Background:Parents of children with autism are susceptible to parenting burnout due to tremendous parenting burden and parenting challenges.Parenting burnout has a detrimental effect on both children with autism and their parents.However,the underlying mechanisms that lead to parenting burnout remain unclear.This study aimed to investigate the relationship between parenting stress and parenting burnout,along with the serial mediation effect of social support and coping strategies in the context of families with autistic children.Methods:We conducted a cross-sectional study in 231 parents of autistic children in four autism facilities located in central Hubei province.Data were collected through the Parental Stress Index,Social Support Rating Scale,Simplified Coping Strategies Questionnaire,and Caregiver Burnout Assessment Questionnaire.Results:Parenting stress and burnout status were:72.3%of parents reported high-stress levels,16.9%experienced risks for parenting burnout,and 19.9%were currently experiencing burnout.Both social support and coping strategies played partial mediating roles in the relationship between parental stress and burnout,forming a serial mediation effect.Conclusion:Parenting stress is a risk factor for parenting burnout.Social support and coping strategies play a chain mediating role between parenting stress and parenting burnout,which may act as the underlying mechanisms.The study offers insights into potential intervention points for reducing parenting burnout.Future efforts are needed to devote to parenting stress,social support and coping strategy to enhance the psychological well-being of parents with autistic children. 展开更多

Good mental well-being is necessary for achievement in science at any level.There are extrinsic factors that have the potential to determine a learner’s mental well-being,and the role of the parent(s)cannot be undermined.Therefore,this study examined the relationships between parental engagement(PE),parents’attitude to science(PAS),and mental well-being(MWb)among junior science students.This descriptive survey involved a population of Junior Secondary Three(3)students studying Basic Science in public co-educational schools.A sample of three hundred(300)respondents was randomly drawn from 10 schools within the metropolis.Quantitative data were sourced using three validated questionnaires and analyzed using descriptive and inferential statistics.The research showed that PE(2.19)and PAS(2.13)are relatively high,while MWb(2.51)is moderately normal.The influence of PE and PAS on MWb is significant.Both PE and PAS have a significant positive relationship with MWb.Also,PE and PAS were found to jointly contribute to students’MWb.In conclusion,PE and PAS have implications for the child’s mental well-being and ultimate success in science.We,therefore,recommend that more parental engagement be encouraged by improving sensitization,and orientation programs could be organized for parents of science students.This may provide an avenue for parents to be better equipped to support their young scientists. 展开更多

People that herd livestock for a living are known as herders,and they are found throughout Mongolia’s wild vast steppe.The purpose of the study is to investigate herder parents’belief systems for preparing the un-preschooled children for schooling in the context of herder community in rural Mongolia.The belief systems of herder parents are shaped by three main characteristics:They lack a clear plan for their children’s education,are deeply concerned about it,and feel incapable of preparing their children for formal schooling.Herders’lives revolve around their livestock,and they must remain flexible,moving when necessary due to factors like water scarcity and poor grazing conditions caused by insufficient rain.While they desire better education for their children,the nomadic lifestyle makes it difficult to achieve.Herder parents’attitudes are contradictory;they want their children to be educated and live in urban areas,yet they also prefer them to become herders rather than educated but unemployed individuals.The hard work of herding makes them reluctant to pass it on to the next generation. 展开更多

Background:Despite increasing attention to parental educational anxiety in China’s educational system,the underlying mechanisms through which this anxiety affects adolescent academic performance remain unclear.This study aims to investigate how parental educational anxiety influences academic outcomes through depression and self-efficacy while considering the role of problematic social media use in today’s digital age.Methods:Data analysis was conducted using stratified random cluster sampling techniques.Participants for this study were recruited from middle and high schools in China.The sample comprised 2579 traditional two-parent families,each consisting of a pair of parents and one child.The commencement of data collection occurred in March 2024.A range of analytical techniques was employed to examine the relationship between parental education anxiety and student academic performance,including bivariate correlations,path analysis,mediation analysis,and moderation analysis.Results:The study findings revealed that parental educational anxiety negatively predicted student academic performance(β=−0.510,t=−35.011,p<0.001).Furthermore,a significant and negative relationship was identified between student depression and self-efficacy(β=−0.179,t=−8.336,p<0.001),which was chain-mediated.Additionally,problematic social media use moderated the relationship between parental educational anxiety and student academic performance(p<0.001),with stronger negative effects at higher levels of social media use.Conclusion:This study demonstrates that parental educational anxiety has both direct and indirect negative associationswith student academic performance through complex psychological pathways.The findings reveal a sequential mediation mechanism where parental educational anxiety first influences student depression,which in turn affects self-efficacy,ultimately impacting academic performance.The strength of these relationships is notably moderated by problematic social media use,with higher levels of social media engagement amplifying the negative association between parental educational anxiety and academic outcomes.These findings illuminate the complex interplay between family dynamics,student mental health,and educational achievement in the contemporary digital age. 展开更多

