Cumulative Exposure to Adverse Childhood Experience: Depressive Symptoms, Suicide Intensions and Suicide Plans among Senior High School Students in Nanchang City of China

Exploring the mediating role of self-hate in the relationship between adverse childhood experiences and non-suicidal self-injury among adolescents

BACKGROUND

Non-suicidal self-injury (NSSI) has become a serious global problem among adolescents. This study aimed to explore the relationships between adverse childhood experiences, self-hate, and non-suicidal self-injury in adolescents.

METHODS

A total of 7009 adolescents participated in a survey from August 1 to December 31, 2023. The survey comprised the revised Adverse Childhood Experience (ACE) Questionnaire, Self-Hate Scale, and Adolescent Non-Suicidal Self-Injury Assessment Questionnaire. SPSS 22.0 was utilized for data entry and analysis. Spearman's correlation analysis was employed to examine the relationships between the variables. The bias-corrected nonparametric percentile bootstrap method was used to test the significance of the mediating effect.

RESULTS

Adverse childhood experiences, self-hate, and non-suicidal self-injury were positively correlated. Adverse childhood experiences directly affected self-injury without obvious tissue damage. Self-hate mediated the relationship between adverse childhood experiences and self-injury without obvious tissue damage. Adverse childhood experiences directly affected self-injury with obvious tissue damage. Self-hate mediated between adverse childhood experiences and self-injury with obvious tissue damage.

LIMITATIONS

The data were cross-sectional, and the effects of adverse childhood experiences were not immediate. Further, because this was a subjective study, reporting bias was inevitable. Finally, future research should expand the discussion and improve the global relevance of the study.

CONCLUSION

Self-hate mediates the relationship between adverse childhood experiences and NSSI in adolescents. This study explores the underlying mechanisms and influencing factors of NSSI in adolescents and provides important evidence-based support for the prevention and intervention of NSSI in adolescents with different characteristics to maintain adolescents' physical and mental health.

IMPLICATIONS AND CONTRIBUTION

Given the close relationships found between adverse childhood experiences, self-hate, and non-suicidal self-injury (NSSI) in adolescents, it is crucial to address adverse childhood experiences to prevent and treat NSSI. Providing necessary psychological support and interventions can help foster positive self-awareness, enhance self-esteem and self-efficacy, reduce self-disgust, and mitigate the negative effects of adverse childhood experiences.

The impact of adverse childhood experiences on postpartum post-traumatic stress disorder in women: A prospective cohort study in China

BACKGROUND

Women are more prone to experience adverse childhood experiences (ACEs), placing them at higher risk of postpartum mental health disorders. However, research on ACEs, particularly their association with postpartum Post-Traumatic Stress Disorder (PTSD) in non-Western contexts, is limited.

OBJECTIVE

To utilize a cumulative risk approach and latent class analysis (LCA) to operationalize ACEs among postpartum women in China and examine their association with postpartum PTSD.

METHODS

In this prospective cohort study, 856 eligible participants from a tertiary hospital in Guangdong province of China between October 2022 and August 2023 completed assessments of demographic and obstetric characteristics, and ACEs within 2-3 days postpartum, followed by PTSD evaluation at 42 days postpartum. The cumulative risk approach and LCA were employed to operationalize ACEs, and their association with postpartum PTSD was assessed using log-binomial regression models, adjusting for potential confounders.

RESULTS

Among the participants, 80.4 % (688/856) reported ACEs, with 18.2 % experiencing four or more ACEs, a threshold above which there was a particularly higher risk of postpartum PTSD in the adjusted model (OR = 8.27, 95 % CI = 3.08-22.20). LCA identified three groups: low ACEs, household and community violence, and multiple ACEs, with women in the multiple ACEs group exhibiting the most severe postpartum PTSD symptoms in the adjusted model (OR = 4.39, 95 % CI = 1.58-12.24).

