Grandmother-grandchild physiological synchrony in Chinese three-generation families: Links with child emotion regulation.

The current study examined the characteristics of physiological synchrony between grandmothers and grandchildren in Chinese three-generation families, and the associations between physiological synchrony and child emotion regulation. The participants included 92 children (age 8-10-year old) and their grandmothers. Respiratory sinus arrhythmia (RSA) was collected from both grandmothers and their grandchildren throughout a collaborative drawing task and a conflict discussion task. Child emotion regulation was measured using the Children's Emotional Management Scale. We found no evidence for an overall pattern of concordant or discordant synchrony within dyads. Instead, there was great variability in patterns of synchrony across dyads. During the collaborative drawing task, concordance in grandmother's RSA and grandchildren's subsequent RSA was linked with better emotion regulation. During the conflict discussion, concordance in grandmother's RSA and grandchildren's simultaneous RSA was linked with poorer emotion regulation. These results suggest that grandmother-grandchild synchrony in different directions, time lags, and contexts has different influences on children's emotion regulation. The findings of this study highlight the importance of contextual physiological co-regulation between Chinese children and their grandmothers for children's social-emotional development.

Parental psychological control and children's self-esteem: A longitudinal investigation in children with and without oppositional defiant problems.

Oppositional defiant problems are among the most prevalent psychological problems among children and adolescents from China and across the world. Still little is understood about how self-esteem, in conjunction with parenting experiences, develops in children with oppositional defiant problems. We addressed this gap of knowledge in a two-year longitudinal study. Specifically, we explored how parental psychological control predicts children's self-esteem levels over time, and in turn, how children's self-esteem levels predict parental psychological control. We collected data in Chinese children (ages 8 to 13 at T1) with (N = 224) and without (N = 217) oppositional defiant problems, and tested three-wave cross-lagged panel models. Multigroup analyses showed that the associations between parental psychological control and children's self-esteem were the same for children with and without oppositional defiant problems. Results for the total sample revealed bi-directional associations between maternal psychological control and children's self-esteem. Children who perceived more psychological control from their mothers were likely to exhibit lower self-esteem over time, and vice versa, children with lower self-esteem were likely to perceive more maternal psychological control over time. Conversely, a unidirectional paternal effect was observed in father-child dyads. Our findings help understand the parent-child dynamics that shape the psychological development of children with oppositional defiant problems.

A virtuous cycle between meaning in daily life and state mindfulness as well as the unique role of depression among young adults: A diary study.

The positive association between meaning in life (MIL) and mindfulness has been supported; however, previous research has been limited to the trait level. To explore the dynamics of mindfulness and MIL in the state level, the present study used the experience sampling method (ESM) and conducted a dynamic structural equation model (DSEM). In addition, we examined the moderation of baseline depression in this dynamic relationship and the protective role of the dynamics on depression. We recruited 184 college students (Mage = 21.58, 33.15% male), who reported three times a day for 14 consecutive days, and analyzed the 7726 collected responses. Firstly, a virtuous cycle between mindfulness and MIL was proven. Besides, the baseline depressive symptoms moderated the predictive of mindfulness on MIL, suggesting state mindfulness gave people with more depressive symptoms more meaningful in daily life. Lastly, the result also demonstrated the positive prediction of mindfulness on MIL and alleviated the worsening of depressive symptoms within 2 weeks. The findings extended the relationship between MIL and mindfulness from trait level to state level, enriching the self-determination theory, and examined the unique effect of depressive symptoms in the dynamics.

Transmission of depressive symptoms in the nuclear family: a cross-sectional and cross-lagged network perspective.

Children are more likely to develop depressive symptoms in families where parents have depressive symptoms. By conceptualizing the individual depressive symptom network of each family member as a whole, this study proposes a family symptom network model, and explored the mechanisms of transmission of depression within nuclear families at the symptom level. This study used four waves (2012, 2016, 2018, 2020) of data from the China Family Panel Studies (CFPS), which in wave one contained a representative sample of 1963 children (1038 boys; age = 12.60), 4763 mothers and 4614 fathers from China. Children with their parents completed the Center for Epidemiology Studies Depression Scale at each wave. Individual depressive symptom networks among children, fathers, and mothers were highly similar and stable across time. When considering depressive symptoms of all family members as a whole, there was a wide range of associations between child, father, and mother depressive symptom networks. The results of the cross-lagged network model suggest the bidirectional relationships between couples and parent-child depression. The current study provides preliminary validation of the family symptom network model. The model represents a further integration and extension of network theory of mental disorders and family systems theory, and points out the limitations of studying the intergenerational transmission of depression from a latent variable perspective. Thus, the family symptom network model proposed in this study could provide valuable new insights into understanding the intergenerational transmission of depression.

