Reliability and validity of the Chinese version of the Childhood Trauma Questionnaire-Short Form for inpatients with schizophrenia

Factor analysis and evaluation of one-year test-retest reliability of the 33-item Childhood Trauma Questionnaire in Chinese adolescents

The 33-item Childhood Trauma Questionnaire (CTQ-33) is a recently developed tool expanded from the 28-item Childhood Trauma Questionnaire (CTQ-28) to assess childhood trauma events, which showed good test-retest reliability over 2 weeks. However, little is known regarding the factor structure and long-term test-retest reliability of the CTQ-33. To fill such a gap, this study investigated the factorial validity of the CTQ-33 and test-retest reliability of the scale over a relatively long interval of 1 year. Data on demographics, the CTQ-33 scores, and mental health statuses such as depressive/anxiety symptoms were collected in Chinese adolescents (n = 188) twice across a one-year period. Results of the confirmatory factor analysis (CFA) revealed that the Chinese version of CTQ-33 has close factor validity when compared to the original CTQ-28 in college students. Furthermore, the total and most subscale scores of the CTQ-33 have fair to good test-retest reliability (intra-class correlation coefficients >0.6 for the total score, and > 0.4 for most subscales), except for the physical abuse subscale. Moreover, we replicated previous findings of significant positive relationships between levels of different childhood trauma subtypes using the CTQ-33. These findings provide initial evidence supporting that the CTQ-33 is overall reliable to assess childhood traumatic events in adolescents over relatively long intervals.

Childhood maltreatment associated suicidal risk in Chinese children and adolescents: a mediation of resilience

BACKGROUND

Existing evidence suggests that children and adolescents who had experienced childhood maltreatment (CM) are at higher suicidal risk. However, the mediation role of resilience in this association remains unclear. We aim to investigate the mediation via resilience in the associations between CM and three suicidal risk indicators (suicidal ideation, SI; suicidal plan, SP; suicidal attempt, SA) among a large sample of Chinese children and adolescents.

METHODS

A population-based cross-sectional survey was conducted in southwestern China Yunnan province. A total of 9723 children and adolescents were included and analyzed by using a multi-stage stratified cluster sampling design. Univariate and multivariate logistic regression models were fitted to explore the associations between CM, resilience, and the three suicidal risk indicators, dose-response trends further elucidated by using the restricted cubic splines. Path models were adopted to estimate the mediation of resilience.

RESULTS

The estimated prevalence rates for one-year SI, SP and SA were 32.86% (95% CI: 31.93-33.80%), 19.36% (95% CI: 18.57-20.16%) and 9.07% (95% CI: 8.51-9.66%). After adjustment, CM significantly associated with all 3 suicidal risk indicators, and the odds ratios (ORs) were 2.13 (95% CI: 1.91-2.37), 2.45 (95% CI: 2.13-2.81), and 3.61 (95% CI: 2.90-4.52) for one-year SI, SP, and SA, respectively. Path models revealed that resilience significantly mediated the associations between CM and the three suicidal risk indicators, and among all dimensions of resilience, family support presented the strongest mediation consistently.

CONCLUSIONS

Our study results suggest that intervention measures which focusing on improving psychological resilience might be effective in reducing suicidal risk for children and adolescents who had experienced maltreatment. Prospective studies should be done to corroborate our findings.

Interleukin-1β moderates the relationships between middle frontal-mACC/insular connectivity and depressive symptoms in bipolar II depression

The functional alterations of the brain in bipolar II depression (BDII-D) and their clinical and inflammatory associations are understudied. We aim to investigate the functional brain alterations in BDII-D and their relationships with inflammation, childhood adversity, and psychiatric symptoms, and to examine the moderating effects among these factors. Using z-normalized amplitude of low-frequency fluctuation (zALFF), we assessed the whole-brain resting-state functional activity between 147 BDII-D individuals and 150 healthy controls (HCs). Differential ALFF regions were selected as seeds for functional connectivity analysis to observe brain connectivity alterations resulting from abnormal regional activity. Four inflammatory cytokines including interleukin (IL)-6, IL-1β, tumor necrosis factor (TNF)-α, and C-reactive protein (CRP) and five clinical scales including Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA), Positive and Negative Syndrome Scale (PANSS), Columbia-Suicide Severity Rating Scale (C-SSRS), and Childhood Trauma Questionnaire (CTQ) were tested and assessed in BDII-D. Partial correlations with multiple comparison corrections identified relationships between brain function and inflammation, childhood adversity, and psychiatric symptoms. Moderation analysis was conducted based on correlation results and previous findings. Compared to HCs, BDII-D individuals displayed significantly lower zALFF in the superior and middle frontal gyri (SFG and MFG) and insula, but higher zALFF in the occipital-temporal area. Only the MFG and insula-related connectivity exhibited significant differences between groups. Within BDII-D, lower right insula zALFF value correlated with higher IL-6, CRP, and emotional adversity scores, while lower right MFG zALFF was related to higher CRP and physical abuse scores. Higher right MFG-mid-anterior cingulate cortex (mACC) connectivity was associated with higher IL-1β. Moreover, IL-1β moderated associations between higher right MFG-mACC/insula connectivity and greater depressive symptoms. This study reveals that abnormal functional alterations in the right MFG and right insula were associated with elevated inflammation, childhood adversity, and depressive symptoms in BDII-D. IL-1β may moderate the relationship between MFG-related connectivity and depressive symptoms.

Factors related to suicidal ideation of schizophrenia patients in China: a study based on decision tree and logistic regression model

This study aimed to investigate the factors associated with suicidal ideation in schizophrenia patients in China using decision tree and logistic regression models. From October 2020 to March 2022, patients with schizophrenia were chosen from Chifeng Anding Hospital and Daqing Third Hospital in Heilongjiang Province. A total of 300 patients with schizophrenia who met the inclusion criteria were investigated by questionnaire. The questionnaire covered general data, suicidal ideation, childhood trauma, social support, depressive symptoms and psychological resilience. Logistic regression analysis revealed that childhood trauma and depressive symptoms were risk factors for suicidal ideation in schizophrenia (OR = 2.330, 95%CI: 1.177 ~ 4.614; OR = 10.619, 95%CI: 5.199 ~ 21.688), while psychological resilience was a protective factor for suicidal ideation in schizophrenia (OR = 0.173, 95%CI: 0.073 ~ 0.409). The results of the decision tree model analysis demonstrated that depressive symptoms, psychological resilience and childhood trauma were influential factors for suicidal ideation in patients with schizophrenia (p < 0.05). The area under the ROC for the logistic regression model and the decision tree model were 0.868 (95% CI: 0.821 ~ 0.916) and 0.863 (95% CI: 0.814 ~ 0.912) respectively, indicating excellent accuracy of the models. Meanwhile, the logistic regression model had a sensitivity of 0.834 and a specificity of 0.743 when the Youden index was at its maximum. The decision tree model had a sensitivity of 0.768 and a specificity of 0.8. Decision trees in combination with logistic regression models are of high value in the study of factors influencing suicidal ideation in schizophrenia patients.

Effects of childhood trauma on the symptom-level relation between depression, anxiety, stress, and problematic smartphone use: A network analysis

BACKGROUND

Childhood trauma experience is closely associated with depression, anxiety, stress, and problematic smartphone use (PSU). However, few studies have explored the complex symptom-level relations between these variables among people with and without trauma experiences, leaving a gap in treating and alleviating these mental disorders among individuals with childhood trauma.

METHODS

The current study used a convenience sampling method and recruited 2708 participants who completed Childhood Trauma Questionnaire-Short Form (CTQ-SF), Depression Anxiety and Stress Scales (DASS-21), and Mobile Phone Addiction Tendency Scale (MPATS), dividing them into trauma (n = 1454, Mean age = 19.67) and no-trauma (n = 1254, Mean age = 19.57) groups according to the cut-off scores of CTQ-SF. Symptom network analysis and network comparison test were conducted to construct and compare the network models between trauma and no-trauma groups.

RESULTS

The findings indicate that the trauma group and females exhibit greater average levels of DASS-21 and PSU symptoms compared to the no-trauma group and males, respectively. Additionally, the edge between "Stress" and "Anxiety" is the strongest across trauma and no-trauma groups. "Social comfort" is a bridge symptom of the trauma group network and the results of bridge symptoms in the no-trauma group are not stable.

LIMITATIONS

This study did not categorize all individuals according to specific types of trauma experiences and it is a cross-sectional design. The prevalences calculated in this study may not be generalizable.

CONCLUSIONS

Interventions targeting different bridge symptoms in the trauma and no-trauma network models may help reduce the severity of symptoms.

Psychological Resilience Mediates the Association Between Childhood Maltreatment and Self-Harm Phenotype in Chinese Early Adolescents

Self-harm (SH) increases significantly in early adolescence with great variability, and childhood maltreatment (CM) contributes to this increase. Understanding the developmental pathway from CM to SH could provide clues for SH prevention. This study used latent class analysis (LCA) to detect the phenotype of SH and explored the role of psychological resilience in the pathway from the CM to SH phenotype among 5724 early adolescents (52.5% male). Three interpretable phenotypes of SH were identified: low SH (57.8%), medium SH (29.0%), and high SH (13.2%). Furthermore, CM was positively associated with the SH phenotype, psychological resilience mediated the association between CM and the SH phenotype (all ps < 0.001), and a larger mediating effect was observed in the medium SH (22.41%). Our findings offer new perspectives that improving psychological resilience can be used as an efficient intervention to reduce the risk of SH among early adolescents who have experienced CM.

