Cognitive and social-emotional development in the first three years of life is associated with later skills. However, little is known about the paths of developmental delays in both cognitive and social-emotional skills before age 3 or to what extent these paths predict later developmental outcomes. The aim of this study is to examine the associations between the different paths of developmental delays in both cognitive and social-emotional skills of children before age 3 and the levels of development of the children when they are preschool age. Using a longitudinal data collected at three time points from 1245 children and their caregivers in rural China, we identified four different paths of developmental delays in cognitive and social-emotional before age 3 and examined how these paths are associated with different levels of developmental outcomes at preschool age. We used a non-parametric standardization approach and an ordinary least squares model to perform our analyses. Findings show that rates of developmental delays in either cognitive or social-emotional domain or both domains are high at all different time points, ranging from 20% to 55% for cognitive delays and 42% to 61% for social-emotional delays. Over half of children experienced deteriorating levels of either cognitive or social-emotional development before age 3. A large share of children was found to be persistently delayed in either domain. Only a small share of children raised their levels of development in either domain before age 3. In addition, we identified certain socioeconomic status of the family that are associated with never or deteriorating path of child developmental delays. More importantly, we revealed that different paths of developmental delays before age 3 have predictive power on different levels of developmental outcomes at preschool age. Our results suggest that actions are needed at the earliest times to improve child development when children are still infants or toddlers.

Background: The association between sleep patterns and young students’ mental health, which is crucial for their development, remains understudied in rural China. Therefore, the relationship between sleep patterns and mental health among primary and junior high school students in rural China was examined. Method: A total of 1592 primary and junior high school students from rural areas of Gansu Province were surveyed, and the Depression Anxiety and Stress Scale (DASS) was utilized to assess mental health, alongside self-reported data on their daily sleep patterns. Results: Significant sleep inadequacies were identified: 28% of students received less than 8 h of sleep on weekdays, and 19% went to bed later than recommended. On weekends, 38% of students had delayed bedtimes, though only 7.2% received less than 8 h of sleep. Notably, a “U-shaped” relationship was uncovered between sleep duration and mental health for students on weekends, with optimal mental health correlated with receiving 10–11 h of sleep, while both shorter and longer sleep durations on weekends worsened outcomes. This pattern is absent on weekdays. Additionally, adequate sleep and an earlier bedtime was linked to a 6–8% decrease in mental health risks. Conclusions: These findings provide valuable insights for policymakers seeking to enhance student mental well-being in rural settings, emphasizing the importance of implementing measures that promote balanced sleep habits among young students.

Background
Comorbidity in mental disorders is prevalent among adolescents, with evidence suggesting a general psychopathology factor (“p” factor) that reflects shared mechanisms across different disorders. However, the association between the “p” factor and protective factors remains understudied. The current study aimed to explore the “p” factor, and its associations with psycho-social functioning, in Chinese adolescents.

Methods
2052 students, aged 9–17, were recruited from primary and secondary schools in Shanghai, China. Multiple rating scales were used to assess psychological symptoms and psycho-social functioning. Confirmatory factor analysis was conducted to verify the fit of models involving different psychopathology domains such as externalizing, internalizing, and the “p” factor. Subsequently, structural equation models were used to explore associations between the extracted factors and psycho-social functioning, including emotion regulation, mindful attention awareness, self-esteem, self-efficacy, resilience, and perceived support.

Results
The bi-factor model demonstrated a good fit, with a “p” factor accounting for 46 % of symptom variation, indicating that the psychological symptoms of Chinese adolescents could be explained by internalizing, externalizing, and the “p” factor. Psychologically, a higher “p” was positively correlated with emotion suppression and negatively correlated with mindful attention awareness, emotion reappraisal, self-esteem, and resilience. Socially, a higher “p” was associated with decreased perceived support.

Limitations
Only common symptoms were included as this study was conducted at school. Furthermore, the cross-sectional design limited our ability to investigate causal relationships.

Conclusions
A “p” factor exists among Chinese adolescents. Individuals with higher “p” factor levels were prone to experience lower levels of psycho-social functions.

Purpose
China’s rapid urbanization has been associated with increased mental health challenges, especially in rural-to-urban migrant children. This study evaluates the effects of mindfulness and life-skills (LS) training on emotional regulation and anxiety symptoms from a randomized controlled trial aimed at improving the mental health of Chinese migrant children.

