关键词： Psychosocial factors;NSSI deliberate self-harm;adolescents with mood disorders;self-esteem;family support

摘要： Background: According to the integrated theoretical model, adolescents' behaviors were the outcome of the complex interplay between multiple levels. Non-suicidal self-injury (NSSI) is a serious and high prevalent problem among adolescents with mood disorders. However, a systematic perspective on psychosocial correlates among Chinese clinical adolescents is still rare. Method: The impact of several factors at the individual (i.e., sex, age, self-esteem, and psychological distress), family (i.e., family structure, family income, and family support), and social level (i.e., living environment, peer support, and teacher support) on the frequency of NSSI behaviors were investigated in the current study. This research included 621 Chinese adolescents with mood disorders from 20 hospitals. Results: Three-steps hierarchical regression analyses indicated that lower levels of psychological distress and higher levels of self-esteem were most associated with less frequency of NSSI behaviors. In addition, family support was negatively associated with the frequency of NSSI behaviors. After controlling the factors at individual and family levels, no significant association was found between the factors at the social level and the frequency of NSSI behaviors. Conclusion: These findings provide preliminary support for the notion that adolescent self-esteem and family support may effectively shield them from problematic behavior; nevertheless, adolescents suffering from more emotional pain can be even riskier. Thus, further intervention strategies should consider the non-independence of individual capacities, co-combinatory effects of mood disorder, and family environment in treating those vulnerable Chinese adolescents.

关键词： cultivated land;carbon emissions;spatiotemporal characteristics;driving factor;decoupling effect;LMDI model

摘要： The carbon emission level and spatiotemporal characteristics in Hubei Province were estimated and studied using the Intergovernmental Panel on Climate Change (IPCC) carbon emission coefficient technique based on county data from Hubei Province from 2000 to 2020. The relationship between carbon emissions from cultivated land utilization and agricultural economic growth was examined using the Tapio decoupling index, and the factors influencing carbon emissions in Hubei Province were further examined using the Logarithmic Mean Divisia Index (LMDI model). The results demonstrate that: (1) Spatiotemporal variations in carbon emissions are evident. In terms of time, the volume of carbon emissions in Hubei Province is still substantial, and the transition to low-carbon land use is quite gradual. Geographically, the high-value region of the middle east coexists with the low-value zone of the west, with apparent regional contrasts. (2) The decoupling between carbon emissions and agricultural economic growth is becoming more and more obvious in Hubei Province. The number of counties and cities in a negative decoupling state has significantly decreased, and the majority of counties are now in a strong decoupling condition. (3) Agricultural production efficiency is the most significant driving factor for restricting carbon emission, according to the decomposition results of carbon emission driving factors based on the LMDI model. In addition, the results of sample decomposition based on topographic characteristics indicate that agricultural production efficiency is primarily responsible for the suppression of carbon emissions in flat regions. The increase in carbon emissions in hilly regions is primarily influenced by agricultural productivity. The increase in carbon emissions in mountainous regions is mostly influenced by agricultural labor intensity. This study′s finding has enlightening implications for the high-quality growth of agriculture. © 2022 by the authors.

关键词： rural collective construction land (RCCL);asset specificity;transaction uncertainty;transaction costs;transaction rules

摘要： In China, rural construction land refers to the construction land of townships (town) and villages. The construction land of townships (town) and villages refers to the land used by township (town) and village collective economic organizations and rural individuals to invest or raise funds for various non-agricultural construction. Rural collective construction land is divided into three categories: homestead, land for public welfare public facilities, and land for business. Complete market transaction rules can make the market of rural collective construction land run more openly, fairly, and justly, thus protecting the rights of villagers and collective economic organizations and, at the same time, reducing the transaction cost of the village collective. In this paper, we choose the formal rules of the urban and rural land linking quota trading market in Ezhou, Hubei Province, China, to analyze the three dimensions of the market transaction rules and villagers’ willingness. We also provide suggestions for the development of the RCCL market and the improvement of trading rules. The research results of the logistic model show the following: (1) Under the arrangement of the transaction rules of the RCCL, there are high transaction costs, especially labor costs and time costs, so the villagers’ willingness to enter the market is not very strong. (2) Asset specificity affects villagers’ willingness. The larger the area of RCCL involved in the transaction, the higher the transaction cost, the lower the villagers’ willingness to support the RCCL transfer. (3) The greater the uncertainty of the RCCL transaction environment—mainly due to the problems of the openness, equity, and justice of the transaction rules, which lies in the transaction information not being transparent and the income distribution and the pricing being unreasonable, resulting in villagers’ rights being denied—the more the villagers are unwilling to support the RCCL entering the market. Therefore, we suggest that more open, fair, and just trading rules of the RCCL market should be formulated to protect the security of villagers’ property rights. Moreover, the land value should be displayed reasonably, which can also standardize the good trading order and trading environment, thus making the market development more effective and stable. Our work provides some insights for improving the efficiency of the land market, which will contribute to the development of the worldwide RCCL market. © 2022 by the authors.

