Background: Childhood trauma is a potential threat to depression and can have a lifelong impact on the mental health of university students. Our study aimed to construct a moderated mediation model to explore the relationship between childhood trauma, psychache, ambivalence over emotional expression, physical activity, and depression in university students. Methods: A cross-sectional study was conducted in three universities in China, recruiting 476 university students using self-report questionnaires. The moderated mediation model was examined using the SPSS PROCESS model 21. Results: Ambivalence over emotional expression (F=12.843), childhood trauma (F=117.639), and psychache (F=581.594) all had a significant positive effect on depression (p<0.001), explaining 2.9%, 21.7%, and 56.8% of the variance, respectively. On the chain of influence between childhood trauma and depression, the mediating effect of psychache, the moderating effect of ambivalence over emotional expression, and the moderating effect of physical activity are all significant the overall indirect effect value of the three is 0.287, accounting for 61.59% of the total effect. Conclusion: This study investigated the relationship between childhood trauma, ambivalence over emotional expression, psychache, physical activity, and depression in university students. Future interventions should focus on developing good emotional expression among university students, increasing opportunities for physical activity, and reducing psychache to reduce depression.

Background: Meaning in life is a widely accepted aim in promoting psychosocial health in institutional care. However, how caregiver interaction and perceived control impact meaning in life among the elderly remains unclear. This study explores the effect of institutional caregiver interaction, family caregiver interaction, and perceived control on meaning in life among elderly residents in China, and the potential moderating effect of elderly-to-social worker ratio in these associations. Methods: Multistage random sampling was used to recruit a sample of 452 elderly residents from 4 elderly care homes in urban China. A structural equation model was used to test the study hypothesis. Results: Institutional caregiver interaction is positively related to meaning in life, and perceived control among elderly residents has a positive impact on meaning in life. Moreover, the elderly-to-social worker ratio moderated the relationship between institutional caregiver interaction and meaning in life, as well as between family caregiver interaction and meaning in life. Conclusions: Increase elderly's meaning in life is an important service target for the caring professions in institutional care. Social workers affect the effectiveness of interventions on elderly's meaning in life in institutional care. A higher elderly-to-social worker ratio could improve the effectiveness of interventions on meaning in life for elderly residents. [ABSTRACT FROM AUTHOR]

Background: Campus lockdown orders were issued for the purpose of preventing and controlling COVID-19, which resulted in psychological problems among college students. However, the experiences they have during the pandemic may also lead to positive personal changes, including posttraumatic growth (PTG). The current study examined the mediating role of belief in a just world and meaning in life in social support and PTG during the COVID-19 campus lockdown. Method: An online survey was conducted on 1711 college students in Hebei Province, China. Based on the survey results, a structural equation model was established. Results: Social support positively predicted PTG. Furthermore, belief in a just world and meaning in life played a mediating role between social support and PTG respectively. Besides, social support could also predict PTG through the multiple serial mediating effect of belief in a just world and meaning in life. Conclusion: These results indicated mechanisms by which social support influenced PTG, and this provided insights into how to promote post- traumatic growth among university students in the post-pandemic period.

Given that the field of work-family conflict is overwhelmingly Western-focused and that the process of work-family conflict might change under a different cultural background, the aim of the present study was to develop and test an integrated work-family conflict model that is applicable in China. Using a sample of 520 Chinese participants and structural equation modelling in R studio, the differences between the present study and previous Western findings were spotted. The results revealed that family support was positively related to time spent on family responsibilities and negatively related to life satisfaction; only work-to-family conflict, but not family-to-work conflict, had three forms of unique antecedent (time-, strain-, behavioural-based); and more surprisingly, work-family conflict was positively related to life satisfaction in China. This study refined our understanding of work-family conflict and enriched our knowledge of how work-family conflict acted in China's work-family interface, providing directions for future cross-cultural work-family conflict studies.

As a severe public health concern directly endangering life safety, adolescent suicide has been extensively investigated in variable-centered studies. However, gaps remain in the knowledge of heterogeneous suicide risk patterns and their developmental nature. Additionally, little is known about protective factors associated with suicide risk patterns and changes. This study applied person-centered approaches to explore suicide risk profiles and transitions over time in early Chinese adolescents, along with their protective factors. A total of 1518 junior high school students (49.6% girls, Mage = 13.57, SD = 0.75) participated in two surveys within a 12-month interval. Latent Profile Analysis and Latent Transition Analysis were used to model the profiles and transitions of suicide risk. Three risk profiles were identified at both time points: low risk profile (73.9, 78.3%), medium risk-high threat profile (16.2, 10.2%), and high risk profile (9.9, 10.2%). Low risk profile was stable, while medium risk-high threat and high risk profiles showed great transitions over 12 months. Sense of control, meaning in life, and regulatory emotional self-efficacy served as protective factors against suicide risk profiles and transitions. Findings underscore the importance of comprehensively illustrating suicide risk states from multiple aspects, as well as understanding the fluid nature of transitions between different risk states. Prevention and intervention strategies aimed at enhancing resilience, such as increasing sense of control, perceived meaningfulness, and belief in emotional regulation, may contribute to reducing the risk of suicide among adolescents.

During the initial outbreak of COVID-19 in China, people spent a lot of time viewing or listening to COVID-19-related media content. And according to the conservation of resources theory, COVID-19-related media exposure would be related to multiple psychological outcomes, and different contents would have different associations with different psychological outcomes. Therefore, the present study aimed to clarify these relationships and find out the most important psychological outcome correlated with COVID-19-related media exposure. An online survey was conducted to collect information about individuals' media use behaviors and mental health status. A total of 917 participants were included in further analyses. The results proved that different kinds of content had different relationships with different psychological outcomes. To be more specific, the content about people being heroic and speeches from experts and the authorities were related to increases of positive affect, while reports from hospitals were correlated with increases of death anxiety. Moreover, positive affect was central nodes of the network. The current findings indicated viewing objective and positive content was associated with positive psychological outcomes while viewing negative one was correlated with negative psychological outcomes. Furthermore, positive affect was the most important psychological outcome related to COVID-19-related media exposure. [ABSTRACT FROM AUTHOR]