The impact of childhood trauma on Adolescent Depressive Symptoms: the Chain Mediating role of borderline personality traits and self-control

BACKGROUND

The adolescent depression associated with childhood trauma has been confirmed, but the underlying mechanisms remain unclear. This study aims to explore the chain-mediated role of borderline personality traits and self-control in the relationship between childhood trauma and adolescent depression.

METHODS

A cross-sectional study was conducted on 2,664 students from a senior high school through online questionnaires from October to December 2022 in Henan, China. Childhood Trauma Questionnaire-Short Form, Borderline Personality Dimension of Personality Diagnostic Questionnaire-4, Self-Control Scale, and Children's Depression Inventory were used to measure childhood trauma, borderline personality traits, and self-control.

RESULTS

The prevalence of depression in adolescents was 21.17%, while the prevalence of borderline personality was 12.00%. childhood trauma (r = 0.50, p < 0.001) and borderline personality traits (r = 0.60, p < 0.001) were positively correlated with adolescent depressive symptoms, while self-control was negatively correlated with depressive symptoms (r = - 0.50, p < 0.001). Borderline personality traits and Self-control both play a mediating role in childhood trauma and depressive symptoms, and the mediating effect values are 0.116 (95%CI = [0.098, 0.137]), and 0.022 (95%CI = [0.012, 0.032]) respectively. The chain mediating effect of borderline personality traits and self-control on the relationship between childhood trauma and depressive symptoms was significant (effect value: 0.034, 95%CI = [0.028, 0.042]).

CONCLUSIONS

Childhood trauma can predict depressive symptoms in adolescents due to the formation of borderline personality traits and the reduction of self-control. These findings are important for understanding the formation of personality traits, self-control abilities and coping strategies shaped by traumatic experiences in adolescents.

Childhood abuse and craving in methamphetamine-dependent individuals: the mediating role of alexithymia

Individuals with a history of childhood abuse (CA, including neglect and abuse by caregivers before the age of 18 years) have more severe substance dependence problems than those without a history of childhood abuse. However, whether a history of CA exacerbates craving and the mechanism of this effect remain largely unknown. The aim of this study was to explore the role of alexithymia in the effects of CA on craving in a large sample of methamphetamine-dependent individuals based on latent vulnerability theory. A total of 324 methamphetamine-dependent individuals who met DSM-5 criteria for substance use disorder were recruited. CA, alexithymia, and craving data were collected from the Childhood Trauma Questionnaire, the Toronto Alexithymia Scale-20, and the Obsessive Compulsive Drug Use Scale, respectively. t tests and ANCOVA were conducted to compare variables between the CA and non-CA groups, while partial correlation and mediation analyses were conducted to examine the potential mediating role of alexithymia in the relationship between CA and craving. Abused methamphetamine-dependent individuals reported higher levels of craving and higher levels of alexithymia than those of non-abused methamphetamine-dependent individuals. Alexithymia partially mediated the link between CA and craving, especially the effect of CA on craving frequency was fully mediated by alexithymia. Our findings reveal that a history of childhood abuse has a lasting effect on craving in stimulant-dependent individuals, and alexithymia contributes to some extent to the severity of substance abuse problems in abused methamphetamine-dependent individuals.

Characteristics and risk factors of Health-Related Risky behaviors in adolescents with Depression

BACKGOUND

To explore the characteristics and risk factors for health-related risky behaviours (HRRBs) in adolescents with depression.

METHODS

A total of 136 adolescents aged 12-18 years who met the diagnostic criteria for depression, and 272 healthy controls. All the subjects were assessed with the Adolescent Health-Related Risky Behavior Inventory (AHRBI), and the AHRBI scores of the two groups were compared with the Mann-Whitney U test. The depression group was assessed with the Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), Childhood Trauma Questionnaire (CTQ), Cognitive Emotion Regulation Questionnaire (CERQ), Egna Minnen av Barndoms Uppfostran (EMBU), and Family Adaptability and Cohesion Scale (FACES II-CV). Spearman correlation analysis and multiple linear regression were used to explore the risk factors for HRRBs in adolescents with depression.

RESULTS

The AHRBI total score and five-factor scores of self-injury and suicide (SS), aggression and violence (AV), rule-breaking (RB), smoking and drinking (SD), and health-compromising behavior (HCB) in the depression group were higher than those in the control group. The severity of anxiety, catastrophizing, cognitive emotional regulation strategy (self-blame and blaming of others), the frequency of depression, physical neglect, and sexual abuse all increased the risk of HRRBs in adolescents with depression, and paternal emotional warmth and understanding had protective effects.

CONCLUSION

First, depressed adolescents exhibited significantly more HRRBs than healthy adolescents. Second, there are many risk factors for HRRBs in adolescents with depression, and the risk factors for different types of HRRBs are also different.

Different adverse childhood experiences and adolescents' altruism: The mediating role of life history strategy

INTRODUCTION

The present study sought to investigate whether the relationship between childhood trauma, childhood socioeconomic (SES), and adolescents' altruism were mediated by their life history strategies and different adverse childhood experiences may function diversely on altruism, with two waves of data collected 6 months apart in a longitudinal design among Chinese adolescents.

METHODS

A total of 658 adolescents (Mage  = 13.51, SD = 0.73 at T1) were recruited and completed the online survey; their life history strategies were measured by the Mini-K, the Delayed of Gratification Questionnaire (DOG), and the Chinese version of the Adolescent Risk-Taking Questionnaire (ARQ-RB) together, and their altruism was collected again after six months.

RESULTS

After controlling for gender and their altruism at T1, the results showed that childhood trauma (i.e., emotional maltreatment, physical maltreatment), as well as low SES and fast life history strategy, were significantly negatively correlated with adolescents' altruism at T2. Importantly, life history strategy at T1 mediated the relationship between T1 emotional maltreatment, T1 low SES, and adolescents' altruism at T2. However, the effect of physical maltreatment on altruism was not mediated by life history strategy.

CONCLUSIONS

This study indicated that emotional maltreatment and low SES can affect adolescents' altruism by influencing the formation of adolescents' life history strategies. The findings revealed the different influences of adverse childhood experiences on adolescents' altruism, which supplied new empirical evidence for the life history theory and provided certain reference values for cultivating adolescents' altruism.

Stigma and its associations with medication adherence in major depressive disorder

This study sought to evaluate internalized stigma (IS) and perceived stigma (PS), in persons (n = 522) living with major depressive disorder (MDD), with a view to analyzing the association of IS and PS with medication adherence in a cohort of participants with MDD in China. Perceived stigma is the awareness of societal negative views and attitudes towards depression, and IS is applying others' attitudes to oneself, both measured by the Depression Stigma Scale (DSS). Medication adherence was assessed using the Medication Adherence Rating Scale (MARS). We observed that 76.0 % of participants reported IS and 84.5 % reported PS. Factors associated with increased IS included older age, marital status, disease history, and a higher baseline Patient Health Questionnaire-9 (PHQ-9). Higher education level, family income, and scores on the Connor-Davidson Resilience Scale (CD-RISC) were associated with lower levels of IS. Higher education levels, Childhood Trauma Questionnaire (CTQ) scores, and living with others were also associated with higher PS, while engagement in exercise and higher number of prior episodes were associated with lower PS. IS had a negative association with medication adherence, whereas PS did not significantly associate with adherence. In conclusion, a testable hypothesis is derived from our data that strategies targeting IS amongst persons with MDD may improve overall rates of adherence to antidepressant treatment, a necessary prelude to improving recovery.

Comparison of ACE-IQ and CTQ-SF for child maltreatment assessment: Reliability, prevalence, and risk prediction

BACKGROUND

Child maltreatment has profound effects on mental health. The Childhood Trauma Questionnaire Short Form (CTQ-SF) and the Adverse Childhood Experiences International Questionnaire (ACE-IQ) are commonly used retrospective assessment tools for evaluating child maltreatment.

OBJECTIVE

This study aims to conduct a comprehensive comparison of the CTQ-SF and ACE-IQ, encompassing internal consistency, prevalence, and the predictive efficacy of trauma-related outcomes. It also seeks to enhance the scoring method of ACE-IQ based on the established comparability between the two instruments.

PARTICIPANTS AND SETTING

1484 college students from northern China were recruited, assessing demographic characteristics and outcomes related to traumatic experiences, including post-traumatic stress disorder (PTSD), complex post-traumatic stress disorder (CPTSD), borderline personality disorder (BPD), anxiety, and depression.

METHODS

A contingency correlation analysis was performed to evaluate the degree of agreement between the CTQ-SF and ACE-IQ. Binary logistic regression models were utilized to compare the predictive capabilities of distinct instruments.

RESULTS

CTQ-SF and ACE-IQ instruments display favorable internal consistency and notable correlations across shared categories. However, the predictive relationships between trauma type and adverse outcomes are inconsistent across instruments. The ACE-IQ, encompassing 13 trauma categories, demonstrate a lower AIC and BIC index, indicating a superior model fit for elucidating outcomes.

CONCLUSION

This study introduces a scoring methodology for ACE-IQ, improving the comparability of the two measures and emphasizing the importance of capturing the full range of maltreatment types a child may have experienced. These findings have significant implications for clinical and epidemiological research, providing valuable insights for understanding the impact of child maltreatment.

