BackgroundPatients with schizophrenia and depressive disorders exhibit abnormalities in perceptual processing. Previous perceptual studies are mainly based on asking participants to fill in a questionnaire， and little research has been undertaken on objective behavior in patients with schizophrenia and depressive disorders. ObjectiveTo explore the behavioral changes in vibrotactile sense among patients with schizophrenia and depressive disorders， so as to enrich relevant findings in objective behavioral research. MethodsFrom March 2021 to September 2023， 33 patients with schizophrenia and 31 patients with depressive disorders in the outpatient and inpatient departments of Beijing Huilongguan Hospital and met the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） diagnostic criteria were enrolled. And another 34 healthy controls were concurrently recruited at Beihang University and Beijing Huilongguan Hospital. Patients with schizophrenia were assessed using Positive and Negative Symptom Scale （PANSS）， and patients with depressive disorders were assessed using Hamilton Depression Scale-17 item （HAMD-17）. The vibrotactile sensitivity of the left hand in all participants was tested in a delay match-to-sample procedure， and the correct rate of vibrotactile delayed discrimination task was compared among the three groups. ResultsCompared with healthy controls， a reduction was found in the correct rates at index finger， middle finger and ring finger in patients with schizophrenia （P<0.01）， the average correct rate at five fingers in patients with schizophrenia （P=0.001）， and the correct rate at thumb in patients with depressive disorders （P=0.026）. No statistical difference was reported in correct rate of vibrotactile delayed discrimination task between patients with depression disorders and schizophrenia （P>0.05）. The average correct rate of vibrotactile sense in schizophrenia group was not significantly correlated with the duration of disease， age of onset， chlorpromazine equivalent doses and PANSS score （r=0.058、0.045、0.114、-0.194， P>0.05）. The average correct rate in depressive group was negatively correlated with age of onset （r=-0.415， P=0.020）， but not significantly correlated with the duration of disease and HAMD-17 score （r=-0.044， 0.142， P>0.05）. ConclusionPatients with schizophrenia and depressive disorders have impaired vibrotactile sense. The vibrotactile sense is impaired in index， middle and ring fingers among patients with schizophrenia， and in thumbs of patients with depressive disorders. Moreover， the impairment in patients with depressive disorders may be related to the age of onset. ［Funded by 2023 Hebei Provincial Graduate Innovation Funding Project （number， CXZZSS2023140）］

Objective:To construct an evaluation the index system of entrustable professional activities for resident training doctors in psychiatric department,and to provide reference for formulating training strategies and assessment standards.Entrustable professional activities refers to the ability of trainees to perform and complete spe-cific clinical tasks independently after they have been trusted.Methods:Through documental analysis and semi-structured interviews,the item database of entrustable professional activities for psychiatric resident training physi-cians was established.Delphi consultation was conducted among 63 experts in the field of psychiatry from 7 national resident training bases and 3 medical colleges in China.Indicators were comprehensively screened and sorted out,and indicators at all levels and their weights were determined by the analytic hierarchy process.Results:A hierarchi-cal evaluation index system of entrustable professional activities for psychiatric resident training doctors was con-structed,including 4 first-level indicators,17 second-level indicators and 68 third-level indicators.The weights of the first-level,second-level and third-level indicators were determined.Conclusion:The evaluation index system of en-trustable professional activities is comprehensive and systematic,which is suitable for clinical work and convenient for practical application.It could provide quantitative standards for the assessment of psychiatric residents and pro-mote the improvement of training quality.