This study investigated the trajectories in posttraumatic growth (PTG) among adolescents who survived from the Yancheng tornado in China, and explored the effects of posttraumatic stress symptoms (PTSS) on these trajectories. Participants (n = 246) finished 4 assessments at 6, 9, 12, and 18 months after the tornado. Growth mixture model and logistic regression were used to examine the heterogeneous trajectories and the role of PTSS for differentiating trajectories respectively. Two latent PTG trajectories were observed: group with decreasing PTG and group with fluctuant PTG, which might stem from the illusory component and the factual component of PTG respectively based on the two-component model; and adolescents with more PTSS had higher probabilities generating decreasing PTG, that is, illusory PTG. This study suggested differentiating PTG trajectories and related influencing factors to improve the post-disaster psychological interventions in a longitudinal perspective. [ABSTRACT FROM AUTHOR]

Drawing upon the stress buffering model of social support, this study investigated how perceived social support (PSS), defined as the amount of support individuals think they can mobilize from their network, and received social support (RSS), defined as the level of support individuals have received, moderated the direct and indirect relationships between COVID-19 news exposure (i.e., stressor) and stress via social trust. An online survey from six major cities in China (N = 636) revealed that PSS rather than RSS moderated the direct relationship between COVID-19 news exposure and stress such that this relationship was stronger at a low level of PSS than a high level. Additionally, RSS rather than PSS moderated the relationship between COVID-19 news exposure and social trust such that this relationship was stronger at a low level of RSS than a high level. These findings reveal the differential mechanisms by which PSS and RSS function to buffer against stress. [ABSTRACT FROM AUTHOR]

We set out to understand how role-making works and what roles employees and leaders play in this process. Employees often make changes to their work roles, such as by negotiating their job responsibilities and seeking challenging tasks. In this study, we suggest that role-making behaviours influence and are influenced by the dyadic relationship between leaders and employees, otherwise known as leader–member exchange (LMX). We collected three waves of survey data from a sample of Chinese employees who were recent college graduates (n = 203). The results from cross-lagged panel analyses showed that (1) LMX and job-change negotiation were reciprocally related to each other and (2) initial LMX was associated with increased challenge-seeking behaviours, although these behaviours did not lead to greater LMX later on. In addition, we found evidence that when employees experienced a high level of emotional ambivalence (a conflicting, mixed and complex emotional state), the direct and reciprocal relationships between LMX and role-making behaviours were weakened. Our findings advance the understanding of the development of leader–employee relationships in the workplace and have implications for strengthening employee perceptions of high-quality relationships with their leaders by making changes to their workplace roles.

Based on the model of proactive motivation and the conservation of resources (COR) theory, the current study examines how workplace ostracism as a negative relational context influences feedback-seeking behavior (FSB) and whether personal (i.e., loss-focused coping orientation) and condition resources (i.e., supervisor and spousal support) can buffer the detrimental impacts of workplace ostracism on employees. Using a sample of 506 employees from China, we employed the PROCESS macro to examine our hypotheses. The results showed that workplace ostracism had a negative indirect impact on FSB by reducing vitality. Employees' personal and condition resources also weakened the direct detrimental impact of workplace ostracism on vitality as well as its indirect impact on FSB (i.e., moderated mediation effects). This study extends the relational antecedents of FSB by examining workplace ostracism. More importantly, we provide a resource perspective to interpret how and when workplace ostracism influences FSB, moving beyond the dominant cost-value framework in the FSB literature.

Moral sensitivity of individuals plays a crucial role in the prediction of moral behavior, but the moral values of Chinese culture are different from the west, and we need a simple way to measure the moral sensitivity of Chinese people. This study puts forward a method for measuring the moral sensitivity of Chinese individuals from the perspective of the levels of the moralization model. The sample in the study 1 included 21,054 Chinese persons aged between 18 and 95. Through exploratory factor analysis, we established a model of the scale and verified the stability and invariance of the model across gender and age through confirmatory factor analysis and multi-group confirmatory factor analysis. Study 2 included a sample of 1951 primary, middle and high school students between the ages of 8 and 19. By means of confirmatory factor analysis, we again verified the factor structure of this questionnaire, and used a series of moral emotion questionnaires (Three Domains of Disgust Scale, Gratitude Questionnaire, Dispositional Positive Emotion Scales, Dispositional Greed Scale) to verify the structural validity. The results of confirmatory factor analysis showed that the goodness-of-fit indices fits well. The multi-group confirmatory factor analysis suggested that configural, metric, scalar, and error variance invariance holds across genders and age groups. The results of the latent mean difference test showed that the latent mean scores were comparable between genders and age groups. The results of correlational analysis show that the scale has a high structural validity. In conclusion, the results of this study showed that the moral sensitivity scale has high reliability and validity in Chinese people. [ABSTRACT FROM AUTHOR]

Objectives: ST11 KPC-producing Klebsiella pneumoniae (Kp) is highly prevalent in China. We investigated the inter- and intra- host transmission and evolution characteristics of ST11 KPC-producing Kp. Methods: A retrospective study was conducted in a hospital. The clinical data and antimicrobial resistance (AMR) phenotypes were collected. Whole genome sequencing was performed. The transmission route was reconstructed by combining single nucleotide polymorphisms (SNPs) with the clinical information. Hypervirulent Kp (HvKp) was defined as the presence of some combination of peg-344, iroB, iucA, rmpA, or rmpA2. Results: Fifty-eight Kp strains isolated from thirty-five patients were enrolled. The information of one isolate was missing. The mean age of the patients was 74.3 ± 18.0 years, and 18 (50.0%) were female. Fifteen patients (41.7%, 15/36) presented with poor prognosis. All the strains were identified as ST11, and 57 strains harbored blaKPC-2. Two distinguished clades were identified based on the 1,325 high quality SNPs. In clade 1, carbapenem-resistant (CR)-hvKp accounted for 48.3% of the strains (28/58), which mostly presented as KL64 subclones, whereas CR-classical Klebsiella pneumoniae (cKp) commonly possessing KL47 were clustered in Clade 2. One CR-hvKp strain might have originated from the CR-cKp strain from within-host evolution. Even worse, a prolonged transmission of CR-hvKp has led to its spread into healthcare institutes. Conclusion: Two endemic subclones of ST11 KPC-producing Kp, KL64-CR-hvKp and KL47-CR-cKp, were transmitted in parallel within the hospital and/or the healthcare institute, suggesting that the ongoing genomic surveillance should be enhanced.