Childhood Trauma Questionnaire-Short Form: Evaluation of Factor Structure and Measurement Invariance

Childhood trauma is known to put individuals at risk for mental and physical challenges later in life. Retrospective assessment of early abuse and neglect is critical for prevention and intervention efforts targeted at reducing the negative impacts of childhood trauma. The Childhood Trauma Questionnaire-Short Form (CTQ-SF) is a widely used measure to assess trauma among adolescents and adults, though there are some inconsistencies with regard to its factor structure and psychometric properties. The purpose of the current study was twofold: (1) to evaluate the hypothesized five-factor structure of CTQ-SF and (2) to test measurement invariance (equivalence) of the instrument across gender and race in a large, nationally representative sample of US adults (N = 863). Confirmatory factor analysis results indicate that the five-factor model fit the data well. The results also show that the five-factor model is generally invariant by gender and racial/ethnic groups and that the form's subscales positively correlate with depression, anxiety, and abnormal inflammatory biomarker activity. Assessment is critical for the advocacy and treatment of individuals who have experienced abuse and neglect as children and adolescents. Our findings suggest that the CTQ-SF is a valuable tool for assessing childhood trauma and can be used in advocacy and treatment efforts.

Construction and verification of aggressive behavior risk prediction model in stable patients with schizophrenia

BACKGROUND

Among all types of mental disorders, individuals with schizophrenia exhibit the highest frequency of aggressive behavior. This disrupts the healthcare environment and poses threats to family life and social harmony. Present approaches fail to identify individuals with schizophrenia who are predisposed to aggressive behavior. In this study, we aimed to construct a risk prediction model for aggressive behavior in stable patients with schizophrenia, which may facilitate early identification of patients who are predisposed to aggression by assessing relevant factors, enabling the management of high-risk groups to mitigate and prevent aggressive behavior.

METHODS

A convenience sample of stable inpatients with schizophrenia were selected from Daqing Municipal Third Hospital and Chifeng Municipal Anding Hospital from March 2021 to July 2023. A total of 429 patients with stable schizophrenia who met the inclusion criteria were included. A survey was conducted with them using a questionnaire consisting of general information questionnaire, Positive and Negative Symptom Scale, Childhood Trauma Questionnaire-Short Form, Connor-Davidson Resilience Scale and Self-esteem Scale. Patients enrolled in this study were divided into aggressive and non-aggressive groups based on whether there was at least one obvious and recorded personal attack episode (including obvious wounding and self-injurious behavior) following diagnosis. Binary Logistic regression was used to determine the influencing factors, and R software was used to establish a nomogram model for predicting the risk of aggressive behavior. Bootstrap method was used for internal validation of the model, and the validation group was used for external validation. C statistic and calibration curve were used to evaluate the prediction performance of the model.

RESULTS

The model variables included Age, Duration of disease, Positive symptom, Childhood Trauma, Self-esteem and Resilience. The AUROC of the model was 0.790 (95% CI:0.729-0.851), the best cutoff value was 0.308; the sensitivity was 70.0%; the specificity was 81.4%; The C statistics of internal and external validation were 0.759 (95%CI:0.725-0.814) and 0.819 (95%CI:0.733-0.904), respectively; calibration curve and Brier score showed good fit.

CONCLUSIONS

The prediction model has a good degree of discrimination and calibration, which can intuitively and easily screen the high risk of aggressive behavior in stable patients with schizophrenia, and provide references for early screening and intervention.

Cognitive reappraisal and corresponding neural basis mediate the association between childhood maltreatment and depression

BACKGROUND

Childhood maltreatment is considered as a robust predictor of depression. However, the underlying psychological and neurological mechanisms linking childhood maltreatment and depression remain poorly understood. Sufficient evidence demonstrates emotion dysregulation in individuals who have experienced childhood maltreatment, but it is unknown whether these changes represent vulnerability for depression. Here we speculated that decreased cognitive reappraisal and its corresponding neural basis might explain the relationship between childhood maltreatment and follow-up depression.

METHODS

First, we investigated whether cognitive reappraisal can explain the relationship between childhood maltreatment and depression, with a cross-sectional (n = 657) behavioral sample. Then we recruit 38 maltreated participants and 27 controls to complete the cognitive reappraisal functional magnetic resonance imaging (fMRI) task. The between-group difference in brain activation and functional connectivity (FC) were tested using independent t-tests. Finally, we investigated the relationship between childhood maltreatment, task-based brain activity and depression.

RESULTS

The behavior results suggested that cognitive reappraisal mediates the association between childhood maltreatment and depression. In addition, the maltreated group exhibited lower activation of orbitofrontal cortex (OFC) and higher FC of between the dorsolateral prefrontal cortex (DLPFC), posterior cingulate cortex (PCC), OFC, and amygdala during cognitive reappraisal, compared with healthy controls. Furthermore, the FC of DLPFC-amygdala mediates the association between childhood maltreatment and depression.

CONCLUSION

In summary, childhood maltreatment is associated with inefficient cognitive reappraisal ability, manifesting as aberrant modulation of cortical areas on amygdala. These cognitive and neural deficits might explain the relationship between childhood maltreatment and risk of depression in later life.

Correlation between childhood trauma experience and depressive symptoms among young adults: The potential mediating role of loneliness

BACKGROUND

It is widely recognized that childhood trauma poses a significant risk of developing depressive symptoms. However, the underlying mediation mechanism between childhood trauma and depressive symptoms requires further exploration.

OBJECTIVE

This study focuses on exploring whether loneliness may act as a potential mediator between childhood trauma and depressive symptoms.

PARTICIPANTS AND SETTING

We analyzed a large sample of college students (N = 7293). Participants completed online questionnaires in the WeChat group.

METHODS

Childhood trauma, depressive symptoms, and loneliness were evaluated using the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Patient Health Questionnaire-9 (PHQ-9), and the University of California Los Angeles Loneliness Scale (UCLA-LS) respectively. The linear regression method was applied to explore the mediating role.

RESULTS

Gender, relationship with family, and left-behind experience are all substantial depressive symptoms risk factors. Childhood trauma was shown to be highly related to depressive symptoms, and this relationship was potentially mediated by loneliness.

CONCLUSIONS

Our research indicates that treating loneliness in those who have undergone childhood trauma may help prevent or treat depressive symptoms. Therefore, loneliness should be taken into consideration while treating and preventing depressive symptoms.

Childhood trauma and suicide risk in hospitalized patients with schizophrenia: the sequential mediating roles of pandemic related post-traumatic stress symptoms, sleep quality, and psychological distress

Introduction

Stressful global situation due to the COVID-19 pandemic caused a tremendous impact on mental health in hospitalized patients with schizophrenia. The mediating roles of psychological impact related to COVID-19, sleep quality, and psychological distress were investigated in the association between childhood trauma and suicidal risk in hospitalized patients with schizophrenia.

Methods

We analyzed cross-sectional data of 147 patients with schizophrenia and 189 healthy controls (HCs).

Results

Histories of childhood trauma and schizophrenia were good predictors of COVID-19-related psychological impact, global sleep quality, and psychological distress. Moreover, the series mediation model showed that the effect of childhood trauma on suicidal risk in hospitalized patients with schizophrenia was totally sequential mediated by the psychological impact of COVID-19, sleep quality, and psychological distress.

Conclusion

Clinicians need to recognize the increased suicidal risk associated with COVID-19-related psychological distress in schizophrenia patients with a history of childhood trauma.

Video game addiction in psychiatric adolescent population: A hospital-based study on the role of individualism from South China

BACKGROUND

For decades, video game-related behaviors have been investigated in different psychologic research, much of whose attention has been paid to video game addiction (VGA), while the differences between VGA and social media addiction (SMA) should have deserved more attention. In addition to detecting common risk factors of VGA, one core question is whether social inclination (individualism or collectivism) matters.

OBJECT

The objectives of this study were to clarify the prevalence of VGA and SMA,, identify the influencing factors of VGA, and clarify the relationships between VGA and adolescents' individualism-collectivism inclination.

METHOD

The survey was conducted among 110 adolescent psychiatric patients. For each interviewee, psychological scales were filled face to face. Path analysis was used to examine the causation structure of the childhood trauma-related symptoms.

RESULT

The prevalence of VGA was 40.9% (45 out of 110), and it was 41.8% for SMA (46 out of 110); childhood trauma, social media addiction, the individualistic inclination, and the rate of homosexuality were observed to be independent indicators for video game addiction (r2  = 0.46).

CONCLUSION

Psychological counseling on patients' internet-related behaviors may focus on the individualistic personality and possible childhood trauma, which are two important risk factors of video game addiction. It is recommended to distinguish between video game addiction and social addiction in clinical practice.

CSF1R regulates schizophrenia-related stress response and vascular association of microglia/macrophages

BACKGROUND

Microglia are known to regulate stress and anxiety in both humans and animal models. Psychosocial stress is the most common risk factor for the development of schizophrenia. However, how microglia/brain macrophages contribute to schizophrenia is not well established. We hypothesized that effector molecules expressed in microglia/macrophages were involved in schizophrenia via regulating stress susceptibility.

METHODS

We recruited a cohort of first episode schizophrenia (FES) patients (n = 51) and age- and sex-paired healthy controls (HCs) (n = 46) with evaluated stress perception. We performed blood RNA-sequencing (RNA-seq) and brain magnetic resonance imaging, and measured plasma level of colony stimulating factor 1 receptor (CSF1R). Furthermore, we studied a mouse model of chronic unpredictable stress (CUS) combined with a CSF1R inhibitor (CSF1Ri) (n = 9 ~ 10/group) on anxiety behaviours and microglial biology.