Comparing positive reappraisal and mindfulness in relation to daily emotions during COVID-19: An experience sampling study.

Research has suggested that daily cognitive reappraisal and mindfulness are differentially associated with emotional experience. Nevertheless, the different relationship between these two emotion regulation strategies and emotional experience remains unexplored amidst the COVID-19 pandemic, when people were facing unprecedented challenges and disruptions in their everyday lives. The current study aimed to examine the potential unidirectional or bidirectional relations between two strategies and daily emotional experience during the COVID-19 pandemic and whether the associations between the two strategies and emotional experience varied. A total of 184 college students participated in this study. Daily positive reappraisal, mindful attention and awareness (MAA), positive and negative affect, and COVID-19-related stress were assessed utilizing experience sampling method (three times a day for 14 consecutive days). Results suggested that the directionality of the link between the two strategies and daily emotional experience differed. The links between positive reappraisal and positive affect, negative affect, and COVID-19-related stress were transactional. However, a unidirectional relation was observed between positive affect and subsequent MAA. The study provided support for the contextual perspective of emotion regulation by demonstrating that the efficacy of regulation strategies is contingent upon the context. The identification of optimal conditions for effective strategies remains a crucial area for future research.

Longitudinal relationship between oppositional defiant disorder symptoms and attention-deficit/hyperactivity disorder symptoms in Chinese children: insights from cross-lagged panel network analyses.

Oppositional defiant disorder (ODD) and attention-deficit/hyperactivity disorder (ADHD) are two of the most common childhood mental disorders, and they have substantial comorbidity. The developmental precursor model has long been widely used to explain the mechanisms of comorbidity between ODD and ADHD, however whether it is equally effective at the symptomatic level is unclear. Therefore, this study aimed to (a) examine the stability of the ODD and ADHD comorbidity network in a longitudinal sample of high-risk children in China; and (b) examine the longitudinal relationship between the ODD and ADHD symptom networks based on a developmental precursor model. Two hundred sixty-three Chinese children aged 6 to 13 years with ODD and/or ADHD were assessed for symptoms of ODD and ADHD in two surveys conducted 1 year apart. We used data from these two time points to construct two cross-sectional networks and a cross-lagged panel network (CLPN) to explore the symptom network for comorbidity of ODD and ADHD. The analysis shows that: (1) the two cross-sectional networks are highly similar in terms of structure, existence of edges, centrality estimates, and the invariance test shows that there is no significant difference between them. The symptoms "follow through", "interrupts/intrudes", "difficulty playing quietly" and "concentration" had the highest expected influence centrality at both time points. (2) Combined with the results of the cross-sectional and cross-lagged networks, we found that "annoy" and "blame" are potential bridge symptoms between the ODD and ADHD symptom networks. The symptom "annoy" forms a reciprocal predictive relationship with "interrupts/intrudes", while "blame" unidirectionally predicts "close attention". In addition, we found that "vindictive" predicted numerous ADHD symptoms, whereas "angry" was predicted by numerous ADHD symptoms. The findings emphasize the broad predictive relationship between ODD and ADHD symptoms with each other, and that ODD symptoms may lead to activation of the ADHD symptom network and vice versa. These findings suggest that the developmental precursor model at the symptom level may partially explain the comorbidity mechanisms of ODD and ADHD, and future studies should further investigate the underlying multiple mechanisms.

Longitudinal relationship between child maltreatment, bullying victimization, depression, and nonsuicidal self-injury among left-behind children in China: 2-year follow-up.