CONCLUSIONS

This study demonstrates that ACEs are a significant risk factor for postpartum PTSD, especially for women who have experienced four or more ACEs, or multiple ACEs, placing them at particularly high risk for developing postpartum PTSD.

Patterns of adverse childhood experiences and their associations with depression, life satisfaction and short-form video addiction in Chinese college students

BACKGROUND

Adverse childhood experiences (ACEs) are widespread in East Asia, heightening the susceptibility to psychological and behavioral complications in adulthood.

OBJECTIVE

To identify polyvictimization patterns among Chinese college students and investigate the associations between diverse patterns and symptoms of depression, short-form video addiction (SVA), and life satisfaction.

PARTICIPANTS AND SETTING

This study encompassed 13,307 college students from four urban centers in China (Mage = 20.2; 46.4 % female).

METHODS

Latent class analysis (LCA) was employed to discern patterns of ACEs among college students. The three-step method (R3step) was utilized to explore the influence of demographic characteristics on the distribution of latent classes. Additionally, the automatic Bolck-Croon-Hagenaars (BCH) Method was deployed to investigate the latent classes effect on distal outcomes.

RESULTS

Left-behind experience was the most common ACE among Chinese college students. Four ACEs patterns were identified: 1) No/Very Low ACEs class (N = 8936, 67.2 %); 2) Parental Absence class (N = 430, 3.2 %); 3) Low/Moderate ACEs class (N = 3565, 26.8 %); and 4) High Violence and Left-behind class (N = 376, 2.8 %). The findings revealed a progressive escalation in healthy outcomes associated with the four ACEs patterns. Specifically, from the first class to the fourth, the severity of associated consequences (depression, life satisfaction and SVA) intensified.

CONCLUSIONS

Distinct ACEs patterns correlate with varying degrees of mental health issues. Compared to participants solely separated from parents, those exposed to abuse and neglect demonstrate more pronounced mental health challenges and addiction susceptibilities.

Adverse childhood experiences and depressive symptoms among lesbian and bisexual women in China

BACKGROUND

Despite the relationship between Adverse childhood experiences (ACEs) and depressive symptoms, which has been well researched in general populations, little is known about homosexual and bisexual populations, especially lesbian and bisexual women in China. This study aims to investigate the prevalence of ACEs and depressive symptoms and to analyze the relationship between them among lesbian and bisexual women in China.

METHODS

The eligible participants were aged 16 years or older who report their sexual orientation as homosexual or bisexual. The data was collected through anonymous questionnaires with the help of Lespark in Beijing from July 18 to December 29, 2018, and all participants had informed consent to this study. Univariate analysis and multiple linear regression analyses were performed to explore the relationship between ACEs and depressive symptoms among lesbian and bisexual women. All statistical analyses were conducted by the software of SPSS 22.0.

RESULTS

Among 301 lesbian and bisexual women, 81.4% were lesbian, 18.4% were bisexual women, and the majority were 21-30 years. As for ACEs, 51.5% reported at least one ACE, in which emotional neglect (22.6%) and emotional abuse (22.3%) were common ACEs. As for depressive symptoms of lesbian and bisexual women, the detection rate was 56.1%. The multiple linear regression analyses showed that abuse (β = 2.95, 95%CI:1.07-4.83) and neglect (β = 3.21, 95%CI:1.09-5.31) were positively associated with depressive symptoms and lesbian and bisexual women with three (β = 4.11, 95%CI: 0.99-7.22) or more (β = 6.02, 95%CI: 3.23-8.78) ACEs suffered from more depressive symptoms than others.

CONCLUSION

Adverse childhood experiences (ACEs) and depressive symptoms were at high prevalence among lesbian and bisexual women in China. ACEs were associated with depressive symptoms, especially childhood abuse and neglect experiences that have a significant effect on lesbian and bisexual women mental health.