RESULTS

FES patients showed higher scores of perceived stress scale (PSS, p < 0.05), lower blood CSF1R mRNA (FDR = 0.003) and protein (p < 0.05) levels, and smaller volumes of the superior frontal gyrus and parahippocampal gyrus (both FDR < 0.05) than HCs. In blood RNA-seq, CSF1R-associated differentially expressed blood genes were related to brain development. Importantly, CSF1R facilitated a negative association of the superior frontal gyrus with PSS (p < 0.01) in HCs but not FES patients. In mouse CUS+CSF1Ri model, similarly as CUS, CSF1Ri enhanced anxiety (both p < 0.001). Genes for brain angiogenesis and intensity of CD31+-blood vessels were dampened after CUS-CSF1Ri treatment. Furthermore, CSF1Ri preferentially diminished juxta-vascular microglia/macrophages and induced microglia/macrophages morphological changes (all p < 0.05).

CONCLUSION

Microglial/macrophagic CSF1R regulated schizophrenia-associated stress and brain angiogenesis.

Profiles and predictors of mental health of university students in Hong Kong under the COVID-19 pandemic

This study investigated the mental health problems of university students in Hong Kong and related sociodemographic and psychosocial predictors under the pandemic. A total of 978 undergraduate students (mean age = 20.69 ± 1.61) completed an online questionnaire measuring sociodemographic factors, psychological morbidity, positive well-being, COVID-19 related stress and self-efficacy, and positive psychosocial attributes. Psychosocial risk factors included psychological morbidity, COVID-19 related stress, and difficulties encountered under the pandemic, whereas protective factors comprised pandemic related self-efficacy, positive psychological attributes, positive environmental factors, need satisfaction and positive perception toward service. Results showed that psychological morbidity in the participants was widespread, and it was related to sociodemographic factors, particularly family financial difficulties. While pandemic related stress positively predicted psychological morbidity and negatively predicted well-being indicators, COVID-19 self-efficacy showed an opposite effect. Besides, positive psychological attributes (resilience, emotional competence, and positive beliefs related to adversity) and environmental factors (healthy family functioning, peer support, and supportive community atmosphere) negatively predicted psychological morbidity and positively predicted well-being. Furthermore, need satisfaction and positive perception toward service were negatively associated with psychological morbidity and positively associated with well-being, while perceived difficulties showed an opposite effect.

Adverse childhood experiences, unhealthy lifestyle, and nonsuicidal self-injury: findings from six universities in Shaanxi province, China

Background

Nonsuicidal self-injury (NSSI) is a serious public health problem. The role of adverse childhood experiences (ACEs) and lifestyle on the risk for NSSI is still underexplored, especially among college students. We aimed to investigate the association of ACEs with the risk of NSSI, and effect modifications by lifestyle among college students.

Methods

A total of 18,723 college students from six universities were recruited through a multistage, random cluster sampling method in Shaanxi province, China. The Adverse Childhood Experiences International Questionnaire was used to assess ACEs for each participant, and the Chinese version of the Ottawa Self-injury Inventory was used to assess the presence or absence of NSSI behaviors. Information about lifestyle was collected by a self-designed questionnaire. The associations of NSSI with ACEs and lifestyle were analyzed using logistic regression models. Furthermore, we constructed a combination score of multiple lifestyles and evaluated whether lifestyle modified the effect of ACEs on the risk of NSSI.

Results

The prevalence of NSSI for the past 1 month, 6 months, and 12 months was 3.8, 5.3, and 6.5%, respectively. 82.6% of participants have reported experiencing at least one type of ACEs, and participants with higher levels of ACEs (≥4) were more likely to have higher odds of developing NSSI during the past 1 month (OR, 4.10; 95%CI, 3.38-4.97), 6 months (OR, 4.76; 95%CI, 4.03-5.62), and 12 months (OR, 5.62; 95%CI, 4.83-6.55), as compared with participants with low levels of ACEs (0-1). There were additive interactions between ACEs and lifestyle. Compared with participants with low levels of ACEs and healthy lifestyle, participants with high levels of ACEs and unhealthy lifestyle had the highest odds of NSSI during the past 1 month (OR, 5.56; 95%CI, 3.80-8.31), 6 months (OR, 6.62; 95%CI, 4.73-9.42), and 12 months (OR, 7.62; 95%CI, 5.59-10.52).

Conclusion

These results suggest that ACEs play an important role in the occurrence of NSSI among college students, especially in those with unhealthy lifestyle. Our findings may help develop targeted intervention strategies for the prevention of NSSI.

Symptoms mediate the relationship between childhood trauma and non-suicidal self-injury: A hospital-based study of adolescents with mood disorder

BACKGROUND

Childhood trauma has a significant impact on the development of adolescents, which may lead to interpersonal and psychological problems. Determining the incidence and consequences of childhood trauma in psychiatric clinical practice is of great significance.

METHODS

A survey was conducted among adolescents with mood disorders. Childhood Trauma Questionnaire (CTQ), the Adolescent Non-Suicidal-Self-Injury Behavior Function Assessment Scale (ANBFAS) and a series of psychological scales were filled face to face. Path analysis was used to examine the causation structure of childhood trauma-related symptoms.

RESULTS

A total of 117 participants (74.5%) had experienced at least one type of trauma. Interpersonal and psychological features of adolescent patients with childhood trauma were detailed in this study. The path analysis model showed that the relationships between childhood trauma and NSSI were mediated by depressive symptoms and thinking disorders, respectively, whereas depressive symptoms individually mediated the correlation between childhood trauma and sleep disturbances in adolescent patients with psychiatric disorders (χ2 /df = 1.23).

CONCLUSION

For adolescent patients with childhood trauma, psychological counseling for interpersonal relationships should start with families and peers. It is important to treat their depressive symptoms and thinking disorders and alleviate NSSI behavior and sleep disorders.

Gender-specific associations between types of childhood maltreatment and major depressive disorder: A matched case-control study

INTRODUCTION

Major depressive disorder (MDD) has been found to be nearly twice as prevalent in females as in males. One hypothesis proposed that abused females were particularly prone to MDD. We aim to examine the sex-specific associations between various types of childhood trauma and MDD.

METHODS

In this study, 290 outpatients diagnosed with MDD were recruited from Beijing Anding Hospital, and 290 healthy volunteers were recruited from neighborhoods nearby the hospital, with sex, age, and family history matched. Childhood Trauma Questionnaire-Short Form (CTQ-SF) developed by Bernstein et al. was used to assess the severity of five different types of childhood abuse and neglect. McNemar's test and conditional logistic regression models with potential confounders (i.e., marital status, educational level, and body mass index) controlled were used to explore the sex-specific associations between different types of childhood maltreatment and MDD.

RESULTS

In the full sample, patients with MDD showed a significant higher rate of any childhood maltreatment (i.e., emotional abuse, sexual abuse, physical abuse, emotional neglect, and physical neglect). Among females, all types of childhood abuse were statistically significant. For males, significant differences were only found in emotional abuse and in emotional neglect.

CONCLUSION

It would appear that MDD in the outpatients is associated with any type of childhood trauma in women and emotional abuse or neglect in men.

Heterogeneity of resilience and the curvilinear relationship between childhood trauma and resilience among people with schizophrenia

Background

As a group with a high incidence of childhood trauma, the differential characteristics of resilience in schizophrenia and its relationship with childhood trauma are still unclear.

Methods

A total of 626 individuals diagnosed with schizophrenia were selected from four psychiatric hospitals in northern China. Childhood trauma and resilience were measured using the Childhood Trauma Questionnaire-short form (CTQ-SF) and Connor-Davidson Resilience Scale (CD-RISC), respectively. Latent profile analysis (LPA) was used to identify the potential classes of resilience. A generalized additive mixed model (GAMM) and restricted cubic spline (RCS) was used to explore and determine the shape of the relationship between childhood trauma and resilience.

Results

Model fits of LPA showed three heterogeneous classes of resilience: moderate resilience levels (n = 312; 49.06%); high resilience levels (n = 171; 26.89%) and low resilience levels (n = 153; 24.06%). Resilience scores fluctuated depending on amount of exposure to childhood trauma. The GAMM results verified the non-linear relationship between resilience and childhood trauma, with an estimated degree of freedom higher than 1 (4.573) and p = 0.003. RCS fitted for ordinary least square (OLS) regression models determined a smooth continuous cubic curve of resilience across childhood trauma levels, and the two turning points of the curve line were 41.04 and 54.74 for childhood trauma.

Discussion

Our findings confirm the people-specific differences in the level of resilience in schizophrenia and describe the cubic curvilinear relationship between childhood trauma and resilience, which provides data support for mechanistic research and intervention in related fields.

Regional superficial amygdala resting-state functional connectivity in adults infers childhood maltreatment severity

Background

Childhood maltreatment (CM) is a potential risk factor for some neuropsychiatric disorders in adulthood (e.g. depression and anxiety) and alters trajectories of brain development. Accumulating evidence suggests that functional connectivity of the limbic system, especially the amygdala, is highly associated with childhood maltreatment, although not all studies have found this. These inconsistent results may be due to differential alterations of amygdala resting-state functional connectivity (rsFC) following childhood maltreatment.

Objective

Our aim was to investigate the relationship between the rsFC of amygdala subregions and CM severity, as well as to develop a stable rsFC-based model for inferring the severity of CM.

Methods

In this study, we employed the Childhood Trauma Questionnaire (CTQ) to assess CM severity in each individual. We explored the relationship between the rsFC of amygdala subregions (i.e. centromedial -CMA, basolateral -BLA, superficial-SFA amygdala) and CM experience in a discovery dataset of n = 110 healthy Chinese participants by linear multiple regression analysis. Subsequent dimensional and categorical approach were performed to elucidate the relationship between rsFCs and CM severity and CM subtypes, respectively. A support vector regression model was then conducted to validate the associations between rsFCs and total CTQ scores. Moreover, we also verified the model into another independent replication dataset (n = 38).