BACKGROUND: Left-behind childre (LBC) in China are deeply concerned by society because of their high risk of emotional and behavioral problems. Depression and nonsuicidal self-injury are the most harmful and worrying negative emotional and behavioral problems in LBC. Unfortunately, LBCs are in unfavorable environments for a long time and are prone to negative interpersonal interactions. Child maltreatment and bullying victimization, as the two most typical negative interpersonal interactions in family and school environments, maybe the key risk factors for depression and nonsuicidal self-injury among LBCs. However, we are less known of the longitudinal effects of child maltreatment and bullying victimization on LBC's depression and nonsuicidal self-injury and their underlying mechanisms. AIMS: This study used a two-year longitudinal design with three-time points to investigate the longitudinal effects of child maltreatment and bullying victimization on depression, nonsuicidal self-injury, and the mediating role of negative thoughts and self-compassion. MATERIALS & METHODS: A sample of 592 LBC (390 were males, Mage at time 1 = 9.56, SDage = 0.65; 202 were females, Mage at time 1 = 9.43, SDage = 0.63) completed a set of questionnaires at three-time points. This study used SPSS software (version 25.0) and MPLUS software (version 8.3) for all analyses. RESULTS: (1) Child maltreatment not only affects depression and nonsuicidal self-injury but also affects depression and nonsuicidal self-injury through negative thoughts. Child maltreatment affects depression through self-compassion and does not affect nonsuicidal self-injury. (2) Bullying victimization affects depression and nonsuicidal self-injury through negative thoughts and bullying victimization further affects depression through self-compassion but does not affect nonsuicidal self-injury. CONCLUSION: This study revealed the effects of negative interpersonal interactions (child maltreatment, bullying victimization) on LBC's adverse emotions and behaviors, and their underlying mechanisms, which helps to provide parents, schools, and psychoeducational workers with a new perspective on intervention.

Development of the Panic Response Scale and the Predicting Factors of Panic Response During the COVID-19 Pandemic.

Introduction: During emergencies, individuals and communities often react in a variety of ways, including panic response. However, the study of panic response is limited due to narrow assessment tools that measure only one or two dimensions of human response (eg, physiology, cognition, emotion, and behavior). To address this limitation and to explore the risk and protective factors of panic response during the global spread of the Coronavirus Disease 2019 (COVID-19), the current study developed and evaluated the Panic Response Scale (PRS). Methods: Four samples were recruited for the following purposes: interview analysis (n = 26); item analysis and exploratory factor analysis (n = 604); confirmatory factor analysis and reliability analysis (n = 603); and retest reliability, validity analysis, and regression analysis (n = 349). Results: The PRS consists of 21 items with four subscales: Physical Discomfort, Anxious Fluster, Sensitive Depression, and Excessive Prevention. Each of these subscales demonstrated good internal consistency (rs > 0.73), test-retest reliability (rs > 0.77), criterion validity (r = 0.69, p < 0.01), and convergent validity (rs = 0.31-0.65, p < 0.01). Regression analysis revealed significant predicting effects of COVID-19 knowledge and neuroticism on panic response. Additionally, cognitive reappraisal moderated the association between neuroticism and panic response. Discussion: Following a traumatic event, the PRS offers a potential tool for identifying individuals in need of mental health services. Moreover, during the COVID-19 pandemic, knowledge and neuroticism served as risk factors for heightened panic response, while cognitive reappraisal served as a protective factor for coping with panic response.

Oppositional Defiant Disorder Symptoms and Multi-level Family Factors in Chinese Migrant Children: A Network Perspective.

Based on the network theory of mental disorders, this study used network analysis to examine the network of ODD symptoms and multilevel family factors and identify the most crucial family factors influencing ODD symptoms in children. A total of 718 Chinese migrant children aged 7-14 years participated in this study. This study measured ODD symptoms, family system-level variables (3 factors), family dyadic-level variables (6 factors), and family individual-level variables (6 factors) with factors selected based on the multilevel family factors theory of ODD symptoms. The results indicated that (1) "annoy" was the center symptom of ODD, (2) "annoy" and "vindictive" was the main bridge connecting the multilevel family factors, and (3) family cohesion at the family system level, parent-child conflict at the family dyadic level, and parental depression at the family individual level were critical central and bridging influencing factors. The findings of this study highlight the critical role of "annoy" and "vindictive" symptoms in the activation of ODD symptom networks in children and provide a basis for future improvements in diagnostic criteria. These potential core and bridge factors might become key intervention targets for childhood ODD.

Patterns of Chromosomal Variation, Homoeologous Exchange, and Their Relationship with Genomic Features in Early Generations of a Synthetic Rice Segmental Allotetraploid.

