[PMID: 38695042 PMCID: PMC11065524 DOI: 10.30773/pi.2023.0188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 10/19/2023] [Accepted: 01/01/2024] [Indexed: 05/04/2024] Open
Abstract
OBJECTIVE Although previous studies have validated the effect of childhood trauma on depressive level, few studies have utilized the diathesis-stress theory to investigate the specific roles of perceived stress and rumination in the pathway between childhood trauma and depression in Chinese college students. This study aims to demonstrate the mediation effect of perceived stress and the moderation effect of rumination in the pathway between childhood trauma and depressive level in Chinese college students. METHODS A total of 995 Chinese college students in Guangzhou were included in this study by recruitment advertisement from October to December 2021. And they were asked to finish four self-report questionnaires, including Childhood Trauma Questionnaire-Short Form, Perceived Stress Scale, the 22-item Ruminative Response Scale, and Beck Depression Scale-II. Then the data were analyzed with Mplus 8.3. RESULTS Results revealed significant correlations among childhood trauma, perceived stress, rumination and depressive level. Further analyses revealed that perceived stress played a mediation role between childhood trauma and depressive level (estimate=0.09, standard error [SE]=0.02, t=5.93, 95% confidence interval [CI]=0.06-0.12), and rumination played a moderation role between childhood trauma and perceived stress (estimate=-0.17, SE=0.06, t=-2.86, 95% CI=-0.28- -0.05]) as well as between childhood trauma and depressive level (estimate=0.10, SE=0.04, t=2.74, 95% CI=0.03-0.16). CONCLUSION These results revealed the mediation effect of perceived stress and the moderation effect of rumination in the pathway between childhood trauma and depressive level in Chinese college students, which helped us to understand how the childhood trauma influenced the depressive level and gave us multi-dimensional indications for reducing the effect of childhood trauma on depressive level.

Abstract
BACKGROUND Affective lability is an important feature of psychopathology. However, there is limited relevant research involving adolescents. To fill this research gap, the present study assessed the relationship between childhood trauma and affective lability among adolescents using a moderated mediation model. METHODS A total of 3738 students were recruited from four high schools in Shenzhen, China, between September and December 2019. The participants completed self-reported questionnaires measuring childhood trauma, affective lability, body image dissatisfaction, and the experience of being bullied. Linear regression and moderated mediation analyses were used in this study. RESULTS Linear regression analysis showed that emotional abuse and body image dissatisfaction positively predicted affective lability in boys and girls (all p < 0.001). Body image dissatisfaction mediated the relationship between emotional abuse and affective lability. In the moderated mediation model, being bullied moderated the direct path from emotional abuse to affective lability (p = 0.0236, p = 0.0188), and gender did not have a significant moderating effect on any direct or indirect path (all p > 0.05). LIMITATIONS A causal relationship could not be ascertained due to the cross-sectional design, and the results cannot be generalized to other populations. CONCLUSIONS The findings support that childhood trauma has an impact on affective lability in adolescents. Specifically, body image dissatisfaction and being bullied affect the relationship between emotional abuse and affective lability.

Abstract
AIMS AND METHOD We aimed to examine the burden of mental disorders in Pakistan over the past three decades. We used the crude data of disability-adjusted life-years (DALYs) obtained from the Global Burden of Disease Study database (1990-2019) to represent burden. Data were retrieved on 26 January 2021. Data for adults of reproductive age (aged 15-49 years) were analysed to discuss and interpret the disease burden. An analysis was conducted on total DALYs separately for the genders for ten mental disorders reported in Pakistan. RESULTS DALYs increased drastically with the onset of reproductive age. Depressive disorder was the most reported mental disorder, contributing 3.13% (95% CI 2.25-4.24) of total DALYs, and varied significantly between genders: females 3.89% (95% CI 2.73-5.29) versus males 2.37% (95% CI 1.62-3.25). CLINICAL IMPLICATIONS A nationwide high-quality epidemiological surveillance system should be implemented to monitor mental disorders and offer culturally appropriate preventive services.