Background: Psychological well-being plays a vital role in nursing students' mental health and affects their decisions to stay in the nursing profession, particularly during the COVID-19 outbreak. Close relationships are undeniably linked to psychological well-being, but it is unknown how the specific pathways through which close relationships are related to each other and which are most strongly linked to nursing students' psychological well-being. Aims: To explore the network structure, central and bridge factors among well-being characteristics, and predictors based on a model of thriving through relationships. Methods: A cross-sectional research design was used with a sample of undergraduate nursing students (531 participants from the Southwest part of China). We used a network model to analyze the network structure of perceived social support, mindfulness, self-integrity, self-compassion, professional self-concept, savoring, intentional self-regulation, non-relational self-expansion, relational self-expansion, attachment insecurity, and psychological well-being. Results: A highly interconnected network of psychological well-being featured predictors and traits were formed. Node 8 (self-kindness), node 9 (self-judgment), and node 23 (non-relational self-expansion) were the predictors with the highest centrality in the network. Perceived social support and professional self-concept were most central in linking predictors to psychological well-being traits. Attachment insecurity was a non-supportive factor for predicting psychological well-being among female nursing students. Conclusions: Interventions based on these supportive/non-supportive predictors, which operate on different psychological levels, hold promise to achieve positive effects on psychological well-being among nursing students.

By using data from the Chinese Longitudinal Healthy Longevity Survey from 2002 to 2014, this paper investigates the impact of long-term military service on the life satisfaction of Chinese male elderly individuals for the first time. The results show that compared to nonfarmers, long-term military service significantly reduces the life satisfaction of elderly individuals, which is supported by a series of robustness tests. In addition, we provide evidence that health impairment and insufficient income are the main factors leading to the decline in life satisfaction of elderly veterans. Worse, we find that several social security methods have little effect on promoting the life satisfaction of elderly veterans. Our findings illustrate that the loss of human capital is the leading cause of the decline in the life satisfaction of elderly Chinese veterans. Therefore, it is necessary to strengthen the social security and social benefits of elderly veterans. [ABSTRACT FROM AUTHOR]

Background: Anemia is a common risk factor for post-percutaneous coronary intervention (PCI) adverse events; however, data on its association with in-stent restenosis (ISR) is limited.Methods: 538 patients who underwent PCI between January 2017 and September 2019 and follow-up angiography 9-12 months after the initial PCI were enrolled in this study. Baseline clinical and procedural characteristics were compared between the ISR and non-ISR groups, and independent predictors of ISR were determined using propensity score matching.Results: The incidence of anemia was 53.5% in patients with ISR and 19.0% in those without ISR. Univariable logistic regression analyses showed that anemia (OR, 4.283; 95% CI, 1.949-9.410; P < 0.001), diabetes mellitus (OR, 2.588; 95% CI, 1.176-5.696; P = 0.018), chronic kidney disease (OR, 3.058; 95% CI, 1.289-7.252; P = 0.011), multiple stenting (OR, 2.592; 95% CI, 1.205-5.573; P = 0.015), bifurcation lesion (OR, 2.669; 95% CI, 1.236-5.763; P = 0.012), and calcification (OR, 3.529; 95% CI, 1.131-11.014; P = 0.030) were closely associated with ISR. Low-density lipoprotein cholesterol (LDL-c) levels and stent diameter were also significantly linked to ISR, as was anemia (P = 0.009) after propensity score matching.Conclusion: Anemia is closely associated with post-PCI ISR, and patients with lower hemoglobin levels are at a higher risk of ISR.

Introduction: The increasing trend of synthetic drug use has been a significant concern in China. The current research adopted a gendered perspective to examine the effects of self‐control, drug‐use peers and family attachment on drug use frequency in China. Methods: This cross‐sectional survey research recruited 785 people who used drugs from four compulsory drug rehabilitation institutions in Guangdong and Shandong Province of China in 2018. Ordinary least squares regression analyses were conducted to examine the gendered effects of self‐control (Grasmick et al.'s cognitive scale), drug‐use peers and family attachment on drug use frequency. Results: Low self‐control was neither a significant nor gendered predictor of drug use frequency when controlling for effects of drug‐use peers and family attachment. Drug‐use peers strongly increased participants' drug use frequency, regardless of gender. However, an important finding is that for males, support from families reduced drug use frequency but conversely meeting and contact with families increased drug use frequency. For females, only trust in families prevented their further involvement in drug use. Discussion and Conclusions: Low self‐control may not be a core explanatory factor for drug use behaviours in China. Thus, treatment programs should focus more on skills building than self‐control. Future programs could focus more on reducing association with their drug‐use peers and further explore the complex relationships with their families. Gender should be considered in treatment options.

Background: The novel coronavirus SARS-CoV-2 (coronavirus disease 2019, COVID-19) has caused serious consequences on many aspects of social life throughout the world since the first case of pneumonia with unknown etiology was identified in Wuhan, Hubei province in China in December 2019. Note that the incubation period distribution is key to the prevention and control efforts of COVID-19. This study aimed to investigate the conditional distribution of the incubation period of COVID-19 given the age of infected cases and estimate its corresponding quantiles from the information of 2172 confirmed cases from 29 provinces outside Hubei in China.Methods: We collected data on the infection dates, onset dates, and ages of the confirmed cases through February 16th, 2020. All the data were downloaded from the official websites of the health commission. As the epidemic was still ongoing at the time we collected data, the observations subject to biased sampling. To address this issue, we developed a new maximum likelihood method, which enables us to comprehensively study the effect of age on the incubation period.Results: Based on the collected data, we found that the conditional quantiles of the incubation period distribution of COVID-19 vary by age. In detail, the high conditional quantiles of people in the middle age group are shorter than those of others while the low quantiles did not show the same differences. We estimated that the 0.95-th quantile related to people in the age group 23 ∼55 is less than 15 days.Conclusions: Observing that the conditional quantiles vary across age, we may take more precise measures for people of different ages. For example, we may consider carrying out an age-dependent quarantine duration in practice, rather than a uniform 14-days quarantine period. Remarkably, we may need to extend the current quarantine duration for people aged 0 ∼22 and over 55 because the related 0.95-th quantiles are much greater than 14 days. [ABSTRACT FROM AUTHOR]