Results

Our findings suggested that childhood maltreatment was negatively associated with rsFC between the right superficial amygdala and perigenual anterior cingulate cortex (pgACC)/postcentral gyrus (PCG) but not the other two amygdala subregions. Moreover, SFA-pgACC coupling was more associated with physical neglect whereas the SFA-PCG was more related to emotional neglect. In addition, supervised machine learning confirmed that using these two rsFCs as predictors could stably estimate continuous maltreatment severity in both discovery and replication datasets.

Conclusion

The current study supports that the rsFCs of superficial amygdala are related to childhood maltreatment and which may be a potential biomarker for the effects of childhood maltreatment-related psychiatric disorders (i.e. depression and anxiety).

Association between early life adversity and allostatic load in girls with precocious puberty

CONTEXT

The mechanisms underlying the elevated long-term health risk in girls with precocious puberty remain unclear, but might result from physiological wear and tear associated with greater exposure to early life adversity.

OBJECTIVE

This study aims to explore early life adversity in girls with precocious puberty and its association with allostatic load.

METHODS

Early life adversity and hair cortisol concentration were measured among 213 girls with precocious puberty (8.21 ± 1.07). Allostatic load score is constructed by using 13 physiological biomarkers representing four systems and hair cortisol concentration. Multivariate linear regression models have estimated the associations between cumulative early life adversity exposure with total and system-specific allostatic load scores. Associations between cumulative early life adversity and the risk of high allostatic load (3 + high-risk biomarkers) were tested using binary logistics regression.

RESULTS

More than two-thirds (67.6%) of girls with central precocious puberty reported two or more early life adversity exposure. Compared to those with no early life adversity exposure, girls who reported early life adversity score ≥ 2 had significantly higher total allostatic load score (β: 1.20-1.64, P < 0.001). Metabolic system was more sensitive to cumulative early life adversity exposure, each form of early life adversity exposure was associated with 0.48-unit increases in metabolic allostatic load score (95%CI: 0.06, 0.90, P = 0.026). Girls reported early life adversity score ≥ 3 were three times more likely to have a high allostatic load compared with those without early life adversity exposure in both unadjusted and adjusted models (OR_adjusted=3.83, 95%CI: 1.17, 12.55, P = 0.001).

CONCLUSION

Multisystem physiological dysregulation is observed in girls with central precocious puberty, which might result from cumulative wear-and-tear associated with early life adversity.

Trauma measures for use with psychosis populations: A systematic review of psychometric properties using COSMIN

Traumatic events play a key role in the development and course of psychosis. Psychotic symptoms themselves and coercive treatment practices can be inherently traumatic. Hence, reliable and valid methods of assessing trauma and its impact (i.e., Post-Traumatic Stress Disorder (PTSD) symptomology) are essential for use with people with psychosis. Many measures are available to select from, but this is the first review to appraise the psychometric properties of trauma measures to guide decision making regarding instrument use. The review was prospectively registered on Prospero (CRD42022306100). Evaluation of methodological and psychometric quality followed Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) guidance. Twenty-four articles were eligible, with sixteen trauma measures evaluated. Childhood Trauma Questionnaire- Short Form demonstrated the most robust evidence for assessing experience of trauma. The Trauma and Life Experience (TALE) checklist was the only measure to include specific psychosis and iatrogenic harm items. For PTSD measures, the Symptoms of Trauma Scale and PTSD Symptom Scale- Self Report had the highest quality evidence. Psychometric strengths and weaknesses of various trauma measures are comprehensively evaluated, highlighting future research directions to strengthen the evidence base with emphasis on further evaluation of the TALE, which integrates trauma specific to psychosis.

Association between childhood trauma and white matter deficits in first-episode schizophrenia

OBJECTIVE

This study aimed to investigate the relationship between childhood trauma (ChT) and white matter (WM) deficits in first-episode schizophrenia (FES).

METHODS

A total of 103 individuals with FES and 206 healthy control individuals (HCs) were enrolled and assessed based on ChT Questionnaire (CTQ) and Positive and Negative Symptoms Scale (PANSS). Diffusion tensor imaging was acquired on a Signa 3.0 T scanner. Map of fractional anisotropy (FA) was analyzed using Tract-Based Spatial Statistics. Hierarchical logistic regression analyses were used to examine associations of sociodemographic characteristics, total CTQ scores, and WM deficits.

RESULTS

Compared with the HCs group, the FES group showed significantly lower FA in several WM bundles (left anterior thalamic radiation, left inferior frontal-occipital fasciculus, left cingulum, forceps major, and forceps minor), and the mean FA value in these WM bundles was inversely related to the total CTQ score. In addition, a higher CTQ score may increase the risk of schizophrenia, while higher FA values may decrease the risk of schizophrenia.

CONCLUSION

This study demonstrates that individuals with FES evince widespread cerebral WM abnormalities and that these abnormalities were associated with ChT. These results provide clues about the neural basis and potential biomarkers of schizophrenia.

The Role of Cognitive Deficits in Borderline Personality Disorder with Early Traumas: A Mediation Analysis

(1) Background: although studies of cognitive functions are still limited in borderline personality disorder (BPD), the initial evidence suggested that BPD patients have deficits of executive functions and social cognition. In addition, patients who report physical and psychic traumatic experiences in childhood and adolescence show considerable neurocognitive impairment and severe BPD symptoms. The present study has a twofold aim: (1) to evaluate the differences in neurocognitive performances between BPD patients and healthy controls and (2) to verify in the BPD patients group whether neurocognitive deficits have the role of mediating the effect of early traumas on BPD psychopathology. (2) Methods: 69 subjects were enrolled: 38 outpatients with a diagnosis of BPD (DSM-5) and 31 healthy controls. BPD patients were tested with the Borderline Personality Disorder Severity Index (BPDSI), and the Childhood Trauma Questionnaire-Short Form (CTQ-SF). All subjects were evaluated with the Iowa Gambling task (IGT), the Berg card sorting test (BCST), the Tower of London task (ToL), and the Reading-the-mind-in-the-eyes-test (RMET). Statistical analysis was performed with the analysis of variance to compare the cognitive performances between BPD patients and controls. A mediation analysis was conducted with the Sobel Test in the BPD patients group. The significance level was p ≤ 0.05. (3) Results: significant differences between the two groups were found for several parameters of all the cognitive tests examined: BCST, IGT, ToL, and RMET. Mediation analysis with the Sobel test demonstrated that the percentage of correct answers in the BCST (BCSTc) and the RMET score significantly mediated the relation between the CTQ total score and BPDSI total score. (4) Conclusions: BPD patients showed an impairment of the following executive functions: set shifting, decision making, planning and problem solving, and social cognition abilities, in comparison with controls. Our results suggested that the effect of early trauma on BPD psychopathology was mediated by a deficit in two cognitive domains: cognitive flexibility and social cognition.

Psychometric properties and normative data of the childhood trauma questionnaire-short form in Chinese adolescents

Background

The Childhood Trauma Questionnaire-Short Form (CTQ-SF) is a widely utilized instrument of childhood maltreatment (CM). However, psychometric properties and normative data of the CTQ-SF for Chinese adolescents are still unknown.

Objective

To examine psychometric properties and normative data of Chinese version CTQ-SF in a nationally representative sample of Chinese adolescents, including internal consistency reliability, test-retest reliability, structural validity, and convergent validity.

Method

A total of 20,951 adolescents aged 12 to 18 years were recruited from five provinces across China. Item analysis was used for 25 clinical items of the CTQ-SF. Confirmatory factor analysis was performed to examine fit indices of the factor structure. The Adverse Childhood Experiences Scale (ACEs) was used to evaluate convergent validity. The percentile ranks for scores of the CTQ-SF and each subscales were presented.

Results

According to the results of three methods in Item analysis, Item 4 should be dropped. The remaining 24 clinical items achieved satisfactory fits in an alternative four-factor model. The alternative CTQ-SF showed acceptable internal consistency and the Cronbach's α of the four subscales was 0.824 (Neglect), 0.755 (Sexual Abuse), 0.713 (Physical Abuse), and 0.666 (Emotional Abuse), respectively. Besides, test-retest reliability and convergent validity of the alternative CTQ-SF were also acceptable.

Conclusion

The alternative four-factor model CTQ-SF exhibits good reliability and validity among Chinese adolescents. Additionally, the normative information of the CTQ-SF could provide practical support for determining severity of different subtypes of CM.

Psychometric Properties of Childhood Trauma Questionnaire - Short Form (CTQ-SF) Indonesian Version

Abuse and neglect are increasingly occurring in various regions, including in Indonesia. The diversity of abuse and neglect in childhood and adolescence have an impact on neurobiological function damage so that it has long-term impacts on individuals who experience it. Unfortunately, in Indonesia there is no screening tool to assess the trauma of abuse and neglect in childhood and adolescence. This study aims to translate and obtain psychometric property of the Childhood Trauma Questionnaire (CTQ-SF) consisting of physical, emotional and sexual violence as well as physical and emotional neglect dimensions. The translation shows that the Indonesian version of the CTQ-SF has a good level of equivalence with the CTQ-SF. In addition, the classical test theory approach showed that the Indonesian version of CTQ-SF had a high reliability by the need of reviewing of the three items on the sexual abuse dan physical neglect dimensions. Nevertheless, a multidimensional approach of confirmatory factor analysis showed that the Indonesian version of CTQ-SF model was fit to measure the level of maltreatment (abuse and neglect) experience among adolescents in Indonesia

Test-retest reliability of the Childhood Trauma Questionnaire in psychotic disorders

BACKGROUND

Childhood trauma is common and associated with worse psychiatric outcomes. Yet, clinicians may not inquire about childhood trauma due to a misconception that patients cannot provide reliable reports. The goal of this study was to examine the reliability of self-reports of childhood trauma in psychotic disorders.