关键词： tourism eco-efficiency;tourism economy;interactive response mechanism;China;sub-provinces

摘要： Although the development of tourism has a positive impact on local employment and economic growth, the high level of energy consumption and emissions generated by tourism have also attracted increasing attention. Based on the concept of tourism eco-efficiency, this article constructs a comprehensive evaluation system for tourism eco-efficiency in China, and the study concludes that (1) China's tourism eco-efficiency as a whole was in a fluctuating upward trend from 2002 to 2018, but different provinces of tourism eco-efficiency varied greatly, and the range of tourism eco-efficiency on spatial spill-over increased significantly; (2) the impact of tourism economic development on tourism eco-efficiency was not significant over time, and the impact of tourism eco-efficiency on the sustainable development of the tourism economy in the western region was weaker; (3) the contribution of tourism economic development to tourism eco-efficiency was low at the national level, with regional levels ranging from large to small for the western region, the central region, and the eastern region. The contribution of tourism eco-efficiency to the tourism economy was also low at the national level, with the central, eastern, and western regions ranked in descending order at the regional level.

关键词： silver nanoparticles;aggregation;dissolution;sludge;high ammonia nitrogen wastewater

摘要： Silver nanoparticles (AgNPs) are released into the sewage pipes and ultimately wastewater treatment plants during manufacturing, use, and end–life disposal. AgNPs in wastewater treatment plants aggregate or dissolve, and may affect the microbial community and subsequent pollutant removal efficiency. This study aims to quantitatively investigate the fate of AgNPs in synthetic high ammonia nitrogen wastewater (SW) and sludge from an up–flow anaerobic sludge blanket (UASB) anammox reactor using a nanoparticle tracking analysis (NTA), dynamic light scattering (DLS), transmission electron microscope (TEM), and atomic absorption spectroscopy (AAS). Results showed that 18.1 mM NH4+, 2.11 mM Mg2+ in SW caused less negative zeta potential (ζ−potential, −18.4 vs. −37.4 mV), aggregation (388.8 vs. 21.5 nm), and settlement (80%) of citrate−coated AgNPs (cit−AgNPs) in 220 min. The presence of 18.5 mM Cl− in SW formed AgCl2−, AgCl(aq) and eventually promoted the dissolution (9.3%) of cit−AgNPs. Further exposure of SW−diluted AgNPs to sludge (42 mg L−1 humic acid) and induced a more negative ζ−potential (−22.2 vs. −18.4 mV) and smaller aggregates (313.4 vs. 388.8 nm) due to the steric and hindrance effect. The promoted Ag dissolution (34.4% vs. 9.3%) was also observed after the addition of sludge and the possible reason may be the production of Ag(NH3)2+ by the coexistence of HA from sludge and NH4+ from SW. These findings on the fate of AgNPs can be used to explain why AgNPs had limited effects on the sludge−retained bacteria which are responsible for the anammox process. © 2022 by the authors.

关键词： agricultural futures;time-varying value-at-risk;wavelet approaches

摘要： Abstract This paper measures pairwise multiscale extreme risk interdependence between the five major agricultural futures. This topic has economic importance for agricultural market participants because potentially high losses might occur due to the cross‐market extreme risk transmissions. Downside risk is observed via time‐varying Value‐at‐Risk time‐series, while the multiscale analysis is conducted using several wavelet approaches. Results of wavelet coherence show an absence of high interdependence in the short‐term horizons, while at higher wavelet scales, we find stronger connection only in some cases—corn–wheat, corn–soybean, wheat–soybean and somewhat corn–rice. High coherence islands are detected around the global financial crisis, but only in a few cases, which means that commodity financialization could play an important role when it comes to extreme risk. Wavelet correlations and wavelet‐based quantile regression support the wavelet coherence findings in great deal, adding to the robustness of the overall results. Phase difference indicates that bigger markets, such as corn, wheat, and soybean, mostly lead two smaller markets—rice and oats in the midterm and long‐term horizons, but a consistent and long‐lasting pattern is evident only between corn and soybean. An absence of a clear‐cut downside interdependence means that agricultural agents do not need to worry too much about the damaging extreme risk spillover effects from other neighboring agricultural markets.