Biopesticides have proven to be suitable for the control of agricultural diseases and insects. Natural products and micro-organisms have been used as biopesticides worldwide as they can be sourced from the environment, they are generally safe to non-target organisms including humans, they have reduced persistence in the environment, and they are potentially acceptable for use in organic agriculture. Compared with synthetic pesticides, new biopesticides can gain regulatory approval faster. They can also be developed in less time and are much less expensive to develop. In China, some biopesticides currently being developed may be suitable alternatives to chemical pesticides such as Bacillus thuringiensis, Jinggangmycin, pyrethrins and brassinolide. This review summarizes the mode of action of biopesticides and describes their current development for use in agriculture. [ABSTRACT FROM AUTHOR]

The purpose of this study is to systematically investigate the individual-differences factors related to time awareness in everyday life. Three hundred and nine individuals in China, from 14- to 75-year old, were sampled to complete a questionnaire that consists of instruments measuring time awareness, meaning in life, achievement motivation, affective state and perceived remaining lifetime. The results showed that meaning in life positively predicted present passage-of-time judgment but not retrospective passage-of-time judgment. Meaning in life mediated the effects of achievement motivation and affective state on present passage-of-time judgment. Moreover, perceived remaining lifetime played a role in the associations by moderating the effect of achievement motivation on meaning in life. The findings aligned with socioemotional selectivity theory, which explains that people shift from knowledge-related goals to emotion-related goals as the end of life becomes imminent.

The illicit supply of new psychoactive substances (NPS) in and from China has become a global concern. In line with the international prohibitionist regime, China has instituted a "zero tolerance" supply reduction policy, enacted various laws to regulate controlled substances, and punished related criminal behaviors severely. However, how the NPS supply is organized and how the national laws are interpreted and implemented at the local level have rarely been addressed. Data from qualitative interviews with governmental and judicial actors are used to investigate the experiences concerning the illicit supply of methcathinone and the dynamic ways in which drug policy and laws are implemented practically. Findings show the significance of Changzhi city as a distribution center for illicit supply of methcathinone, the fixed supply patterns, the prioritized measures for controlling methcathinone supply and demand, and the personal strategies used by individual actors to cope with political pressures and job requirements. This study concludes that the unbalanced coexistence of campaign-style and conventional governance results in active institutional arrangements and passive personal strategies in implementing the drug policy and further contributes to a discrepancy between policy formulation and its implementation in practice.

The study aimed to evaluate the effects of an expressive writing intervention on quality of life (QoL) among mainland Chinese breast cancer patients. A total of 118 Chinese breast cancer patients were randomly assigned to one of four groups: a cancer-facts writing condition (CTL group), an emotional disclosure writing condition (EMO group), a self-regulation writing condition (SR group), or a neutral control condition with no writing tasks (CON group). QoL was assessed by FACT-B at baseline, 3-, and 6-month follow-ups. A repeated measure analysis of variance revealed significant effects of time (F = 13.9, P < 0.001, η2 = 0.20) and the time × group interaction (F = 3.5, P < 0.01, η2 = 0.08) on QoL. Residualized change models showed that the CTL, EMO and SR groups reported higher levels of QoL than the CON group at the 6-month follow-up. The EMO group had a higher level of QoL than the SR group. The CTL group had higher level of physical well-being compared to the SR group. Mainland Chinese breast cancer patients shortly after diagnosis benefit from expressive writing. They benefited more from cancer-facts and emotional disclosure compared to self-regulation. The study indicated that the impact of expressive writing may differ due to stage of cancer survivorship, social, and cultural context. [ABSTRACT FROM AUTHOR]

This paper examines the moderating effect of positive reciprocity beliefs and the mediating effect of interpersonal trust on the relationship between proactive personality and individual life satisfaction in China. In study one, 371 employees completed a survey, the results of which showed that proactive personality was positively related to employee life satisfaction; however, positive reciprocity beliefs did not moderate this association. In study two, 244 Chinese adolescents completed a two-wave survey with a 4-month interval. These results also confirmed that proactive personality was positively related to individual life satisfaction, and interpersonal trust mediated the association. Positive reciprocity beliefs moderated the effect of proactive personality on interpersonal trust and, furthermore, moderated the mediating effect of interpersonal trust on the relationship between proactive personality and life satisfaction. The findings, theoretical contributions, and practical implications of the present paper are discussed further. [ABSTRACT FROM AUTHOR]

Background: The key factors of inducing drug cravings in persons abstaining from drug use remain a focus of addictions research. Given the accumulating evidences, the scope of cues investigated in the cue-reactivity paradigm has increased considerably. Yet, few studies have examined the effects of the intensity and endurance of different types of cues on their ability to induce craving. This study investigated differences among drug-cue words, negative physiological-cue words, and negative social-cue words in the induction of drug cravings among persons abstaining from heroin. Methods: The sample consisted of 149 male abstinent heroin abusers from four addiction rehabilitation centers in China. Based on their abstinence lengths, they were labeled as short-term, medium-term, and long-term abstainer participants respectively. All participants completed a stress-imagery task and rated craving by visual analog scale. Results: There was a significant interaction of cue type and abstinence length. There was no difference on the craving induced by three types of cue words in the short-term group. In the medium-term group, craving induced by negative social-cue words was significantly stronger than that by negative physiological-cue words, but not that by drug-cue words. In the long-term group, the craving induced by negative social-cue words remained the strongest, significantly stronger than that by both drug-cue words and negative physiological-cue words. Conclusion: Negative social-cue words presented in the current study retain the ability to induce craving in heroin abstainers; this finding suggests that negative social cues encountered under more general circumstances could be a risk factor for relapse.