Interpersonal Well-Being and Suicidal Outcomes in a Nationally Representative Study of Adolescents: A Translational Study

Adolescent suicide continues to rise despite burgeoning research on interpersonal risk for suicide. This may reflect challenges in applying developmental psychopathology research into clinical settings. In response, the present study used a translational analytic plan to examine indices of social well-being most accurate and statistically fair for indexing adolescent suicide. Data from the National Comorbidity Survey Replication Adolescent Supplement were used. Adolescents aged 13-17 (N = 9,900) completed surveys on traumatic events, current relationships, and suicidal thoughts and attempts. Both frequentist (e.g., receiver operating characteristics) and Bayesian (e.g., Diagnostic Likelihood Ratios; DLRs) techniques provided insight into classification, calibration, and statistical fairness. Final algorithms were compared to a machine learning-informed algorithm. Overall, parental care and family cohesion best classified suicidal ideation, while these indices and school engagement best classified attempts. Multi-indicator algorithms suggested adolescents at high risk across these indices were approximately 3-times more likely to engage in ideation (DLR = 3.26) and 5-times more likely to engage in attempts (DLR = 4.53). Although equitable for attempts, models for ideation underperformed in non-White adolescents. Supplemental, machine learning-informed algorithms performed similarly, suggesting non-linear and interactive effects did not improve model performance. Future directions for interpersonal theories for suicide are discussed and clinical implications for suicide screening are demonstrated.

Examining the relationship between risky sexual behavior and suicidal thoughts among unmarried adolescents in India

Addressing the problem of suicidal thoughts in adolescents requires understanding the associated risk factors. Multiple studies have shown that risky sexual behavior affected the adolescents' psychological health that leads to their suicidal thoughts, behaviors and attempts. This study aimed to identify the association between various risky sexual behaviours and suicidal thoughts among unmarried adolescents in India. We used data collected from 4221 unmarried adolescent boys and 5987 unmarried adolescent girls aged 10-19 years, from the two rounds of the Understanding the Lives of Adolescents and Young Adults (UDAYA) survey. Descriptive analysis was done to observe changes in the selected variables from wave-1 to wave-2. Random effect regression analysis was used to estimate the association of suicidal thoughts among unmarried adolescents with their risky sexual behaviours. The percentage of adolescent boys having suicidal thoughts increased from 1.35% in wave 1 to 2.19% in wave 2. Among adolescent girls, the percentage increased from 2.92% in wave 1 to 5.05% in wave 2. A proportion of 3.26% adolescent boys had more than one sexual partner during wave 1 whereas in wave 2, it rose to 8.71%, while in case of adolescent girls, the estimates only increased from 0.26% at wave 1 to 0.78% at wave 2. Nearly 4.55% boys and 1.37% girls had early sexual debut. Almost five percentage boys were sexually active at wave 1 whereas in wave 2, it rose to 13.56%, while among adolescent girls, the estimates decreased from 1.54% at wave 1 to 1.51% at wave 2. Contraceptive use increased over time among both adolescent boy and girls. Also, a large proportion of adolescent boys reported watching pornography (27.08% at waive 1 and 49.39% at wave 2) compared to adolescent girls (4.46% at wave 1 and 13.10% at wave 2). Adolescents who had more than one sexual partner [Coef: 0.04; p < 0.001], exposed to early sexual debut [Coef; 0.019; p < 0.01], sexually active [Coef: 0.058; p < 0.001] and reported watching pornography [Coef: 0.017; p < 0.001] were more likely to have suicidal thoughts. Adolescent boys and girls with risky sexual behaviors are likely to be at a higher risk of suicidal ideation, and thus, they should be treated with special care and attention by local healthcare practitioners.