METHODS

We examined the test-retest reliability of the Childhood Trauma Questionnaire (CTQ) in schizophrenia (SZ, n = 19), psychotic bipolar disorder (BD, n = 17), and healthy control (HC, n = 28) participants who completed the CTQ on ≥2 occasions over variable time periods (mean 19.6 months). We calculated the intraclass correlation (ICC) for the total CTQ score, each of the five CTQ domains, and the minimization/denial subscale for the three groups. For any CTQ domains showing low test-retest reliability (ICC < 0.61), we also explored whether positive, negative, depressive, and manic symptom severity were associated with CTQ variability.

RESULTS

We found high ICC values for the total CTQ score in all three groups (SZ 0.82, BD 0.85, HC 0.88). The ICC values for CTQ subdomains were also high with the exceptions of scores for sexual abuse in BD (0.40), emotional neglect in SZ (0.60), and physical neglect in BD (0.51) and HC (0.43). In exploratory analyses, self-reports of sexual abuse in BD were associated with greater severity of depressive symptoms (β = 0.108, p = 0.004).

CONCLUSIONS

Patients with SZ and BD can provide reliable self-reports of childhood trauma, especially related to physical and emotional abuse. The presence of psychosis should not deter clinicians from asking patients about childhood trauma.

Weekly telephone mood monitoring is associated with decreased suicidality and improved sleep quality in a clinical sample

Sleep disturbances and suicidality are common presentations of mood and anxiety disorders. If not closely monitored post-discharge, patients may be at an increased risk of symptom worsening and completed suicide. We explored the associations between telephone mood monitoring, suicidality, and sleep quality in a clinical sample. Fifty inpatients (mean age = 39.49, SD = 11.17; female = 74%) with a mood and/or anxiety disorder were telephonically monitored weekly post-discharge for16 weeks for depression and mania. Suicidality and sleep quality were assessed at intake (pre-discharge), and at weeks 4, 8, 12, and 16 post-discharge. ANOVA indicated that suicidality significantly decreased, and sleep quality improved over 16 weeks. Linear regression analysis indicated that depression severity at week 1 post-discharge significantly predicted suicidality and sleep quality at week 16. Mania severity at week 1 post-discharge predicted sleep quality, but not suicidality, at week 16. Participants generally had positive experiences of the monitoring and perceived it as helpful. Monitoring of mood state, suicidality, and sleep quality post-discharge may allow for early detection of relapse when initiated at 1-week post-discharge. This is a potentially cost-effective intervention and may relieve the burden on the mental healthcare system, especially when face-to-face consultations are not possible.

Complex PTSD in Chinese Adolescents Exposed to Childhood Trauma: A Latent Profile Analysis

Although numerous studies have supported the idea that complex posttraumatic stress disorder (CPTSD) is a distinct disorder from posttraumatic stress disorder (PTSD) and demonstrated that childhood interpersonal trauma is an important risk factor for CPTSD, few studies have examined the validity of CPTSD in adolescents, especially in non-Western contexts. Moreover, the question of which form of child maltreatment plays the most important role in predicting CPTSD, and how CPTSD is associated with psychological health, physical health, and social function among adolescents, is not clear. The present study used a Chinese high school student sample with childhood trauma experiences (N = 395) to address these questions. Latent profile analysis indicated that there were four subgroups in our sample: Low symptoms (54.43%), Disturbance of self-organization (DSO, 18.99%), PTSD (15.95%), and CPTSD (10.63%). Further analysis revealed that emotional abuse was an important risk factor for CPTSD. In addition, the CPTSD class showed the highest levels of depression, anxiety, and stress, as well as the lowest levels of life satisfaction and physical health. This study revealed that CPTSD is a distinct disorder from PTSD in Chinese adolescents exposed to childhood trauma. It provides evidence that emotional abuse might be an important risk factor for CPTSD, and demonstrates that CPTSD is accompanied by serious psychological and physical consequences in adolescents. We suggest that parents and educators should focus more on adolescents' emotional needs, avoid using negative ways such as verbal violence to express love, and pay more attention to adolescents' DSO symptoms in parenting, teaching practices and clinical interventions.

Glial receptor PLXNB2 regulates schizophrenia-related stress perception via the amygdala

Stress is a trigger for the development of psychiatric disorders. However, how stress trait differs in schizophrenia patients is still unclear. Stress also induces and exacerbates immune activation in psychiatric disorders. Plexins (Plxn) and its ligands semaphorins (Sema) are important cellular receptors with plural functions in both the brain and the immune system. Recently, the role of Plxn/Sema in regulation of neuroinflammation was also noticed. Here, when investigating immune mechanisms underlying stress susceptibility in schizophrenia, we discovered the role of Plxnb2 in stress response. Patients of first-episode schizophrenia (FES) with high stress (FES-hs, n=51) and low stress (FES-ls, n=50) perception and healthy controls (HCs) (n=49) were first recruited for neuroimaging and blood bulk RNA sequencing (RNA-seq). A mouse model of chronic unpredictable stress (CUS) and intra-amygdaloid functional blocking of Plxnb2 were further explored to depict target gene functions. Compared to HCs, FES-hs patients had bigger caudate and thalamus (FDR=0.02&0.001, respectively) whereas FES-ls patients had smaller amygdala (FDR=0.002). Blood RNA-seq showed differentially expressed PLXNB2 and its ligands among patient groups and HCs (FDR<0.05~0.01). Amygdaloid size and PLXNB2 level were both negatively correlated with stress perception (p<0.01&0.05, respectively), which fully mediated the amygdaloid positive association with PLXNB2 expression (β=0.9318, 95% CI: 0.058~1.886) in FES-hs patients. In mice, Plxnb2 was enriched in astrocytes and microglia and CUS reduced its expression in astrocytes (p<0.05). Inhibition of amygdaloid Plxnb2 by its functional blocking monoclonal antibody (mAb)-102 induced mice anxiety (p<0.05), amygdaloid enlargement (p<0.05), and microglial ramification (p<0.001) compared to saline. These data suggest that PLXNB2 regulates amygdala-dependent stress responses.

Differential contributions between objective and subjective psychosis-like experiences to suicidal ideation in college students

AIM

The present study aimed to investigate the prevalence rate of objective and subjective psychosis-like experiences (PLEs) in non-help-seeking college students and to explore their differential contributions to suicidal ideation.

METHODS

First-year college students were recruited and surveyed with the Chinese version of the 16-item Prodromal Questionnaire (CPQ-16), Childhood Trauma Questionnaire (CTQ-SF), Patient Health Questionnaire-9 (PHQ-9), General Anxiety Disorder-7 (GAD-7) and Beck Scale for Suicide Ideation (BSI). The Structured Interview of Psychosis-Risk Syndromes (SIPS) was conducted in individuals with a CPQ-16 score of 9 or higher.

RESULTS

Data were available for 8367 students. Three hundred and seventy of them scored 9 or higher on the CPQ-16, suggesting potential PLEs (4.42%). Among them, 194 agreed to the SIPS screening. The PLEs were confirmed in 103 individuals who scored 1-5 on any positive symptom scales of the SIPS (objective PLEs, oPLEs). For the remaining 91 individuals, their PLEs were not confirmed by the SIPS and thus were categorized as individuals with subjective PLEs (sPLEs). In univariate logistic regression, oPLEs was associated with a two times risk of suicidal ideation compared to sPLEs (OR = 1.971, p = .029). In multivariate logistic regression when non-PLE status was set as a reference, oPLEs significantly predicted suicidal ideation (OR = 3.441, p = .011), while the sPLEs (OR = 2.277, p = .091) was no longer a significant predictor after controlling for PHQ-9, GAD-7 and CPQ-SF scores.

CONCLUSIONS

OPLEs and sPLEs have differential contributions to suicidal ideation. OPLEs seems to be associated with a higher risk of suicidal ideation and is independent of other psychopathology.

Mediating effects of parent-child relationship on the association between childhood maltreatment and depressive symptoms among adolescents

BACKGROUND

Depressive symptoms are the most common mental disorder among adolescents, and its prevalence has been increasing in recent years. Although childhood maltreatment is a contributing factor to depressive symptoms among adolescents, the underlying mechanism of how this factor causes depressive symptoms is unclear.

OBJECTIVE

This study aimed to investigate the mediating effects of parent-child relationship on the association between childhood maltreatment and depressive symptoms among adolescents and to identify how sex and only child status affect this association.

METHODS

A total of 14,500 middle school students were randomly selected from four cities (Shenzhen, Zhengzhou, Nanchang, and Guiyang) in China. A survey questionnaire was administered to collect information on childhood maltreatment, parent-child relationship, and depressive symptoms. Pearson's correlation analysis was used in analyzing the relationship, Bootstrap method was used to test the mediating effects. A moderated mediation analysis has been used to determine the moderated mediation effect.

RESULTS

Childhood maltreatment significantly negatively correlated with parent-child relationship and positively correlated with depressive symptoms (P < 0.001). The indirect effect of parent-child relationship accounted for 20.60% of the total effect between childhood maltreatment and depressive symptoms in all respondents and differed by sex (boys, 17.00%; girls, 25.23%) and only child status (only child, 15.61%; child with siblings, 23.49%). Besides, the indirect effect of the mediation model was moderated by sex and only child status.