Polyploidization is a driving force in plant evolution. Chromosomal variation often occurs at early generations following polyploid formation due to meiotic pairing irregularity that may compromise segregation fidelity and cause homoeologous exchange (HE). The trends of chromosomal variation and especially factors affecting HE remain to be fully deciphered. Here, by whole-genome resequencing, we performed nuanced analyses of patterns of chromosomal number variation and explored genomic features that affect HE in two early generations of a synthetic rice segmental allotetraploid. We found a wide occurrence of whole-chromosome aneuploidy and, to a lesser extent, also large segment gains/losses in both generations (S2 and S4) of the tetraploids. However, while the number of chromosome gains was similar between S2 and S4, that of losses in S4 was lower than in S2. HEs were abundant across all chromosomes in both generations and showed variable correlations with different genomic features at chromosomal and/or local scales. Contents of genes and transposable elements (TEs) were positively and negatively correlated with HE frequencies, respectively. By dissecting TEs into different classes, retrotransposons were found to be negatively correlated with HE frequency to a stronger extent than DNA transposons, whereas miniature terminal inverted elements (MITEs) showed a strong positive correlation. Local HE frequencies in the tetraploids and homologous recombination (HR) rates in diploids within 1 Mb sliding windows were significantly correlated with each other and showed similar overall distribution profiles. Nonetheless, non-concordant trends between HE and HR rates were found at distal regions in some chromosomes. At local scale, both shared and polymorphic retrotransposons between parents were negatively correlated with HE frequency; in contrast, both shared and polymorphic MITEs showed positive correlations with HE frequency. Our results shed new light on the patterns of chromosomal number variation and reveal genomic features influencing HE frequency in early generations following plant polyploidization.

Unidirectional or Bidirectional? Relation between Parental Responsiveness and Emotion Regulation in Children with and without Oppositional Defiant Disorder.

Parenting is crucial for emotion regulation in children. Much less is known, however, concerning the association between parenting and emotion regulation in children with oppositional defiant disorder (ODD), who are known to have poor emotion regulation. The current study aimed to examine how parental responsiveness and child emotion regulation related either unidirectionally or bidirectionally to one another over time and to investigate whether the associations were different in ODD and non-ODD groups. Data were collected each year for three consecutive years from a sample of 256 parents of children with ODD and 265 parents of children without ODD in China. The results from the random intercepts cross-lagged panel model (RI-CLPM) suggested that the directionality of the link between parental responsiveness and child emotion regulation differs according to ODD status. The non-ODD group demonstrated a unidirectional link between early emotion regulation and subsequent parental responsiveness, consistent with the "child effect". However, in the ODD group, the link between parental responsiveness and emotion regulation was transactional, in line with social coercion theory. Multiple-group comparisons found that increased parental responsiveness was more strongly associated with improved child emotion regulation in the ODD group only. The research established a dynamic and longitudinal relationship between parental responsiveness and emotion regulation and suggested that intensive interventions should aim to improve parental responsiveness to children with ODD.

Vicious cycle of emotion regulation and ODD symptoms among Chinese school-age children with ODD: a random intercept cross-lagged panel model.

A strong link between children's emotion regulation and oppositional defiant disorder (ODD) symptoms has been documented; however, the within-person mechanisms remain unclear. Based on the self-control theory and self-regulation theory, our study investigated the longitudinal, bidirectional relationship between emotion regulation and ODD symptoms in school-age children with ODD using parent- and teacher-reported data, respectively. A total of 256 Chinese elementary school students participated in a three-wave longitudinal study spanning two years. We used the random intercept cross-lagged panel model (RI-CLPM) to investigate the concurrent and longitudinal associations between emotion regulation and ODD symptoms. Results from the RI-CLPMs revealed that ODD symptoms were negatively correlated with emotion regulation and positively correlated with emotion lability/negativity at both the between-person and within-person levels across settings. Additionally, in the school setting, emotion regulation negatively predicted subsequent ODD symptoms but not vice versa, whereas emotion lability/negativity was bidirectionally associated with ODD symptoms over time. The longitudinal associations of ODD symptoms with emotion regulation and lability/negativity were not observed in the home setting. These findings suggest a circular mechanism between children's emotion regulation and ODD symptoms and support the view that emotion regulation, particularly emotion lability/negativity, plays an important role in the development of ODD symptoms.

Intergenerational effects of childhood maltreatment: The relationships among parental childhood emotional neglect, emotional expressiveness and children's problem behaviors.