Dissecting early life stress-induced adolescent depression through epigenomic approach

Early life stress (ELS), such as abuse and neglect during childhood, can lead to psychiatric disorders in later life. Previous studies have suggested that ELS can cause profound changes in gene expression through epigenetic mechanisms, which can lead to psychiatric disorders in adulthood; however, studies on epigenetic modifications associated with ELS and psychiatric disorders in adolescents are limited. Moreover, how these epigenetic modifications can lead to psychiatric disorders in adolescents is not fully understood. Commonly, DNA methylation, histone modification, and the regulation of noncoding RNAs have been attributed to the reprogramming of epigenetic profiling associated with ELS. Although only a few studies have attempted to examine epigenetic modifications in adolescents with ELS, existing evidence suggests that there are commonalities and differences in epigenetic profiling between adolescents and adults. In addition, epigenetic modifications are sex-dependent and are influenced by the type of ELS. In this review, we have critically evaluated the current evidence on epigenetic modifications in adolescents with ELS, particularly DNA methylation and the expression of microRNAs in both preclinical models and humans. We have also clarified the impact of ELS on psychiatric disorders in adolescents to predict the development of neuropsychiatric disorders and to prevent and recover these disorders through personalized medicine.

Examining Childhood Adversities in Chinese Health Science Students Using the Simplified Chinese Version of the Adverse Childhood Experiences-International Questionnaire (SC-ACE-IQ)

Adverse childhood experiences (ACEs) are prevalent, costly, and associated with poor health outcomes in adults. Little is known about ACE prevalence rates or strategies for measuring ACEs among young adults in Mainland China. The aims of this study were to (a) translate the ACE-International Questionnaire (ACE-IQ) into Simplified Chinese, (b) assess the psychometric strength of the Simplified Chinese version of the ACE-IQ (SC-ACE-IQ), and (c) compare SC-ACE-IQ scores calculated using binary and frequency scoring methods. The ACE-IQ was translated from English to Simplified Chinese and evaluated for content validity, criterion validity, and test–retest reliability. Chinese young adults (n = 566) aged 18–38 years who were health science students were recruited in Shanghai, China from May to August 2020. ACE exposures were compared using binary and frequency scoring methods, as proposed by the World Health Organization (WHO). The SC-ACE-IQ has good content validity (S-CVI = 0.89) and test–retest reliability (ICC = 0.88). SC-ACE-IQ scores were associated with depressive (binary: r = 0.26, frequency: r = 0.29; p < 0.001) and anxiety (binary: r = 0.22, frequency: r = 0.24; p < 0.001) symptoms. Higher proportion of participants reported exposure to at least one ACE and four or more ACEs when using the binary scoring method compared to the frequency scoring method. The SC-ACE-IQ is a valid and reliable ACE measure for Chinese health science students. Using frequency methods may underestimate exposure to ACEs among this population. Researchers should carefully select scoring methods for different study populations and purposes.

Higher exposure to childhood adversity associates with lower adult flourishing

BACKGROUND

Adverse childhood experiences (ACEs) are prevalent and associated with negative health and social outcomes. However, our understanding of how patterns of ACEs exposure relate to positive outcomes in adulthood remains limited. This study aims to identify patterns of ACEs and examine associations with flourishing in a sample of Chinese young adults.

METHODS

This cross-sectional study was conducted from August to November 2020. Young adults, ages 18-35, enrolled in undergraduate or graduate programs at universities in Mainland China were recruited through convenience and snowball sampling to participate in a survey. The exposure to ACEs was measured by the twelve-item Chinese version of the ACE-International Questionnaire. Additional measures included six domains of flourishing assessed using the Chinese version of the Flourishing Measure, and demographic covariates (i.e., gender, age, year in university, marital status). Descriptive statistical analysis and latent class analysis (LCA) were performed using SPSS 27 and Mplus 8.5.

