Correlative factors for organic psychotic symptoms in patients following traumatic brain injury.

OBJECTIVE: To investigate the correlative factors for organic psychotic symptoms following traumatic brain injury (TBI). METHODS: In the current study, 391 subjects who had undergone forensic identification of the organic mental disorders due to TBI were included, both the demographic and post-traumatic information collected. The relevant data were statistically analyzed in those confirmed as organic psychotic syndrome according to Chinese Classification of Mental Disorders 3rd version (CCMD-3). RESULTS: Fifty-two subjects (13.3%) were identified as organic psychotic symptoms. The chi-square test showed that the detectable organic psychotic symptoms were associated with the marriage status, damage nature, injury severity and treatment, and the multivariate logistic regression analysis revealed good fitness of treatment and injury severity with the regression model (OR = 0.044, 95% CI: 0.017-0.114; OR = 2.145, 95% CI: 1.201-3.832, respectively). CONCLUSION: The risks of organic psychotic symptoms following TBI can be involved in the alternative of craniotomy for the cases with trauma and moderate brain injury.

Relationship between stress response and depression in vocational medical school students in the COVID-19 epidemic: A moderated mediation model.

To investigate the relationship between stress response and depression in vocational medical school students at the initial stage of COVID-19 epidemic, and to explore the mediating role of meaning in life and the moderating role of prosocial behavior. The COVID-19 Stress Response Questionnaire, the Meaning in Life Questionnaire, the Prosocial Behavior Scale and the Depression Scale, were used to investigate 3526 vocational medical school students. The results showed that: (1) The relationship between stress response and depression in vocational medical school students was partially mediated by presence of meaning and search for meaning. Stress response has indirect effect on depression of vocational medical school students through meaning in life. (2) Prosocial behavior moderated the relationship between meaning in life and depression. Specifically, meaning in life has a more significant effect on depression for college students with higher levels of prosocial behavior.

Moderating Role of Resilience Between Depression and Stress Response of Vocational Middle School Students During the COVID-19 Pandemic.

Object: In this study, we aimed to explore the influences of stress responses and psychological resilience on depression of vocational middle school students during the initial COVID-19 outbreak in China. Methods: An online questionnaire survey on the students of a medical school in Jiangxi Province, China, and obtained 3,532 valid questionnaires. A self-compiled general situation questionnaire, Stress Response of COVID-19 Questionnaire, the Resilience Scale for Chinese Adolescents and Center for Epidemiological Studies Depression Scale (CES-D) were used. Hierarchical regression analysis was used to explore the regulatory role of psychological resilience between stress response and depression. Results: (1) There were significant differences in gender between vocational middle school students' evaluation (t = 3.07, P = 0.002) and defense (t = 3.28, P = 0.001) of the pandemic. Males had higher cognitive evaluation of the pandemic than females, and females had more defense against the pandemic than males. (2) There is a significant difference between vocational middle school students from different grades in depression level (F = 3.62, P = 0.03), pneumonia defense (F = 13.65, P < 0.001) and pneumonia panic (F = 3.10, P = 0.045). (3) Depression level (F = 7.17, P < 0.001), pneumonia evaluation (F = 2.78, P = 0.04) and pneumonia panic (F = 3.32, P = 0.02) of the students concerning the spatial distance of the pandemic. (4) The severity of urban pandemic affects the evaluation of pneumonia among vocational middle school students. (5) Depression was negatively correlated with psychological resilience and pneumonia evaluation, and positively correlated with pneumonia panic. Psychological resilience was positively correlated with pneumonia evaluation and pneumonia defense, and negatively correlated with pneumonia panic. (6) Psychological resilience could reduce the level of depression caused by pneumonia evaluation and pneumonia panic. Conclusion: There were significant differences in depression level and stress responses in grades, gender and spatial distance of pandemic. Resilience has a significant negative moderator effect on the relationship between pandemic panic and depression. Resilience has a significant positive moderator effect on the relationship between pandemic evaluation and depression.

[Evaluating on recognition impairment after traumatic brain injury with WCST].

OBJECTIVE: To explore the value of Wisconsin Card Sorting Test (WCST) in evaluating the recognition impairment after traumatic brain injury (TB1). METHODS: WCST and Wechsler Adult Intelligence Scale Revised in China (WAIS-RC) were adopted to assess the cognitive function in 186 patients with brain injury (experimental group) and 180 healthy volunteers (control group), respectively. The cognition between the experimental group and the control group was compared. The correlation between WCST and IQ was analyzed. The correlation between age, education level, the severity of TBI and the executive function were also analyzed. RESULTS: (1) The performances of WAIS-RC and WCST in the experimental group were significantly worse than that of the control group. (2) There were significantly negative correlation between the performance of total errors, percentage of preservative errors, percentage of random errors, response number on first category and IQ (P < 0.05). While there were significantly positive correlation between the categories completed, percentage of conceptual level and IQ (P < 0.05). (3) There was significantly negative correlation between percentage of conceptual level and the severity of TBI. While there were significantly positive correlation between percentage of preservative errors, percentage of random errors, response number on first category and the severity of TBI. CONCLUSION: WCST could be an important method in evaluating cognition of patients with brain injury.
