Do multigenerational homes moderate the intergenerational transmission of maternal adverse childhood experiences?

ABSTRACTBackground: Maternal adverse childhood experiences (ACEs) may lead to increased behavioural problems in children. However, the mediating roles of psychological distress and corporal punishment, two common mechanisms underlying the intergenerational transmission of maternal ACEs, in these relations have not been examined in Chinese samples. Multigenerational homes (MGH) are the dominate living arrangement in China; however, limited research focuses on the effects of MGHs on the intergenerational transmission of maternal ACEs.Objective: This study explored the parallel mediating effects of corporal punishment and psychological distress on the association between maternal ACEs and children's behaviour and whether MGHs can strengthen or weaken the relationship between maternal ACEs and corporal punishment or psychological distress.Participants and setting: Participants were 643 three-year-old children and their mothers (mean age of 32.85 years, SD = 3.79) from Wuhu, China.Methods: Mothers completed online questionnaires measuring ACEs, psychological distress, corporal punishment, their family structure, and children's behavioural problems. This study used a moderated mediation model.Results: The findings suggest that psychological distress and corporal punishment mediate the association between maternal ACEs and children's behavioural problems. The mediating role of corporal punishment was found depend on whether mothers and their children reside in MGHs. MGHs were not found to have a moderating role in the indirect relationship between maternal ACEs and children's behaviour problems via psychological distress.Conclusion: Our findings highlight the importance of addressing psychological distress and corporal punishment when designing interventions targeted Chinese mothers exposed to ACEs and their children, especially those living in MGHs.

Psychological distress and corporal punishment have parallel mediating roles in the associations between maternal adverse childhood experiences and offspring behavioural problems.Mothers with more adverse childhood experiences and in multigenerational homes were more likely to use corporal punishment.Multigenerational homes did not moderate the indirect relationship via psychological distress.

Conceptualizing Callous-Unemotional Traits in Chinese Preschoolers: Factor Structure and Measurement Invariance.

With the increasing use of the Inventory of Callous Unemotional Traits (ICU) to examine callous-unemotional traits, few studies have explicitly tested the most appropriate ICU factor structures and measurement invariance in Chinese children at preschool age. This study was conducted with a large community sample of 2055 Chinese preschoolers (53.6% male, M age = 62.23 months, SD = 9.91) to test the most appropriate model of ICU and the measurement invariance across parent gender, child gender, as well as age. The confirmatory factor model suggested that the two-factor model with 11 items (ICU-11) is the best-fitting model for a Chinese preschool sample, which includes a callousness and an unemotional factor. The results from measurement invariance revealed that the factor structures were invariant across child gender, as well as child age and parental gender. The finding suggested that the ICU-11 may be a useful tool for evaluating CU traits in Chinese preschoolers.

The Mediating Role of Callous-Unemotional Traits in the Relationship between Parental Aggression and Behavioral Problems among Chinese Preschoolers.

It is well known that aggressive parenting is associated with behavioral problems among Western children in their early childhood, but this has rarely been examined among Chinese preschoolers. The purpose of this study is to explore the relationship between aggressive parenting, callous-unemotional traits (CU traits), and behavioral problems among a large Chinese preschool sample. Data were collected in Wuhu city, China, from 1879 preschoolers (54% of whom were male) with a mean age of 65.66 months (standard deviation = 9.41). Parents provided information about the frequency of aggressive parenting, children's behaviors, and demographic characteristics via an online questionnaire. Mediation models were applied to analyze the associations between aggressive parenting, CU traits, and behavioral problems. Preschoolers' age, gender, and family socioeconomic status were considered as covariates. The findings of our study revealed that higher frequencies of parental psychological and physical aggression were associated with high levels of CU traits, which were related to increased levels of preschoolers' behavioral problems. This study extends previous studies by revealing a positive relationship between aggressive parenting and behavioral problems among Chinese preschoolers via CU traits and highlights the risks of aggressive parenting. Interventions for improving parenting strategies and lessening callous-unemotional traits should be developed to help reduce behavioral problems.

Maternal adverse childhood experiences and behavioral problems in Chinese preschool children: The moderated mediating role of emotional dysregulation and self-compassion.