PM2.5 (Fine particulate matter in the atmosphere) pollution has become a major problem affecting human health and social development, especially in developing countries like China. The interaction between PM2.5 and the underlying factors across different regions or spatial scales are very complex, so it is helpful to study the spatial distribution and evolution of PM2.5, which is the foundation for carrying out regional collaborative governances. However, there is a paucity of this kind of research in China. This paper tries to put forward a new multi-scalar framework based on the spatiotemporal synthesis. After the spatial distribution and evolution of PM2.5 data is integrated with the methods of remote sensing, geographic information system and social ecological system analysis, we can more properly describe the evolving trajectory and characteristics of PM2.5 at different time–space scales. The paper defines and divides the space influenced by PM2.5 into four categories, which indicate the paths of spatial diffusion and finally puts forward the methodology of regional collaboration and environmental governance.

Due to successful public health campaigns, breast cancer has successfully transformed from a highly stigmatized illness to a philanthropically supported disease in the United States. However, Chinese American breast cancer survivors continue to experience high levels of self-stigma and associated negative mental health outcomes. In the present study, we examined the relations between self-stigma and depressive symptoms, and further tested individual difference variables such as ambivalence over emotional expression and intrusive thoughts that may exacerbate the harmful effects of self-stigma among this population. One hundred and twelve foreign-born Chinese breast cancer survivors living in the United States completed questionnaires measuring self-stigma, depressive symptoms, AEE, and intrusive thoughts. We found significant AEE × self-stigma and intrusive-thought × self-stigma interaction effects in predicting depressive symptoms. Specifically, the relationships between self-stigma and depressive symptoms were exacerbated among individuals with high levels of AEE and intrusive thoughts. Self-stigma represents a significant predictor of depressive symptoms among Chinese breast cancer survivors, and particularly so for individuals with higher levels of AEE and intrusive thoughts. The findings suggest that for interventions designed to reduce the negative mental health outcomes associated with self-stigma, targeting risk factors such as AEE and intrusive thoughts might be promising.

Objective: Recent research has documented the harmful effects of ambivalence over emotional expression (AEE) on psychological well-being, but few studies to date have examined AEE among Mainland Chinese breast cancer patients, an ethnic group that prioritizes emotion restraint to preserve social harmony. The present study examined the relationship between AEE and well-being (viz, anxious and depressive symptoms and quality of life) and evaluated perceived social support as a potential mediator of this relationship in a sample of Mainland Chinese breast cancer patients.Methods: Three hundred twenty-seven Chinese breast cancer patients recruited from Weifang, China, completed a self-reported questionnaire containing the Ambivalence over Emotional Expression Questionnaire (AEQ), the Medical Outcomes Study Social Support Scale (MOS-SSS), the Self-rating Anxiety Scale (SAS), the Self-rating Depression Scale (SDS), and the Functional Assessment of Cancer Therapy-Breast (FACT-B).Results: Overall, Mainland Chinese breast cancer patients endorsed high levels of AEE. A series of mediation analyses revealed perceived social support served as a partial mediator of the relationship between AEE and well-being. Specifically, AEE was associated with lower perceived social support (βs = -.13, P < .001), which in turn, was associated with greater anxious symptoms (β = .23, P < .001), depressive symptoms (β = .20, P < .001) and lower quality of life (β = -.30, P < .001).Conclusions: The harmful relationship between AEE and well-being is partially explained by reduced social support. Psychosocial interventions that facilitate emotional disclosure without harming social harmony may be culturally effective for mainland Chinese breast cancer patients. [ABSTRACT FROM AUTHOR]

There is increasing acknowledgement of social relationship as an important determinant of health. However, most evidence comes from developed countries, and the question of whether social relationship can predict health in developing countries remains poorly understood. This paper empirically examined how social relationships influence health in China. Data was collected from the Chinese Household Income Project, contained around 5000 migrant households, 8000 rural households and 5000 urban households. Self-reported general health and psychological health which was assessed by General Health Questionnaire. Social relationship was positively associated with health and psychological health, although the indices varied in strength. Social support, social connectedness and trust operated differently in predicting health in the three populations. The findings supported that social relationship influences health through both a stress-buffering process (helping people to cope with stress) and a main-effect process (promoting positive psychological states or healthy behaviors irrespective of stress). Among all the measures, neighborhood relationship satisfaction as one variable to capture social connectedness and generalized trust showed a stable and sizable effect in predicting health across the three populations, suggesting that neighborhood ties and generalized trust are important supportive resources for Chinese.

Individuals’ attitudes toward evidence-based practices (EBP) are critical in adopting, implementing and maintaining the EBP in clinical settings. Multiple empirical studies have examined how work context may shape perceptions and attitudes towards EBP. The current study aims to further explore how both work and family contexts, as assessed by three psychosocial indicators (i.e., occupational stress, work-related social support from coworkers, and work-related social support from family), may affect attitudes toward EBP among health care providers in HIV clinics in China. We analyzed cross-sectional survey data from 357 health care providers recruited from 40 HIV clinics across 16 cities/counties in Guangxi China. Structural equation model (SEM) was constructed to test the hypothesized relationships among key study variables. Occupational stress was negatively associated with work-related social support from coworkers (β = -.19, 95%CI = [-.31,-.12]), which in turn was positively associated with attitudes toward EBP (β = .17, 95%CI = [.04, .30]). Similarly, occupational stress was negatively related to work-related social support from family (β = -.34, 95%CI = [-.42,-.25]), which in turn was positively related to attitudes toward EBP (β = .23, 95%CI = [.12, .35]). Occupational stress was negatively associated with attitudes toward EBP, but the magnitude of association did not reach statistical significance at α = .05. Work-related social support from family partially mediated the association between occupational stress and attitudes toward EBP (Sobel’s z = 3.27, p < .05). Our findings suggest the importance of integrating work and family contexts, especially family support into the strategies of facilitating the adoption and implementation of EBP. The current study also underscores the needs to reduce occupational stress and enhance work-related social support among health care providers who are in frequent contact with HIV patients. In addition, lack of work-related family support may be a main barrier preventing health care providers from developing a positive attitude toward EBP. Therefore, the interventions aiming for promoting adoption and utilization of EBP need to involve specific strategies to resolve work-family conflicts and improve family members’ understanding and support for health care providers in China, especially those who work in a stressful work context such as HIV care.