Autism spectrum disorder is a developmental disorder impacting a child’s social interactions,behaviors,and communication skills.One of the crucial aspects of autism care,which is often overlooked,is the parent’s mental health status while trying to improve and overcome challenges faced by their child.A study by Lu et al examined the effectiveness of remote family psychological support courses on the mental health status of parents having children with autism spectrum disorder.It was found that the integration of these remote psychological courses with conventional care had a positive impact on the parents by reducing their stress levels,leading to an increase in their competence,and hence they could engage effectively in child therapy.However,a long-term study is necessary to assess whether these interventions have a sustained effect.The study emphasizes the need for developing such culturally sensitive intervention models on a global scale,making them accessible to all and improving autism care support. 展开更多

BACKGROUND Intellectual disability(ID),affecting 1%-3%of children globally,presents significant challenges for parents that often translate into occupational stress.While studies document elevated parenting stress levels(33.57 vs 26.46 in controls),job-related impacts remain poorly understood.This study employs propensity score matching(PSM)to rigorously analyze work stress determinants among parents of preschool-aged children with ID,controlling for socioeconomic and behavioral confounders.The research bridges a critical gap by examining how workplace demands intersect with special caregiving responsibilities,aiming to identify modifiable risk factors for targeted interventions.Findings will inform evidence-based workplace accommodations and support policies,offering novel insights into the occupational consequences of parenting a child with ID through advanced causal inference methods.This work holds important implications for hazard ratio(HR)policies and social support systems serving this vulnerable population.AIM To explore the factors affecting the job stress of parents of preschool children with mental retardation(MR),based on the PSM.METHODS One hundred and twenty-five children aged 3-6 years who were treated in our hospital from December 2022 to December 2024 were included in the questionnaire survey.Five cases were excluded due to incomplete data,and 120 cases completed the study.The questionnaire was filled out by the parents of the children,and 100 parents of normal children were selected to be included in the control group.After the baseline difference was balanced by PSM 1:1 matching,the general information,scores of parental stress in each dimension and parental stress level of the two groups were compared and analyzed.Single factor analysis was carried out on the factors affecting the parental stress of group;Pearson was used to analyze the correlation between the factors affecting parental stress in MR group.Logistic regression was used to analyze the factors affecting the job stress of parents in MR group.RESULTS After matching,there were 97 cases in both groups.The differences of parents'working status and family location in MR group were statistically significant,P<0.05.Parents in MR group were significantly higher than those in control group in every dimension and total score,of which 75.22%were at a high level,P<0.05.Univariate analysis shows that the older the parents are,the more unstable their work status is,the lower their education level is,the less their family income is,their location is in the countryside and the children have a genetic history,the higher their parental stress score is.Pearson correlation analysis showed that the total score of parental stress was related to supporting friends(r=-0.354),seeking social support,maintaining self-esteem and psychological stability(r=-0.146),coping style frequency(r=-0.476)and role size(r=-0.063).P<0.05.Using the binary Logistic regression model,it was found that whether the child had a genetic history(HR=1.667)was a risk factor affecting the parents'job stress of MR children,and friends'support(HR=0.539),seeking social support(HR=0.478),maintaining self-esteem and psychological stability(HR=0.625),and the frequency and role of coping styles(HR=0.794)were all its protective factors,P<0.05.CONCLUSION Parents'parental stress of most preschool children with MR is at a high level,in which children's genetic history is its risk factor,and friends'support,seeking social support,maintaining self-esteem and psychological stability,as well as the frequency and role of coping styles are its protective factors,which provides new intervention programs and measures to alleviate parents'parental stress of MR children. 展开更多

The amount of root bleeding sap, contents of chlorophyl , nutrients and hormones in flag leaves of a super-hybrid rice cultivar Liangyoupeijiu (LYPJ) and its parents 9311 and Pei’ai 64S after heading were measured in this study. The re-sults revealed that compared with 9311, the chlorophyl content of LYPJ reduced more quickly after heading, and then kept at a lower level, which was an obvious characteristic of premature senescence. The other physiological indices of LYPJ af-ter heading except abscisic acid (ABA) content in leaf and root also maintained at a lower level than 9311, while al the physiological indices of the sterile line Pei'ai 64S were lower than LYPJ. So it was speculated that the early-aging characteristic of LYPJ may be inherited from Pei’ai 64S. Al the leaf and root early-aging traits reduced for LYPJ and its parent lines after heading, their leaf and root aged grad-ual y, which indicated that the above-ground (leaf) and under-ground (root) parts cor-related to each other closely, but there was not absolute correlations between them judged from the data. 展开更多

Sweetpotato varieties with high carotene content have high value for human health. This work aims to improve the breeding efficiency of special varieties with high carotene content by combining molecular markers and agronomic traits to evaluate and screen the parents. The cluster analysis was carried out to identify and screen promising parents by utilizing phenotypic results of the agronomic and characteristic traits, and RAPD and ISSR markers of 15 parents and their offspring by group crossing. Among different parental materials, greater variations were observed in two important traits, the carotene content and the storage root yield. Negative correlation was found between the carotene content and both fresh and dried root yields. The most significant positive correlation was between the carotene content of parents and that of their offspring, with the coefficient of correlation value of 0.7932**. The relationship based on the agronomic characters of the trial materials was not in agreement with the known genealogy, while that based on the molecular marker data showed better result. Each primer amplified 13.8 bands oflSSR markers on average, in which the rate of polymorphic loci was 89.6%. 9.4 bands of RAPD markers were arnplified per primer, in which the rate of polymorphic bands was 74.46%. Large genetic variation of carotene content was found among the parents. For analyzing the genetic diversity of sweetpotato, the molecular marker methods were better than morphological traits; ISSR markers were more efficient than RAPD markers. The combination of molecular markers and agronomic trait analysis may provide valuable theoretic basis for selection of parents to breed new varieties with high carotene content. 展开更多