CONCLUSIONS

Childhood maltreatment increased the risk of depressive symptoms, and this relationship was partially mediated by parent-child relationship, sex and only child status have moderated the indirect relationship. These findings showed efforts aimed at enhancing the parent-child relationship may prevent or reduce the prevalence of depressive symptoms among adolescents, especially in girls and children with siblings.

Prevalence, demographics, and cognitive dysfunction among methamphetamine-dependent individuals with childhood maltreatment

Previous studies have shown that dependent individuals (DIs) have higher rates of childhood maltreatment and poorer cognitive performance compared with healthy controls. However, little attention has been paid to the cognitive dysfunction of DIs with childhood maltreatment. The purpose of this study was to explore the cognitive deficits of maltreated methamphetamine-dependent individuals (METH-DIs) using a cross-sectional and case-control design. In addition, we aimed to examine the prevalence of childhood maltreatment and the demographic and clinical characteristics of Chinese male METH-DIs. 330 METH-DIs and 143 healthy controls were recruited and completed a detailed questionnaire on demographic and drug-related variables. Childhood abuse data were collected from the Childhood Trauma Questionnaire-Short Form (CTQ-SF). Cognitive function was assessed by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). The Beck Depression Inventory, Beck Anxiety Inventory, and Visual Analogue Scale (VAS) were used to assess the clinical state of the METH-DIs. 166 of 326 (50.9%) METH-DIs had experienced at least one type of childhood maltreatment. Maltreated METH-DIs were more likely to have a lower level of education (t₃₂₄ = 5.81, p < 0.001), a higher level of depression(t₃₂₄ = －2.68, p < 0.01), and a younger onset age of drug use (t₃₂₄ = 3.58, p < 0.01) than METH-DIs who had no experience of childhood maltreatment. Maltreated METH-DIs also performed worse on the RBANS attention score than METH-DIs who did not experience maltreatment (F_1,324 = 15.41, p < 0.001, partial η² = 0.05). Our findings revealed that some demographic and clinical variables were associated with maltreatment among METH-DIs. Moreover, attention dysfunction was found in maltreated METH-DIs, which conforms to the theory of latent vulnerability.

Childhood maltreatment and depressive symptoms among Chinese college students: A moderated mediation model of adult attachment styles and physical activity

BACKGROUND

Previous research has investigated the independent effects of childhood maltreatment, adult attachment, and physical activity, on depressive symptoms. However, explanatory mechanisms linking childhood maltreatment to current depressive symptoms are poorly understood. This study investigated the mediating role of adult attachment between childhood maltreatment and depressive symptoms among college students and explored the moderating effect of physical activity in the mediating pathway.

METHODS

The data for the present study were gathered in three waves with 6-month lags. A total of 3662 Chinese college students completed anonymous questionnaires concerning demographic variables, childhood maltreatment, and depressive symptoms in Wave 1, adult attachment and physical activity in Wave 2, and depressive symptoms in Wave 3.

RESULTS

Childhood maltreatment and adult attachment were significantly associated with depressive symptoms, identifying a mediating role of adult attachment in the relationship between childhood maltreatment and depressive symptoms, and a moderating role of physical activity between attachment anxiety and depressive symptoms in the mediating pathway.

LIMITATIONS

This study utilized self-reported questionnaires for data collection purposes, which could constitute key study limitations.

CONCLUSIONS

These findings highlight the need to consider early stress factors (childhood maltreatment), social psychological factors (adult attachment), and potential protective factors (physical activity) simultaneously when evaluating the occurrence and development of depressive symptoms.

Characteristics and Mediating Effect of Gut Microbiota With Experience of Childhood Maltreatment in Major Depressive Disorder

Gut microbiota and childhood maltreatment are closely related to depressive symptoms. This study aimed to analyze the characteristics of gut microbiota in major depressive disorder (MDD) patients with childhood maltreatment experience and explore the correlation between gut microbiota, childhood maltreatment, and depressive symptoms. A total of 37 healthy controls (HCs) and 53 patients with MDD were enrolled, including 18 MDD patients without childhood maltreatment experience and 35 MDD patients with childhood maltreatment experience. The Hamilton’s Depression Scale (HAMD-24) and Childhood Trauma Questionnaire-Short Form (CTQ-SF) were used to evaluate their depressive symptoms and childhood maltreatment experience, respectively. The composition of gut microbiota was evaluated using 16S rRNA sequencing. Spearman’s correlation analysis was used to evaluate the correlation between different gut microbiota, depressive symptoms and childhood maltreatment. The mediation analysis was used to evaluate the mediating effect of gut microbiota. In the α-diversity analysis, we found that the Simpson index and Pielou’s Evenness index differed significantly between MDD patients without childhood maltreatment experience and HCs. In the β-diversity analysis, principal coordinate analysis (PCoA) showed significant differences between MDD patients without childhood maltreatment experience, MDD patients with childhood maltreatment experience and HCs. Twenty-seven different bacteria were identified through Linear discriminant analysis effect size (LEfSe) analysis at different levels of classification. The analysis of the correlation showed that Blautia, Bifidobacterium, Bacteroides, Roseburia, and Phascolarctobacterium were significantly correlated with HAMD and CTQ-SF scores. The mediation analysis showed that childhood maltreatment had a significant direct effect on the patients’ depressive symptoms, and Blautia, Bifidobacterium, Roseburia had a significant mediating effect. The findings of this study suggested that MDD patients with childhood maltreatment experience had different gut microbiota, which might have a mediating effect on the influence of childhood maltreatment on depressive symptoms.

The Role of Childhood Trauma in Psychosis and Schizophrenia: A Systematic Review

Schizophrenia (SCZ) is a prevalent cause of disability worldwide. Distinguished mainly by psychosis, behavioral alterations could range from hallucinations to delusions. This systematic review examines evidence of a relationship between childhood trauma/adverse life events and psychosis, especially in SCZ. A methodical search provided reproducible results using these five databases: PubMed, ScienceDirect, Semantic Scholar, JSTOR, and Cochrane Library. The systematic search focused on articles published between July 2016 and July 2021. The search strategy utilized specific keywords relevant to SCZ, psychosis, and childhood trauma. The formulation of specified inclusion and exclusion criteria was necessary to ensure a comprehensive narrowed-down search, such as the inclusion of free full-text articles published or translated in English and exclusion of irrelevant subject areas. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a strategic search initially identified 741 articles; three additional articles were identified from citation searching. After relevance screening, duplicate removal, and quality appraisal, 12 studies from databases/registers and three from citation searching met the criteria proving relevance to our review with minimal evidence of bias. The final selected 15 studies included observational studies and reviews. A review of relevant data unveiled findings on childhood adversity, individual lived experiences, and their involvement in SCZ. Evidence suggests that certain neurobiological processes occur in brain after trauma. The inflammation and dysregulation from oxidative stress predispose patients to an at-risk-mental state, facilitating the progression to SCZ. This review encourages further evaluation of early trauma detection and the potential benefits of early intervention.

Associations between PTSD symptoms and other psychiatric symptoms among college students exposed to childhood sexual abuse: a network analysis

Background: Childhood sexual abuse (CSA) is one of the prevalent forms of trauma experienced during childhood and adolescence. Previous research underscores its associations with depression, anxiety, post-traumatic stress disorder (PTSD), and psychosis. Objective: This study examined symptom connections between depression, anxiety, PTSD, and psychosis while simultaneously investigating whether these connections differed by gender among CSA survivors. Methods: A large-scale, cross-sectional study among 96,218 college students was conducted in China. Participants' CSA was measured by the Childhood Trauma Questionnaire-Short Form (CTQ-SF). Participants' PTSD, psychosis, depression, and anxiety were measured by the Trauma Screening Questionnaire (TSQ), the Psychosis Screener (PS), the nine-item Patient Health Questionnaire (PHQ-9), and the 7-item Generalized Anxiety Disorder Scale (GAD-7), respectively. Network analysis was used to explore the potential associations between these symptoms and to compare the sex differences in the symptoms model. Results: Among participants who suffered from CSA, females were more likely from left-behind households, while males were more likely from households with a high annual income (P < .001, Cohen's W = 0.07). In addition, compared to male victims, female victims were more likely to report depression, anxiety, and PTSD (P < .001, Cohen's d≈0.2), while male victims were more likely to report psychosis (P < .001, Cohen's d = 0.36). Results from network estimation showed that psychosis, depression, anxiety, and PTSD symptoms were positively correlated. Moreover, psychosis had a stronger connection with PTSD symptoms, including hypervigilance, intrusive thoughts, and physiological and emotional reactivity. Conclusions: The current study explores the associations between PTSD symptoms and psychiatric symptoms among college students exposed to CSA using a network analysis approach. These crucial symptoms of PTSD may have potential connections to psychosis. Target intervention and strategy should be developed to improve mental health and quality of life among these CSA victims. Furthermore, longitudinal studies are warranted to advance our understanding of PTSD and psychosis.

The Unique Contribution of Past Bullying Experiences to the Presence of Psychosis-Like Experiences in University Students

OBJECTIVES

Both bullying and psychosis-like experiences (PLEs) have gained much attention in recent years, but their interactions are not fully unraveled. The aim of the current study was to validate the Chinese version of Bullying Scale for Adults (C-BSA), and to investigate whether past bullying experiences independently predict the presence of PLEs in university students.