The management of coalbed methane (CBM) co-produced waters (hereafter refer to as produced water) has broad effects on the native plants and soils in the Qinshui Basin of China and has become a high priority over the past decade. To investigate the short-term effects of produced water on crop production and soil health, a field study was conducted in the Shizhuang Block, which is one of the most active CBM-producing areas in the Qinshui Basin. Spring maize was grown during 2015 under the following flood irrigation treatments: freshwater (as a control), and three produced water sub-treatments with electrical conductivity (EC) values of 1.9 ± 0.9, 2.3 ± 0.5, and 3.4 ± 1.1 ds/m. The SAR concentration of the produced water ranged from 17.62 to 44.45 meq/L; the excessive SAR content makes the water unsuitable for direct irrigation without amendment. The pH, SAR, and constituent concentration of soil samples and crop yield were tested before planting and after harvest, while the soil moisture and plant height were measured monthly from June to October. The growth parameters indicated that salinity decreased total crop yield and individual plant height. The monitored soil indexes showed that the SAR content at a depth of 20 cm (top soil) exceeded that at 40 cm, and increased as the EC of the irrigation source increased at both depths. However, there were no obvious differences in pH or chemical composition of the soil samples, all being less than the Republic of China’s soil pollution standards. Soil moisture was determined more by the monsoon climate than by changes in the soils’ hydraulic properties. [ABSTRACT FROM AUTHOR]

Background: Meaning in life has been depicted as an important psychological resource for both children and adults.Objective: The specific aims of this study were to quantify the rates and severity of suicidal ideation in a sample of 6165 Chinese children and adolescent students from a wide range of areas across China and to investigate whether mental health status and meaning in life would be the predictors for suicidal ideation. More importantly, meaning in life was investigated as a possible moderator and a mediator of the influence of mental health status on suicidal ideation.Methods: Descriptive statistical analyses, Pearson correlation analyses, and hierarchical regression analyses were adopted as methods of data analyses.Results: Approximately 33.71% of students reported having suicidal ideation. Both mental health status and meaning in life were strong predictors of suicidal ideation. Results indicated that poorer mental health status was significantly associated with more severe suicidal ideation, whereas a weaker sense of meaning in life was significantly correlated with greater suicidal ideation. Mediation analysis showed that meaning in life partially mediated the link between mental health status and the severity of suicidal ideation. Specifically, students who experienced poorer mental health status might be more likely to report having a weaker sense of meaning in life, which in turn promotes greater suicidal ideation. Moderation analysis showed that the impact of mental health status on suicidal ideation was significantly greater among children and adolescents with a weaker sense of meaning in life.Conclusions: Results are discussed with regard to the potential value of meaning in life and mental health status in building predictive models of suicidal ideation.

In this study, we investigated the relationship between work–family conflict and job burnout as well as the potential mediation/moderation effects of psychological capital. Participants were 357 university teachers who completed a questionnaire packet containing a work–family conflict scale, psychological capital questionnaire, and Maslach Burnout Inventory–General survey. According to the results, work–family conflict and psychological capital were both significantly correlated with job burnout. In addition, psychological capital cannot mediate—but can moderate—the relationship between work–family conflict and job burnout. Taken together, our findings shed light on the psychological capital underlying the association of work–family conflict and job burnout. [ABSTRACT FROM AUTHOR]

Background: Poor sleep quality and depression negatively impact the health-related quality of life of patients with type 2 diabetes, but the combined effect of the two factors is unknown. This study aimed to assess the interactive effects of poor sleep quality and depression on the quality of life in patients with type 2 diabetes. Methods: Patients with type 2 diabetes (n = 944) completed the Diabetes Specificity Quality of Life scale (DSQL) and questionnaires on sleep quality and depression. The products of poor sleep quality and depression were added to the logistic regression model to evaluate their multiplicative interactions, which were expressed as the relative excess risk of interaction (RERI), the attributable proportion (AP) of interaction, and the synergy index (S). Results: Poor sleep quality and depressive symptoms both increased DSQL scores. The co-presence of poor sleep quality and depressive symptoms significantly reduced DSQL scores by a factor of 3.96 on biological interaction measures. The relative excess risk of interaction was 1.08. The combined effect of poor sleep quality and depressive symptoms was observed only in women. Conclusions: Patients with both depressive symptoms and poor sleep quality are at an increased risk of reduction in diabetes-related quality of life, and this risk is particularly high for women due to the interaction effect. Clinicians should screen for and treat sleep difficulties and depressive symptoms in patients with type 2 diabetes. [ABSTRACT FROM AUTHOR]

Background: Post-traumatic stress disorder (PTSD) is a disorder that can affect people following the experience of a traumatic event. Few studies have researched on PTSD symptoms of patients with central nervous system tumors. In this study, we aim to examine the association between social support and PTSD symptoms and to explore the mediating effect of self-efficacy in this relationship among patients with central nervous system tumors in China. Methods: Questionnaires consisting of the Post-traumatic Stress Checklist-Civilian Version, the Duke-UNC Functional Social Support Questionnaire, the General Self-Efficacy Scale, as well as demographic and clinical factors were used to collect information of patients with central nervous system tumors in Liaoning Province, China. A total of 222 patients (effective response rate of 66.1%) became our subjects. Hierarchical linear regression analyses were performed to explore the association between social support and PTSD symptoms and the mediating effect of self-efficacy. Results: After adjusting for demographic characteristics and tumor type, social support was negatively associated with the total score of PTSD symptoms (β = -0.342, P < 0.01). Social support explained 8.8% of the variance in PTSD symptoms. Self-efficacy was found to partially mediate the relationship between social support and PTSD symptoms. Conclusions: Self-efficacy partially mediated the relationship between social support and PTSD symptoms. Interventions focusing on both social support and self-efficacy might be more useful than interventions only targeting either of them. [ABSTRACT FROM AUTHOR]