To study differences and genetic trends of volatiles in Xingdu 1 and Xingdu 2, the strawberry cultivars, with their parents, the volatile components were analyzed by head space-solid phase microextraction and gas chromatography-mass spectrometry. The results indicated that a total of 50 compounds were identified in Xingdu 1 cultivar, including hexanoic acid methyl ester and hexanoic acid ethyl ester, butanoic acid methyl ester, and butanoic acid ethyl ester, octanoic acid methyl ester and octanoic acid ethyl ester, isomyl hexanoate. And there were 71 compounds in Xingdu 2, which were similar to that of Xingdu 1. About 55 volatiles were identified in Allstar (female parent), including acetone, acetic acid 1- methylethyl ester, 1-octanol, hexanoic acid ethyl ester and butanoic acid methyl ester. And 43 volatiles were identified in Toyonoka (male parent), including hexanoic acid ethyl ester, nerolidol, 1-octanol, hexanoic acid methyl ester, acetic acid octyl ester, isomyl hexanoate and octanoic acid methyl ester. Consequently, hexanoic acid methyl ester and hexanoic acid ethyl ester, butanoic acid methyl ester, and butanoic acid ethyl ester and isomyl hexanoate in twins might be affected both sides of their parents. In the family, male parent (Toyonoka) had the highest concentrations of fragrance alcohols, such as nerolidol, linalool and 1-octanol, but which couldn't be transmitted to the descendants. Acetone, acetic acid 1- methylethyl ester of the twins originally came from matrilinear inheritance, as the contents of the two compounds were very high in Allstar but little in Toyonoka. Genetic trends of butanoic acid methyl ester, butanoic acid ethyl ester, hexanoic acid ethyl ester, hexanoic acid methyl ester and isomyl hexanoate were affected by both sides of parents. 展开更多

Forty-one entries were assigned into two clusters (i.e. early or medium-maturing cluster; medium or late-maturing cluster) and further assigned into six sub-clusters based on morphological trait cluster analysis, The early or medium-maturing cluster was composed of 15 maintainer lines, four early-maturing restorer lines and two thermo-sensitive genic male sterile lines, and the medium or late-maturing cluster included 16 restorer lines and 4 medium or late-maturing maintainer lines. Moreover, the SSR cluster analysis classified 41 entries into two groups (i.e, maintainer line group and restorer line group) and seven sub-groups. The maintainer line group consisted of all 19 maintainer lines, two thermo-sensitive genic male sterile lines, while the restorer line group was composed of all 20 restorer lines. The SSR analysis fitted better with the pedigree information. From the views on hybrid rice breeding, the results suggested that SSR analysis might be a better method to study the diversity of parental lines in indica hybrid rice. 展开更多

BACKGROUND Parental behaviors are key in shaping children’s psychological and behavioral development,crucial for early identification and prevention of mental health issues,reducing psychological trauma in childhood.AIM To investigate the relationship between parenting behaviors and behavioral and emotional issues in preschool children.METHODS From October 2017 to May 2018,7 kindergartens in Ma’anshan City were selected to conduct a parent self-filled questionnaire-Health Development Survey of Preschool Children.Children’s Strength and Difficulties Questionnaire(Parent Version)was applied to measures the children’s behavioral and emotional performance.Parenting behavior was evaluated using the Parental Behavior Inventory.Binomial logistic regression model was used to analyze the association between the detection rate of preschool children’s behavior and emotional problems and their parenting behaviors.RESULTS High level of parental support/participation was negatively correlated with conduct problems,abnormal hyperactivity,abnormal total difficulty scores and abnormal prosocial behavior problems.High level of maternal support/participation was negatively correlated with abnormal emotional symptoms and abnormal peer interaction in children.High level of parental hostility/coercion was positively correlated with abnormal emotional symptoms,abnormal conduct problems,abnormal hyperactivity,abnormal peer interaction,and abnormal total difficulty scores in children(all P<0.05).Moreover,paternal parenting behaviors had similarly effects on behavior and emotional problems of preschool children compared with maternal parenting behaviors(all P>0.05),after calculating ratio of odds ratio values.CONCLUSION Our study found that parenting behaviors are associated with behavioral and emotional issues in preschool children.Overall,the more supportive or involved the parents are,the fewer behavioral and emotional problems the children experience;conversely,the more hostile or controlling the parents are,the more behavioral and emotional problems the children face.Moreover,the impact of fathers’parenting behaviors on preschool children’s behavior and emotions is no less significant than that of mothers’parenting behaviors. 展开更多