BackgroundThe development of executive function in adolescents is influenced by many environmental factors. Previous studies have found that perceived stress is closely related to executive function， whereas its role in the mediation of executive function remains poorly studied. ObjectiveTo explore the role of negative affect and self-hate in mediating the relationship between perceived stress and executive function in adolescents， so as to assist the improvement of executive function in adolescents. MethodsQuestionnaires were administered to 7 734 adolescents from five junior and five senior high schools in Rizhao city， Shandong province from 1 to 30 May 2022. Data were collected using a self-made questionnaire， and adolescents were assessed using Perceived Stress Scale （PSS）， Behavior Rating Inventory of Executive Function-Self Report Version （BRIEF-SR）， Patient Health Questionnaire （PHQ-4） and Self-Hate Scale （SHS）. Spearman correlation analysis was conducted to examine the correlation between variables. A Bootstrap method was chosen to examine the mediation effect of self-hate and negative affect on the relationship between perceived stress and executive function in adolescents. ResultsA total of 7 012 （90.66%） valid questionnaires were retrieved. BRIEF-SR score was positively correlated with PSS， PHQ-4 and SHS scores （r=0.564， 0.653， 0.597， P<0.01）. PSS score was positively correlated with PHQ-4 and SHS scores （r=0.615， 0.531， P<0.01）. PHQ-4 score was positively correlated with SHS score （r=0.566， P<0.01）. The value of mediation effect of perceived stress on executive function was 0.574 （95% CI： 0.555~0.594）. Self-hate （indirect effect value of 0.160， 95% CI： 0.145~0.175） and negative affect （indirect effect value of 0.143， 95% CI： 0.129~0.158）， separately from each other， mediated the relationship between perceived stress and executive function， and a chained mediation effect of self-hate and negative affect was also documented （indirect effect value of 0.065， 95% CI： 0.058~0.073）， accounting for 27.87%， 24.91% and 11.32% of the total effect， respectively. ConclusionThe perceived stress of adolescents may be a influencing factor of the executive function. Additionally， perceived stress can either directly affect executive function or indirectly through the separate or chained mediation via negative affect and self-hate.

Objective To explore the mediating effect of self-hate between adverse childhood experiences and depression,anxiety,and suicide risk in adolescents.Methods In Juxian county,Rizhao,Shangdong Province,a cross-sectional survey was conducted in 5 junior high schools and high schools using questionnaires.A total of 6838 valid questionnaires were collected.The assessment included a self-designed general information questionnaire,patient health questionnaire-9(PHQ-9),generalized anxiety disorder-7(GAD-7),the mini-international neuropsychiatric interview 5.0 suicide module,revised adverse childhood experience questionnaire(ACEQ-R),and self-hate scale(SHS)to evaluate relevant content.Results The detection rates of depression,anxiety,and suicide risk were significantly higher in girls(P<0.001)and in senior high school students(P<0.001).Adolescents with depression,anxiety,and suicide risk exhibited higher scores for adverse childhood experiences and self-hate compared to those without these conditions(P<0.001).Adverse childhood experiences indirectly predicted depression through self-hate with an indirect effect size of 0.1488,accounting for 60.86% of the total effect(P<0.001).Similarly,adverse childhood experiences indirectly predicted anxiety through self-hate with an indirect effect size of 0.1524,accounting for 62.87% of the total effect(P<0.001).Furthermore,adverse childhood experiences indirectly predicted the risk of suicide through self-hate with an indirect effect size of 0.0485,accounting for 49.44% of the total effect(P<0.001).Conclusions Adverse childhood experiences have predictive effects on depression,anxiety and suicide risk in adolescents,and self-hate plays a mediating role on depression,anxiety and suicide risk in adolescents.

Objective:To explore the impact of adverse childhood experience on self-injury behavior and the mediating role of self hating in adolescents.Methods:A cross-sectional survey was conducted in 6 high schools and 5 middle schools in Shandong Province from August 1 to December 31, 2022, using the adverse childhood experience questionnaire, self-hating scale and non-suicidal self-injury behavior rating questionnaire for adolescents. A total of 7 313 questionnaires were collected, of which 6 948 were valid. SPSS 22.0 software was used for Spearman correlation analysis, and biased-corrected non-parametric percentile Bootstrap method was used to test the significance of mediating effect.Results:(1) The scores of adverse childhood experience(4.0(2.0, 6.0)), self-hating (22.0 (13.0, 29.0)) and self-injury behavior (12.0 (7.0, 19.0)) in adolescents with self-injury behavior were higher than those without self-injury behavior(0(0, 2.0), 2.0(0, 9.0), 0(0, 1.0)), and the differences were statistically significant ( Z=-21.700, -22.654, -29.519, all P<0.001). (2) Adverse childhood experience was positively correlated with self-hating ( r=0.46, P<0.01) and self-injury behavior ( r=0.47, P<0.01). Self-hating was positively correlated with self-injury behavior ( r=0.51, P<0.01). (3) Adverse childhood experience directly predicted self-injury behavior with a direct effect of 0.163 (95% CI =0.127-0.200, P<0.01)and the effect size of 53.80%(0.163/0.303).Adverse childhood experiences indirectly predicted self-injury behavior through self-hating, with an indirect effect of 0.140 (95% CI=0.122-0.160, P<0.001) and the effect size of 46.20%(0.140/0.303).The total effect was 0.303 (95% CI=0.270-0.336, P<0.001). Conclusions:There is a close relationship between adverse childhood experiences, self-hating and self-injury behavior in adolescents. Adverse childhood experiences can directly predict self-injury behavior, and can also indirectly affect self-injury behavior through self-hating.