Background: The current literature on the influences of family environment on childhood obesity is predominantly based on western populations and has focused on the role of parents. This study examined the influence of grandparents on the development of obesity among Chinese primary school aged children. Methods: A mixed methods study was conducted in four socioeconomically distinct primary school communities in two cities of southern China. The qualitative study (17 focus groups and four personal interviews) involved parents, grandparents, school staff, and food retailers in the vicinity of the schools (n = 99) and explored perceived causes of childhood obesity. The cross-sectional study examined the association between children's objectively measured weight status and reported health behaviours, and the presence and role of grandparents in the household. It included children from three randomly selected third grade (8 to 10 years) classes from each school (n = 497). Results: Grandparents were commonly perceived to contribute to childhood obesity through inappropriate perception (e.g. fat children are healthy and well cared for), knowledge (e.g. obesity related diseases can only happen in adults; the higher the dietary energy/fat content, the more nutritious the food), and behaviour (e.g. overfeeding and indulging through excusing the children from household chores). Conflicting child care beliefs and practices between grandparents and parents, and between grandparents and school teachers, were felt to undermine efforts to promote healthy behaviours in children. In the cross-sectional study, children who were mainly cared for by their grandparents were more likely to be overweight/obese (adjusted OR = 2.03; 95 % CI = 1.19 to 3.47); and to consume more sugar-added drinks and unhealthy snacks (B = 2.13, 95 % CI = 0.87 to 3.40), than children who were mainly cared for by their parents or other adult. Children who lived with two or more grandparents in the household were more likely to be overweight/obese than children who did not live with any grandparent (adjusted OR = 1.72; 95 % CI = 1.00 to 2.94). Conclusions: Involvement of grandparents in childcare is an important factor contributing to childhood obesity in China. Future preventive interventions should include strategies that target grandparents. [ABSTRACT FROM AUTHOR]

Background: Intelligent healthcare (IH) is proposed with the fast application of Internet of Things technology in the healthcare area in recent years. It is considered as an expansion of e-health and telemedicine. As the largest developing country, China is investing large amounts of resources to push forward the development of IH. It is one of the centerpieces of the country's New Healthcare Reform, and great expectation is placed on it to help solve the conflict between limited healthcare resources and the large patient population. Materials and Methods: Essential policies, milestones, standards, and specifications from the Chinese government since the 1990s were reviewed to show the brief development history of IH in China. Some typical cases and products have been analyzed to present the current situation. The main problems and future development directions have been summarized. Conclusions: The IH industry in China has great potential and is growing very fast, but a lot of challenges also exist. In the future both government support and the active participation of nongovernmental capital are needed to push forward the whole industry. [ABSTRACT FROM AUTHOR]

Worldwide promotion of infant formula and other commercial baby foods is leading to increased use of these products, raising concerns about their impact on the health of infants. These products are made and marketed through a global system that extends beyond the control of separate nations. As the industry is increasingly globalized, there is a growing need for guidance, monitoring, and regulation. This study suggests a path toward achieving better control of infant formula and other baby foods to ensure that infants and young children everywhere are well nourished. The negotiation of a new Optional Protocol on Children's Nutrition, to be linked to the most relevant human rights treaty, the Convention on the Rights of the Child, would bring the major issues relating to infant formula and other baby foods to the attention of the global community and all national governments.

As one of the unconventional natural gas family members, coalbed methane (CBM) receives great attention throughout the world. The major associated problem of CBM production is the management of produced water. In the USA, Canada, and Australia, much research has been done on the effects and management of coalbed methane produced water (CMPW). However, in China, the environmental effects of CMPW were overlooked. The quantity and the quality of CMPW both vary enormously between coal basins or stratigraphic units in China. The unit produced water volume of CBM wells in China ranges from 10 to 271,280 L/well/day, and the concentration of total dissolved solids (TDS) ranges from 691 to 93,898 mg/L. Most pH values of CMPW are more than 7.0, showing the alkaline feature, and the Na-HCO and Na-HCO-Cl are typical types of CMPW in China. Treatment and utilization of CMPW in China lag far behind the USA and Australia, and CMPW is mainly managed by surface impoundments and evaporation. Currently, the core environmental issues associated with CMPW in China are that the potential environmental problems of CMPW have not been given enough attention, and relevant regulations as well as environmental impact assessment (EIA) guidelines for CMPW are still lacking. Other potential issues in China includes (1) water quality monitoring issues for CMPW with special components in special areas, (2) groundwater level decline issues associated with the dewatering process, and (3) potential environmental issues of groundwater pollution associated with hydraulic fracturing.

Objective: We sought to compare the efficacy of the '512 Psychological Intervention Model' (that is, '512 PIM', a new psychological intervention) with debriefing on symptoms of post-traumatic stress disorder (PTSD), anxiety and depression of Chinese military rescuers in relation to a control group that had no intervention. Method: We conducted a randomized controlled trial with 2,368 military rescuers 1 month after this event and then at follow-up 1, 2 and 4 months later to evaluate changes in symptoms of PTSD, anxiety and depression based on DSM-IV criteria, respectively. Results: Baseline analysis suggested no significant differences between the study groups. Severity of PTSD, anxiety and depression decreased over time in all three groups, with significant differences between the groups in symptoms of PTSD ( P < 0.01). Compared with the debriefing and control group, significant lower scores of PTSD and positive efficacy in improving symptoms of re-experiencing, avoidance and hyperarousal were found in the '512 PIM' group. Conclusion: '512 PIM' was an effective psychological intervention for military rescuers in reducing symptoms of PTSD, anxiety and depression after a crisis. [ABSTRACT FROM AUTHOR]

im: Resilience refers to positive adaption in the face of stress or trauma. Assessing resilience is crucial in trauma-related research and practice. The 10-item Connor-Davidson Resilience Scale (CD-RISC) has been demonstrated to be a valid and reliable tool to achieve this goal. This study was designed to examine the psychometric properties of the 10-item CD-RISC in a sample of Chinese earthquake victims. Methods: A total of 341 participants (185 women, 156 men) aged 20-63 years were recruited from a psychological relief program supported by the Institute of Psychology, Chinese Academy of Sciences following the 'Wenchuan' earthquake. The participants were given the 10-item CD-RISC and the 17-item post-traumatic stress disorder (PTSD) subscale of the Los Angeles Symptom Checklist (LASC) 4 months after the earthquake. Results: The results of exploratory factor analysis indicated that a single-factor model consistent with the original design of the 10-item CD-RISC was support. The scale was also demonstrated to have good internal consistency (Cronbach's alpha = 0.91) and test-retest reliability ( r = 0.90 for a two-week interval). Scores on the scale could reflect different levels of resilience in populations that are thought to be differentiated (probable PTSD vs healthy controls, t(339) = −7.60, P < 0.01, Cohen's d = 0.84). Moreover, the total resilience scores were significantly negatively correlated with scores on total PTSD scale and its three subscales for all participants. Conclusion: The Chinese version of the 10-item CD-RISC has excellent psychometric properties, and is applicable for Chinese people. [ABSTRACT FROM AUTHOR]