关键词： teacher's emotional display;students' perceptions;students' productivity;online learning;small-group discussion

摘要： Teacher's emotions have been shown to be highly important in the quality and effectiveness of teaching and learning. There is a recognized need to examine the essential role of teacher's emotions in students' academic achievement. However, the influence of teacher's displays of emotions on students' outcomes in small-group interaction activities, especially in the online environment, has received little attention in prior research. The aim of the present study was to explore the relationship between teacher's different emotional displays and students' perceptions of the teacher's competence, as well as students' collaborative feelings and productivity in online small-group discussions. Using a three-level between-subjects design, 74 participants were randomly divided into four-member groups comprising a teacher and three other participants. All the groups were asked to discuss an open-ended realistic problem using online software, during which the teacher's display of emotions varied (positive vs. negative vs. neutral). The participants' self-reported questionnaire data (perception of the teacher's competence, students' feeling of pleasure, collaborative satisfaction, and willingness to continue collaborating) and productivity (number of effective ideas expressed within a given time) were measured to compare the participants who were exposed to different emotional displays. As expected, the results showed that the participants who received the teacher's positive emotional display reported that they experienced higher levels of pleasure during the task. However, in contrast to our expectations, those under the negative emotional display condition showed a significantly higher level of productivity in the group task. In addition, compared to emotional display, the participants' perceptions of the teacher's competence were rated significantly higher under the neutral condition, and they reported higher levels of collaborative satisfaction and greater willingness to continue collaborating with their group. The findings have the potential benefit of informing educational practice on whether teachers should display their emotions in a small-group discussion or how they should display emotions following adjustment for the relative aim of the teaching activities.

摘要： Since the 1980s, the research of artificial neural networks in the field of artificial intelligence has become more and more common. It accepts nonlinear parallel processing, has strong learning and flexibility, and can be used for influencing factor analysis. The ideal power values and triggers are obtained in the Hopfield network model using genetic algorithm, which best avoids the drawbacks of the Hopfield network model instillation learning method. Through the BP of mobile human-computer interaction equipment, hereditary, genetic algorithms, and Hi-PLS regression method in the artificial neural network, the psychological pressure of college students is identified, evaluated, and predicted from three dimensions such as learning, life, and personal events. This makes it possible to understand the current physical and mental conditions of the students in a timely manner, guide to relieve anxiety and fear, and reach a safe psychological level. The three test results are less than 1%, which has high research significance and value. © 2022 Na Zhang.

关键词： cohorts;Hong Kong;housing and land policies;housing tenure;residential mobility

摘要： Hong Kong has experienced rounds of property bubble inflation and burst, underscoring heightened market volatility amidst the financialization of the world economy. Irrespective of its fame as an exemplar of laissez faire capitalism, the city's massive public housing programme consisting of public rental housing (PRH) and the Homeownership Scheme (HOS) places the Hong Kong government among the world's biggest landlords and developers. It is within such varying and heavily manipulated choice sets that residential decisions in Hong Kong are exercised. Employing the past five population censuses (by-censuses), this paper studies the city's changing scenes of residential mobility over the period 1991–2016, juxtaposing against changes in housing and land policies and the broader socioeconomic environment. The results reveal relatively frequent moves in the 1990s, but drastic and consistent declines in the mobility rates thereafter, especially for HOS and PRH residents. Private renters, however, stayed mobile throughout the 25-year period. Such variations in trend point towards the recent dismantling of the housing ladder with PRH and HOS being major steps in the transition from private renting to owner-occupation. Particularly affected are the younger generations. Expectedly, recent immigrants from mainland China fare less well in the housing realm. Nevertheless, with the attainment of the permanent resident status in Hong Kong, mainlanders and local born increasingly exhibit similar patterns of residential movements. © 2022 John Wiley & Sons Ltd.