Objective:To explore the mediating role of self-hating in the influence of adverse childhood experiences on adolescents' negative emotions.Methods:A questionnaire method was used to collect demographic variables, and 7 012 valid questionnaires were obtained from adolescents by applying the revised adverse childhood experiences questionnaire, patient health questionnaire-4, and self-hate scale from May 1 to May 30, 2022, in five high schools(90 classes) and five junior high schools(60 classes) in Rizhao city, Shandong province, China. Data entry and analysis were performed by SPSS 22.0 software.Mann-Whitney U test was used for the comparison between demographic variables and other variables, and the correlations between variables were expressed by Spearman correlation coefficient. AMOS 23.0 software was applied for testing the mediating and moderating effects of variables. Results:(1)There were significant positive correlations between adverse childhood experiences(0(2)) and negative emotion(3(10))( r=0.459, P<0.01), self-hating(2(4))( r=0.427, P<0.01). There were significant positive correlations between self-hating and negative emotion( r=0.566, P<0.01). (2) Self-hating played a mediating role between adverse childhood experience and adolescent negative emotion, and the mediating effect was 0.299, accounted for 61.27% of the total effect.(3) The mediating pathway of self-hated was moderated by gender, with girls' adverse childhood experiences( Bsimple=2.428, t=39.585, P<0.05) predicting self-hating more than boys( Bsimple=1.641, t=25.355, P<0.05). Conclusion:Adverse childhood experiences can predict adolescents' negative emotions, and self-disgusting can also affect adolescents' negative emotions.Gender plays a moderating role in the mediating pathway.

Objective:To explore the situation of insomnia, fatigue, depression, anxiety and cognitive impairment in adolescents with different characteristics, and the chain mediating effect of fatigue, depression and anxiety on insomnia and cognitive impairment.Methods:The general demographic data of 6 014 adolescents were collected.Insomnia severity index (ISI), the multidimensional fatigue inventory (MFI-20), patient health questionnaire-9 (PHQ-9), generalized anxiety disorder-7 (GAD-7) and perceived deficits questionnaire-depression(PDQ-D) were used to compare the insomnia, fatigue, depression, anxiety and cognitive impairment of adolescents with different characteristics.Spearman correlation analysis was conducted by SPSS 20.0 software.The significance of mediating effect was tested by deviation corrected nonparametric percentile Bootstrap method using SPSS macro program PROCESS.Results:The detection rates of insomnia, fatigue, depression, anxiety and cognitive impairment were different in adolescents with different genders, grades and academic achievements.Cognitive impairment was significantly positively correlated with insomnia ( r=0.654, P<0.01), fatigue ( r=0.476, P<0.01), depression ( r=0.677, P<0.01), anxiety ( r=0.655, P<0.01), which was suitable for mediating effect test.Fatigue, depression and anxiety in adolescents had a chain mediating effect between insomnia and cognitive impairment.Insomnia indirectly affects cognition by affecting fatigue and depressive symptoms.The intermediary effect value was 1.253, the effect amount was 55.60%, and the total effect was 2.254.Insomnia indirectly affects cognition by affecting fatigue and anxiety symptoms.The intermediary effect value was 1.161, the effect amount was 51.50%, and the total effect was 2.254. Conclusion:Insomnia can not only directly affect their cognitive impairment, but also indirectly affect their cognitive impairment through the chain mediation of fatigue, depression and anxiety of adolescents.