BACKGROUND: Childhood maltreatment has a severe impact on both the health and parenting styles of abused individuals in adulthood, and it even has a negative impact on the offspring of abused individuals. Although studies have confirmed the intergenerational effects of childhood maltreatment, relatively few have emphasized emotional neglect and its mechanism of intergenerational effects. Additionally, few studies have examined the unique role of fathers and how mothers and fathers interact with one another. OBJECTIVE: The current study aimed to employ the actor-partner interdependence mediation model to investigate the relationship between parental childhood emotional neglect and children's problem behaviors, as well as whether parents' positive and negative emotional expressiveness plays a mediating role. METHODS, PARTICIPANTS, AND SETTING: In total, 397 dyads of mothers and fathers of children aged 6-9 were recruited and reported their childhood emotional neglect experience and emotional expressiveness, and mothers also rated their children's problem behaviors. RESULTS: The findings revealed that (a) maternal childhood emotional neglect was associated solely with mothers' own negative emotional expressiveness, followed by their children's problem behavior and (b) paternal childhood emotional neglect showed no effect on children's problem behavior through fathers' own or their spouses' positive and negative emotional expressiveness. CONCLUSIONS: The findings of this study suggest that childhood emotional neglect has intergenerational effects and that mothers' parenting behaviors are relatively important in preventing adverse effects on their children.

Potential Effects of Metal Oxides on Agricultural Production of Rice: A Mini Review.

The extensive usage of metal oxide nanoparticles has aided in the spread and accumulation of these nanoparticles in the environment, potentially endangering both human health and the agroecological system. This research describes in detail the hazardous and advantageous impacts of common metal oxide nanomaterials, such as iron oxide, copper oxide, and zinc oxide, on the life cycle of rice. In-depth analyses are conducted on the transport patterns of nanoparticles in rice, the plant's reaction to stress, the reduction of heavy metal stress, and the improvement of rice quality by metal oxide nanoparticles, all of which are of significant interest in this subject. It is emphasized that from the perspective of advancing the field of nanoagriculture, the next stage of research should focus more on the molecular mechanisms of the effects of metal oxide nanoparticles on rice and the effects of combined use with other biological media. The limitations of the lack of existing studies on the effects of metal oxide nanomaterials on the entire life cycle of rice have been clearly pointed out.

Contributions of Multilevel Family Factors to Emotional and Behavioral Problems among Children with Oppositional Defiant Disorder in China.

Oppositional defiant disorder (ODD) is one of the most prevalent childhood mental health disorders and is extremely affected by family factors. However, limited studies have addressed the issue from the perspective of family systems. The current study examines the associations between multilevel family factors (i.e., family cohesion/ adaptability at system level, mother-child and father-child attachment at a dyadic level, and child self-esteem at an individual level) and emotional and behavioral problems among children with ODD in China. The participants were 256 Chinese children with ODD and their parents and class master teachers. A multiple-informant approach and structural equation model were used. The results revealed that system level factors (family cohesion/adaptability) were associated with child emotional and behavior problems indirectly through factors at the dyadic level (mother-child attachment) and the individual level (child self-esteem) in sequence. Mother-child, but not father-child, attachment, mediated the linkage between family cohesion/adaptability and the emotional problems of children with ODD. Moreover, child self-esteem mediated the association between mother-child attachment and child emotional and behavioral problems. The findings of the present study underscored that multilevel family factors are uniquely related to emotional and behavioral problems in children with ODD.

The Double-Edged Impact of the COVID-19 Pandemic on Chinese Family Relationships.

To comprehensively understand the Chinese family relationships (i.e., marital relationship, parent-child relationship, sibling relationship, and grandparent-grandchild relationship) during the COVID-19 pandemic, this study investigated the changes of family relationships and the individual differences related to knowledge of the COVID-19, personality traits (i.e., neuroticism and optimism), and emotional characteristics (i.e., emotion regulation and negative emotional reactions). From March 1 to April 5, 2020, 8821 participants were involved, including 3995 teenagers, 1146 unmarried young adults, 3571 married adults, and 109 grandparents. Results revealed a double-edged pattern that people experienced both positive changes and negative changes during the pandemic. Teenagers reported significant negative changes in the relationships with their parents. Peoples' knowledge of the COVID-19, neuroticism, optimism, emotion regulation, and negative emotional reactions were in varying extents to which accounted for the individual differences in the changes of family relationships. These findings help recognize the overall Chinese family relationships during the hard period.

Caregivers' joint depressive symptoms and preschoolers' daily routines in Chinese three-generation families: Does household chaos matter?