RESULTS

Participants included 9468 young adults (mean age = 20.1 years). Majority of participants were female (75.3%), undergraduate students (96.4%), and single (79.8%). Approximately 56% of participants reported at least one ACE; 7.0% reported four or more ACEs. Emotional neglect (33.2%), household violence (20.6%), and parental separation/divorce (13.9%) were the most frequently reported ACEs. LCA identified three ACEs classes: multiple maltreatment and household violence (4.7%), emotional neglect and household violence (16.2%), and low ACEs (79.1%). Individuals in the low ACEs class had the highest level of flourishing whereas individuals in multiple maltreatment and household violence had the lowest level of flourishing in all six domains. There were no significant differences in flourishing between the multiple maltreatment and household violence and the emotional neglect and household violence classes except in the physical and mental health (means = 6.17 vs 6.51, p = 0.02) and the financial and material stability domains (means = 5.25 vs 5.66, p = 0.04).

CONCLUSIONS

Patterns of multiple ACEs exposures were associated with lower levels of flourishing. Our findings have implications for efforts to prevent ACEs exposure through monitoring and promoting family well-being and routine screening to identify those with ACEs exposure to prevent negative social and health sequelae.

Childhood Experiences and Psychological Distress: Can Benevolent Childhood Experiences Counteract the Negative Effects of Adverse Childhood Experiences?

Background

Childhood experiences can exert a huge impact on adult psychological conditions. Previous studies have confirmed the effects of adverse childhood experiences (ACEs) and benevolent childhood experiences (BCEs) on psychological distress (e.g., stress, depression, and suicidal ideation) separately, but few studies explored a combined effect of ACEs and BCEs on psychological distress. The aim of this study was to explore a combined effect of ACEs and BCEs on psychological distress among Chinese undergraduates.

Methods

Participants were undergraduates aged 17–24 years (N = 1,816) and completed a self-reported questionnaire. A series of regression analyses were conducted to examine the association between childhood experiences and psychological distress.

Results

A total of 65.7% of undergraduates had BCEs, 27.1% of undergraduates had ACEs, and 12.9% of undergraduates had ACEs and BCEs simultaneously. Logistic regression analysis indicated that undergraduates who experienced high ACEs were more likely to have a high risk of psychological distress [odds ratio (ORs) = 1.46, 1.84, and 3.15 for uncertainty stress, depressive symptoms, and suicidal ideation, respectively], while undergraduates who experienced High BCEs were less likely to have psychological distress (ORs = 0.33, 0.22, and 0.32 for uncertainty stress, depressive symptoms, and suicidal ideation, respectively) compared with Low-Both group. The combined effect of ACEs and BCEs (High-Both group) could also play as a protective factor in uncertainty stress (OR = 0.56) and depressive symptoms (OR = 0.47).

Conclusion

Our findings suggested that ACEs and BCEs could not only predict the psychological distress independently, but also BCEs could counteract the negative effect of ACEs in psychological problems. There is an even greater need to identify and support the victims of ACEs and to increase BCEs in early childhood.

Multiomic biological approaches to the study of child abuse and neglect

Childhood maltreatment, occurring in up to 20-30% of the population, remains far too common, and incorporates a range of active and passive factors, from abuse, to neglect, to the impacts of broader structural and systemic adversity. Despite the effects of childhood maltreatment and adversity on a wide range of adult physical and psychological negative outcomes, not all individuals respond similarly. Understanding the differential biological mechanisms contributing to risk vs. resilience in the face of developmental adversity is critical to improving preventions, treatments, and policy recommendations. This review begins by providing an overview of childhood abuse, neglect, maltreatment, threat, and toxic stress, and the effects of these forms of adversity on the developing body, brain, and behavior. It then examines examples from the current literature of genomic, epigenomic, transcriptomic, and proteomic discoveries and biomarkers that may help to understand risk and resilience in the aftermath of trauma, predictors of traumatic exposure risk, and potential targets for intervention and prevention. While the majority of genetic, epigenetic, and gene expression analyses to date have focused on targeted genes and hypotheses, large-scale consortia are now well-positioned to better understand interactions of environment and biology with much more statistical power. Ongoing and future work aimed at understanding the biology of childhood adversity and its effects will help to provide targets for intervention and prevention, as well as identify paths for how science, health care, and policy can combine efforts to protect and promote the psychological and physiological wellbeing of future generations.