Abstract
OBJECTIVES Childhood maltreatment, cognitive emotion regulation strategies (CERSs), and depression can be important in adolescents' Internet addiction. The current study aims to investigate the direct effect of childhood maltreatment on Internet addiction and its indirect effects via CERSs and depression. PARTICIPANTS AND SETTING 4091 adolescents (age M = 13.64, SD = 1.59; 48.9 % males) were recruited from a public school in China. METHODS In a cross-sectional design, participants completed the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Cognitive Emotion Regulation Questionnaire-Short version (CERQ-Short), the Self-Rating Depression Scale (SDS), and the Internet Addiction Test (IAT). A latent structural equation model was used to test the hypotheses. RESULTS After controlling for age, childhood maltreatment was directly associated with adolescents' Internet addiction (β = 0.12, p < 0.001). Meanwhile, the serial mediating effect via maladaptive CERSs and depression was 0.02 (95 % CI [0.01, 0.04]), and via adaptive CERSs and depression was 0.001 (95 % CI [0.0004, 0.002]), demonstrating significant serial mediating role of CERSs and depression in this relationship. No gender difference was observed. CONCLUSIONS The findings suggest that maladaptive CERSs and depression can be potential mechanisms relating childhood maltreatment to adolescents' Internet addiction, while adaptive CERSs can be a less influential factor for reducing Internet addiction.

Abstract
OBJECTIVES Depression, alcohol use, and alcohol-related consequences are experienced disproportionately by American Indian (AI) adolescents. The co-occurrence of depression and alcohol use is clinically relevant, as it is associated with increased risk for suicide, among other negative consequences. Understanding how the association between depressive symptoms and alcohol use and related consequences is influenced by gender is important to understand for whom intervention efforts might be particularly relevant. Thus, the present study seeks to evaluate gender differences in these associations among AI adolescents. METHODS Participants were a representative sample of AI adolescents (N = 3,498, Mage=14.76, 47.8% female) residing on or near reservations who completed self-report questionnaires in school classrooms. Study activities were approved by IRB, school boards, and tribal authorities. RESULTS The interaction of depressive symptoms and gender was significant in predicting past-year alcohol use frequency (b=.02, p=.02) and, among youth reporting lifetime alcohol use, alcohol-related consequences (b=.03, p=.001). Analysis of simple slopes revealed that, for females, depressive symptoms were significantly associated with past-year alcohol use frequency (b=.02, p<.001) and alcohol-related consequences (b=.05, p<.001). For males, depressive symptoms were only significantly associated with alcohol-related consequences (b=.02, p=.04), and this effect was weaker than for females. CONCLUSIONS Results of the present study may inform the development of gender-sensitive recommendations for the assessment and treatment of alcohol use and alcohol-related consequences among AI adolescents. For instance, results suggest that treatments focusing on depressive symptoms may subsequently reduce alcohol use and related consequences for female AI adolescents.

Abstract
IMPORTANCE Immune-metabolic disturbances have been implicated in the pathophysiology of major depressive disorder and may be more prominent in individuals with treatment-resistant depression (TRD). Preliminary trials suggest that lipid-lowering agents, including statins, may be useful adjunctive treatments for major depressive disorder. However, no adequately powered clinical trials have assessed the antidepressant efficacy of these agents in TRD. OBJECTIVE To assess the efficacy and tolerability of adjunctive simvastatin compared with placebo for reduction of depressive symptoms in TRD. DESIGN, SETTING, AND PARTICIPANTS This 12-week, double-blind, placebo-controlled randomized clinical trial was conducted in 5 centers in Pakistan. The study involved adults (aged 18-75 years) with a Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) major depressive episode that had failed to respond to at least 2 adequate trials of antidepressants. Participants were enrolled between March 1, 2019, and February 28, 2021; statistical analysis was performed from February 1 to June 15, 2022, using mixed models. INTERVENTION Participants were randomized to receive standard care plus 20 mg/d of simvastatin or placebo. MAIN OUTCOMES AND MEASURES The primary outcome was the difference between the 2 groups in change in Montgomery-Åsberg Depression Rating Scale total scores at week 12. Secondary outcomes included changes in scores on the 24-item Hamilton Rating Scale for Depression, the Clinical Global Impression scale, and the 7-item Generalized Anxiety Disorder scale and change in body mass index from baseline to week 12. C-reactive protein and plasma lipids were measured at baseline and week 12. RESULTS A total of 150 participants were randomized to simvastatin (n = 77; median [IQR] age, 40 [30-45] years; 43 [56%] female) or placebo (n = 73; median [IQR] age, 35 [31-41] years; 40 [55%] female). A significant baseline to end point reduction in Montgomery-Åsberg Depression Rating Scale total score was observed in both groups and did not differ significantly between groups (estimated mean difference for simvastatin vs placebo, -0.61; 95% CI, -3.69 to 2.46; P = .70). Similarly, there were no significant group differences in any of the secondary outcomes or evidence for differences in adverse effects between groups. A planned secondary analysis indicated that changes in plasma C-reactive protein and lipids from baseline to end point did not mediate response to simvastatin. CONCLUSIONS AND RELEVANCE In this randomized clinical trial, simvastatin provided no additional therapeutic benefit for depressive symptoms in TRD compared with standard care.