BACKGROUND: The negative effects of maternal adverse childhood experiences (ACEs) may have a direct intergenerational effect on a child's behavior. This topic has been widely examined, but few studies have explored the underlying mechanism and protective factors influencing maternal ACEs and offspring's behavioral problems in the Chinese context. OBJECTIVE: This study aims to investigate the mediating effect of emotional dysregulation on the relationship between maternal ACEs and offspring behavior and examine whether self-compassion can moderate this association. PARTICIPANTS AND SETTING: The participants were 2282 preschoolers (52 % male) with a mean age of M = 62.63 months (SD = 9.28) and their mothers. They were from northern, central, and southern Anhui Province China, and data were collected in relation to the family's socioeconomic status by population density of children in the region. METHODS: Data were collected from the mothers with respect to maternal ACEs, emotional dysregulation, and self-compassion. Mothers provided information regarding children's behavior and demographic characteristics. A moderated mediation model was analyzed through SPSS. RESULTS: First, the presence of maternal ACEs was positively associated with offspring behavioral problems. Second, maternal emotional dysregulation mediated the relationship between ACEs and offspring behavioral problems. Third, mothers' self-compassion moderated the indirect relationship between ACEs and offspring behavioral problems via emotional dysregulation. CONCLUSIONS: Our findings highlight the critical role of emotional dysregulation and self-compassion in the relationship between maternal ACEs and offspring behavioral problems. Interventions should target maternal emotional dysregulation and self-compassion to minimize the risk of intergeneration transmission of negative effects.

Intergenerational associations of adverse and positive maternal childhood experiences with young children's psychosocial well-being.

Background: Maternal adverse childhood experiences (ACEs) are believed to have negative consequences on offspring health. However, positive childhood experiences (PCEs) may be concurrent with ACEs, and little is known about how ACEs and PCEs transmit intergenerationally in the context of each other.Objective: To explore the independent effect of maternal ACEs and PCEs on offspring psychosocial well-being and how ACEs and PCEs are intergenerationally transmitted in their context.Method: Data were 2587 mother-child dyads in Anhui provinces of China. Mothers retrospectively reported their ACEs and PCEs, as well as provided demographic characteristics and their children's psychosocial well-being. Logistic regression models were performed to explore the associations of maternal ACEs and PCEs with offspring psychosocial well-being.Results: Separate unadjusted logistic regression models showed that children with mothers reported high ACEs scores were more likely to have psychosocial challenges (total difficulties and prosocial problems), while children whose mothers reported high PCEs scores were less likely to have psychosocial challenges. When we added maternal ACEs and PCEs to a same model, we found that PCEs slightly neutralised the negative effects of ACEs on offspring's total difficulties and prosocial problems. When stratified by sample, mothers with high PCE scores and higher maternal ACEs were related with a higher risk of offspring total difficulties; mothers with low levels of ACEs and high PCEs tend to report a lower risk of offspring total difficulties.Conclusions: Results suggest that PCEs are positively and intergenerationally transmitted. Results suggest that PCEs are positively and intergenerationally transmitted. More programme should be provided to increase maternal PCEs. When preventing the intergenerational transmission of ACEs, specific interventions should be provided to mothers with different levels of PCEs.

Positive childhood experiences positively transmit intergenerationally.Stronger relationship between maternal ACEs and risk of offspring total difficulties was observed among mothers with above-average positive childhood experiences scores.A stronger relationship between maternal PCEs and fewer offspring total difficulties was observed among mothers with low adverse maternal childhood experiences scores.

Adverse Childhood Experiences, Resilience, and Emotional Problems in Young Chinese Children.

Resilience plays an important role in the relationship between adverse childhood experiences (ACEs) and children's health. Young children are often neglected in ACEs research and suffer from the negative consequences of ACEs. However, few studies have focused on the relationship between ACEs and emotional problems in young Chinese children and the moderating and mediating effect of resilience on this relationship. This study included young children at the beginning of their kindergarten year (n = 874, 42.80 ± 4.09 months) from Wuhu City, China, to examine the mediation and moderation effects of resilience on early-life ACEs and emotional problems. Our results show a positive direct effect of ACEs on emotional problems. Furthermore, a positive indirect effect of ACEs and emotional problems on resilience was found. A moderating effect of resilience was not observed in this study. Our findings (a) highlight the significance of paying more attention to early ACEs and revealing a better understanding of the effect of resilience on ACEs at an early age and (b) indicate that age-specific interventions should be provided to enhance young children's resilience when exposed to adversity.

Patterns of adverse childhood experiences among Chinese preschool parents and the intergenerational transmission of risk to offspring behavioural problems: moderating by coparenting quality.