摘要： The application of digital technology in teaching has triggered the evolution of traditional teaching. Students have different corresponding relationships under digital behavior. The interactive technology of artificial intelligence (AI) and virtual reality (VR) provides a new driving force for the development of art education and psychology. Firstly, this thesis analyzes the limitations and existing problems of traditional art education. Especially, the influence of the teaching mode of art education on the teaching of other disciplines develops a targeted student-centered digital education program. Secondly, the author used VR equipment and technology to let students experience the virtual world freely, and then, the relevant data model was established on the basis of analyzing the reasons affecting students’ creativity and concentration. Thirdly, the data model was applied to art education in order to improve students’ concentration and creativity. Then, the author compared and analyzed the data of the students under different teaching models through questionnaires. The results show that introducing VR and AI technology into art education and encouraging students to carry out deep learning can significantly improve student concentration and creativity. Finally, the influence reasons are analyzed from the perspective of psychology. VR interaction and Artificial Intelligence can be introduced into middle school fine art education which is to the benefit of students’ deep learning, thus students’ concentration and creativity can be improved.

关键词： tourism supply chain;supply chain vulnerability;supply chain resilience;uncertain environment;tourism sustainability

摘要： The uncertainty environment brought about by COVID-19 has broken the original stable hierarchical network structure and the whole supply and demand system of the tourism supply chain (TSC), which has brought heavy losses to the tourism industry. Using the case research and consensual qualitative research (CQR) method, taking the real situation and perception of individual supply chain members as a window, supplemented by the narrative insertion of Lijiang Yulong Tourism Co., Ltd., Lijiang Old Town and Yulong Snow Mountain scenic areas, the general laws of the vulnerability and resilience of the TSC were glimpsed. The results show that there are vulnerability factors in the TSC including the supply side, demand side, government side, destination economic structure and supply chain attributes, which lead to the interruption and damage of the TSC after the outbreak of the pandemic. At the same time, China’s overall economic environment, tourism demand side, supply side, government side and market participants all have resilience elements. Behind the vulnerability, there is a power of recovery and opportunities for innovation and change. The TSC shows a trend of restorative growth. Theoretically, it helps to enrich theories of TSC and supply chain management under an emergency crisis. In practice, the response behavior of participants at different levels of the supply chain is also the basis for TSC risk management and formulation of optimization strategies in the future, which helps tourism sustainable development in the uncertain environment. © 2022 by the authors.

关键词： Construction cost index;Construction investment management;Multivariate analysis;Prediction model

摘要： Construction costs and investment planning are the decisions made by construction managers and financial managers. Investment in construction materials, labor, and other miscellaneous should consider their huge costs. For these reasons, this research focused on analyzing construction costs from the point of adopting multivariate cost prediction models in predicting construction cost index (CCI) and other independent variables from September 2021 to December 2022. The United States was selected as the focal country for the study because of its size and influence. Specifically, we used the Statistical Package for Social Sciences (SPSS) software and R-programming applications to forecast the elected variables based on the literature review. These forecasted values were compared to the CCI using Pearson correlations to assess influencing factors. The results indicated that the ARIMA model is the best forecasting model since it has the highest model-fit correlation. Additionally, the number of building permits issued, the consumer price index, the amount of money supply in the country, the producer price index, and the import price index are the influencing factors of investments decisions in short to medium ranges. This result provides insights to managers and cost planners in determining the best model to adopt. The improved accuracies of the influencing factors will help to enhance the control, competitiveness, and capability of futuristic decision-making of the cost of materials and labor in the construction industry. © 2022 by the authors.

关键词： bank efficiency;corporate social responsibility;sustainable business perspectives;Industrial and Commercial Bank of China

摘要： The goal of the basic business perspective has switched from previously maximizing profit to the current three fields of environment, society, and the economy, within the viewpoint of corporate social responsibility (CSR). This study, from the perspective of sustainability, discusses the current business model of the relationship between CSR and the performance of the Industrial and Commercial Bank of China (ICBC), a state−owned bank, with SBM-DEA and Tobit regression methods, and it puts forward a direction for improvement for future business models. Through the analysis of the years from 2010 to 2018, it has been found that the years with the best performances are 2010, 2011, and 2018, and some empirical evidence from the ICBC is as follows. First, corporate financial leverage closely follows gross domestic product (GDP) growth in terms of utilizing total assets. The ICBC seems to place less attention on its sales and on the number of deposits because of its high ratio of government stock holdings. Second, the ICBC raises labor productivity through education and training of its employees as well as through the proper utilization of capital for input-side management. Lastly, performance has improved as the ICBC has focused more on long-term society contributions, which are directed toward charity donations, loans for poverty alleviation, and green economy development in terms of output-side management. Therefore, through the above three CSR strategies, the ICBC has positively contributed toward environmental innovation and the societal transition of China, and its practices can be used as a sustainable model for future development. © 2022 by the authors.