Abstract
BACKGROUND Childhood trauma is negatively associated with depression severity in bipolar disorder; however, the underlying mechanisms remain unclear. We investigated whether personality traits (neuroticism, extraversion, openness, agreeableness, conscientiousness) mediate the relationship between childhood trauma and the severity of bipolar depression. METHODS Data from 209 individuals with bipolar disorder recruited for the Prechter Longitudinal Study of Bipolar Disorder were analysed. Using structural equation modelling, we examined the direct and indirect associations between childhood trauma (Childhood Trauma Questionnaire) and depression severity (Hamilton Depression Rating Scale) - with the personality traits (NEO Personality Inventory-Revised) as mediators. RESULTS The direct effect of childhood trauma on depression severity (standardised β = 0.32, 95% bootstrap confidence interval [CI] = 0.20-0.45, p < 0.001) and the indirect effect via neuroticism (standardised β = 0.03, 95% bootstrap CI [0.002, 0.07], p = 0.039) were significant; supporting a partial mediation model. The indirect effect accounted for 9% of the total effect of childhood trauma on depression severity (standardised β = 0.09, 95% bootstrap CI [0.002, 0.19], p = 0.046). The final model had a good fit with the data (comparative fit index = 0.96; root mean square error of approximation = 0.05, 90% CI = [0.02, 0.07]). CONCLUSION Personality traits may be relevant psychological mediators that link childhood trauma to a more severe clinical presentation of bipolar depression. Consequently, a person's personality structure may be a crucial operative factor to incorporate in therapeutic plans when treating individuals with bipolar disorder who report a history of childhood trauma.

Abstract
BACKGROUND Patients with major depressive disorders (MDD) have abnormalities in the frontal-limbic structures of the brain. Childhood trauma is a risk factor for both structural brain alterations and MDD. However, the relationships among the three have not been confirmed. METHODS Sixty-four patients with MDD and sixty-one healthy controls (HC) were checked by using MRI, the Hamilton Depression Scale (HAMD) and Childhood Trauma Questionnaire (CTQ). Voxel-based morphometry (VBM) was used to compare gray matter volume (GMV) differences between the two groups. Moreover, partial correlation and mediation analyses were conducted to test for potential associations between CTQ scores, different GMV, and clinical variables. RESULTS Compared to the HC group, the MDD patients showed decreased GMV in the right middle frontal gyrus (rMFG) and right precentral gyrus (rPreCG). In the patient group, reduced GMV in rMFG was associated with CTQ scores (r = -0.30, P = 0.019) and HAMD scores (r = -0.53, P < 0.001). Finally, in the patient group, mediation analysis revealed that the indirect effect of rMFG GMV in CTQ scores and HAMD scores was 0.115 and the proportion of indirect effect to total effect was 23.86%. LIMITATIONS This study used a cross-sectional collection, and it is unclear whether at the longitudinal level the brain GMV mediates the relationship between childhood trauma and depression. CONCLUSIONS Abnormalities in the frontal GMV were presented in the MDD patients. It is possible that childhood traumatic experiences cause inefficient GMV and ultimately lead to an increased susceptibility to depression.

Abstract
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.

Silva M, Pereira H. The Impact of Life Trauma on Mental Health and Suicidal Behavior: A Study from Portuguese Language Countries. Behav Sci (Basel) 2022; 12:bs12040102. [PMID: 35447674 PMCID: PMC9031010 DOI: 10.3390/bs12040102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Revised: 04/02/2022] [Accepted: 04/08/2022] [Indexed: 02/05/2023] Open
Abstract
Several studies report the incidence of traumatic experiences in community and clinical samples, and substantial research demonstrates the impact of traumatic events on mental health and suicidal behavior, but this area remains unexplored in the Community of Portuguese Language Countries (CPLC). Thus, this study aims to (1) describe traumatic experiences, mental health levels and suicidal behavior among individuals from Portugal, Brazil and African Countries with Portuguese as an Official Language (ACPOL); (2) assess correlations between traumatic experiences and mental health and suicidal behavior; and (3) assess the impact of exposure to a traumatic event on mental health and suicidal behavior. The measurement instruments included a sociodemographic questionnaire, Brief Trauma Questionnaire, Brief Symptoms Inventory-18, and the Portuguese version of the Suicidal Behaviors Questionnaire-Revised. ACPOL participants reported greater impact of war, Portuguese participants reported greater impact of disasters, and Brazilian participants reported greater impact of psychological and sexual abuse, assault, and death of a family member. Brazilian participants showed the worst levels of mental health and suicidal thoughts. Strong correlations were found between traumatic experiences and mental health levels and suicidal behavior. Traumatic experiences contributed to the explanation of mental health levels and probability of committing suicide.