Background: Although intergenerational transmission of ACEs among parents and their offspring have been extensively studied in the West, few studies have been conducted in China on preschool children and their parents, and explore the protective fact for the intergeneration transmission. Objective: Using latent class analysis and moderation model, this study examined the associations between patterns of adverse childhood experiences of Chinese preschool parents and behavioural problems in their children and whether coparenting quality plays a protective role in this relationship. Method: A retrospective study was conducted on 3091 parent-child dyads from 11 kindergartens in the northern, central, and southern Anhui provinces in China. Online questionnaires were used to collect the data. Parents reported adverse childhood experiences (ACEs) and provided information on their children's behavioural problems and perceived coparenting quality. Latent class analysis and a moderating model were used to examine the associations between patterns of adverse childhood experiences of Chinese preschool parents and behavioural problems in their children, and the moderating role of coparenting quality. Results: Four classes were identified: a high ACEs group, a violent victimisation group, a child abuse and physical neglect group, and a low ACEs group. Increasing levels of co-parenting quality were associated with reduced parent-reported child behaviour problems for all classes, and that potentially buffering effect was significantly stronger for the low ACEs class than for children whose parents in high ACEs class. Conclusions: Exposure to high ACEs increases the risk of developing behavioural problems in offspring, and coparenting quality may serve as a protective mechanism for intergenerational transmission. Future research should develop and implement interventions to support disadvantaged, at-risk parents and promote coparenting quality.

Antecedentes: Aunque la transmisión intergeneracional de ACEs entre padres y su descendencia ha sido extensivamente estudiada en el Occidente, pocos estudios han sido conducidos en niños preescolares de China y sus padres, así como del factor protector para la transmisión intergeneracional.Objetivo: Mediante el análisis de clase latente y un modelo de moderación, este estudio examinó las asociaciones entre patrones de experiencias adversas en la infancia de padres de preescolares en China y problemas conductuales en sus hijos, y si la calidad de la crianza compartida juega un rol protector en esta relación.Método: Un estudio retrospectivo se condujo en 3091 díadas padre-hijo de 11 establecimientos preescolares en provincias del norte, central y sur de Anhui en China. Se usaron cuestionarios en línea para recolectar los datos. Los padres reportaron experiencias adversas en su infancia (ACEs por sus siglas en inglés) y aportaron información sobre los problemas conductuales de sus hijos y la calidad de la crianza compartida percibida. Se utilizaron análisis de clase latente y un modelo moderador para examinar las asociaciones entre los patrones de experiencias adversas en la infancia de padres de preescolares chinos y problemas conductuales en sus hijos, y el rol moderador de la calidad de la crianza compartida.Resultados: Se identificaron cuatro clases: un grupo ACEs elevado, un grupo de victimización violenta, un grupo de abuso infantil y negligencia física y un grupo de ACEs bajo. Los niveles crecientes de calidad de crianza compartida se asociaron con una reducción de problemas conductuales de los niños reportados por los padres en todas las clases, y ese efecto amortiguador potencial fue significativamente más fuerte para la clase ACEs baja que para los niños cuyos padres estaban en la clase ACEs elevada.Conclusiones: La exposición a ACEs elevados aumenta el riesgo de desarrollar problemas conductuales en la descendencia, y la calidad de la crianza compartida puede servir como un mecanismo protector para la transmisión intergeneracional. Investigaciones futuras deberían desarrollar e implementar intervenciones para apoyar a padres en desventaja y de alto riesgo y promover la calidad de la crianza compartida.

Observation of exceptional point in a PT broken non-Hermitian system simulated using a quantum circuit.

Exceptional points (EPs), the degeneracy points of non-Hermitian systems, have recently attracted great attention because of their potential of enhancing the sensitivity of quantum sensors. Unlike the usual degeneracies in Hermitian systems, at EPs, both the eigenenergies and eigenvectors coalesce. Although EPs have been widely explored, the range of EPs studied is largely limited by the underlying systems, for instance, higher-order EPs are hard to achieve. Here we propose an extendable method to simulate non-Hermitian systems and study EPs with quantum circuits. The system is inherently parity-time (PT) broken due to the non-symmetric controlling effects of the circuit. Inspired by the quantum Zeno effect, the circuit structure guarantees the success rate of the post-selection. A sample circuit is implemented in a quantum programming framework, and the phase transition at EP is demonstrated. Considering the scalable and flexible nature of quantum circuits, our model is capable of simulating large-scale systems with higher-order EPs.

Hyperfine spectroscopy in a quantum-limited spectrometer.

We report measurements of electron-spin-echo envelope modulation (ESEEM) performed at millikelvin temperatures in a custom-built high-sensitivity spectrometer based on superconducting micro-resonators. The high quality factor and small mode volume (down to 0.2 pL) of the resonator allow us to probe a small number of spins, down to 5×102. We measure two-pulse ESEEM on two systems: erbium ions coupled to 183W nuclei in a natural-abundance CaWO4 crystal and bismuth donors coupled to residual 29Si nuclei in a silicon substrate that was isotopically enriched in the 28Si isotope. We also measure three- and five-pulse ESEEM for the bismuth donors in silicon. Quantitative agreement is obtained for both the hyperfine coupling strength of proximal nuclei and the nuclear-spin concentration.