ObjectiveTo discuss the relationship between objective sleep quality and cognitive function in remission depression patients with insomnia. MethodsA total of 47 patients with depression in remission in Beijing Huilongguan Hospital were enrolled. Insomnia Severity Index （ISI） and the sleep efficiency calculated by the first four items of Pittsburgh Sleep Quality Index （PSQI） were defined as insomnia. Among the selected patients， 22 subjects were classified into insomnia group， and 25 subjects in non-insomnia group. The objective sleep status of all subjects was evaluated by polysomnography （PSG）， and the cognitive function was evaluated with the Repeatable Battery for Assessment of Neuropsychological Status （RBANS）. A regression model was established to explore the relationship between objective sleep quality and cognitive function in remission depression patients with insomnia. ResultsThere was statistically significant difference in immediate memory factor scores of RBANS between depression patients in remission with and without insomnia （t=-2.102， P<0.05）. The sleep efficiency （Z=-2.113， P<0.05）， the proportion of N3 sleep stage （Z=-3.175， P<0.01） and the duration of N3 sleep stage （Z=-3.196， P<0.01） in insomnia group were all lower than those in non-insomnia group， and the nocturnal awakening （Z=-2.058， P<0.01）， the proportion of N1 sleep stage （Z=-2.399， P<0.05） and the duration of N1 sleep stage （Z=-2.463， P<0.05） were higher than those of the insomnia group. Within insomnia group， the increased proportion of REM sleep was correlated with the improvement of attention function （β=0.953， 95% CI： 0.123~2.038， P<0.05）， and the increase of nocturnal awakening was correlated with the decline of delayed memory （β=-0.173， 95% CI： -0.325~-0.024， P<0.05）. ConclusionObjective sleep is associated with cognitive impairment in remission depression patients with insomnia， the proportion of REM sleep has a positive impact on attention function， and frequent nocturnal awakening at night has a negative impact on delayed memory.

Objective: To explore the relationship among cognitive flexibility, depression and eating attitude of adolescents and the influencing factors of eating attitude. Methods: A total of 1 231 subjects were assessed using general information questionnaire, Kutcher Adolescent Depression Scale 11 item(KADS-11), Cognitive Flexibility Inventory(CFI), Eating Attitude Test 26(EAT-26). Data were analyzed by independent sample t-test, univariate linear regression, spearman correlation analysis and Logistic regression. Results: There were significant differences in EAT 26 among adolescents between genders and between those with or without depression(P<0.01). Statistically significant differences were observed in CFI, flexible control and KADS 11 among adolescents with or without eating disorders(P<0.01). The scores of EAT 26 was negatively correlated with CFI (r=-0.19, P<0.01) and flexible control(r=-0.23, P<0.01). And there was a significant positive correlation between EAT 26 and KADS 11(r=0.23, P<0.01). Female(OR=2.40, 95%CI=1.87-3.23), depression (OR=1.76, 95%CI=1.35-2.29) and poor flexible control (OR=1.94, 95%CI=1.48-2.54) were risk factors for eating disorders. Conclusion Female, individuals with depressive symptoms or with poor flexible control ability are more likely to have eating disorders which need more attention.

Objective: To investigate the social support of medical students during the outbreak of COVID-19 and its mediating effect on the correlation between epidemic exposure and depression with anxiety. Methods: A total of 5 593 medical students were enrolled, and Social Support Rating Scale(SSRS), Patient Health Questionnaire-9 and 7-tiem Generalize Anxiety Disorder Scale were used to measure. Results: The social support score of SSRS of male students was lower than that of female students (t=-4.36, P<0.05) and juniors and seniors scored lower than other grades(F=4.84, P<0.05). Epidemic exposure proportion was positively correlated with both depressive proportionand anxiety proportion(r=0.05, 0.06, P<0.01), while epidemic exposure and depressive proportion and anxiety proportion were negatively correlated with social support score(r=-0.05, -0.25, -0.19, P<0.01). After controlling for gender and grade, the mediating effect of social support in the correlation between epidemic exposure and depression accounted for 26.6% of the total effect, and the mediating effect of subjective support and supportive utilization was 32.3% and 25.7% respectively. After controlling for gender and grade, the mediating effect of social support in the correlation between epidemic exposure and depression accounted for 20.0% of the total effect, and the mediating effect of subjective support and supportive utilization was 15.9% and 12.2% respectively. Conclusion Social support has partially mediating effect in the correlation between epidemic exposure with depression and anxiety.