The benefits of routines for children have been consistently demonstrated in previous literature. However, factors that may confer risks for child routines have seldom been examined, particularly in families where parents and grandparents co-care the children. This study aimed to investigate the associations of parents' and grandparents' depressive symptoms with preschoolers' daily routines in Chinese three-generation families and to determine whether household chaos mediated or moderated the associations. The participants were from 171 urban three-generation families where mothers, fathers, and grandmothers (97 paternal and 74 maternal) were primary caregivers. Mothers, fathers, and grandmothers reported their depressive symptoms at Wave 1; at Wave 2 (during the COVID-19 pandemic), caregivers reported household chaos and child routines. The results revealed that child routines were negatively predicted by parents' joint depressive symptoms rather than grandmothers' depressive symptoms. In the associations, household chaos acted as a mediator rather than a moderator. Specifically, household chaos marginally mediated the associations between parents' and grandmothers' depressive symptoms and child routines only in maternal three-generation families. These findings suggest that in three-generation families, caregivers with more depressive symptoms may elicit more chaotic family environments, which may in turn compromise their children's daily routines.

Latent profiles of adolescents' relationships with parents and siblings: Associations with emotional and behavioral responses during the COVID-19 pandemic.

The purpose of this study is to identify the latent profiles of Chinese adolescents' family (parent-adolescent and sibling) relationships prior to and during the COVID-19 pandemic, as well as associations between those profiles and adolescents' emotional and behavioral responses. A total of 2,305 adolescents from China aged between 10 and 18 years completed measures of parent-adolescent relationships, sibling relationships, and emotional and behavioral responses during the pandemic. Four profiles of family relationships were identified via latent profile analysis and categorized as Cohesive-Decline, Mild-Decline, Conflictual-Stable, and Indifferent-Stable. Adolescents with a Conflictual-Stable profile reported more emotional and behavioral responses compared to the other profiles. In contrast, adolescents with a Cohesive-Decline profile exhibited fewer emotional responses compared to the other profiles. Adolescents with a Mild-Decline profile had fewer emotional responses than those with an Indifferent-Stable profile. These results shed light on the patterns and consequences of family relationships during the COVID-19 pandemic and have substantial implications for interventions involving family relationships in the context of regular epidemic prevention and control.

A Systematic Review of Multiple Family Factors Associated with Oppositional Defiant Disorder.

Oppositional Defiant Disorder (ODD) is characterized by a recurrent pattern of angry/irritable emotional lability, argumentative/defiant behavior, and vindictiveness. Previous studies indicated that ODD typically might originate within a maladaptive family environment, or was at least maintained within such an environment. As such, the present review summarized pertinent research from the last 20 years that focused on the pathways connecting family risk factors to the development of child ODD symptoms. A systematic search of electronic databases was completed in August 2020, resulting in the inclusion of 62 studies in the review. The review established a multi-level framework to describe the mechanisms underlying the pathway from familial factors to ODD psychopathological symptoms: (a) the system level that is affected by the family's socioeconomic status and family dysfunction; (b) the dyadic level that is affected by conflict within the marital dyad and parent-child interactions; and (c) the individual level that is affected by parent and child factors. Additionally, from the perspective of family systems theory, we pay special attention to the interactions among and between the various levels of the pathway (moderation and mediation) that might be associated with the occurrence and severity of ODD symptoms. Considering future prevention and intervention efforts, this three-level model emphasizes the necessity of focusing on familial risk factors at multiple levels and the mechanisms underlying the proposed pathways.

Longitudinal Relationship Between Bullying Victimization and Depression Among Left-Behind Children: Roles of Negative Thoughts and Self-Compassion.

Background: Left-behind children (LBC) in China have aroused widespread concern in society and the academic field because they have a high risk of psychological problems. For left-behind children, depression is the most serious problem. Bullying victimization has been evidenced as one of the most common causes of children's depression. However, less is known about its longitudinal association and the process for how bullying victimization influences depression among left-behind children. Thus, the presentation aims to explore the mechanisms underlying by considering the roles of left-behind children's negative thoughts and self-compassion. Methods: The 3-wave longitudinal data were collected from a sample of 605 aged 8-11 from central China. We used the Olweus bully and victimization questionnaire, the children's automatic thoughts scale, the depression scale, and the self-compassion scale. Results: Bullying victimization positively predicted the depression level of left-behind children. Negative thoughts and self-compassion mediate the relationship between bullying victimization and depression. In the mechanism of bullying victimization on depression exists gender differences among left-behind children. Conclusion: The present study suggested the association between bullying victimization and left-behind children's depression and revealed the internal mechanism of negative thoughts and self-compassion. These findings provide a new perspective for left-behind children's mental health education and intervention.
