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.

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.

Objective To investigate factors that differentiate elderly adults in rural China who accept free vision screening and cataract surgery from those who could benefit from vision care but refuse it when offered.

Design We conducted a population-based, cross-sectional study between October and December 2016. Logistic regression models were used to examine the predictors of accepting free vision screening and cataract surgery.

Setting Rural communities in Handan, China.

Participants Adults aged 50 years or older, with presenting visual acuity ≤6/18 in the better seeing eye, suspected by examining ophthalmologist to be due to cataract.

Results Among 613 persons with cataract identified on a population basis, 596 (97.2%) completed the household survey (mean (SD) age, 71.5 (10.0) years; 79.8% female). A total of 214 persons (35.9%) refused participation, while 382 (64.1%) took part in the vision screening. A total of 193 (50.5%) participants were found eligible for surgery, while 189 (49.5%) were not. Among 99 randomly selected participants who were offered immediate free surgery, surgery was accepted by 77 participants (77.8%) and refused by 22 (22.2%). In the multivariate model, being engaged in income-generating activities (p<0.01), self-reported better physical capacity (p<0.001) and having had a recent physical examination (p=0.01) were significantly associated with acceptance of vision screening. The only variable significantly associated with acceptance of surgery was presenting visual acuity, with better vision inversely associated with acceptance of surgery (p<0.05) models.

Conclusion Our results suggest that refusal of basic eye examinations may be at least as important a determinant of low surgical rates in rural China as lack of acceptance of surgery itself.