Prior literature on foreign direct investment (FDI) spillovers has mainly focused on how the presence of FDI affects the productivity of domestic firms. In this study, we advance the literature by examining the effect of the diversity of FDI country origins on the productivity of domestic firms. We propose that the diversity of FDI country origins can facilitate FDI spillovers by increasing the variety of technologies and management practices brought by foreign firms, to which domestic firms are exposed and that they can potentially utilize. Further, the extent to which domestic firms can utilize these technologies and practices depends upon their absorptive capacity. Using panel data on Chinese manufacturing firms during the period 1998–2003, our results support these propositions. We find that the diversity of FDI country origins in an industry has a positive relationship with the productivity of domestic firms in the industry. This positive relationship is stronger when domestic firms are larger, and when the technology gap between FDI and the domestic firms is intermediate. Copyright © 2010 John Wiley & Sons, Ltd.

We introduce a new pragmatic procedure called the ‘climate learning ladder’ to structure policy analysis, support reflection and identify critical decisions to support climate adaptation. This tool is the result of the reflexive learning process that occurred while developing innovative appraisal methods in the Alxa League of Inner Mongolia, China, and in the Guadiana river basin in the European Union. Building capacities to cope with climate change requires going beyond simply providing ‘more knowledge’ on climate impacts to policy makers. Instead, climate adaptation can be understood as a multi-step social process in which individuals and organizations need to learn how to (1) manage different framings of the issues at stake while raising awareness of climate risks and opportunities, (2) understand different motives for, and generate adequate incentives or sanctions to ensure, action, (3) develop feasible options and resources for individual and collective transformation and collaboration and (4) institutionalize new rights, responsibilities and feedback learning processes for climate adaptation in the long term.

Background This is an exploratory study on the psychometric properties and normative data of the Chinese translation of the Impact of Event Scale — Revised (CIES-R). Methods The original Impact of Event Scale — Revised was translated into Chinese and the comparability of content was verified through backtranslation procedures. The study consisted of a sample of 116 patients from the Accident and Emergency Department. Results The reliability of the Chinese version was verified. The validity of the Chinese version as a measure of psychological distress was supported by the positive correlations between the various subscale scores of CIES-R (i. e., Intrusion, Avoidance, and Hyperarousal) and General Health Questionnaire-20. However, the independence of the three subscales was not supported. Conclusions The present result suggests that normative information for different age groups and clinical samples might be different. Further study with clinical sample and investigation of the relationship between CIES-R and other diagnostic measures of PTSD are discussed. [ABSTRACT FROM AUTHOR]

Background: Shiga toxin-producing Escherichia coli (STEC) is a leading cause of worldwide food-borne and waterborne infections. Despite an increase in the number of STEC outbreaks, there is a lack of data on prevalence of STEC at the farm level, distribution of serogroups, and virulence factors. Results: In the present study, a total of 91 (6.16%) STEC strains were isolated from 1477 samples including pig intestines, pig feces, cattle feces, milk, and water from dairy farms. The isolation rates of STEC strains from pig intestines, pig feces, and cattle feces were 7.41% (32/432), 4.38% (21/480), and 9.57% (38/397), respectively. No STEC was isolated from the fresh milk and water samples. By O-serotyping methods, a total of 30 types of O-antigens were determined, and the main types were O100, O97, O91, O149, O26, O92, O102, O157, and O34. Detection of selected virulence genes (stx1, stx2, eae, ehxA, saa) revealed that over 94.51% (86/91) of the isolates carried more than two types of virulence associated genes, and approximately 71.43% (65/91) of the isolates carried both stx1 and stx2, simultaneously. Antimicrobial susceptibility tests showed that most of the STEC isolates were susceptible to ofloxacin and norfloxacin, but showed resistance to tetracycline, kanamycin, trimethoprim-sulfamethoxazole, streptomycin, amoxicillin, and ampicillin. MLST determined 13 categories of sequence types (STs), and ST297 (31.87%; 29/91) was the most dominant clone. This clone displayed a close relationship to virulent strains STEC ST678 (O104: H4). The prevalence of ST297 clones should receive more attentions. Conclusions: Our preliminary data revealed that a heterogeneous group of STEC is present, but the non-O157 serogroups and some ST clones such as ST297 should receive more attentions.

Background: Studies investigating the prevalence of positive mental health and its correlates are still scarce compared to the studies on mental disorders, although there is growing interest of assessing positive mental health in adolescents. So far, no other study examining the prevalence and determinants of positive mental health in Chinese adolescents has been found. The purpose of this study was to assess the prevalence and correlates of positive mental health in Chinese adolescents.Methods: This cross-sectional study used a questionnaire including Mental Health Continuum-Short Form (MHC-SF) and items regarding multiple aspects of adolescent life. The sample involved a total of 5399 students from grade 8 and 10 in Weifang, China. Multivariate Logistic regression analyses were performed to evaluate the associations between potential indicators regarding socio-economic situations, life style, social support and school life and positive mental health and calculate odds ratios and 95% confidence intervals.Results: More than half (57.4%) of the participants were diagnosed as flourishing. The correlated factors of positive mental health in regression models included gender, perceived family economy, the occurrence of sibling(s), satisfaction of self-appearance, physical activity, sleep quality, stress, social trust, desire to learn, support from teachers and parents as well as whether being bullied at school (OR ranging from 1.23 to 2.75). The Hosmer-Lemeshow p-value for the final regression model (0.45) indicated adequate model fit.Conclusion: This study gives the first overview on prevalence and correlates of positive mental health in Chinese adolescents. The prevalence of positive mental health in Chinese adolescents is higher than reported in most of the previous studies also using MHC-SF. Our findings suggest that adolescents with advantageous socio-economic situations, life style, social support and school life are experiencing better positive mental health than others.