Methods
Two intervention arms—mindfulness training (MT) and MT plus LS mentorship (MT + LS)—were compared to a waitlist control group of 368 migrant children aged 9–17 years. Volunteers were trained to deliver interventions to 285 migrant children in small groups of 15 for eight weeks weekly. Social integration varied: migrant children mixed with local children at public schools were considered highly integrated, those in migrant-only classrooms at public schools had intermediate levels of integration, and children in private migrant schools had low integration. Emotion regulation and anxiety symptoms were assessed preintervention, postintervention, and three months postintervention.

Results
Postintervention and compared to the control group, children with high social integration in the MT arm showed increased cognitive reappraisal ability (p < .05) but higher physical anxiety (p < .01). Children with high social integration in the MT + LS arm had lower anxiety symptoms of harm avoidance (p < .01) and physical anxiety (p < .05). Children with low social integration in the MT + LS arm showed lower cognitive reappraisal (p < .01) and poorer overall emotion regulation abilities (p < .01). Three months later, children with intermediate integration in the MT + LS arm had lower separation anxiety (p < .05) and harm avoidance anxiety (p < .05). No other groups showed significant improvements in emotion regulation or reducing in anxiety symptoms three months postintervention.

Discussion
Mindfulness and LS training may benefit Chinese migrant children who have higher levels of social integration but increase anxiety in those with lower social integration. Future research should consider the sociocultural context in which a treatment is implemented.

Childhood is a crucial period of psychological and social development, rendering individuals susceptible to developing mental health issues. Unfortunately, many countries around the world, including China, are facing a shortage of child psychiatrists, which is a significant concern. This Comment was conducted to clarify the current number of child psychiatrists in mainland China, to analyze the reasons for the shortages and to provide constructive suggestions for solving the current shortage.

Background: To explore the associations between anxiety and depression symptoms and academic burnout among children and adolescents in China, and to examine the role of resilience and self-efficacy in addressing academic burnout.

Methods: A total of 2,070 students in grades 4–8 were recruited from two primary and three middle schools in Shanghai, completed the Elementary School Student Burnout Scale (ESSBS), the Multidimensional Anxiety Scale for Children-Chinese (MASC-C), the Center for Epidemiological Studies Depression Scale (CES-D), the Connor-Davidson Resilience Scale (CD-RISC), and the General Self-Efficacy Scale (GSES), with 95.04% effective response rate. Multivariable regression analyses examining the associations between anxiety / depression symptoms and academic burnout (as well as the associations between resilience / self-efficacy and academic burnout) were performed using STATA 16.0 and SmartPLS 3.0.

Results: Anxiety symptoms (β = 0.124, p < 0.01) and depression symptoms (β = 0.477, p < 0.01) were positively correlated with academic burnout. Resilience partially mediated the association between depression symptoms and academic burnout (β = 0.059, p < 0.01), with a mediation rate of 12.37%. Self-efficacy partially mediated the associations between anxiety symptoms and academic burnout (β = 0.022, p < 0.01) and between depression symptoms and academic burnout (β = 0.017, p < 0.01), with mediation rates of 17.74% and 3.56%, respectively. Resilience and self-efficacy together (β = 0.041, p < 0.01) formed a mediating chain between depression symptoms and academic burnout, with a mediation rate of 8.6%.

Conclusions: Anxiety and depression symptoms were positively associated with academic burnout. Resilience and self-efficacy were found to mediate the associations partially.

Background: Maternal empowerment - the capacity to make decisions within households - is linked to better child feeding and nutritional outcomes, but few studies have considered the mediating role of caregiver knowledge. Further, existing literature centres primarily on the husband-wife dyad while overlooking grandmothers as important childcare decision-makers.

Methods: We collected primary data through household surveys in 2019 and 2021 from 1190 households with infants zero to six months living in rural western China. We identified the primary and secondary caregivers for each infant and assessed their feeding knowledge and practices, as well as infant nutritional status. We constructed a maternal empowerment index using a seven-item decision-making questionnaire and examined the relationship between maternal empowerment in childcare and household decisions, caregivers' feeding knowledge, and infant feeding practices and nutritional outcomes.