摘要： The development trend of tourism performance networking, although convenient for audience consumption, also makes the performance information present the development trend of big data. In the mass of information, how to accurately locate products and improve audience satisfaction is an urgent problem to be solved. In order to better explore the evaluation of tourism performance by the customer satisfaction evaluation model, analyze the development prospect of tourism in Jiangxi Province in the future, improve the customer satisfaction evaluation model with rough set, and propose a composite customer satisfaction evaluation model. By setting the adjustment value of the evaluation index, the model not only avoids the &#x201c;false eigenvalue&#x201d; of the satisfaction evaluation result but also simplifies the calculation process of the model and improves the accuracy, calculation efficiency, and single data processing capacity of the satisfaction evaluation. According to the MATLAB simulation results, the composite customer satisfaction evaluation model constructed in this study is better, the calculation accuracy is &#x3e;97&#x0025;, and the calculation time is 40 seconds, which are better than the original customer satisfaction evaluation model. Therefore, the composite customer satisfaction evaluation model can be applied to the evaluation of tourism performance products to provide data support for the evaluation price of audience satisfaction in Jiangxi Province.

摘要： The Surgical procedure of cesarean section ( CS) causes a large wound that any delay in its healing could increase the rate of stress, inconvenience, and dissatisfaction among the women who underwent CS procedure about six weeks after childbirth. The present study is trying to evaluate the effect of alginate and gelatin hydrogel composited with nanozinc effective extensibility and compressibility as a wound dressing nursing care after CS. The number of participants was 700 individuals enrolled all who underwent C-sections at Medical College in the Second Affiliated Hospital of Xi'an Jiaotong University (from September 2017 until September 2020). Patients were divided into two groups of case and control consist of 350 cases. The case group was treated with alginate gelatin hydrogel-nZnO + antibacterial wound dress and the control group was treated with wound healing ordinary creams + antibacterial. Three and four weeks following CS, the healing process of the wound was evaluated using REEDA wound scale. In the current study, there was not any significant difference between the studied case and control group in respect to individual's demographical characteristics such as economic status, educational level, BMI, and age. (P > 0.05). Also, we observed that patients treated with alginate gelatin hydrogel-nZnO would experience a significantly lower score for redness, ecchymosis, edema, and approximation of CS wound in comparison to the control group (P < 0.05). Also, slope analysis showed that the healing process was significantly quicker in patients treated with alginate gelatin hydrogel-nZnO in comparison to the control group. Finally, it was observed that more than 80% of patients did not represent any major sign of CS after three weeks, however, in the control case this issue was estimated at 50.6%. No allergic reaction has been observed. Our results showed that using alginate gelatin hydrogel-nZnO wound dress could be a novel treatment in a nursing care setting to decrease the CS wound complication and increase the healing process without any allergic reaction.

摘要： Based on work-family border theory and work-home resource theory (W-HR), this paper examines the impact of border keeper’s support (organizational support and family support) on work-family enrichment and whether or how work-family boundary flexibility mediates the relationship between border keeper’s support and work-family enrichment. A sample of 504 preschool teachers in Guangdong province, China completed questionnaires. The research results show a two-way process of work-family enrichment for preschool teachers in China. Organizational support was directly and significantly correlated with work-to-family enrichment (WFE), and family support was significantly and directly correlated with family-to-work enrichment (FWE). Organizational support had no significant positive predictive effect on work boundary flexibility which has a significant positive predictive effect on WFE. Family support had a significant positive predictive effect on family boundary flexibility which had a significant positive predictive effect on the FWE. In addition, the study found that family boundary flexibility mediates the relationships between family support and FWE whereas work boundary flexibility did not mediate the relationships between organizational support and WFE. The above research results are partly consistent with the existing research, and partly inconsistent, which is related to the profound influence of traditional culture in Chinese society and the current situation of preschool teachers in China. Such findings have important implications for improving the work-family enrichment of preschool teachers. Copyright © 2022 Peng, Lian and Zhang.

