as the control group. Oddball paradigm was used to measure the event-related potential P300. Montreal Cognitive Assessment （MoCA） and Mini-Mental State Examination （MMSE） were used to assess the cognitive function of the subjects. The latency and amplitude of P300， MoCA and MMSE scores were compared between two groups. The detection rates of P300 latency， MoCA and MMSE on cognitive dysfunction in patients with traumatic brain injury were compared. ResultsMoCA and MMSE scores in experimental group were lower than those in control group ［（18.08±4.29） vs. （27.36±1.20）， （22.53±3.54） vs. （28.11±1.09）， t=-12.510， -9.041， P<0.05］. The latency of P300 in experimental group was higher than that in control group ［（406.08±26.95）ms vs. （367.08±22.50）ms， t=6.665， P<0.05］， and the amplitude was lower than that in control group ［（7.76±0.90）μV vs.（9.87±0.99）μV， t=-9.459， P<0.05］. In experimental group， the positive detective rate of P300 latency and MoCA on cognitive dysfunction were higher than that in MMSE （χ2=5.675， 7.604， P<0.05）. ConclusionEvent-related potential P300 can be used as an objective clinical indicator for evaluating cognitive dysfunction in patients with traumatic brain injury.
ABSTRACT
The purpose of this article is to analyze the effectiveness of dialectical behavior therapy （DBT） in adolescent non-suicidal self-injury （NSSI） behavioral therapy， in order to provide a reference for the intervention of NSSI behavior in adolescents in China. NSSI behavior is a common mental health threat for adolescents. In recent years， it has become a mental health problem that cannot be ignored worldwide. At present， psychotherapy is mainly used for NSSI behavior. Increasing evidence shows that DBT is effective in reducing NSSI behavior. This article summarizes the effectiveness of DBT in the treatment of NSSI behavior by describing the risk factors of NSSI behavior， an overview of DBT and the efficacy of DBT in the application of NSSI.
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.