Results: Mothers had significantly higher levels of feeding knowledge than secondary caregivers (most were grandmothers, 72.7%), with average knowledge scores of 5.4 vs. 4.1, respectively, out of 9. Mothers and secondary caregivers with higher levels of feeding knowledge had significantly higher exclusive breastfeeding rates by 13-15 percentage points (P < 0.01) and 11-13 percentage points (P < 0.01), respectively. The knowledge of secondary caregivers was even more strongly associated with not feeding formula (15 percentage points, P < 0.01). Mothers empowered to make childcare decisions were more likely to exclusively breastfeed (12-13 percentage points, P < 0.01), less likely to formula feed (9-10 percentage points, P < 0.05), and more likely to have children with higher Z-scores for length-for-age (0.32-0.33, P < 0.01) and weight-for-age (0.24-0.25, P < 0.05). Effects remained after controlling for maternal feeding knowledge.

Conclusions: While mothers' and grandmothers' feeding knowledge was both important for optimal infant feeding, grandmothers' knowledge was particularly critical for practicing exclusive breastfeeding. Given the disparity in feeding knowledge between the two caregivers, our study further shows that mothers empowered in childcare decision-making were more likely to exclusively breastfeed their infants. This implies that some mothers with adequate knowledge may not practice optimal feeding because of lower decision-making power. Overall, our study highlights the role of secondary caregivers (grandmothers) in infant care and suggests that future child nutritional interventions may benefit from involving secondary caregivers (grandmothers).

Background
Mental health problems among children at preschool age are a common issue across the world. As shown in literature, a caregiver’s parenting style can play a critical role in child development. This study aims to examine the associations between a caregiver’s parenting style and the mental health problems (or not) of their child when he/she is at preschool age in rural China.

Methods
Participants were children, aged 49 to 65 months, and their primary caregivers. The primary caregivers of the sample children completed the Parenting Styles and Dimensions Questionnaire, Short Version, the Strengths and Difficulties Questionnaire, and a questionnaire that elicited their socio-demographic characteristics. The level of cognitive development of each sample child was assessed using the Wechsler Preschool and Primary Scale of Intelligence, Fourth Edition. Pearson correlation analysis, linear regression analysis, and multivariable regression analysis were used to analyze the data.

Results
The prevalence of mental health problems among sample children at preschool age was high (31.6%). If a caregiver practices an authoritative parenting style, it was found to be negatively associated with the mental health problems of their child. In contrast, a caregiver’s authoritarian parenting style was positively associated with the mental health problems of their child. Compared to those in a subgroup of primary caregivers that used a combination of low authoritative and low authoritarian parenting style, primary caregivers that used a combination of high authoritarian and low authoritative or a combination of high authoritative and high authoritarian were found to have positive association with child health problems. A number of demographic characteristics were found to be associated with the adoption of different parenting styles.

Conclusion
Different parenting styles (including authoritative, authoritarian, and combination of authoritative and authoritarian) of the sample caregivers had different associations with the mental health problems of the sample children. Parenting programs that aim to improve the parenting styles (favoring authoritative parenting styles) should be promoted in an effort to improve the status of child mental health in rural China.

Objectives
Patient satisfaction is an essential indicator of the doctor-patient relationship. This study aimed to investigate the relationship between primary care quality and patient satisfaction for non-communicable diseases (NCDs) in rural western China.

Methods
The study utilized the standardized patients (SPs) approach to present typical symptoms of unstable angina and diabetes to rural healthcare providers. After the consultations, the SPs completed a satisfaction survey. Ordinary least squares and quantile regression were used to examine the association between quality of primary care and patient satisfaction.

Results
We examined 178 anonymous SPs visits. The results showed that higher process quality for angina SPs was correlated with stronger satisfaction for provider ability at a low quantile of ability satisfaction. For diabetes SPs, higher process quality increased overall satisfaction at a low quantile of overall satisfaction, whereas a correct diagnosis significantly contributed to communication satisfaction at a high quantile of communication satisfaction.

Conclusions
The study found positive associations between process and diagnosis quality and SPs satisfaction. Notably, the influence of process quality was most significant among patients with lower satisfaction levels.