关键词： Chlorogenic acid;Optimal design;Preprocessing;Ultrasonic-assisted extraction;Waste treatment

摘要： Using tobacco waste as raw material, the ultrasonic-assisted extraction of chlorogenic acid was optimized by response surface methodology (RSM). After repeated freezing and thawing of tobacco waste twice, the effect of pH value, ethanol volume fraction, temperature and extraction time on the extraction rate of chlorogenic acid was investigated by a single factor experiment. On the basis of this, the factors affecting the yield of chlorogenic acid were further optimized by using RSM. The optimum extraction conditions for chlorogenic acid were set at pH = 4.1, ethanol volume fraction was 49.57% and extraction time was 2.06 h. Under the above conditions, the extraction rate of chlorogenic acid could reach 0.502%, which was higher than traditional extraction and unpretreated ultrasonic extraction. All these results can be used as a reference for the extraction of effective ingredients in tobacco waste. © 2022 by the authors. Licensee MDPI, Basel, Switzerland.

摘要： The aim of the study is to determine the trajectories of physical activity and depressive symptoms and their reciprocal relationship among community-dwelling older adults in the COVID-19 pandemic era. The study population consisted of a cohort of 511 participants aged 60 years and over, who were recruited from eight community health centers in Ya'an, China. The Physical Activity Scale for the Elderly and the Patient Health Questionnaire were respectively used to measure physical activity and depressive symptoms at three time points: before the COVID-19 outbreak (T(0)), during the outbreak period (T(1)), and after the subsidence of COVID-19 (T(2)). The results revealed that physical activity and depressive symptoms fluctuated substantially across T(0), T(1), and T(2). In addition, more severe depressive symptoms at T(0) and T(1) were significantly associated with lower levels of physical activity at T(1) and T(2), but the obverse direction of physical activity being associated with subsequent depressive symptoms was not observed in the current study. These findings highlight the importance of supporting old people to remain physically active and combat mental distress early in a pandemic, and prevention and management of depressive symptoms may also be beneficial to promote physical activity.

关键词： prokaryotes;high throughput sequencing;biological information analysis;community structure

摘要： At present, research on the influence of human activities (especially urbanization) on the microbial diversity, structural composition, and spatial distribution of rivers is limited. In this paper, to explore the prokaryotic community structure and the relationship between the community and environmental factors in the Jialing River Basin of Chongqing, so as to provide a basis for monitoring microorganisms in the watershed. The V3–V4 region of the 16 S rRNA gene was analyzed by high-throughput sequencing and the microbial community of the waters of the Jialing River was analyzed for the diversity and composition of the prokaryotic community as well as the species difference of four samples and correlations with environmental factors. The main results of this study were as follows: (1) The diversity index showed that there were significant differences in the biodiversity among the four regions. At the genus level, Limnohabitans, unclassified_f_Comamonadaceae, and Hgcl_clade were the main dominant flora with a high abundance and evenness. (2) A Kruskal– Wallis H test was used to analyze the differences of species composition among the communities and the following conclusions were drawn: each group contained a relatively high abundance of Limnohabitans; the Shapingba District had a higher abundance of Limnohabitans, the Hechuan District had a wide range of unclassified_f_Comamonadaceae, and the Beibei District had a higher Hgcl_clade. (3) Through the determination of the physical and chemical indicators of the water—namely, total nitrogen, total phosphorus, chemical oxygen demand, chlorophyll A, and an analysis by an RDA diagram, the results demonstrated that the distribution of microbial colonies was significantly affected by the environmental factors of the water. Chemical oxygen demand and ammonia nitrogen had a significant influence on the distribution of the colonies. Different biological colonies were also affected by different environmental factors. © 2022 by the authors. Licensee MDPI, Basel, Switzerland.

摘要： This is the first study to assess nurses' attitudes and skills regarding grief counseling for bereaved family members of patients who died from coronavirus disease 2019 (COVID-19) in Wuhan, China. Using a cross-sectional design, 412 nurses selected through convenience sampling completed a demographic characteristics survey, Attitudes of Grief Counseling Scale, (AGCS) and Skills of Grief Counseling Scale (SGCS). Average AGCS score was 32.89 (SD = 9.46), with an overall percentage rate score of 65.6%. Factors influencing attitudes toward grief counseling included other grief counseling skills, educational level, communication skills, and training related to grief counseling (p < 0.05). Average SGCS score was 18.81 (SD = 4.25), with an overall percentage rate score of 58.7%. Factors influencing skills of grief counseling included responsibilities and roles, frequency of contact with the bereaved, and positive view of grief counseling (p < 0.05). Nurses' attitudes and skills regarding grief counseling were low, indicating an urgent need to improve grief counseling.