METHODS

The validity and reliability of the C-BSA were determined in two independent samples. A battery of psychological inventories was also administered to assess the presence of PLEs, maltreatment history in the family, and current depression and anxiety, including the 15-item positive subscale of the community assessment of psychic experiences (CAPE-p15), the Chinese version of the Childhood Trauma Questionnaire (CTQ), Self-Rating Depression Scale (SDS), and Self-Rating Anxiety Scale (SAS).

RESULTS

In the construction sample (N = 629), a Cronbach's α of 0.921 indicated a good internal consistency of C-BSA. The exploratory factor analysis (EFA) yielded a four-factor model and a three-factor model, and both were verified by using the confirmatory factorial analysis (CFA) in the validation sample (N = 629). The total scores of C-BSA were significantly correlated with that of CTQ, CAPE-p15, SDS, and SAS. Multivariate logistic regression revealed that bullying was associated with 2.0 or 3.7 times of risk for the presence of PLEs (numbers of bullying types < = 3 or > 3, respectively) after controlling for CTQ, SDS, and SAS scores.

CONCLUSIONS

C-BSA has shown good psychometric properties in college students. The contribution of past bullying experiences to the present PLEs seems to be independent of other childhood trauma, current depression, and anxiety.

Childhood maltreatment increases the suicidal risk in Chinese schizophrenia patients

OBJECTIVES

Childhood trauma might be a modifiable risk factor among adults with serious mental illness. However, the correlation of child trauma and suicide is unclear, which were cited most frequently as the biggest challenge to schizophrenia (SCZ) patients in China. We aim to study relationships between child trauma and suicide in SCZ patients of different disease stages.

METHODS

Ninety-one participants were included and divided into two groups, namely, first-episode group (n = 46), relapsed group (n = 45). The Positive and Negative Syndrome Scale was used to evaluate the severity of psychotic symptoms. The Beck's Suicide Intent Scale and The Nurses' Global Assessment of Suicide Risk were conducted by patient self-report to assess suicide symptom. The childhood trauma questionnaire was used to estimate severity of traumatic stress experienced during childhood.

RESULTS

Childhood trauma and different dimensions of suicide were significantly higher in the relapsed group than first-episode group (P < 0.01, respectively). BMI has a significant positive relationship with recent psychosocial stress (β = 0.473, t = 3.521, P < 0.001) in first-episode group. As in relapsed group, BMI has a positive effect between severe mental illness and suicide ideation (β = 0.672, t = 5.949, P < 0.001; β = 0.909, t = 2.463, P < 0.001), Furthermore, emotional neglect presented positively related to the suicide risk and proneness to suicidal behavior (β = 0.618, t = 5.518, P < 0.001; β = 0.809, t = 5.356, P < 0.001).

CONCLUSION

Relapsed group of patients had significantly more severe childhood trauma, recent psychosocial stress, suicidal risk and proneness to suicidal behavior. BMI and emotional neglect are unique predictors for different dimensions of suicide.

Childhood trauma and depression in college students: Mediating and moderating effects of psychological resilience

PURPOSE

Not all young people who have experienced childhood abuse and neglect will become depressed or have the same degree of depression. Psychological resilience may probably lead to part of the difference according to previous studies. To observe the association between childhood abuse and neglect and depression and analyze whether psychological resilience has mediating and moderating effects on this association.

METHODS

A cross-sectional sampling with a self-report questionnaire used to measure childhood abuse and neglect, psychological resilience, and depression of college students was conducted in four universities in Hefei City, in October 2018. SPSS PROCESS was used to test the hypotheses of mediating and moderating effects.

RESULTS

Among 4034 students, 58.1% were boys and 41.9% were girls, the average age was 20.4 years (SD = 1.4). A positive association between childhood abuse and neglect and depression was found in the population, whereas negative relationships between psychological resilience and depression, and childhood abuse and neglect were observed (r = 0.251, -0.477, and -0.196, respectively, p < 0.001). For the mediating effect of psychological resilience, the 1000-sample bootstrap demonstrated that the indirect effect was statistically significant (β = 0.073, 95% CI: 0.057-0.092). For the moderating effect, R-square increased because the interaction effect was statistically significant (ΔR2 = 0.008, p < 0.001).

CONCLUSIONS

Our study supported the conclusion of previous studies that psychological resilience mediates and moderates the process of depression. Future research can further reveal the role of psychological resilience by examining different types of childhood abuse and neglect.

Evaluation on Long-Term Test-Retest Reliability of the Short-Form Childhood Trauma Questionnaire in Patients with Schizophrenia

Background

Many studies have reported an association between childhood trauma exposure and schizophrenia. Among these studies, the Short-form Childhood Trauma Questionnaire (CTQ-SF) is one of the most widely used measures of childhood trauma. However, little is known regarding the long-term reliability of the CTQ-SF, especially in patients with psychopathology.

Methods

The CTQ-SF was administered to 50 patients diagnosed with schizophrenia from a hospital in Changsha, Hunan, China. These patients were asked to re-complete the CTQ-SF when they were re-hospitalized or received outpatient treatments in the same hospital within 4 years of follow-up. Intraclass correlation coefficient (ICC) was used to assess test–retest reliability of the CTQ-SF over the intervals. Associations of the CTQ-SF with the Positive and Negative Syndrome Scale (PANSS) and Wechsler Adult Intelligence Scale (WAIS) were tested using Spearman correlation coefficients.

Results

Among the participants, 35 (70.0%) patients re-completed the CTQ-SF after an interval averaging 11.26 months. Excellent test–retest reliabilities (with ICC > 0.75) were found for the total CTQ-SF score (ICC = 0.772) as well as scores of the emotional abuse (ICC = 0.808), physical abuse (ICC = 0.756), sexual abuse (ICC = 0.877) and physical neglect (ICC = 0.751) subscales. Meanwhile, a moderate test–retest reliability was found for the emotional neglect subscale (ICC = 0.538). At both baseline and follow-up, no significant correlations (p > 0.05) were found between CTQ-SF scores and any other clinical assessments.

Conclusion

Our results suggest that CTQ-SF is reliable to assess childhood trauma exposures in schizophrenia over relatively long intervals, regardless of patients’ current symptoms and states of cognition.

Associations Between Childhood Trauma and the Age of First-Time Drug Use in Methamphetamine-Dependent Patients

Childhood trauma is related to substance use disorder; however, few studies have examined the relationship between childhood trauma and the age at which the drug was first used. The aim of this study was to investigate the relationship between childhood trauma and the age of first-time drug use among methamphetamine-dependent patients. Moreover, we analyzed the characteristics of adverse family environment associated with severe childhood trauma and the risk factors for starting drugs in minors. A baseline interview was conducted with 110 participants who were in detoxification, including demographic information, past substance use, and age of first-time drug use. The participants' childhood trauma experience before 18 years of age was evaluated using the simplified version of the Childhood Trauma Questionnaire (CTQ-SF). The Chinese version of the Family Environment Scale (FES-CV) was used to assess the family environment of methamphetamine-dependent patients. Among 110 non-injecting methamphetamine-dependent patients, nearly half (n = 48, 43.6%) had moderate and severe childhood trauma. Correlation analysis showed that the age of first-time drug use negatively correlated with emotional abuse (r = -0.32, p < 0.01) and physical abuse (r = -0.27, p < 0.01). The age of first-time drug use negatively correlated with conflict (r = -0.20, p < 0.05) and independence (r = -0.22, p < 0.05) of family environment, but positively correlated with intellectual-cultural orientation (r = 0.28, p < 0.01). Additionally, childhood trauma factors significantly correlated with many indexes of family environment, especially cohesion (r = -0.45, p < 0.01), conflict (r = 0.49, p < 0.01), and independence (r = 0.33, p < 0.01). Additionally, the regression model showed that when emotional abuse increased by one point, the age of first-time drug use was 0.69 years earlier. These findings suggest that a detrimental family environment can aggravate childhood trauma, and the experience of childhood emotional or physical abuse may be an effective predictor of early drug use among methamphetamine-dependent patients.

The Role of Military Training in Improving Psychological Resilience and Reducing Depression Among College Freshmen

Background: Military training plays an important protective role in enhancing mental health. However, the effects of military training on psychological resilience and depression among college freshmen in China remain unclear. The present study aimed to evaluate changes in psychological resilience and depression through military training among college freshmen, and to investigate associated psychosocial factors including childhood trauma that may influence its effects on psychological resilience. Methods: A prospective and self-comparison study design was employed. College freshmen who received 3 weeks of military training were recruited. Socio-demographic variables were collected and childhood trauma exposure was estimated by the Childhood Trauma Questionnaire (CTQ). The Connor-Davidson Resilience Scale (CD-RISC) and Patient Health Questionnaire (PHQ-9) were used to assess psychological resilience and depression before and after the military-style training. Results: The military training significantly increased the total and subscale scores of CD-RISC (p < 0.001), and decreased the PHQ-9 score (p < 0.001). The proportion of students with clinical depression reduced from 10.5% at baseline to 7.2% after the training (p < 0.001). Improvement of CD-RISC scores was positively affected by male gender and urban area, while negatively affected by older age, and higher baseline scores of PHQ-9 and CTQ. A significant correlation was found between changes in scores of CD-RISC and PHQ-9 through the training (r = -0.238, p < 0.001). Conclusions: Military training may have a positive effect on increasing psychological resilience and reducing depressive symptoms among college freshmen, especially in male students and those from an urban area, while older age, childhood trauma, higher depression levels, and resilience at baseline may weaken, or even mask its positive effect. Follow-up research should be considered for the long-term effects of military-style training.
